After publishing 2001 version of the Korean Medication Algorithm for Schizophrenia, the strategy of pharmacologic treatment for schizophrenia has been altered with the rapid advancement in the area of psychopharmacology. Currently, the feasibility of this algorithm has been evaluated. Guidelines require updating when significant new evidence appears. Recently, several guidelines of the treatment of schizophrenia including the APA practice guideline, the Expert Consensus Guideline Series and the Texas Medication Algorithm Project (TMAP) Antipsychotic Algorithm for Schizophrenia were revised. In this review, the authors briefly discussed the problems and limitations of the Korean Medication Algorithm for Schizophrenia and presented the direction of future revision on the model of above-mentioned guidelines.

Hyponatremia is frequently seen in intracranial hemorrhagic patients and has been often attributed to inappropriate secretion of antidiuretic hormone. But in recent years, a number of studies have shown that hyponatremia in many patients with intracranial disease may actually be caused by cerebral salt wasting (CSW) syndrome and circulating Atrial natriuretic peptide (ANP) and Brain natriuretic peptide (BNP) are probably involved. This report describes a patient who developed bacterial meningites caused by pseudomonas aeruginosa and CSW syndrome after removal of pituitary adenoma. CSW syndrome resolved by fluid and salt replacement after 4 months.

STUDY DESIGN: Retrospective study. OBJECTIVES: To identify clinical features and risk factors helpful for the prevention and early diagnosis of neurological complications. OVERVIEW OF LITERATURE: Previous studies have investigated postoperative complications only for specific disease entities and did not present distinctive clinical features. MATERIALS AND METHODS: This was an observational study of patients who underwent posterior thoracolumbar spinal surgery in the orthopedic department of a single hospital over the course of 19 years (1995-2013). The incidence, cause, onset time, and risk factors of complications were investigated. Neurological deterioration was graded on a 5-point numeric scale: G1, increased leg pain or sensory loss, G2, unilateral motor weakness; G3, bilateral motor weakness; G4, cauda equina syndrome; and G5, complete paraplegia. RESULTS: Sixty-five cases out of 6574 (0.989%) developed neurological complications due to the following causes: epidural hematoma, 0.380%; instrumentation with inadequate decompression, 0.213%; mechanical injury, 0.167%; inadequate discectomy, 0.061%; and unknown cause, 0.167% (p=0.000). The grade of neurological deterioration was G1 in 0.167% of patients, G2 in 0.517%, G3 in 0.228%, G4 in 0.046%, and G5 in 0.030%. Neurological deterioration was most severe in patients who experienced epidural hematoma, followed by those in whom complications occurred due to instrumentation with inadequate decompression, unknown causes, mechanical injury, and inadequate discectomy, in order (p=0.009). Revision surgery was a significant risk factor (p=0.000; odds ratio, 2.741). The time that elapsed until symptom development was as follows, in order: unknown cause, 0.6 hours; epidural hematoma, 5.4 hours; mechanical injury, 6.6 hours; inadequate discectomy, 18.0 hours; and instrumentation with insufficient decompression, 36.0 hours (p=0.001). CONCLUSIONS: The incidence of neurological complications in our cohort was 1%. Revision surgery increased the risk by 3 times. Severe cases (cauda equina syndrome or complete paraplegia) rarely developed, occurring in 0.08% of patients. The major causes of neurological decline were epidural hematoma and instrumentation with inadequate decompression. Close observation in the early period was important for the diagnosis because most patients developed symptoms within 12 hours. Delayed diagnosis was most common in complications caused by instrumentation with inadequate decompression.

PURPOSE: A relationship between Febrile seizure (FS) and iron deficiency anemia (IDA) has been found in several studies. However, few studies have focused on the role of IDA in complex febrile seizures (CFS) and simple febrile seizures (SFS) and there is no report on whether IDA is a risk factor for recurrence. The aim of this study was to investigate the role of IDA in SFS and CFS and to examine the effect of IDA on recurrence. METHODS: Patients (n=166) who had been diagnosed with FS were enrolled in our study. Subjects were divided into the following groups for analysis: the SFS and CFS groups, recurrence and non-recurrence groups. The onset age was compared in each group of patients and laboratory test results based on IDA were compared. RESULTS: Between the SFS and the CFS groups, there was no significant difference in laboratory test results based on IDA. There was a significant difference in onset age between the two groups and the onset age tended to be lower in the CFS group (24.00 vs. 16.49 months) (P=0.004). Comparing recurrence and non-recurrence groups, the mean corpuscular volume was significantly different (P=0.043) with the recurrence group having a lower mean corpuscular volume level (78.92 vs. 77.48). The onset age in the recurrence group was lower (26.02 vs. 19.68 months). CONCLUSION: This study suggests that onset age could be a risk factor for CFS, and IDA may not contribute to elevating the risk of CFS. However, IDA may play an important role in the recurrence of FS.

Purpose: To evaluate the accuracy of MRI in predicting the pathological complete response (pCR) and the residual tumor size of breast cancer after neoadjucant chemotherapy (NAC), and to determine the factors affecting the accuarcy. Materials and Methods: Eighty-eight breast cancer patients who underwent surgery after NAC at our center between 2010 and 2017 were included in this study. pCR was defined as the absence of invasive cancer on pathological evaluation. The maximum diameter of the residual tumor on post-NAC MRI was compared with the tumor size of the surgical specimen measured pathologically. Statistical analysis was performed to elucidate the factors affecting pCR and the residual tumor size-discrepancy between the MRI and the pathological measurements. Results: The pCR rate was 10%. The diagnostic accuracy of MRI and the area under the curve for predicting pCR were 90.91% and 0.8017, respectively. The residual tumor sizes obtained using MRI and pathological measurements showed a strong correlation (r = 0.9, p < 0.001), especially in patients with a single mass lesion (p = 0.047). The size discrepancy between MRI and the pathological measurements was significantly greater in patients with the luminal type (p = 0.023) and multifocal tumorson-mass enhancement on pre-NAC MRI (p = 0.047). Conclusion MRI is an accurate tool for evaluating pCR and residual tumor size in breast cancer patients who receive NAC. Tumor subtype and initial MRI features affect the accuracy of MRI.

Objective: The Block Design Test (BDT) is known to be an effective measure in diagnosing age-related cognitive decline of visuospatial function. The goal of this study is to investigate the effects of age, education years, and gender on the performance of the BDT and to provide normative data in Korean community-dwelling participants who are 55 to 90 years old. Methods: The participants were 432 non-demented adults aging from 55 to 90 years old. The BDT was administered to participants according to its manual. Multiple linear regressions and analyses of variance were conducted, including age, gender, and educations were used as covariates. Results: Age, educational years, and gender were found to be significantly associated with performance on the BDT. As age increased, BDT performance decreased. Educational years were associated with BDT performance. Men showed higher performance (29.9±10.3) compare to women (26.1±8.7). The BDT is influenced by age, educational years, and gender. Conclusion Unlike the previous study, the current study shows that gender has a significant influence in visuospatial ability in the old population. Present normative data will be useful for clinicians in evaluating aging participants with cognitive impairment.
