Filter by:We use Transcranial magnetic stimulation (TMS), combined with simultaneous registration of electroencephalograph (EEG),for examining human cortical functionality. TMS-EEG is a noninvasive brain stimulation method that allows to study human cortical function in vivo. EEG provides an opportunity to directly measure the cerebral response to TMS, measuring the cortical TMS Evoked potential (TEP). In this study we measure TEPs, in a wide variety of neurological conditions and healthy as a measure of cerebral reactivity across wide areas of neocortex.
This study is an 8-week pilot trial with oxytocin nasal spray (Syntocinon) as a treatment for social impairment in children and adults with high functioning autism spectrum disorders (ASD). The investigators hypothesize that oxytocin will be safe, tolerable, and effective in improving social deficits in individuals with ASD.
This is a single site, prospective, randomized, double-blind study of a single intravenous autologous or allogeneic, unrelated cord blood (CB) infusion in children ages 2-7 years with Autism Spectrum Disorder (ASD). Participants will be randomly assigned to Sequence A, consisting of a single infusion of CB cells at baseline followed 6 months later by a single infusion of placebo, or Sequence B, consisting of an infusion of placebo at baseline followed 6 months later by an infusion of CB cells. All participants will ultimately be treated with CB cells at some point during the study. Participants with an available qualified autologous CB unit will receive autologous cells, and those without a suitable autologous CB unit available will receive cells from a ≥4/6 HLA-matched, ABO-matched allogeneic, unrelated donor CB unit from the Carolinas Cord Blood Bank. All infusions will be double-blinded. The primary outcomes will be assessed 6 months after the initial infusion in the sequence. Additional testing for secondary exploratory analyses will be performed at 12 months. Duration of study participation will be 12 months from the time of baseline infusion.
Photodynamic diagnostic (PDD) is a technique where a photodynamic drug is installed preoperatively in the bladder. Mucosa cells with a higher metabolism than normal urothelial cells, e.g. cancer cells, absorbs this drug which is utilized during cystoscopy where blue light is absorbed by the drug, making the surgeon able to distinguish tumor cells from normal cells and thus being able to identify flat lesions and small papillomas missed in white light cystoscopy. The use of PDD at this primary transurethral resection of bladder tumour (TURB) has been shown to be associated with a lower recurrence rate within the first year, probably mostly owing to a higher detection rate of small papillomas and dysplasia that therefore can be relevantly treated at an early stage. Despite the use of PDD at the primary TURB, a high number of patients experience an early recurrence and patients with carcinoma in situ (CIS) treated with bacillus Calmette-Guerin (BCG) may have recurrence of their CIS or recurrence of papillomas despite the peroperative use of PDD. Whereas the use of PDD is well established in the TURB setting, the use of PDD in the follow-up setting with flexible cystoscopy in the outpatient clinic is not investigated. Feasibility studies have been successful but the clinical relevance and benefits have not been investigated so far. Thesis The thesis of the study is that the use of PDD in the outpatient clinic in patients with a high recurrence risk undergoing follow-up flexible cystoscopy will result in diagnosis of papillomas earlier than by the use of conventional flexible cystoscopy in white light. Thus, a higher number of tumours can be treated in the outpatient setting without the need for procedures in general anesthesia. Furthermore, the number of follow-up cystoscopies can be reduced if PDD is used at the first cystoscopy following TURB. Aims To investigate whether the use of PDD when performing a flexible cystoscopy in the outpatient clinic can reduce the number of recurrences of large size papillomas that cannot be treated by simple fulguration without general anesthesia. Furthermore, to investigate whether the use of PDD in follow-up cystoscopy in patients with earlier complete response to BCG on CIS, can increase the detection rate of CIS recurrences.
This study is an 8-week open-label trial testing oxytocin nasal spray (Syntocinon) as a treatment for social impairment in adolescents with autism spectrum disorders (ASD). We hypothesize that oxytocin nasal spray will be safe, tolerable, and effective in improving the core symptoms of autism spectrum disorders in adolescents ages 11-17.
As the use of video games (VG) is rapidly increasing, many studies have tries to understand the effects of VG on the children and adolescents playing them. Most of the research was directed towards negative effects (especially violence, attention and school performance), producing mixed results. Recently, more studies had focused their attention on the opposite angle: The influence of the player's mental and behavioral parameters, influencing his VG playing patterns. The focus of most of these researches was time of playing, addictive patterns and exposure to violence. The current study will try to characterize the variance of VG playing pattern among adolescents diagnosed with psychiatric disorders, in order to better under the rich interaction between a player and his VG, and to understand whether VG playing patterns holds diagnostical clues for the child's diagnosis and his inner world.
