ABSTRACT
Intussusception is a rare disease in adults. A demonstrable etiology is found in approximately 85% of all cases, and approximately 40% of them are caused by malignant tumors. A 65-year-old patient visited the outpatient department with mild abdominal pain without other symptoms. The initial laboratory test and simple X-ray showed normal findings. CT revealed intussusception in the ileocecal area. The initial colonoscopic biopsy revealed atypical cells. Follow up colonoscopy showed spontaneous reduction of the intussusception. Diffuse large B-cell lymphoma was suspected in the second colonoscopic biopsy. An elective operation was performed. This case reports a case of a spontaneous reduction of adult intussusception with a brief review of literature.

Aberrant right subclavian artery (ARSA) is a rare congenital anomaly but is the most common of the congenital vascular anomalies of the aortic arch. We report the case of a 68-year-old female undergoing chemotherapy for multiple myeloma who had a large thoracic aortic aneurysm (7.4 cm) with ARSA. She was treated with a hybrid procedure that combined a left common carotid-to-subclavian artery bypass with a "thoracic endovascular aortic repair (TEVAR)" because of the risk associated with a thoracotomy. A stent graft was deployed in the proximal part of the descending aorta to cover the thoracic aortic aneurysm after a left common carotid-to-subclavian bypass was made to restore blood flow in the left arm. There was no endoleak on digital subtraction angiography. Hybrid therapy can be performed successfully for the treatment of thoracic aortic aneurysm with ARSA.

Acute aortic dissection with malperfusion syndrome is associated with poor clinical outcomes, and surgical treatment for complicated descending aortic dissections is associated with a high risk of operative mortality. Endovascular repair is emerging as a good alternative to surgery. Endovascular repair for a descending aortic dissection with malperfusion syndrome offers good clinical outcomes because of technical and anatomical benefits. Here, we report a case of descending aortic dissection and malperfusion syndrome in the left common iliac artery that was successfully treated with an aortic stent graft and peripheral stent.

Behcet's disease shows systemic involvement, including mucocutaneus, ophthalmical, neurological, pulmonary, gastrointestinal, urogenital, mucoskeletal, and cardiovascular disorders. Aneurysmal changes develop in 65% of patients with arterial involvement and are associated with a poor prognosis. Although many attempts have been made to surgically manage these serious arterial lesions, several reports have shown a high recurrence rate and operation-related complications. Stent-graft placement has been indicated for the treatment of pseudoaneurysms and aneurysms in patients with a high surgical risk, including those with Behcet's disease. We herein describe an abdominal aortic pseudoaneurysm in a patient with Behcet's disease that was successfully treated with stent-graft insertion without an endoleak after 36 months of follow-up.

Treatments for patient with ankylosing spondylitis (AS) include non-steroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs) and anti-tumor necrosis factor-alpha (TNFalpha) agents. However, owing to the well-known nephrotoxicity of NSAIDs and some DMARDs, the use of these drugs is limited in AS patients with renal insufficiency. As the pharmacokinetics and metabolism of anti-TNFalpha agents in patients of end stage renal disease, especially those receiving peritoneal dialysis (PD), have not been investigated well, little is known about treating them with anti-TNFalpha agents. We described the safety and efficacy of etanercept, a soluble fusion protein comprising the TNF receptor 2 in linkage with the Fc portion of immunoglobulin G, in a 40-year-old male AS patient receiving PD.

Intestinal metaplasia of the stomach is a common metaplastic lesion associated with chronic gastritis and mucosal atrophy. However, squamous metaplasia is a comparatively rare condition. On endoscopy, squamous metaplasia is usually observed as a whitish mucosal lesion in the lesser curvature of the cardiac region of the stomach. When Lugol's iodine solution is applied, the lesion stains brown in the same way as normal esophageal mucosa. We report a case of 79-year-old man with a whitish flat lesion in the lesser curvature of the cardiac region on surveillance endoscopy after endoscopic treatment of gastric adenoma. The endoscopic biopsy showed stratified squamous epithelial mucosa.

Single nucleotide polymorphisms (SNPs) are the most abundant forms of human genetic variations and resources for mapping complex genetic traits and disease association studies. We have constructed a linkage disequilibrium(LD) map of chromosome 22 in Korean samples and compared it with those of other populations, including Yorubans in Ibadan, Nigeria (YRI), Centred'Etude du Polymorphisme Humain (CEPH) reference families (CEU), Japanese in Tokyo (JPT) and Han Chinese in Beijing (CHB) in the HapMap database. We genotyped 4681 of 111,448 publicly available SNPs in 90 unrelated Koreans. Among genotyped SNPs, 4167 were polymorphic. Three hundred and five LD blocks were constructed to make up 18.6% (6.4 of 34.5 Mb) of chromosome 22 with 757 tagSNPs and 815 haplotypes(frequency > or = 5.0%). Of 3430 common SNPs genotyped in all five populations, 514 were monomorphic in Koreans. The CHB + JPT samples have more than a 72% overlap with the monomorphic SNPs in Koreans, while the CEU + YRI samples have less than a 38% overlap. The patterns of hot spots and LD blocks were dispersed throughout chromosome 22, with some common blocks among populations, highly concordant between the three Asian samples. Analysis of the distribution of chimpanzee-derived allele frequency (DAF), a measure of genetic differentiation, Fst levels, and allele frequency difference (AFD) among Koreans and the HapMap samples showed a strong correlation between the Asians, while the CEU and YRI samples showed a very weak correlation with Korean samples. Relative distance as a quantitative measurement based upon DAF, Fst, and AFD indicated that all three Asian samples are very proximate, while CEU and YRI are significantly remote from the Asian samples. Comparative genome-wide LD studies provide useful information on the association studies of complex diseases.
