RESUMEN

Oncological treatment of head and neck carcinoma is associated with high morbidity. Measuring of health-related quality of life (HRQoL) is crucial in this patient group but there is no consensus on which measure would be preferable to be used. In this study, HRQoL was measured with the generic 15D, which has not been used before for assessing this patient population. It is a prospective cohort study among 64 patients with laryngeal, pharyngeal or nasal cavity carcinoma treated with definitive (chemo) radiotherapy between November 2007-July 2012. HRQoL was assessed with the 15D before and at 3, 6 and 12 months after the treatment onset. HRQoL results of the patients were compared with those of the age-standardized general population. Overall HRQoL declined significantly during the first 3 months after the treatment onset but then gradually improved towards the end of the follow-up. At baseline or at 12 months, no significant differences were detected in overall HRQoL between the patients and the general population. Dimensions reflecting mental well-being showed gradual improvement, exceeding the baseline scores at the end of the follow-up. Nevertheless, on these dimensions, the patient group presented with consistently lower scores compared with the general population. The mean HRQoL was lower among patients with pharyngeal carcinoma compared with the laryngeal carcinoma patients. The 15D instrument is feasible for evaluation of HRQoL in oncologically treated head and neck cancer patients. It seems to detect differences among different patient subgroups. Multidisciplinary supportive management of this patient population is recommended to ensure improved mental well-being.

RESUMEN

BACKGROUND: Deviant birth measure is a risk factor for later somatic illness but also for later psychiatric disorders of the offspring. Only a few studies have examined the association of birth measures to later psychiatric disorders among adolescents. Studies on sex differences in these associations are scarce as well. METHODS: The cases consisted of 508 adolescents (208 boys and 300 girls) aged 12-17 years, who were admitted to inpatient psychiatric hospitalization between 2001 and 2006. In addition, 478 healthy controls were derived from the Northern Finnish Birth Cohort 1986, born in approximately the same period and same area as the cases. Data of birth measures were collected from the National Birth Register for cases and from antenatal clinics for controls. Both cases and controls were interviewed using the Schedule for Affective Disorder and Schizophrenia for School-Age Children-Present and Lifetime (K-SADS-PL) to assess psychiatric disorders. RESULTS: The adolescent patients were statistically significantly shorter and had higher ponderal index at birth compared to healthy controls. In addition, the age of the mothers at adolescent's birth was significantly younger in the patients than the controls. After controlling for various covariates, a 2.4-fold increased likelihood for internalizing disorders was seen among male adolescents with high ponderal index. CONCLUSIONS: The association of birth measures to psychiatric disorders was confirmed in our study, particularly among male adolescents suffering from internalizing disorders. Further studies in larger adolescent samples are needed to confirm our findings and clear up the association of high ponderal index to specific psychiatric disorders.

RESUMEN

BACKGROUND: Students with mathematical learning disabilities (MLD) struggle with number processing skills (e.g., enumeration and number comparison) and arithmetic fluency. Traditionally, MLD is identified based on arithmetic fluency. However, number processing skills are suggested to differentiate low achievement (LA) from MLD. AIMS: This study investigated the accuracy of number processing skills in identifying students with MLD and LA, based on arithmetic fluency, and whether the classification ability of number processing skills varied as a function of grade level. METHODS AND PROCEDURES: The participants were 18,405 students (girls = 9080) from Grades 3-9 (ages 9-15). Students' basic numerical skills were assessed with an online dyscalculia screener (Functional Numeracy Assessment -Dyscalculia Battery, FUNA-DB), which included number processing and arithmetic fluency as two factors. OUTCOMES AND RESULTS: Confirmatory factor analyses supported a two-factor structure of FUNA-DB. The two-factor structure was invariant across language groups, gender, and grade levels. Receiver operating characteristics curve analyses indicated that number processing skills are a fair classifier of MLD and LA status across grade levels. The classification accuracy of number processing skills was better when predicting MLD (cut-off < 5 %) compared to LA (cut-off < 25 %). CONCLUSIONS AND IMPLICATIONS: Results highlight the need to measure both number processing and arithmetic fluency when identifying students with MLD.

RESUMEN

BACKGROUND: The purpose of the present study was to examine the association of overweight with suicide ideation, self-mutilative behavior (SMB) and suicide attempts among underage psychiatric inpatient adolescents. SAMPLING AND METHODS: Data were collected from 439 adolescents (age = 12-17 years) admitted to psychiatric hospitalization between April 2001 and March 2006. Information on adolescents' suicidal behavior and psychiatric DSM-IV diagnoses was obtained by using the Schedule for Affective Disorder and Schizophrenia for School-Age Children. An adolescent was defined as overweight if his/her BMI exceeded the 85th percentile BMI in the age- and sex-matched Finnish population. RESULTS: Compared to adolescents without overweight, a 2.5-fold likelihood for SMB was found among overweight girls, but not among boys. CONCLUSIONS: Low self-esteem, depression or dysfunctional emotion regulation may be possible mediating factors between overweight and SMB.

RESUMEN

OBJECTIVE: To evaluate, in a clinical sample of children with a diagnosis of specific language impairment (SLI), the health-related quality of life (HRQoL). SUBJECTS AND METHODS: Fifty-five children, aged 8-11 years, filled out a generic HRQoL questionnaire, 17D, and another questionnaire about school and rehabilitation. The HRQoL comparison group was a sample of 244 typically developing schoolchildren. RESULTS: Response rate was 86%. Of the respondents, 80% were male. The total 17D score of the subjects did not differ from that of controls. The 17D profiles of the groups differed on several dimensions, but significant differences emerged only on the dimensions concerning speech, where the study group was worse off, and sleep, where the controls reported more problems. Respondents with low verbal IQ reported more distress. The vast majority of respondents were in special education or received extra educational support and one-third were still having speech therapy. CONCLUSION: In this clinical sample, despite the persisting need for extra support, the overall well-being of children with SLI was at age level. Still, some differences existed, and HRQoL measurement may prove a good tool for professionals to find those children with SLI at risk for diminished well-being and for later problems.

RESUMEN

BACKGROUND: Dispatching centres were fused into one of the 112 entity, which caused concerns regarding whether the medical calls could be processed effectively also in the new centre. We evaluated the effects of the reform on key performance criteria in medical calls. METHODS: This observational study in the Helsinki Dispatching Centre consisted of two periods: Period I 2 years before the reform and Period II 2 years after. The main outcome measures were answering and call processing times, accuracy of risk assessment and appropriate use of ambulances. RESULTS: In Period I (n=574,276), 92.2% of all incoming phone calls were answered within 10 s and in Period II (n=758,022) 82.8% (P<0.0001). Time to dispatch a first responding fire unit increased from 98 to 113 s (P<0.0001) and an advanced life support unit in category A calls increased from 73 to 84 s (P<0.0001). In Period I 47.7%, 34.8% and 17.5% of phone calls were completed in <3, 3-5 and >5 min and in Period II 29.8%, 36.1% and 34.1% (P<0.0001). The number of three studied non-transportation call types and unnecessary lights-and-siren responses increased significantly (P<0.0001 and 0.0001, respectively). Neither the accuracy of risk assessment in the three studied call types nor the rate of telephone-guided cardiopulmonary resuscitation changed. CONCLUSIONS: The reform increased the total number of ambulance dispatches, prolonged answering and call processing times and had a negative effect on the appropriate use of ambulances. The accuracy of risk assessment was not affected. Evidence-based data should be the basis for the future as dispatching centre processes are shown to be vulnerable during organisational reforms.

RESUMEN

AIMS: To assess the impact of superficial venous surgery (SVS) on health-related quality of life (HRQoL) and to explore the cost-utility of venous surgery. MATERIAL AND METHODS: 143 patients (110 female and 33 male) enrolled for SVS between 2003 and 2005 in Helsinki University Central Hospital filled in the 15D survey before and six months after operation. Direct hospital costs were obtained from a patient administration database and were examined from the perspective of secondary care provider. RESULTS: After SVS, the HRQoL score improved in 71% of the patients, and the mean score increased from 0.919 (on a 0-1 scale) preoperatively to 0.933 postoperatively at 6 months (p < 0.001). Patients with a clinically important result from SVS (> or = 0.03 increase in the HRQoL score) had significantly worse HRQoL at baseline. At 6 months postoperatively, the mean (SD) hospital costs were 1637 euros (693) and the mean quality-adjusted life year (QALY) gain 0.504 (1.674), respectively. Thus, the mean cost per QALY gained during a 6-month period was 3248 euros for SVS. CONCLUSIONS: Superficial venous surgery improves HRQoL, and is a cost-effective treatment of symptomatic superficial venous insufficiency.

RESUMEN

The effectiveness and cost-utility of nasal continuous positive airway pressure (nCPAP) treatment was evaluated in obstructive sleep apnoea syndrome (OSAS), using a 15D health-related quality of life (HRQoL) instrument in a routine clinical setting. In total, 78 OSAS patients (43 receiving nCPAP; 35 receiving lifestyle guidance) were included in the study. nCPAP treatment had a minor effect on the total HRQoL score; only the dimension of sleep improved in both groups. The mean +/- SD number of quality-adjusted life years (QALYs) gained was 0.016 +/- 2.34 in the nCPAP group and 0.386 +/- 1.16 in the lifestyle guidance group. The mean cost per QALY gained was euro73 375 for the nCPAP group and euro845 for the lifestyle guidance group. The effect of nCPAP treatment on the HRQoL in a population of unselected OSAS patients was surprisingly small and the cost per QALY gained was high.

RESUMEN

OBJECTIVE: The health-related quality of life (HRQoL) of adults with childhood diagnosis of specific language impairment (SLI) was evaluated. PATIENTS AND METHODS: Fifty-two patients with a childhood diagnosis of SLI were asked to fill out the 15D-HRQoL questionnaire. The patients were selected from a hospital setting from psychological examination reports showing a below-average verbal intelligence quotient (VIQ) and a normal performance intelligence quotient (PIQ). The 15D was completed adequately by 33 patients (response rate 63.5%). The results were compared with those of age- and gender-matched controls. RESULTS: The total 15D score of the study group was lower than that of population controls, but the difference was not statistically significant. The study group performed significantly worse on the dimensions of speech, usual activities, mental function and distress. Gender or PIQ in childhood was not correlated with the 15D scores or dimension scores in adulthood. Childhood VIQ was associated with the dimensions of mental function (p < 0.01) and usual activities (p < 0.05). CONCLUSION: Our results support earlier findings that SLI affects the entire life span. Identification of prognostic factors and a prolonged follow-up of SLI patients could improve the QoL of these patients.

RESUMEN

To study the possible influence of childhood language impairment on adult life and well-being, 35 persons with a mean age of 34 years filled out two questionnaires. Compared with the general population, subjects more often lived with parents, and were pensioned. Only a few reported having literacy problems, but over 40% had difficulty in finding words and remembering instructions. Childhood performance IQ was associated with education and word-finding difficulties, and verbal IQ with difficulties in remembering instructions. Health-related quality of life was related to literacy skills, finding words, and remembering instructions. In conclusion, adults with childhood language impairment differ markedly from the general population. Problems in expressing themselves and receiving information affect their well-being the most. Childhood performance seems to have some prognostic value for language-based problems in adulthood.

RESUMEN

OBJECTIVE: Although seasonal variation in impulsive aggression related to circannual rhythms of central serotonin neurotransmission is a topic of current interest, there is little firm knowledge on seasonality in the occurrence of homicide. Longitudinal studies on the seasonal rhythms of platelet imipramine binding and L-tryptophan levels have placed the circannual peaks around January and February and the nadirs around May and August. The aim of this study was to test the hypothesis that the number of homicides is the lowest during winter and the highest during spring and summer. A secondary hypothesis was that the seasonal variations in homicides and violent suicides are correlated. METHOD: The largest database on the monthly occurrence of homicide thus far (N = 4,553) was used in this study, in which the monthly occurrence of all murders and manslaughters in Finland during the years 1957-1995 was analyzed. RESULTS: During winter the homicide rate was 6% below the expected rate. Correspondingly, during summer there was a 6% elevation above the expected homicide rate, but no significant peak was observed in spring. There was a significant association between the monthly occurrence of homicides and violent suicides but not between homicides and nonviolent suicides. CONCLUSIONS: The results suggest that a seasonal variation in the occurrence of homicide exists. On the basis of current literature, it could be hypothesized that this seasonal variation and the correlation between the monthly occurrence of homicides and violent suicides are associated with the observed circannual rhythms of serotonin transmission.

RESUMEN

OBJECTIVE: The purpose of the study was to examine the quantitative risk of criminal behavior associated with specific mental disorders. METHOD: An unselected 1966 birth cohort (N = 12,058) in Northern Finland was prospectively studied until the end of 1992. The investigation started during the mothers' pregnancy, and the data on the subjects' family characteristics, mental and physical development, living habits, psychiatric morbidity, and criminal records were gathered at various times. RESULTS: The prevalence of offenses was the highest among males with alcohol-induced psychoses and male schizophrenic subjects with coexisting alcohol abuse, and more than half of the schizophrenic offenders also had problems with alcohol. Eleven (7%) of the 165 subjects who committed violent crimes were diagnosed as psychotic. Male schizophrenic subjects had a moderately high risk for violent offenses, but the risk for other types of crimes was not elevated significantly. Odds ratios for criminal behavior were adjusted according to the socioeconomic status of the childhood family and were the same as or slightly lower than the crude odds ratios for all disorders except schizophrenia and mood disorders with psychotic features. CONCLUSIONS: The results indicate that the risk of criminal behavior was significantly higher among subjects with psychotic disorders, even though the socioeconomic status of the childhood family was controlled. The higher risk for violent behavior was associated especially with alcohol-induced psychoses and with schizophrenia with coexisting substances abuse. The results suggest that schizophrenia without substance abuse may also be associated with a higher risk of offenses, but this finding is tentative and requires further investigation.

RESUMEN

OBJECTIVE: Serious defects in social skills acquired during childhood may be associated with aggressive behavior in later life. The authors studied whether being an only child was associated with criminality in adulthood and, secondly, if parental factors increased the putative risk. METHOD: The authors used an unselected, prospectively collected large birth cohort. Data on crimes were linked with being an only child as well as with perinatal risk and maternal and paternal psychological risk factors among male subjects. RESULTS: The risk for violent crimes later in life was elevated among the only children. If perinatal or parental risks were combined with being an only child, the odds ratios for violent offending increased four-fold to eight-fold. A corresponding risk increase between being an only child and nonviolent offending was not detected. CONCLUSIONS: These results support the hypothesis that growing up as an only child is associated with violent criminality among male subjects.

RESUMEN

OBJECTIVE: The goal of this study was to test the hypothesis that maternal smoking during pregnancy is associated with greater risk for criminal behavior of the offspring in adulthood. METHOD: An unselected, general population cohort composed of 11,017 subjects (5,636 men, 5,381 women) was followed up prospectively from the sixth month of pregnancy to age 28 years. Interviews with the mother during the pregnancy, health records, and an assessment of the offspring at age 1 year provided information on risk factors. The Ministry of Justice provided information on criminal offenses for all subjects. RESULTS: Because of the low rate of criminal offenses among women, the present analyses are restricted to men (N = 5,636). Compared to the sons of mothers who did not smoke, the sons of mothers who smoked during pregnancy had more than a twofold risk of having committed a violent crime or having repeatedly committed crimes, even when other biopsychosocial risk factors were controlled. While maternal smoking during pregnancy alone explained 4% of the variance associated with violent offenses among male offspring, it was not significantly associated with nonviolent offenses among male offspring. When maternal smoking during pregnancy was combined with a maternal age of less than 20 years, a single-parent family, an unwanted pregnancy, and a developmental lag in walking or talking, the odds ratios for violent offenses increased up to ninefold and for persistent offenses up to 14-fold. CONCLUSIONS: Maternal smoking during pregnancy is associated with violent offenses and persistent offenses, but not with nonviolent offenses, among male offspring in adulthood.

RESUMEN

RATIONALE: Several studies have shown that impulsive violent behavior is associated with reduced serotonin metabolism in the brain, but no data exist on possible alterations of the serotonin precursor (free L-tryptophan) levels among violent offenders. OBJECTIVES: To study free L-tryptophan and kynurenine plasma levels among antisocial violent offenders. METHODS: Free L-tryptophan and competing amino acid (CAA) plasma levels were measured among 19 male impulsive antisocial violent offenders and 19 age-matched healthy male controls. RESULTS: Mean free L-tryptophan/(CAA) plasma levels were 160% (95% CI 116%-204%) higher among offenders than controls (P=0.000). Seventeen of the 19 offenders (89.5%) had values of more than 2 SD above the mean value of controls. The levels of kynurenine, the major metabolite of tryptophan, were slightly increased in offenders. CONCLUSION: Free plasma L-tryptophan/CAA levels were markedly increased among antisocial violent offenders indicating a disturbed tryptophan metabolism.

RESUMEN

It has been suggested that schizophrenic patients fail to develop left-hemisphere dominance because of an early disturbance in neuronal development. This hypothesis has been supported by some post-mortem. CT and magnetic resonance imaging (MRI) studies, while other in-vivo studies have given contradicting results. We used 122-channel whole-head magnetoencephalography and MRI to locate the sources of auditory evoked responses in 19 schizophrenic patients and in 20 healthy controls. Auditory evoked responses were detected in all subjects. The left-right hemisphere asymmetry of cerebral sources for auditory evoked responses was markedly dispersed among patients when compared with controls. The source locations for left auditory cortex were clearly anterior with respect to the right hemisphere in 32% of the patients, while the corresponding prevalence of this abnormal asymmetry was 0% in controls (p = 0.008. Fisher's exact test). The reversed asymmetry appeared to be associated with a shorter anterior-posterior distance between the auditory cortex and the anterior tip of the temporal lobe in the left side when compared with the right side. The reversed asymmetry was associated with higher PANSS general psychopathological score, and especially with higher guilt feelings and motor retardation scores. The large 2.5-fold standard deviation in the inter-hemispheric anterior posterior difference in the location of the auditory cortex among patients (p 0.001 for the difference in the magnitude of variance between controls and patients) clearly reflects the dispersion of the left right asymmetry into both direction, and three of the patients with 'normal asymmetry' had a greater left-right asymmetry than any of the controls. Markedly greater reversal of hemispheric asymmetry among patients implies that regulation of the development of brain asymmetry is disturbed among schizophrenic patients. Abnormality in the cerebral asymmetry may be a crucial factor in the development of schizophrenic disorder in a substantial proportion of patients. The results suggest that the reversed asymmetry is associated with the higher severity of general psychopathological symptoms.

RESUMEN

A common functional polymorphism that results in a three- to four-fold difference in catechol-O-methyltransferase (COMT) enzyme activity has been related to psychiatric disorders such as ultra-ultra rapid cycling bipolar disorder, drug abuse and alcoholism (Lachman et al., 1996a; Karayiorgou et al., 1997; Vandenbergh et al., 1997; Papolos et al., 1998; Tiihonen et al., 1999). Several studies have also reported associations between the allele encoding the low enzyme activity COMT variant (L allele) and other-directed aggression (Strous et al., 1997; Lachman et al., 1998; Kotler et al., 1999) in schizophrenic and schizoaffective patients. The current study investigated whether the COMT L allele is also associated with suicide attempts in schizophrenic and schizoaffective patients. COMT genotypes were determined and history of suicide attempts was retrospectively investigated in a Finnish sample (n = 94) and a US sample (n = 54). Significant associations were observed between COMT genotype and suicide; specifically, history of violent suicide attempts. The COMT L allele was more frequent in subjects who had attempted suicide by violent means. These associations were significant in males but not females. These findings support a common neurobiological substrate for self- and other-directed aggression, and suggest that catecholaminergic alterations may contribute to these behaviors in schizophrenic and schizoaffective patients.

RESUMEN

It has been suggested that schizophrenia and alcoholism are associated with violent behavior. But so far there are no published studies from unselected cohorts quantifying the actual risk associated with schizophrenia both with and without comorbid alcoholism. In this study, an unselected birth cohort (n = 11,017) was prospectively followed to the age of 26, and data on psychiatric disorders and crimes were collected from national registers. The odds ratios for violent offenses and recidivism were calculated for each diagnostic group. Men who abused alcohol and were diagnosed with schizophrenia were 25.2 (95% confidence interval (CI) 6.1-97.5) times more likely to commit violent crimes than mentally healthy men. The risk for nonalcoholic patients with schizophrenia was 3.6 (95% CI 0.9-12.3) and for other psychoses, 7.7 (95% CI 2.2-23.9). None of the patients with schizophrenia who did not abuse alcohol were recidivists (> 2 offenses), but the risk for committing more crimes among alcoholic subjects with schizophrenia was 9.5-fold (95% CI 2.7-30.0). This study suggests that to prevent the crimes being committed by people with schizophrenia, it is important that clinicians watch for comorbid alcohol abuse.

RESUMEN

Both animal and human studies imply that aggressive behaviour is associated with increased dopaminergic transmission. Our hypothesis was that impulsive violent offenders have also higher heterogeneity of the striatal dopamine transporter (DAT) density than controls. We performed a fractal analysis in 21 impulsive violent offenders, 10 non-violent alcoholics and 21 controls to measure the heterogeneity and laterality of the striatal DAT density characterised by [123I]beta-CIT single-photon emission tomography (SPET). The [123I]beta-CIT distribution was significantly more heterogeneous in the right striatum of violent offenders than in healthy controls. In addition, in young violent offenders there was no normal left-to-right asymmetry observed in control subjects of the same age. The normalisation of the left-to-right asymmetry may reflect late neurobiological maturation.

RESUMEN

BACKGROUND: Some studies have indicated that there are wide variations on incidence and prevalence of bipolar disorder in specific populations. METHODS: The occurrence of bipolar affective disorder and the age at onset was studied in both genders among the hospitalized Finnish population. RESULTS: The annual rate of all hospitalized patients with bipolar disorder was 0.03%. Of these, 2% were under 20 years, 14% under 30 years, 61% under 50 years and 81% under 60 years of age. The 1-year incidence was highest in the age group 50-59 years in males and 40-49 years in females. CONCLUSIONS: The low prevalence and incidence of bipolar disorder in Finland may be due to late onset-age. LIMITATION: The study is based on hospital-treated bipolar disorder patients. CLINICAL RELEVANCE: We have presented previously unreported differences between the age of onset of bipolar disorder in Finland compared with other countries.
