Longitudinal Observation of Border Tissue Configuration During Axial Elongation in Childhood

PurposeTo investigate the change of border tissue configuration during axial elongation in childhood.MethodsFifty-four subjects (108 eyes; age range, 29.3–132.5 months) who had undergone a series of swept-source optical coherence tomography scans at intervals of 6 months or longer were classified into stable axial length (AXL) eyes (n = 55; AXL change of ≤0.36 mm) and elongating AXL eyes (n = 53; AXL change of >0.36 mm). The angle between the Bruch''s membrane opening (BMO) reference plane and the border tissue of Elschnig was defined as the border tissue angle (BTA). The border tissue angle, BMO distance (BMOD) and minimum rim width (MRW) were measured in the temporal and nasal regions.ResultsDuring 15.6 ± 7.2 months of follow-up, the AXL significantly increased from 22.8 ± 1.3 mm to 23.3 ± 1.4 mm (P < 0.001). Changes of border tissue angle and AXL showed a significant correlation only in the temporal region of elongating AXL eyes (r = –0.409; P = 0.002), but not in stable AXL eyes. Both BMOD and nasal MRW significantly increased from 1482.5 ± 153.0 to 1506.1 ± 154.6 µm and from 310.6 ± 83.2 to 324.6 ± 95.6 µm, respectively (all Ps < 0.001). The changes of BMOD and nasal MRW showed a significant positive correlation with changes of AXL in elongating AXL eyes but not in stable AXL eyes.ConclusionsDuring the axial elongation in childhood, temporal border tissue configuration change, BMO enlargement, and nasal peripapillary tissue elevation showed a significant correlation with changes in the AXL.

Diagnosis of an accessory spleen mimicking a gastric submucosal tumor using endoscopic ultrasonography-guided fine-needle aspiration

Accessory spleen can be mistaken as a gastric subepithelial mass, and may not be differentiated in CT or endoscopic ultrasonography (EUS). A gastric subepithelial mass was detected on routine endoscopy in a 39-year old woman with history of splenectomy. In subsequent CT and EUS, the subepithelial mass was located on the fourth layer of the stomach. To make a definite diagnosis, EUS-guided fine needle aspiration (FNA) was performed, and a splenic tissue was demonstrated in histologic examination. EUS-guided FNA can be beneficial in the diagnosis of accessory spleen which mimics a gastric subepithelial mass.     

A case of Castleman's disease mimicking a hepatocellular carcinoma: a case report and review of literature

Castleman's disease is a rare disease characterized by lymph node hyperplasia. Although Castleman's disease can occur wherever lymphoid tissue is found, it rarely appears in the abdominal cavity, and is especially rare adjacent to the liver. Here, we report a rare case of Castleman's disease in the portal area that mimicked a hepatocellular carcinoma (HCC) in a chronic hepatitis B patient. A 40 year-old woman with chronic hepatitis B presented with right upper quadrant discomfort. Computed tomography and magnetic resonance imaging results showed a 2.2 cm-sized, exophytic hypervascular mass in the portal area. HCC was suspected. However, histologic examination revealed Castleman's disease. We suggest that Castleman's disease should be included as a rare differential diagnosis of a hypervascular mass in the portal area, even in patients with chronic hepatitis B.     

A case of phlebosclerotic colitis in a hemodialysis patient

Phlebosclerotic colitis is a rare disease of intestinal ischemia caused by calcified peripheral mesenteric veins and a thickened colonic wall, differentiating it from the typical ischemic colitis. A 68-year-old man who was undergoing hemodialysis presented with hematochezia and abdominal pain. Colonoscopic findings showed typical dark purple-colored edematous mucosa. Linear calcifications in the colon were noted on both a plain abdominal radiolography and abdominal computer tomography. These findings suggested that the patient suffered from phlebosclerotic colitis. Following bowel rest and fluid therapy, there was full recovery. We herein report a rare case of phlebosclerotic colitis in a hemodialysis patient and include a review of the relevant literature.     

Guidelines for the management of ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by a relapsing and remitting course. The quality of life can decreases significantly during exacerbations of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies are currently used for the management of UC. However, many challenging issues exist and sometimes these lead to differences in practice between clinicians. Therefore, Inflammatory Bowel Diseases (IBD) Study Group of Korean Association for the Study of Intestinal Diseases (KASID) set out the Korean guidelines for the management of UC. These guidelines are made by the adaptation using several foreign guidelines and encompass treatment of active colitis, maintenance of remission and indication for surgery in UC. The specific recommendations are presented with the quality of evidence. These are the first Korean treatment guidelines for UC and will be revised with new evidences on treatment of UC.
