We directly compared nonlinear kernels of normal human pattern electroretinograms (PERGs) and corresponding localized flash ERGs (FERGs). The FERG was triphasic and resembled an adaptive process because it decayed slowly without changing shape over several kernel orders and interpulse intervals. The PERG was biphasic in the slice nearest the diagonal ...

During the first half of this century, the seasonal pattern of births in European countries showed a major peak in the spring and a minor peak in the autumn. In contrast, the pattern in the US was of a minor peak in spring and a major peak in autumn. Over ...
Pulver A E - - 1990
Contrary to the position taken by Lewis (1989), several articles have demonstrated an association between season of birth and the risk of schizophrenia after controlling for the age-incidence effect. The method used by Pulver et al. (1983) was misinterpreted by Lewis. Clarification of this method is provided along with additional ...

The Guest Editor introduces this Theme Issue of the Schizophrenia Bulletin with an overview of the kinds of subject matters appropriate for a comprehensive understanding of the vital statistics and demography relating to schizophrenia and schizophrenic patients--births, deaths, marriages, divorces, fertility, age, sex, race, occupation, place of residence, season of ...
Dalén P - - 1988
Maternal age is a neglected variable, with obvious implications for aetiology, in psychiatric research. In samples of schizophrenic patients, the distributions by month of birth and maternal age at birth show remarkable anomalies. These phenomena may be connected, because the seasonal distribution of births varies with maternal age, probably as ...

The raised incidences of strong left-handedness and of mixed-handedness in homosexual men, as in dyslexics, are mutually consistent under the normal distribution function, as expected by the right shift theory of handedness. It is argued that atypical laterality in these groups is better described as a "reduction of right shift" ...
McNally S L SL Shongwe Hospital, - - 1987
The epidemiology of snakebite in 251 patients admitted to Shongwe Hospital is described for the period 1978-1982. The incidence of bites, their seasonal variation, environmental and population factors, age and sex variations, the bite-site, bite-admission time and bite incidents are analysed. First-aid is frequently administered inappropriately even when given by ...
Jørgensen A - - 1987
The Copenhagen longitudinal high-risk study of offspring of 129 schizophrenic mothers commenced in 1962. At that time, the mothers were diagnosed according to contemporary Danish criteria. We have re-examined all of the hospital records of these mothers: 108 (84%) fulfil present-day DSM-III criteria for schizophrenia and 95 (74%) were diagnosed ...
van Strien J W - - 1987
A large nonclinical sample of left-handed and right-handed subjects completed laterality and medical health questionnaires. The group of left-handed subjects showed a raised incidence of birth complications and learning disorders whereas no differences were found for birth order and maternal age. Left-handed and right-handed subjects showed similar incidences of autoimmune ...

Measurement of chemotaxis of neutrophil polymorphonuclear leukocytes (PMNs) is often performed by micropore-filter methods. However, most of these methods seem to involve considerable inter-individual, intra-individual, and day-to-day variations. The aim of this study was to compare two frequently used micropore-filter methods - the Lower Surface Count (LSC) and the Leading ...
Kendell R E - - 1987
Data from two sources--the Edinburgh Psychiatric Case Register and the psychiatric inpatient records of the Scottish Health Service--were used to compare large populations of first-admission schizophrenics born in winter (January to March) and in summer (June to October). Parallel comparisons were carried out for affective psychoses. Comparison of the months ...
