    ABSTRACT: To describe a patient with prodromal dementia with Lewy bodies (DLB) manifesting as sertraline-induced parkinsonism. Case report. Tertiary referral center. A 75-year-old man who initially presented with anxiety and depression along with mild cognitive impairment, later developed drug-induced parkinsonism because of sertraline treatment, and eventually showed symptoms and signs of probable DLB. Sertraline treatment for depression. : Clinical examination, magnetic resonance imaging, neuropsychologic test, and cardiac I-metaiodobenzylguanidine scintigraphy. His parkinsonian symptoms, which became apparent after sertraline therapy, improved markedly after the discontinuation of the drug. When he started taking sertraline, he had no dementia but had mild cognitive impairment. However, he eventually showed most of the symptoms and signs to indicate probable DLB. To our knowledge, there has been no report of sertraline-induced or aggravated parkinsonian motor symptoms in DLB patients. Our patient had a short period with neither dementia nor parkinsonism during the early stage of his illness, and this period might have been regarded as the preclinical stage of DLB in the natural course of his illness.

    ABSTRACT: Hemimasticatory spasm (HMS) is a rare disorder of the trigeminal nerve characterized by paroxysmal involuntary contractions of the unilateral jaw-closing muscles. HMS has been frequently described in association with facial hemiatrophy or localized scleroderma. A 42-year-old female presented with involuntary paroxysmal spasms of the left face, of 6 months duration. Her lower face on the left was markedly hypertrophied without skin lesions. An electrophysiological study indicated that the masseter reflexes and masseteric silent period were attenuated on the affected side. Surface electromyography demonstrated irregular bursts of motor unit potentials at high frequencies up to 200 Hz. Magnetic resonance imaging of the head showed marked hypertrophy of the left masseter muscle. Biopsy of the hypertrophied masseter muscle was normal. Repeated local injections of botulinum toxin noticeably reduced the size of the hypertrophied muscle as well as improved the patient's symptoms.

    ABSTRACT: To investigate if diabetes is more common in drug-induced parkinsonism patients. We performed a hospital-based retrospective case-control study on 44 drug-induced parkinsonism (DIP) patients, 177 Parkinson disease patients, and 176 acute stroke patients matched for age and sex who were seen over the same period at the same hospital. The frequency of diabetes, age-at onset and sex were compared between DIP and IPD or acute stroke. Multivariate analysis showed that patients with diabetes are more frequent in DIP compared with IPD (p<0.001, adjusted OR 5.48; 95% CI, 2.52-11.94). The frequency of diabetes in DIP was comparable to that in acute stroke patients (p=0.16, adjusted OR 0.62; 95% CI, 0.32-1.21). These data suggest that diabetes may be a risk factor for DIP. Drugs with dopamine receptor blocking potency should be avoided in elderly with diabetes.

    ABSTRACT: Short life expectancy influences decision-making when treating very old patients with acute ischemic stroke (AIS). We investigated mortality and survival duration in very old AIS patients (>or= 80 years) who received hospital care. Mortality data were obtained from medical records, structured telephone inquiries, death certificates from the Korean National Statistical Office, and social security data 5+/-1.9 years after stroke onset. Age, gender, vascular risk factors, and functional outcomes from modified Rankin scales (MRS) at discharge were analyzed as predictors of mortality. Among 134 patients, 92 (68.7%) died. On Kaplan-Meier analysis, duration of survival of patients aged 80-84 years was longer than those aged 85-89 or 90-94 (24+/-6.4, 8+/-7.3, 7+/-2.0 months, respectively, p=0.002). Duration of survival of patients discharged in a state of MRS 0-1 was longer than the remaining groups at 47+/-4.8 months (p<0.001). In Cox proportional hazard analysis, age and MRS at discharge were independent predictors of mortality. Long-term outcomes of very old patients with AIS are not uniformly grave, therefore predictors of mortality and estimated duration of survival should be considered during decision-making for treatment.

    ABSTRACT: An aging-suppressor gene, klotho, is a candidate factor for vascular disease because its deficiency leads to impaired endothelium-dependent vasodilation and impaired angiogenesis. We investigated the association of polymorphisms in klotho with ischemic stroke. We searched for sequence variants in promoter and exons of klotho gene. For the association study, selected variants were genotyped in control subjects and in patients with ischemic stroke and vascular dementia. The association with ischemic stroke was further investigated with its subtypes classified based on Trial of Org 10172 in Acute Stroke Treatment (TOAST). No significant association was observed for both G-395A and C1818T with ischemic stroke and vascular dementia (P>0.05). The analysis with subtypes of ischemic stroke revealed the associations that the A allele of G-395A increased the risk of cardioembolic stroke (CE, OR=2.60; P=0.006), and subjects carrying the A allele were susceptible to CE in both of dominant (AA+GA versus GG; OR=2.50; P=0.046) and recessive (AA versus GA+GG; OR=6.52; P=0.007) models. Further analysis of data partitioned by gender showed that the associations of G-395A with CE only existed in women (A versus G; OR=4.33; P=0.002), AA+GA versus GG; OR=5.68; P=0.014, and AA versus GA+GG; OR=9.07; P=0.012), but the significance disappeared in men (P>0.05). The sequence variant of G-395A in klotho might be a genetic risk factor for CE in females.

    ABSTRACT: Sequence variants of angiotensin converting enzyme (ACE) insertion/deletion (I/D), angiotensinogen (AGT) T235M, angiotensin II type 1 receptor (AT1R) A1166C, and plasminogen activator inhibitor-1 (PAI-1) 4G/5G were analyzed to see their genetic associations with vascular dementia as its candidate genetic risk factors involving renin-angiotensin and fibrin systems. While the ACE I/D, AT1R A1166C, and PAI-1 4G/5G did not contribute to the genetic susceptibility to vascular dementia (P>0.05), a significant association with vascular dementia was shown in the T235M polymorphism of AGT. The frequency of the M allele in patients was higher than in controls with the odds ratio (OR) estimate of 1.51 (P<0.05). In a dominant model, the TM+MM genotypes increased the risk of vascular dementia compared to the TT genotype (OR=2.01; P<0.001). The current results suggested that AGT T235M polymorphism might be a risk factor of vascular dementia.

    ABSTRACT: Background : Increasing incidences of epilepsy in the elderly are well-known. However, the causes of newly onset seizures in the elderly have rarely been described in Korea. Methods : We selected 160 cases of individuals who had their first seizure at over the age of 60 (male : female = 1.5 : 1 ; mean age : 69.1 years), who were admitted to Hallym University Hospital from July 1, 1994 to June 31, 1998. We analyzed the etiology, type of seizures, EEG, neuro-imag - ing, morbidity and mortality of the patients. R e s u l t s : The etiologies of seizures were remote symptomatic in 87 (54.3%), acute symptomatic in 38 (23.8%), progressive encephalopathy in 21 (13.1%), and idiopathic in 14 (8.8%). Status epilepticus occurred in 34 cases, including 8 cases of multifocal myoclonic status after hypoxic brain damage. The most common single cause of seizure was old stroke (35%, infarction in 41 and hemorrhage in 15 cases). Partial seizure was more common in patients with remote symptomatic than with other causes. Newly developed neurological deficits were present in 30 of the 151 who survived, including 15 acute symptomatic, 9 remote symptomatic, and 6 pro - gressive encephalopathy cases. Morbidity and mortality were highest in the acute symptomatic group ( P

    ABSTRACT: A multiplex real-time polymerase chain reaction (PCR) kit was developed for the qualitative detection of the Roundup-Ready Soybean (RRS). This system consists of a screening assay for cauliflower mosaic virus 35S promoter and nos terminator, and an event-specific assay for RRS containing the lectin gene as an internal positive control. The limit of detection value was determined to be approximately 0.1%.
