[Four cases of Creutzfeldt-Jakob's disease (author's transl)]
Insights
Creutzfeldt-Jakob disease (CJD) is a rare, transmissible dementia with rapid progression. This report details four cases, highlighting clinical, pathological, and diagnostic features, and emphasizes safety precautions.
Area of Science:
- Neurology
- Pathology
- Infectious Diseases
Background:
- Creutzfeldt-Jakob disease (CJD) is a rare, fatal neurodegenerative disorder characterized by rapid cognitive decline.
- This report presents a detailed clinico-pathological analysis of four CJD cases.
Observation:
- Patient ages ranged from 54 to 81 years, with disease courses lasting 1-4 months post-symptom onset.
- Clinical manifestations included severe mental deterioration, amnesia, aphasia, apraxia, progressive rigidity, and myoclonus.
- Electroencephalogram (EEG) revealed characteristic 1/sec pseudorithmic spikes.
Findings:
- Histopathological examination showed significant astrocytosis in the cerebral cortex, status spongiosus, and neuronal loss, predominantly in parieto-occipital lobes.
- Diagnostic criteria for CJD were reviewed based on these findings.
Implications:
- The study underscores the importance of strict safety protocols when handling biological, bioptic, and autoptic specimens to prevent accidental transmission.
- Establishing a national registry in Italy is crucial for monitoring CJD incidence and spread.
Abstract:
The clinico-pathological features of 4 cases of Creutzfeldt-Jakob disease, a transmissible virus dementia, are reported. The onset of the disease varied between 54 and 81 years of age: the course is dramatic and the demise occurs 1-4 months after the onset of symptoms. The clinical picture includes mental deterioration with amnesia, aphasia, apraxia and neurologic symptoms, mainly consisting in progressive rigidity and myoclonus. All cases show the typical 1/sec pseudorithmic spikes on EEG. Histological changes include severe astrocytosis of the cerebral cortex, status spongiosus and mild neuronal loss. The changes are more marked in the parieto-occipital lobes. Criteria of clinical and pathological diagnosis are reviewed. The precautions to be taken in handling biological as well as bioptic and autoptic specimens are emphasized, in order to avoid accidental transmission of the disease. It seems essential to institute a register of cases of Creutzfeldt-Jakob disease in Italy to assess the incidence and diffusion of the disease in our country.
