左室舒张末压、外周阻力与甲襞微循环的相关性

为探讨甲襞微循环在判断心脏前后负荷中的意义，以微循环图像仪定量检测６０例慢性充血性心衰病人的甲襞微循环，同时以二维超声心动图按改良Ｓｉｍｐｓｏｎ氏法测定左室舒张末压、外周阻力加以对照。结果表明：随着左室舒张末压的增高，甲襞微血管输出枝及袢顶直径、面积增大，流速显著减慢。而在高外周阻力状态中，则相应微血管输入枝及袢顶直径、面积缩小，管袢数显著减少。所有指标差异均具显著性。结果提示，甲襞微循环的检测是估计心脏前后负荷功能的可靠指标     

机械性窒息与胸部挤压伤所致脑微循环改变的比较

在实验的基础上对比研究单纯性机械窒息和胸部挤压伤所致的脑微循环改变、脑血流、颅内压、血及脑脊液乳酸的变化。结果显示单纯机械性窒息２ｍｉｎ后微循环明显变化，胸部挤压伤５ｍｉｎ后出现更明显改变。微循环障碍早期表现为微血管扩张、血流加速，后期血管通透性增加、流速减缓，直至血流淤滞、红细胞溢出。单纯性窒息颅内压升高较缓慢、幅度小，胸部挤压伤颅内压急骤升高、幅度大，二者有明显差别。因此，包含有颅内压升高和缺血缺氧二因素的胸部挤压伤对微循环有较大的损害。

Development of Dissociation: Examining the Relationship Between Parenting,Maternal Trauma and Child Dissociation

SUMMARY

While many studies have demonstrated relationships between trauma and dissociation, relatively little is known about other factors that may increase children's risk for developing dissociative symptoms. Drawing on betrayal trauma theory and Discrete Behavioral States frameworks, the current study examined the contributions of maternal factors (including mothers' dissociation, betrayal trauma experiences, and inconsistent parenting) to children's dissociation. Seventy-two mother-child dyads completed self-report questionnaires. Maternal dissociation was found to relate positively to maternal betrayal trauma history. Additionally, both mothers' and children's betrayal trauma history were found to significantly predict children's dissociation. Implications for the intergenerational transmission of betrayal trauma and dissociation are discussed.     

Peripheral vascular surgical procedures in Ilorin, Nigeria: indications and outcome

Background

Data on peripheral vascular surgical interventions from Nigeria is scanty. Reports form Western and Eastern Nigeria dates back about twodecades. This study therefore analyses the various etiological conditions necessitating intervention, and their outcome.

Methods

A retrospective analysis of patients requiring surgical intervention on peripheral vessels from a prospectively collected single surgeon database over a two-year period was conducted. Data were analysed using SPSS version 15.0 windows statistical package.

Results

Fourteen peripheral vascular surgical procedures were performed. The age range was 2–70years (24.4±16.3) with five cases (35.7%) in 20–29year group. Trauma accounted for 11 (73.3%) cases. Upper limb involvement occurred in 7 (63.6%) of the traumatic cases whereas all 2 true aneurysm occurred in the lower limb. Direct repair was possible in re-establishing anatomic continuity in about 64% of cases. Of the six morbidities, wound infection accounted for 50% followed by failure of re-vascularizaton (33.3%) and there was one mortality.

Conclusion

Trauma is the leading cause of peripheral vascular condition necessitating surgery from our study. Young adults predominate. Though direct repair are often feasible, there is a need for the availability of graft options. Wound infection constitutes the highest post-operative morbidity.     

Relationship Between Childhood Trauma,Mindfulness, and Dissociation in Subjects With and Without Hallucination Proneness

The purpose of this study was to examine the relationship between childhood traumas, mindfulness, and dissociation (more specifically, absorption and depersonalization) in healthy subjects with and without hallucination proneness. A sample of 318 subjects was given the Launay-Slade Hallucination Scale–Revised (R. P. Bentall & P. Slade, 1985). From this sample, 2 groups were formed: one with high and the other with low hallucination proneness. Furthermore, all participants were given the Tellegen Absorption Scale (A. Tellegen & G. Atkinson, 1974), the Cambridge Depersonalization Scale (M. Sierra & G. E. Berrios, 2000), the Southampton Mindfulness Questionnaire (P. D. J. Chadwick et al., 2008), and the Trauma Questionnaire (J. R. E. Davidson, D. Hughes, & D. G. Blazer, 1990). The results showed that in the group with high hallucination proneness, there were significantly more subjects with traumatic experiences than in the group with low predisposition, although no significant difference in the mean number of traumatic experiences undergone in childhood was found between the 2 groups, although there was a trend toward significance. A correlation analysis showed a significant negative association between mindfulness on the one hand and absorption and depersonalization on the other. A positive relationship was also found between childhood traumas and absorption and depersonalization. Finally, multiple mediation analysis showed that the absorption and depersonalization variables acted as mediators between childhood traumas and hallucination proneness. We discuss the importance of the relationship between the variables studied and hallucination proneness and suggest some approaches for their treatment.     

The Relationship Between Pathological Dissociation,Self-Injury and Childhood Trauma in Patients with Personality Disorders Using Taxometric Analyses

ABSTRACT

Objective: Dissociative phenomena exist on a spectrum ranging from psychological absorption to highly symptomatic disruptions of identity and memory. A statistical methodology called taxometric analysis has established a set of indicators that identify patients who have pathological dissociation, a qualitatively different form of dissociative phenomena. Using taxometric methodology, this study examines the relationship of pathological dissociation to personality diagnosis and self-directed injury, including suicide and history of childhood abuse, in a sample of outpatients with personality disorders.

Method: Patients were recruited from advertisements or referred from local clinicians. Participants completed a diagnostic interview and rating scales for dissociation, self-injury and childhood trauma. Pathological dissociation was identified using the Dissociative Experiences Scale-Taxon (DES-T; Waller, Putnam, & Carlson, 1996). Membership in the pathological dissociation taxon was established by calculating Bayesian posterior taxon membership probabilities; the method advocated by Waller, and compared to an approximation, used widely in the literature, based simply on the unweighted mean of the DES-T items.

Results: Overlapping, but not identical groups of patients were identified, indicating that the two methods are not interchangeable in this sample of personality disordered individuals. Surprisingly, no associations were detected between indices of childhood trauma and membership in the pathological dissociation taxon nor for the high dissociators identified through the approximation method.

Conclusions: This study serves as a replication of the ability to detect pathological dissociation as measured by the DES-T. Nonetheless, the failure to confirm our hypotheses regarding an association between pathological dissociation, childhood trauma, and personality diagnosis raise a challenge to some parts of existing etiologic theories.     

Viscoelastic Relaxation and Recovery of Tendon

Tendons exhibit complex viscoelastic behaviors during relaxation and recovery. Recovery is critical to predicting behavior in subsequent loading, yet is not well studied. Our goal is to explore time-dependent recovery of these tendons after loading. As a prerequisite, their strain-dependent viscoelastic behaviors during relaxation were also characterized. The porcine digital flexor tendon was used as a model of tendon behavior. Strain-dependent relaxation was observed in tests at 1, 2, 3, 4, 5, and 6% strain. Recovery behavior of the tendon was examined by performing relaxation tests at 6%, then dropping to a low but nonzero strain level. Results show that the rate of relaxation in tendon is indeed a function of strain. Unlike previously reported tests on the medial collateral ligament (MCL), the relaxation rate of tendons increased with increased levels of strain. This strain-dependent relaxation contrasts with quasilinear viscoelasticity (QLV), which predicts equal time dependence across various strains. Also, the tendons did not recover to predicted levels by nonlinear superposition models or QLV, though they did recover partially. This recovery behavior and behavior during subsequent loadings will then become problematic for both quasilinear and nonlinear models to correctly predict.

Dissociation as a Mediator of the Relationship Between Childhood Trauma and Nonsuicidal Self-Injury in Females: A Path Analytic Approach

New theoretical models of nonsuicidal self-injury (NSSI) postulate that symptoms subsequent to childhood maltreatment rather than childhood maltreatment itself may lead to engagement in NSSI. However, little is known concerning which specific syndromes serve as underlying mechanisms. In this study we sought to examine the mediating effects of dissociative, posttraumatic, and depressive symptoms, 3 often comorbid syndromes following childhood trauma. In addition, we aimed to assess differences between women with and without NSSI. A sample of 87 female inpatients with a history of childhood abuse and neglect was divided into 2 subgroups (NSSI: n = 42, no NSSI: n = 45). The assessment included measures of NSSI characteristics; adverse childhood experiences; and posttraumatic, dissociative, and depressive symptoms. The NSSI group reported significantly more cases of childhood maltreatment and higher levels of current dissociative, posttraumatic, and depressive symptoms than patients without NSSI. The results of a path analysis showed that only dissociation mediated the relationship between a history of child maltreatment and NSSI when all 3 psychopathological variables were included in the model. The findings point toward a strong and rather specific association between dissociative experiences and NSSI and therefore have important implications for clinical practice.
