Two hundred and twelve patients with clinically evidenced encephalomyelitis disseminata (ED), hospitalized in a neurological hospital, were observed with regard to psychopathological characteristics and cognitive changes in conformity with ICD-10 diagnostic criteria. The basis of this investigation was a standardized psychiatric interview. The age of the patients averaged 47 years whereas the duration of the disease averaged 14.3 years. 83.5% of the patients had a disease history of more than 6 years. The medium range of EDSS scores was 5.95%, the BPRS 36.7%. In 5.2% of the patients the course of ED was primarily chronic-progressive while 48% suffered from the intermittent, incomplete-reversible form: 47.6% developed secondary chronic-progressive symptoms. 18 psychopathological symptoms could be identified, the main symptom was depressive mood (49%), followed by impairment of affective sensitivity (34.9%) and affective instability/incontinence (31.1%). The most prevalent diagnoses were dementia (23.1%), organic personality disorder (18.5%), mild cognitive impairment (9%), and depressive disorder (7.6%) Only 33.5% were psychopathologically unaffected. The duration of the disease in all demented patients exceeded 6 years. Patients with an organic personality disorder showed a marked increase in the later stages of their illness in contrast to patients suffering from depressive disorder. At the beginning of ED, a highly significant (p < 0.0001) impairment of vision was found in all psychiatric patients. Dementia patients and organic personality patients, on the other hand, showed an advanced degree of ataxia. Actually, there was a considerably lesser incidence of pareses in the non-psychopathological group whereas ataxia was significantly more prevalent in the three cognitively impaired ED-subgroups than in the control group. These findings set the stage for constructive discussions, taking due consideration of existing research results on ED with particular reference to the implications regarding future research as well as the clinical therapy of patients.

Mucolipidosis II (ML II), also called I-cell disease, is a unique lysosomal storage disease caused by deficient activity of the enzyme N-acetylglucosamine-1-phosphotransferase, which leads to a failure to internalize enzymes into lysosomes. We report on a colony of domestic shorthair cats with ML II that was established from a half-sibling male of an affected cat. Ten male and 9 female kittens out of 89 kittens in 26 litters born to clinically normal parents were affected; this is consistent with an autosomal recessive mode of inheritance. The activities of three lysosomal enzymes from affected kittens, compared to normal adult control cats, were high in serum (11-73 times normal) but low in cultured fibroblasts (9-56% of normal range) that contained inclusion bodies (I-cells), reflecting the unique enzyme defect in ML II. Serum lysosomal enzyme activities of adult obligate carriers were intermediate between normal and affected values. Clinical features in affected kittens were observed from birth and included failure to thrive, behavioral dullness, facial dysmorphia, and ataxia. Radiographic lesions included metaphyseal flaring, radial bowing, joint laxity, and vertebral fusion. In contrast to human ML II, diffuse retinal degeneration leading to blindness by 4 months of age was seen in affected kittens. All clinical signs were progressive and euthanasia or death invariably occurred within the first few days to 7 months of life, often due to upper respiratory disease or cardiac failure. The clinical and radiographic features, lysosomal enzyme activities, and mode of inheritance are homologous with ML II in humans. Feline ML II is currently the only animal model in which to study the pathogenesis of and therapeutic interventions for this unique storage disease.

The study covered 52 women, aged 19-30 years, who had previously taken home-made poppy preparations. In seven of them we diagnosed opium use (F 11.11 according to ICD-10) and 45 had opium abuse (F 11.21). All were detained in penitentiaries for 2-23 months. The control group consisted of 20 healthy females. A significant frequency of brain stem and extrapyramidal disturbances was found in the opium abuse group. Brain stem signs included tendon anisoreflexia (100-2%), nystagmus (87 5%), ataxia (87 5%) and corneal hyporeflexia (48 7%). Among the most frequent extrapyramidal disturbances were a positive pushing test (90 4%); test with pendular swinging of the legs (85 5%) and hand tremor (82 7%). Statistical analysis revealed a relationship between the degree of extrapyramidal system damage and duration of opiate dependence.
