Abstract
BACKGROUND Parkinsonism is often observed in the elderly. To clarify the prevalence of parkinsonism-associated diseases and conditions, we conducted a population-based study in a rural island town in western Japan, Ama-cho. METHODS Participants included 924 subjects aged 65 years or older residing in the town. Between 2008 and 2011, participants were assessed via standardized neurological examination scales, and Brain MRIs were carried out in 2010. Based on the results of assessment using the modified Unified Parkinson's Disease Rating Scale and a standardized neurological examination, participants were diagnosed as having parkinsonism or mild parkinsonian signs (MPS), or as displaying normal motor conditions (M-normal). RESULTS Of the 729 participants screened, 70 subjects were diagnosed as having parkinsonism, corresponding to a crude prevalence rate of 9.6% (95% CI, 7.9-11.3%), while 167 MPS subjects (22.9%) and 492 subjects experiencing M-normal (67.5%) were observed. Parkinsonism was found in association with various diseases such as Vascular parkinsonism, Lewy body disease, Alzheimer's disease (AD), and idiopathic normal-pressure hydrocephalus. Among the subjects with dementia, the proportion with parkinsonism was higher in the non-AD dementia group. CONCLUSION(S) Parkinsonism occurs in association with several diseases in elderly people. Parkinsonism was also found to be commonly associated with cognitive impairment.

Abstract
BACKGROUND To determine the relationships between regional white matter lesions (WMLs), lifestyle factors, and cognitive, motor function and mood. METHODS A comprehensive evaluation, including brain MRI, blood tests, the Unified Parkinson's Disease Rating Scale, the Mini Mental State Examination, and the Geriatric Depression Scale, was performed for people aged 65 years or older living in Ama-cho on October 1, 2009. Participants were classified by severity of periventricular hyperintensities (PVH) and deep white matter hyperintensities (DWMH) using the Fazekas score. RESULTS Of 900 eligible participants, 688 (76.4%) were enrolled, including 303 men. Significant predictors of severe PVH were older age, lower low-density lipoprotein cholesterol (LDL-C) levels, elevated blood pressure (BP), cerebral infarction, and no current alcohol use. Significant predictors of severe DWMH were older age, lower 1,5-anhydroglucitol (1,5-AG) levels, elevated BP, cerebral infarction, and no current alcohol use. Higher cognitive function was associated with younger age, female sex, mild DWMH, more years of education, and higher high-density lipoprotein cholesterol levels. Depressive symptoms were associated with lower 1,5-AG levels, lower LDL-C levels, moderate to severe PVH, and no current alcohol use. CONCLUSIONS White matter lesions in elderly people were related to hypertension and impaired glucose tolerance. The severity of WMLs was associated with cognitive function and mood.

Abstract
BACKGROUND Fatigue is a common nonmotor symptom of Parkinson's disease (PD). Although the causes of fatigue were estimated in the previous reports, fatigue is not fully understood. To determine the frequency of and factors related to fatigue in patients with PD, we carried out clinical assessments in our university hospital. METHODS We used the Japanese version of the Parkinson Fatigue Scale (J-PFS). The J-PFS was administered to 110 patients with PD, and a cutoff point of 3.3 was used for the diagnosis of fatigue. Subsequently, demographic characteristics, clinical features, and medications utilized were evaluated to elucidate the factors related to fatigue. In particular, we focused on the relationship between fatigue and gait disorder assessed via the portable gait rhythmogram. RESULTS The frequency of fatigue in patients with PD was 52.7%. Univariate analysis revealed that factors significantly associated with fatigue were many motor symptoms and nonmotor symptoms. In addition, multivariate analysis revealed that gait disorder and constipation were independent factors related to fatigue. Furthermore, short-step walking and bradykinesia in gait disorder had especially a relationship with fatigue. CONCLUSIONS More than half of our patients were judged having fatigue. Several factors, including motor and nonmotor symptoms, might be related to fatigue in patients with PD.

Abstract
OBJECTIVES Mild parkinsonian signs (MPS) are reported to be associated with increased risk of dementia, Parkinson's disease, parkinsonism, and vascular lesions of white matter and are also a significant predictor of mortality. Although more than 20% of subjects aged 60 years and older suffer from MPS in Japan, it is often unrecognized and underestimated by patients and medical physicians. We used neuropsychological methods to examine cognitive function and depressive symptoms in subjects with MPS. METHODS We performed a population-based study in Ama-cho, a rural island town in western Japan. Participants included 951 subjects aged 65 years and older, 613 of whom completed all questionnaires, neurological examinations, and neuropsychological assessments and were included in the data analysis. Subjects were assessed for depression and subjective cognitive impairment using the Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), and modified Unified Parkinson's Disease Rating Scale (mUPDRS). RESULTS Of the 613 participants, 143 were diagnosed with MPS. GDS scores were significantly higher in the MPS group compared with the motor control group, while MMSE scores were significantly lower. CONCLUSIONS We demonstrated that MPS correlate with both depressive symptoms and cognitive impairment.

Abstract
Single nucleotide polymorphisms (SNPs) in the interleukin 28B gene (IL28B) are good pretreatment predictors of anti-hepatitis C virus (HCV) therapy with interferon. SNPs of the inosine triphosphatase (ITPA) gene are associated with reduced haemoglobin levels during treatment with ribavirin. The i-densy™ (Arkray, Inc.), which is based on the quenching probe (QP) method, automatically detects target genes in blood samples by fluorescence quenching within 100 min. Using a QP and primer set, a gene amplification response is generated that can quickly and easily detect a specific gene's arrangement by fluorometry. The present study was conducted to compare the utility of i-densy (QP method) with that of conventional direct sequencing (DS) for detecting SNPs in the IL28B and ITPA genes in chronic hepatitis C patients. Between June 2011 and January 2012, 73 consecutive patients underwent genotyping of IL28B, and 54 patients underwent genotyping of ITPA. All of the patients were seropositive for HCV-RNA. The IL28B and ITPA genotypes were tested for bi-allelic polymorphisms in rs8099917 (T/T, T/G and G/G; minor allele, G) and rs1127354 (C/C, C/A and A/A; minor allele, A), respectively. The results obtained with the QP method were identical to those obtained with the conventional DS method. The frequency of the IL28B genotypes TT, GT and GG were 74%, 24.7% and 1.4%, respectively, and those of the ITPA genotypes CC, AC and AA were 68.5%, 29.6% and 1.9%, respectively. These results indicate that the i-densy using the QP method can automatically, quickly and easily identify genotypes of IL28B and ITPA.

Abstract
AIMS In order to determine the prevalence of dementia and mild cognitive impairment (MCI), we conducted a population-based study in Japan. METHODS Participants included 924 subjects aged 65 years or older who resided in the town of Ama-cho. In phase 1 of the study, the Mini-Mental State Examination and Clinical Dementia Rating were administered for screening purposes. In phase 2 of the study, the subjects who screened positive were further examined by neurologists. Dementia and MCI were diagnosed by means of DSM-IV and International Working Group on MCI criteria, respectively. RESULTS By the prevalence date of June 1, 2010, 24 subjects had deceased or lived outside the town. In total, 723 of the remaining 900 subjects received a phase 1 test. In phase 2, 98 subjects were diagnosed with amnestic MCI, 113 subjects with non-amnestic MCI, and 82 subjects with dementia. Of the subjects who did not receive the phase 1 test, 66 subjects were diagnosed as having dementia according to data from their town medical card or the Long-term Care Insurance System. The crude prevalence of amnestic MCI, non-amnestic MCI, and dementia were 10.9, 12.6, and 16.4%, respectively. CONCLUSION Consistent with the striking increase in the number of elderly individuals, we report higher prevalence of MCI and dementia in Japan than previously described.

Abstract
BACKGROUND The prevalence of frontotemporal lobar degeneration (FTLD) in Japan is unknown. An epidemiological survey study of FTLD was undertaken in Tottori Prefecture, a district in the western region of Japan. METHODS Hospitals in Tottori Prefecture were surveyed by a two-step questionnaire in 2010, and the prevalence of FTLD per 100,000 inhabitants was calculated using the actual number of patients and inhabitants in Tottori Prefecture on the prevalence day of October 1, 2010. RESULTS In this survey, 66 patients were diagnosed with FTLD. The subtypes of FTLD were as follows: 62 cases of frontotemporal dementia (FTD), 3 cases of progressive nonfluent aphasia, and 1 case of semantic dementia. Among the FTD cases, 5 cases were FTD with motor neuron disease and 1 case was FTD with parkinsonism linked to chromosome 17. The prevalence of FTD in the total population of Tottori Prefecture was 11.2 per 100,000 inhabitants. Based on these results, the prevalence of FTLD in Japan in 2008 was estimated to be 9.5 per 100,000 individuals. CONCLUSIONS Our epidemiological survey results suggest that there are at least 12,000 FTLD patients in Japan, indicating that FTLD is not a rare disease.

Abstract
Mild parkinsonian signs (MPS) may represent the mild end of a disease spectrum that spans from normal aging to neurodegenerative diseases. We conducted a population-based study in a rural island town in western Japan, Ama-cho. Participants included 1129 subjects, aged 60 years and older, residing in the town. Participants were classified according to a modified Unified Parkinson's Disease Rating Scale (mUPDRS) score. MPS was determined to be present if any of the following conditions were met: (1) two or more mUPDRS ratings=1 [MPS-mild]; (2) one mUPDRS rating≥2; or (3) mUPDRS rest tremor rating≥1; [(2) and (3): MPS-severe]. Subjects wore a uniaxial accelerometer (Actiwatch), resulting in the measurement of actigraphic activity counts (AC). Of the 804 participants with complete data, 178 subjects (22.1%) were classified as demonstrating MPS. AC was significantly lower in the MPS-severe group compared with both the CTL and the MPS-mild groups. Diagnostic sensitivity for MPS-severe became 100% when we adopted a cutoff point of low physical activity, as measured by actigraphy, combined with the presence of subjective depression. We established the prevalence of MPS in a community-dwelling elderly population sample in Japan. Actigraphy may be a useful objective tool for screening MPS-severe.

Abstract
Rapid advances in techniques of magnetic resonance (MR) imaging have enabled diagnosis of acute gynecologic conditions, which are characterized by sudden onset of lower abdominal pain, fever, genital bleeding, intraperitoneal bleeding, or symptoms of shock. The chemical-selective fat-suppression technique not only helps establish the characteristics of lesions that contain fat components but also increases the conspicuity of inflammatory lesions. When a T2-weighted image is obtained with a very long effective echo time (>250 msec), even a small amount of ascites can be easily identified and the contrast between urine and complex fluid becomes more conspicuous. T2*-weighted images are useful for identification of hemorrhagic lesions by demonstrating deoxyhemoglobin and hemosiderin. Contrast material-enhanced dynamic subtraction MR imaging performed with a three-dimensional fast field-echo sequence and a rapid bolus injection of gadopentetate dimeglumine allows evaluation of lesion vascularity and the anatomic relationship between pelvic vessels and a lesion and allows identification of the bleeding point by demonstrating extravasation of contrast material. To optimize the MR imaging examination, attention should be given to the parameters of each pulse sequence and proper combination of the sequences.

Abstract
Pharmacokinetic and clinical evaluation of an injectable cephem antibiotics, cefozopran (SCE-2787, CZOP), was conducted in newborn patients and the following results were obtained: 1. Clinical results The clinical efficacy of CZOP was evaluated in one each patient with intrauterine infection and suspected septicemia. The efficacy was "excellent" in both patients. No clinically serious adverse drug reactions of signs and symptoms and abnormal alterations of the laboratory test values were recognized. 2. Pharmacokinetics CZOP was intravenously given to newborn patients at doses of 25.0, 20.0, and 18.75 mg/kg. The blood CZOP concentrations were 44.7 +/- 7.0 micrograms/ml (n = 3), 48.3 micrograms/ml and 48.2 micrograms/ml at one hour after administration, respectively. The elimination half life (T 1/2) was 4.22 +/- 1.17 hours (n = 3) in the patients given 25.0 mg/kg and 2.74 hours in the patient given 20.0 mg/kg. The urinary drug excretion rate was 44.5 +/- 8.7% and 31.3 +/- 9.7% of dose within 8 hours after administration of 25.0 mg/kg and 20.0 mg/kg, respectively.

Abstract
Pharmacokinetic and clinical studies of flomoxef (FMOX) in neonates and premature infants were conducted, and the results obtained are summarized below. 1. Plasma concentrations of FMOX at 15 minutes after one shot intravenous injection of 20 mg/kg to 6 cases were in a rang of 33.0-69.9 micrograms/ml and half-lives (T 1/2's) were between 0.68 and 4.89 hours. The plasma concentration of FMOX at 15 minutes after one shot intravenous injection of 40 mg/kg to 1 case was 79.9 micrograms/ml and the half-life (T 1/2) was 2.45 hours. Drug concentrations in plasma upon 1-hour intravenous drip infusion were 71.1-114.0 micrograms/ml and T 1/2's were 1.64-3.41 hours. T 1/2 tended to be couse shorter as ages of babies increased. 2. Urinary excretion rates in the first 6 hours after one shot intravenous injection of FMOX 20 mg/kg to 1 case and 1-hour intravenous drip infusion of FMOX 40 mg/kg to 2 cases were 60.4%, and 27.2 and 55.3%, respectively. 3. Clinical effects of FMOX against 12 cases of bacterial infections were excellent in 6 cases, good in 5 cases and poor in 1 case, thus the clinical efficacy rate was 91.7%. FMOX was also given to 6 cases for prophylaxis and prophylactic effects were observed in all the cases. 4. No adverse effects were observed in the 21 cases examined, but elevations of S-GOT and S-GPT were found in 1 case. The abnormal laboratory test results were probably due to this drug.
