[Can emerging zoonoses be controlled?].

The report 'Emerging zoonoses' of the Health Council of the Netherlands was written on request from the Minister of Health, Welfare and Sport. It gives an expert view on how to anticipate zoonoses that could emerge in the near future by addressing questions regarding risk assessment, prevention, early detection, control and communication. Further emphasis in the report is given to developments within the European Union (EU). The report had to serve as the basis for a European policy conference on 16 and 17 September 2004 during the Dutch presidency of the EU. Some important developments announced by the Minister are: establishment of a National Centre for Infectious Diseases to advise the Minister and coordinate crisis control during outbreaks, measures to strengthen the regional structure of public health in the Netherlands, and a budget for the strengthening of public health research.

Influenza-associated encephalopathy: no evidence for neuroinvasion by influenza virus nor for reactivation of human herpesvirus 6 or 7.

During 2 consecutive influenza seasons we investigated the presence of influenza virus, human herpesvirus (HHV) type 6, and HHV-7 in cerebrospinal fluid samples from 9 white children suffering from influenza-associated encephalopathy. We conclude that it is unlikely that neuroinvasion by influenza virus or reactivation of either HHV-6 or HHV-7 is involved.

[Dutch Institute for Health Care Improvement revised guideline, 'Sexually transmitted diseases and neonatal herpes'].

The Dutch Institute for Health Care Improvement revised guideline, 'Sexually transmitted diseases and neonatal herpes' summarises the current scientific position on the diagnosis and treatment of a great number of sexually transmitted diseases (STD) and neonatal herpes. Symptomatic treatment of suspected Chlamydia trachomatis infection and gonorrhoea without previous diagnosis is not recommended. Treatment can be started immediately, once samples have been taken. Risk groups eligible for screening or proactive testing on C. trachomatis infection include: partners of C. trachomatis-positive persons, visitors of STD clinics, women who will undergo an abortion, mothers of newborns with conjunctivitis or pneumonitis, young persons of Surinam or Antillean descent, young women with new relationships and individuals whose history indicates risky sexual behaviour. A period of 3 months can be adopted between a risky contact and the HIV test (this used to be 6 months), unless post-exposure prophylaxis was used. For the treatment of early syphilis no distinction is drawn between HIV-infected and non-HIV-infected persons. It is no longer recommended that women in labour with a history of genital herpes are tested for the herpes simplex virus. Virological testing of the neonate is only advised if the mother shows signs of genital herpes during delivery.

Chronic active Epstein-Barr virus infection in an adult with no detectable immune deficiency.

INTRODUCTION: Epstein-Barr virus (EBV) establishes lifelong latent infection. In some patients the host-virus balance is disturbed, resulting in a chronic active EBV infection. The following case illustrates the difficulty in diagnosing and treating chronic EBV infection. CASE: A 30-year-old woman was referred because of recurrent swellings of lymphatic tissue of both eyelids, orbit and lymph nodes and general malaise since the age of 19. In the past, repeated biopsies showed MALT lymphoma and nonspecific lymphoid infiltrations. Now, a biopsy of an axillary lymph node showed paracortical hyperplasia with a polymorphous polyclonal lymphoid proliferation, and large numbers of EBV-encoded small RNA (EBER) positive cells, consistent with EBV infection. Laboratory investigation showed a high EBV viral load. No evidence of immunodeficiency was found. Chronic active EBV infection (CAEBV) was diagnosed. Treatment with high-dose acyclovir did not significantly reduce the viral load. Rituximab was given in an attempt to reduce the amount of EBV-infected B lymphocytes. However, soon after the second dose the patient died of a sub-arachnoidal haemorrhage. CONCLUSION: This case report illustrates CAEBV as a rare manifestation of EBV-induced disease, which will be detected more frequently with the use of EBV-EBER hybridisation of lymph nodes and polymerase chain reaction (PCR) for EBV DNA. The prognosis is poor with no established therapeutic strategies.

Epidemiological survey of neonatal non-polio enterovirus infection in the Netherlands.

The epidemiological, virological, and clinical data of 119 infants less than 30 days of age with enteroviral infection collected from January 1993 to November 1995 by the diagnostic virology laboratories were analyzed retrospectively. Ninety-eight isolates (83%) were obtained in the period of May 1 to December 1 with a peak in the summer months. Sixty-five percent (n = 78) of neonates became ill within the first 2 weeks of life. Echoviruses and Coxsackie virus type B were isolated most frequently, in 77 (65%) and 29 (24%) infants, respectively. Diagnosis was made by viral isolation from stool, nasopharyngeal swab, cerebrospinal fluid, and blood. One hundred four (87%) infants developed fever and 25 (21%) infants had diarrhea. A clinical diagnosis of sepsis was made in 42 (35%) infants and meningitis was diagnosed in 28 (24%) cases. The great majority of sepsis cases (36/86%) occurred in infants less than 15 days of age. In conclusion, non-polio enteroviruses (especially echoviruses) are a common and underreported cause of neonatal infection in the Netherlands in the summer months and are associated with a clinical diagnosis of sepsis or meningitis cases in the first 2 weeks of life in a high proportion of cases.

The pathogenesis of febrile seizures: is there a role for specific infections?

Although fever is regarded as the main trigger in the pathogenesis of febrile seizures (FS), it is not supposed to be the unique causative factor. In FS, there is a strong familial predisposition. This does not exclude infections as a causative factor because subtle genetic polymorphisms have been demonstrated to affect the course of infections. We review the literature on: (1) the role of fever, especially the height of temperature, its cause, and metabolic effects induced by temperature; (2) the role of heredity; (3) the role of cytokines which play a role in the induction of fever; and (4) the role of type of infection, with emphasis on newly identified agents and improved diagnostic techniques. With modern molecular techniques such as PCR, viruses have been detected in the CSF far more often than previously thought, even in the absence of pleocytosis of the CSF. This makes it difficult to distinguish FS from acute encephalitis. FS may be caused by neuroinvasion or intracerebral activation of viruses. Further studies should focus on these options because therapeutic intervention is possible and may prevent late sequelae such as recurrent FS and subsequent epilepsy.
