A 47-year-old woman was seen for progressive behavioural and cognitive disturbances slowly evolving over a 1-year period. Neuropsychological evaluation disclosed moderate to severe impairment of all cortical functions. Besides this no other clinical abnormality was found. MRI diffusion weighted imaging disclosed hyperintense cortical lesions in a ribbon-like fashion, with restricted diffusivity. EEG showed no periodic sharp waves and CSF examination was normal, including protein 14.3.3. She was heterozygote on codon 129. Her cognitive function continued to decline and she was readmitted for further investigation at the 24th month of disease. Again no ataxia or involuntary movements were observed. MRI disclosed widespread hyperintense lesions over the entire cortex and, for the first time, also caudato-putaminal hyperintensity in T2-weighted images. EEG again failed to show periodic activity. Stereotactic biopsy disclosed moderate spongiform changes, astrocytosis and perivacuolar staining with prion-directed antibodies. Western blot analysis revealed prion type 2 mobility pattern. We discuss the clinical significance of this case: as dementia was the sole finding, and this was slowly-evolving over a 2-year period, MRI findings were the key factor suggesting a prion disease in a woman that otherwise would probably be diagnosed with a primary degenerative dementia.

First probable case of vCJD reported in Portugal
Direcção de Serviços de Informação e Análise, Direcção-Geral da Saúde, Lisboa, Portugal
The Portuguese Direcção-Geral da Saúde (Directorate-Genearl for Health) was recently informed of the first probable case of variant Creutzfeldt-Jakob disease (vCJD) in Portugal, with laboratory evidence (tonsil biopsy) . The patient is 12 year old boy currently living with his parents and receiving specialist medical care. The case meets the European and Allied Countries Collaborative Study Group of CJD’s (EUROCJD) definition of probable vCJD (http://www.eurocjd.ed.ac.uk/def.htm) and has been confirmed by the United Kingdom’s National CJD Surveillance Unit. The patient does not have a history of travel to the United Kingdom.

We present the second variant Creutzfeldt–Jacob patient in the same district of northwest Portugal as was previously reported. A 14-year-old previously healthy girl had unexplained pain in the left leg, as well as psychiatric disturbances. This was shortly followed by progressive cognitive impairment, ataxia and generalised choreoatethosis. Neuropsychological assessment revealed severe frontal and medial temporal dysfunction, the posterior cortices being spared. An electroencephalogram was normal. CSF 14.3.3 protein was slightly positive. Magnetic resonance imaging showed the “hockey stick sign” and hyperintensities in the periaquedutal grey matter and in the right parietal cortex, the last with restriction to water molecule movement. SPECT revealed perfusion defects in the left frontotemporal and right parietal regions. PRNP gene sequencing showed no mutations, the patient being homozygous to methionine in codon 129. Five months after onset, immunocytochemical and immunoblotting analysis confirmed deposition of prion protein and a PrP4t electrophoretic pattern. The patient never travelled outside Portugal or received blood transfusions. She had surgical herniorrhaphy in 1998 (when catgut was used) and 2003. This is the second case in Portugal in a 2-year period and 20 km apart from each other, with no known common exposure apart from ingestion of cow meat. We discuss these case peculiarities and underline its epidemiological significance.

BSE: Scientists publish risk assessments for Costa Rica, Kenya, Slovenia and Romania
The Scientific Steering Committee (SSC) advising the European Commission on BSE related issues has today published its opinion on the Geographical Risk of Bovine Spongiform Encephalopathy (GBR) in Costa Rica, Kenya, Slovenia and Romania. The evaluation of the geographical risk of presence of BSE focuses on the risk for animals to incubate the disease. The Committee concludes that is highly unlikely that cattle infected with the BSE agent are present in domestic herds of Costa Rica (GBR level I). They found that this is unlikely but not excluded in the herds of Kenya and Slovenia (GBR level II) and that it is likely that BSE is present in the cattle herds of Romania (GBR level III) although this is not yet confirmed. Slovenia is the first accession country that is classified as GBR level II. All other accession countries evaluated so far have been classified at level III of Geographical BSE Risk. Similarly, all EU Member States are classified at level III except for Sweden, Finland and Austria (level II) and United Kingdom and Portugal (level IV).
The full text of the opinions is available at
The numbers of tested and positive cattle in each category in each EU Member State are published and updated regularly. Although the number of cases in the EU was increasing in 2001 and 2002, since 2003 the number of cases in the EU altogether is decreasing (EC, 2003; 2004). A total of over 10 million cattle were tested in the EU in 2004. Of these, 686 cattle were positive. Spain and Portugal were the only countries in the EU 15 Member States with an increase of cases in 2003, and Germany in 2004.

Background: Sporadic Creutzfeldt-Jakob disease (CJD) is a condition predominantly affecting older age groups, with cases aged less than 45 years rare and an age at onset or death of less than 20 years exceptional.
Methods: Data from the systematic study of sporadic CJD in the UK are available from 1970 onwards. Clinical and pathological data are reviewed in order to identify atypical cases, including those at the extremes of the age range of sporadic CJD. Detailed analysis of atypical cases is undertaken and in selected cases laboratory transmission studies are carried out in order to provide information on the characteristics of the infectious agent.
Results: In the UK two cases of sporadic CJD in adolescents have been identified, dying aged 16 and 20 years. The first case predated the epidemic of bovine spongiform encephalopathy and the characteristics of the second case, including laboratory transmission studies, are consistent with a diagnosis of sporadic rather than variant CJD.
Conclusion: The cases in this report indicate that sporadic CJD can develop at a very young age, that variant CJD is not the only form of CJD occurring in this age group and that neuropathological examination is essential to accurate diagnosis of human prion disease.
