Abstract
One hundred and forty-one seven-year-old Swedish children took part in an extensive neuropsychiatric study involving total population samples of children who had shown perceptual, motor and attentional deficits in pre-school, and blindly examined comparison children. The present paper reports on generalized hyperkinesis, i.e. hyperactivity in the child in all of three different assessment settings. About a third of children diagnosed according to strict criteria as suffering from 'Minimal Brain Dysfunction' showed generalized hyperkinesis. In children without perceptual-motor deficits, hyperkinesis was very much rarer. A total population frequency for generalized hyperkinesis in the range of 1-3% is reported as probable. Heredity for delayed maturation, non-optimal pre-, peri- and neonatal factors and adverse psychosocial factors were found to interact in the shaping of the disorder.

Abstract
The total population of children born in 1971 and living in Gothenburg, Sweden, by the end of 1977 was screened in order to estimate prevalence figures for various neurodevelopmental disorders. Ninety-four percent of all children assessed attended public preschools. Questionnaires aimed at detecting perceptual, conceptual, motor, and attentional deficits were completed by preschool teachers for 72% of children in these schools. Samples of children with and without problems on the questionnaire were given neuropsychiatric examinations. National registers were searched to identify mentally retarded children not in public preschools. The total population frequency figure for unequivocal mental retardation was almost 1% with an additional 1% of the total population deemed to be of borderline intelligence.

Abstract
In an extensive neuropsychiatric study of seven-year-old children, operational criteria for diagnosing minimal brain dysfunction (MBD) syndrome were used. Detailed behavioural assessment and meticulous neurological examination provided the basis for the MBD diagnosis. The time-consuming specialist examination by the child neurologist was considered too sophisticated for use in everyday clinical practice. Therefore, the results obtained at a short neurodevelopmental screening assessment performed by a child psychiatrist were analysed with the aim of finding a limited set of neurological examination items with high discriminating capacity detecting for MBD syndromes. A set of six such items (diadochokinesis, hopping on one leg, standing on one leg, cutting out a paper circle, associated movements when walking on lateral sides of feet and the labyrinth test of the WISC) produced a minimal rate of misclassified cases. It is argued that this discriminant set may be useful in everyday child psychiatric and pediatric assessment of children who raise suspicion of suffering from MBD.

Abstract
A total population study of 4797 six-year-old children attending the public preschools in the city of Göteborg (Gothenburg) has been carried out. A questionnaire with 34 questions about MBD-related problems was distributed to all pre-school teachers. Three thousand four hundred and forty-eight questionnaires were completed. Factor analysis of the questionnaire and empirical results from a pilot study provided the basis for selecting for further study children with pre-school signs and symptoms suggestive of MBD. Neurological, psychiatric and psychological assessment of 82 children with, and 59 children without, pre-school symptoms of MBD revealed that in the index groups 41% of the children, and in the control group 3% of the children, had MBD. Extrapolation procedures gave a total population frequency of 1.2% with severe MBD and a further 5.9% with mild-moderate MBD. A very large questionnaire refusal rate (28%) is discussed. The relevance of the calculated frequency figures, especially as regards the mild-moderate MBD category, cannot be properly evaluated until long-term follow-up has been completed.

Abstract
Human leukocyte interferon was given as adjuvant treatment for osteosarcoma in 26 patients. Blood from these patients was studied at regular intervals for antibodies to various micro-organisms. A continuous record of clinically manifest infections during the course of interferon therapy was made in 23 of the 26 patients. Distant metastases arose in 14 patients - the metastasis group. The report presents comparisons between these patients and the non-metastasis group. Seroconversion in tests with any of the studied micro-organisms was not common. Most of the seroconversions were not associated with clinical symptoms. Seroconversion during interferon therapy was confined to patients in the metastasis group. In some cases there was a chronologic link with early evidence of metastasis. The results of the serologic investigations are discussed and are correlated to the course of interferon therapy and of the neoplastic disease.

Abstract
From 30 consecutive cases of premature rupture of the membranes (PROM) and matched controls, specimens from urine, cervix, amniotic fluid, and placenta as well as neonatal nose and throat swabs were investigated bacteriologically and virologically. In addition virus serological investigation was done. Among the PROM cases the anaerobic cervical isolates outnumbered the aerobic ones, and the total number of aerobic as well as anaerobic isolates was less in the control group. The anaerobes B. fragilis and Strept. intermedius were isolated from the cervix, amniotic fluid, or placenta in 23% and 30% of the PROM patients, respectively. None of the controls harboured B. fragilis, while Strept. intermedius was isolated from 6.7% of the controls. Group B streptococci were recovered from the mother's cervix in 20% of the PROM patients and in 6.7% among the controls. Four cases of neonatal septicaemia were encountered, and another two cases were clinically suspected, but not microbiologically verified, contributing to a high perinatal mortality rate (17,6%). Of the PROM patients, 27% developed puerperal infection, while none of the control mothers had such complications. The significance of the anaerobic bacteria as well as group B streptococci for the maternal and neonatal outcome in cases of PROM is discussed, and a possible aetiological role of ascending infection in this complication of pregnancy is postulated.

Abstract
This report concerns a boy with congenital rubella virus infection. The diagnosis was confirmed by virus isolation, demonstration of rubella-specific serum IgM and by persistence of serum antibody at the age of 9 months. In 2 sera from the mother sampled 2 weeks apart 20 months before the birth of the boy, low titers of rubella antibody were demonstrated by hemagglutination-inhibition, hemolysis-in-gel and complement fixation tests, but not by neutralization. Significant rises in titer were demonstrable by all serologic reactions--including neutralization--at the time of birth of the infected child. The mother was not aware of any rubella-like illness or exposure to such disease during pregnancy. The case is discussed against findings of neutralizing activity in sera from natural immunes and rubella vaccinees.

Abstract
Viral and bacterial infections in 20 children under 3 years of age were studied in a day centre for 12 weeks. Febrile illnesses were found on one occasion in each of 11 children but no serious infection occurred. Pneumococci types 6, 9, or 19 were isolated from all children but more often from those with rhinitis or cough. The individual child had an average of 2 viral infections. Adenovirus types 1, 2, 5, coxsackievirus type B5, herpes simplex virus or respiratory syncytial virus was isolated from 12% of the oropharynx swabs and 40% of the fecal specimens. When a virus was first isolated from the oropharynx, the children were asymptomatic or had only rhinitis in 73% of the cases which might indicate that the dismissing of symptomatic children is of limited value in controlling the spread of infections in a day care centre. Cytomegalovirus was recovered from 22% of the urine specimens. Carrier frequency of cytomegalovirus was 23% in 40 other children attending one of 13 different day care centers. Because asymptomatic cytomegalovirus infections apparently occur frequently among small children in Sweden, it seems reasonable not to take pronounced measures of isolating the children in the relatively few recognized cases of cytomegalovirus infections.

Abstract
The incidence of acute infections in eight patients with osteosarcoma who are receiving interferon regularly is currently being compared with the incidence among their family members. Observations thus far indicate that the patients treated with interferon are less frequently and less severely ill than their untreated family contacts. The study is continuing, and the patients will also be observed after discontinuation of interferon treatment. Sera are regularly frozen for future viral serologic tests. The preliminary clinical data indicate that therapy with exogenous interferon may afford protection against common acute infections.

Abstract
The polymorphic transferrin picture in the sera from 894 Swedish cattle was investigated with an agarose gel electrophoresis technique. The serum transferrin bands in the electrophoresis pattern were first identified by labelling with 59Fe. Six existing phenotypes based on the alleles TfA, TfD and TfE could be detected. The frequencies of transferrin types and transferrin alleles are presented, and it is concluded that there are great differences in the frequencies between the Swedish Red and White and the Swedish Friesian.

Abstract
The agarose gel electrophoresis described by Johansson (1972) was modified so that a buffer of pH 7.9 was used in the gel, whereas the buffer in the electrode vessels had a pH of 8.6. The cattle blood serum protein picture is described in detail. The β1-globulin zone shows a very distinct picture of the genetically polymorphic bovine transferrins. The region between the α- and β-globulins shows a number of faint and often very distinct bands. A faint background staining over the whole electrophoretogram may partly be caused by a rather strong lipoprotein in the α1-region, lipids thus having migrated all over the electrophoretogram. The modified method described is well suited as a “screen electrophoresis” for cattle serum and is also useful e.g. in studying bovine transferrin polymorphism.

Abstract
In healthy cows unaffected by imminent or recent calving the protein in serum can directly bind the overwhelming proportion of the bound calcium. In recent calvers this capacity is considerably less. When adding ammonium sulphate to blood serum to 62 % of total saturation a protein fraction precipitates which is mainly albumin. This fraction has a far greater calcium binding capacity than the soluble fraction, which contains most of the serum globulin, and the lowering of this capacity after calving is entirely referable to the former fraction. No difference has been found in these respects between normal cows after calving and cows with parturient paresis. An analysis of 10 amino acids in the two protein fractions described above showed that the amino acid composition of both exhibits differences between recent calvers and cows outside the calving period, and likewise that each of the two fractions differs in composition between healthy cows after calving and cows with parturient paresis.
