RESUMEN

BACKGROUND: There is evidence for e-Health interventions for full-blown depression. Little is known regarding commonly untreated subthreshold depression in primary care. This randomized controlled multi-centre trial assessed reach and two-year-effects of a proactive e-Health intervention (ActiLife) for patients with subthreshold depression. METHODS: Primary care and hospital patients were screened for subthreshold depression. Over 6 months, ActiLife participants received three individualized feedback letters and weekly messages promoting self-help strategies against depression, e.g., dealing with unhelpful thoughts or behavioural activation. The primary outcome depressive symptom severity (Patient Health Questionnaire;PHQ-8) and secondary outcomes were assessed 6, 12 and 24 months. RESULTS: Of those invited, n = 618(49.2 %) agreed to participate. Of them, 456 completed the baseline interview and were randomized to ActiLife (n = 227) or assessment only (n = 226). Generalised estimation equation analyses adjusting for site, setting and baseline depression revealed that depressive symptom severity declined over time, with no significant group differences at 6 (mean difference = 0.47 points; d = 0.12) and 24 months (mean difference = -0.05 points; d = -0.01). Potential adverse effects were observed at 12 months, with higher depressive symptom severity for ActiLife than control participants (mean difference = 1.33 points; d = 0.35). No significant differences in rates of reliable deterioration or reliable improvement of depressive symptoms were observed. ActiLife increased applied self-help strategies at 6 (mean difference = 0.32; d = 0.27) and 24 months (mean difference = 0.22; d = 0.19), but not at 12 months (mean difference = 0.18; d = 0.15). LIMITATIONS: Self-report measures and lack of information on patients' mental health treatment. DISCUSSION: ActiLife yielded satisfactory reach and increased the use of self-help strategies. Data were inconclusive in terms of depressive symptom changes.

RESUMEN

We describe a 6-year-old, symptom-free girl presenting with a best corrected visual acuity of 0.6 on both eyes. Clinically we found yellowish subretinal lesions in the macula and around the vessel arcade without signs of vasculitis or abnormal vessels in the angiography. Fundus autofluorescence was marked and SD-OCT showed subretinal hyperreflective masses. With the help of molecular genetics we could make the diagnosis of an autosomal recessive bestrophinopathy (ARB). The natural history over 22 months revealed a slight recovery of the visual acuity as well as a slight reduction of the subretinal deposits.

RESUMEN

We investigated the effect of BoNT/A injection on hip lateralisation in children with bilateral spastic cerebral palsy and bilateral adductor spasticity. Pelvic radiographs using Reimers' migration index (MI) were evaluated from 27 children (n=9 females, n=18 males; mean age 5.2 ± 1.96 years; range: 2-10 years; initial MI <50%) with bilateral spastic cerebral palsy over a time period of 2 years. All received injections of BoNT/A (Dysport) every 12 weeks with a dose of 30 Units per kilogram body weight into adductor and medial hamstring muscles on both sides. The MI was calculated before treatment and after 1 and 2 years. The mean MI increased from 25.5% (range: 0-48) to 26.7% (+1.2%, range: 0-79) on the right side and from 28.0% (range: 0-40) to 30.6% (+2.6%, range: 3-84) on the left side over 2 years, respectively. Hips of one patient dislocated bilaterally. The mean MI remained stable over 2 years. Although a specific BoNT/A effect cannot be proven because of the open design of this study, we provide strong evidence that the MI can be kept stable for a time period of 2 years under non-surgical management including therapy with BoNT/A even in CP patients with a high risk for hip dislocation.

RESUMEN

OBJECTIVES: Prior studies suggested a high prevalence of complementary and alternative medicine (CAM) in Germany. The objectives of this study were (1) to describe in more detail the utilization of CAM, (2) to compare characteristics between CAM users and non-users, and (3) to delineate information on source of prescription and insurance coverage of 14 specific CAM therapies. METHODS: We extracted information derived from a computer-aided personal interview on the use of CAM, medical history, behavioral, and sociodemographic characteristics, all of which were generated by the Study of Health in Pomerania (formerly part of East Germany), a cross-sectional population-based survey. We analyzed data from 4291 individuals aged 20-79 years. RESULTS: Use of any CAM within the previous year was reported by 6.0% of the population. The modality used most widely among CAM users was active and passive exercise therapy (including various massage therapies). CAM users, when compared to non-users, were more likely to be female, experienced more years of education, were more physically active, less often overweight, reported a lower self-rated physical health status, and were more likely to visit an outpatient facility during the last year. There were higher proportions of several chronic diseases in CAM users than non-users. The results of this survey suggest that CAM therapies were most often utilized to alleviate pain. Most CAM therapies were prescribed by a physician. Reimbursement schemes were complex and differed according to therapy. CONCLUSIONS: The low estimate of CAM use might be explained by specific characteristics of the study region, including changes after the German reunification. CAM users and non-users differ with respect to several behavioral, sociodemographic and medical characteristics.

RESUMEN

OBJECTIVE: The aim of this study was to assess neuromodulative effects of CIMT in congenital hemiparesis. PATIENTS AND METHODS: Ten patients (age range: 10-30 years) with congenital hemiparesis due to unilateral cortico-subcortical infarctions in the middle cerebral artery territory, and with preserved cortico-spinal projections from the affected hemisphere to the paretic hand, were included. After a twelve-day period of constraint-induced movement therapy (CIMT), all showed a significant improvement of paretic hand function. Immediately before and after therapy, functional MRI during active and passive hand movements was performed to monitor cortical activation. RESULTS: Four patients showed consistent increases in cortical activation during movements of the paretic hand in the primary sensorimotor cortex of the affected hemisphere. Of the remaining six patients, three showed similar changes, but these results were potentially contaminated by an improved task performance after therapy. No significant alteration in activation was observed in two patients, and one showed movement artifacts. CONCLUSIONS: Even a short period of CIMT can induce changes of cortical activation in congenital hemiparesis. In our sample, increases in fMRI activation were consistently observed in the primary sensorimotor cortex of the affected hemisphere. Thus, the potential for neuromodulation is preserved in the affected hemisphere after early brain lesions.

RESUMEN

Previous studies have yielded conflicting results as to the putative role of the functional polymorphism of the promoter region of the serotonin transporter gene (SLC6A4) in the etiology of anxiety-related traits and depressive disorders. Recently, a significant gene-environment interaction was found between life stressors, the short allele of the SLC6A4 polymorphism and depression. The aim of the present study was to investigate if such a gene-environment interaction could be replicated within a different population with a different risk structure. A total of 1005 subjects from a general population sample (Study of Health in Pomerania) were genotyped. Mental and physical distress were assessed on 38 items of the modified complaint scale (BL-38). The interaction between the SLC6A4 genotype, social stressors and chronic diseases with regard to the BL-38 score was evaluated by ANOVA. There was no independent association of genotype with mental and physical distress. However, significant interactions between genotype, unemployment and chronic diseases (F = 6.6; df = 3, 671; P < 0.001) were found in females but not in males. The genotype explained 2% of the total variance of the BL-38 score and 9.1% of the explained variance. The results partly confirm previous findings of a significant gene-environment interaction of the short allele, indicating a higher mental vulnerability to social stressors and chronic diseases. The relevance of this finding is sustained by the fact that the sample characteristics and the risk structure were highly different from previous studies.

RESUMEN

OBJECTIVE: The purpose of this longitudinal study was to investigate the relationship between temperament (novelty seeking, harm avoidance and reward dependence), alcohol expectancies, membership in a deviant/substance-using peergroup and drinking behaviour of adolescents drawn from a general population. METHODS: 147 adolescents about 15 years of age were interviewed and completed several self-rating questionnaires. We gathered additional information by interviewing their parents. One year after the initial assessment the adolescents only were interviewed and given questionnaires again. RESULTS: Adolescents with alcohol problems at the time of the second interview reported less harm avoidance, less reward dependence, and were more likely to be a member of a deviant/substance-using peergroup a year before, compared to offspring without alcohol problems. Furthermore, they held more positive alcohol expectancies than adolescents without alcohol problems. Taking into account the quantity of alcohol consumed per occasion, all results were confirmed, but temperament did not predict the extend of alcohol consumed after one year. CONCLUSIONS: Alcohol expectancies and peer group deviance/substance-use are strongly associated to alcohol problems and the amount of alcohol consumed. Therefore, they should be the focus of prevention and intervention in this age group.

RESUMEN

BACKGROUND: Several studies from different epidemiological backgrounds have shown that unipolar depression is more prevalent in females than in males. This study examines gender differences in depression in a sample of 4075 probands recruited representatively from the general population in the northern German epidemiological catchment area of Lübeck. METHODS: Probands were interviewed with M-CIDI by lay interviewers. RESULTS: Being married only seems to increase the female depression risk when having children, while higher education reduced female excess; both male and female risk for depression raised sharply in separated, divorced and widowed probands. Not being employed was associated with an increased risk in male depression whereas in females risk was nearly unchanged. The gender ratio increased with the minimum number of depressive symptoms. Female excess was not reduced by a higher degree of subjective impairment or melancholic features. Females also predominated in longer episode durations. Female excess in the total group emerged beginning from adolescence with a tendency for a male excess in the prepubescent ages. No birth cohort effect was observed. LIMITATIONS: The cross-sectional design of this study precluded causal analysis of reported associations and some retrospective assessments are error-prone because of recall bias. CONCLUSIONS: We support previous findings of variations in gender differences in depression, however observed social parameter influences underline the need for a more detailed analysis of subgroups and underlying psychological mechanisms.

RESUMEN

AIMS AND METHODS: Alcohol withdrawal treatment efficacy of tiapride/carbamazepine (A) vs clomethiazole (B) vs diazepam (C) in non-intoxicated patients and vs tiapride/carbamazepine in intoxicated patients (D; breath alcohol concentration > or = 1 g/l) was tested (n = 127) in a controlled randomized open-label study. RESULTS: Efficacy and safety were not different between groups (total group: delirium, 3.9%; seizure, 0.8%), except for a lack of efficacy in 18% of intoxicated tiapride/carbamazepine patients. A change of medication in this group was necessary only when primarily intoxicated patients had reached the non-intoxicated range. CONCLUSIONS: Treatment with tiapride/carbamazepine in alcohol-intoxicated patients proved to be safe.

RESUMEN

We tested the use of some subscales of the psychiatric symptom checklist SCL-90-R in predicting relapse within a 1-year follow-up period after a combined detoxification- and abstinence-focused day patient psychotherapy program in 20 men and 13 women with alcohol dependence. Scores of the SCL-90-R subscales interpersonal sensitivity (p = 0.008), anxiety (p = 0.022), phobic anxiety (p = 0.019) and Global Severity Index (GSI; p = 0.040) on admission were higher in the subgroup with relapse within the first year after therapy. A decrease in depression (p = 0.004), anxiety (p = 0.006) and GSI (p = 0.006) scores during therapy was associated with a longer abstinence duration (shorter vs. longer than 24 weeks). Therefore we propose to further investigate the capacity of the SCL-90-R to identify subgroups at higher risk for relapse after detoxification and abstinence therapy in patients with alcohol dependence.

RESUMEN

Six hundred ten patients with seasonal affective disorder (SAD) were diagnosed and treated at the university hospitals for psychiatry in Bonn, Germany (1989-1992) and Vienna, Austria (1993-2001). The aim of this study was to compare our sample with other SAD populations in the literature and to investigate differences between the two study locations. We found female:male sex ratios of 5.0:1.0 in unipolar depressives and 1.5:1.0 in patients with bipolar affective disorder. Of our patients, 21.7% suffered from bipolar II disorder, and 1.3% were diagnosed as having bipolar I. Our patients obtained a mean global seasonality score (GSS) of 15.4. Women had a higher GSS than men (t = 2.127, P = 0.035), and Viennese patients had higher scores than patients in Bonn (t = 3.104, P = 0.002). Totals of 66.3% of all patients suffered from atypical depression and 17.8% from melancholic depression. Patients with atypical depression were more frequent in Vienna, whereas patients with melancholic depression predominated in Bonn (chi 2 = 54.952, df = 2, P < 0.001). The demographic and clinical characteristics of the patients described in this article confirm the findings of other epidemiological investigations obtained in non-German-speaking samples.

RESUMEN

In earlier studies, children of alcoholics (COAs) reported more alcohol and drug problems and higher levels of maladaptive behaviour and psychiatric distress than non-COAs. However, increased exposure to drugs and alcohol among COAs does not fully explain this phenomenon. In our family-based study design, we were able to investigate specific risk factors for alcohol problems in adolescence. In a first step, we compared a variety of psychosocial risk factors in 90 adolescents (12-18 years of age) from families with at least one alcohol-abusing parent with those of 90 adolescents of parents without alcohol disorders. In a second step, we investigated the meaning of all included risk factors for alcohol problems of the adolescents. Our results give some support to the existence of a lower extent of emotional warmth and support by parents of children in the COA sample. Moreover, males of the COA group reported more parental rejection and higher values on measures of attention problems and anxiety/depression than controls, whereas there were no such differences between females of the COA group and their control counterparts. Additionally, logistic regression analysis revealed that only the membership in a substance-using peer group and higher age are important risk factors for alcohol problems during adolescence. Considering our results, it is of great importance (a) to identify families at risk at the earliest possible stage and (b) to develop intervention and prevention programs further for parents and children to increase social competence and protect children at risk from later alcohol abuse.

RESUMEN

OBJECTIVE: The goals of this study are to provide estimates of clinical and demographic variables of patients with seasonal affective disorder (SAD) in Germany and Austria, to compare our results with those of previously published SAD studies, and to find out whether the clinical pattern of SAD remained stable over several years. METHOD: We investigated 610 SAD patients from the outpatient clinics in Bonn (n = 190) and Vienna (n = 420). Patients in Bonn were recruited in the fall-winter season of the years 1989-1992, those in Vienna in the years 1993-2001. RESULTS: We observed a change in the clinical pattern in our patients: patients from Bonn, who were diagnosed and treated about 5 years earlier, were more likely to suffer from melancholic depression, whereas Viennese patients rather suffered from atypical depression (chi(2) = 54.952, df = 2, p < 0.001). The symptoms of hypersomnia, daytime fatigue, increased eating and carbohydrate-craving were more frequent in the Viennese sample, anxiety and deterioration of patients' capacity to perform at work predominated in Bonn. In addition, patients from Vienna obtained a higher GSS (global seasonality score, measured by the SPAQ - Seasonal Pattern Assessment Questionnaire) than those from Bonn (15.7 +/- 3.3 and 14.6 +/- 4.1 respectively; t = 3.104, p = 0.002). Taken together, our results were in good accordance to other published SAD materials, but we were able to demonstrate that our patients reported "feeling worst" (measured by item 13H of the SPAQ) in November and December, whereas SAD patients in the USA clearly had their worst months in January and February. CONCLUSIONS: We suggest that an increase in awareness of fall-winter depression in the last decade by both doctors, who referred patients, as well as patients or the entire population must have caused patients to sign up for light therapy at the Viennese SAD clinic because of having heard about the atypical symptom profile. This increased awareness of SAD can also be measured by a statistically significant reduction in the diagnostic latency (from the age of onset to the diagnosis of SAD) when comparing the two study locations.

RESUMEN

The difference Delta(a)=a(30)-a(28) of the lattice parameter of 30Si and 28Si crystals is measured over a temperature range from 4.7 to 700 K. In disagreement with existing knowledge, the strongest isotopic effect is not detected at the lowest achieved temperature T=4.7 K. An anomalous behavior is observed: The relative difference |Delta(a)/a| attains its maximum value of 56.8(5) ppm at T=75(10) K. The anomalous behavior is attributed to the influence of phonon modes with negative Grüneisen parameters. At T=700 K the effect still amounts to 30% of the maximal value. The experimental data are consistent with an approach based on the density-functional perturbation theory.

RESUMEN

We tested the hypothesis that allelic variants of the human dopamine D2 receptor E8 genotype are associated with (i) dopamine D2 antagonist tiapride dose in treatment of alcohol withdrawal (n = 50) and (ii) with anxiety and depression in patients during alcoholism detoxification therapy (admission n = 87; discharge n = 50). DRD2 E8 A/A genotype was associated with increased dose of tiapride during a 9-day detoxification therapy and with increased anxiety and depression scores on admission and 2 weeks later. The findings suggest a pharmacogenetic influence of DRD2 E8 genotype on tiapride efficacy in alcohol withdrawal. In an earlier report, DRD2 E8 A/A genotype was associated with reduced responsiveness to the dopamine D2 agonist apomorphine; however, it is not clear whether both findings share the same biological basis. Earlier findings concerning association of DRD2 E8 A/A with increased anxiety and depression are replicated for the first time.

RESUMEN

In this study, 57 women were examined in terms of the influence of different psychosocial factors on their subsequent mental well-being and physical complaints one day before, one day after, and 3 months after undergoing an in-patient abortion. Furthermore a control group of 40 in-patients (women with pregnancy related problems) were included in the study. The results show that prior to the abortion, most women reported a multitude of psychological and physical problems. However, it was also shown that for the majority of the women interviewed, mental well-being and physical complaints improved significantly one day and 3 months after the abortion. While feelings such as relief predominated immediately postoperatively, after 3 months, participants reported feeling cheerful and interested in activities. Further, it was demonstrated that women whose general mood was more pronouncedly anxious-depressive one day prior to operation later (after 3 months) reported many complaints and worse well-being. It appears that these women were not able to experience the abortion as a problem solutions. Finally, the great importance of the quality of their relationship and cohesion was demonstrated in the decision to abort, while pregnancy counselling was found to have no effect.

RESUMEN

The results of this study provide evidence for the importance of psychosocial risks in childhood for aggressive behavior in adolescence. This study demonstrated that aggressive adolescents differed from a nonaggressive control group in an increased exposure to prior psychotraumatic events, such as sexual abuse (tendency), physical abuse, and broken homes. However, in predicting later aggressive behavior, long-term and chronically effective negative living conditions seem of greater importance. Parenting behavior which includes harsh punishment and emotional rejection as well as separation of the parents early in life are particularly important factors. Whereas aggressive girls do not differ from the nonaggressive control group in terms of self-reported mental health, the aggressive boys reported more attention deficits, depression, anxiety, delinquency, and social problems.

RESUMEN

The wavelength of the 57Fe Mössbauer radiation is measured with a relative uncertainty of 0.19 ppm by using almost exact Bragg backscattering from a reference silicon crystal. Its value is determined as lambda(M) = 0.860 254 74(16)x10(-10) m. The corresponding Mössbauer photon energy is E(M) = 14 412.497(3) eV. The wavelength of the 57Fe Mössbauer radiation is easily reproducible with an accuracy of at least 10(-11)lambda(M) and could be used as a length standard of atomic dimensions.
