BACKGROUND: Drug-induced Parkinsonism(DIP) is the second commonest cause of Parkinsonism, after idiopathic Parkinson's disease(IPD). DIP is frequently produced by antipsychotic drugs. But the clinical characteristics of DIP did not get attention by neurologist. So we studied the clinical profiles of DIP patients. METHODS: We studied the clinical profiles of thirthone patients who showed parkinsonism after antipsychotic drug treatment. We compared the score of motor part of the Unified Parkinson's Disease Rating Scale(UPDRS) between trihexyphenidyl(n=15) & amantadine(n=16) monotherapy group(initial & 4 week after treatment). RESULTS: The mean age of patients was 45 years. Bradykinesia was the 1st symptom in 26 patients(94%), tremor in 5 patients(6%). In 25 patients(81%), the first symptom appeared within 1 week after sntipsychotic treatment. There was a statistical significant negative correlation between the dosage of antipsychotic drug and the symptom-onset interval following treatment with antipsychotic drugs(simple correlation analysis, p>0.01). Bradykinesia and rigidity were appeared in all DIP patients, symmetric distribution was more common(94%, 87%) Tremor occurred in 27 patients (87%). In patients with tremor, postural or action tremor was dominant in 15 patients(56%) asymmetric distribution was more common(16/27, 59%). There are no statistical difference in motor score of UPDRS between trihexyphenidyl & amantadine monotherapy group(student t-test, p<0.05) CONCLUSIONS: Bradykinesia was the most common 1st symptom in DIP patients. Asymmertrical postural or action tremor was relativelly common in DIP. Amantadine showed the same efficacy in the treatment of DIP compared to anticholinergics.

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology. The total DALYs per 100,000 population were 376 in maternal disorders, 64 in neonatal disorders, and 58 in nutritional deficiencies. The leading causes of DALYs were abortion in maternal disorders, preterm birth complications in neonatal disorders, and iron-deficiency anemia in nutritional deficiencies. Our findings shed light on the considerable burden of maternal, neonatal, and nutritional conditions, emphasizing the need for health care policies that can reduce morbidity and mortality.

BACKGROUNR/AIMS: Heterogeneity of liver cell populations within the hepatic lobules can affect xenobiotic reaction. In this study, we attempt to clarify the stereological distribution of the y-GTP positive foci in hepatic lobule initiated by diethylnitrosamine and promoted by phenobarbital. METHODS/METERIALS: To the five Sprague-Dawley rats, one day after birth, diethylnitrosamine (0.15 pmole/pn) was intraperitoneally injected and by the weaning at four weeks of life, 0.035% phenobarbital in drinking water was fed for four weeks, at which time the rats were sacrified to obtain the livers. Livers were fixed in fresh cold ethanol acetic acid. Ihe 200 cotmecutive tissue sections were stained by histochemistry for y-GIP and countastained with toluidine blue ar HkE. Employing Zeiss microprojector, y-GTP foci wae traced. And then the largest cross-sectian (size class: 65-165 pm in diameter) of 52 y-GTP foci were selected. Using microscopic grid, distances fiom center of y-GlP foci to nearest centtal vein and bile ductule was measured. As a control group, out of 52 random points determined by rareken digit table, the distances were measured by the same romr. RESULT: the diameter Aom the central points of y-GIP positive foci to the neatest bile ductules was measured as 0.234620+0.14899mm (mean+SD) and the diameter from random points to the neatest bile ductules was measured as 0.303080+0.19582mm (mean+SD). Y-GTP positive foci located within 0.3mm diameter fram bile ductules were counted as 73.1% of 52 foci, whereas that of random points were only 55.8%. Accoring to Aequency table analysis by Shapiro-Wilk W test, there was significant difference by W-value (0.812065) and p-value (0.0144866). CONCLUSION: Stereologically, y -GTP positive foci initiated by diethylnitros;unine, promoted by phaxkarbital in neonatal Spague-Dawley rats were non-rarxlanly distributed in peripcetal atea (Rappaport zone I) in hepatic lobule during hepatocarcinogenesis.

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

In patient with Zollinger-Ellison syndrome, it is difficult to localize gastrinoma because the tumor is frequently small and multiple. However, accurate localization of the tumor is important for the treatment. Among various imaging modalities, somatostatin receptor scintigraphy (SRS) has been recognized to be the most sensitive tool for the detection of neuroendocrine tumors such as gastrinomas based on the presence of high-affinity binding sites for somatostatin. Recently, we experienced a case of Zollinger-Ellison syndrome caused by gastrinomas which was localized by SRS. This is the first case report of gastrinoma detected by SRS in Korea. SRS can facilitate tumor detection in patient with Zollinger-Ellison syndrome and should be considered as the first-line diagnostic method in the early course of the disease.

OBJECTIVES: This study sought to evaluate trabecular changes in the mandible using fractal analysis and to explain the transient osteopenia related to rapid orthodontic tooth movement after orthognathic surgery. MATERIALS AND METHODS: Panoramic radiographs were taken of 26 patients who underwent bilateral sagittal split ramus osteotomy. Radiographs taken before the surgery and 1 month after surgery were overlapped, and 40x40 pixel square regions of interest were selected near the mandibular canines and 1st molars. After the image processing procedure, the fractal dimension was calculated using the box-counting method. RESULTS: Fractal dimension after orthognathic surgery decreased in a statistically significant manner (P<0.05). The change in fractal dimension on the canine side had greater statistical significance as compared to that seen on the 1st molar side. CONCLUSION: This study found that bone density decreases after orthognathic surgery due to transient osteopenia related to the regional acceleratory phenomenon. This result can provide a guide to evaluating orthodontic tooth movement after orthognathic surgery.

OBJECTIVES: Little is known about the influence of urinary incontinence and depression on individual's QOL(Quality of life). We aimed to clarify how the interaction between urinary incontinence and depression influences one's QOL. METHODS: A total of 1262 patients were enrolled in this study from April, 2011 to July, 2011. We estimated the severity of depressive symptoms and QOL, using SGDS-K, EQ-5D. We also investigated the morbidity of urinary incontinence for each patient in person or by questionnaire. Comparisons of QOL between groups with or without depression, with or without urinary incontinence were established using t-test, ANOVA and Scheffe's post hoc analysis. The interaction between urinary incontinence and depression was analyzed by each domain of QOL, using multiple regression analysis. RESULTS: Patients with depression and urinary incontinence showed significantly higher EQ-5D scores on every domain of QOL than other patients, which means significantly lower QOL. Patients with depression, no urinary incontinence reported lower QOL, especially in the domain of ‘usual activity’, ‘anxiety’ and ‘visual analogue scale(VAS)’, whereas those with urinary incontinence, no depression showed lower QOL in ‘motility’, ‘usual activities’ and ‘pain’ domain. Statistically significant interaction effects of two diseases were observed in the domain of ‘VAS’, ‘self care’ and ‘anxiety’. CONCLUSIONS: Comorbidity of urinary incontinence and depression showed significantly lower QOL of patients, compared with urinary incontinence or depression respectively, which implies additive interaction effects of the two diseases. Optimal diagnosis and treatment of depression should be emphasized for patients with urinary incontinence.

Organized hematoma of maxillary sinus is a rare pathologically benign mass in which pressure in the hematoma increases as it undergoes a process of organization, causing the deformation of the surrounding tissue, mimicking malignancies. The midfacial degloving approach can be used when extensive exposure is required in the treatment of lesions or traumas in the midfacial area with intranasal and intraoral incisions. We report a surgical excision case of organized hematoma of maxillary sinus using midfacial degloving approach without major complications and recurrence after one-year follow up.

Endometriosis is a common gynecologic disease, it occur not only pelvic organ but also anywhere in human body. However inguinal endometriosis is a very rare condition, its incidence is 0.4% of entire endometriosis. Most of inguinal endometriosis are found as inguinal masses in women in 30s and 40s who have history of gynecologic surgery. Majority of the cases are accompanied with pelvic endometriosis. Authors report a case of inguinal endometriosis in patients who has no history of gynecological surgery.

Silent information regulator 2 (Sirtuin2 / SIRT2) is a NAD⁺-dependent deacetylase that regulates the cellular oxidative stress response. It modulates transcriptional silencing and protein stability through deacetylation of target proteins including histones. Previous studies have shown that SIRT2 plays a role in mood disorders and hippocampus-dependent cognitive function, but the underlying neurobiological mechanism is poorly understood. Here, we report that chronic stress suppresses SIRT2 expression in the hippocampus. Molecular and biochemical analyses indicate that the stress-induced decrease in the SIRT2 expression downregulates synaptic plasticity-related genes in the hippocampus through the increase of euchromatic histone-lysine N-methyltransferase 2 (Ehmt2) (also known as G9a). shRNA-mediated knockdown of SIRT2 in the dentate gyrus alters the expression of synaptic plasticity-related genes in a way similar to those induced by chronic stress, and produces depression-like behaviors. Our results indicate that SIRT2 plays an important role in the response to stress, thereby modulating depression-like behaviors.
