[Impact of early life maltreatment of women on the mother-child relationship : Data from mother-child dyads from Heidelberg and Berlin]. / Einfluss früher Gewalterfahrungen von Frauen auf die Mutter-Kind-Beziehung : Daten von Heidelberger und Berliner Mutter-Kind-Dyaden.

Early life maltreatment can have severe and long-lasting consequences for the directly affected individual as well as for the next generation. Data from our research including mother-child dyads from Heidelberg and Berlin show that early life maltreatment is associated with behavioral and neural changes including personality traits and attachment style of the affected mothers that negatively affect their relationship with their child. The children of these mothers affected by early life maltreatment have an elevated risk to be maltreated and to develop mental disorders. They also show a heightened cortisol concentration and a reduced inhibition control. It seems to be of importance whether the mother has experienced early life maltreatment but is resilient, meaning that she has not developed a mental disorder (up to the time of examination) or whether in addition to the early life maltreatment she has developed a mental disorder later in life. Children of mothers with early life maltreatment and a lifetime mental disorder seem to be especially exposed to stress and show the greatest impairments and risks. Based on the existing data from our research practical and clinical implications are discussed and one possible intervention in the form of a training of mentalization competencies for parents is presented.

Maternal avoidance, anxiety cognitions and interactive behaviour predicts infant development at 12 months in the context of anxiety disorders in the postpartum period.

BACKGROUND: Few studies have examined the relation between anxiety disorders in the postpartum period and cognitive as well as language development in infancy. AIMS: This longitudinal study investigated whether anxiety disorder in the postpartum period is linked to infant development at twelve months. A closer look was also taken at a possible link between maternal interaction and infant development. STUDY DESIGN: Subjects were videotaped during a Face-to-Face-Still-Face interaction with their infant (M = 4.0 months). Specific maternal anxiety symptoms were measured by self-report questionnaires (Anxiety Cognition Questionnaire (ACQ), Body Sensations Questionnaire (BSQ), Mobility Inventory (MI)) to check for a connection with infant development. The Bayley Scales of Infant and Toddler Development-III (Bayley-III) were used to assess infant language and cognitive development at one year of age. SUBJECTS: n = 34 mothers with anxiety disorder (SCID-I; DSM-IV) and n = 47 healthy mothers with their infant. OUTCOME MEASURES: Infant performance on Bayley-III language and cognitive scales. RESULTS: Infants of mothers with anxiety disorder yielded significantly lower language scores than infants of controls. No significant group differences were found regarding infant cognitive development. Exploratory analyses revealed the vital role of "maternal avoidance accompanied" in infant language and cognitive development. Maternal neutral engagement, which lacks positive affect and vocalisations, turned out as the strongest negative predictor of cognitive development. Maternal anxiety cognitions and joint activity in mother-infant interaction were the strongest predictors of infant language performance. CONCLUSIONS: Results underline the importance to also consider the interaction behaviour of women with anxiety disorders to prevent adverse infant development.

Postpartum bonding: the impact of maternal depression and adult attachment style.

Maternal depression poses a risk for the developing mother-infant relationship. Similarly, maternal insecure attachment styles may limit the ability to adequately connect with the newborn during the postpartum period. The aim of this study was to investigate the effect of maternal depression and insecure attachment (insecure and dual/disorganized) on maternal bonding in a sample of n = 34 women with depression according to DSM-IV and n = 59 healthy women. Maternal depression was assessed 3 to 4 months postpartum with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), bonding with the Postpartum Bonding Questionnaire, and maternal attachment style with the Attachment Style Interview. Women with current and lifetime depression as well as women with dual/disorganized attachment style reported lower bonding. Explorative analysis revealed that depression partially mediated the link between dual/disorganized attachment style and bonding with a medium-sized mediation effect. The combination of maternal depression and dual/disorganized attachment style may pose a special risk constellation for the developing mother-infant bond that should be addressed in prevention and early intervention programs.

Rectal atresia and anal stenosis: the difference in the operative technique for these two distinct congenital anorectal malformations.

Rectal atresia and anal stenosis are rare forms of anorectal malformations. The aim of the definitive surgical repair in such cases is to preserve the anal canal, the dentate line, and the sphincter complex. We present a case of rectal atresia and anal stenosis to demonstrate the differences in the operative repair. The techniques described leave the anterior wall of the very distal anal canal untouched in both rectal stenosis and anal atresia; however, the dissection of the rectum differs. The atretic rectum in rectal atresia is mobilized and sutured to the anal canal circumferentially. In anal stenosis, the posterior rectum is mobilized in the form of rectal advancement, and the posterior 180° is anastomosed directly to the skin (as in a standard PSARP) with preservation of the anal canal as the anterior 180° of the final anoplasty. These patients have an excellent prognosis for bowel control and fecal continence, and therefore, complete mobilization and resection of the anal canal must be avoided.

Perceived parenting stress in the course of postpartum depression: the buffering effect of maternal bonding.

Research investigating maternal bonding and parenting stress in the course of postpartum depression is lacking. Aim of the study was to investigate the development and potential mediation of both constructs in the course of postpartum depression. n = 31 mothers with postpartum depression according to DSM-IV and n = 32 healthy controls completed the German version of the Postpartum Bonding Questionnaire and the Parenting Stress Index at two measuring times: acute depression (T1) and remission (T2). At T1, the clinical group reported lower bonding and higher parenting stress. Bonding was found to partially mediate the link between maternal diagnosis and parenting stress. Furthermore, the clinical group reported lower bonding and higher parenting stress averaged over both measurement times. However, at T2, the clinical group still differed from the controls even though they improved in bonding and reported less parenting stress. A significant increase of bonding was also observed in the control group. Maternal bonding seems to buffer the negative impact of postpartum depression on parenting stress. The results emphasize the need for interventions focusing on maternal bonding and mother-infant interaction in order to prevent impairment of the mother-child relationship.

Postpartum bonding: the role of perinatal depression, anxiety and maternal-fetal bonding during pregnancy.

Adverse effects of perinatal depression on the mother-child interaction are well documented; however, the influence of maternal-fetal bonding during pregnancy on postpartum bonding has not been clearly identified. The subject of this study was to investigate prospectively the influence of maternal-fetal bonding and perinatal symptoms of anxiety and depression on postpartum mother-infant bonding. Data from 80 women were analyzed for associations of symptoms of depression and anxiety as well as maternal bonding during pregnancy to maternal bonding in the postpartum period using the Edinburgh Postnatal Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI), the Pregnancy Related Anxiety Questionnaire (PRAQ-R), the Maternal-Fetal Attachment Scale (MFAS) and the Postpartum Bonding Questionnaire (PBQ-16). Maternal education, MFAS, PRAQ-R, EPDS and STAI-T significantly correlated with the PBQ-16. In the final regression model, MFAS and EPDS postpartum remained significant predictors of postpartum bonding and explained 20.8 % of the variance. The results support the hypothesized negative relationship between maternal-fetal bonding and postpartum maternal bonding impairment as well as the role of postpartum depressive symptoms. Early identification of bonding impairment during pregnancy and postpartum depression in mothers plays an important role for the prevention of potential bonding impairment in the early postpartum period.

Maternal bonding in mothers with postpartum anxiety disorder: the crucial role of subclinical depressive symptoms and maternal avoidance behaviour.

Hardly any research has examined the link between postpartum anxiety disorder and maternal bonding. This study examined if postpartum anxiety disorder and maternal bonding are related in the postpartum period. Thereby, subclinical depressive symptoms and specific aspects of an anxious symptomatology were also taken into consideration. The German sample of N = 78 mother-infant dyads is composed of n = 30 mothers with postpartum anxiety disorders but without major or minor depression according to the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) and n = 48 healthy mothers. Subjects were interviewed with the Structured Clinical Interview for DSM-IV Disorders at an average infant age of M = 4.1 months. Moreover, mothers filled out the Postpartum Bonding Questionnaire-16. The Anxiety Cognitions Questionnaire, the Body Sensations Questionnaire and the Mobility Inventory were chosen to assess different aspects of anxious symptomatology. To control for concurrent subclinical depressive symptoms, we used the German Edinburgh-Postnatal-Depression Scale. Mothers with postpartum anxiety disorder reported significantly lower bonding than healthy mothers. However, in a linear regression analysis, concurrent subclinical depressive symptoms and avoidance of anxiety-related situations in company explained 27 % of the overall variance in maternal bonding. The perceived lower bonding of mothers with anxiety disorder could be due to aspects of a concurrent subclinical depressive symptomatology. This notion emphasizes the need to target even mild depressive symptoms in the treatment of postpartum anxiety disorders. The outcomes also underline that the severity of anxious symptomatology, reflected by avoidance behaviour in company, puts the mother-infant bond at risk.

Prevalence of paternal perinatal depressiveness and its link to partnership satisfaction and birth concerns.

Depressive disorders have shown an increasing prevalence over the past decades. Growing evidence suggests that pregnancy and childbirth trigger depressive symptoms not only in women but likewise in men. This study estimates the prevalence of paternal perinatal depressiveness in a German community sample and explores its link to partnership satisfaction as well as birth-related concerns and concerns about the future. Data was gathered in a longitudinal study over the second and third trimester of their partner's pregnancy up to 6 weeks postpartum. In a two-stage screening procedure, 102 expectant fathers were assessed for symptoms of depression, anxiety, and partnership satisfaction using the Edinburgh Postnatal depression Scale (EPDS), the State/Trait Anxiety Inventory, a self-constructed questionnaire for birth concerns and the Questionnaire of Partnership. The prevalence of elevated depressive symptoms among expectant fathers was 9.8 % prenatally and 7.8 % postnatally. Prenatal relationship quality, prenatal EPDS scores, and birth concerns were significantly associated with and explained 47 % of the variance in paternal postnatal depressive symptoms. The prevalence of paternal depressive symptoms is a significant concern. Our findings point out the need for implementing awareness and screening for depressiveness in fathers in clinical routine in Germany as well as the necessity of developing a screening instrument for paternal birth-related anxiety.

Discontinuities in slow finger movements in patients with Parkinson's disease.

Slow finger movements in healthy humans are characterized by discontinuous rhythmic changes in a low frequency band about 8 Hz. These pulsatile changes in velocity are thought to present the central output of an oscillatory cerebello-thalamo-cortical network in the same frequency. Hypothesizing that patients with Parkinson's disease (PD) in the dopaminergic OFF- and ON-condition show changes in the characteristics of discontinuities compared to healthy humans, we used a 3D-ultrasound device to measure slow finger movements of 16 patients with PD and 12 age-matched controls. We provide evidence that slow finger movements of patients with PD are characterized by discontinuities in acceleration, which are significantly slower in the OFF- but not in the ON-condition compared to healthy controls. Correlation analysis between clinical motor improvement after dopaminergic medication and changes of peak frequencies and peak power of discontinuities was not significant. We conclude that the oscillatory brain network of slow finger movements is affected in PD, presenting in a lower frequency in the OFF-condition. We suggest that one factor of the modulation of this network is a dopaminergic stimulation.

The influence of general anxiety and childbirth-specific anxiety on birth outcome.

In the present study, we examined a German sample to determine whether anxiety symptoms during pregnancy had an impact on the duration and method of childbirth. Data of N = 88 women recruited at the Heidelberg University Hospital were used in the analyses. Prepartum anxiety symptoms were assessed with the State-Trait Anxiety Inventory (STAI, general anxiety) and the Pregnancy Related Anxiety Questionnaire (PRAQ-R, pregnancy-specific anxiety). Obstetric outcome was taken from birth records and operationalized by two parameters: the total duration of birth (dilation and fetal expulsion) and the incidence of pregnancy or birth-related interventions (ventouse, planned, and unplanned Cesarean section). The data show that childbirth-specific anxiety assessed by the PRAQ-R is an important predictor of total birth duration. In contrast, general anxiety measured by the STAI had no effect. The incidence of birth intervention was explained by parity. Anxiety, however, had no predictive value. In addition to medical factors, childbirth-specific anxiety during pregnancy plays an important role in the process of childbirth. The findings of the present study point to the need of implementing psychological interventions to reduce childbirth-specific anxiety and thereby positively influencing birth outcome.

Modulation of local field potential power of the subthalamic nucleus during isometric force generation in patients with Parkinson's disease.

Investigations of local field potentials of the subthalamic nucleus of patients with Parkinson's disease have provided evidence for pathologically exaggerated oscillatory beta-band activity (13-30 Hz) which is amenable to physiological modulation by, e.g., voluntary movement. Previous functional magnetic resonance imaging studies in healthy controls have provided evidence for an increase of subthalamic nucleus blood-oxygenation-level-dependant signal in incremental force generation tasks. However, the modulation of neuronal activity by force generation and its relationship to peripheral feedback remain to be elucidated. We hypothesised that beta-band activity in the subthalamic nucleus is modulated by incremental force generation. Subthalamic nucleus local field potentials were recorded intraoperatively in 13 patients with Parkinson's disease (37 recording sites) during rest and five incremental isometric force generation conditions of the arm with applied loads of 0-400 g (in 100-g increments). Repeated measures analysis of variance (ANOVA) revealed a modulation of local field potential (LFP) power in the upper beta-band (in 24-30 Hz; F(3.042)=4.693, p=0.036) and the gamma-band (in 70-76 Hz; F(4)=4.116, p=0.036). Granger-causality was computed with the squared partial directed coherence and showed no significant modulation during incremental isometric force generation. Our findings indicate that the upper beta- and gamma-band power of subthalamic nucleus local field potentials are modulated by the physiological task of force generation in patients with Parkinson's disease. This modulation seems to be not an effect of a modulation of peripheral feedback.

Does increased gamma activity in patients suffering from Parkinson's disease counteract the movement inhibiting beta activity?

Akinesia and rigidity are cardinal symptoms of Parkinson's disease (PD). Previous studies analysing event-related desynchronization during movement onset associated both symptoms with pathologically increased oscillations in the beta frequency range. By focusing on the movement onset only, these studies cannot, however, shed light onto the question how oscillatory activity is changed during continuous movements. To investigate this issue, we compared the power of the local field potentials (LFP) within and above the subthalamic nucleus (STN) during rest, an isometric hold condition of the forearm, and a fist flexion and extension task in 13 patients with idiopathic PD during implantation of deep brain stimulation (DBS) electrodes. During fist flexion and extension (relative to rest), significantly increased activity in the low beta (12-18 Hz) and gamma (30-48 Hz) frequency ranges was observed within the STN, while during hold (compared to rest) no significant difference was found. For the regions above the STN the power during fist movements (compared to rest) was significantly higher, i.e. in the range of 18-30 Hz, with no significant changes in the gamma frequency range. Beta activity is claimed to inhibit movement and thereby could render fist movements more exhausting. Therefore, the observed increase in beta activity in the STN during fist movements might result in bradykinesia as experienced by many patients. We hypothesise that in order to enable repetitive fist movement despite increased beta activity, "prokinetic" gamma activity may be increased as a compensatory mechanism.

Subclinical depressive symptoms during pregnancy and birth outcome--a pilot study in a healthy German sample.

There is a high prevalence of depression in Germany and all over the world. Maternal depressive symptoms during pregnancy have been shown in some studies to be associated with an increased risk of preterm birth and low birth weight. The influence of maternal depressive symptoms during pregnancy on preterm delivery and fetal birth weight was investigated in a prospective single-centre study. A sample of 273 healthy pregnant women was assessed for symptoms of antepartum depression. Symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) and the Patient Health Questionnaire (PHQ). Symptoms of anxiety were assessed using the State/Trait Anxiety Inventory. Patients who scored above the cutoff were contacted by phone for a Structured Clinical Diagnostic interview. Neonatal measurements were obtained from the birth registry of the Department of Obstetrics. Baseline data were assessed with a self-styled data sheet. Prevalence of elevated depressive symptoms was 13.2% when measured with the EPDS and 8.4% with the PHQ. According to DSM-IV criteria, only four (EPDS) respective two (PHQ-D) of these patients could be diagnosed with a depressive disorder and ten (EPDS) respective seven (PHQ) with an anxiety disorder. There was no significant influence on preterm birth or birth weight. Maternal depressive symptoms are self-reported. Elevated subclinical symptoms of depression and anxiety during pregnancy are common. However, this study showed no evidence that these symptoms are associated with adverse pregnancy outcome.

Subtype-specific statistical causalities in parkinsonian tremor.

Tremor is one of the cardinal symptoms of Parkinson's disease. Up to now, however, its pathophysiology remains poorly understood. Previously, oscillatory coupling at tremor frequency between the subthalamic nucleus und affected muscles was shown. In these studies, however, causality of coupling could not be demonstrated. Thus, we analyzed the statistical causality between intraoperatively recorded local field potentials in the subthalamic area and affected arm muscles during tremor episodes, using squared partial directed coherence, a recently developed causality measure. The analysis identified differential statistical causality patterns for Parkinson's disease patients of the akinetic-rigid subtype during tremor episodes (n=6) versus patients of the tremor-dominant subtype (n=8): for the akinetic-rigid Parkinson's disease patients significantly more cases of the subthalamic region were found to be statistically causal for electromyographic-tremor activity, a result in accordance with the standard basal ganglia model. In contrast, for the tremor-dominant patients, significantly more instances of electromyographic tremor activity turned out to be causal for activity of the subthalamic region. Furthermore, the clinical effective stimulation site coincided with the location of most input causalities from the periphery in seven out of eight tremor-dominant patients. The data suggest that, although tremor activity in tremor-dominant and akinetic-rigid Parkinson's disease patients was clinically similar, statistical causality between tremor electromyogram (EMG) and the subthalamic nucleus was fundamentally different. Therefore, we hypothesize different pathophysiological mechanisms to underlie the generation of tremor in the two subtypes of Parkinson's disease.

MRI graduation of osseous reaction and drill hole consolidation after arthroscopic Bankart repair with PLLA anchors and the clinical relevance.

PURPOSE: Conventionally, radiography studies revealed prolonged glenoidal drill hole visibilities with an unclear influence to the clinical outcome after arthroscopic Bankart repair using Poly-Laevo-Lactic-Acid (PLLA) anchors. The primary aim of the present study was the separated assessment of drill hole consolidation (DHC) and the concomitant osseous reaction (OR) of the glenoidal bio-degradation process in new specific magnetic resonance grading systems. In accordance with the specific DHC and the OR graduation, the clinical relevance was the secondary focus. METHODS: Twenty-eight patients with arthroscopic Bankart repair using knotless PLLA anchors were prospectively followed and analyzed using a clinical scoring system (3, 6, 15 and 32 months). The T2-weighted OR and T1-weighted DHC were assessed using specific magnetic resonance imaging grading protocols (15 and 32 months). RESULTS: Longitudinal assessments revealed successive clinical status improvements over time (32 months: Rowe 95.7 ± 3.8; Walch-Duplay 93.8 ± 6.6; Constant 93.9 ± 4.5; ASES 93.8 ± 6.9; DASH 28.6 ± 7.2; NAS(pain) 1.1 ± 1.3; NAS(function) 1.3 ± 1.4). The initial OR level regressed over the 15-32 month period while the DHC showed significant drill hole reductions (P < 0.05). The inferior glenoid revealed a significantly increased bio-degradation capacity (P < 0.05) with drill hole enlargements in 14.3%. Neither the OR nor the drill hole enlargements influenced the clinical status. In no case were clinical or radiologic signs for a foreign body reaction. CONCLUSION: Knotless bio-anchors provide secure glenoidal fixation for Bankart repair without any specific clinical or MR evidence of an inflammatory response. The clinical status remained unaffected by the bio-degradation process. LEVEL OF EVIDENCE: IV.

MRI assessment of the structural labrum integrity after Bankart repair using knotless bio-anchors.

PURPOSE: Adequate labral restorations after Bankart repair have been demonstrated in cadaver models for knot-tying and knotless anchors and in vivo by magnetic resonance imaging for knot tying. The influence of glenoidal bio-degradation on clinical outcome, and conclusions regarding drill hole enlargement and foreign body reactions remain controversial. METHODS: The labrum was analyzed in magnetic resonance images for 37 consecutive patients with Bankart repair using knotless PLLA anchors and for 31 volunteers as radiologic controls. The labrum was assessed regarding slope, height index (quotient between labral height to the glenoid height), and labrum morphology in axial and coronal T2 images. Glenoidal bio-degradation was graded in terms of the drill hole configuration in T1 images and the corresponding osseous reaction in T2 images. Constant-Murley, Walch-Duplay, and Rowe scoring were carried out preoperatively and at follow-up. RESULTS: At 15 months after arthroscopy, the anterior slope (24.8°), height index (3.0), inferior slope (25.4°), and height index (2.5) were not significantly different from control values. Morphologic analysis revealed significant changes in the Bankart group (P < 0.05) that were influenced by the number of preoperative dislocations. Bio-degradation proceeded slowly with no evidence of drill hole enlargement. Osseous reactions were significantly greater in inferior compared to superior implants. The clinical scores were excellent and were not influenced by bio-degradation. CONCLUSIONS: Knotless anchors facilitate labral restoration that is comparable to the knot-tying approach. Bio-degradation proceeds slowly without clinical or radiologic evidence of foreign body reactions. LEVEL OF EVIDENCE: III.

Delayed referral despite appropriate knowledge in cryptorchidism as a cause of delayed orchidopexies in Austria.

AIM: Guidelines recommend early orchidopexy in cryptorchidism to decrease the risk of infertility and tumor formation. We aimed to asses if a delayed initial presentation for cryptorchidism was due to unawareness of these guidelines or for any other reasons. METHODS: A short questionnaire exploring timing and referral habits when assessing children with cryptorchidism was sent by email to all registered pediatricians in Austria. Comparatively, a chart review of performed orchidopexies was performed at our institution. RESULTS: Of 369 registered pediatricians, 102 (27.6%) returned valid questionnaires. The average maximum age at which pediatricians in Austria suggested treatment of cryptorchidism was the 21.2 (8.4 months standard deviation (SD)) month of life. Assessment of testicular descent was reported to be regularly performed until the 8.8 (3-18 years SD) year of life. In contrast, from 1997-2008, 730 boys were treated surgically for cryptorchidism at our department. The mean age at operation was 3.4 years (3.1 years SD). CONCLUSION: The majority of pediatricians in Austria know the correct timing for treatment of cryptorchidism. Nevertheless, orchidopexies are still carried out to later than suggested by international guidelines. Further studies and analysis to evaluate the reasons for these suboptimal referring patterns coupled with further communication improvements between pediatricians and surgeons are needed.

Perceived parental rearing in subjects with obsessive-compulsive disorder and their siblings.

OBJECTIVE: Perceived parenting in patients suffering from obsessive-compulsive disorder (OCD) is examined. We attempted to overcome some methodological limitations of prior studies by taking age of onset, parental OCD and comorbid depression into consideration. In addition, we included data from unaffected siblings to corroborate information on parental rearing. METHOD: One hundred and twenty-two cases with OCD and 41 of their siblings as well as 59 healthy controls and 45 of their siblings completed the German short-version of the EMBU (FEE). RESULTS: Obsessive-compulsive disorder cases reported less parental warmth and more parental rejection and control. Further analyses indicated that parenting is also associated with OCD in cases with late onset and cases without parents affected by OCD. OCD cases with comorbid depression described their parents particularly negatively. Data from siblings indicated good validity of perceived parenting in OCD. CONCLUSION: This study provides further evidence for dysfunctional child rearing being relevant to the development of OCD and depression.
