Korean Journal of Schizophrenia Research 2014;17(1):5-11
The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fifth version (DSM-5) finally introduced in 2013. Psychiatrists and researchers of neuroscience were looking forward that DSM-5 will introduce a new paradigm of diagnostic criteria. However, they have criticized on DSM-5 about not including of neurobiological criteria after DSM-5 published. Since schizophrenia spectrum disorder is heterogeneous and hard to diagnose correctly, we can guess that there might be a big affliction in preparation of DSM-5. Diagnostic criteria of schizophrenia spectrum disorder in DSM-5 changed in several points including changes of Criteria A of schizophrenia. The most outstanding change is the elimination of subtypes of schizophrenia, and introducing of Clinician-Rated Dimensions of Psychosis Symptom Severity for further division into homogenous subgroups depending on psychosis symptoms. Until now, the results of various neurobiological investigations are not consistent, so neurobiological criteria of schizophrenia spectrum disorder deserved no inclusion in DSM-5. Thinking comprehensively, DSM-5 might decide to choose stability rather than challenge. In the future, the diagnostic criteria of schizophrenia spectrum disorder in DSM will progress with inclusion of neurobiological criteria, and researches of schizophrenia spectrum disorder will make advance that match changes in progression of DSM.

Congenital Hyperextension of the Knee is a extremly rare deformity, in which the tibia is displaced anteriorly in relation to the femur. It is usually classified into three subtypes according to severity of the status: genu recurvatum, subluxation and dislocation. (Curtis and Fisher) We experienced a genu recurvatum type of congenital hyperextension of the knee in June, 1976.

PURPOSE: This cross-sectional study was designed to identify anger-expression typesof adolescent women and investigate the relation between the identified anger-expression types and their problem behaviors and health status. METHOD: One hundred ninety nine high school freshmen were recruited from September to November, 2003. Data wasanalyzed using descriptive statistics, cluster analysis, chi-square-test, ANOVA, and Duncan's multiple comparison test. RESULT: Three anger-expression types in adolescent women were found; Anger-out/in, Anger-control/in, and Anger- control type. Adolescent women with frequently using the anger-out/in type and with higher state anger reported more delinquent behaviors, more health risk behaviors, and higher psychosomatic symptoms. However, adolescent women with lower state anger and frequently using the anger-control type reported more depression scores. CONCLUSION: There is a need to further clarify the relationship between anger-expression typesand depression in adolescent women. The findings suggest the necessity of a development of the program for lowering the anger level and controlling the unfavorable anger expression types such as the anger-out in.

BACKGROUND: This study was carried out to evaluate the efficacy of desferrioxamine as a chelating agent in iron overloaded patients with severe aplastic anemia due to multiple transfusion. METHODS AND MATERIALS: From Oct. 1995 to Aug. 1996, 15 patients with aplastic anemia, diagnosed from May 1995 to Jan. 1996 at St. Mary's Hospital, who had a transfusional hemosiderosis were included in this study. They received 19 courses of high-dose desfer-rioxamine therapy for 6 days(20 to 30 mg/kg daily as a 24-hour intravenous infusion) . Before and after treatment, we measured serum ferritin, iron, TIBC, 24-hour urinary excretion of iron. RESULTS: 1) The range of iron load before treatment was between 4.5 and 20.0 gram. 2) Because of limit of detection(1,800 microgram/L), it was difficult to compare the changes of serum ferritin level after therapy to those of before therapy. 3) There was no significant differences between the levels of serum iron before and after therapy(214.3+/-62.8 vs 220.0+/-53.3). And there was no significant differences between TIBC before and after therapy(235.8+/-64.6 vs 259.4+/-60.1). 4) Iron/TIBC ratios were significantly deceased after desferrioxamine treatment compared to those of before therapy(0.90+/-0.04 vs 0.85+/-0.04, P<0.001) and mean urinary excretions of iron were increased by high-dose desferrioxamine compared to those by test dose(6.5+/-7.6 vs 29.1+/-14.3, P<0.001) CONCLUSION: High-dose desferrioxamine therapy is very effective for chelating and excretion of iron in iron overloaded patients with severe aplastic anemia due to multiple transfusion. A repeat administration of desferrioxamine is necessary for the iron overloaded patient to eliminate the risk of a transfusional hemosidersis.

PURPOSE: To analyze the effect of scleral lens application for preventing corneal edema during vitrectomy on postoperative corneal status using anterior segment OCT (RTVue 100, Optovue, Fremont, CA, USA). METHODS: The medical records of 42 eyes (42 patients) who underwent total vitrectomy with no appreciable corneal disease between November 2014 and June 2015 were retrospectively reviewed. Evaluations were performed at 1 day, 1 week, and 1 month after total vitrectomy. Corneal status was noted at every follow-up visit using anterior segment OCT. An analysis was performed to define the changes in corneal status in association with scleral lens application during the surgery. RESULTS: 18 of 42 eyes were treated with a scleral lens during total vitrectomy. The corneal thickness increased after vitrectomy in all cases. The mean corneal thickness increment was 23.9 ± 9.7 µm in the scleral lens group and 43.0 ± 19.5 µm in the non-scleral lens group at 1 day after vitrectomy (p < 0.001). At 1 week after vitrectomy, the mean corneal thickness increment was 8.1 ± 7.2 µm in the scleral lens group and 32.3 ± 19.2 µm in the non-scleral lens group (p < 0.001). The difference in superficial punctate keratitis grade between the two groups was not statistically significant. CONCLUSION: Scleral lens application during vitrectomy seems to prevent postoperative corneal edema. More cases and a longer period of study is needed to draw definitive conclusions.

PURPOSE: Tacrolimus (FK506) is a new potent immunosuppressive agent which has been used as a primary immunosuppressive agent and rescue therapy for refractory rejection in kidney transplantation. In vitro, on a molecular basis, tacrolimus is 10 to 100 times more potent than cyclosporine. Complications associated with tacrolimus are similar to those seen in cyclosporine, including nephrotoxicity. An early marker of tacrolimus-induced nephropathy is tubular vacuolization, whereas long-term administration of tacrolimus is associated with striped interstitial fibrosis and arteriolar hyalinosis. However, morphological changes and pathogenesis of fibrosis in chronic tacrolimus-induced nephropathy remain poorly understood. Transforming growth factor (TGF)-beta1 has been implicated in the fibrosis of a number of chronic diseases of the kidney and other organs. This study was designed to clarify the ultrastructural changes of tacrolimus-induced nephropathy, and to evaluate the relationship between tacrolimus- induced nephropathy and expression of TGF-beta1. METHODS: Male ICR mice received tacrolimus daily at a dose of 2.5 mg/kg by intraperitoneal route for 12 weeks and sacrified 1, 4, 8, 10, and 12 weeks after the initiation of the study, respectively. The kidneys were removed, the cortex is carefully dissected from the medulla, and the tissues are processed for evaluation by light microscopy, electron microscopy, immunohistochemistry and RT-PCR for RNA analysis. RESULTS: Characteristic histological changes of tacrolimus-induced nephropathy were peritubular capillary and intraglomerular capillary congestions, vacuolizations of the tubular epithelium, pericapillary focal fibrosis, and tubular atrophy. Tacrolimus- treated kidneys had a progressive increase in the expression of TGF-beta1, especially in the glomerular and interstitial capillary endothelial cells and atrophied tubular epithelial cells. TGF-beta1 mRNA is expressed persistently in tacrolimus- treated mice for 12 weeks. CONCLUSION: It can be concluded that TGF-beta1 may be involved in the fibrogenesis in the tacrolimus-induced nephropathy.
