The authors dissected and examined a horseshoe kidney from the cadaver of a 54-year-old Korean female. The results were as follows. Other congenital anomalies or complications were not found, and no renal stones showed on plain radiography of the horseshoe kidney. The horseshoe kidney was located in the area between the 12 th thoracic vertebra and the 4th lumbar vertebra, with the superior extremity of the left kidney 10mm more inferior than that of the right. The isthmus connecting the bilateral kidneys was located at the level of the 3rd lumbar vertebra. The size of the kidney was 102mm × 52mm × 44mm (right) and 108mm × 62mm × 34mm (left), and the superoinferior and anteroposterior lengths of isthmus were 22mm and 10mm, respectively. The abdominal aorta and inferior vena cava passed posteriorly to the isthmus, with the inferior mesenteric artery and lumbar splanchnic nerve passing anteriorly. Some grooves were found on the anterior surface of the bilateral kidney. The hilum of the right kidney faced the anteromedial direction and that of the left kidney faced the anterolateral direction. At the hilar plane, the right renal arteries and veins passed anteriorly and posteriorly to the renal pelvis ; the left renal arteries passed posteriorly to the renal pelvis, with the left renal veins passing anteriorly and posteriorly. Three branches of the right renal arteries passed renal hilum, while two branches did not, and two branches of the left renal arteries passed renal hilum, while six branches did not. The two arteries arising from the aortic bifurcation were distributed to the isthmus. The number of renal veins passing the renal hilum were three in the right, and two in the left. The right and left ovarian veins drained to the renal veins. There were 12 minor calyces distributed normally in the right kidney, 13 minor calyces distributed radially in the left kidney, and 3 minor calyces in the isthmus, composed of parenchyme. The left portion of the horseshoe kidney was concluded to have developed poorly, on the basis of incomplete ascension and abnormal rotation during development, the imperfect configuration of the renal shape, and the abnormal distribution of the renal vessels and renal calyces.

PURPOSE: The purpose of this study is to evaluate the therapeutic efficacy, on the basis of CT findings, of high dose methyl prednisolone for treating acute lung injury that was induced by oleic acid injection. MATERIALS AND METHODS: A total of 30 healthy rabbits (1.8-2.2 kg) were included in this study. Group I included 10 rabbits in which 0.2 mL oleic acid was injected through their ear veins. Group IIa included 10 rabbits in which 30 mg/kg methyl prednisolone and 0.2 mL oleic acid were intravenously injected at the same time. Group IIb included 5 rabbits in which 30 mg/kg methyl prednisolone was injected 6 hours prior to the 0.2 mL oleic acid intravenous injection. The other 5 rabbits (Group III) were injected intravenously with 30 mg/kg methyl prednisolone without the oleic acid. After that, 30 mg/kg methyl prednisolone per every 12 hours was injected in the non-sacrificed rabbits of Group II and Group III. Nonenhanced Chest CT scans were performed prior to and 30 minutes, 4 hours, 24 hours, 48 hours, and 72 hours after the intravenous injection of oleic acid or methyl prednisolone. We randomly sacrificed one rabbit of groups I, II and III 30 minutes, 4 hours, 24 hours, 48 hours and 72 hours after CT scanning. The distribution, extent, and pattern of the lesions on the CT scan were analyzed. The analyzed pattern of the lesions was ground glass attenuation, consolidation and interstitial thickening. Pathologic correlation was then done. RESULTS: The main CT findings of Group I were peripheral, wedge shaped, ill-defined ground glass attenuations and/or consolidations. The pathologic findings of Group I were interstitial or intraalveolar edema, intraalveolar hemorrhage and coagulation necrosis. Diffuse ground glass opacities with interstitial thickening were noted in 20% (n=2/10) of Group I and in 60% (n=9/15) of Group II at the 30 minute CT; however, there was no statistical difference between the two groups (p=0.09). Consolidations with air bronchogram were noted in 22.2% (2/9) of Group I and in 38.5% (5/13) of Group II at the 4 hour CT. The main pathologic findings of consolidations were intraalveolar hemorrhage and coagulation necrosis. There was no statistical difference in the extent of the lesions between Group I and Group II (p=0.20, 0.14, 0.59 and 0.46 at 4, 24, 48 and 72 hours, respectively). The CT findings of Group IIa and Group IIb were not significantly difference. The CT findings of Group III were normal in all 5 rabbits. CONCLUSION: Because there was no significant difference for the extent of lung injury induced by oleic acid between the group treated with high dose methyl prednisolone and non-treated group on CT scans, high dose steroid therapy for acute respiratory distress syndrome and pulmonary fat embolism may not be effective in the acute stage.

PURPOSE: The purpose of this study was to examine the effects of music therapy on anxiety of patients in emergency room. METHODS: The study was designed using a noneqivalent control group nonsynchronized design. For 20 minutes, the experimental group(22 patients) had listened to music and the control group(23 patients) had bed rest. A six-item state anxiety scale developed by Marteau and Bekker, which was based on Spielberger's State-Trait Anxiety Inventory, blood pressure and pulse rate were measured to all study participants before and after the intervention. The data was analyzed by the SPSS 12.0 program. RESULTS: 1) The experimental group's state anxiety level were significantly lower than the control group's(t=2.220, p=.032). 2) There were no significant differences in both group's diastolic(t=-.495, p=.623) and systolic blood pressure(t=831, p=.411). 3) The experimental group's pulse rate was significantly lower than the control group's(t=2.363, p=.023). CONCLUSION: Music therapy may be applied as a nursing intervention to decrease anxiety in emergency room.

This report deals with a case of malakoplakia of urinary bladder in a 68 year old female. The lesion of malakoplakia has been misdiagnosed as a neoplasm on several occasions in other institutes. This disease has been reported seldomly, and many urologists and pathologists alike have been unfamiliar to the lesion. An emphasis on the clinicopathologic features is made in order to prevent the serious misdiagnosis. The pertinent literatures are reviewed.

BACKGROUND: Pusan is geographically far away from the indigenous area of malaria. It is the area where the tourists and foreigners travel through frequently because of the port. We investigated the situation in Pusan concerning malaria through the examination of malaria patients who contracted it recently. We found the ways to decrease erroneous diagnosis presuming malaria on the basis of these studies. METHODS: We retrospectively analyzed the medical records of 28 confirmed cases of malaria with the chief complaint of repeated high fever, who were admitted and treated in the Pusan Adventist Hospital and Pusan Samsun Hospital from June 1997 to August 2000. RESULTS: 25 cases were indigenous and 3 patients were imported cases contracted overseas. Peripheral blood smears revealed Plasmodium vivax in all indigenous cases, whereas 2 were P. falciparum and 1 case was P. vivax in the imported cases. Yeonchon-goon(9 cases) was the most prevalent area in the indigenous cases. Africa and Southeast Asia(3 cases) were the contracted areas in the imported cases. 27 cases were men and 1 case was a woman among the 28 cases, and the incidence was high peak in 8-10 month. Most of the patients(72.1%) were in the their 20's, and most of all had worked in the military bases near the demilitarized zone(DMZ). Thrombocytopenia and leukopenia were found more frequently by the laboratory findings. 23 of the cases(82%) were suspected to be malaria, before we confirmed it by peripheral blood smears. CONCLUSION: The number of patients with indigenous malaria from the other areas in Korea and patients with malaria from foreign countries will be expected to increase. Before we confirmed the malaria by peripheral blood smears, the cases suspected of malaria were 82.1%. This is a high diagnostic rate due to careful history taking and physical examination. The doctors decreased the rate of erroneous diagnosis of malaria and should be careful in the choice of the proper drugs.

Ectopic pregnancy is a common medical problem that is difficult to diagnose and potentially may lead to significant mortality or morbidity. The incidence of ectopic pregnancy is definitely increasing due to the rise in pelvic inflammatory disease (PID), pelvic surgery, intrauterine device (IUD), and assisted reproductive technologies, such as in vitro fertilization and embryo transfer (IVF-ET). Combined ectopic gestations are much rare and their true incidence is unknown. Multiple ectopic gestations may occur in a variety of locations. The majority involve one or both fallopian tubes. We report a case of combined tubal and cervical pregnancies, and discuss their management.

Background: The purpose of this study was to evaluate the differences in CT findings according to sputum smear- positive or -negative results in patients with active pulmonary tuberculosis having a single cavity. Methods: A total of 32 patients with active pulmonary tuberculosis having a single cavity on CT were classified into two groups: smear-positive (n=19) and smear-negative (n=13). The CT findings were reviewed retrospectively. The presence of consolidation, the number of lobes showing consolidation, ground-glass opacity, micronodules and nodule, the maximum diameter of the cavity, and the shape and maximum thickness of the cavity wall were assessed. Result: The maximum diameter of the cavity was 33.84 +/- 13.65 mm and 27.08 +/- 9.04 mm in the smear-positive and -negative groups, respectively (p>0.05). The amount of consolidation and the number of lobes with consolidation were found to be 89.5% and 30.8% (p=0.01) and 1.37 +/- 0.90 and 0.31 +/- 0.48 (p=0.0002) in the smear-positive and -negative groups, respectively. Consolidations in two or more lobes were only noted in 31.6% of in the sputum smear- positive group (p< 0.05). There were no other significant differences between the two groups. The sensitivity, specificity, positive and negative predictive values for the presence of consolidation were 89.5%, 69.2%, 73.9%, and 81.8%, respectively. Conclusion: While the absence of consolidation on CT may be associated with sputum smear-negative results in patients with active pulmonary tuberculosis having a single cavity, the presence of consolidation in two or more lobes on CT may be associated with spear-positive results in these patients.

The study of the ultrasonographic urethrogram on the male urethral stricture in 9 patients were performed. We could get the excellent three dimensional figures, which were demonstrating the nature of the urethral strictures in compared to the retrograde urethrogram. The ultrasonographic urethrography was useful in the diagnosis of the anterior urethral stricture, especially, but the delineation of the posterior urethra was difficult.

Oral squamous cell carcinoma (OSCC) is the most common oral malignancy and an increasing global public health problem. OSCC frequently invades the jaw bone. OSCC-induced bone invasion has a significant impact on tumor stage, treatment selection, patient outcome, and quality of life. A number of studies have shown that osteoclast-mediated bone resorption is a major step in the progression of bone invasion by OSCC; however, the molecular mechanisms involved in OSCC bone invasion are not yet clear. In this review, we present the clinical types of OSCC bone invasion and summarize the role of key molecules, including proteases, cytokines, and growth factors, in the sequential process of bone invasion. A better understanding of bone invasion will facilitate the discovery of molecular targets for early detection and treatment of OSCC bone invasion.
