RESUMO
OBJECTIVES: This study aims to discuss and analyse the gambling habits and perceptions towards gambling cultures and problems among the large 'baby boomer' generation in Finland from an intersectional approach. These people born between 1945 and 1955 in their retirement or approaching retirement may face new risks regarding gambling. The results of this study support the designing of harm prevention among this ageing generation. STUDY DESIGN: Twenty-five people were interviewed in six focus groups. Participants' gambling experience varied from non-gambling to having experienced some problems. Three of the focus groups had participants with second degree education the highest, and three of the groups had participants with second degree education the lowest. Four interviews were conducted in the capital area and two in rural environments. METHODS: The group interview data were analysed with thematic content analysis. After initial coding in accordance with the research questions, subthemes and final themes were formed. Results are discussed through the final themes. RESULTS: The main results concern the gambling habits on the participants' life course: from shared, cultural experiences in their childhood to mostly minor gambling on the edge of retirement; the mutual understanding of the enormous growth in gambling supply during their lifetime, but emphasizing the importance of gambling monopoly for the society; and framing gambling problems as an individual tendency. CONCLUSIONS: The prevention of gambling harm within this generation needs to take into account the historical changes they have lived: from few, harmless gambling products framed as an instrument to support 'good causes' to the current world of commercial gambling. The deterministic understanding of gambling problems as an individual flaw may prevent recognizing problem gambling and seeking help to tackle the problems. Risks for gambling harm relate more to the gambling structures and cultures this ageing generation lives in, and the deterministic, individual understanding of gambling harm they share, than to marginalized positions they may have through gender or education.

An example of a useful and rapid procedure for the evaluation of interferences caused by complicated sample matrices in inductively coupled plasma atomic emission spectrometry (ICP-AES) is described. Using simple acid-base standards, all the elements investigated were determined separately in complicated matrices with satisfactory results. Multiple linear regression was used to calculate the linear correction coefficients for each matrix element analyzed. Good analytical results improved still further when this correction method was used.
RESUMO
PURPOSE: This study presents data on cumulative risk of seizures, cause, comorbidity, and remission of epilepsy among mentally retarded (MR) children followed until the age of 22 years. METHODS: A total of 151 MR children were identified at the age of 8 or 9 years by screening four birth cohorts of 12,882 children born from 1969 to 1972 in the Finnish province of Kuopio. Information about epilepsy was gathered longitudinally when children were 9 to 10, 17, and 22 years old. The guidelines for epidemiological studies on epilepsy proposed by the International League Against Epilepsy were followed. RESULTS: By the age of 10 years, 29 of the 151 MR children (19%) had epilepsy. The cumulative risk for epilepsy at 22 years was 21%. The probability of developing epilepsy was increased fivefold in severely MR children compared with mildly MR children, i.e., in 27 of the 77 severely MR children (35%) versus 5 of the 74 mildly MR children (7%). Postnatal causes of mental retardation or association with cerebral palsy increased the risk for epilepsy, especially in the mildly MR children. When these risk factors were not present, the mildly MR children exhibited only a 3% risk for epilepsy, whereas the respective risk was about 10-fold in severe mental retardation. The cumulative probability of epilepsy being in remission for 5 years by the age of 22 was 32%. CONCLUSIONS: The cumulative risk of epilepsy varies according to the severity and the cause of the retardation as well as the presence of additional disabilities. The cumulative probability of epilepsy remission tended to increase with age.

Direct ICP-AES measurements of the digested geological standard reference material samples yielded the wrong information about their composition. The differences between certified and measured concentrations of the samples were due to the complicated sample matrix. The measured concentrations can be successfully corrected by using a multiple linear regression technique. The correction is based on the multiple regression line calculated from the analytical results at synthetic mixtures of matrix elements, where concentrations varied on five levels. There were no significant (P = 0.05) differences between certified and measured concentrations in standard reference materials after the correction. The same method was used in the analysis of nutrition supplements.

The causes of mental retardation (MR) were studied as part of a multidisciplinary epidemiological case-control study in 151 mentally retarded patients identified by screening four age cohorts (12,882 children) at 8-9 years of age in the province of Kuopio, Finland. The causes of MR in 77 severely retarded (SD < or = -3 SD) and 74 mildly retarded (-2 > SD > -3) children were divided into pre-, peri-, postnatal and unknown groups according to the probable time of onset. The causes were pre-, peri-, postnatal and unknown in 60%, 9%, 8% and 23%, and 22%, 1%, 3% and 74%, in the two populations, respectively. Genetic causes were found in 28% of all 151 cases; the three most common subgroups were trisomy 21, fragile X syndrome and aspartylglycosaminuria (13%, 4% and 2% respectively). The study design used provided reliable information on the causes of MR and also demonstrated those forms of genetic metabolic diseases typical of Finnish inheritance.

The long-term clinical, neurophysiologic, and psychological effects of add-on vigabatrin treatment were evaluated in a group of 36 mentally handicapped patients with drug-refractory epilepsy. After an initial 3-month follow-up period, 15 (42%) of 36 patients had at least a 50% decrease in seizure frequency compared with baseline. After a 2-year follow-up period, nine (25%) of 36 patients retained the initially observed antiepileptic effects of vigabatrin, and after 5 years, eight (22%) of 36 patients did so. Five (33%) of the 15 patients who initially exhibited a favorable antiepileptic response to vigabatrin lost that response during a 5-year follow-up. Partial-onset seizures represented the seizure type best controlled by vigabatrin. Side effects were mostly mild, and plasma levels of other antiepileptic medication remained unchanged. No impairment of psychological performance was observed during vigabatrin treatment compared with baseline. Also, no clear change was observed in the background or epileptiform activity in the electroencephalogram during the study. Our findings suggest that vigabatrin as an add-on therapeutic effectively controls seizures in a subpopulation of patients with severe epilepsy. In addition, the antiepileptic response, if achieved, is long lasting in about half of the patients.

A high prevalence of the lysosomal storage disease aspartylglycosaminuria was found in a study of four birth cohorts of 12882 children in eastern Finland. Using school achievement tests and registers of mentally retarded individuals, 178 mentally retarded children were identified. Randomized urine samples from 151 of the 178 retarded children and from 101 healthy children were analyzed quantitatively for aspartylglucosamine by high-performance liquid chromatography. The results identified three affected individuals in the retarded group indicating an exceptionally high prevalence of aspartylglycosaminuria (1:3643) in the study population, consistent with a carrier frequency of 1:30. The 95% confidence limits for the prevalence are 1:4 352-1:16389. This is the highest prevalence described for any glycoproteinosis in any population and comparable to the incidence figures of the most common lysosomal storage diseases, Gaucher disease type I and Tay-Sachs disease among Ashkenazi Jews. In the study group, aspartylglycosaminuria was, after trisomy 21 (n = 19) and the fragile X syndrome (n = 6), the most common genetic cause for mental retardation.

The frequencies of folate-sensitive autosomal rare fragile sites (ARFS) were compared in populations of mentally retarded, mentally subnormal, and mentally normal children and of patients referred for diagnostic chromosome study. The frequencies did not differ significantly. Altogether, an autosomal rare fragile site was found in 16 of 1,445 individuals (1 in 90). Of six different folate-sensitive ARFS detected, the most common one was FRA9A, with a frequency of 1 in 241 individuals. In addition, FRA17A, classified as a distamycin A-inducible fragile site, was found with a frequency of 1 in 206. It was regarded as a spontaneously expressive fragile site. In 19 families in which transmission of an autosomal rare fragile site was studied, the mother was the carrier in 16 families and the father, in one family. The mean percentage (+/- SD) of cells expressing ARFS in 55 individuals was 19% (+/- 11.4). The age did not affect the rate of expression. When the rate of expression was calculated separately in a group of mentally retarded (mean = 23.4%) and in a group of mentally normal individuals (mean = 16.0%), the difference was statistically significant.

We studied the levels of excitatory and inhibitory amino acids in the cerebrospinal fluid (CSF) of 28 epileptic patients (24 with partial type seizures, 4 with primary generalized seizures) and 12 controls. The levels of aspartate were 63% (p less than 0.01), glutamine 129% (p less than 0.001), and homocarnosine 127% (p less than 0.005) that of controls. The concentrations of glutamate, asparagine, total GABA, free GABA, taurine, and glycine did not differ between epileptic patients and controls. Patients with partial epilepsy had a pattern of amino acids in CSF similar to that in patients with primary generalized seizures. In the present study we did not observe increased excitation or decreased inhibition in the seizure-active brains of epileptics, as far as the CSF levels of amino acids reflect their levels in the brain.

1. The anticonvulsant potency of vigabatrin (gamma-vinyl GABA, GVG) was studied in an open trial in a group of 21 mentally handicapped patients with drug-resistant epilepsy. 2. With this treatment one third of these patients had more than 50% reduction in seizure frequency. The anticonvulsant effect appeared during the first month of therapy and was maintained during a 7-month study. The side effects were mild: mainly tiredness, aggressiveness, and ataxia. Other anticonvulsant drugs remained at baseline levels during GVG therapy. GVG was not found to modulate EEG recordings. 3. According to our results, GVG is effective for treating intractable epilepsy in mentally handicapped patients.

Levels of total gamma-aminobutyric acid (TGABA), free GABA (FGABA), and homocarnosine (HC) were studied in CSF taken from 12 controls and 28 patients with drug-refractory epilepsy before and during 7 months of gamma-vinyl-GABA (GVG) administration. At baseline TGABA and FGABA in CSF of epileptic patients did not differ from that of the controls. In epileptic patients HC was 127% of that in controls. During GVG treatment TGABA was 283%, FGABA 197%, and HC 310% of the levels at baseline in the same patients. The patients who had over 50% reduction in seizure frequency during GVG (responders, 46% of the study population) at baseline had higher TGABA and HC in CSF than patients with less than 50% reduction in seizures (non-responders). During GVG the responders and nonresponders had similar levels of different GABAergic markers. The present study shows that in man GVG treatment effectively suppresses seizures in nearly half of the epileptic patients who had previously been drug-refractory. The elevated levels of GABAergic markers in CSF are not, however, necessarily related to good seizure control during GVG.

Vigabatrin (gamma-vinyl GABA) is a new anticonvulsive drug that irreversibly inhibits the activity of GABA transaminase. The effect of vigabatrin on neurotransmission-related amino acids in CSF of 28 epileptic patients was studied and the relationship between the amino acid pattern and clinical response during 7 months of administration of vigabatrin. Of this study population, 46% had more than 50% decrease in seizure frequency (responders). In 54% the seizures decreased less than 50% (nonresponders). In the whole study group, the levels of total GABA during vigabatrin treatment were 283%, free GABA 197%, homocarnosine 310% and glycine 128% that of the levels at baseline in the same patients. Glutamate, glutamine, aspartate, asparagine, and taurine concentrations did not change. The amino acid pattern in CSF during administration of vigabatrin did not differ significantly in responders and nonresponders. The study suggests that both GABAergic and glycinergic neurotransmission are affected by vigabatrin. The changes in CSF levels of neurotransmitter amino acids are, however, not necessarily related to the clinical response.

The present paper forms part of a larger prospective study and reports on the psychological performance of preterm children (n = 68) and fullterm control children (n = 36) at preschool age. Intelligence quotients (IQs) of intrauterine growth retarded (IUGR) preterm children were lower than those of appropriate-for-gestational-age (AGA) preterm children or fullterm controls at preschool age. Specific deficiencies (visuomotor, language) were found in 30% of the IUGR group and in 9% of the AGA group. When measuring general intellectual capacity, specific areas of intellectual function should be included by means of appropriate psychological tests, because a child may have a normal IQ but still show specific deficiencies.

We studied the antiepileptic potency of vigabatrin (gamma-vinyl GABA, GVG) as an open trial in a group of 36 mentally handicapped patients with drug-resistant epilepsy (30 had seizures of partial onset and 6 had primary generalized [PG] tonic-clonic convulsions). With this treatment, 13 (43%) of the patients with seizures of partial onset and 2 (33%) with PG had more than 50% reduction in seizure frequency. The antiepileptic effect appeared during the first month of therapy and continued throughout the 7-month study. The side effects were mild: tiredness, aggressiveness, and ataxia. Other antiepileptic drugs remained at baseline levels during GVG therapy. GVG did not alter EEG recordings. Our results suggest that GVG is effective for treatment of intractable epilepsy, especially the partial type, in mentally retarded patients. Longer follow-up is needed, however, to determine that the clinical effect is maintained and that no severe side effects appear.

Seventy-five epilepsy patients with at least two complex partial seizures/month were treated with gamma-vinyl GABA (GVG) 3 g/day for 3 months. Forty-one patients (54%) showed a reduction of greater than or equal to 50% in seizures. The median monthly seizure frequency decreased from 11.5 to 4 seizures/month. Twenty percent of patients had an improvement in general performance without a significant reduction in seizures. The responders entered the second phase of the study, in which 28 patients were randomly allocated to 3 g/day and 25 patients to 1.5 g/day GVG under double-blind conditions. The dosage of 3 g/day appeared to be clearly more effective than 1.5 g/day. However, even with 1.5 g/day GVG the seizure frequency was significantly reduced as compared to baseline. Drowsiness was the most commonly observed side effect, and it diminished with continued treatment. In three cases side effects led to the withdrawal of GVG therapy.

The value of correction-for-age in assessing psychomotor development during the first year of life was studied in prematurely born children. As part of a prospective follow-up study two pre-term age cohorts, born between 1976 and 1977, were evaluated prospectively to the age of 4.5 years. Data on first year psychomotor development were able to be collected concerning 66 prematurely born children and 36 full-term controls, whose neurodevelopmental and psychological status were found to be normal at the age of 4 years. On using uncorrected ages (chronological ages), achievement of developmental stages was significantly later among the premature children than among the fullterm children. If the corrected age was used, the developmental profile of the premature children became similar to that of the full-term controls. Over-correction in relation to the achievement of early developmental stages was found among very premature children (those born at or before 33 weeks of gestation). Over-correction diminished during the first year of life. On the basis of the present study, both corrected and uncorrected ages should be used when assessing first-year development, especially in very premature children.

As part of a prospective follow-up study of two premature cohorts (gestational age less than or equal to 36 weeks) born between 1976 and 1977, designed to evaluate the effects of IUGR on morbidity, mortality and neurological development in prematurely born children, 71 prematurely born children (48 AGA, 23 IUGR) without major neurological handicaps were subjected to detailed assessment of their neurological and psychological status at the age of 4 years. Thirty-six healthy full-term children formed a control group. The socioeconomic status of the families of the premature groups was similar to that of the families of the control group. The assessment consisted of a neurodevelopmental screening test and four psychological tests. Validation of the NDS test in relation to proven cognitive problems (sensitivity 96%, specificity 64%, relative risk 16.74) and determination of normal ranges were based on findings in the control group. There were significantly more children with moderate to high risk scores (greater than or equal to 10) among the IUGR group than among the AGA group. The neurodevelopmental profile of the preterm IUGR group was characterized by complex deviations of motor, visual and perceptual functions from normal. Preterm AGA children had only slightly higher risk scores in relation to fine motor, upper motor and perceptive functions than control children. Of the various perinatal factors studied, IUGR (especially in relation to boys who needed respirator therapy) was the most likely to be associated with abnormal NDS scores before school age.

The prevalence of the fragile X syndrome among 12,882 children (6594 boys and 6288 girls) born during the years 1969-1972 in Kuopio province in eastern central Finland has been studied retrospectively. Mentally retarded children were selected from normal schools by using school achievement tests and from registers of mentally retarded individuals. In the present study fragile X syndrome was found in 6/111 mentally retarded children (5.4%), in 4/61 boys and in 2/50 girls, respectively. It was not detected in the control group of 85 healthy children. The corrected prevalence of fragile X syndrome among boys in four successive birth cohorts was estimated to be 1 in 1210 or 0.8/1000, and that among girls, 1 in 2418 or 0.4/1000. The overall prevalence was calculated to be 1 in 1612 or 0.6/1000 children.
