The societal costs and quality of life of patients suffering from bipolar disorder in the Netherlands.

OBJECTIVE: To assess the societal costs and quality of life of patients suffering from bipolar disorder in the Netherlands. METHOD: Forty persons with a lifetime diagnosis of bipolar disorder (SCID/DSM-IV) and representative for the Dutch general population were interviewed to collect data on direct (use of medical resources) and indirect (productivity losses because of absence from work and reduced efficiency at work) costs of illness. Respondents' quality of life was also assessed. Prevalence (5.2%) of bipolar disorder was used to estimate total costs. RESULTS: Total costs of bipolar disorder were estimated at US 1.83 billion dollars (total direct costs = US 454 million dollars; total indirect costs = US 1.37 billion dollars). Participants' quality-of-life scores were lower than those of the general population. CONCLUSION: The societal costs form patients suffering of bipolar disorder in the Netherlands were high, especially the indirect costs because of absence from work. The quality of life of bipolar patients was lower than the general population.

Oral health care for nursing home residents in The Netherlands--a national survey.

In order to be able to develop adequate oral health care programs for nursing home residents in The Netherlands, currently available arrangements and problems experienced by dentists participating in this field of dentistry were evaluated in a national survey. One questionnaire was mailed to the managements of all nursing homes and a second to all dentists known to be involved in nursing home dentistry. The response rates were very high. The study indicated that, in almost every nursing home, dental care for residents was available, at least in cases of dental emergency. On average the dentists were spending only limited time on nursing home dentistry. The majority of dentists examined or treated the residents only when either the patients or others experienced or discovered an oral health problem. In delivering this kind of care the dentists experienced a lot of problems. These findings suggest that the oral health care for nursing home residents in The Netherlands must be evolved by research, special training of dentists, and through development of special care programs.

Blindness and partial sight due to retinopathy of prematurity in The Netherlands: 1975-1987.

In 1975-1987 at least 84 children developed blindness or impaired vision due to retinopathy of prematurity (ROP) in the Netherlands. Neonatal data were obtained on 74 (86%). Unexpectedly most children (40 i.e. 54%) had been in level I and II hospitals after birth. Screening for ROP had been either insufficient or not timed according to present recommendations in 33 out of 40 children in level I and II hospitals and 25 out of 34 in level III hospitals. As the number of children with ROP has not changed appreciably over the last 40 years, while birth rates in the Netherlands have steadily decreased, the incidence of blindness/impaired vision due to ROP has probably increased. In the current population at risk of ROP which differs considerably from the one during the first epidemic, the disease may not be completely preventable. We conclude that improvements in screening procedures and timely treatment are crucial in order to improve the present situation.

Antithrombotic drug prescription in atrial fibrillation and its rationale among general practitioners, internists and cardiologists in The Netherlands--The EXAMINE-AF study. A questionnaire survey.

The objective of the EXAMINE-AF study was to record and compare antithrombotic treatment in patients with atrial fibrillation (AF) in daily clinical practice of general practitioners, internists and cardiologists in the Netherlands. Eighty-six general practitioners, 93 internists and 99 cardiologists responded to postal questionnaires and enrolled 1596 patients: 365, 351 and 880 respectively. A cardiologist was indicated to be the main treating physician for AF in 82% of all patients; current antithrombotic treatment was initiated in 80% by a cardiologist. Of all patients, 84% were at high risk for stroke and therefore were eligible for oral anticoagulation treatment, but only 64% actually received this. Cardiologists instituted appropriate antithrombotic treatment best, compared with general practitioners and internists (70% vs. 58% and 55%; p < 0.001). Positive predictive factors for oral anticoagulation prescription were previous stroke/transient ischaemic attack (OR, 2.31; 95% CI, 1.33-4.02) and heart failure (OR, 1.72; 95% CI, 1.23-2.42). Contraindications for oral anticoagulation (OR, 0.46; 95% CI, 0.32-0.68), treatment by a general practitioner (OR, 0.29; 95% CI, 0.20-0.42) or internist (OR, 0.24; 95% CI, 0.15-0.39) were important factors for withholding treatment. Antithrombotic treatment in AF patients is well instituted in primary and secondary care in the Netherlands. Cardiologists play a key role in the diagnosis and management of the majority of AF patients, even in those regularly attending other physicians. Factors for oral anticoagulation prescription are heart failure, physician specialty and contraindications. Availability of guidelines seems instrumental for application of appropriate antithrombotic treatment.

Penicillinase-producing Neisseria gonorrhoeae in the Netherlands: epidemiology and genetic and molecular characterization of their plasmids.

Penicillinase-producing Neisseria gonorrhoeae strains were isolated in the Netherlands with increasing frequency during the period of 1976 to 1979. About 3% of the gonococci isolated in the first half of 1979 produced penicillinase. In contrast to the period of 1976 to 1977, most penicillinase-producing N. gonorrhoeae infections during the period of 1978 to 1979 were contracted in the Netherlands. The results of genetic and molecular studies on 80 penicillinase-producing N. gonorrhoeae strains were similar to earlier observations of others: resistance plasmids of only two sizes, 4.5 and 3.3 megadaltons (Md), occurred in penicillinase-producing N. gonorrhoeae strains, and these encoded for the TEM-1 enzyme. The 4.5-Md plasmid could be transferred to Escherichia coli when it coexisted with a plasmid of 24 Md. The latter plasmid was present in the vast majority of the strains carrying the 4.5-Md plasmid. One strain carried a cryptic 7.5-Md plasmid in addition to the commonly found 2.5-Md plasmid. Two penicillinase-producing strains of Haemophilus parainfluenzae isolated were found to carry a 3.3-Md plasmid species which was indistinguishable from the 3.3-Md gonococcal resistance plasmids. No plasmid deoxyribonucleic acid was found in two strains of penicillinase-producing Branhamella catarrhalis, and these strains produced a penicillinase different from the TEM-1 enzyme.

Longitudinal analysis of tick densities and Borrelia, Anaplasma, and Ehrlichia infections of Ixodes ricinus ticks in different habitat areas in The Netherlands.

From 2000 to 2004, ticks were collected by dragging a blanket in four habitat areas in The Netherlands: dunes, heather, forest, and a city park. Tick densities were calculated, and infection with Borrelia burgdorferi and Anaplasma and Ehrlichia species was investigated by reverse line blot analysis. The lowest tick density was observed in the heather area (1 to 8/100 m2). In the oak forest and city park, the tick densities ranged from 26 to 45/100 m2. The highest tick density was found in the dune area (139 to 551/100 m2). The infection rates varied significantly for the four study areas and years, ranging from 0.8 to 11. 5% for Borrelia spp. and 1 to 16% for Ehrlichia or Anaplasma (Ehrlichia/Anaplasma) spp. Borrelia infection rates were highest in the dunes, followed by the forest, the city park, and heather area. In contrast, Ehrlichia/Anaplasma was found most often in the forest and less often in the city park. The following Borrelia species were found: Borrelia sensu lato strains not identified to the species level (2.5%), B. afzelii (2.5%), B. valaisiana (0.9%), B. burgdorferi sensu stricto (0.13%), and B. garinii (0.13%). For Ehrlichia/Anaplasma species, Ehrlichia and Anaplasma spp. not identified to the species level (2.5%), Anaplasma schotti variant (3.5%), Anaplasma phagocytophilum variant (0.3%), and Ehrlichia canis (0.19%) were found. E. canis is reported for the first time in ticks in The Netherlands in this study. Borrelia lusitaniae, Ehrlichia chaffeensis, and the human granylocytic anaplasmosis agent were not detected. About 1.6% of the ticks were infected with both Borrelia and Ehrlichia/Anaplasma, which was higher than the frequency predicted from the individual infection rates, suggesting hosts with multiple infections or a possible selective advantage of coinfection.

Molecular detection of an importation of type 3 wild poliovirus into Canada from The Netherlands in 1993.

During the fall and winter of 1992-1993 an outbreak of wild poliovirus type 3-associated poliomyelitis involving 71 patients occurred in The Netherlands. Almost all of the individuals involved in the outbreak belonged to an orthodox religious denomination that prohibits vaccination. A surveillance was initiated to determine if there had been an importation of this same strain of wild poliovirus into a southern Alberta community with a similar religious affiliation. Viral culture of stool samples from consenting individuals in the community resulted in viral isolates which typed as poliovirus type 3. Sequencing of amplicons generated from both the 5' nontranslated region and the VP1/2A portion of the genomes from representative poliovirus isolates indicated a greater than 99% genetic similarity to the strain from The Netherlands. The results of this study show that the utilization of PCR-based diagnostics offers an important molecular tool for the concise and rapid surveillance of possible cases of wild poliovirus importation into communities with individuals at risk for infection.

Antigenic variation of the class I outer membrane protein in hyperendemic Neisseria meningitidis strains in the netherlands.

Since 1980, the number of cases of meningococcal disease caused by serogroup B isolates with the P1.4 serosubtype has greatly increased in The Netherlands. Screening for this serosubtype in the strain collection of The Netherlands Reference Laboratory for Bacterial Meningitis revealed that a low number of P1.4 strains had been present in the Dutch meningococcal population since 1965. Genotyping of P1.4 strains showed that one cluster of strains, the hyperendemic lineage III (D. A. Caugant et al., J. Infect. Dis. 162:867-874, 1990), is responsible for the increase since 1980. The diversity of the porA genes, which encode the P1 protein on which serosubtyping is based, was studied for genotypically different P1.4 strains and for lineage III strains expressing antigenically different P1 proteins. Sequence analysis showed that porA genes of genotypically distinct strains that express antigenically indistinguishable P1 proteins are identical only in the epitope-encoding region, suggesting that this region has spread through the meningococcal population via horizontal gene transfer. Analysis of porA genes of lineage III strains showed that both horizontal gene transfer and partial deletion of the epitope-encoding region may contribute to the different antigenic properties for P1 of these strains. Phase variation of expression of the porA gene seems to account for most nonreacting strains. These results show that serosubtyping may underestimate the rise of a hyperendemic clone.

Genotypic and phenotypic analysis of Borrelia burgdorferi isolates from The Netherlands.

Sixty-three Borrelia burgdorferi isolates recovered from Ixodes ricinus ticks collected in 17 locations in The Netherlands and three Dutch human skin isolates were characterized by rRNA gene restriction fragment length polymorphism, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and Western blotting (immunoblotting). All three human isolates belonged to B. burgdorferi group VS461. Of the tick isolates, 29 (46%) were B. burgdorferi sensu stricto, 2 (3%) were group VS461, 19 (30%) were Borrelia garinii, and 13 (21%) were different from any previously described genomic species. On the basis of the criteria described, 12 isolates formed a distinct genomic group, designated M19. rRNA gene restriction patterns of the group M19 isolates resembled but were not identical to the B. garinii patterns. Hybridization of digested DNA with a flagellin probe confirmed the separation of group M19 from the B. garinii isolates. One isolate, M63, was different from all the others. In conclusion, the occurrence of B. burgdorferi sensu stricto, B. garinii, and B. burgdorferi group VS461 in ticks from The Netherlands corresponds with the occurrence of these genomic species among tick isolates from other European countries. However, our findings suggest that B. burgdorferi sensu lato probably contains more than three genomic species.

High percentage of methicillin-resistant Staphylococcus aureus isolates with reduced susceptibility to glycopeptides in The Netherlands.

While testing the in vitro activities of 14 antimicrobial agents against 107 methicillin-susceptible Staphylococcus aureus (MSSA) and 250 methicillin-resistant S. aureus (MRSA) isolates collected in The Netherlands, we found to our surprise that 19 (7.6%) MRSA isolates were suspected of having reduced susceptibilities to the glycopeptides when the Etest system (AB Biodisk, Solna, Sweden) was used with a large inoculum (no. 2 McFarland standard) and an extended incubation time (48 h) on brain heart infusion agar for MIC testing. Eventually, 15 of these isolates were classified as heterogeneously resistant to glycopeptides (heterogeneously glycopeptide-intermediate S. aureus [hGISA] isolates) according to the population analysis profile-area under the curve analysis. The MICs at which 50 and 90% of isolates are inhibited obtained with the Etest system with the large inoculum were as follows: for MSSA isolates, 3.0 and 4.0 micro g/ml, respectively, for both teicoplanin and vancomycin; for MRSA isolates, 3.0 and 8.0 micro g/ml, respectively, for teicoplanin, and 3.0 and 4.0 micro g/ml, respectively, for vancomycin. This is the first report of hGISA isolates in The Netherlands.

Widespread dissemination in The Netherlands of the epidemic berlin methicillin-resistant Staphylococcus aureus clone with low-level resistance to oxacillin.

Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen and represents a growing public health burden due to the emergence and spread of epidemic strains, particularly within the hospital environment. An epidemic MRSA clone, with characteristic low-level resistance to oxacillin, emerged in the year 2000 and became endemic in the Netherlands. Multilocus sequence typing characterized the strain as sequence type 45, which was previously designated the Berlin epidemic MRSA clone. In 2 years, this strain has become the predominant MRSA clone in the Netherlands.

Increase in genetic diversity of Haemophilus influenzae serotype b (Hib) strains after introduction of Hib vaccination in The Netherlands.

Recently, there has been an increase in The Netherlands in the number of cases of invasive disease caused by Haemophilus influenzae serotype b (Hib). To study a possible change in the Hib population that could explain the rise in incidence, a multiple-locus variable number tandem repeats analysis (MLVA) was developed to genotype H. influenzae isolates. The MLVA enabled the differentiation of H. influenzae serotype b strains with higher discriminatory power than multilocus sequence typing (MLST). MLVA profiles of noncapsulated H. influenzae and H. influenzae serotype f strains were more heterogeneous than serotype b strains and were distinct from Hib, although some overlap occurred. The MLVA was used to genotype a collection of 520 H. influenzae serotype b strains isolated from patients in The Netherlands with invasive disease. The strains were collected from 1983 from 2002, covering a time period of 10 years before and 9 years after the introduction of the Hib vaccine in the Dutch national vaccination program. MLVA revealed a sharp increase in genetic diversity of Hib strains isolated from neonates to 4-year-old patients after 1993, when the Hib vaccine was introduced. Hib strains isolated from patients older than 4 years in age were genetically diverse, and no significant change in diversity was seen after the introduction of the vaccine. These observations suggest that after the introduction of the Hib vaccine young children no longer constitute the reservoir for Hib and that they are infected by adults carrying genetically diverse Hib strains.

Sudden infant death syndrome in child care settings in the Netherlands.

BACKGROUND: In the Netherlands, there is a very low incidence of sudden infant death syndrome (SIDS) due to effective preventive campaigns. METHODS: During the period September 1996 to August 2002, nationwide 161 deaths from SIDS (about 85% of all cases of SIDS during that time) were investigated by the Cot Death Committee of the Dutch Paediatric Association. RESULTS AND DISCUSSION: Over 10% of cases of SIDS took place during some type of child care. From a national survey carried out in 2000/01 information was available on the child care attendance of 2000 Dutch infants aged 3-6 months. Based on the hours usually spent in child care by these infants, the number of similarly aged infants that died from SIDS while attending child care was 4.2 times higher than expected. Remarkably, the prevalence of known risk factors for SIDS, such as sleeping position and parental smoking, was favourable in the SIDS cases in child care settings. The adherence of child care facilities to the safe sleeping recommendations is high in the Netherlands, and no explanation as to why child care settings may be associated with an increased risk of SIDS is apparent. The possibility of other explanations, such as stress and change in routine care, is hypothesised.

Epidemiology of pyridoxine dependent seizures in the Netherlands.

BACKGROUND: Pyridoxine dependent epilepsy is a rare cause of seizures in childhood. The diagnosis is made on clinical criteria, that in many cases are never met. Therefore, epidemiological data on pyridoxine dependency are scarce. AIMS: To study the epidemiology of pyridoxine dependent epilepsy in the Netherlands, and to determine whether the diagnosis is based on the appropriate criteria. METHODS: Nationwide all departments of paediatrics (n = 113) and of paediatric or neonatal neurology (n = 17) were asked to report cases of pyridoxine dependent seizures. Birth incidences were calculated using national data on live births from 1991 to 2003. RESULTS: Response was received from 67% of paediatric departments, including all university hospitals and 94% of child neurology departments. Thirteen patients were reported. Four definite (31%), three probable (23%), and four possible cases (31%) were identified. Two cases (15%) did not meet criteria for either of these groups. The birth incidence was 1:396,000 for definite and probable cases and 1:252,000 when possible cases are included. CONCLUSIONS: Thus far, epidemiological data on pyridoxine dependent seizures were only available from the UK and Ireland. A higher incidence was found in the Netherlands, in accordance with earlier suggestions of a regional difference. The study shows that the diagnosis is often made without performance of a formal trial of withdrawal. The importance of confirming the diagnosis, concerning the consequences as for individual prognosis, the potential side effects of prolonged pyridoxine substitution, and the possibility of treating the mother in case of future pregnancies are emphasised.

Epidemiology of neonatal group B streptococcal disease in the Netherlands before and after introduction of guidelines for prevention.

OBJECTIVES: (1) To describe the epidemiology of neonatal group B streptococcal (GBS) disease over five years (1997-2001) in the Netherlands, stratified for proven and probable sepsis and for very early (<12 h), late early (12 h - <7 days) and late (7-90 days) onset sepsis. (2) To evaluate the effect of the introduction in January 1999 of guidelines for prevention of early onset GBS disease based on risk factors. METHODS: Data on cases were collected in collaboration with the Dutch Paediatric Surveillance Unit and corrected for under-reporting by the capture-recapture technique. RESULTS: Total incidence of proven very early onset, late early onset and late onset GBS sepsis was 0.32, 0.11 and 0.14 per 1000 live births, respectively, and of probable very early onset, late early onset and late onset GBS sepsis was 1.10, 0.18 and 0.02 per 1000 live births, respectively. Maternal risk factors were absent in 46% of the proven early onset cases. Considerably more infants with proven GBS sepsis were boys. 64% of the infants with proven very early onset GBS sepsis were first born compared with 47% in the general population. After the introduction of guidelines the incidence of proven early onset sepsis decreased considerably from 0.54 per 1000 live births in 1997-8 to 0.36 per 1000 live births in 1999-2001. However, there was no decrease in the incidence of meningitis and the case fatality rate in the first week of life. The incidence of late onset sepsis also remained unchanged. CONCLUSION: After the introduction prevention guidelines based on risk factors there has been a limited decrease in the incidence of proven early onset GBS sepsis in the Netherlands. This study therefore recommends changing the Dutch GBS prevention guidelines.

Influences of ethnicity on perinatal and child mortality in the Netherlands.

AIMS: To investigate the differences in perinatal death and child mortality between different ethnic groups in the Netherlands. METHODS: Retrospective analysis of data collected between 1990 and 1993 in the national obstetric registry comprising 569 743 births. Retrospective analysis of all death certificates of 0 to 15 year old children routinely collected between 1979 and 1993, comprising 20 211 deaths. RESULTS: Black mothers had the highest perinatal death rate compared with indigenous Dutch mothers (odds ratio 2.2). Hindustanis (West Indian Asians) had an odds ratio of 1.4 and Mediterraneans 1.3. The increased rate for black and Hindustani women could be fully explained by preterm birth. In the Mediterranean group the differences were explained by teenage pregnancy, grand multiparity, and socioeconomic status rather than prematurity. The death rate of Turkish and Moroccan children was twice as high as that of native Dutch children. For the different diagnostic categories this was: infectious diseases, relative risk (RR) 2.2; hereditary (metabolic) disorders, RR 2.0; accidents and drowning, RR 1.9. One quarter of the Turkish and Moroccan children died while on holiday in their country of origin. Sudden infant death syndrome was twice as high for Turkish infants as for Dutch children and four times higher than for Moroccan infants. CONCLUSION: Ethnic minorities in the Netherlands have a higher perinatal and child mortality rate than the indigenous Dutch. Apart from socioeconomic differences, sociocultural and lifestyle factors play an important role.

Presumed ocular histoplasmosis in The Netherlands--an area without histoplasmosis.

AIMS/BACKGROUND: The syndrome of ocular histoplasmosis is usually prefaced by "presumed' as the aetiology is not yet clear. The aim of this study was to evaluate the clinical features of a similar ocular syndrome in the Netherlands where the fungus Histoplasma capsulatum is not endemic. METHODS: A retrospective multicentre study in which all patients were included who were diagnosed with a syndrome similar to presumed ocular histoplasmosis and in whom both fluorescein angiogram and all complete patient data were available. Fluorescein angiograms were examined by three authors in a masked fashion. Eighty one patients were selected who fulfilled the ophthalmic criteria for presumed ocular histoplasmosis. Fifty one patients showed the classic clinical picture, while 30 patients had an incomplete form as they did not show numerous histospots. RESULTS: No major difference in clinical characteristics could be identified when comparing the group of patients with the classic syndrome with the one with the incomplete syndrome. Final visual outcome of patients with macular subretinal neovascularisation after laser treatment was better when compared with untreated patients (p < 0.01). CONCLUSIONS: Since the fungus Histoplasma capsulatum is absent in the Netherlands, other aetiological agents must have led to this clinical entity similar to the presumed ocular histoplasmosis syndrome seen in the USA.

Euthanasia in The Netherlands.

The practice of euthanasia in the Netherlands is often used as an argument in debates outside the Netherlands--hence a clear description of the Dutch situation is important. This article summarises recent data and discusses conceptual issues and relevant characteristics of the system of health care. Special emphasis is put on regulation, including relevant data on notification and prosecution. Besides the practice of euthanasia the Dutch are confronted with the gaps in reporting of cases to the public prosecutor and the existence of cases of ending a life without an explicit request. Nevertheless, the "Dutch experiment" need not inevitably lead down the slippery slope because of the visibility and openness of this part of medical practice. This will lead to increased awareness, more safeguards, and improvement of medical decisions concerning the end of life.
