Ureteroarterial fistula is an extremely rare complication, but is associated with a high mortality rate. Previous pelvic surgery, long standing ureteral catheter insertion, radiation therapy, vascular surgery and vascular pathology contribute the development of this uncommon entity. Herein, a case of ureteroarterial fistula in a 69-year-old female patient, who presented with a massive hematuria, proven in a second attempt at angiography, is reported.

To determine the usefulness of MR axial images for diagnosis ACL tears, we reviewed MRIs of 67 patients with ACL tear confirmed by arthroscopic examination, retrospectively. There were 53 acute and 14 chronic tears. The axial MR images had a 97% sensitivity(acute: 96%, chronic: 100%). Findings of acute ACL tears on sequential axial imaging could be categorized as 1) diffuse swelling with abnormal substance signal in 14 cases(27.5%), 2) focal bulging or irregularity of medial border in 11 cases(21.6%) or 3) combination of the two in 26 cases(50.9%). Findings of chronic ACL tears also could be categorized as abnormally irregular thin fibers in 6 cases(42.9%) or nonvisualization(empty lateral wall) in 8 cases(57.1%). We concluded that MR axial images could provide additional useful information in the diagnosis of ACL tear.

Objective: In South Korea, the placement of orphans in institutions is still common, despite evidence of its adverse influence on children’s psychological, emotional, physical, and cognitive development. In this preliminary study, we evaluate whether system-wide positive behavior support (SWPBS) is effective for decreasing externalizing problems in institutionalized children. Methods: SWPBS was provided for one month to 36 school-aged boys who had lived in an orphanage for an average of 8.72 years (SD=2.52), along with their 10 caregivers. Direct observation of the frequency of target behaviors in the participating children, caregivers’ ratings of the severity of children’s problematic behaviors, self-reported caregiving stress (i.e., Parenting Stress Scale), and intervention fidelity were dependent variables. Results: After receiving SWPBS, the frequency of problematic behaviors in the participating children showed a mean decrease of 73.6%. The caregivers also reported seeing a decrease in the severity of their children’s problematic behaviors after SWPBS compared to before. Conclusion SWPBS may be a promising intervention to decrease externalizing behaviors in school-aged children who have been living in institutions for a long time and have shown mental health issues.

PURPOSE: The aim of this study was to examine the health-related behaviors related to a family history of cancer (FHCA) among Korean women underwent cancer screening. MATERIALS AND METHODS: A total of 8,956 women who underwent cancer screenings during 2001-2011 at the National Cancer Center, Korea, were analyzed. The association between health-related behaviors and a FHCA were assessed using multivariate logistic regression. RESULTS: Compared to women with no FHCA, women with FHCA were more likely to smoke (adjusted odds ratio [aOR], 1.32; 95% confidence interval [CI], 1.06 to 1.65), to be exposed to passive smoking (aOR, 1.21; 95% CI, 1.15 to 1.65), and less likely to engage in regular exercise (aOR, 1.20; 95% CI, 1.01 to 1.41). Combined effects of selected health behaviors for FHCA were significant, although no statistically significant interactions were observed between selected health behaviors. Compared to women with no FHCA, women with FHCA were more likely to simultaneously smoke and be exposed to passive smoking (aOR, 1.65; 95% CI, 1.17 to 2.31) and to simultaneously smoke and be physically inactive (aOR, 1.62; 95% CI, 1.00 to 2.64). CONCLUSION: The study found that women with a FHCA exhibited unhealthy behaviors compared to women without FHCA. Higher emphasis on lifestyle modifications using a new standardized tool is strongly recommended for those with a FHCA, as well as individuals who are at high risk, together with their family members.

As the number of elderly population increases, the proportion of edentulous patients is increasing, and the demand for traditional dentures will also increase. Arranging the artificial teeth according to the relationship and shape of the upper and lower alveolar ridge is an important factor increasing the stability of the denture. This case is a 79 year old female patient who wishes to make denture covered by national health insurance for psychological and economical reasons. With the alveolar bone severely atrophic, the dental CAD software was used for accurate diagnosis and the posterior teeth were arranged in a cross bite according to the interalveolar crest line angle by the program. After completion, the denture showed adequate stability and maintenance in periodic examinations and treatment, and the patient also expressed high satisfaction.

PURPOSE: Laparoscopic subtotal cholecystectomy (LSC) can be an alternative surgical technique for difficult cholecystectomies. Surgeons performing LSC sometimes leave the posterior wall of the gallbladder (GB) to shorten the operation time and avoid liver injury. However, leaving the inflamed posterior GB wall is a major concern. In this study, we evaluated the clinical outcomes of standard laparoscopic cholecystectomy (SLC), LSC, and LSC removing only anterior wall of the GB (LSCA). METHODS: We retrospectively reviewed the medical records of laparoscopic cholecystectomies performed between January 2006 to December 2015 and analyzed the outcomes of SLC, LSC, and LSCA. RESULTS: A total of 1,037 patients underwent SLC. 22 patients underwent LSC; and 27 patients underwent LSCA. The mean operating times of SLC, LSC, and LSCA were 41, 74, and 68 minutes, respectively (P < 0.01). Blood loss was 5, 45, and 33 mL (P < 0.05). The mean lengths of postoperative hospitalization were 3.4, 5.4, and 5.8 days. Complications occurred in 24 SLC patients (2.3%), 2 LSC patients (9%), and 1 LSCA patient (3.7%). There was no mortality among the LSC and LSCA patients. CONCLUSION: LSC and LSCA are safe and feasible alternatives for difficult cholecystectomies. These procedures help surgeons avoid bile duct injury and conversion to laparotomy. LSCA has the benefits of shorter operation time and less bleeding compared to LSC.

OBJECTIVE: To examine the effects of age, gender and bolus consistency in normal populations using the temporal measurement of Pharyngeal Transit Duration (PTD), which reflects the duration of bolus flow from the ramus of the mandible to the upper esophageal sphincter. METHOD: 40 normal and healthy subjects had Videofluoroscopic Swallowing Examinations (VFSEs) of 5 ml thin and nectar thick liquids, and puree consistencies. A slow motion and frame by frame analysis was performed. Three-way analysis of variance (ANOVA) was performed to examine the main effect and interactions, and paired t-tests for the three consistency comparisons. RESULTS: Older subjects had a significantly longer PTD than younger subjects (p<0.01). In addition, men had significantly shorter PTDs than women (p<0.01). Puree showed a significantly longer PTD than the other two consistencies, regardless of age and gender (p<0.05). CONCLUSION: PTD is an indicative of motor weakness in pharyngeal swallowing secondary to aging. In addition, the results supported the assumption that there is a functional difference in pharyngeal swallowing between men and women. It is expected that the results of this study will be used for further investigation of patients with dysphagia.

OBJECTIVE: To evaluate the impact of energy and access methods on extrahepatic tumor spreading and the ablation zone in an ex vivo subcapsular tumor mimic model with a risk of extrahepatic tumor spreading. MATERIALS AND METHODS: Forty-two tumor-mimics were created in bovine liver blocks by injecting a mixture of iodine contrast material just below the liver capsule. Radiofrequency (RF) ablations were performed using an electrode placed parallel or perpendicular to hepatic surface through the tumor mimic with low- and high-power protocols (groups 1 and 2, respectively). Computed tomography (CT) scans were performed before and after ablation. The presence of contrast leak on the hepatic surface on CT, size of ablation zone, and timing of the first roll-off and popping sound were compared between the groups. RESULTS: With parallel access, one contrast leak in group 1 (1/10, 10%) and nine in group 2 (9/10, 90%) (p < 0.001) were identified on post-ablation CT. With perpendicular access, six contrast leaks were identified in each group (6/11, 54.5%). The first roll-off and popping sound were significantly delayed in group 1 irrespective of the access method (p = 0.002). No statistical difference in the size of the ablation zone of the liver specimen was observed between the two groups (p = 0.247). CONCLUSION: Low-power RF ablation with parallel access is proposed to be effective and safe from extrahepatic tumor spreading in RF ablation of a solid hepatic tumor in the subcapsular location. Perpendicular placement of an electrode to the capsule is associated with a risk of extrahepatic tumor spreading regardless of the power applied.
