BACKGROUND: Urography(IVU) is considered the best first investigation in patient with suspected urinary calculi, but recently ultrasonography(USG), combined with a plain film of the abdomen, has been suggested as an alternative. METHODS: We undertaken study to see if this approch can be used in emergency patients and outpatients by radiologists with different amounts of ultrasound experence. Some 192 patients with suspected urinary colic presenting to Koo Hospital Emergency Department and Youngnam Universith Hospital outward Department(IM, URO, FM) over 12-month period were studied. They had a plain abdominal film(KUB) and USG examination of the kidney, ureter, bladder following hydration and subsequently underwent IVU. Of these, 22 patients passed a stone before their IVU. The data analysis was performed on the remaining 170 patients. Urography was used as the gold standard. RESULTS: Some 170 patients subsequently underwent IVU at a mean interval of 1.8 days after the ultrasound examination. In 91 of 170 patients the IVU was positive. In 97 of 170 patients the combination of JUB plus USG was positive, leaving three false negative KUB plus USG. Thus the sensitivity of KUB plus USG was 97%, specificity was 89%, positive predictive value was 91%, and negative predictive value was 96%. CONCLUSIONS: Our findings in this study suggest that in the hydrated patient the combination of KUB plus US is a very sensitive and relative specific screening test. Because of the high negative predictive value of KUB plus US, urography is not likely to be helpful when KUB plus US are negative. Urography is indicated only if KUB plus US findings are equivocal or if intervention is necessa.ry.

Extrapelvic endometriosis is a rare disease. The majority of extrapelvic endometriosis cases involve scar tissue following obstetric and gynecologic procedures. We have treated two cases of extrapelvic incisional endometriosis. A 39 year old female patient with cyclic vaginal spotting after laparoscopic assisted vaginal hysterectomy due to uterine myoma and a 35 year old female patient with a painful palpable abdominal mass after cesarean section. Both underwent complete excision and were proven to have endometriosis by pathology. Here we report on both cases and review the medical literatures.

PURPOSE: To evaluate surgical effect of Medpor(R) Barrier Sheet, by comparing with postoperative outcomes using Medpor(R) Barrier Sheet and Medpor(R) in orbital wall reconstruction. METHOD: We have retrospectively analyzed clinical features and postoperative outcomes in two groups. One group is 29 patients who had undergone orbital wall reconstruction using Medpor(R) Barrier Sheet, the other group is 26 patients who had undergone orbital wall reconstruction using Medpor(R). RESULTS: The violence was the most common cause of the orbital wall fractures, the most common fracture site was inferior wall in the two groups. There were no significant differences between the two groups in improvement of diplopia and limitation of extraocular movement(p>0.05). The mean amount of enophthalmic correction were 1.15 mm in Medpor(R) Barrier Sheet group and 1.39 mm in Medpor(R) group. Three cases of Medpor(R) Barrier Sheet group and two cases of Medpor(R) group caused the infraorbital hypoesthesia, but prolapse or dislocation of implant was not found in the two groups. CONCLUSIONS: In this study, Medpor(R) Barrier Sheet had similar surgical effect to regular Medpor(R); its advantages over regular Medpor(R) were easy intraoperative manipulation and less adherence of extraocular muscle in reconstruction of orbital wall fractures. But when cost- effectiveness is considered, Medpor(R) Barrier Sheet may be a good available implant in orbital wall reconstruction for the selective cases with extraocular muscle exposed.

Aniridia is a relatively rare congenital anomaly and its incidence is about 1:100, 000.Main features of aniridia include congenitally partial or nearly complete absence of the iris and hypoplasia of optic disc and fovea. It is almost bilateral and occurred as an autosomal dominant trait.However, some patients develop both sporadic nonfamilial aniridia and Wilms 'tumor, and another group of patients is transmitted as an autosomal recessive trait. We observed aniridia in two generations, as mother and two daughters. They had cataract, nystagmus, neovascularization of corneal margin and pannus formation, as well as aniridia.We also found hypoplasia of optic disc and fovea in mother. We have operated on mother with phacoemulsified lens aspiration and posterior chamber IOL implantation in both eyes consecutively.The postoperative visual acuity following lens extraction improved, but was not corrected. In addition, intraocular pressure decreased.

PURPOSE: We present our results in the reconstruction of medial orbital wall fractures using a transcaruncular approach. METHODS: Forty-five patients with isolated medial orbital wall fractures underwent reconstruction by transcaruncular approach in our clinic between May 2003 and October 2007, and were followed up for 6 months or more. RESULTS: Thirty-three males and 12 females were included in this study, with a mean age of 34.9 years. The most common indication for reconstruction were large sized fractures more than 50%. Operations were performed at a mean 11.9 days after trauma. Among 18 patients who had diplopia before the operation, 16 (89%) patients had symptom relief or improvement, and in the 2 patients where diplopia persisted, it did not in primary and down gaze and offered no difficulties in daily activities. Among 34 patients who had enophthalmos before the operation, most (n=30) of the patients had minimal enophthalmos not more than 2 mm, 4 patients had enophthalmos that exceeded 2 mm. CONCLUSIONS: Transcaruncular approach in reconstruction of isolated medial orbital wall fracture shows more satisfying functional and cosmetic results and can be preferred to isolated medial orbital wall fracture.

Purpose: To measure the level of reflection, this study analyzes diaries written by third-year nursing students before and after the debriefing stage in simulation training. A qualitative study using diary entries from 15 nursing students to explore reflection depth. Methods: Students engaged in simulation training and the debriefing stage, documenting their reflections in diaries. Before and after debriefing, reflections were rated from Level 1 (reflectivity) to Level 7 (theoretical reflectivity). Results: The total number of reflection levels rose significantly from 545 to 829 post-debriefing, enhancing higher-order reflection.The shift signifies a move from superficial to deep reflection, highlighting debriefing's role in fostering critical thinking. Conclusion The findings underscore the critical role of debriefing in enhancing reflective thinking in nursing education. There is a demonstrated need for further research into the specific elements of debriefing that are most effective at promoting deep reflection. Future studies should conduct comparative analyses of different debriefing methods and approaches across various educational settings. This research could lay the foundation for designing more effective debriefing strategies that foster critical thinking and improve learning outcomes in nursing education.

PURPOSE: The aim of this study was to estimate the antioxidant activities of 50%, 70%, and 100% ethanol extracts of Lycium barbarum leaf and chlorophyll removal extract. METHODS: The antioxidant activities were estimated by measuring total polyphenol content and by assays of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfate) (ABTS) radical scavenging activities and ferric reducing antioxidant power (FRAP). In addition, reactive oxygen species (ROS) production, DNA fragmentation, and antioxidant enzyme (superoxide dismutase and catalase) activities of the extracts were measured in hydrogen peroxide (H2O2)-stressed HepG2 cells. RESULTS: The total polyphenol content, DPPH and ABTS radical scavenging activities, and FRAP value of the extracts increased in an ethanol concentration-dependent manner. The antioxidant activities of the chlorophyll-removal extracts were much higher than those of the chlorophyll-containing extracts. Cytotoxicity was not observed in HepG2 cells with extracts up to 1,000 µg/mL. All extracts inhibited ROS production in a concentration-dependent manner from 31.3 µg/mL and inhibited DNA damage at 250 µg/mL. The SOD and catalase activities of cell lines treated with the extracts and H2O2 were similar to those of normal cells, indicating a strong protective effect. CONCLUSION: Lycium barbarum leaf extracts had high antioxidant activities and protected H2O2-stressed HepG2 cells. Since the chlorophyll-removal extract exhibited higher antioxidant activities than the chlorophyll-containing ones and the cytoprotective effect was similar, chlorophyll removal extract of Lycium barbarum leaf could be developed as ingredients of functional food and cosmetics.

PURPOSE: Evidence suggests that some patients with breast cancer experience cognitive difficulties following chemotherapy. This longitudinal study was done to examine the prevalence of cognitive impairment and trajectory of cognitive function over time in women with breast cancer, who received adjuvant chemotherapy. METHODS: Participants were 137 patients with breast cancer. They completed neuropsychological tests and the Functional Assessment of Cancer Therapy-Cognitive Function before adjuvant therapy (pretest), toward the end of adjuvant therapy (posttest), and 6 months after the completion of adjuvant therapy (follow-up test). Of the patients, 91 were treated with adjuvant chemotherapy and 46 patients who did not receive chemotherapy made up the comparison group. A reliable-change index and repeated-measure ANOVA were used for statistical analyses. RESULTS: At the posttest point, over 30% of patients showed complex cognitive impairment and reported greater difficulty in subjective cognitive function. At the follow-up test point, 22.0% of patients exhibited complex cognitive impairment and 30.8% of patients complained of subjective cognitive impairment. Repeated-measure ANOVA showed significant decreases after receiving chemotherapy followed by small improvements 6 months after the completion of chemotherapy in cognitive domains of change for attention and concentration, memory, executive function, and subjective cognitive function. CONCLUSION: These results suggest that chemotherapy in patients with breast cancer may be associated with objective and subjective cognitive impairments. Further studies are needed to explore the potential risk factors and predictor of chemotherapy-related cognitive changes. Also nursing interventions for prevention and intervention of cognitive impairments should be developed and tested.
