• Misdiagnosis of appendicitis still occurs, especially in patients with equivocal radiological findings. • The sensitivity and specificity of CT followed by US exceeded those of CT alone. • After US re-evaluation, the negative appendectomy rate decreased from 3.4 to 2.3 %. • US re-evaluation in equivocal cases helps diagnostic confidence and further management.

To examine the prevalence of the Type D construct using the Korean version of the Type D Personality-14 (DS14) on the Korean youth population and to identify relationships between the Type D construct and other mental health measures. Adolescent participants aged 13-18 years were recruited from 12 schools (7 middle schools and 5 high schools) in Ansan city, located in the southwest area of Gyeonggi-do province, Korea. A total of 4,899 students were assessed with the Korean version of the DS14, Beck depression inventory (BDI), Korean Eppendorf Schizophrenia Inventory (K-ESI), Adolescent Mental health Problem behavior Questionnaire (AMPQ), and Alcohol Use Disorders Identification Test-Korean version (AUDIT-K). We found significant differences in all the measured scales and subscale scores between two groups, those with Type D personality and those without (BDI: p < 0.001, K-ESI: p < 0.001, AMPQ: p < 0.001, AUDIT-K: p < 0.001). When comparing the distributions of the high risk participants identified by the results of BDI, K-ESI, AMPQ, and AUDIT-K between participants with either Type D or non-Type D personality, a significantly higher proportion of high risk participants were in the Type D personality group according to all measures (BDI: p < 0.001, K-ESI: p < 0.001, AMPQ: p < 0.001, AUDIT-K: p < 0.001). In conclusions, Type D adolescents experience various and more severe mental health problems. Type D personality was more related with internalizing symptoms in Korean adolescents. DS14 can be useful in a community mental health program designed for adolescents.

The placement of pretrimmed PICCs by the blind pushing technique and primary brachial vein access is technically feasible and may represent an alternative to the conventional PICC placement technique, having low incidences of UEDVT and other complications, with no significant difference in outcomes between brachial vein and nonbrachial vein access.

Purpose:The purpose of this report is to retrospectively analyze the need for surgery, and the recurrence rate, using a CT-based method in patients with right colonic diverticulitis. Materials and Methods: For the purposes of our study, we included 416 patients with a mean age of 41.9 (238 of which were men), with a diagnosis of colonic diverticulitis that was based on CT findings. These findings were reviewed by two independent radiologists, who localized diverticulitis and determined it using a modified Hinchey classification. We were able to follow-up with 384 patients over a period of 30 months. Results: Out of the 416 patients, 396 of them had right colonic diverticulitis. In right colonic diverticulitis, the κ value in determining the modified Hinchey classification was 0.80. 98.2% (389/396) of the patients with right colonic diverticulitis had stages Ia-II. The surgery rate was 4.6% (17/366) and 28% (5/18) for right and left colonic diverticulitis, respectively (p < 0.001). In the instances of right colonic diverticulitis, the surgery rate was 2.8% (10/359) for stages Ia-II, while all seven patients with stage III or IV underwent surgery. The recurrence rate was 6.5% (23/356) and 15% (2/13) for right and left colonic diverticulitis, respectively (p = 0.224). Conclusion:The CT-based modified Hinchey classification of right colonic diverticulitis showed good interobserver agreement. Most patients with right colonic diverticulitis had lower stages (Ia-II) at the point of CT, rarely needed surgery, and had a low recurrence rate. Index termsCT Colon Diverticulitis Surgery Recurrence
