1.Neuropsychological Evaluation of Visual Perception and Construction.
Journal of the Korean Society of Biological Psychiatry 1997;4(1):24-28
Visual perception is a complex process engaging many different aspects of brain functioning. Like other cognitive functions, the extensive cortical distribution and complexity of visual perceptional activities make them highly vulnerable to brain injury. Dectection and characterization of perceptual require careful assessment as well as the application of selected neuropsychological tests. In the article we reviewed neuropsychological assessment of visual perception and constructional abilities. And the principal visuospatial disorders are discussed, the associated neuropsychiatric disorders are presented.

PURPOSE: The purpose of this study was to evaluate the usefulness of CT-guided percutaneous needle aspiration(PCNA) of paraaortic and pelvic lymph nodes in patients with uterine cervical carcinoma. MATERIALS AND METHODS: CT-guided PCNA was performed in 18 patients with treated cervical carcinoma. initial clinical stages were CIS in one, lb in three, lib in ten, and IIIb in four cases. We used 20 gauge Westcott needles for aspiration. Mean depth from skin to lymph nodes was 10.0cm in paraaortic group (n=13) and was 7.9cm in pelvic group (n=5). The size of lymph nodes ranged 1.0-3.0cm (mean :1.8) and 1.5-5.0cm (mean :2.6cm), respectively. RESULTS: All cases with paraaortic lymph node enlargement were proved to be metastatic lymphadenopathy. In five cases with pelvic lymph node enlargement, three were proved to be malignancy and two were negative. Among 16 cases with metastatic lymphadenopathy, eight patients were treated with chemotherapy, five with radiation therapy, and three with chemotherapy and radiotherapy. In two cases with negative results lymph nodes were disappeared or unchanged on follow up CT scans. No complications were encountered during CT-guided PCNA procedure. CONCLUSION: CT-guided PCNA of paraaortic and pelvic lymph nodes is a useful method in determining metastasis from cervical carcinoma and in planning further treatment.

Neuroleptic malignant syndrome is a rare, but potentially life-threatening adverse event associated with the use of neuroleptic agents. We describe the case of a 47-year-old schizophrenic woman who was treated with clozapine for years. The patient developed acute renal failure with pulmonary edema, and underwent mechanical ventilation and hemodialysis.

Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

Almost all advanced glomerular diseases have glomerular sclerotic changes to varying degrees whatever causes their primary glomerular disease are. Pathogenesis of these sclerosis has been thought of as the hyperfiltration in the primary glomerulosclerosis due to development of glomerular hypertension in each insulted glomeruli. This background gave the theoretical bases for antihypertensive therapies for supporting chronic renal insufficient patients. Angiotensin converting enzyme (ACE) inhibitor, one of the antihypertensive drugs, has received attention recently for its effectiveness. The aims of this study determined the effects and mechanism of the ACE inhibitor, enalapril, on the glomerulosclerosis in FGS/NgaKist mice, which was an animal model of chronic renal failure by generating spontaneously heavy proteinuria and progressive glomerulosclerosis. Five-week-old FGS/NgaKist mice (n=38) were assigned to four groups. Group 1a (n=6) and group 2a (n=8) fed with a vehicle, were sacrificed at the end of 10 weeks and 15 weeks, respectively. Group 1b (n=12) and 2b (n=12) received enalapril (100 mg/L) in drinking water for 5 weeks and 10 weeks from 6th week of age respectively, and were sacrified on the same day as the control groups. Doses of enanapril were maintained to 2 mg/kg/day by measuring the amount of water consumption. In enalapril groups 1b and 2b, systemic blood pressure (74.7 14.0 mm Hg, 74.3 15.9 mmHg) were significantly lower than control group 2a (116.1 4.6 mmHg, P<0.001). Similarly, degree of proteinuria lowered in enalapril group 2b versus control group 2a (0% and 50.0%, P<0.001). Glomerulosclerosis percentage significantly decreased (P<0.001) (group 1b and 2b; 1.9 6.5, 5.6 7.0 vs control 1a and 2a; 32.8 15.5, 31.4 13.8). Glomerulosclerosis score also decreased (P<0.001) (group 1b and 2b; 0.02 0.08 vs control 1a and 2a; 0.48 0.12, 0.30 0.14). The immunofluorescent staining of enalapril groups showed negative for mesangial deposition of IgG, IgA, IgM, and C3 which were positive in control groups. Immunohistochemical staining with TGF-beta1 was negative in enalapril groups and sclerotic glomeruli both enalapril groups and control groups. These results support that the ACE inhibitor has a renoprotective effect on glomerulosclerosis not only by decreasing the blood pressure but also by suppressing the immune deposits on glomeruli.

Congenital lobar emphysema has the clinical features of an air block' syndrome with- out the evidence of pulmonary infection or intrabronchial foreign body. The hyperinflated lung causes a compression of uninvolved lobes creating respiratory distress, cyanosis within the first weeks of life. We experienced a case of congenital lobar emphysema diagnosed incidentally by chest reontgenogram in an infant with frequent upper respiratory infection within a few weeks of life. Chest X-ray revealed extensive emphysematous changes in the left upper lobe, shifting of heart and medistinum to the right and compression of the right lung. Respiratory distress, cyanosis and chest wall retraction ensued and left upper lobe Lobectomy was performed successfully.
