Despite common experiences of identity damage, decline, and deterioration, many brain injury survivors succeed in reconstructing robust identities in the wake of injury. Yet, while this accomplishment greatly benefits survivors’ quality of life, little is known about how positive identity work might be facilitated or enhanced in therapeutic institutions. Drawing on data from a women’s self-help group, we argue that an egalitarian, reflective, strength-focused, and gender-segregated environment can provide female ABI (acquired brain injury) survivors with a fertile scene for identity enhancement and offer unique opportunities for collective identity development. Sociolinguistic interactional analysis revealed four types of positive identity work undertaken within the group: constructing competent selves; tempering the threat of loss and impairment; resisting infantilisation and delegitimisation; and asserting a collective gender identity. This identity work was facilitated by specific programme attributes and activities and contributed to the global project of decentring disability and destigmatising impairments and losses. We call for increased attention to identity issues in brain injury rehabilitation and argue that gender-segregated programming can provide a unique space for female survivors to construct empowering individual and collective identities after injury. 相似文献

Fos Expression in the Rat Brain Following Vaginal-Cervical Stimulation by Mating and Manual Probing 总被引:4,自引:2,他引:2

Vaginal-cervical stimulation (VCS), provided by mating or manual probing, induces many reproductive behavioral and endocrine changes in female rats. These changes include an increase in lordosis duration, heat termination and pseudopregnancy. Electro-physiological and [14C]2-deoxy-D-glucose studies collectively show that neurons in the medial preoptic area, ventromedial hypothalamus and midbrain central gray respond to manual VCS. In the present study we immunocytochemically labeled brain sections for Fos, the protein product of the immediate early gene c-fos, to detect VCS-responsive neurons in hormone-primed animals receiving VCS by mating or manual probing. In Experiment 1, females receiving mounts and intromissions were compared to: 1) vaginally-masked females receiving mounts but no VCS, 2) females exposed to an intact anesthetized male or 3) females not exposed to males or the testing arena. Those animals receiving VCS showed a dramatic increase in the number of Fos-immunoreactive cells in the medial preoptic area, posterodorsal portion of the medial amygdala and bed nucleus of the stria terminalis, as well as the dorsomedial hypothalamus, ventromedial hypothalamus and midbrain central gray. These effects of VCS were confirmed in Experiment 2 in animals receiving manual vaginal-cervical probing. These findings extend previous electrophysiological and [14C]2-deoxy-D-glucose studies by providing evidence that additional brain areas respond to VCS by mating, as well as manual probing. 相似文献

原发女性生殖道恶性黑色素瘤21例临床分析 总被引:2,自引:0,他引:2
目的探讨原发性女性生殖道恶性黑色素瘤的临床特点、治疗及预后。方法回顾分析本院1986年1月至2006年3月收治的原发性女性生殖道恶性黑色素瘤患者21例。其中外阴8例、阴道10例、阴道及宫颈1例、外阴及阴道1例、盆腔1例。结果患者中位年龄50(21~71)岁。临床表现主要为阴道流血、流液及发现外阴或阴道肿物。本资料阴道恶性黑色素瘤发病率高于外阴恶性黑色素瘤。按照国际妇产科联盟(FIGO)分期,期别和预后呈负相关。治疗以手术为主,手术方式由根治性切除逐渐衍变为扩大局部切除。随访:21例患者中随访率为67%(14/21),随访时间6~96个月,死亡7例,随访期间的死亡率为50%。结论女性生殖道恶性黑色素瘤发病率低,预后差。肿瘤厚度和淋巴结转移是其主要的危险因素。应采用手术基础上的综合治疗,治疗方案个体化。 相似文献

Although the prevalence of a learned voiding dysfunction and non-neurogenic neurogenic bladder (NNB), which is one type of dysfunctional elimination syndrome, is considered to be relatively rare, the association of NNB with Down syndrome (DS) has been elucidated in male patients. We herein describe the occurrence of NNB in an adult female with DS. The diagnosis was confirmed after completely ruling out any neurological or anatomical anomalies that could be related to a lower urinary tract dysfunction. She had renal dysfunction and multiple obstructive uropathies for which clean intermittent catheterization was successfully introduced. 相似文献
