Assessment of Post-Stroke Cognitive Dysfunction Using 3-Dimensional Virtual Reality Program

OBJECTIVE: To test the feasibility of newly developed 3- dimensional virtual reality (VR) program for assessing the post-stroke cognitive dysfunction. METHOD: Thirty five post-stroke patients and twenty normal healthy subjects were recruited in this study, and post-stroke patients were classified into three groups according to the severity of cognitive dysfunction. We developed three dimensional virtual reality program to assess the cognitive function with virtual subway environment from taking a subway to arriving at one's destination. The total score, number of success and cue were obtained during completing virtual tasks. We investigated the test-retest reliability, and the parameters of the 3-dimensional VR program were compared with Korean Mini-mental status examination. RESULTS: All parameters of the VR program were significantly correlated with MMSE score (p<0.01), and showed the significant difference between patient subgroups and control group (p<0.05). The test-retest reliability of the VR program was significantly high (p<0.01). CONCLUSION: Three dimensional virtual reality program may be helpful to assess the cognitive function in patients with stroke.

Two Cases of Fitz - Hugh - Curtis Syndrome Associated with Ectopic Pregnancy / 대한산부인과학회잡지

Fitz-Hugh-Curtis syndrome is a condition in which, as a result of pelvic inflammatory disease, the liver capsule becomes involved with inflammatory exudate that later leaves violin string adhesions. Although in the past Neisseria gonorrhea was thought to be the only etiological agent, recent data indicate that Chlamydia trachomatis may play an important role in perihepatitis. Perihepatic adhesions may be an aftereffect of the acute hepatic episode, and because the cause of ectopic pregnancy is thought to be salpingitis, women with an ectopic pregnancy may have a higher prevalence of coexisting perihepatic adhesion. The incidence of this conditon in ectopic gestation was reported to be 14-34 %. Direct observation of the liver and pelvis through laparoscope is the most definitive method of diagnosing salpingitis and perihepatitis. Standard treatement regimens recommended for salpingitis are adequate also for treatement of perihepatitis. We have experienced two cases of Fitz-Hugh-Curtis syndrome associated with ectopic pregnancy, and report with the brief review of the literatures.
