Filter by:Congenital malformations correspond to defects in organ morphogenesis identifiable at birth or intrauterine life, affecting 2-3% of births. Inside of these malformations, Congenital Heart Disease corresponds, in particular, to structural defects of the heart or major blood vessels thereof may or may not be associated with other types of syndromes.The resolution is usually surgical. Also, these patients present a decrease in physical fitness, psychological imbalance, lower quality of life and risk significant morbidity and mortality from respiratory infections among other problems. This can have severe consequences for health in the medium and long term. The habits acquired during childhood and adolescence are determinant for the adult life, being relevant levels of activity and physical condition, especially in children with pathologies. In this way, it is vital to know from childhood parameters that indicate the baseline state of these patients according to the levels of physical activity, exercise capacity, nutritional status and quality of life. These will be key indicators to take into account in the future, to adapt rehabilitation plans that will reduce the effects of their condition. The objective of this protocol is To characterize the levels of Activity, and Physical Capacity of children with congenital heart disease regularly treated at the Cardiovascular Center of Dr. Luis Hospital Calvo Mackenna, compared to healthy children matched by age and sex.
This study compares the accuracy of fusion imaging (Fusion Roadmap) versus real-time X-ray imaging (Roadmap) during catheterization of supra-aortic trunks of in patients with aneurysms or arteriovenous malformations.
With the ongoing developments in the field of hysteroscopy during the past 15 years, hysteroscopic surgery is becoming safer and less invasive for the patient. Improved technology has enabled surgeons to perform many operative procedures in an ambulatory setting without significant patient discomfort and with potentially significant cost savings. Office operative hysteroscopy (see and treat hysteroscopy) reduces the distinction between a diagnostic and an operative procedure, shifting the focus in health care away from inpatient diagnosis and treatment. The development of smaller-diameter hysteroscopes with continuous-flow system features and working channels, through which operative instruments can be introduced, has made it possible to treat some uterine and cervical diseases without the traditional need for cervical dilation or general anesthesia. Use of specially designed hysteroscopic 5F mechanical instruments (e.g., scissors, biopsy cup, graspers, and corkscrews) has long been the only way to perform operative procedures in an ambulatory setting. However, although grasping forceps and scissors are excellent for treating adhesions, cervical polyps, and endometrial polyps smaller than or the same size as the larger endometrial polyps, or thick lesions (e.g., submucous fibroids) were difficult to treat successfully using such miniature, fragile instruments and without cervical dilation. An important technologic advance occurred in 1997 with the introduction of a versatile bipolar electrosurgery system dedicated to hysteroscopy, the Gynecare VersaPoint (Ethicon, Inc., Somerville, NJ, USA), which represents a key point in the history of office operative hysteroscopy. With the use of 5F bipolar electrodes, the number of pathologic conditions treated using office operative hysteroscopy has increased tremendously, reducing the use of the resectoscope and the operating room to a smaller number of cases. More recently, a new generation of electrical generators, allowing the use of bipolar energy on miniaturized electrodes, has been presented (Autocon 400 II; Karl Storz Endoscopy, Tuttlingen, Germany). The main advantage of these instruments is that they are reusable, thereby reducing the costs of office operative as those described for the Versapoint system. The feasibility of ambulatory uterine surgery is not just dependent on recent technological advances in instrumentation such as miniaturization of equipment, but also the favorable anatomical characteristics of the uterus itself. The sensitive innervations of the uterus originate in the myometrium and extend to the outer serosal surface, whereas the endometrium and any fibrotic tissue within the cavity are less sensitive. Thus, procedures can be carried out without the use of analgesia or anesthesia. However, a careful operative technique is of paramount importance, in particular, avoiding inadvertent deep penetration of the superficial myometrium when resecting lesions such as polyps, maintaining the lowest possible distension pressures, and expediting procedures through efficient surgical techniques.
Co morbidity rates of hearing loss in children with autism spectrum disorder are high and increasing. Investigators are aiming to: 1. evaluate peripheral auditory and brain stem auditory function in children with autism spectrum disorder. 2. compare communication capabilities in autistic children having hearing abnormalities and autistic children with normal hearing.
To evaluate the efficacy of Rapamycin in extended cervicofacial lymphatic malformations in pediatric patients. Rapamycin is administered oral for a 6 month period. The success rate is determined by volume reduction superior to 1/5e of the initial volume measured by MRI, impact on QOL and reduction of bleeding in case of mucosal involvement.
Melasma is a commonly pigmention characterized by melanotic patches on the face. literature searched revealed that periodontitis and vitamin D deficiency have occurred along with anemia. Actinic associated factors may be indirectly related to vitamin D, melasma contributes to sun exposed area of face.To correlate melasma with clinical evidence of periodontitis and vitamin D serum analysis along side hb %. Patients with facial melasma between 30-70yrs of either gender formed Group A (95). Anaemia and periodontitis were Clinically checked. Additionally serum analysis of vitamin D and hb percentage were analysed. Similar procedure was carried out on controls which had Group B (95) patients with no melasma on face. The study revealed significant correlation between melasma and periodontitis with vitamin D abnormalities (p value<.05), where as insignificant correlation between melasma and Hb%. The correlation between melasma, vitamin d changes and periodontitis may prompt the clinician to check for any such changes in any patient. Melasma in patients with periodontitis and serum vitamin D changes might be a considered as a syndrome.
Transcranial contrast-enhanced ultrasound for evaluation of cerebral blood flow during pediatric cardiac surgery. This study is aimed as a feasibility study prior to conducting a lager prospective clinical trial including neurologic and developmental outcome measures.
The Ma'anshan Birth Cohort (MABC) is a population-based prospective pregnancy and birth cohort study that aims to explore the early environmental and genetic determinants of maternal and child health, with a focus on health outcomes including maternal health, children's cognitive and behavioral development, growth and physical development, video-screen behaviors, and asthma and allergic diseases. MABC was officially launched in May 2013 at the Ma'anshan Maternal and Child Health Hospital in Anhui Province, and a total of 3,474 families were recruited as of September 2014 to continuously track the health status of mother-child pairs during pregnancy, delivery, and childhood, including basic family demographics, maternal pregnancy and birth history and past history, history of exposure to hazardous factors during pregnancy, children's diets and lifestyles, and children's physical and cognitive-behavioral development, MABC quantifies the attributional relationship between environmental chemicals, diet and nutrition, drug safety, psychological stress, lifestyle, biorhythm, endocrine metabolism and adverse birth outcomes, birth defects, neurodevelopmental disorders, developmental disabilities, etc., and identifies environmental, behavioral and genetic causative factors for birth defects and common developmental disorders, and identifies early warning signs and symptoms for early detection of birth defects. genetic causative factors, identify clinical biomarkers with early predictive effects, integrate and form a precise risk evaluation and early warning model, carry out regional comprehensive prevention and treatment applications, and promote the improvement of the quality of the birth population. Currently, MABC is conducting its 20th school-age follow-up visit.
To evaluate the clinical benefits and risks of hybrid operating techniques in management of cerebral arteriovenous malformations.
In approximately half of individuals with Down syndrome, an higher than normal number of vessels cross the optic disc margin. Investigator hypothesize that early retinal vessel branching occurs due to inhibition of angiogenesis by triplet overexpression of endostatin, an angiogenesis inhibitor encoded on chromosome 21. Since angiogenesis is critical in the development of eyes and other organs angiogenesis depended (specially kidney, brain, and recently described lungs and heart), early branching of retinal vessels at the level of the optic disc would also likely result in abnormal renal and other organs development in these individuals. Investigator wish to determine whether observation of optic disc vessels may serve as an indicator of elevated endostatin levels and other angiogenesis-dependent organs anomalies.
