NCT ID: NCT04797663 Completed - Keratosis Pilaris Clinical Trials

Long-pulsed 1064 nm Nd-YAG Laser Versus TCA 20% in Treatment of Keratosis Pilaris

Start date: March 17, 2021
Phase: Phase 4
Study type: Interventional

Keratosis pilaris (KP) is a common disorder of keratinization. There are different treatment modalities for KP with variable results. Nd:YAG laser and chemical peels are among these treatment modalities, however, there is no enough evidence in the literature regarding their efficacy. The aim of this study is to assess and compare the efficacy of long pulsed Nd:YAG laser and trichloreacetic acid 20% in treatment of keratosis pilaris.

NCT ID: NCT03855631 Completed - Kabuki Syndrome 1 Clinical Trials

Exploiting Epigenome Editing in Kabuki Syndrome: a New Route Towards Gene Therapy for Rare Genetic Disorders

Epi-KAB
Start date: September 28, 2020
Phase:
Study type: Observational

Starting from isolating primary cells from affected patients, an in vitro disease model system for KS will be developed. Using alternative strategies to obtain patient-derived mesenchymal stem cells, an integrative approach will be adopted for defining both the transcriptional and epigenetic regulatory networks perturbed upon the loss of function of KMT2D. Combining the self-renewal potential of mesenchymal stem cells (MSCs) with CRISPR/Cas9 technology, an epigenome editing approach as therapeutic strategy to rescue the activity of MLL4 will be developed. A step forward is expected towards the understanding of those the molecular mechanisms governing the aetiology of Kabuki Syndrome (KS) and that the proposed in vitro disease model will provide to the scientific community an experimental system to study the KS. Importantly, the aim is to define the molecular bases of KS and to develop a therapeutic strategy that could ameliorate some of the abnormalities associated with KS.

NCT ID: NCT02504502 Completed - Autism Clinical Trials

Enhancing Genomic Laboratory Reports to Enhance Communication and Empower Patients

Start date: August 2015
Phase: N/A
Study type: Interventional

Current lab reports are designed to communicate results from the laboratory to the provider; they are not designed to be accessible to patients. The investigators believe that a new type of genomic test report, tailored for patient- as well as provider-use, will enable patients to have access to information they can understand allowing them to be more involved in the management of their disorders, better navigate the health care system, and make more informed decisions about their health and health care in conjunction with their providers. This approach has the potential to improve outcomes from both the patient and provider perspectives. The investigators propose to study the research question, "Can a genomic laboratory report tailored for both providers and families of patients improve interpretation of complex results and facilitate recommended care by enhancing communication and shared decision making?"

NCT ID: NCT02451761 Completed - Clinical trials for Intellectual Disability

Apparently Balanced Chromosomal Translocation/ Next-generation Sequencing/ Intellectual Disability

ANI
Start date: April 2015
Phase: N/A
Study type: Observational

Apparently balanced chromosomal rearrangement (ABCR) associated with an abnormal phenotype is a rare but problematic event. It occurs in 6% of de novo reciprocal translocations and 9% of de novo inversions. Abnormal phenotype, including intellectual disability and / or multiple congenital anomalies (ID/MCA) may be explained either by associated cryptic genomic imbalances detectable by array-CGH or by gene disruption at the breakpoint. However, breakpoint cloning using conventional methods (i.e., fluorescent in situ hybridization (FISH), Southern blot) is often laborious and time consuming and cannot be performed routinely. Without complete investigation of these rearrangements, genetic counseling is a real challenge. Recently, the investigators and others showed that Next-Generation Sequencing (NGS) is a powerful and rapid technique to characterize ABCR breakpoints at the molecular level. The ANI project (ABCR NGS ID) aims at characterizing at the molecular level ABCR in 55 patients presenting with intellectual disability and/or multiple congenital anomalies (ID/MCA) using NGS. The investigators make the hypothesis that ABCR account for the patient phenotype, either by gene disruption or position effect, since genomic imbalance would have been previously excluded by array-Comparative Genomic Hybridization (CGH). The ANI project is a 3-year-long study that will be conducted by a consortium of 21 partners, including 19 french hospital cytogenetics laboratories, a research team (TIGER), and a cellular biotechnology center. Patients will be recruited by each Cytogenetics laboratory. ABCR breakpoints will be molecularly characterized by NGS and a first bio-informatics analysis. The results will be verified by amplification of junction fragments by polymerase Chain Reaction (PCR) followed by Sanger sequencing, allowing the localization of breakpoints at the base-pair level. In some complex cases, FISH experiment will be necessary to clarify the results. A second bio-informatics analysis will then determine breakpoints' characteristics (sequence, repeated elements, gene and regulatory elements). Finally, for each breakpoint, gene expression studies will be performed including the gene disrupted by the breakpoint and two neighboring genes. All these data, together with those already available in the literature and databases will be integrated to determine if the gene could account for the patient's phenotype, allowing an appropriate genetic counseling. This project will identify new candidate genes involved in ID and developmental anomalies. It will also contribute to the development and evaluation of NGS as a diagnostic tool for ABCR and ID/MCA. It will also allow unraveling mechanisms and functional consequences of ABCR, in particular in term of position effect. In conclusion, the ANI project will contribute to the improvement of diagnostic management and genetic counseling of patients with ID/MCA and ABCR. It will also contribute to the understanding of ABCR physiopathology and to the unraveling of pathway involved in development and brain function, thus improving genetic counseling for ID/MCA patients in general.

NCT ID: NCT01281644 Completed - Clinical trials for Keratosis Pilaris (KP)

Treatment of Keratosis Pilaris With 810 nm Diode Laser

KP
Start date: March 2011
Phase: N/A
Study type: Interventional

The investigators hope to establish whether or not the diode laser, a longer-wavelength laser, is effective in treating keratosis pilaris, and hopefully opening a door into the discussion and management of this skin condition. The primary outcome of interest is the difference in the overall blind rater severity scores of the treated versus the untreated sites. The secondary outcome of interest is the change in the patient's self-rated severity score of the treated site. To account for potential natural disease progression or regression, the investigators will also compare patient mean changes to the mean changes in severity scores of the untreated site.

NCT ID: NCT00955370 Completed - Clinical trials for Multiple Abnormalities

The Experience of Uncertainty in Parents of Children With an Undiagnosed Medical Condition

Start date: August 4, 2009
Phase: N/A
Study type: Observational

Background: - Rare and undiagnosed conditions are often chronic and disabling, with symptoms affecting different organ systems at various levels of severity. Perhaps the most challenging feature of an undiagnosed medical condition that has lasted 2 or more years is its characteristic uncertainty. In the absence of a diagnosis, health care professionals can provide only limited treatment and prognostic information. - In the case of a child with an undiagnosed condition, the uncertainty that accompanies what is often a chronic, debilitating medical condition and an undefined prognosis may have physical, psychological, social, and spiritual implications for the entire family. Research suggests that parents of a child with an undiagnosed medical condition may be at significantly increased risk of anxiety, depression, poor health, and overall lower quality of life. - It is not well understood how individuals cope with and adapt to chronic uncertainty, and the factors that influence this process. To design future interventions, descriptive studies are needed to reveal predictors that can be manipulated to improve outcomes. Objectives: - To examine whether perceptions of uncertainty, and perceived personal control, are associated with coping and adaptation. - To examine how the length of time elapsed since child was identified as sick and perceptions of uncertainty affect coping and adaptation. - To assess how perceptions of uncertainty, time elapsed since child became sick, optimism, and perceived personal control affect coping and adaptation. Eligibility: - Parents (older than 18 years of age) of children who have an undiagnosed medical condition. - Participants must have a working e-mail address or fixed postal address. Design: - Parents will be recruited from Web-based support networks for parents of undiagnosed children through Web site postings, electronic mailing lists, and printed newsletter postings. - Participants will be asked to complete a questionnaire about their experiences in living with a child who has an undiagnosed but chronic medical condition. The main outcome variable is adaptation to living with one's child's undiagnosed medical condition. - Participants have the option to complete an online or paper version of the questionnaire. The questionnaire should take between 20 and 30 minutes to complete. - No medical treatments are specifically offered as a part of this study.
