Therapeutic ionizing radiation can damage the permanent pacemaker. Reimplantation of pacemaker should be considered when the pacemaker site is included in the radiation field. We report a case of successful repositioning of preexisting pacemaker generator and leads with subcutaneous tunneling method across the sternum instead of insertion of new leads in a female patient with breast cancer who had DDD pacemaker.

This study describes an evaluation of the sonographic, cholangiographic, pathological, and immunological findings, and the protective effect shown by rats reinfected with Clonorchis sinensis. Eight experimental rat groups were, namely, a normal control, a primary infection control, a reinfection I (reinfection 7 week after treatment following 3-week infection), a reinfection II (reinfection 2 week after treatment following 8-week infection), a reinfection III (exploration of the intrahepatic bile ducts 1 week after reinfection 4 week after treatment following 4-week infection), a superinfection, a secondary infection control, and an infection following immunization group. Sonographic and cholangiographic findings showed moderate or marked dilatation of the bile duct confluence in the primary infection control, reinfection II, and secondary infection control groups. Juvenile worms survived in the intrahepatic bile ducts 1 week after reinfection following treatment in the reinfection III group. It was concluded that reinfecting juvenile worms found during the first week following reinfection failed to survive or grow further. Anatomical, pathophysiological, or immunological changes may induce protection from reinfection in rats.

The purpose of this study was to investigate the specific cognitive emotion regulation strategies affecting the development and maintenance of post-traumatic stress symptoms by reviewing the related literature. A literature search was conducted using Google Scholar, PubMed, DBPia, and RISS for investigating the relationship between cognitive emotion regulation strategies and post-traumatic stress symptoms in people with post-traumatic stress disorder (PTSD) or in those who had experienced severe trauma. Catastrophizing and rumination were associated with more post-traumatic stress symptoms and higher psychological distress. On the other hand, positive reappraisal, refocus on planning, and acceptance were associated with fewer post-traumatic stress symptoms and lower psychological distress. We propose that catastrophizing and rumination contribute to both the development and maintenance of post-traumatic stress symptoms. Therefore, in the prevention and treatment of PTSD symptoms, catastrophizing and rumination need to be targeted and positive reappraisal needs to be increased.

Objective: Patients with post-traumatic stress disorder (PTSD) showed inconsistencies in their cortisol level, an index of the hypothalamic-pituitary-adrenal axis function. This study examined the relationship between dissociation, childhood trauma, and morning cortisol levels in PTSD patients. Methods: This study included 69 (23 males and 46 females) patients and 82 (22 males and 60 females) healthy controls (HCs). Clinical assessments, including the Childhood Trauma Questionnaire (CTQ) and Peri-traumatic Dissociative Experiences Questionnaire scores, and morning cortisol levels were evaluated. The morning cortisol levels were compared between PTSD with high dissociation and low dissociation (PTSD-LD) groups. The effect of CTQ subtype on morning cortisol levels was analyzed. Results: The PTSD with high dissociation group showed significantly lower cortisol levels than that of the PTSD-LD and HC groups. A significant inverse correlation was found between cortisol levels and dissociation. A significant positive correlation was found between dissociation and physical abuse and sexual abuse scores. Morning cortisol levels showed a significant positive correlation with emotional abuse, emotional neglect, and physical neglect, respectively. There was no moderating or mediating effect of CTQ on the relationship between cortisol level and dissociation. Conclusion These findings suggest that dissociation is a significant factor related to hypocortisolism in PTSD patients.Additionally, basal morning cortisol levels and dissociation scores were closely associated with childhood trauma.

OBJECTIVE: The aim of this study is to investigate the effects of cooperative training on the pretreatment assessment of the feasibility to perform Ultrasonography (US) guided percutaneous radiofrequency ablation for patients afflicted with hepatocellular carcinoma. MATERIALS AND METHODS: In our prospective study, 146 patients with 200 hepatocellular carcinomas were referred for radiofrequency ablation after triage by hepatologists. Three radiologists with different levels of experience performed the planning US before (group I) and after (group II) cooperative training, to evaluate whether radiofrequency ablation was feasible. The feasibility rates considered eligible according to our criteria were evaluated. In addition, we analyzed the reasons for the lack of feasibility were analyzed. The interobserver agreement for the assessment of feasibility before and after training was also calculated. RESULTS: The overall feasibility rates for both groups was 73%. No significant difference in the feasibility rates was observed. The feasibility rates of each observer for group I were 71% (observer 1), 77% (observer 2) and 70% (observer 3) and those for group II were 73%, 76% and 69%, respectively. In the tumors (n = 164) considered ineligible, the two most common causes for refraining from performing radiofrequency ablation included non-visualization of the tumor (62%) and the absence of a safe route for the percutaneous approach (38%). We found moderate interobserver agreement for all observers before cooperative training and a good agreement after training. CONCLUSION: Although the cooperative training did not affect the feasibility rate of each observer, it improved the interobserver agreement for assessing the feasibility of performing US guided radiofrequency ablation, which may reduce unnecessary admission or delayed treatment.

PURPOSE: Small uterine cervical tumors are often undetected on MRI, and undetectable tumors are usually regarded as being in their early stages. The purpose of this study was to evaluate morphological factors determining MRI detectability of uterine cervical tumors by comparing detected and undetected tumors using high resolution MRI units. MATERIALS AND METHODS: Sixty-six surgically-proven uterine cervical cancer patients were included in this study. Using a GE Signa 1.5T magnet (GE, U.S.A.) axial T1-weighted MR images and axial, sagittal, and coronal T2-weighted fast spin echo MR images were obtained with a 5 mm thickness/2 mm gap and a 512x256 matrix size. The patients were divided into two groups, tumor-detected and tumor-undetected. Maximal tumor dimension, depth of stromal invasion, and horizontal tumor spread, measured during histopathological examinations, as well as pathological stages, were compared between the two groups. RESULTS: In the tumor-detected group, the pathological stages were IB1 in 25, IB2 in 3, IIA in 10, and IIB in 5 patients; in the tumor-undetected group, the stages were IA1 in 8, IA2 in 2, and IB1 in 13 patients. Maximal tumor dimension, depth of stromal invasion and horizontal tumor spread for tumor-detected and -undetected groups were 27.4 (10-60) mm vs. 10.4 (3-40) mm (p=0.077), 11.1 (3-20) mm vs. 2.3 (0-5) mm (p<0.001), and 26.6 (8-60) mm vs. 10.4 (3-40) mm (p=0.057), respectively. CONCLUSION: Of the criteria studied, depth of stromal invasion is the most important factor in determining tumor detectability on MRI. All tumors in which this depth was more than 5 mm were thus detected; which are undetected on high resolution MRI can be regarded as early-stage tumors (stage IB1).

We measured changes in sonographic findings of patients with clonorchiasis after a treatment in a highly endemic area. A total of 347 residents showed positive stool results for Clonorchis sinensis eggs in a village in northeastern China, and were treated with praziquantel. Of them, 132 patients underwent abdominal sonography both before and 1 year after treatment, and the changes in sonographic findings of 83 cured subjects were compared. Diffuse dilatation of intrahepatic bile ducts (DDIHD) was found in 82 patients (98.2%) before and 80 (96.4%) after treatment, which was improved in 3, aggravated in 1, and unchanged in 79 patients. Increased periductal echogenicity (IPDE) was observed in 42 patients (50.6%) before and 45 (54.2%) after treatment, which was improved in 5, aggravated in 8, and unchanged in 70 patients. Floating echogenic foci in the gallbladder (FEFGB) was detected in 32 patients (38.6%) before and 17 (20.5%) after treatment, which was improved in 20, aggravated in 5, and unchanged in 58 patients. Improvement of FEFGB only was statistically significantly (P = 0.004). The present results confirm that DDIHD and IPDE persist but FEFGB decreases significantly at 1 year after treatment. In a heavy endemic area, the sonographic finding of FEFGB may suggest active clonorchiasis 1 year after treatment.

PURPOSE: Pelvic irradiation for the treatment of cancer can affect normal cells, such as the rapidly proliferating spermatogenic cells of the testis, leading to infertility, a common post-irradiation problem. The present study investigated the radioprotective effect of rolipram, a specific phosphodiesterase type-IV inhibitor known to increase the expression and phosphorylation of the cyclic adenosine monophosphate response element-binding protein (CREB), a key factor for spermatogenesis, with the testicular system against pelvic irradiation. MATERIALS AND METHODS: Male C57BL/6 mice were treated with pelvic irradiation (2 Gy) and rolipram, alone or in combination, and were sacrificed at 12 hours and 35 days after irradiation. RESULTS: Rolipram protected germ cells from radiation-induced apoptosis at 12 hours after irradiation and significantly increased testis weight compared with irradiation controls at 35 days. Rolipram also ameliorated radiation-induced testicular morphological changes, such as changes in seminiferous tubular diameter and epithelial height. Additionally, seminiferous tubule repopulation and stem cell survival indices were higher in the rolipram-treated group than in the radiation group. Moreover, rolipram treatment counteracted the radiation-mediated decrease in the sperm count and mobility in the epididymis. CONCLUSIONS: These protective effects of rolipram treatment prior to irradiation may be mediated by the increase in pCREB levels at 12 hours post-irradiation and the attenuated decrease in pCREB levels in the testis at 35 days post-irradiation in the rolipram-treated group. These findings suggest that activation of CREB signaling by rolipram treatment ameliorates the detrimental effects of acute irradiation on testicular dysfunction and the related male reproductive functions in mice.
