Therefore, for those genotoxic and carcinogenic contaminants (e.g. acrylamides, PAHs, etc.) in foods it is not possible to develop health-based guidance values (e.g. ADI or PTWI) using the traditional NOEL and safety/uncertainty factors.展开更多

OBJECTIVE： To comparatively observe the difference in accompanying diseases, transcranial doppler （TCD） performance, blood glucose and blood lipid level between BD patients and healthy subjects who received health examination, and between BD patients with different disease condition. DESIGN ： Case-control analysis SETTING ： Department of Emergency, Qingdao Municipal Hospita PARTICIPANTS： Totally 126 patients with BD, 65 male and 61 female, aged from 67 to 85 years old, who hospitalized in the Medical School Hospital of Qingdao University and Qingdao Municipal People＇s Hospital, were chosen, serving as BD patients group. All the patients met the clinical diagnostic criteria of BD introduced by Bennett et al. Another 126 persons, 65 male and 61 female, aged ranging from 67 to 80 years, who received health examination in the same hospital, were homeochronously chosen, serving as control group. Informed consents were obtained from all the subjects. METHODS ： After being admitted, all the subjects including BD patients and persons who homeochrenously received health examination in the same hospital were given examinations of blood pressure, blood lipid, blood glucose, electrocardiogram （ECG） and TCD. Fifty-seven patients with BD were in the stable period and 69 in the progressive period （Stable period： no local or subcortical function disorder found, and no changes in the range of white matter lesion showed by CT and/or MRI in recent 3 months; Progressive period： with local or subcortical function disorder and increase in the range of white matter lesion showed by CT and/or MRI in recent 3 months）. According to intimal thickening of carotid artery and vertebral artery preformed by TCD, BD was graded as mild intimal thickening （〈 1.1 mm）, moderate intimal thickening （1.1 to 1.2 mm） and severe intimal thickening （〉 1.2 mm）. MAIN OUTCOME MEASURES ： Comparison of the ratio of BD patients with accompanied diabetes mellitus, hypedipemia, coronary heart disease and transient ischemic attacks, TCD performance, blood glucose and blood lipid level between BD patients group and control group, and among BD patients with vadous disease conditions. RESULTS： Totally 126 BD patients and 126 subjects who received health examination all participated in the result analysis. Intergroup comparison： ①The ratio of BD patients with accompanied hypertension, diabetes mellitus, hypedipemia, transient ischemic attacks and coronary heart disease was 91.3%, 46.8%, 42.9%, 81.7% and 46.0% respectively in the BD patients group, and that was 36.5%, 17.5%, 15.9%, 34.1% and 34.1%, respectively in the control group. Significant difference existed between two groups （x^2=86.201, 24.907,25.660,58.620,9.900, P 〈 0.01 ）.②Compared with control group, anterior, middle cerebral and vertebrobasilar arteriosclerosis and insufficient cerebral blood supply existed significantly in BD patients with different disease condition （x^2=40.34,7.585,15.429, P 〈 0.01 ）.③Compared with control group, the level of blood glucose, total cholesterol and triglyceride of BD patients increased significantly （t=6.939,3.891,3.711 ,P 〈 0.01 ）. Comparison among BD patients with different disease condition： ① Compared with stable period, transient ischemic attacks and coronary heart disease were found much in the BD patients at progressive period, with significant difference （x^2=7.196,13.517,P 〈 0.01 ）.② Mild arteriosclerosis at stable period was found in 17 cases, and significant difference existed compared with progressive period （x^2=6.523,P 〈 0.05）.③ There was no significant difference in the blood glucose and blood lipid level （t=-1.755 6,0.583 1,0.824 6, P 〉 0.05）. CONCLUSION： Hypertension, cerebral arteriosclerosis, diabetes mellitus, hypedipemia, coronary heart disease and transient ischemic attacks have important effects on the onset of BD; Transient ischemic attacks and coronary heart disease can worsen the symptoms of BD patients.展开更多

Purpose: To determine the prevalence, socio-demographic profile, aetiologies, and the clinical presentation of developmental delay in children less than 6-year-old at the child neurology unit in a university-affiliated hospital in Yaounde. Materials and methods: It was a crosssectional descriptive study carried out in Yaounde Gynaeco-Obstetric and Paediatric Hospital (Cameroon) from August to December 2012. Children aged between 5 - 72 months with a developmental quotient less than 70 were enrolled. Developmental delay (DD) was diagnosed and classified using the Denver developmental screening test (DDST). Data concerning the child (age, gender, severity of DD), the mother (age, age at conception, educational level, marital status), history of pregnancy and delivery, perinatal and postnatal events, results of para-clinical explorations (EEG, CT-scan, genetic tests), the severity of DD and the probable or demonstrate cause of DD were recorded on a standardized questionnaire. The chisquare test was used to compare variables. Results: During the study period, 2171 children aged 5 - 72 months consulted the paediatric department of the hospital, 296 were examined at the child neurology unit of which 153 had a developmental quotient less than 70, giving a hospital prevalence of 7.0% and a prevalence of 51.7% at the child neurology unit. The mean age was 26.6 ± 18.0 months and there were 56% males. The main reason for consulting was tonus disorder (43.8%) and the developmental area of parental concern was the motor domain (90.2%). Regarding the clinical presentation, 75.2% of our population were children with cerebral palsy. DD was severe, mild, moderate and profound respectively in 14.2%, 13.5%, 12.2%, and 11.1%. Gross DD represented 90.2% of all DD children. The causes of DD were hypoxic-ischemic encephalopathy (41.8%), epilepsy (13.7%), sequelae of meningitis (6.5%), sequelae of kernicterus (6.5%), and infectious embryofoetopathies (5.2%). Conclusion: Developmental delay is frequent in paediatric neurology, with perinatal disorders being the leading aetiologies in Cameroon. Prevention of perinatal hypoxic-ischemic encephalopathy risk factors needs to be reinforced.展开更多
