Oral Health Status of Children and Adolescents by Rural Residence, United States

CONTEXT: The limited information available on the oral health status of rural children in the United States makes it difficult to devise policy strategies to address perceived problems. PURPOSE: To document the oral health status and dental care utilization of US children by place of residence, METHODS: Data from National Health Interview Surveys for 1995, 1997, and 1998, and from the third National Health and Nutrition Examination Survey (1988-1994) were analyzed. FINDINGS: Children residing in rural areas were more likely to be uninsured for dental care than were children from urban areas (41.1% versus 34.7%). A greater percentage of rural than urban children reported unmet dental needs (7.5% versus 5.6%); there was no difference in self-reported poor dental status. Urban children were more likely than rural children to have visited the dentist in the past year (73.6% versus 69.9%) and were also more likely to be regular users of dental care (61.7% versus 51.4%). Differences in percentage of rural and urban children with caries lesions and caries experience were not significant. CONCLUSIONS: Children residing in rural areas have less access to and utilization of dental care compared to children residing in urban areas. Moreover, poor rural children display less utilization of dental services than poor urban children. Differences in the sum of decayed and filled primary teeth and the sum of decayed, missing, and filled permanent teeth were not significant.     

The structure of wandering in dementia

‘Wandering’ is one of the most troublesome of behavioural problems in dementia. The term ‘wandering’ covers many different types of behaviour. We examined the hypothesis that the different types of wandering behaviour seen in dementia from a scale using data collected on 83 elderly subjects suffering from either Alzheimer's disease or multiinfarct dementia. We reject the scaling hypothesis. Our data suggest that there are three main categories of wandering behaviour, and that one of these categories is usefully divided into four subcategories.     

Neuroleptic malignant syndrome induced by ziprasidone on the second day of treatment.

Neuroleptic malignant syndrome (NMS) is the rarest and most serious of the neuroleptic-induced movement disorders. We describe a case of neuroleptic malignant syndrome (NMS) associated with the use of ziprasidone. Although conventional neuroleptics are more frequently associated with NMS, atypical antipsychotic drugs like ziprasidone may also be a cause. The patient is a 24-year-old male with a history of schizophrenia who developed signs and symptoms of NMS after 2 days of treatment with an 80-mg/day dose of orally administrated ziprasidone. This case is the earliest (second day of treatment) NMS due to ziprasidone reported in the literature.     

新药给糖尿病患者带来希望

竞争已经拉开了序幕。对1型和2型糖尿病,各个制药厂家都希望通过研发可以更好的治疗疾病、改善患者生活质量以及最终能彻底的预防糖尿病并发症发生的新治疗方法来获得在这一领域内的重要位置。对于1型糖尿病来说,主要的趋势就是向人工胰腺发展从而可以更好的控制病情、预防或者降低疾病的并发症。可以实现此目标第一步的技术已经存在,包括DexCom有限公司的STS连续血糖检测系统(STS Continuous Glucose Monitoring System,于2005年通过FDA批准)以及最近才通过批准的美敦力有限公司的Guardian实时系统(Guardian REAL-TimeSystem)以…     

Emerging Patterns in Adolescent Drug Use: The Belfast Youth Development Study 2000-2002

This paper reports the findings from the first 2 years of the Belfast Youth Development Study. The Belfast Youth Development Study is a 5-year longitudinal investigation of the onset and development of adolescent drug using behaviours, the findings of the first 2 years from the study in relation to drug use patterns among the young people participating in the research are reported here. The findings show that while the majority of young people have not yet used an illicit substance, the study has seen a substantial increase in the numbers using such substances between year 1 and year 2. Boys still make up the majority of drug users in this period but there has been a substantial increase in the number of girls using illicit drugs and, more generally, an increase in the frequency of use among all those using such substances during this period.     

The lateral chest X-ray: Is it necessary for emergency department patients?

To determine the utility of the lateral view of the chest in emergency department patients, records of all patients who had had 2-view chest x-rays ordered in the emergency department were reviewed retrospectively. A study radiologist recorded a reading of the posteroanterior (PA) radiograph alone. The lateral radiograph was then provided, along with the PA view, and a second reading was recorded. A comparison was then made between the first and second readings.A total of 417 sets of x-rays were included. The PA view alone successfully diagnosed or suspected 92% of pulmonary nodules, 95% of effusions, 97% of cases of emphysema, 98% of pneumonias, and 100% of cases of cardiomegaly, pulmonary edema, interstitial pulmonary disease, and atelectasis.In the emergency department patient population, lateral views of the chest have minimal diagnostic yield and therefore may be used selectively to safely decrease the amount of breast radiation exposure to young women.
