OBJECTIVES: There have been several evidences that the central nervous system defect is one of the etiologic factors in schizophrenia and high nailfold plexus visibility can reflect indirectly. These are particularly related to the negative symptoms of schizophrenia. In this study, we examined the relationship between nailfold plexus visibility and various clinical variables in schizophrenia. METHODS: Forty patients(20 males, 20 females) satisfying the DSM-IV criteria for schizophrenia and forty normal controls(20 males, 20 females) were measured for Plexus Visualization Score(PVS) by using capillary microscopic examination. We used Positive and negative Syndrome Scale(PANSS). Uimann-Giovannoni Process-Reactive Questionnaire(PRQ), Phillips Premorbid Adjustment Scale(PAS). Continuous Performance Test, and Backward Masking for psychopathology and clinical variables. RESULTS: There was no significant relationship between schizophrenic subjects and normal controls in PVS. PVS was correlated with PANSS positively except negative symptom subscore. PVS was correlated with PRQ score negatively, and with PAS score positively. CONCLUSIONS: This study shows high PVS are associated with more severe psychotic symptoms and with clinical variables, such as disease process and premorbid adjustment, in some schizophrenics.

OBJECTIVE: There have been several evidences that the central nervous system deflect is one of the etiologic factor in schizophrenia and minor physical anomalies can reflect these deflects indirectly. These central nervous deflects are particularly related to the negative symptoms of schizophrenia. In this study, we examined the relationship between minor physical anomalies and psychopathology in schizophrenia. METHODS: Forty-four patients(22 males, 22 females) satisfying the DSM-IV criteria for schizophrenia were measured for minor physical anomalies by using Waldrop Anomaly Scale(WS) and we used Positive and Negative Syndrome Scale(PANSS), Ulmann-Giovannoni Process-Reactive Questionnaire(PRQ), and Phillips Premorbid Adjustment Scale(PAS) for evaluating psychopathology and clinical variables. RESULTS: Schizophrenic patients had a higher group mean WS score than that found in the control group. Score of WS was correlated with PANSS and PAS score positively, and with PRQ score negatively. CONCLUSION: This study shows minor physical anomalies are associated with clinical variables with regard to symptom severity, poor premorbid adjustment and process of illness in at least some schizophrenics.
