To evaluate the safety and feasibility of prostatic artery embolization (PAE) via transradial access (TRA) compared with transfemoral access (TFA).This retrospective study included 53 consecutive men with lower urinary tract symptoms (LUTS) who underwent PAE between September 2018 and September 2021. Thirty-one patients (mean age ± standard deviation: 70.6 ± 8.4 years) were treated with TFA, including 14 patients treated before adopting TRA. Since December 2019, TRA has also been attempted with the procedure's selection criteria of patent carpal circulation and a height ≤ 172 cm, with 22 patients treated via TRA (69.1 ± 9.6 years). Parameters of technical success (defined as successful bilateral embolization), clinical success (defined as LUTS improvement), procedural time, radiation dose, and adverse events were compared between the two groups using the Fisher's exact test, independent sampleAll patients received at least one-side PAE. Technical success of PAE was achieved in most patients (TRA, 21/22; TFA, 30/31;PAE via TRA is a safe and feasible method comparable to conventional TFA. It can be safely implemented by selecting patients with patent carpal circulation and adequate height.

Purpose To investigate the correlation of the strain elasticity of breast cancer with histologic features, immunohistochemical markers and molecular subtypes that are known to be factors related to prognosis. Materials and Methods B-mode ultrasound and strain elastography were performed in 123 patients (mean age, 53.4; range, 28–82) with invasive ductal carcinoma (IDC) (mean size, 1.54 cm; range, 0.4–7.0 cm). Histologic grade, lymph node (LN) status, lymphovascular invasion, immunohistochemical biomarkers [estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 (HER2), CK5/6, epidermal growth factor receptor, and Ki-67] and molecular subtypes were determined from surgical pathology reports. The relationships between these factors and elasticity scores were evaluated. Results LN involvement was associated with a higher elasticity score which was statistically significant (p = 0.042). The tumor size, lymphovascular invasion, histologic grades, immunohistochemical markers and molecular subtypes had no significant correlation with the elasticity score (p > 0.05 for all). However, the IDCs with larger size and a positive lymphovascular invasion tended to have higher elasticity scores. Furthermore, higher histologic grade cancers and the HER2 overexpression-type tended to have lower elasticity scores. Conclusion The elasticity score of IDC had a significant correlation with LN involvement but no statistically significant correlation with the histologic features, immunohistochemical markers or molecular subtypes.

Background/aim Glioblastoma is the most malignant form of astrocytoma. The purpose of this study was to analyze the genetic characteristics of primary and recurrent glioblastomas using targeted sequencing and investigate the differences in mutational profiles between the locations of tumor recurrence. Materials and methods Fourteen glioblastoma patients who developed local (n=10) or distal (n=4) recurrence were included in the study. Targeted sequencing analysis was performed using the primary (n=14) and corresponding recurrent (n=14) tumor tissue samples. Results The local and distal recurrence groups showed different genetic evolutionary patterns. Most of the locally recurrent glioblastomas demonstrated concordant mutational profiles between the primary and recurrent tumors, suggesting a linear evolution. In contrast, all cases of distally recurrent glioblastomas showed changes in mutational profiles with newly acquired mutations when compared to the corresponding primary tumors, suggesting a branching evolution. Conclusion Locally and distally recurrent glioblastomas exhibit different evolutionary patterns.

The purpose of this study was to evaluate how the reference fat position influenced the calculation of the sonoelastographic strain ratio. Three hundred fifty-eight breast masses (256 benign lesions and 102 malignant lesions) in 300 women (mean age 47.4 years; age range 17–82 years) who had been scheduled for a percutaneous needle biopsy or surgical excision were examined using B-mode ultrasonography and elastography. The sonoelastographic strain ratio was calculated twice per lesion; once by dividing the strain value of the fat near the mass by that of the mass (FLR 1) and once by dividing the strain value of the subcutaneous fat by that of the mass (FLR 2). Most (91.9 %) showed a difference of less than 0.5 between FLR 1 and FLR 2 values. Regardless of the position of reference fat, there was no statistically significant difference between the FLR 1 and FLR 2 values (p value = 0.077 and 0.0825, respectively). According to the pathology of the lesion, a difference between FLR 1 and FLR 2 less than 0.5 occurred in 95.3 % of the benign lesions and 84 % of the malignant lesions (p

Uterine cervical cancer usually spreads by local extension and through the rich lymphatic network to the retroperitoneal lymph nodes. However, brain metastasis from primary cervical cancer is extremely rare. They are usually seen late in the clinical course and have poor prognosis. We present a 48-year-old woman with squamous cell carcinoma of the cervix who developed multiple brain metastases after 30-month treatment of the primary disease. The patient received whole brain radiation therapy and steroids, and she is alive without any neurologic symptoms and signs at the 6-month follow-up after treatment of the recurrence.

ObjectivesThe purpose of this study was to investigate the effectiveness of the mental health improvement programs in Korean firefighters through cooperation with the urban fire station. And we assessed the firefighter's degree of traumatic events and psychopathologies including depression, anxiety, suicidal ideation and insomnia.MethodsA mental health improvement program was provided to 502 firefighters working at Daegu, Gumi and Ulsan during 8-week period. The program included not only an evaluation and treatment of psychiatric symptoms through counseling but also a psychoeducation for mental health awareness. The validated Questionnaires to measure psychiatric symptoms were used; symptoms included depression, anxiety, suicidal thoughts and insomnia. Subjects were divided to two groups; PTSD high-risk group and non-high risk group. Psychopathological levels were compared before and after the program.ResultsPTSD high-risk group included 57 subjects (11.35%) and non-high risk group included 445 subjects (88.65%). Before the program, PTSD high-risk group showed higher depression, anxiety, insomnia scores statistically significant. Multiple logistic regression analysis with PTSD high-risk group as a dependent variable showed depression as a factor for firefighters to become PTSD high-risk group compared to those not depressed. Insomnia turned out to be another variant. The program resulted in significant decrease total scores of BDI and ISI for PTSD high-risk group.ConclusionsThe results on this study showed that higher levels of depression and insomnia especially influenced the manifestation of PTSD in firefighters. The evaluation and management of psychopathologies including depression, insomnia with traumatic events for firefighters can be helpful.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Ovarian cysts are primarily of follicular origin, and ovarian lymphangioma is an extremely rare lesion. Most ovarian cysts demonstrated on prenatal sonograms are asymptomatic and resolve antenatally. We report a case of ovarian torsion in utero secondary to an ovarian lymphangioma in which sonographic examination revealed a changing pattern of the cystic ovarian mass from an anechoic to echogenic appearance. © 2005 Wiley Periodicals, Inc.

Lee JW, Sohn KM, Jung HS he terms “ectopic pregnancy” and “extrauterine pregnancy” refer to a gestation anywhere outside the endometrial cavity of the uterus. The fallopian tubes are by far the most common sites of such pregnancy, whereas the ovary and abdominal cavity are less frequently involved [1]. The retroperitoneal space is an exceptional location. We describe a rare case of retroperitoneal pregnancy.

Objective This study was designed to evaluate the ultrasonographic (US) findings of medullary thyroid carcinoma (MTC) as compared to findings for papillary thyroid carcinoma (PTC). Materials and Methods The study included 21 cases of MTC that were surgically diagnosed between 2002 and 2007 and 114 cases of PTC that were diagnosed in 2007. Two radiologists reached a consensus in the evaluation of the US findings. The US findings were classified as recommended by the Thyroid Study Group of the Korean Society of Neuroradiology and Head and Neck Radiology (KSNHNR) and each nodule was identified as suspicious malignant, indeterminate or probably benign. The findings of medullary and papillary carcinomas were compared with use of the chi-squared test. Results The common US findings for MTCs were solid internal content (91%), an ovoid to round shape (57%), marked hypoechogenicity (52%) and calcifications (52%). Among the 21 cases of MTC nodules, 17 (81%) were classified as suspicious malignant nodules. The mean size (longest diameter) of MTC nodules was 19 ± 13.9 mm and the mean size (longest diameter) of PTC nodules was 11 ± 7.4 mm; this difference was statistically significant (p < 0.05). An ovoid to round shape was more prevalent for MTC lesions than for PTC lesions (p < 0.05). Conclusion The US criteria for suspicious malignant nodules as recommended by the Thyroid Study Group of the KSNHNR correspond to most MTC cases. The US findings for MTC are not greatly different from PTC except for the prevalence of an ovoid to round shape.
