Epidemiology of Haemophilus influenzae type b invasive disease in Wales.

OBJECTIVE: To investigate the epidemiology of invasive disease due to Haemophilus influenzae type b, the clones responsible, and the antibiotic resistance of the isolates. DESIGN: Prospective population based analysis of clinical and epidemiological data collected for Gwynedd during 1980-90 and in the whole of Wales during 1988-90. SETTING: 19 hospitals in Wales; all medical microbiology laboratories in Wales participated. PATIENTS: 82 patients with confirmed invasive infections caused by H influenzae type b in Gwynedd during 1980-90 and 207 in Wales during 1988-90. MAIN OUTCOME MEASURES: Clinical and epidemiological measures; analysis of the clonal types of the isolates based on the electrophoretic mobilities of 17 metabolic enzymes; and antibiotic resistance. RESULTS: The annual incidence of H influenzae type b infections in Gwynedd was 3.2 cases/100,000 and in Wales was 2.5 cases/100,000. Most cases occurred in children aged under 5 years, the highest annual incidence being in those aged under 1 (84.6/100,000 and 56.9/100,000 in Wales). The cumulative risk of acquiring H influenzae type b disease by the fifth birthday was one in 456 in Gwynedd and one in 578 in Wales. Fifteen per cent of cases in Gwynedd and 7% of those in Wales occurred in adults. Predominant clinical conditions were meningitis in children and pneumonia in adults. In Gwynedd 2/70 (3%) children and 5/12 (42%) adults died. Long term neurological sequelae occurred in 8% (4/48) of children who survived haemophilus meningitis. Children presenting with infection were usually the youngest members of their family. No secondary household cases were identified. 100 of 128 (78%) strains were of a single clone, electrophoretic type 12.5, and 4/207 (1.9%) isolates from Wales were resistant to both ampicillin and chloramphenicol. CONCLUSIONS: The annual rate of infection in children aged under 5 in four Welsh counties was 12-44% higher than that previously published for the United Kingdom. The study emphasises the potential value of a vaccine effective in early infancy and provides baseline data to assess its efficacy after its introduction. Alternatives to ampicillin and chloramphenicol should be used as first line, empirical treatment for severe infections that might be caused by H influenzae type b in Wales.

A comparative review of gynecological day case surgery between England and Wales, France, and Germany.

A comparison was made of gynecological day case surgery between England and Wales, France, and Germany. Hospital In-Patient Enquiry statistics (1979-1985) as well as Department of Health statistics (after 1985) and the Audit Commission Reports (1990-1992) were used for England and Wales; the Baudelocque Hospital Audit (Paris) between 1985 and 1990 was used for France; the Niedersachsen Regional Audit between 1989 and 1990 was used for Germany. These are the only available statistics for all three countries. A retrospective analysis of these statistics of gynecological day case surgery produced estimates of its rate for common gynecological operations in the three countries. It showed that England and Wales performed significantly more (18 per cent) gynecological procedures as day cases than either France (less than 5 per cent) or Germany (11 per cent). Additional specific comparisons were made for certain procedures between England and Wales and France (TOP) and between England and Wales and Germany (D&C, laparoscopy, TOP, ERPC, and cone biopsy). day case surgery was performed in hospitals in England and Wales and in France whereas it was performed in freestanding units in specialists surgeries in Germany. Furthermore, there seemed to be a wide regional variation in the rate in England and Wales and in Germany. Waiting lists were significant in England and Wales and nonexistent in France and in Germany. However, medical unemployment was almost nonexistent in England and Wales whereas it was alarming in France and in Germany. The methods of financing of the health care systems appear to explain the intercountry variation.

The dental caries experience of 14-year-old children in England and Wales. Surveys co-ordinated by the British Association for the Study of Community Dentistry in 2002/2003.

OBJECTIVE: This paper reports the results of standardised clinical caries examinations of 77,693 14-year-old children from across England, Wales, Jersey and the Isle of Man. These 2002/3 coordinated surveys are the latest in a series which seeks to monitor the dental health of children and to assess the delivery of dental services. METHOD: The criteria and conventions of the British Association for the Study of Community Dentistry were used. Representative samples were drawn from participating health authorities and boards and caries was diagnosed at the caries into dentine (D3) threshold using a visual method without radiography or fibre-optic transillumination. RESULTS: These demonstrated, once again, a wide variation in prevalence across the area surveyed, with mean values for D3MFT for the current English government offices (of the National Health Service) and the local Health Boards in Wales ranging from 0.99 in the South East to 2.10 in Wales (2.41 in the Isle of Man). The mean value for across England and Wales was 1.48 (D3T=0.56, MT=0.10, FT=0.82). Overall 49 per cent of 14-year-old children in England and Wales had evidence of dentinal caries experience (D3MFT>0), the regional/country means ranged between 37 per cent (South-East) and) and 60 percent in Wales (65 per cent, Isle of Man). The mean D3MFT for those with disease at this threshold was 3.03. Trends over time demonstrate an improvement of 4% in overall D3MFT for England and Wales, there has been only small improvement in mean MT since 1994/95, while FT and care index have fallen. The number of fillings provided in 2002/3 and thus the care index, remains low, on average across England and Wales, only 55% of the dentinal caries experience identified by survey examinations of permanent teeth was seen as fillings (range in individual areas: 28% to 83%). CONCLUSION: These findings demonstrate a modest overall improvement in oral health, but a continuing need for more effective preventive strategies and treatment services for permanent teeth in this important age group. An average of half of the 14 year old children examined being affected by dentinal decay and a mean of three permanent teeth decayed into dentine for those children affected at this level of diagnosis is a poor start to charting oral health in the 21st Century in England and Wales.

Salmonella in pigs and animal feeding stuffs in England and Wales and in Denmark.

A comparison has been made between the incidence of salmonellas in pigs and feeding stuffs in England and Wales and in Denmark. In Denmark there is veterinary legislation requiring the sterilization of imported and home produced feed ingredients of animal origin. There is no such legislation in England and Wales. In Denmark 0.3% of resterilized imported meat and bone meal was contaminated with salmonellas. This compared with 23% of meat and bone meal in England and Wales and 20-27% of other ingredients of animal origin. In England and Wales salmonellas were isolated from 7% of caecal samples and 6% of lymph node samples, while in Denmark they were isolated from 3% of caecal samples and 4% of lymph node samples. In England and Wales 25 serotypes were found in both pigs and feeds and these included nearly all the most prevalent human pathogens. In Denmark four of the six serotypes in pigs had been found in resterilized feed. One notable difference between the two studies was the very wide range of serotypes found in pigs in England and Wales and the narrow range in Denmark. A second was that Salmonella typhimurium formed 15% of all Salmonella strains isolated from pigs in England and Wales, and 60% of those in Denmark.It is concluded that sterilization of animal raw ingredients in Denmark has reduced pig infections with types other than S. typhimurium that are found in England and Wales, but not with S. typhimurium. It is possible that this is because S. typhimurium once introduced into pigs is able to establish itself more easily than other serotypes.

Cancer incidence in England and Wales and New Zealand and in migrants between the two countries.

Risks of cancer incidence in people born in England and Wales and New Zealand (non-Maoris) living in their home countries, and after migration between the two countries, were analysed using data from their national cancer registries. Since these populations are of similar genetic origin, any real differences in cancer incidence between them are likely to reflect the action of environmental or behavioural risk factors. The greatest differences in risk between the countries were for cutaneous melanoma and lip cancer. In each sex, relative risks of these malignancies were 4 or greater for the New Zealand-born in New Zealand compared with English and Welsh natives in their home country, and risks for migrants in each direction were generally intermediate between those born in the home country in the two countries. Sizeable significantly raised risks in the New Zealand-born in New Zealand compared with English and Welsh natives in England and Wales also occurred for cancers of the mouth, small intestine, colon, thymus, eye and thyroid, and non-Hodgkin's lymphoma in each sex, and for cancer of the prostate. For all of these sites except mouth, small intestine and colon there were also risks around or above New Zealand-born levels for English and Welsh migrants to New Zealand; for colon cancer these migrants had risks close to those in England and Wales. New Zealand migrants to England and Wales had risks of cancers of the colon and prostate that were similar to or above New Zealand levels. Risks of cancers of the stomach, lung, pleura and bladder, and Hodgkin's disease in each sex, and cancers of the cervix, ovary and scrotum and penis, were substantially and significantly lower in the New Zealand-born living in New Zealand than in English and Welsh natives in England and Wales. In English and Welsh migrants to New Zealand risks of bladder cancer in each sex, and of scrotal and penile and pleural cancer in males, approximated to England and Wales risks; cervical cancer risk approximated to the New Zealand risk; and stomach, lung and ovarian cancers showed intermediate risks. Migrants from New Zealand to England and Wales did not gain the lung cancer or clearly the stomach cancer risk of their host country, but did have bladder cancer risks approximating to those in England and Wales.(ABSTRACT TRUNCATED AT 400 WORDS)

Control of hydatid disease in Wales.

OBJECTIVES: To evaluate the success of the south Powys hydatid control programme by analysis of trends in cystic disease in humans and sheep and dog infestation. DESIGN: A review of hospital admissions for human hydatid disease in 1984-90, abattoir prevalence surveys of hydatid cysts in adult sheep, arecoline acetarsol and coproantigen surveys of prevalence of Echinococcus infestation in dogs. SETTING: All hospitals in England and Wales, three abattoirs, and dog populations in mid ands south east Wales. SUBJECTS: Residents of England and Wales admitted to hospital between 1984 and 1990 with a new diagnosis of human hydatid disease (International Classification of Diseases (ICD), ninth revision, code 122) acquired in the United Kingdom. RESULTS: The average annual incidence of human hydatid disease in Powys, mid-Wales, fell from 3.9x10(-5) in 1974-83 to 2.3x10(-5) in 1984-90. Age specific incidence rates in Wales declined over this period only in children, and no cases occurred in children (<15 years) in Powys. Two Welsh children who lived in Gwent and mid-Glamorgan were infected. Prevalence of hydatid cysts in old sheep from south Wales declined during the control period, but in 1993 prevalence of cysts was 13%. Prevalence of E granulosus infestation was zero in the control area in 1993, but it was 2.4% in Powys dogs outside the control area in 1989 and 9.2% in dogs in Gwent in 1991. CONCLUSIONS: Human hydatid disease has been successfully controlled in south Powys but cystic echinococcosis is still endemic in sheep in mid-Wales, and there is a focus of infection in humans, sheep, and dogs in the bordering areas of Gwent and mid-Glamorgan. There is considerable potential for an upsurge in human cases if control measures are relaxed.
