Active clinical trials for "Dissociative Disorders"

The purpose of this observational study is to measure the efficacy of a specific combined treatment (psychotherapy and pharmacotherapy) on patients with dissociative disorders, in terms of patients with a favorable outcome by means of the Dissociative Experiences Scale (DES).

Currently there is no technique to produce thin (0.004-0.01 mm) serial sections of large fresh tissue specimens that are suitable for high-resolution in situ protein/gene expression studies without ice artifact or fixation-induced molecular damage. Traditional frozen sectioning preserves protein and nucleic acid structure, but the inherent ice artifact precludes reconstruction of protein and mRNA expression patterns in 3-dimensions. Since the limitations of the existing sectioning techniques result from the fact that they rely on mechanical cutting which in turn require the tissue to be stiff, we suggest a new approach to cut tissue via an electro erosion process that utilizes focus radio frequency (RF).

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population. The aim of this multicenter study is to document the presence and/or post-operative development of posterior vitreous detachment (PVD) and to assess its influence on the incidence of retinal detachment (RD) in myopes in a time period of three and five years after lens surgery. 618 eyes of patients scheduled for regular lens surgery will be included, defined by an axial length of 25.0 mm or more. To examine the vitreous status, all patients will receive a comprehensive eye examination pre-operatively, including funduscopy with assessment of a Weiss ring and optical coherence tomography (OCT). Patients will be divided into two groups, group A with pre-operative complete PVD and group B with no/partial PVD. Group A will be invited for one follow-up visit (two months post-operatively) followed up by telephone interviews at one, two, three and five years after surgery to determine occurrence of pseudophakic retinal detachment. Group B will be invited for follow -up examinations at two months, six months and one year after surgery to document occurrence of PVD (if a PVD is present at one of the follow-ups, no more visits are necessary). Two, three and five years after surgery, all patients from group B will be interviewed by telephone, as in group A, to document the occurrence of pseudophakic retinal detachment. In the recent literature the association between the occurrence of PVD pre-/post-operative and RD after lens surgery is well documented but not described for myopic patients. The results of this multicenter study should help to tackle the problem of RD prediction in myopic patients depending on their pre-operative vitreous status, especially in the setting of refractive lens exchange.

Patients are required to position prior to retinal detachment surgery. We seek to see whether there is a correlation between the performed positioning and retinal detachment progression/regression in fovea-on retinal detachment patients.

The goal of the project is to investigate the prevalence of dissociative disorders in psychiatric inpatients in Taiwan. Relevant clinical issues, including common psychiatric comorbidity (e.g., positive psychotic symptoms), associated psychosocial factors (e.g., negative life events, perceived parenting style), and neuro-cognitive underpinning (e.g., executive functions) were also targeted. Standardized interview schedules, self-report scales, and cognitive tasks will be applied. The investigators hypothesized that dissociative disorders would be associated with positive psychotic symptoms, a history of early interpersonal adversity, and enhanced executive functions.

Lumbopelvic fixation is the treatment opation for spinopelvic dissociation. In our study we will compare unilateral versus bilateral lumbopelvic fixation as regarding functional outcomes by Majeed score along a period of 12vmonths as a primary measure and metal failure,skin condition and nonunion as secondaries.

Posterior vitreous detachment is a common event. With optical coherence tomography, the investigators can precisely follow the stage of posterior vitrous detachment. In this study, the investigators investigate if the loss of contact between the vitreous and the fovea is the start of glaucoma progression.
