Four patients with Whipple's disease which had responded to antibiotic therapy, later developed neurologic disease identical to that seen in patients with Whipple's disease who died without treatment. Dementia, myoclonus, ataxia, and supranuclear ophthalmoplegia were the main neurologic features. Restarting antibiotics has been followed by stabilization of disease in all four. Two have improved. In three, the previously diagnosed and treated Whipple's disease was not considered as a possible cause of the neurologic disease until the symptoms and signs were far advanced. It is advisable to periodically evaluate all patients with Whipple's disease, even after successful treatment. Signs of neurologic disease should be considered a possible recurrence of Whipple's disease and antibiotics restarted.

A familial disorder was characterized by chorea, ataxia, myoclonus, convulsions, dementia, and mental retardation. In five cases, the main lesion affected cerebellar dentate nuclei, with nerve cell loss, gliosis, chromatolysis, and grumose degeneration. Fibrous glial cell proliferation was detected in the globus pallidus.

This study reviews 99 anatomically verified case of Lafora body disease (82 from the literature and 17 personal cases). The clinical symptoms of the disease are characterised by the triad; epilepsy, myoclonus and dementia. An anatomical and histochemical study has been undertaken and as a result emphasis is given to recent hypotheses that suggest there are similarities with Type IV glycogen storage disease (Andersen's disease) which, although clinically distinct, has the same enzyme defect.

Two patients had an illness characterized by a positive family history, juvenile onset, macular cherry-red spots, myoclonus, generalized convulsions, and cerebellar ataxia. Neither had dementia, gargoyle facies, bone or joint deformities, or visceromegaly. Vacuolated lymphocytes were not seen in the peripheral blood or bone marrow. Specimens from the rectum and vermiform appendix showed Sudan black B-, Sudan III-, and PAS-positive granules within the neurons of the myenteric plexus. On electron microscopic examination, lysosome-like bodies, membranous cytoplasmic bodies, pleomorphic lamellated bodies, dense bodies, and lipofuscin-like bodies in the neurons were seen, with a suggestion of morphological transitional forms among them. Sialoglycopeptides, especially sialic acid, were increased in the urine, but excretion of acid mucopolysaccharides was normal. Assays of lysosomal enzymes in leucocytes showed normal enzymatic activity. On the basis of the clinical, biochemical, and histological results, we suggest that these two cases and four similar cases reported in the literature be classified differently from the previously described lipidoses, although it is not known whether these cases represent a new entity or merely a clinical variant of juvenile lipidosis.

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.

We present two patients aged 66 and 69, with a rapidly progressive disease (10 and 15 months' duration) in which the presenting symptom was instability of gait. Later dementia was also a prominent feature. One case had myoclonus. Repeated EEGs showed symmetrical slowing in one case and periodic generalised bursts of triphasic waves at 1 cps superimposed upon a slow (3-4 cps) background activity in the other. The pathological findings consisted of classical Creutzfeld-Jakob disease (CJD), Kuru plaques (KP) were disseminated in the brain, but were more numerous in the cerebellum, putamen and thalamus. Neurons with large vacuoles in the cytoplasm were numerous in the putamen, thalamus and anterior horns. Stress is laid upon the common findings in both CJD and Kuru (K) (clinical features, pathological data, lack of antibody response, transmissibility, change in pattern on transmission). The possibility of a common origin of the two diseases is discussed.

One hundred twenty-four consecutive cases of Creutzfeldt-Jakob disease (CJD) in France, verified by biopsy or autopsy between 1968 and 1977, were analyzed with respect to their clinical characteristics. The series comprised equal numbers of men and women, with the most frequent age at onset being 60 to 64 years and the most frequent duration, two to three months. A prodromal illness was observed in more than one-third of the patients. Clinical presentations and symptom frequencies are tabulated, and a multifactor analysis has been performed to obtain those combinations of symptoms and signs which occurred at least as often as the triad of dementia, myoclonus, and a positive electroencephalogram. Two groups of atypical cases are also emphasized: one with sudden, strokelike presentation and rapidly evolving illness of less than 2 months' duration, and the other with a long clinical course of between 2 and 10 years.

An extrapyramidal disorder occurring in three generations of a family (only males) is described The clinical features were progressive dementia and extrapyramidal signs without choreiform hyperkinesia. The youngest patient (onset of disease at the age of 22 years) showed tremor, rigidity, ataxia, convulsions, and myoclonus. The neuropathologic findings were characterized by isolated symmetrical degeneration of the corpus striatum and diffuse cortical atrophy without affecting other cerebrospinal neuronal systems. The clinical features of this familial disorder and its relation to other types of familial striatal degeneration and to the juvenile form of Huntington's chorea are discussed.

In five generations of Anglo-Saxon family W, 28 members were affected with dominant hereditary ataxia. In 1969, two members of this family were reported as prototypes of dominant spinopontine atrophy. We discuss two additional members of the original family, with one postmortem examination, including ultrastructual study. In contrast to previously accepted clinical generalizations, we found abolished tendon reflexes and flexion contractures of the lower extremities in patient 1 and onset of illness at the age of 18 years, palatal myoclonus, and optic atrophy in patient 2. Dementia was observed in both patients. Unlike in previous pathological reports, our patient 1 showed definite involvement of the cerebellum and mild degeneration of the inferior olivary nuclei. We conclude, therefore, that clinical and pathological distinction between dominant spinopontine atrophy and olivopontocerebellar atrophy is not clear and raises the question of the justification for regarding dominant spinopontine atrophy as a nosological entity.

Between September 1972 and January 1976 an outbreak of dialysis dementia affected 20 patients maintained by long-term hemodialysis. The clinical picture was characterized by an insidious onset of altered behaviour, dementia, speech disturbance, myoclonus, and convulsions. Nineteen patients died, but one patient has survived for 16 months. It was later established that in June 1972 the city had altered its method of water purification and that this resulted in higher water aluminum levels. The temporal relation between periods of high water-aluminum content and the appearance of new cases supports the view that aluminum may play a role in the causation of dialysis dementia.
