Non-phenylketonuria hyperphenylalaninaemia in Northern Ireland: frequent mutation allows screening and early diagnosis.

Up to 10% of newborn children with a positive Guthrie test have non-phenylketonuria hyperphenylalaninaemia, i.e., mild elevation of serum phenylalanine that does not require dietary treatment. Depending on the relative frequencies of different phenylalanine hydroxylase mutations in a particular population, non-PKU HPA is usually caused by the combined effect of a mild HPA mutation and a severe PKU mutation. Presented here is a comprehensive analysis of non-PKU HPA in Northern Ireland. Of particular interest is one prevalent HPA mutation (T380M), which is present in over 70% of non-PKU HPA patients in Northern Ireland. Screening for this mutation is easy and inexpensive and can help confirm the diagnosis of non-PKU hyperphenylalaninaemia in the majority of cases at a very early stage. This may be clinically useful and reassuring for the parents. Other mutations described are V245A, L194P, and E390G.

Cross-infection control in dental practice in the Republic of Ireland.

OBJECTIVE: The purpose of this study was to examine the infection control procedures used in general dental practices in the Republic of Ireland. DESIGN: Postal survey. SETTING: The Republic of Ireland. PARTICIPANTS: 250 general dental practices. METHODS: Postal questionnaire. MAIN OUTCOME MEASURES: Use of infection control procedures; gloves, masks, sterilisation of instruments, staff training. RESULTS: A 74% response rate (n = 177), with 162 wearing gloves for all patients, 97% of whom used latex gloves. Routine glove use by 69% of dental nurses. Approximately one third of respondents complained of hand skin irritation attributed to the wearing of latex gloves. Routine mask wearing during treatment was reported by 68% of respondents. The method of choice for sterilising instruments was the steam autoclave for 97%. Time spent on surgery cleaning between patients was less than one minute in 12 per cent of practices. CONCLUSIONS: Cross-infection control procedures practiced by a high proportion of the respondents to the survey conform to guidelines suggested by various authorities. Further education may be appropriate in a number of areas such as mask wearing and the need to change gloves between patients.

Serological evidence of Hantavirus disease in Northern Ireland.

Since, to our knowledge, no clinically documented cases of haemorrhagic fever with renal syndrome (HFRS) have been reported in Northern Ireland, a sero-epidemiological study was carried out to assess the degree of Hantavirus immunity in a group of 627 Northern Irish patients presenting with symptoms suggestive of HFRS and 100 healthy controls. IFA screening for IgG Hantavirus specific antibodies was carried out with a panel of up to 9 different Hantaviral antigens. IgM screening was performed using a commercially available mu-capture ELISA based upon two recombinant Hantaviral nucleocapsid antigens. A seropositivity of 2.1% (15/727) was recorded, with an almost exclusive reaction against a rat-derived R22VP30 strain of the Seoul serotype. Sole reliance upon non-rat-derived classic screening antigens Hantaan (HTN 76-118) and Puumala (CG 18-20) would have resulted in the detection of only 2/15 (13.3%) of cases in IgG IFA, and 8/14 (57.1%) of the cases in IgG ELISA. The findings indicate that for the first time in Europe, and more specifically in N. Ireland, non-laboratory outbreaks of HFRS may be caused by wild rats acting as a reservoir for a Seoul-like Hantavirus. Conventional Hantavirus serology using Hantaan and Puumala as screening antigens does not appear sufficient for the detection of such cases of HFRS. Hence, we propose the addition of a rat derived Hantaviral antigen to the antigen screening panel as a means of improving the specificity of the detection methods.

Regional variation in the prescribing for diabetes and use of secondary preventative therapies in Ireland.

PURPOSE: To compare the prescribing of secondary preventative therapies for patients with both insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) in the eight health board regions of Ireland. METHODS: We utilized data from the national general medical services (GMS) prescribing database to examine the variability of prescribing for diabetes and associated secondary therapies between regions in those aged 45 years or more. Age-sex standardized prescribing rates of six secondary preventative therapies (aspirin, beta-blockers, statins, ACE inhibitors, angiotensin receptor (AT2) antagonists, and fibrates) were calculated for each region. RESULTS: Variations exist between regions for treated NIDDM (1.5-fold) and IDDM (1.5-fold). Wide variations were observed between regions for prescribing of secondary preventative therapies with the highest variability observed for statin prescribing (1.5- to 1.6-fold) and for AT2 antagonist prescribing (2.0-fold) in NIDDM patients. In those with NIDDM, men were more likely to receive aspirin OR=1.26 (1.21--1.31), ACE inhibitors 1.14 (1.101.18), and fibrates OR=1.55 (1.23--1.96) than women and those aged over 75 years were less likely to receive statins OR=0.60 (0.56--0.65) and fibrates OR=0.25 (0.17--0.37) than those aged 45--74. Similar results were also shown for patients with IDDM. CONCLUSIONS: The results suggest that access to secondary preventative therapy in diabetes patients is not equitable across regions, gender, and age in Ireland. While much of the variability remains unexplained, it may be due to differences in screening and health promotion between regions, prescriber uncertainty, variability in clinical need, or may be derived from a socioeconomic disparity among regions.

Effects of a monetary incentive on primary care prescribing in Ireland: changes in prescribing patterns in one health board 1990-1995.

BACKGROUND: In an attempt to curb the rapidly rising costs of primary care prescribing in Ireland, the government introduced a financial incentive scheme in 1993, to encourage general practitioners to restrain their prescribing. PURPOSE: To investigate the effects of a financial incentive scheme on GP prescribing in Ireland on prescribing costs and volume, and on some specific therapeutic areas. METHODS: Prescribing for 3 years before (1990-1992) and 3 years (1993-1995) after the introduction of incentives, based on a defined cohort of 233 general practitioners in the area of one health board. GPs were divided into tertiles based on their performance against their prescribing budgets into 'savers' (generally underspent and received incentive payments), modest overspenders and large overspenders. RESULTS: Savers were always lower cost prescribers than the other groups. They contained their rate and costs of prescribing in contrast to the other groups, e.g. percentage rise in prescribing costs in the year after the introduction of the scheme -7.9%, +1.2% and +7.3% respectively, (P < 0.05) for savers, modest overspenders and large overspenders respectively. This effect was short lived however and was gone by the third year of the study. CONCLUSIONS: The financial incentives had a marked effect on prescribing volume and cost on some practices who could achieve targets and hence incentive payments. The incentives had little effect on high spending practices. Such incentive schemes need careful evaluation if they are not to become perverse to the good health of patients.

Uptake of COX-2 selective inhibitors and influence on NSAID prescribing in Northern Ireland.

PURPOSE: Rofecoxib and celecoxib have been recently introduced and promoted as 'safer' non-steroidal anti-inflammatory drugs (NSAIDs) regarding gastric toxicity. The primary aim was to measure their uptake and any impact on conventional NSAID prescribing. A secondary aim was to assess any change in proton pump inhibitor (PPI) prescribing. METHODS: Prescribing data in terms of defined daily doses (DDDs) were pooled from 1997 onwards. Linear trends in the data were tested for using regression analyses. Direct comparisons were made between the April-June quarter of the year 1999 (i.e. before the introduction of rofecoxib and celecoxib) and the same quarter 3 years later. RESULTS: Overall NSAID prescribing in Northern Ireland was found to be increasing linearly at an estimated rate of 154,000 DDDs per quarter since the introduction of celecoxib and rofecoxib. The rate of increase in the volume of prescribing of the two new drugs was found to be four times the rate of decrease in prescribing of the 'older' NSAIDs. Overall prescribing of anti-inflammatory agents had increased from 37.8 to 47.7 DDDs/1000 patients/day over 3 years with no effect on the upward trend in PPI prescribing. CONCLUSIONS: The introduction of rofecoxib and celecoxib has increased prescribing volume of anti-inflammatory agents by 26% in Northern Ireland over the 3-year period. This could pose safety problems in the future as more people are being prescribed anti-inflammatory agents.

Idiopathic interstitial pneumonitis in children: a national survey in the United Kingdom and Ireland.

Interstitial lung disease (ILD) of unknown etiology in immunocompetent patients is rare in children. A national survey was carried out in the United Kingdom and Ireland over a 3-year period in order to identify prevalence, age distribution, histopathology, natural history of the illness, and response to current treatment.Forty-six cases were identified, including 29 males and 17 females. Seventy-six percent presented in the first year of life. Nine (16%) occurred within four families. Conventional treatment with pulsed methylprednisolone, prednisolone, or hydroxychloroquine, singly or in combination, resulted in an excellent response in 65% of cases. Seven children died (15%). The recurrence risk for further children within the same family to develop ILD is estimated to be approximately 10%. The prevalence rate of this condition in the United Kingdom and Ireland during the period of study for children aged 0-16 years is estimated to be 3.6 cases/million.

The molecular epidemiology of human immunodeficiency virus type 1 in six cities in Britain and Ireland.

We have sequenced the p17 coding regions of the gag gene from 211 patients infected either through injecting drug use (IDU) or by sexual intercourse between men from six cities in Scotland, N. England, N. Ireland, and the Republic of Ireland. All sequences were of subtype B. Phylogenetic analysis revealed substantial heterogeneity in the sequences from homosexual men. In contrast, sequence from over 80% of IDUs formed a relatively tight cluster, distinct both from those of published isolates and of the gay men. There was no large-scale clustering of sequences by city in either risk group, although a number of close associations between pairs of individuals were observed. From the known date of the HIV-1 epidemic among IDUs in Edinburgh, the rate of sequence divergence at synonymous sites is estimated to be about 0.8%. On this basis we estimate the date of divergence of the sequences among homosexual men to be about 1975, which may correspond to the origin of the B subtype epidemic.

Surgery for neonatal necrotising enterocolitis in Ireland 1980-1985.

Forty-seven infants were operated on for necrotising enterocolitis (NEC) in Ireland in a 6-year-period from 1980 to 1985. Incidence for surgical NEC in Ireland is 1/8733 live births. 44/47 patients were operated on during the acute phase and 3 patients had elective resection of strictures following conservative management. Indication for surgery in the acute phase was pneumoperitoneum in 37 infants. The initial procedure was: drainage alone in 10 patients, laparotomy and defunctioning enterostomy in 18, resection of the necrotic segment and proximal enterostomy in 15. 27/44 acute patients survived giving an overall mortality of 38.6% for acute NEC but mortality directly related to NEC was 31.8%. There was an inverse relationship between mortality and age at surgery. Medical treatment included total parenteral nutrition (TPN) in all patients for a mean time of 20.5 days.

Mental illness in Northern Ireland. A comparison with Scotland and England.

First and all admissions to psychiatric hospitals and units during 1981 were obtained from the DHSS in England, Scotland and Northern Ireland. Age and sex standardized rates were calculated for each country. Possible reasons for observed rate differences are discussed. Whilst overall high rates of admissions in Northern Ireland are most likely attributable to provision and use of beds, these factors may not entirely account for high rates of admissions for neurotic disorder, particularly among males.

The incidence and prevalence of schizophrenia in the Republic of Ireland.

For the last century scientists have attempted to demonstrate high rates of insanity among the Irish. Recent prevalence studies of schizophrenia claim that there is indeed a greater number of cases in the west of Ireland than in other parts of the world. Cultural and genetic hypotheses have been advanced to explain these figures without a critical examination of the studies at the basis of this claim. The relevant underlying research and the resulting hypotheses are reviewed to show that their conclusions are equivocal and ungeneralizable. This is most often due to the method of case collection and inconclusive cross-cultural comparisons. It is hoped that Ireland will not henceforth be considered a high prevalence area for schizophrenia without more reliable research in this topic.

Sexual behavior and attitudes of university students in Northern Ireland.

Two surveys of a Northern Ireland student sample were conducted in 1987 and 1988. A total of 419 female and 201 male subjects completed self-administered anonymous questionnaires concerning their behavior, knowledge, and attitudes towards sex, AIDS, homosexuality, contraception, and relationships. Results indicated a relatively low level of sexual experience, and for those with experience, relatively few partners. The possible influences of gender and religiosity on sexual behavior and attitudes, in the context of Northern Ireland, are discussed. Subjects reported considerable variation in the amount of sex education, but the majority received little or none. This student sample held relatively conservative attitudes towards love, sex, and marriage and this was particularly true for females and for regular churchgoers. In addition, attitudes towards homosexuality were negative (particularly among regular churchgoers). Attitudes towards contraception were more positive than expected among Catholic subjects, and few indicated that they would refuse to use contraceptives on principle. Responses to items about AIDS were highly uniform, suggesting that much of the information made available to the public has been absorbed. However, the lack of uniformity of response to more general items about sex, relationships, and contraception may indicate that fundamental changes in sexual behavior are unlikely to be brought about by influencing a rather narrowly defined set of attitudes about AIDS.

Invasive Haemophilus influenzae in the Republic of Ireland.

Prior to the general availability of Haemophilus influenzae type b vaccine in the Republic of Ireland, a two-year study of the epidemiology of invasive Haemophilus influenzae disease was carried out. Of 137 invasive strains of Haemophilus influenzae examined in a central laboratory, 94.2% were serotype b and 90.5% were biotype I. Seventeen percent of serotype b strains produced beta-lactamase, and 2.3% were resistant to both ampicillin and chloramphenicol. The majority of serotype b strains were electrophoretic types of the electrophoretic 12 clone family, principally 12.5. Meningitis was the most common infection caused by serotype b. The study data extend the current knowledge of strains of Haemophilus influenzae causing invasive disease in the Republic of Ireland.

Ethical approval for national studies in Ireland: an illustration of current challenges.

BACKGROUND: Ethical approval of research projects is, appropriately, an essential prerequisite in health settings. AIMS: This paper outlines difficulties encountered with procedures for gaining ethical approval for two multicentre surveys in Ireland. METHODS: The experiences of two national surveys were documented. RESULTS: Delays in processing ethics applications led to substantial delays in both surveys. Research ethics committees (RECs) assessed applications in an idiosyncratic manner. CONCLUSION: In Ireland, there is currently no accepted mechanism for single location ethical approval for multicentre studies. Instead, they require separate approval from all participating centres. The challenges of this system of application to multiple committees are outlined in this paper, and possible solutions presented.

Emergency department post-coital contraception in Northern Ireland.

BACKGROUND: The granting of a licence to Levonelle as an emergency hormonal contraceptive in the Republic of Ireland may require accident and emergency (A&E) departments to formally provide such a service. This article outlines the experiences of a Northern Ireland A&E unit. AIMS: To examine the pattern of attendance of patients requesting emergency contraception at an A&E department and to assess if adequate standards of care are achieved. METHOD: Retrospective case note review of 100 patients attending the A&E department requesting emergency contraception. RESULTS: Sixty-one per cent of requests for emergency contraception were outside normal pharmacy opening hours. Seventy-seven per cent of these patients were less than 26 years old. Most (63%) attended within 24 hours of unprotected sexual intercourse. Forty-three per cent of the patients studied had used no contraception prior to this request. Recording of menstrual details and sexual behaviour as part of the consultation was variable. CONCLUSIONS: A&E departments receive requests for emergency hormonal contraception particularly from younger women (<25 years). A&E staff must have appropriate training and support to manage these consultations effectively.

Demonstration of the shorter flagellin (flaA) gene of urease-positive thermophilic Campylobacter isolated from the natural environment in Northern Ireland.

The PCR amplicons (about 1450 bp in length) of flaA gene fragments of 11 isolates of urease-positive thermophilic Campylobacter (UPTC) isolated from the natural environment not including wild birds in Northern Ireland were demonstrated to be shorter than those of C. jejuni 81116 and six isolates of C. jejuni and C. coli (about 1700 bp) isolated in Northern Ireland and Japan. When the nucleotide lengths of the possible open reading frame (ORF) of the flaA genes were determined, those from the 11 UPTC isolates were estimated to be 1464-1503 bp, and those from the six C. jejuni and C. coli isolates and C. jejuni 81116 strain to be 1716-1728 bp. Nucleotide sequence and deduced amino acid sequence alignments of the possible ORFs demonstrated that the ORFs from the 11 UPTC isolates lack about 80 amino acid residues, mainly from the approximate residue numbers 390-470 of the large variable region in the flaA protein of the seven isolates of C. jejuni and C. coli, and do not have any internal termination codons. High amino acid sequence similarity of both amino- and carboxy-termini of the ORFs of the flaA gene was demonstrated between the 11 isolates of UPTC and the 7 isolates of C. jejuni and C. coli. The 11 UPTC isolates examined were strongly suggested to possess a shorter flaA gene without any internal termination codons.

Increased ampicillin resistance in Haemophilus influenzae in Northern Ireland hospitals.

Twenty-nine of one hundred and ninety-three (15%) clinical isolates of Haemophilus influenzae from Northern Ireland hospitals during 1985-1986 were found to be ampicillin resistant. This is twice the national average for the same period and 65% increase since a similar report in Northern Ireland three years previously. Computerised monitoring of routine specimens has shown this resistance level to be maintained in 1989. Susceptibility to other antimicrobials is discussed.
