One of the earliest Nazi efforts to create a super race was the mass sterilization of German citizens through radiation or surgery. A law enacted on July 14, 1933 stated that all patients suffering from hereditary mental disorders, schizophrenia, manic-depressive psychosis, hereditary epilepsy, chorea, blindness, deafness, other serious hereditary defects or alcoholism must be sterilized. Special courts were created. Directors of psychiatric institutions, certain doctors, as well as the patients themselves were called before the court. All medical personnel including nurses and midwives were to report anyone in their care who should be sterilized. Patients had the alternation of willingly committing themselves for life into a "closed" institution, where they would have no opportunity for heterosexual actifity. On the whole, German society did not support this law, particularly relatives and family of patients. From the sketchy records available, it is clear that there were often casualties and that patients were hunted out and forced to submit to sterilization.

Review of the literature concerning the relationship between deafness and psychiatric disorder reveals differences in the pattern of illness depending on the severity of deafness and the age of onset. In particular, the prevalence of schizophrenia in the prelingually deaf is similar to that found in the normal population, whereas the hard of hearing are over-represented among samples of patients suffering from paranoid psychoses in later life. Possible modes of action of long-standing hearing loss in the aetiology of paranoid illnesses are considered: the psychological and social consequences of deafness, the possible contribution of sensory deprivation phenomena, and the interference of hearing loss in attention, perception and communication. Finally, possible future lines of research are suggested.

A family is reported in which the mother and 4 of her 6 children are affected by a constellation of abnormalities including mental handicap, abnormal facies, short stature, soft fleshy hands with tapering fingers and skeletal abnormalities. The family is believed to represent a further group of individuals with Coffin-Lowry syndrome. Additionally, one affected daughter has symptoms suggestive of schizophrenia and one affected son has severe sensorineural deafness.

One hundred and one patients with late paraphrenia were examined using the Present State Examination. The established high prevalence rates of female gender, the unmarried state and sensory impairment were confirmed. All of the symptoms of schizophrenia, with the exception of formal thought disorder, were found in the subjects with approximately the same prevalence as reported in schizophrenics with a symptom onset in younger life. The presence of visual hallucinosis was significantly associated with visual impairment, but the same association was not found between auditory hallucinations and deafness. Mean age at onset of symptoms was high at 74.1 years. Using ICD-10 diagnostic criteria the patients were categorized as schizophrenia (61.4%), delusional disorder (30.7%) and schizoaffective disorder (7.9%). Patients in these diagnostic categories differed in their pre-morbid IQ estimations, current cognitive state measured by the Mini-Mental State Examination and in the number of scored positive psychotic PSE symptoms and their systematization of and preoccupation with delusions and hallucinations. There were no significant differences between the patients in the ICD-10 schizophrenia and delusional disorder groups in terms of age at symptom onset, sex ratio, response to treatment, being unmarried, the presence of insight or sensory impairment. The high degree of clinical similarity between patients with late paraphrenia combined with the inability of ICD-10 to define diagnostic subgroups that correspond to patient clusters derived from clinical symptoms or which are meaningfully different from each other in terms of demographic and prognostic factors provide a strong argument for the retention of late paraphrenia as the most appropriate diagnosis for such patients.

Eugenics, the attempt to improve the genetic quality of the human species by 'better breeding', developed as a worldwide movement between 1900 and 1940. It was particularly prominent in the United States, Britain and Germany, and in those countries was based on the then-new science of Mendelian genetics. Eugenicists developed research programs to determine the degree in which traits such as Huntington's chorea, blindness, deafness, mental retardation (feeblemindedness), intelligence, alcoholism, schizophrenia, manic depression, rebelliousness, nomadism, prostitution and feeble inhibition were genetically determined. Eugenicists were also active in the political arena, lobbying in the United States for immigration restriction and compulsory sterilization laws for those deemed genetically unfit; in Britain they lobbied for incarceration of genetically unfit and in Germany for sterilization and eventually euthanasia. In all these countries one of the major arguments was that of efficiency: that it was inefficient to allow genetic defects to be multiplied and then have to try and deal with the consequences of state care for the offspring. National socialists called genetically defective individuals 'useless eaters' and argued for sterilization or euthanasia on economic grounds. Similar arguments appeared in the United States and Britain as well. At the present time (1997) much research and publicity is being given to claims about a genetic basis for all the same behaviors (alcoholism, manic depression, etc.), again in an economic context--care for people with such diseases is costing too much. There is an important lesson to learn from the past: genetic arguments are put forward to mask the true--social and economic--causes of human behavioral defects.

Autopsy reports of patients with mitochondrial encephalopathy with lactic acidosis and strokelike episode (MELAS) are rare. This report documents the clinical and autopsy findings of a 47-year-old woman with MELAS syndrome. The diagnosis was corroborated by documenting a mitochondrial DNA mutation tRNA-Leu (UUR) at position 3243. The patient's clinical history was marked by schizophrenia, peptic ulcer disease, constipation requiring hemicolectomy, migraine headaches, deafness, and a left temporal lobe infarct. At autopsy, a muscle biopsy demonstrated numerous ragged red fibers and a partial cytochrome C oxidase deficiency. By electron microscopy, increased numbers of slightly hypertrophic mitochondria were observed focally within myocytes and vessel walls; paracrystalline mitochondrial inclusions were not seen. The brain at autopsy showed mild cerebral atrophy and diffuse cortical gliosis. Prominent bilateral basal ganglia calcifications and vascular sclerosis were present, and a small remote left temporal lobe infarct was seen.

In order to examine the effect of congenital or early acquired deafness on hallucinatory modalities in schizophrenia, we interviewed 67 prelingually deaf schizophrenic patients (using sign language) about their hallucinatory experiences over the entire course of their illness. We also analysed the clinical records of our subjects' previous hospitalizations. In our deaf sample, visual and tactile hallucinations were plainly over-represented as hallucinatory modalities in comparison with hearing schizophrenic samples. Although some patients reported visual hallucinatory perceptions of sign language messages, the hallucinatory reception of meaningful information in deaf patients seems also to remain affiliated to the 'auditory' modality. It was concluded that the different representation of hallucinatory modalities reflects in particular the influence of 'the deaf way' of sensory experience on imagery processes.

There have been many reports of musical hallucinations in deafness, organic brain disease and epilepsy, but few reports of their occurrence in schizophrenia. Musical hallucinations tend to be regarded as specific manifestations of deafness and organic brain disease rather than of schizophrenia. However, since schizophrenic musical hallucinations are less distressing to schizophrenic patients than verbal hallucinations and psychiatrists have little interest in them, they may be missed. We treated schizophrenic patients who experienced musical hallucinations and traced the symptomatic changes. They exhibited semeiological changes similar to the changes in verbal hallucinations. Musical hallucinations are clearly a symptom of schizophrenia. By reporting these cases, we encourage concern about this symptom, which may be missed when psychiatrists interview patients.

Chromosome 6 is probably best known for encoding the major histocompatibility complex (MHC) which is essential to the human immune response. In addition, it has been shown to be associated with many diseases such Schizophrenia, Diabetes, Arthritis, Haemochromatosis, Narcolepsy, Epilepsy, Retinitis Pigmentosa, Deafness, Ovarian Cancer, and many more. Chromosome 6 is about 180 Mb in size and is estimated to encode around 3500 genes of which only about 10% are currently known. It is our aim to map, sequence and annotate the entire chromosome in close collaboration with the chromosome 6 community.

There is a dearth of good mouse models for central nervous system (CNS) disorders. However, the development of gene-targeted technology and the recognition of the importance of the mouse as a model organism have led to the development of a range of behavioural tests for mice. Spontaneous mutations in mice have already provided important information about the role of novel gene products in disorders such as epilepsy and deafness. This has provided the impetus to the establishment of large-scale mutagenesis programmes to generate new mutations. Tests of sensory and motor function have previously been most frequently used as these are simple to perform and the phenotypes are relatively obvious. Subtle phenotypes, of relevance to pyschiatric disorders such as anxiety and schizophrenia, can be detected using more complex tests. Screens such as prepulse inhibition and startle have been adapted for mice and these can be run with relatively high throughput using fully automated equipment. Other behaviours such as sleep and circadian rhythms, learning and memory and nociception can also be assessed. New technological advances in non-invasive imaging and neurochemical analyses have meant that these techniques can be readily applied to mouse phenotyping. The use of these screens together with mutagenesis is already beginning to increase the numbers of mouse models of potential relevance to CNS diseases.
