Background: The purpose of this study was to examine the causes and pathologic process of chronic non-productive cough as an isolated symptom with a normal spirometry and chest radiograph by investigating clinicopathologic findings. Method: We studied 25 adults with chronic non-productive cough over a 3-week period with a normal chest radiograph and pulmonary function tests without any other symptoms. Clinical assessment, cough score, chest and sinus radiograph, pulmonary function tests, methacholine challenge, allergic skin prick test, and bronchoscopy for bronchial biopsies were performed. Subjects were then treated with prednesolone 20 to 30 mg/day for 1 to 2 weeks. Results: The experimental group was divided into two subgroups-those infiltrated with eosinophils, and those infiltrated with lymphocytes depending on eosinophil and lymphocyte counts, both of which were respectively higher than those of the control group. Eosinophils infiltrated group had mean numbers of eosinophil of 89.8 $cells/mm^3$ while control group's mean was 0.4 $cells/mm^2$(p=0.005). Lymphocyte infiltrated group was 4 patients whose mean was 84.3 $cells/mm^2$ with 28.4 $cells/mm^2$ of control group(P=0.026). In addition, the mean thickness of the basement membrane of experimental group was $14.20{\pm}5.20{\mu}m$ in contrast of control group whose mean was $3.50{\pm}1.37{\mu}m$(P=0.001). With the methacholine challenge test, 7 of the 21 eosinophil infiltrated subjects were diagnosed with cough variant asthma ; the other 14 with eosinophilic bronchitis. Three subjects with eosinophilic bronchitis were atopic positive (21.4%) with the skin prick test In the lymphocyte dominant group, all four subjects were diagnosed with lymphocytic bronchitis. Cough score was improved after steroid treatment in 22 of 25 subjects in the experimental group (88.0%). Conclusion: These results suggest chronic non-productive cough as an isolated symptom with a normal spirometry and chest radiograph was associated with airway inflammation by eosinophil and lymphocyte infiltration. The causes for chronic non-productive cough were eosinophilic bronchitis, cough variant asthma, and lymphocytic bronchitis(written in frequency). They further suggest that therapeutic treatment with steroids can provide effective symptomatic relief.
Objectives : The purpose of this study is to evaluate the role of structural and functional changes of the brain in the pathophysiology of schizophrenia. Methods : The authors measured the regions of interest on the magnetic resonance imaging of the brain in 20 patients with paranoid schizophrenia(15 men and 5 women) and 23 control subjects(15 men and 8 women). We also assessed the neurocognitive functions with the Wisconsin Card Sorting Test, the Benton Neuropsychological Assessment, and the Weschler IQ test-Korean version, soft neurologic signs, and psychiatric symptoms in the patient group. Results : In the patient group, all ventricles and basal ganglia including caudate nucleus and globus pallidus were significantly enlarged. Although there were no significant differences between the two groups in the values of right frontal lobe and left temporal lobe, there was a tendency of decrease in the values of right frontal lobe and left temporal lobe. There were significant positive correlations between the values of ventricles and the frequency of previous hospitalization. However, there were no significant correlations between other values of regions of interest and clinical data. The value of the right frontal lobe was significantly correlated with the score of soft neurologic signs, which is suggestive of the neurodevelopmental abnormalities. There were significant correlations between the value of frontal lobe and the scores of the various subscales of Benton Neuropsychiatric Inventory. In contrast, the value of left amygdala and putamen showed significant correlation with the score of verbal IQ on the Weschler IQ test. Structural changes of the temporal lobe areas were related with the positive and general symptom scores on PANSS, while those of the basal ganglia were related with the negative symptom scores. Conclusions : These results suggest that the structural changes of the brain in the patients with schizophrenia show the dual process, which is suggestive that the enlarged ventricle show the neurodegenerative process, while enlarged basal ganglia, and shrinked right frontal and left temporal lobe show the neurodevelopmental abnormalities. Among these changes, structural changes of the frontal lobe related with various neuropsychological deficits, while those of left temporal lobe related with language abnormality. Relative to the relation between structural changes and psychiatric symptoms, structural changes of the temporal lobe areas were related with the positive and general symptoms, while those of the basal ganglia were related with the negative symptoms.
Purpose: Functional imaging of dopamine transporter (DAT) defines integrity of the dopaminergic system, and DAT is the target site of drugs of abuse such as cocaine and methamphetamine. Functional imaging the DAT may be a sensitive and selective indicator of neurotoxic change by the drug. The aim of the present study is to evaluate the clinical implications of qualitative/quantitative analyses of dopamine transporter imaging in methamphetamine abusers. Materials and Methods: Six detoxified methamphetamine abusers (abuser group) and 4 volunteers (control group) were enrolled in this study. Brain MRI was performed in all of abuser group. Abuser group underwent psychiatric and depression assessment using brief psychiatric rating scale (BPRS) and Hamilton depression rating scale (HAMD), respectively. All of the subjects underwent I-123 IPT SPECT (IPT SPECT). IPT SPECT image was analysed with visual qualitative method and quantitative method using basal ganglia dopamine transporter (DAT) specific/non-specific binding ratio (SBR). Comparison of DAT SBR between abuser and control groups was performed. We also performed correlation tests between psychiatric and depression assessment results and DAT SBR in abuser group. Results: All of abuser group showed normal MRI finding, but had residual psychiatric and depressive symptoms, and psychiatric and depressive symptom scores were exactly correlated (r=1.0, p=0.005) each other. Five of them showed abnormal finding on qualitative visual I-123 IPT SPECT Abuser group had lower basal ganglia DAT SBR than that of control ($2.38{\pm}0.20\;vs\;3.04{\pm}0.27$, p=0.000). Psychiatric and depressive symptoms were negatively well correlated with basal ganglia DAT SBR (r=-0.908, p=0.012, r=-0.924, p=0.009). Conclusion: These results suggest that dopamine transporter imaging using I-123 IPT SPECT may be used to evaluate dopaminergic system of the basal ganglia and the clinical status in methamphetamine abusers.
Objective : This study was tried to investigate the specific relationships among cognitve function, neurbehavioral symptoms, and daily living functions, as well as provide the guidline of more proper clinical approches for patients with subcortical cerebrovascular disease. Objects and Methods Subjects were 85 patients whose diagnosis was confirmed by brain CT or MRI and controls were 195 normal persons matched by educational level with the subjects. The cognitive functions were evaluated by BNA(Benton neuropsychiatric assessment), subjective neurobehavioral symptoms by SCL-90-R(Sympton Check List-90-Revised), objective neurobehavioral symptoms by NRS(Neurobehavioral Rating Scale), and daily living function symptoms by NRS(Neurobehavioral Rating Scale), and daily living function by GERRI(Geriatric Evaluation by Relative's Rating Instrument) and IADL(Instrumental Activities of Daily Living Scale). Results: 1) Subjects showed significantly lower cognitive functions than controls in all tests of BNA except Lt-Rt Orientation Test(p=0.09) and facial Recognition Test(p=0.186). 2) In subjective neurobehavioral symptoms, subjects showed significantly lower scores in all symptoms except anxiety(p=0.059), hostility(p=0.159), and phobic anxiety(p=0.849). But in objects neurobehavioral symptoms, subjects showed significantly higher in scores in psychoticism (p=0.000) and neuroticism(p=0.025) of NRS. 3) The score of social functioning of GERRI(p=0.000) and that of IADL(p=0.000) were significantly higher in subjects than in controls. 4) for correlation between cognitive and daily living functions, there were significant correlations between the scores of all items on BNA and the score of cognitive or social function of GERRI and the socre of MDL in corntrols, whereas in subjects, there were significant correlations only between the scores of BNA and the score of IADL. 5) for correlation between neuroehavioral symptoms and daily living functions, there were significant correlatons between the socre of subjective neurobehavioral symptoms and the scores of all subscales of GERRI and the score of MDL in controls. On the contrary, in subjects, there were significant correlations between the score of social function of GERRI and the score of objective neurobehavioral symptoms such as psychoticism, agitiation-hostility, and decrease d motivation-emotional withdrawl. Conclusion : Above results suggest that disturbances in specific function of brain may play a role as a predictor of impairments with specific daily living functions and also suggest that specific correlations among various functions may be useful as clinical parameters for setting of the treatment goal and for assessing the ongoing process in the treatment and rehavilitation of the patients with subcortical cerebrovascular disease.
Objectives:High nailfold plexus visibility can reflect central nervous system defects as an etiologic factor of schizophrenia indirectly. Previous studies suggest that this visibility is particularly related to the negative symptoms of schizophrenia and frontal lobe deficiency. In this study, we examined the relationships between nailfold plexus visibility, and various clinical variables and neuropsychological functions in schizo-phrenic patients. Methods:Forty patients(21males, 19 females) satisfying the DSM-IV criteria for schizophrenia and thirty eight normal controls(20 males, 18 females) were measured for Plexus Visualization Score(PVS) by using the capillary microscopic examination. For the assessment of psychopathology, process-reactivity, premorbid adjustment, and neuropsychological functions, we used Positive and Negative Syndrome Scale(PANSS), Ullmann-Giovannoni Process-Reactive Questionnaire(PRQ), Phillips Premorbid Adjustment Scale(PAS), Korean Wechsler Adult Intelligence Scale(KWIS), Continuous Performance Test(CPT), Wisconsin Card Sort Test (WCST), and Word Fluency Test. We also collected data about clinical variables. Results:PVS was correlated with PANSS positive symptom score and composite score negatively. There were no correlations between PVS and PRQ score, PAS score and neuropsychological variables respectively. Conclusions:This study showed that nailfold plexus visibility was a characteristic feature in some schizophrenic patients, and that higher plexus visibility was associated with the negative symptoms of schizophrenia. There was no association between plexus visibility and neuropsychological functions.
Purpose: To analyze the clinical result of the arthroscopic reduction and fixation for the displaced tibial spine fractures in children and report the utility of the arthroscopic treatment with the review of the literature. Methods: Between December 2000 and July 2004, five patients (average age 9.1 years) received an arthroscopic reduction and fixation of displaced tibial spine fracture. A male-to-female ratio was 3:2 and mean follow-up was 38.2$(13{\sim}56)$ months. All five patients were classified type III by Movers and McKeever classification. The average period from injury to operation was 4.8 days $(3{\sim}8days)$, the avulsed fragment was reduced by operative arthroscopy and fixated by pull-out suture in 3 patients and by cannulated screw in 2 patients. Postoperatively long leg cast was applied for 2 weeks, and then gradual range-of-motion exercise was permitted. Full weight-bearing ambulation was permitted after 6 weeks. The clinical evaluation was performed by range of motion, Lachman and pivot shift test, KT-1000 arthrometer, Lysholm knee score and the modified Feagin score. Results: All five patients had no symptom and recovered full range of motion of the affected knees. Lachman test was positive finding of 1+ laxity in one patient, the others were negative, and all patients were negative findings for pivot shift test. The result of KT-1000 arthrometric assessment is mean maximum side-to-side differences 1.9 mm. Average Lysholm knee score was 99.4. All patients had excellent results in modified Feagin score. Conclusion: Arthroscopic reduction and fixation of displaced tibial spine fracture in children showed excellent result without complication. Both pull-out suture fixation and cannulated fixation provide an effective treatment option for fixation of the displaced anterior tibial spine fracture.

Purpose : To assess the functional change of salivary gland, recovery of salivary destruction, difference of susceptibility to irradiation between the parotid and sub-mandibular gland, correlation between the xerostomia and excretory rate by irradiation in salivary scan using $^{99m}Tc$-pertechnetate in patients with head and neck cancer. Materials and Methods : We evaluated 19 patients with head and neck cancer who had taken $^{99m}Tc$-pertechnetate salivary gland scan before, during and after radiotherapy. We measured the uptake of radioactivity every 5 minutes for 60 minutes after injection of $^{99m}Tc$-pertechnetate(370MBq). We also evaluated the first excretory function stimulated by 5% citric acid at 30 minutes after injection of $^{99m}Tc$-pertechnetate and then the second excretory function stimulated by 10% citric acid at 45 minutes. Results : The mean uptake curves showed a sharp increase at the 1st week of radiotherapy and then showed a gradual decrease afterwards during radiotherapy. And the mean uptake curves after radiotherapy Persistently decreased on follow up scans without being recovered. The excretory rates decreased gradually as radiation dose increased and were not recovered after radiotherapy. Our study was not satisfactory enough to show the difference of susceptibility to irradiation between the parotid and salivary gland and the correlation between the symptom of xerostomia and the change of the excretory rates. Conclusion : The parotid and submandibular gland scans using $^{99m}Tc$-pertechnetate are useful in the assessment of the functional change of the salivary gland by radiotherapy and predicted the functional change of the salivary gland until 1 year-follow up scan.

Objectives : The craniopharyngioma is a benign tumor located at least in part in the suprasellar cistern. However, the symptoms and signs from this tumor may be determined not only by the location of the tumor but also by its size and the age of the patient. The objective of our study is to analyze retrospectively the clinical manifestations of craniopharyngiomas with regards to tumor characteristics in children and adults. Material and Methods: Twenty-three patients(16 adults, 7 children) treated for craniopharyngioma between 1990 and 1999 were studied to demonstrate the relationship of tumor size, growth pattern, and its invasiveness with clinical symptoms. As part of the assessment, 16 adults(M : F=8 : 8, mean age : 43.7 years) and 7 children(M : F=5 : 2, mean age : 10.1 years) underwent magnetic resonance(MR) imaging and computerized tomography(CT) scanning with a three-dimensional volume acquisition sequence. Results : The three major cardinal signs were defined to increased intracranial pressure, endocrine dysfunction, and visual problems. The tumor size in child group was larger than that in adult group. Also, visual problems, symptoms of increased intracranial pressure and hydrocephalus were more frequently observed in child group. However, endocrine dysfunction and neuropsychological symptoms related with hypothalamic connections to the thalamus, pituitary, frontal lobe, and other cortical areas were more frequent in adult group. Conclusions: In our series, the tumor size and invasiveness of craniopharyngioma revealed to be relevent with initial symptoms of increased intracranial pressure and visual symptoms which were more frequent in child group. As for the growth pattern, we did not find major difference between adults and children.

Objectives : Vascular endothelial growth factor(VEGF), one of potent cytokines, and its receptors were related with various biological functions and pathological conditions. The purpose of this study was to investigate the changes of serum level of free VEGF, soluble VEGFR-1, and soluble VEGFR-2 after treatment with atypical antipsychotic drug in schizophrenia. Method : The schizophrenic patients were diagnosed with DSM-IV and were prospectively followed up for 4 and 8 weeks. Thirteen schizophrenic patients were evaluated their clinical assessment with serum levels of free VEGF, sVEGFR-1, sVEGFR-2, and positive and negative symptom scale(PANSS) at baseline, 4 weeks, and 8 weeks after treatment with atypical antipsychotic drug. Thirteen normal control subjects were recruited and matched with the patient group by age and sex. Result : The serum level of free VEGF($295.2{\pm}43.7$pg/ml)and sVEGFR-2($8259{\pm}336.7$) at baseline(before treatment) in schizophrenic patients were not significantly different, compared with the control group($199.0{\pm}28.8$ and $8481{\pm}371.9$) respectively. However, the serum level of sVEGFR-1($86.2{\pm}10.3$, p<0.05) was significantly increased in the schizophrenic patients compared with the control group($59.0{\pm}6.4$). After treatment with antipsychotic drug, the serum levels of free VEGF at 4 weeks($338.9{\pm}56.5$) and 8 weeks($309.5{\pm}58.7$) were not significantly, different compared with baseline. But the serum levels of sVEGFR-1 was significantly decreased at 8 weeks ($57.3{\pm}6.3$, p<0.05) after antipsychotic drug treatment. The serum levels of sVEGFR-2 were decreased at 4 weeks ($7761{\pm}403.0$, p<0.05) and 8 weeks($7435{\pm}333.5$, p<0.05) compared with baseline. Conclusion : The decreased serum level of sVEGFR-1 and sVEGFR-2 might be affected by dopaminergic system which was influenced by antipsychotic drug.
Background: Mortality and morbidity of anastomotic complications after esophagectomy have gradually decreased in recent years. However, swallowing difficulties and reflux symptoms after esophagogastrostomy continue to be a burden jeopardizing the quality of life. In the present study, we evaluated the quality of esophagogastrostomy by analyzing anastomotic stenosis and reflux esophagitis. Material and Method: A retrospective analysis was made in 74 patients who underwent esophagogastrostomy after esophagectomy by one surgeon between January 1995 and December 2004. 53 patients of them received endoscopic examination during follow-up($29{\pm}23.6$ months, range $5{\sim}111$ months). Reflux esophagitis and stenosis at anastomostic site were analyzed according to the techniques and locations of esophagogastrostomy. Result: The median age at the time of repair was $60.3{\pm}8.87$ years(range $39{\sim}81$ years). 23 patients received a hand-sewn esophagogastric anastomosis and 30 patients a circular stapled one. There was no significant statistical difference in terms of anastomotic stenosis(p=0.64) and reflux esophagitis(p=0.41) between the two groups. Cervical anastomosis was peformed in 26 patients and intrathoracic anastomosis in 27 patients. No significant statistical difference in anastomotic stenosis between the two groups was found(p=0.44), but reflux esophagitis was noted in 3 patients in the cervical anastomosis group and 14 patients in the intrathoracic anastomosis group(p=0.003). Conclusion: Cervical anastomosis was supposed to have a better quality of esophagogastrostomy by lowering the risk of reflux esophagitis. In the future, the comprehensive study including a patient's subjective symptom and Barrett's metaplasia should be performed in larger cases.
