In England and Wales hospital admissions for childhood asthma almost trebled over the period 1975-81. This may have reflected a true increase in the incidence of acute asthma, a swing from primary to hospital care, or both. The trend was not due to a change in diagnostic fashion. Monthly admissions showed a pronounced seasonal variation with fewest admissions in winter, rising in spring and early summer to peak in the autumn. A deep admission trough was present in August. The monthly admission profile was very similar throughout England and Wales, suggesting that major "trigger" factors were responsible. 相似文献

Monthly trends in deaths attributed to asthma in the 5-34 year age group were examined for England and Wales over the period 1960-82. Deaths were most frequent in the third quarter (July to September) and peaked in August. Analysis of the 1970-82 period showed that this variation was present in the three constituent age groups 5-14, 15-24, and 25-34 but was most pronounced in the 5-14 year olds. 相似文献

Objectives: To describe the clinical health status and subjective oral health status of older adults from minority ethnic communities resident in South East England. Design: Cross sectional survey incorporating a clinical examination and a questionnaire assessment of subjective oral health status. Setting: Community groups working with individuals from minority ethnic communities. Subjects: A total of 540 individuals from 7 minority ethnic communities. Measures: Clinical assessment of oral health status using BASCD criteria. Assessment of oral symptoms and impact experienced together with satisfaction with oral status, by structured questionnaire. Results: On all measures of clinical health status the participants were healthier than a comparison group based on data from the Adult Dental Health Survey. The participants expressed high levels of subjective oral symptoms. Levels of satisfaction were lower than those found in the Adult Dental Health Survey. There was evidence of some variation across minority ethnic communities in clinical and subjective oral health status. Conclusions: Approximately 20% of the 540 adults from minority ethnic communities resident in the South East of England surveyed were relatively fit orally. They experienced a great many oral symptoms, and in approximately 30% of individuals these were sufficient to interfere with their quality of life. Ethical approval: The research described in this paper was approved by the Ethics committee of King's College London. 相似文献

ObjectiveTo determine the incidence of epilepsy in a general practice population and its variation with socioeconomic deprivation.DesignProspective surveillance for new cases over an 18 or 24 month period.ParticipantsAll patients on practice registers categorised for deprivation with the Carstairs score of their postcode.Setting20 general practices in London and south east England.Results190 new cases of epilepsy were identified during 369 283 person years of observation (crude incidence 51.5 (95% confidence interval 44.4 to 59.3) per 100 000 per year). The incidence was 190 (138 to 262) per 100 000 in children aged 0-4 years, 30.8 (21.3 to 44.6) in those aged 45-64 years, and 58.7 (42.5 to 81.0) in those aged ⩾65 years. There was no apparent difference in incidence between males and females. The incidence showed a strong association with socioeconomic deprivation, the age and sex adjusted incidence in the most deprived fifth of the study population being 2.33 (1.46 to 3.72) times that in the least deprived fifth (P=0.001 for trend across fifths). Adjustment for area (London v outside London) weakened the association with deprivation (rate ratio 1.62 (0.91 to 2.88), P=0.12 for trend).ConclusionsThe incidence of epilepsy seems to increase with socioeconomic deprivation, though the association may be confounded by other factors.
What is already known on this topic
Epilepsy is associated with a wide range of markers of social and economic disadvantageA small number of epidemiological studies have confirmed this association but have not established the direction of causalityWhat this study adds
The incidence of epilepsy, adjusted for age and sex, in the most deprived fifth of the study population was 2.3 times that in the least deprived fifthSocioeconomic deprivation is an important risk factor for the development of epilepsy, though the results may partly reflect differences in incidence within and outside London 相似文献6.

We investigated the distribution of ribonucleic acid (RNA) coliphages in the Philippines, Singapore, Indonesia, India, and Thailand by collecting sewage samples from domestic drainage in November 1976. Of the 221 samples collected from domestic drainage, 50 contained RNA phages (52 strains). By serological analysis, 46 of the 52 strains were found to belong to group III. It can thus be said that the most prevalent RNA phages in Southeast Asia (at least, in the Philippines, Singapore, and Indonesia) were group III phages. Investigations of sewage samples collected from domestic drainage in Japan indicate that the most prevalent RNA phages in mainland Japan (north of Kyushu) are group II phages, whereas group III phages are predominant in the southern part of Japan (south of Amamiohshima Island). We therefore propose a borderline between Kyushu and Amamiohshima Island for the geographical distribution of RNA coliphages in the domestic drainage of South and East Asia. Moreover, one strain (ID2) was inactivated to some extent with the antisera of four groups of RNA phages. This is thought to be significant from the evolutionary viewpoint. 相似文献

BackgroundSeveral studies have reported a seasonal trend in the diagnosis of childhood cancer suggesting seasonal factors such as infection. The present study aimed to analyze the diagnosis pattern of childhood malignant diseases using public health data, and to compare this pattern with seasonal viral infection trends.MethodUsing the open data source of the Health Insurance Review and Assessment Service, we extracted data regarding all patients under 21 years of age and who had any cancer, aplastic anemia or myelodysplastic syndrome between September 2009 and December 2013. The positive detection rates of 11 viruses was collected from the surveillance data of Korea Centers for Disease Control and Prevention, and seasonality analysis were conducted with both data.ResultsIn total, 9085 patients were diagnosed with malignant disease during the study period; there were about 175 new cases per month on average. Monthly stacked time series by year showed an apparent seasonal variation with the highest monthly average in January as 236, and the lowest in September as 120. In winter, significantly more patients were diagnosed with acute lymphoblastic leukemia, acute myeloid leukemia, neuroblastoma, and Hodgkin’s lymphoma than in other seasons. There was a temporal correlation with the diagnostic trends of several diseases and the prevalence of recent human parainfluenza virus.ConclusionThis study tentatively suggests that the diagnosis of childhood malignancy follows a seasonal trend in Korea, and has a possible correlation with viral prevalence in several diseases. Further long-term analysis of epidemiological data is needed to explore possible causality. 相似文献

Objectives: To examine the relation between deprivation and acute emergency admissions for cancers of the colon, rectum, lung, and breast in south east England. Design: Ecological analysis with data from hospital episode statistics and 1991 census. Setting: North and South Thames Regional Health Authorities (population about 14 million), divided into 10 aggregations of 31 470 census enumeration districts (median population 462). Subjects: 146 639 admissions relating to 76 552 patients aged <100 years on admission, resident in the Thames regions, admitted between 1 April 1992 and 31 March 1995. Results: Residents living in deprived areas were more likely to be admitted as emergencies and has ordinary inpatient admissions and less likely to be admitted as day cases. Adjusted odds of ordinary admissions from the most deprived tenth occurring as emergencies (relative to admissions from the most affluent tenth) were 2.29 (95% confidence interval 2.09 to 2.52) for colorectal cancer, 2.20 (1.99 to 2.43) for lung cancer, and 2.41 (2.17 to 2.67) for female breast cancer; adjusted odds of admissions as day cases were 0.70 (0.64 to 0.76), 0.50 (0.44 to 0.56), and 0.56 (0.50 to 0.62), respectively. Patients from deprived areas with lung or breast cancers were less likely to be recorded as having surgical interventions. Adjusted odds of patients from the most deprived tenth receiving surgery were 0.88 (0.78 to 1.00), 0.58 (0.48 to 0.70), and 0.63 (0.56 to 0.71), respectively. Admissions for colorectal cancer from the most deprived areas were less likely to be to hospitals admitting 100 or more new patients a year; the opposite held true for breast cancer admissions. No association was found for lung cancer admissions. Conclusions: Earlier diagnostic and referral procedures in primary care in deprived areas are required if there are to be significant reductions in mortality from these cancers. A national information strategy is required to ensure the continued availability of population based data on NHS patients and to mandate standardised datasets from the private sector. Rationalisation of acute services, hospital mergers, and plans for bed closures must take into account the increased healthcare needs and inequities in access to treatment and care of residents in areas with high levels of deprivation. Health authorities and primary care groups should re-examine their purchasing intentions, service reviews, and monitoring arrangements in the light of these findings.
Key messages
- A major reorganisation of cancer services is under way in England and Wales with the aim of improving access to and quality of treatment
- Residents with cancers of the bowel, lung, or breast in deprived areas in the Thames region were more likely to be admitted as emergencies and ordinary inpatients than their counterparts from more affluent areas, and patients with lung or breast cancers from deprived areas were less likely to receive surgical treatment
- Patients with colorectal cancer from the most deprived areas were less likely to be seen at hospitals with a large caseload than were patients from affluent areas; the opposite held true for patients with breast cancer, but no association was found for admissions for lung cancer
- More effective early diagnostic and referral procedures in primary care in deprived areas are required if reductions in mortality are to be achieved
- Hospital mergers and plans for service reconfiguration and bed closures must take into account inequities in access to treatment among residents in deprived areas

OBJECTIVE--To determine the level of knowledge of emergency contraception among 14 and 15 year olds. DESIGN--Confidential questionnaire survey. SETTING--10 secondary schools in Lothian, south east Scotland. SUBJECTS--1206 pupils predominantly (98.7%) aged 14 and 15 in the fourth year of secondary school. MAIN OUTCOME MEASURES--Knowledge of the existence of emergency contraception; of its safety, efficacy, and time limits; and of where to obtain it. RESULTS--1121 (93.0%) fourth year pupils aged 14-16 had heard of emergency contraception. 194 girls (32.7%) and 168 boys (27.5%) had experienced sexual intercourse. Of girls who had experienced sexual intercourse, 61 (31.4%) had used emergency contraception. Knowledge of correct time limits was poor, sexually active girls being the most knowledgeable. Pupils attending schools ranked lower than the national average for academic attainment were less likely to have heard of emergency contraception and more likely to have been sexually active. 861 (76.8%) pupils knew they could obtain emergency contraception from their doctor. 925 (82.5%) pupils believed emergency contraception to be effective but 398 (35.5%) thought it more dangerous than the oral contraceptive pill. CONCLUSIONS--One third of sexually active girls aged under 16 in Lothian have used emergency contraception. This may help explain the fairly constant teenage pregnancy rates despite increasing sexual activity. Scottish teenagers are well informed about the existence of emergency contraception. However, many do not know when and how to access it properly. Health education initiatives should target teenagers from less academic schools as they are more likely to be sexually active at a young age and are less well informed about emergency contraception. 相似文献

A total of 179 Tyneside children who had suffered at least one episode of wheeze since school entry were seen at the age of 7. All but 14 had visited a doctor for chest symptoms, but a diagnosis of asthma had been offered to the parents of only 21 children, including three of the 56 children experiencing four to 12 wheezy episodes a year and 11 of the 31 children experiencing more than 12 episodes a year. Bronchodilator treatment was rarely offered in the absence of such a diagnosis, and two thirds of the children had never received a bronchodilator. Of the children experiencing four or more episodes a year, only a third had received bronchodilator drugs regularly, though half had lost more than 50 days from school because of wheeze. School absenteeism fell 10-fold in the 31 children finally offered continuous prophylactic treatment. Although many doctors had feared that use of the word "asthma" would cause anxiety, parents were uniformly relieved when given an explanation of their child''s recurrent wheeze. This study uncovered a disturbing amount of ill health in children that was easily rectified. Probably this same problem exists in other areas. 相似文献
