Filter by:Nodding Syndrome is an enigmatic neuropsychiatric syndrome affecting children and adolescents mostly in Eastern Africa. The symptoms of Nodding Syndrome and catatonia seem to overlap. The researchers' objectives in this study were to investigate the presence and types of catatonic symptoms in children with Nodding Syndrome and observe their response to one or two doses of lorazepam, the first-line treatment for catatonia.
The purpose of this clinical Study is TJCS Eye Drops 0.05%(Cyclosporine ophthalmic nano-emulsion) group and Restasis Eye Drops 0.05%(Cyclosporine ophthalmic suspension) group 12 weeks after treatment, each treatment group comparisons for evaluation of efficacy and safety in Moderate to Severe Dry Eye Disease.
The purpose of this study is to comprehensively characterize PMS using standardized medical, cognitive, and behavioral measures and to track the natural history of the syndrome using repeated longitudinal assessments. In addition, this study will be aiming to identify biomarkers using neuroimaging, including diffusion tensor imaging and identify genetic factors which contribute to diverse phenotypes in patients with PMS.
Klinefelter syndrome is characterized by primary testicular failure and progressive infertility. The objective of this study is to determine if sperm are present and can be observed in semen samples of adolescent and young adult Klinefelter patients and to determine whether the presence of sperm correlates with physical and/or clinically obtained hormone measures of pubertal development. This study was designed in order to answer the following questions: 1. Is it possible to retrieve sperm for cryopreservation from semen samples of adolescent and young adult Klinefelter patients? 2. Does the presence of sperm correlate with the physical and/or endocrine measures that are assessed during routine clinical evaluations of pubertal development in the KS patient population? 3. If sperm retrieval is possible, what is the optimal age at which sperm retrieval should be attempted?
Patients with PFPS demonstrate quadriceps and hip musculature weakness, altered lower extremity (LE) kinematics, and decreased LE flexibility. Psychosocial factors have also been identified as an important factor in patients with PFPS. The authors hypothesize that an ordered approach addressing each of these impairments sequentially will result in greater improvement in PFPS symptoms. The results of the investigators pilot study assessing the feasibility of using a sequential approach showed a full randomized controlled trial is warranted, the authors now plan to proceed with a full trial. The objective of this study is to assess the efficacy of a sequential approach in the treatment of Patellofemoral Pain Syndrome. Methods: Patients will be randomized to a sequential treatment approach using a PFPS treatment algorithm (PFPS Algorithm) designed by the authors or typical physical therapy care. Due to the constant evaluation necessary no blinding will be performed. Patients will attend therapy two times per week for six weeks. Pain, Anterior Knee Pain Scale (AKPS), and Global Rating of Change (GROC) will be measured at evaluation and discharge, 3 month follow-up and 6 month follow-up.
AIMS To study the effects of the decrease in iron tissue depots after scheduled bloodletting on insulin sensitivity, carbohydrate metabolism, classic and non-classic cardiovascular risk factors in patients with functional hyperandrogenism (polycystic ovary syndrome & idiopathic hyperandrogenism) on standard treatment with combined oral contraceptives (COC) according to usual clinical practice. METHODOLOGY Open label, controlled, parallel, prospective study of 12 months of duration, with 2 randomized arms of follow-up: i) Intervention Group: Patients with functional hyperandrogenism on standard COC treatment randomly allocated to perform scheduled phlebotomies from the third month of treatment to the end of the study (3 times with a 3-month interval between them). ii) Control Group: Patients with functional hyperandrogenism on standard COC treatment randomly allocated to follow-up without bloodletting. The whole group of patients will undergo a comprehensive anthropometric and hormonal assessment, evaluation of classic cardiovascular risk factors (insulin sensitivity and carbohydrate metabolism after a standard oral glucose test- 75 g), lipid profile, ambulatory and office blood pressure monitoring, proinflammatory profile, oxidative stress status, autonomic function assessment, and iron-related metabolism parameters at baseline, after 3-month COC treatment and after reduction of iron tissue depots plus OC in the Intervention Group of patients, and throughout follow-up under treatment with COC in the Control Group of patients. If a significant relationship between circulating hepcidin levels and elevated ferritin concentrations is observed, a study of the potential influence of mutations/polymorphic variants of hepcidin gene on ferritin values will be performed as well.
Polycystic Ovary Syndrome (PCOS) affects 5 to 10% of women of reproductive age. It is characterized by a cluster of hyperandrogenism, hyperinsulinemia, menstrual dysfunction, hirsutism and infertility. Although the pathogenesis of PCOS is unknown, accumulating evidence suggests that the dysregulation of some angiogenic factors, such as transforming growth factor-β (TGF-β) and vascular endothelial growth factor (VEGF), may be implicated. TGF-βs and VEGF exert a diverse range of biological functions regulating cell proliferation, angiogenesis, fibroblast activation and tissue fibrosis. PCOS ovaries show all the hallmarks of TGF-β and VEGF upregulation, including increased collagen deposition in ovarian stroma and theca, supported by increased vascularity. Consistent with this, The investigators recently showed that TGF-β1 is increased in serum of PCOS women while its circulating receptor soluble endoglin (sENG) is decreased, resulting in greater TGF-β1 bioavailability. Furthermore, it has been shown that women with PCOS have increased VEGF levels in the serum and/or follicular fluid. PCOS patients also have decreased vitamin D levels, and vitamin D treatment has been previously shown to improve various clinical parameters in PCOS women, including glucose intolerance, hypertension and androgen levels. Interestingly, vitamin D has been shown to decrease TGF-β1 and VEGF levels in several diseases, including myelofibrosis and various human cancer cells. Therefore, the investigators hypothesize that vitamin D treatment of PCOS women will result in a decrease of serum TGF-β1 levels and/or VEGF levels concomitant with improvement in clinical disease parameters. In addition, the investigators hypothesize that improvement in clinical disease parameters will correlate with changes in serum VEGF levels and TGF-β1 bioavailability. Our aim in the present study is to investigate the effects of vitamin D treatment on serum VEGF and TGF-β1/sENG levels in PCOS women, and assess whether changes in these angiogenic factors following vitamin D treatment correlate with clinical disease in these women. For this end, PCOS patients who are vitamin D-deficient will be treated with vitamin D and their serum levels of VEGF, TGF-β1 and its sENG receptor will be measured before and after treatment. In addition, clinical disease parameters will be recorded before and 4 months after treatment, including serum glucose and insulin levels, serum androgen levels, and blood pressure. The proposed study aims to identify a putative link between vitamin D, VEGF, and TGF-β1 in the context of PCOS, and provide a novel molecular explanation for the beneficial clinical effects of vitamin D on PCOS patients.

Constipation is a common condition among patients with Guillain-Barré Syndrome. It is believed, that the constipation is caused by autonomic neuropathy. However, the severity of the constipation, and its relation to autonomic function have not previously been studied.
The general consensus in sports medicine demonstrates a graduated return to activity protocol for individuals with post-concussion syndrome. This is commonly practiced but there is insufficient literature to indicate evidence-based practice. This study will provide evidence of the effectiveness of the clinical gradual return to exercise protocols beginning after diagnosis of post-concussion syndrome through standardization and measurement of outcomes.
