1.Primary Stent Placement for Chronic Spontaneous Infrarenal Abdominal Aortic Dissection: A Case Report.
Journal of the Korean Radiological Society 2007;56(4):321-325
Spontaneous infrarenal abdominal aortic dissection (SIAAD) is a rare entity with various clinical presentations. We recently encountered the even rarer condition of a female patient suffering from chronic SIAAD with multiple intimal flaps and prominent lumbar artery collaterals; this all caused stenotic changes of the infrarenal abdominal aorta and produced progressive lower extremity pain and claudication in both her legs. This patient's condition was successfully managed by primary stent placement followed by balloon angioplasty.

The Neurosensory retinal detachment contributes to the visual loss in the idiopathaic macular holes. Vitrectomy can be performed to reattach the retina by removing anterior-posterior and tangential traction between cortical vitreous and macular surface. Also bioadhesives, like autologous serum or platelets aggregates are used to flatten of surrounding rim detachment of macular holes. Among 22 eyes that underwent vitrectomy for the treatment of macular holes, anatomic success was achieved in 12 eyes (59.1%), and visual improvement in 10 eyes (45.5%). The time interval between diagnosis and operation was well-correlated to the functional success rate, while the type of surgical procedures was not. Postoperative complications included 2 cases of cataract, and 1 case of retinal detachment.

Although cervical epidural abscess is rare, it should be strongly suspected in any patient with unexplainable neck pain and fever, especially when the patient has a predisposing factor for this infectious process. The authors report a case of cervical epidural abscess in a 39-yr-old man with an aorto-duodenal fistula, which complicated the interposition of artificial graft for abdominal aortic aneurysm rupture, which had undertaken 40 months before. Timely detection and intervention rendered him a full neurological recovery. This extremely rare case is presented with a literature review.

Gastrointestinal (GI) fistulae are defined as an abnormal communication between the gastrointestinal tract and the skin and/or the epithelial surface of an adjacent viscus. GI fistulae are the most feared complications caused by a variety of medical conditions including abdominal surgery, inflammatory bowel disease, abscess, radiation, or trauma. The management of GI fistulae is complex and requires a detailed, stepwise approach to achieve successful closure. The ultimate goal of management is to re-establish the continuity of the GI tract, while limiting the morbidity and mortality. Interventional radiology can play an important role in the diagnosis and treatment of GI fistulae. In this article, we review the clinical and radiologic features and interventional treatment of GI fistulae.

Purpose:
The relationship between microsatellite instability (MSI) and tumor response after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer remains unclear. The present study aimed to evaluate the association between MSI and tumor response to nCRT in rectal cancer treatment.
Methods:
Patients with rectal cancer from 2 tertiary hospitals who underwent nCRT, followed by radical surgery, were included. The microsatellite status was determined using a PCR-based Bethesda panel. Tumors with a Dworak’s tumor regression grade of 3 or 4 were considered to have a good response. Predictive factors for a good response to nCRT were analyzed.
Results:
Of the 1,401 patients included, 910 (65.0%) had MSI results and 1.5% (14 of 910) showed MSI-H. Among all the patients, 519 (37.0%) showed a good response to nCRT. A univariate analysis showed that MSI-H tended to be negatively associated with a good response to nCRT, but no statistical significance was observed (7.1% vs. 24.1%, P = 0.208).Multivariate analysis showed that well-differentiated tumors were the only predictive factor for good response to nCRT (odds ratio [OR], 2.241; 95% confidence interval [CI], 1.492–3.364; P < 0.001). MSI status tended to be associated with the response to nCRT (OR, 0.215; 95% CI, 0.027–1.681; P = 0.143).
Conclusion
MSI-H was not associated with response to nCRT in patients with rectal cancer.

BACKGROUND AND PURPOSE: Caregivers endure tremendous physical, emotional, and financial burdens while caring for people with dementia. The current study aimed to estimate the effectiveness of cognitive behavioral therapy (CBT) for caregivers of people with dementia (CGPWD). METHODS: Studies in the MEDLINE, EMBASE, Cochrane Library, Web of Science, and SCOPUS databases were screened. Studies with a randomized controlled design and which produced CBT outcomes for CGPWD were included in this study, and we investigated these outcomes. RESULTS: The screening of abstracts of 263 studies resulted in 12 randomized controlled trials being included in this study. The mean age of the CGPWD ranged from 51.5 to 66.2 years. The caregiver role was most frequently adopted by a female spouse or daughter. CBT for the CGPWD resulted in positive effects on various conditions, including depression, anxiety, stress, and dysfunctional thoughts. Depression was the most commonly evaluated condition, and the Center for Epidemiologic Studies Depression Scale (CES-D) was most frequently used as an inventory for depressive symptoms. The mean differences between the baseline and postintervention CES-D scores were compared between the CBT-intervention and control groups. The CES-D score decreased significantly more in the CBT-intervention group than in the control group. The difference in pooled mean differences between the two groups was −4.98. CONCLUSIONS: CBT is an efficient intervention tool for reducing the various emotional burdens experienced by CGPWD. This meta-analysis found that CBT significantly improved the depressive symptoms of CGPWD.

PURPOSE: We report early experiences on endovascular abdominal aortic aneurysm repair (EVAR). METHOD: We reviewed the results of 15 patients underwent EVAR between 2003 and 2007 in the Kyung Hee University Medical Center, retrospectively. RESULT: Mean age of patients was 71.2 years (range, 51~85 years). 14 patients (93.3%) had comorbidities. All of AAAs were infrarenal types. The mean size of AAA was 58.5 mm (38~91 mm), and the mean length, diameter, and angle of neck was 26.4 mm, 19.9 mm, and 37.7degrees, respectively. Ten patients were accompanied with iliac aneurysm. 14 were bifurcated grafts and 1 was straight tubular graft. Mean procedure time was 100.6 minutes. Mean length of hospitalization was 6.5 days (2~10 days). There was no need of transfusion or use of an intensive care unit. Fever of unknown origin occurred in 7 cases but resolved spontaneously. Device deployment was successful in 100% (primary 9 cases, assisted-primary 6 cases). There were seven endoleaks during interventions. One patient with secondary type II endoleak and suprarenal enlargement of AAA sac died from aortoenteric fistula. In one patient with perigraft abscess after EVAR, surgical drainage was performed. Decrease of AAA diameter > or =5 mm in two patients, newly developed suprarenal aortic aneurysm in one patient were detected on CT scan during mean follow-up of 11.4 months (2-29 months) and remained unchanged in other twelve cases. CONCLUSION: These early results suggest that EVAR offers considerable benefits for appropriate patients, but is thought to need more experiences and long-term outcomes.

Cyclooxygenase (COX) is an enzyme involved in the conversion of arachidonic acid to prostaglandins(PGs), and exists in two forms, COX-1 and COX-2. COX has been reported to be involved in early implantation by secretion of PGs which causes permeability of vessels and reaction of decidual cells around the implantation site. Recently, in mice and sheep studies, COX-1 and COX-2 expression in the endometrium has been reported to be different according to implantation and stages of the estrous cycle, but expression of COX-1 and COX-2 in human endometrium during the menstrual cycle has not yet been established. The purpose of this stuffy was to observe the variances of COX-1 and COX-2 expression by immunohistoehemical staining in endometrial samples obtained from human hysterectomy specimens and biopsies of women of reproductive age according to different stages of the menstrual cycle. Also, we attempted to observe COX-1 and COX-2 expression in the epithelial and stromal cells of the endometrium obtained during the mid-secretory phase, which were cultured separately. COX-2 showed a cyclic pattern of expression according to the different stages of the menstrual cycle and was strongly expressed particularly at the mid-secretory phase which corresponds to the time of implantation. However, COX-1 tended to be increased in the early proliferative, and mid- and late secretory phases, but was also expressed in the whole menstrual cycle showing no particular pattern. In the separately cultured cells COX-1 was expressed in epithilial cells and COX-2 in the stromal cells. The above results suggest that since COX-2 is expressed at the same time as implantation and cultured cells display a specific secretory pattern, COX-2 has inductive endocrine enzyme properties and has an important effect on endometrial cells during implantation. Also, COX-2 expression in endometrial cells may be utilized as a useful marker of endometrial maturation.

Heart failure is a major clinical problem in developed countries with about half of heart failure patients exhibiting decreased left ventricular systolic function. The correct identification and prompt treatment of some specific etiologies can reverse heart failure, and recognition of myocardial recovery may avoid long-term therapy. However, the echocardiographic patterns of patients with a variety of etiologies of heart failure are similar, so the selective use of other imaging techniques is necessary for identification of specific etiologies. The role of repeat imaging in monitoring the therapeutic response is controversial, as is the cessation of medical therapy in patients demonstrating recovery.
