We report a 43-year-old male who suffered cognitive dysfunction after an electric injury. He underwent evaluation for cognitive dysfunction and cerebral glucose hypometabolism at 1 week and 6 months. In contrast to the progressive decline of frontal lobe functions and visuospatial functions, memory and depressive mood were improved. SPM99 showed hypometabolic areas in the frontal and occipital lobes which were widened. Moreover new cingulate lesions appeared. This illustrates that the progression of derangement of cerebral glucose metabolism is correlated with neuropsychological impairment.

BACKGROUND: Despite the excellent early results after the repair of congenital bicuspid aortic valve (BAV) disease, the mid-term durability of the repaired valve has still controversies. MATERIAL AND METHOD: To evaluate the mid-term results of BAV repair, retrospective review of medical records and echocardiographic data were done. Between 1994 and 2003, twenty-two patients underwent reparative procedure for either regurgitant or stenotic congenital bicuspid aortic valve (BAV). RESULT: Mean age was 41+/-14 years with male predominance (Male=17, Female=5). The pathophysiologies of the BAV were regurgitation-dominant in 20 (91%) and stenosis-dominant in 2 (9%) cases. Various repair techniques were used for raphe, prolapsed leaflet, thickened leaflet, and commissures; 1) release of raphe in 19 (86%), 2) wedge resection and primary repair in 11 (50%), pericardial patch reinforcement after plication of the leaflet in 6 (27%), and plication of the leaflet in 3 (14%), 3) slicing of thickened leaflet was used in 12 (55%) cases, 4) commissuroplasty in 8 (36%), and commissurotomy in 6 (27%) cases. There was no in-hospital mortality. During the mean follow-up of 38+/-17 months, one patient underwent aortic valve replacement after developing acute severe regurgitation from dehiscence of the suture on postoperative 2 months. New York Heart Association functional class was improved from 1.9+/-0.6 to 1.2+/-0.5 (p<0.01). Left ventricular end-systolic and diastolic dimension (LVESD/LVEDD) were also improved from 45+/-9 and 67+/-10 to 37+/-10 and 56+/-10, respectively (p<0.01). The grade of aortic regurgitation (AR) was improved from preoperative (3.1+/-1.2) to post-bypass (0.9+/-0.7). However, the grade at last follow-up (1.7+/-1.1) was deteriorated during the follow-up period (p<0.01). Freedom from grade III and more AR at one, three, and four year were 89.7%, 89.7%, and 39.9% respectively. CONCLUSION: Midterm clinical result of the BAV repair was favorable. But, the durability of the repaired valve was not satisfactory.

As classical acute aortic dissection, atherosclerotic penetrating ulcers and intramural hematoma have different pathophysiology and natural history, treatment strategy should be different and, therefore, accurate differential diagnosis is necessary. However, these three aortic diseases may be indistinguishable by clinical observation and even by various diagnostic modalities such as cardiac echocardiography, CT and MRI. The patients was a 71-year-old female with chief complaints of anterior chest pain, nausea and vomiting which occurred suddenly 3 days before admission. CT angiography with 3 dimensional reconstruction shows intramural hematoma in ascending aorta, aortic arch, descending thoracic aorta and right brachiocephalic trunk, hemopericardium, and blood in mediastinum and both pleural cavities. The CT angiographic finding of focal out-bulging in the ascending thoracic aorta was diagnosed as penetrating atherosclerotic ulcer. The patient underwent emergency operation under a preoperative diagnosis of penetrating atherosclerotic ulcer with a sign of aortic rupture. In the intraoperative findings, however, intimal tear was seen in the anterior portion of the ascending aorta about 1cm below the brachiocephalic trunk and falselumen appeared after hematoma was removed from the layer of tunica media. We report a case of type A aortic dissection which mimicked clinical and diagnostic features of penetrating atherosclerotic ulcer.

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components. MUC-1 was expressed at the stromal edge of the micropapillary component. The other tumor was composed of atypical carcinoid-like neuroendocrine carcinoma (50%), adenocarcinoid (30%), and adenocarcinoma components (20%). The neuroendocrine components were positive for CD56, synaptophysin, chromogranin, and creatine kinase. The adenocarcinoid components were positive for both carcinoembryonic antigen and neuroendocrine markers (amphicrine differentiation). This case is unique, due to the peculiar histologic micropapillary pattern and the histologic spectrum of adenocarcinoma adenocarcinoid-neuroendocrine carcinoma of the synchronous composite tumor.

A 50-year-old woman who had chronic headache was admitted to the hospital. Stent-assisted coil embolization of the aneurysm in the right vertebral artery was performed. After the procedure, the patient experienced a transient memory impairment. A microembolic lesion in the right medial temporal lobe and cerebral hemisphere was observed on diffusion-weighted imaging. We report a case of transient global amnesia caused by microembolus in the medial temporal lobe after embolization of an aneurysm.

BACKGROUND: Anatomic footprint restoration of anterior cruciate ligament (ACL) is recommended during reconstruction surgery. The purpose of this study was to compare and analyze the femoral and tibial tunnel positions of transtibial single bundle (SB) and transportal double bundle (DB) ACL reconstruction using three-dimensional computed tomography (3D-CT). METHODS: In this study, 26 patients who underwent transtibial SB ACL reconstruction and 27 patients with transportal DB ACL reconstruction using hamstring autograft. 3D-CTs were taken within 1 week after the operation. The obtained digital images were then imported into the commercial package Geomagic Studio v10.0. The femoral tunnel positions were evaluated using the quadrant method. The mean, standard deviation, standard error, minimum, maximum, and 95% confidence interval values were determined for each measurement. RESULTS: The femoral tunnel for the SB technique was located 35.07% +/- 5.33% in depth and 16.62% +/- 4.99% in height. The anteromedial (AM) and posterolateral (PL) tunnel of DB technique was located 30.48% +/- 5.02% in depth, 17.12% +/- 5.84% in height and 34.76% +/- 5.87% in depth, 45.55% +/- 6.88% in height, respectively. The tibial tunnel with the SB technique was located 45.43% +/- 4.81% from the anterior margin and 47.62% +/- 2.51% from the medial tibial articular margin. The AM and PL tunnel of the DB technique was located 33.76% +/- 7.83% from the anterior margin, 45.56% +/- 2.71% from the medial tibial articular margin and 53.19% +/- 3.74% from the anterior margin, 46.00% +/- 2.48% from the medial tibial articular margin, respectively. The tibial tunnel position with the transtibial SB technique was located between the AM and PL tunnel positions formed with the transportal DB technique. CONCLUSIONS: Using the 3D-CT measuring method, the location of the tibia tunnel was between the AM and PL footprints, but the center of the femoral tunnel was at more shallow position from the AM bundle footprint when ACL reconstruction was performed by the transtibial SB technique.

OBJECTIVES: Ciprofloxacin, one of the most widely used fluoroquinolone, has been used for some abdominal and genitourinary infections in emergency departments (EDs). This investigation was performed to identify the risk factors of inappropriate use of ciprofloxacin in the ED. METHODS: We retrospectively reviewed the medical records of patients who had visited the ED of Seoul National University Hospital from January 2002 to December 2002 and who had been prescribed ciprofloxacin as an initial empirical antibiotic. The appropriateness of ciprofloxacin use was judged according to existing institutional guidelines. RESULTS: Of the total 577 patients (219 males, mean age 53.0+/-17.1; 358 females, mean age 50.3+/-18.7), ciprofloxacin was used appropriately in 289 (50.1%). In the univariate analysis, gender, site of suspected infection, route of administration, and disposition were significantly different between the appropriate and the inappropriate use groups (p<0.005). In multivariate analysis, the adjusted odds ratio for related factors for inappropriate ciprofloxacin use was significantly higher in old age patients (>65 years old) than in younger patients (under 30 years old; OR=2.02, 95% CI=1.01-4.03), in patients having the GI tract infections than in patients having genitourinary tract infections (OR=14.28, 95% CI=8.76-23.29), in patients who were administered orally than intravenously (OR=2.45, 95% CI=2.08-5.71), and in patients who stayed in the ED than in those who were admitted (OR=4.29, 95% CI=1.98-9.34). CONCLUSION: Inappropriate use of ciprofloxacin in the ED is very common. If the emergence of ciprofloxacin resistance is to be avoided, education and efforts for judicious use of ciprofloxacin are warranted.

BACKGROUND: Regarding reconstruction surgery of the anterior cruciate ligament (ACL), there is still a debate whether to perform a single bundle (SB) or double bundle (DB) reconstruction. The purpose of this study was to analyze and compare the volume and surface area of femoral and tibial tunnels during transtibial SB versus transportal DB ACL reconstruction. METHODS: A consecutive series of 26 patients who underwent trantibial SB ACL reconstruction and 27 patients with transportal DB ACL reconstruction using hamstring autograft from January 2010 to October 2010 were included in this study. Three-dimensional computed tomography (3D-CT) was taken within one week after operation. The CT bone images were segmented with use of Mimics software v14.0. The obtained digital images were then imported in the commercial package Geomagic Studio v10.0 and SketchUp Pro v8.0 for processing. The femoral and tibial tunnel lengths, diameters, volumes and surface areas were evaluated. A comparison between the two groups was performed using the independent-samples t-test. A p-value less than the significance value of 5% (p < 0.05) was considered statistically significant. RESULTS: Regarding femur tunnels, a significant difference was not found between the tunnel volume for SB technique (1,496.51 +/- 396.72 mm3) and the total tunnel volume for DB technique (1,593.81 +/- 469.42 mm3; p = 0.366). However, the total surface area for femoral tunnels was larger in DB technique (919.65 +/- 201.79 mm2) compared to SB technique (810.02 +/- 117.98 mm2; p = 0.004). For tibia tunnels, there was a significant difference between tunnel volume for the SB technique (2,070.43 +/- 565.07 mm3) and the total tunnel volume for the DB technique (2,681.93 +/- 668.09 mm3; p < or = 0.001). The tibial tunnel surface area for the SB technique (958.84 +/- 147.50 mm2) was smaller than the total tunnel surface area for the DB technique (1,493.31 +/- 220.79 mm2; p < or = 0.001). CONCLUSIONS: Although the total femoral tunnel volume was similar between two techniques, the total surface area was larger in the DB technique. For the tibia, both total tunnel volume and the surface area were larger in DB technique.
