    Oxygen consumption (VO(2) ) is an important part of hemodynamics using the direct Fick principle in children undergoing cardiac catheterization. Accurate measurement of VO(2) is vital. Obviously, any error in the measurement of VO(2) will translate directly into an equivalent percentage under- or overestimation of blood flows and vascular resistances. It remains common practice to estimate VO(2) values from published predictive equations. Among these, the LaFarge equation is the most commonly used equation and gives the closest estimation with the least bias and limits of agreement. However, considerable errors are introduced by the LaFarge equation, particularly in children younger than 3 years of age. Respiratory mass spectrometry remains the "state-of-the-art" method, allowing highly sensitive, rapid and simultaneous measurement of multiple gas fractions. The AMIS 2000 quadrupole respiratory mass spectrometer system has been adapted to measure VO(2) in children under mechanical ventilation with pediatric ventilators during cardiac catheterization. The small sampling rate, fast response time and long tubes make the equipment a unique and powerful tool for bedside continuous measurement of VO(2) in cardiac catheterization for both clinical and research purposes.

    Electrical impedance tomography (EIT) can determine ventilation and perfusion relationship. Most of the data obtained so far originates from experimental settings and in healthy subjects. The aim of this study was to demonstrate that EIT measures the perioperative changes in pulmonary blood flow after repair of a ventricular septum defect in children with haemodynamic relevant septal defects undergoing open heart surgery. In a 19 bed intensive care unit in a tertiary children's hospital ventilation and cardiac related impedance changes were measured using EIT before and after surgery in 18 spontaneously breathing patients. The EIT signals were either filtered for ventilation (ΔZV) or for cardiac (ΔZQ) related impedance changes. Impedance signals were then normalized (normΔZV, normΔZQ) for calculation of the global and regional impedance related ventilation perfusion relationship (normΔZV/normΔZQ). We observed a trend towards increased normΔZV in all lung regions, a significantly decreased normΔZQ in the global and anterior, but not the posterior lung region. The normΔZV/normΔZQ was significantly increased in the global and anterior lung region. Our study qualitatively validates our previously published modified EIT filtration technique in the clinical setting of young children with significant left-to-right shunt undergoing corrective open heart surgery, where perioperative assessment of the ventilation perfusion relation is of high clinical relevance.

    Sixteen children with hematological disease who had undergone allogeneic stem cell transplantation (SCT) were evaluated to determine the adverse effect of anthracycline (ATC) and cyclophosphamide (CY) used as the conditioning regimen on pre- and post-transplant cardiac function. Methods employed were resting electrocardiogram (ECG), echocardiography and {sup 123}I-BMIPP (beta-methyl-iodophenyl-pentadecanoic acid) imaging. A cumulative ATC dose over 300 mg/m{sup 2}, especially over 400 mg/m{sup 2}, was predictable for pre-transplant abnormal findings by parameters such as uptake score (US) and heart mediastinum ratio (H/M). However, the cumulative ATC dose and pre-transplant mild abnormal cardiac findings did not correlate with post-transplant cardiac function. A 200 mg/kg dose of CY was predictable for decreased summated QRS amplitude (QRS sum) and left ventricular mass index (LVMI), however, there was no correlation between the CY dose and the values obtained through BMIPP imaging. Moreover, the CY dose was not a risk factor for worsening post-transplant fractional shortening (FS) as evaluated by echocardiography. In summary, {sup 123}I-BMIPP imaging was useful for evaluating subclinical cardiac damage due to ATC before transplant, but not for predicting cardiac damage during the course of SCT. (author)

    Children diagnosed with congenital heart disease often undergo cardiac catheterization for their treatment, which involves the use of ionizing radiation and therefore a risk of radiation-induced cancer. The purpose of this study was to calculate the effective and equivalent organ doses (H{sub T}) in those children and estimate the risk of exposure-induced death. Fifty-three children were divided into three groups: atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). In all procedures, the exposure conditions and the dose-area product meters readings were recorded for each individual acquisition. Monte Carlo simulations were run using the PCXMC 2.0 code and mathematical phantoms simulating a child's anatomy. The H{sub T} values to all irradiated organs and the resulting E and risk of exposure-induced death values were calculated. The average dose-area product values were, respectively, 40 {+-} 12 Gy.cm{sup 2} for the ASD, 17.5 {+-} 0.7 Gy.cm{sup 2} for the VSD and 9.5 {+-} 1 Gy.cm{sup 2} for the PDA group. The average E values were 40 {+-} 12, 22 {+-} 2.5 and 17 {+-} 3.6 mSv for ASD, VSD and PDA groups, respectively. The respective estimated risk of exposure-induced death values per procedure were 0.109, 0.106 and 0.067%. Cardiac catheterizations in children involve a considerable risk for radiation-induced cancer that has to be further reduced. (orig.)

  10. Cardiac tumours in children

    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

    Full Text Available In recent years, the number of patients undergoing cardiac surgeries is steadily increasing. In Greece, approximately 10,500 patients per year are admitted to some kind of cardiac operation. Constant evolution of heart surgery techniques calls for adaptation of the perioperative nursing care given. Patient education, as an important part of the perioperative care, is directly related to the reduction of postoperative complications and stress management, thus promoting the patient's overall postoperative well-being. Aim: The aim of this review was to present the most important aspects of the patient's perioperative education and the role that the nurse has to play in it. Methods: Data from selected articles were extracted from Pubmed, Chinahl and Cohrane, as well as from non-electronically published scientific studies ranging from 1998-2010 and 2003-2008 respectively. Results: According to the literature, perioperative patient education can be implemented in various ways, such as through verbal updates, the use of audiovisual means and the provision of informative leaflets. The teaching topics can be divided into those of the preoperative and postoperative phase. Stress management prepares the patients psychologically and also enhances the therapeutic nurse-patient relationship. The teaching of breathing techniques and isometric exercises of the lower limbs, the cessation of smoking, the diet to be followed, as well as the management of medication, aim in the patients' physical preparation, in order to optimize their postoperative course. Conclusion: Perioperative patient education, regardless of how it is implemented, constitutes both an integral part of the nursing care and an independent nursing intervention per se, which strengthens the nurses' autonomy and improves the patient's postoperative course.

Its incidence is higher in immunocompromised hosts than in the general population. In children and during hemodialysis, TB is characterized by the frequency of extrapulmonary localizations and diagnostic difficulties. The aim of this retrospective study is to evaluate the incidence of TB in Tunisian children undergoing hemodialysis and to determine its clinical features as well as the results of chemotherapy.Method: This retrospective study includes seven TB children among 112 children on hemodialysis at the pediatric nephrology department in Charles Nicolle Hospital from 2002 to 2008. The diagnosis of TB was established by a combination of clinical, radiological, biochemical, microbiological, and histological examinations. Treatment with anti-TB drugs, the results of therapy, and the outcome of patients were noted.Results: There were four girls and three boys aged 10 to 16 years (mean, 13 years. They had been on hemodialysis for 2 to 5 years (mean, 3 years. Noted clinical features were weight loss and fever in five cases, chest pain in one case, cervical lymph node in one case, and spinal pain in one case. The organ systems involved were pleural in two cases, pulmonary in one case, peritoneal in one case, cervical lymphatic in one case, and spinal in one case. One patient was treated empirically with a good response. Diagnosis was made by isolation of mycobacterium TB in three cases, by specific histological signs observed in a lymph node biopsy in one case, in peritoneal biopsy in one case, and in discovertebral biopsy in one case. In the remaining patient, the clinical and radiological presentations were compatible with pulmonary TB. All patients received four anti-TB drugs: isoniazid, rifampicin, pyrazinamide

    In an attempt to determine whether noninvasive cardiac testing could be used to assess cardiac risk in patients undergoing surgery for vascular disease, the authors studied 96 patients. Seventy-seven patients eventually underwent major vascular surgery with 11 (14%) experiencing a significant cardiac complication. Thallium imaging was much more likely to be positive (p less than 0.01) in patients with a cardiac complication; however, there was a significant number of patients with cardiac complications who had a positive history or electrocardiogram for myocardial infarction. When grouped by complication and history of infarction, thallium imaging, if negative, correctly predicted low cardiac risk in the group with a history of infarction. Thallium imaging, however, did not provide a clear separation of risk in those without a history of infarction. Age and coronary angiography, on the other hand, did reveal significant differences within the group without a history of infarction. The resting radionuclide ejection fraction followed a similar pattern to thallium imaging. It is concluded that a positive history of myocardial infarction at any time in the past is the strongest risk predictor in this population and that the predictive value of noninvasive testing is dependent on this factor. Considering these findings, a proposed scheme for assessing risk that will require further validation is presented.

    Although red blood cells(RBCs) transfusion is sometimes associated with adverse reactions,anemia could also lead to increased morbidity and mortality in highrisk patients. For these reasons,the definition of perioperative strategies that aims to detect and treat preoperative anemia,prevent excessive blood loss,and define "optimal" transfusion algorithms is crucial. Although the treatment with preoperative iron and erythropoietin has been recommended in some specific conditions,several controversies exist regarding the benefit-to-risk balance associated with these treatments. Further studies are needed to better define the indications,dosage,and route of administration for preoperative iron with or without erythropoietin supplementation. Although restrictive transfusion strategies in patients undergoing cardiac surgery have been shown to effectively reduce the incidence and the amount of RBCs transfusion without increase in side effects,some high-risk patients(e.g.,symptomatic acute coronary syndrome) could benefit from higher hemoglobin concentrations. Despite all efforts made last decade,a significant amount of work remains to be done to improve hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery.

  18. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization

    Science.gov (United States)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

    2012-02-01

    AIMS AND OBJECTIVES: To identify the information needs of children undergoing tonsillectomy with reference to content of information, method of delivery, information providers and timing of information provision. BACKGROUND: Tonsillectomy can be anxiety provoking for children and preoperative preparation programmes are long recognised to reduce anxiety. However, few have been designed from the perspectives of children and to date little is known about how best to prepare children in terms of what to tell them, how to convey information to them, who can best provide information and what is the best timing for information provision. DESIGN: A qualitative descriptive study. METHOD: Data were collected from nine children (aged 6-9) using interviews supported by a write and draw technique. Data were coded and categorised into themes reflecting content, method, providers and timing of information. RESULTS: Children openly communicated their information needs especially on what to tell them to expect when facing a tonsillectomy. Their principal concerns were about operation procedures, experiencing \\'soreness\\' and discomfort postoperatively and parental presence. Mothers were viewed as best situated to provide them with information. Children were uncertain about what method of information and timing would be most helpful to them. CONCLUSION: Preoperative educational interventions need to take account of children\\'s information needs so that they are prepared for surgery in ways that are meaningful and relevant to them. Future research is needed in this area. RELEVANCE TO CLINICAL PRACTICE: Practical steps towards informing children about having a tonsillectomy include asking them what they need to know and addressing their queries accordingly. Child-centred information leaflets using a question and answer format could also be helpful to children.

The objective of our study was to evaluate the correlation between continuous ScvO2 by the application of a fiber-optic oximetry catheter (PediaSat and intermittent ScvO2 by using standard blood gas measurements. These results were compared to those obtained by cerebral near infrared spectroscopy (cNIRS. Setting: Tertiary pediatric cardiac intensive care unit (PCICU. Methods and main results: A retrospective study was conducted in consecutive patients who were monitored with a 4.5 or 5.5 F PediaSat catheter into the right internal jugular vein. An in vivo calibration was performed once the patient was transferred to the PCICU and re-calibration took place every 24 hours thereafter. Each patient had a NIRS placed on the forehead. Saturations were collected every 4 hours until extubation. Ten patients with a median age of 2.2 (0.13-8.5 years and a weight of 12.4 (3.9-24 kg were enrolled. Median sampling time was 32 (19-44 hours: 64 pairs of PediaSat and ScVO2 saturations showed a poor correlation (r=0.62, 95% CI 44-75; p<0.0001 and Bland Altman analysis for repeated measures showed an average difference of 0.34 with a standard deviation of 7,9 and 95% limits of agreement from -15 to 16. Thirty-six pairs of cNIRS and ScVO2 saturations showed a fair correlation (r=0.79, 95% CI 0.60-0.89; p<0.0001 an average difference of -1.4 with a standard deviation of 6 and 95% limits of agreement from -13 to 10. Analysis of median percentage differences between PediaSat and ScvO2 saturation over time revealed that, although not statistically significant, the change in percentage saturation differences was clinically relevant after the 8th hour from calibration (from -100 to +100%. Conclusion: PediaSat catheters showed unreliable performance in our cohort. It should be further investigated whether repeating

    Cardiac surgery for congenital heart disease often necessitates a period of myocardial ischemia during cardiopulmonary bypass and cardioplegic arrest, followed by reperfusion after aortic cross-clamp removal. In experimental models, myocardial ischemia-reperfusion is associated with significant oxidative stress and ventricular dysfunction. A prospective observational study was conducted in infants (tetralogy of Fallot (TOF). Blood samples were drawn following anesthetic induction (baseline) and directly from the coronary sinus at 1, 3, 5, and 10 min following aortic cross-clamp removal. Samples were analyzed for oxidant stress using assays for thiobarbituric acid-reactive substances, protein carbonyl, 8-isoprostane, and total antioxidant capacity. For each subject, raw assay data were normalized to individual baseline samples and expressed as fold-change from baseline. Results were compared using a one-sample t test with Bonferroni correction for multiple comparisons. Sixteen patients (ten with TOF and six with VSD) were enrolled in the study, and there were no major postoperative complications observed. For the entire cohort, there was an immediate, rapid increase in myocardial oxidative stress that was sustained for 10 min following aortic cross-clamp removal in all biomarker assays (all P < 0.01), except total antioxidant capacity. Infant cardiac surgery is associated with a rapid, robust, and time-dependent increase in myocardial oxidant stress as measured from the coronary sinus in vivo. Future studies with larger enrollment are necessary to assess any association between myocardial oxidative stress and early postoperative outcomes. PMID:26843460

    Full Text Available Background. Psychiatric comorbidity is common in patients with cardiovascular disease, with the literature indicating that this population may be at risk for apathy. The current study examined the prevalence of apathy in patients with cardiovascular disease and its relation to aspects of cognitive function. Methods. 123 participants from an outpatient cardiology clinic completed a brief neuropsychological battery, a cardiac stress test, and demographic information, medical history, and depression symptomatology self-report measures. Participants also completed the Apathy Evaluation Scale to quantify apathy. Results. These subjects reported limited levels of apathy and depression. Increased depressive symptomatology, history of heart attack, and metabolic equivalents were significantly correlated with apathy (P<0.05. Partial correlations adjusting for these factors revealed significant correlations between behavioral apathy and a measure of executive function and the other apathy subscale with a measure of attention. Conclusion. Findings revealed that apathy was not prevalent in this sample though associated with medical variables. Apathy was largely unrelated to cognitive function. This pattern may be a result of the mild levels of cardiovascular disease and cognitive dysfunction in the current sample. Future studies in samples with severe cardiovascular disease or neuropsychological impairment may provide insight into these associations.

    Background Awareness under general anesthesia is a serious complication which leads to psychiatric disorders. The incidence of awareness in patients undergoing cardiac surgery has been reported in as many as 1.5%-23% in foreign countries. But so far, medical literature about awareness during cardiac surgery is still rare in China. Therefore, we investigated the incidence of awareness in patients undergoing different kinds of cardiac surgery, the phases when awareness occured and the effect of cardiopulmonary bypass on the incidence of awareness in coronary artery bypass grafting in Beijing.Methods Patients' recall of awareness during cardiac surgery was assessed. One hundred patients undergoing coronary artery bypass grafting (CABG) in Chaoyang Hospital, Beijing, one hundred patients undergoing CABG and one hundred patients undergoing valve replacement or septal defect repair in Fuwai Hospital, Beijing, were interviewed 3-6 days after surgery. Every report obout patients on recall of awareness was recorded. An independent research team, blinded to patients' surgery and anesthesia, assessed every report of awareness.Results The incidence of awareness of patients received CABG under cardiopulmonary bypass (CPB), off -pump CABG, septal repair or valve replacement under CPB was 4.7% (5 of 106 cases), 9.6% (9 of 94 cases) and 4% (4 of 100 cases), respectively. CPB did not greatly affect the incidence of awareness during the period of CABG (P>0.05). The incidence of awareness of patients who received CABG under CPB did not increase significantly, in comparison with that of patients who received septal repair or valve replacement under CPB in Fuwai Hospital (P>0.05). Awareness easily occurred before bypass grafting or CPB.Conclusions Awareness mainly occurs before bypass grafting or CPB in cardiac surgery. Most cases with awareness have auditory perceptions. CPB is not a main factor which affects the incidence of awareness of CABG. Surgical types do not affect the

The aim of this study was to evaluate the role of pulmonary rehabilitation before and after surgery for reducing the risk of pulmonary complications after surgery also correlations of the six-minute walk test and respiratory following open heart surgery. Material and Methods — In a randomized clinical trial, 60 patients undergoing heart surgery were divided into two groups randomly (groups A and B. In group A it was performed physiotherapy before and after chest physiotherapy surgery, but on patients in group B were done only chest physiotherapy after surgery. Effects of preoperative pulmonary rehabilitation were compared between two groups, using spirometry and six-minute walk test. Results — Thirty nine of males (65% and 21 females (35% with a mean age of 8.10±9.56 was been analyzed. The mean difference in predicted forced vital capacity (CI95%: 1.3 to 8.7 and predicted peak flow indices (CI95%: 1.9 to 9.4 of spirometery indicator was significant, also evaluation of six-minute walk test showed, mean difference in walking distant (CI95%: 8.8 to 21.0 and mean oxyhemoglobin saturation (CI95%: 0.59 to 1.67 in group A was more than group B. Inverse correlation of heart rate with forced vital capacity showed that patients with more restriction had more heart rate during the walking test. Conclusion — Pulmonary rehabilitation program before surgery is recommended to reduce complications of heart surgery. Further evaluations are necessary in relation to the sensitivity and specificity of six-minute walk test parameters alone in the evaluation of respiratory performance.

  15. Evaluation of effective dose received by patients undergoing Cardiac Angiography Computed Tomography (CT) and Conventional Angiography

    International Nuclear Information System (INIS)

    Cardiac Angiography is a field of studies that utilizes the energy of radiation to study the coronary arteries of the heart. Patients undergoing this procedure has a probability of receiving an over dose of radiation that may further cause stochastic effect. The main objective of this research is to compare and clarify an approach for minimal effective dose receive by patients between procedures of Cardiac Angiography Computerized Tomography (CT) and Conventional Angiography. Based on this study, the patients recorded are based in Hospital University Sains Malaysia, Kubang Kerian, Kelantan. The Dose-Length-Product (DLP) was extracted from the Computed Tomography Dose Index (CTDI); meanwhile the Dose-Area-Product (DAP) was extracted from the modalities console screen. These relevant data are the means to clarify the effective dose receive by patients. The result shows that patients who undergo Conventional Angiography had a mean effective dose of 8.50 ± 6.41 mSv. Meanwhile, as for Cardiac Angiography Computerized Tomography, the patients had a mean effective dose of 7.08 ± 2.42 mSv. A significant difference in effective dose was seen between the two procedures. Cardiac Angiography CT provides high accurate diagnostic information with less radiation dose to patients compared to Conventional Angiography. (author)

  17. Utility of an Australasian registry for children undergoing radiation treatment

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

  18. Cardiac catheterization in infants and children

    International Nuclear Information System (INIS)

    Cardiac catheterization in infants and children allows a unique opportunity to study physiologic effects of simple and complex lesions in a population with almost invariably normal coronary arteries. While morbidity from catherization is low and mortality is almost negligible in older infants and children, the risks are higher among infants under the age of 4 months, many of whom are seriously ill at the time of the study. In recent years there has been an increase in therapeutic procedures undertaken in the catheterization laboratory such as dilatation of stenotic valves and vessels. There has also been an increase in the use of such diagnostic techniques as electrophysiological studies and endomyocardial biopsies. Catheterization and these newer techniques, particularly in the young infant, should be undertaken only by physicians and technicians experienced in this field, using the best equipment available

    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

Cobalamin (vitamin B12 deficiency is a common cause of neuropsychiatric symptoms and affects up to 40% of elderly people. The relationship between cobalamin deficiency and the occurrence of delirium after cardiac surgery has not been examined in previous studies. We examined the relationship between cobalamin deficiency and delirium in elderly patients undergoing coronary artery bypass grafting (CABG surgery.Material and methods: A total of 100 patients with cobalamin deficiency undergoing CABG were enrolled in this retrospective study. Control group comprised 100 patients without cobalamin deficiency undergoing CABG. Patients aged 65 years or over were included. Diagnosis of delirium was made using Intensive Care Delirium Screening Checklist. Delirium severity was measured using the Delirium Rating Scale-revised-98.Results: Patients with cobalamin deficiency had a significantly higher incidence of delirium (42% vs 26%; P=0.017 and higher delirium severity scores (16.5±2.9 vs 15.03±2.48; P=0.034 than patients without cobalamin deficiency.

    Background: Patients with significant bilateral carotid artery stenosis requiring urgent cardiac surgery have an increased risk of stroke and death. The optimal management strategy remains inconclusive, and the available evidence does not support the superiority of one strategy over another. Materials and Methods: A number of noninvasive strategies have been developed for minimizing perioperative stroke including continuous real-time monitoring of cerebral oxygenation with near-infrared spectroscopy (NIRS). The number of patients presenting with this combination (bilateral significant carotid stenosis requiring urgent cardiac surgery) in any single institution will be small and hence there is a lack of large randomized studies. Results: This case series describes our early experience with NIRS in a select group of patients with significant bilateral carotid stenosis undergoing urgent cardiac surgery (n = 8). In contrast to other studies, this series is a single surgeon, single center study, where the entire surgery (both distal ends and proximal ends) was performed during single aortic clamp technique, which effectively removes several confounding variables. NIRS monitoring led to the early recognition of decreased cerebral oxygenation, and corrective steps (increased cardiopulmonary bypass flow, increased pCO2, etc.,) were taken. Conclusion: The study shows good clinical outcome with the use of NIRS. This is our “work in progress,” and we aim to conduct a larger study. PMID:26750675

    Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients≥70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze-pam (25 mg/5 mg) or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess-ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients’ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale (VAS). The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer’s Assessment of Alertness/Sedation Scale (OAA/S). Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients’ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group (P < 0.05 for both). Nurses reported an improvement with patient management in the pre-medicated group (P=0.08). Conclusions In conclusion, premedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

    Anxiety about and fear of dental treatment have been recognized as sources of problems in the management of child dental patients. It has been suggested that some individuals who are fearful of or anxious about dental treatment have a constitutional vulnerability to anxiety disorders as is evidenced by the presence of multiple fears, generalized anxiety or panic disorders. Concerning the child population, maternal anxiety is considered to be a major factor affecting the behaviour of young children expecting dental intervention. The aim of the study was to the measure general anxiety of children undergoing dental intervention and to compare it with some personality characteristics, such as psychopathology, extroversion and neuroticism. The evaluated sample comprises 50 children (31 girls and 19 boys), randomly selected at the University Dental Hospital, Skopje. The mean age for girls was 11.4 (± 2.4) years, and for boys 10.7 (± 2.6) years. Two psychometric instruments were used: the General Anxiety Scale for Children (GASC) and the Eysenck Personality Questionnaire (EPQ). The study confirms the presence of a high anxiety level (evaluated with GASC) among all children undergoing dental intervention. It also confirmed differences in anxiety scores between girls and boys, girls having higher scores for anxiety. Personality characteristics (evaluated with EPQ) showed low psychopathological traits, moderate extroversion and neuroticism, but accentuated insincerity (evaluated with L scale). L scales are lower with increasing age, but P scores rise with age, which could be related to puberty. No correlation was found between personality traits (obtained scores for EPQ) and anxiety except for neuroticism, which is positively correlated with the level of anxiety. In the management of dental anxiety some response measures (psychological support, biofeedback, and relaxation techniques) are recommended. PMID:24566020

    Standard care of burn wounds consists of cleaning and debridement (removing devitalized tissue), followed by daily dressing changes. Children with burns undergo multiple, painful and anxiety-provoking procedures during wound care and rehabilitation. The goal of procedural sedation is safe and efficacious management of pain and emotional distress, requiring a careful and systematic approach. Achieving the best results needs understanding of the mechanisms of pain and the physiologic changes in burn patients, frequent evaluation and assessment of pain and anxiety, and administration of suitable pharmacological and nonpharmacological therapies. Pharmacological therapies provide the backbone of analgesia and sedation for procedural pain management. Opioids provide excellent pain control, but they must be administered judiciously due to their side effects. Sedative drugs, such as benzodiazepines and propofol, provide excellent sedation, but they must not be used as a substitute for analgesic drugs. Ketamine is increasingly used for analgesia and sedation in children as a single agent or an adjuvant. Nonpharmacological therapies such as virtual reality, relaxation, cartoon viewing, music, massage and hypnosis are necessary components of procedural sedation and analgesia for children. These can be combined with pharmacological techniques and are used to limit the use of drugs (and hence side effects), as well as to improve patient participation and satisfaction. In this article, we review the pathophysiologic changes associated with major thermal injury in children, the options available for sedation and analgesia for wound care procedures in these children and our institutional guidelines for procedural sedation.

    Thomas Gremmel

    Full Text Available Plasma soluble CD40 ligand (sCD40L is mainly generated by cleavage of CD40L from the surface of activated platelets, and therefore considered a platelet activation marker. Although the predictive value of sCD40L for ischemic events has been demonstrated in patients with acute coronary syndromes (ACS, studies on the association of sCD40L with cardiovascular outcomes in lower risk populations yielded heterogeneous results. We therefore sought to investigate factors influencing sCD40L levels, and the predictive value of sCD40L for long-term ischemic events in unselected, aspirin-treated patients undergoing cardiac catheterization. sCD40L was determined by a commercially available enzyme-linked immunosorbent assay in 682 consecutive patients undergoing cardiac catheterization. Two-year follow-up data were obtained from 562 patients. Dual antiplatelet therapy with aspirin and clopidogrel was associated with significantly lower levels of sCD40L and lower platelet surface expressions of P-selectin and activated GPIIb/IIIa compared to aspirin monotherapy (all p≤0.01. Hypertension was linked to lower plasma concentrations of sCD40L, whereas female sex, increasing high-sensitivity C-reactive protein, and hematocrit were associated with higher sCD40L concentrations (all p<0.05. sCD40L levels were similar in patients without and with the primary endpoint in the overall study population (p = 0.4. Likewise, sCD40L levels did not differ significantly between patients without and with the secondary endpoints (both p≥0.4. Similar results were obtained when only patients with angiographically-proven coronary artery disease (n = 459, stent implantation (n = 205 or ACS (n = 125 were analyzed. The adjustment for differences in patient characteristics by multivariate regression analyses did not change the results. ROC curve analyses did not reveal cut-off values for sCD40L for the prediction of the primary or secondary endpoints. In conclusion, plasma sCD40L

    BACKGROUND: Studies on the relationship between left ventricular reverse remodeling and cardiopulmonary exercise capacity in heart failure patients undergoing cardiac resynchronization therapy (CRT) are scarce and inconclusive. METHODS AND RESULTS: Eighty-four patients with a 1st-time CRT......-defibrillator (mean age 65 ± 11; 73% male) underwent echocardiography and cardiopulmonary exercise testing (CPX) before implantation (baseline) and 6 months after implantation. At baseline, patients also completed a set of questionnaires measuring mental and physical health. The association between echocardiographic...... echocardiographic responders showed improvements in ventilatory efficiency during follow-up. Multivariable repeated measures analyses revealed that, besides reverse remodeling, New York Heart Association functional class II and good patient-reported health status before implantation were the most important...

  13. Predicted risks of radiogenic cardiac toxicity in two pediatric patients undergoing photon or proton radiotherapy

    International Nuclear Information System (INIS)

    Hodgkin disease (HD) and medulloblastoma (MB) are common malignancies found in children and young adults, and radiotherapy is part of the standard treatment. It was reported that these patients who received radiation therapy have an increased risk of cardiovascular late effects. We compared the predicted risk of developing radiogenic cardiac toxicity after photon versus proton radiotherapies for a pediatric patient with HD and a pediatric patient with MB. In the treatment plans, each patient’s heart was contoured in fine detail, including substructures of the pericardium and myocardium. Risk calculations took into account both therapeutic and stray radiation doses. We calculated the relative risk (RR) of cardiac toxicity using a linear risk model and the normal tissue complication probability (NTCP) values using relative seriality and Lyman models. Uncertainty analyses were also performed. The RR values of cardiac toxicity for the HD patient were 7.27 (proton) and 8.37 (photon), respectively; the RR values for the MB patient were 1.28 (proton) and 8.39 (photon), respectively. The predicted NTCP values for the HD patient were 2.17% (proton) and 2.67% (photon) for the myocardium, and were 2.11% (proton) and 1.92% (photon) for the whole heart. The predicted ratios of NTCP values (proton/photon) for the MB patient were much less than unity. Uncertainty analyses revealed that the predicted ratio of risk between proton and photon therapies was sensitive to uncertainties in the NTCP model parameters and the mean radiation weighting factor for neutrons, but was not sensitive to heart structure contours. The qualitative findings of the study were not sensitive to uncertainties in these factors. We conclude that proton and photon radiotherapies confer similar predicted risks of cardiac toxicity for the HD patient in this study, and that proton therapy reduced the predicted risk for the MB patient in this study

    The aim of this study was to determine the effect of choice of invasive monitoring on cost, morbidity, and mortality in cardiac surgery. Two hundred and twenty-six adults undergoing elective cardiac surgery were initially assigned at random to receive either a central venous pressure monitoring catheter (group I), a conventional pulmonary artery (PA) catheter (group II), or a mixed venous oxygen saturation (SvO2) measuring PA catheter (group III). If the attending anesthesiologist believed that the patient initially randomized to group I should have a PA catheter, that patient was then reassigned to receive either a conventional PA catheter (group IV) or SvO2 measuring PA catheter (group V). The total costs were defined as the total amount billed to the patient for the catheter used; the professional cost of its insertion; and the determinations of cardiac output, arterial blood gas tensions, hemoglobin level, and hematocrit. Mean total monitoring and laboratory costs in Group I ($591 +/- 67) were statistically significantly (P less than 0.05) less than costs in Group II ($856 +/- 231). Further, mean monitoring and laboratory costs in Group II were statistically significantly (P less than 0.05) less than those in Group III ($1128 +/- 759). Patients in group IV incurred mean total costs of $986 +/- 578, while those in group V had mean total costs of $1126 +/- 382 (NS). There were no significant differences between any of the groups with respect to length of stay in the intensive care unit, morbidity, or mortality.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2505641

  15. Radiation Dose to the Thyroid and Gonads in Patients Undergoing Cardiac CT Angiography

    International Nuclear Information System (INIS)

    The present data show a global increase in the rate of cardiovascular disease. Cardiac CT angiography has developed as a fast and non-invasive cardiac imaging modality following the introduction of multi-slice computed tomogaraphy. The aim of this study was to measure the radiation dose to the thyroid and pelvis regions in patients undergoing cardiac CT angiography using the Care Dose 4D method of 64-slice scanner. Eighty-one patients (41 males and 40 females) who were diagnosed with suspected coronary artery disease and were referred to Golestan Hospital, Imaging Department were recruited. Inclusion criteria were based on the protocol of multi-slice CT coronary angiography. The radiation dose to the thyroid and pelvis regions was measured using thermo luminescent dosimeters (TLDs). The mean radiation dose to the thyroid in male and female subjects was 0.32 mSv and 0.41 mSv, respectively (P = 0.032) (total mean, 0.36 mSv). The mean radiation dose to the pelvis in male and female subjects was 81 μSv and 112 μSv, respectively (P = 0.026) (total mean, 96.5 μSv), The total mean radiation dose to the thyroid and gonads was 0.36 mSv, and 96.5 μSv, respectively for the subjects. These values were high for one organ in a single study. Gender can affect the radiation dose to the thyroid and gonads. This can be attributed to the anatomical characteristic differences of the male and female subjects

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery. PMID:25120320

  18. Coronary artery disease in patients undergoing valve replacement at a tertiary care cardiac centre

    International Nuclear Information System (INIS)

    To determine the prevalence of coronary artery disease in patients undergoing valve surgery at a tertiary care cardiac centre. The medical records of 144 consecutive patients who underwent mitral, aortic or dual (mitral and aortic) valve replacement surgery at the Tabba Heart Institute between January 2006 to December 2008 were retrospectively reviewed. All patients underwent coronary angiogram. Significant coronary artery disease (CAD) is defined as coronary stenosis of > 50%. There were 74 (51.4%) males and 70 (48.6%) females in the study. The mean age was 51.64 +- 11 years. Of all, 73 (50.7%) underwent mitral valve replacement, 47 (32.6%) had aortic and 24 (16.7%) had dual valve replacement. Out of 144 patients, 99 (68.8%) had 50% stenosis. In patients who had undergone mitral valve replacement (MVR), significant coronary disease was found in 32.9%, whereas in patients who had undergone aortic valve replacement (AVR) and dual valve replacement (DVR) the prevalence of coronary disease was 31.9% and 25% respectively. Our results suggest that the overall prevalence of coronary artery disease in patients undergoing valve surgery in our population is comparable with prevalence reported in international data.

  19. Non-invasive anesthesia for children undergoing proton radiation therapy

    International Nuclear Information System (INIS)

    Background: Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions. Purpose: Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia. Materials and methods: A retrospective review of anesthetic records for patients ⩽18 years of age treated with proton therapy at our institution between January 2006 and April 2013 was performed. Results: A total of 9328 anesthetics were administered to 340 children with a median age of 3.6 years (range, 0.4–14.2). The median daily anesthesia time was 47 min (range, 15–79). The average time between start of anesthesia to the start of radiotherapy was 7.2 min (range, 1–83 min). All patients received Total Intravenous Anesthesia (TIVA) with spontaneous ventilation, with 96.7% receiving supplemental oxygen by non-invasive methods. None required daily endotracheal intubation. Two episodes of bradycardia, and one episode each of; seizure, laryngospasm and bronchospasm were identified for a cumulative incidence of 0.05%. Conclusions: In this large series of children undergoing proton therapy at a freestanding center, TIVA without daily endotracheal intubation provided a safe, efficient, and less invasive option of anesthetic care

    This study aimed to verify whether psychologists and game activities could reduce preoperative anxiety and promote compliance in paediatric patients. More specifically, we sought to evaluate whether it would be better to propose contextualized games or just distracting activities. A total of 104 children undergoing surgery were assigned to the following 4 conditions of treatment: (1) contextual games and psychological accompaniment, (2) only contextual games, (3) distracting activities, and (4) only psychological accompaniment. Observed children's anxiety was assessed using modified Yale Preoperative Anxiety Scale and compliant behaviours with modified form of Induction Compliance Checklist. Children in the first condition (complete intervention - contextual games and psychological accompaniment) were less anxious and more cooperative in the preoperative period and during the induction of anaesthesia than in the other three conditions. In particular, contextual activities (second condition) were found to be more efficient than psychological accompaniment (fourth condition), whereas the worst condition was proposing only distracting activities (third condition). In order to help young hospitalized patients in paediatric surgery structures, it is necessary to propose games that can prepare them for what will happen as well as the support of a psychologist.

    Cardiac imaging plays an important role in both congenital and acquired heart diseases. Cardiac computed tomography (angiography) cCT(A) is a non-invasive, increasingly popular, complementary modality to echocardiography in evaluation of congenital heart diseases (CHD) in children. Despite radiation exposure, cCT(A) is now commonly used for evaluation of the complex CHD, giving information of both intra-cardiac and extra-cardiac anatomy, coronary arteries, and vascular structures. This review article will focus on the fundamentals and essentials for performing cCT(A) in children, including radiation dose awareness, basic techniques, and strengths and weaknesses of cCT(A) compared with cardiac magnetic resonance imaging (cMRI), and applications. The limitations of this modality will also be discussed, including the CHD for which cMRI may be substituted.

  3. Cardiac dual-source CT for the preoperative assessment of patients undergoing bariatric surgery

    International Nuclear Information System (INIS)

    Aim: To assess the diagnostic value of coronary dual-source computed tomography (DSCT) as a comprehensive, non-invasive tool in the preoperative cardiac evaluation of patients undergoing bariatric surgery. Materials and methods: Thirty consecutive obese [average body mass index (BMI): 45 ± 7.6, range: 35–59] patients (24 women; six men; median age: 52 ± 15 years) were enrolled in this institutional review board (IRB)-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant prospective study. Calcium scoring (CaS) and electrocardiography (ECG)-gated images of the coronary arteries were obtained with a large body habitus protocol (120 kV; 430 mAs; 100 ml iodinated contrast medium at 7 ml/s injection rate) on a DSCT machine. Qualitative (four-point: 1 = excellent to 4 = not delineable) coronary segmental analysis, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) measurements were performed. The presence and degree of vascular disease (four-grade scale: mild to severe) was correlated with CaS and cardiovascular (CV) risk stratification blood tests. In patients with severe stenosis (>70%), findings were compared with cardiac nuclear medicine imaging (single photon-emission computed tomography; SPECT) imaging. Results: The average HR, enhancement, and quality score were 64 ± 7 beats/min, 288 ± 66 HU and 1.8 ± .5, respectively. Ninety-three percent (417/450) of the coronary segments were rated diagnostic. The SNRs and CNRs were 17 ± 9 and 12 ± 7 for the right coronary artery; 17 ± 8 and 12 ± 7 for the left main coronary artery; 16 ± 9 and 11 ± 7 for the left anterior descending coronary artery; and 15 ± 7 and 10 ± 6 for the left circumflex coronary artery. Ten of the 30 patients (33%) demonstrated coronary artery disease (CAD) of which two (6%) showed three-vessel disease. Four (13%) patients showed severe disease: in three of which the presence of significant stenosis was confirmed by SPECT and by catheter

    Background and Objective. Pain evaluation in children can be a difficult task, since it possesses sensory and affective components that are often hard to discriminate. Infrared thermography has previously been used as a diagnostic tool for pain detection in animals; therefore, the aim of this study was to assess the presence of temperature changes during dental extractions and to evaluate its correlation with heart rate changes as markers of pain and discomfort. Methods. Thermographic changes in the lacrimal caruncle and heart rate measurements were recorded in healthy children scheduled for dental extraction before and during the procedure and compared. Afterwards, correlation between temperature and heart rate was assessed. Results. We found significant differences in temperature and heart rate before the procedure and during the dental extraction (mean difference 4.07°C, p < 0.001, and 18.11 beats per minute, p < 0.001) and no evidence of correlation between both measurements. Conclusion. Thermographic changes in the lacrimal caruncle can be detected in patients who undergo dental extractions. These changes appear to be stable throughout time and to possess very little intersubject variation, thus making them a candidate for a surrogate marker of pain and discomfort. Future studies should be performed to confirm this claim. PMID:27445611

    2008-01-01

    Full Text Available Background. Voiding cystourethrograms are distressing for children and parents. Nonpharmacological methods reduce distress. Pharmacological interventions for VCUG focus on sedation as well as analgesia, anxiolysis, and amnesia. Sedation has cost, time, and safety issues. Which agents and route should we use? Are we sure that sedation does not influence the ability to diagnose vesicoureteric reflux? Methods. Literature search of Medline, EMBASE, and the Cochrane Database. Review of comparative studies found. Results. Seven comparative studies including two randomised controlled trials were reviewed. Midazolam given orally (0.5-0.6 mg/kg or intranasally (0.2 mg/kg is effective with no apparent effect on voiding dynamics. Insufficient evidence to recommend other sedating agents was found. Deeper sedating agents may interfere with voiding dynamics. Conclusion. Midazolam reduces the VCUG distress, causes amnesia, and does not appear to interfere with voiding dynamics. Midazolam combined with simple analgesia is an effective method to reduce distress to children undergoing VCUG.

    Purpose: To demonstrate the dosimetric advantages of cardiac-sparing (CS) intensity modulated radiation therapy (IMRT) in children undergoing whole lung irradiation (WLI). Methods and Materials: Chest CT scans of 22 children who underwent simulation with 3-dimensional (n=10) or 4-dimensional (n=12) techniques were used for this study. Treatment planning was performed using standard anteroposterior-posteroanterior (S-RT) technique and CS-IMRT. Left and right flank fields were added to WLI fields to determine whether CS-IMRT offered any added protection to normal tissues at the junction between these fields. The radiation dose to the lung PTV, cardiac structures, liver, and thyroid were analyzed and compared. Results: CS-IMRT had 4 significant advantages over S-RT: (1) superior cardiac protection (2) superior 4-dimensional lung planning target volume coverage, (3) superior dose uniformity in the lungs with fewer hot spots, and (4) significantly lower dose to the heart when flank RT is administered after WLI. Conclusions: The use of CS-IMRT and 4-dimensional treatment planning has the potential to improve tumor control rates and reduce cardiac toxicity in children receiving WLI.

    In the healthy heart, left ventricular (LV) filling generates flow patterns which have been proposed to optimize blood transport by coupling diastole and systole phases. We present a novel image-based method to assess how flow patterns influence LV blood transport in patients undergoing cardiac resynchronization therapy (CRT). Solving the advection equation with time-varying inflow boundary conditions allows to track the transport of blood entering the LV in the different filling waves, as well as the transport barriers which couple filling and ejection. The velocity fields were obtained using echocardiographic color Doppler velocimetry, which provides two-dimensional time-resolved flow maps in the apical long axis three-chamber view of the LV. We analyze flow transport in a group of patients with CRT devices as well as in healthy volunteers. In the patients under CRT, the device programming was varied to analyze flow transport under different values of the atrioventricular (AV) conduction delay and to model tachycardia. This analysis illustrates how CRT influences the transit of blood inside the LV, contributes to conserving kinetic energy and favors the generation of hemodynamic forces that accelerate blood in the direction of the LV outflow tract.

    Full Text Available Background and objectives: In children undergoing congenital heart surgery, plasma brain natriuretic peptide levels may have a role in development of low cardiac output syndrome that is defined as a combination of clinical findings and interventions to augment cardiac output in children with pulmonary hypertension. Methods: In a prospective observational study, fifty-one children undergoing congenital heart surgery with preoperative echocardiographic study showing pulmonary hypertension were enrolled. The plasma brain natriuretic peptide levels were collected before operation, 12, 24 and 48 h after operation. The patients enrolled into the study were divided into two groups depending on: (1 Development of LCOS which is defined as a combination of clinical findings or interventions to augment cardiac output postoperatively; (2 Determination of preoperative brain natriuretic peptide cut-off value by receiver operating curve analysis for low cardiac output syndrome. The secondary end points were: (1 duration of mechanical ventilation ≥72 h, (2 intensive care unit stay >7days, and (3 mortality. Results: The differences in preoperative and postoperative brain natriuretic peptide levels of patients with or without low cardiac output syndrome (n = 35, n = 16, respectively showed significant differences in repeated measurement time points (p = 0.0001. The preoperative brain natriuretic peptide cut-off value of 125.5 pg mL−1 was found to have the highest sensitivity of 88.9% and specificity of 96.9% in predicting low cardiac output syndrome in patients with pulmonary hypertension. A good correlation was found between preoperative plasma brain natriuretic peptide level and duration of mechanical ventilation (r = 0.67, p = 0.0001. Conclusions: In patients with pulmonary hypertension undergoing congenital heart surgery, 91% of patients with preoperative plasma brain natriuretic peptide levels above 125.5 pg mL−1 are at risk of developing low cardiac

    Background: The identification of biomarkers for predicting morbidity and mortality, particularly in pediatric population undergoing cardiac surgery will contribute toward improving the patient outcome. There is an increasing body of literature establishing the clinical utility of hyperlactatemia and lactate clearance as prognostic indicator in adult cardiac surgical patients. However, the relationship between lactate clearance and mortality risk in the pediatric population remains to be established. Objective: To assess the role of lactate clearance in determining the outcome in children undergoing corrective surgery for tetralogy of Fallot (TOF). Methods and Study Design: A prospective, observational study. Setting: A tertiary care center. Study Population: Two hundred children undergoing elective surgery for TOF. Study Method: Blood lactate levels were obtained as baseline before operation (T0), postoperatively at admission to the cardiac intensive care unit after surgery (T1), and then at every 6 h for the first 24 h of Intensive Care Unit (ICU) stay (T6, T12, T18, and T24, respectively). The lactate clearance in the study is defined by the equation ([lactate initial – lactate delayed]/lactate initial) ×100%. Lactate clearance was determined at T1–T6, T1–T12, T1–T18, and T1–T24 time interval, respectively. The primary outcome measured was mortality. Secondary outcomes measured were the duration of mechanical ventilation, duration of inotropic requirement, and duration of ICU stay. Results: Eleven out of the two hundred patients enrolled in the study died. Nonsurvivors had higher postoperative lactate concentration (P 10%, relative to patients with a lactate clearance 10%) after 6 h have improved outcome compared with those with lower lactate clearance.

    Fetal and pediatric cardiac autopsies have a crucial role in the counseling of parents with regard to both the cause of death of their child and the implications of such findings for future pregnancies, as well as for quality assurance of antenatal screening programs and antemortem diagnostic procedures. Postmortem imaging allows an opportunity to investigate the heart in situ prior to dissection, and both postmortem CT and postmortem MRI have shown excellent accuracy in detecting the majority of clinically significant cardiac lesions in the perinatal and pediatric population. As less-invasive autopsy becomes increasingly popular, clinical guidelines for maximal diagnostic yield in specific circumstances can be developed. (orig.)

    The hierarchical interaction between electrical signals of the brain and heart is not fully understood. We hypothesized that the complexity of cardiac electrical activity can be used to predict changes in encephalic electricity after stress. Most methods for analyzing the interaction between the heart rate variability (HRV) and electroencephalography (EEG) require a computation-intensive mathematical model. To overcome these limitations and increase the predictive accuracy of human relaxing states, we developed a method to test our hypothesis. In addition to routine linear analysis, multiscale entropy and detrended fluctuation analysis of the HRV were used to quantify nonstationary and nonlinear dynamic changes in the heart rate time series. Short-time Fourier transform was applied to quantify the power of EEG. The clinical, HRV, and EEG parameters of postcatheterization EEG alpha waves were analyzed using change-score analysis and generalized additive models. In conclusion, the complexity of cardiac electrical signals can be used to predict EEG changes after stress.

    Background: Most congenital heart diseases (CHDs) have specific hemodynamics, including volume and pressure overload, as well as cyanosis and pulmonary hypertension, associated with anatomical abnormalities. Such hemodynamic abnormalities can cause activation of neurohormones, inflammatory cytokines, fibroblasts, and vascular endothelial cells, which in turn contribute to the development of pathologic conditions such as cardiac hypertrophy,fi brosis, and cardiac cell damages and death. Measuring biomarker levels facilitates the prediction of these pathological changes, and provides information about the stress placed on the myocardial cells, the severity of the damage, the responses of neurohumoral factors, and the remodeling of the ventricle. Compared to the ample information on cardiac biomarkers in adult heart diseases, data from children with CHD are still limited. Data sources: We reviewed cardiac biomarkers-specifi cally focusing on troponin as a biomarker of myocardial damage, amino-terminal procollagen type III peptide (PIIIP) as a biomarker of myocardialfi brosis and stromal remodeling, and B-type natriuretic peptide (BNP)/N-terminal proBNP as biomarkers of cardiac load and heart failure, by introducing relevant publications, including our own, on pediatric CHD patients as well as adults. Results: Levels of highly sensitive troponin I are elevated in patients with atrial septal defects (ASDs) and ventricular septal defects (VSDs). PIIIP levels are also elevated in patients with ASD, VSD, pulmonary stenosis, and Tetralogy of Fallot. Measurement of BNP and N-terminal proBNP levels shows good correlation with heart failure score in children. Conclusions: In the treatment of children with CHD requiring delicate care, it is vital to know the specifi c degree of myocardial damage and severity of heart failure. Cardiac biomarkers are useful tools for ascertaining the condition of CHDs with ease and are likely to be useful in determining the appropriate care of

    Full Text Available BACKGROUND: Sympathetic hyperactivity may be related to left ventricular (LV dysfunction and baro- and chemoreflex impairment in hypertension. However, cardiac function, regarding the association of hypertension and baroreflex dysfunction, has not been previously evaluated by transesophageal echocardiography (TEE using intracardiac echocardiographic catheter. METHODS AND RESULTS: We evaluated exercise tests, baroreflex sensitivity and cardiovascular autonomic control, cardiac function, and biventricular invasive pressures in rats 10 weeks after sinoaortic denervation (SAD. The rats (n = 32 were divided into 4 groups: 16 Wistar (W with (n = 8 or without SAD (n = 8 and 16 spontaneously hypertensive rats (SHR with (n = 8 or without SAD (SHRSAD (n = 8. Blood pressure (BP and heart rate (HR did not change between the groups with or without SAD; however, compared to W, SHR groups had higher BP levels and BP variability was increased. Exercise testing showed that SHR had better functional capacity compared to SAD and SHRSAD. Echocardiography showed left ventricular (LV concentric hypertrophy; segmental systolic and diastolic biventricular dysfunction; indirect signals of pulmonary arterial hypertension, mostly evident in SHRSAD. The end-diastolic right ventricular (RV pressure increased in all groups compared to W, and the end-diastolic LV pressure increased in SHR and SHRSAD groups compared to W, and in SHRSAD compared to SAD. CONCLUSIONS: Our results suggest that baroreflex dysfunction impairs cardiac function, and increases pulmonary artery pressure, supporting a role for baroreflex dysfunction in the pathogenesis of hypertensive cardiac disease. Moreover, TEE is a useful and feasible noninvasive technique that allows the assessment of cardiac function, particularly RV indices in this model of cardiac disease.

    Full Text Available Abstract Background Genetically engineered mouse models of human cardiovascular disease provide an opportunity to understand critical pathophysiological mechanisms. Cardiovascular magnetic resonance (CMR provides precise reproducible assessment of cardiac structure and function, but, in contrast to echocardiography, requires that the animal be immobilized during image acquisition. General anesthetic regimens yield satisfactory images, but have the potential to significantly perturb cardiac function. The purpose of this study was to assess the effects of general anesthesia and a new deep sedation regimen, respectively, on cardiac function in mice as determined by CMR, and to compare them to results obtained in mildly sedated conscious mice by echocardiography. Results In 6 mildly sedated normal conscious mice assessed by echo, heart rate was 615 ± 25 min-1 (mean ± SE and left ventricular ejection fraction (LVEF was 0.94 ± 0.01. In the CMR studies of normal mice, heart rate was slightly lower during deep sedation with morphine/midazolam (583 ± 30 min-1, but the difference was not statistically significant. General anesthesia with 1% inhaled isoflurane significantly depressed heart rate (468 ± 7 min-1, p In mice with ischemic LV failure, ejection fraction measurements were comparable when performed during light sedation, deep sedation, and general anesthesia, respectively. Contrast-to-noise ratios were similar during deep sedation and during general anesthesia, indicating comparable image quality. Left ventricular mass measurements made by CMR during deep sedation were nearly identical to those made during general anesthesia (r2 = 0.99, mean absolute difference Conclusion In mice with normal cardiac function, CMR during deep sedation causes significantly less depression of heart rate and ejection fraction than imaging during general anesthesia with isoflurane. In mice with heart failure, the sedation/anesthesia regimen had no clear impact on

    The tolerability of a 2.5% lidocaine/prilocaine hydrogel (Nanorap, Biolab Indústria Farmacêutica Ltd., Sao Paulo, Brazil) was evaluated in 20 children ages 2 to 11 years undergoing cryotherapy for molluscum contagiosum (MC). The product was well tolerated, with only two children presenting with eczema at the application site. These adverse reactions were considered unlikely to be related to the test product, because a patch test was negative in one of the individuals and the other event occurred in only one of the two treated areas. Nanorap is an efficacious and well-tolerated option for topical anesthesia in children undergoing cryotherapy for MC. PMID:27041686

    Pineal cysts, both simple and complex, are commonly encountered in children. More cysts are being detected with MR technology; however, nearly all pineal cysts are benign and require no follow-up. To discover the prevalence of pineal cysts in children at our institution who have undergone high-resolution 3-T MRI. We retrospectively reviewed 100 consecutive 3-T brain MRIs in children ages 1 month to 17 years (mean 6.8 ± 5.1 years). We evaluated 3-D volumetric T1-W imaging, axial T2-W imaging, axial T2-W FLAIR (fluid attenuated inversion recovery) and coronal STIR (short tau inversion recovery) sequences. Pineal parenchymal and cyst volumes were measured in three planes. Cysts were analyzed for the presence and degree of complexity. Pineal cysts were present in 57% of children, with a mean maximum linear dimension of 4.2 mm (range 1.5-16 mm). Of these cysts, 24.6% showed thin septations or fluid levels reflecting complexity. None of the cysts demonstrated complete T2/FLAIR signal suppression. No cyst wall thickening or nodularity was present. There was no significant difference between the ages of children with and without cysts. Cysts were more commonly encountered in girls than boys (67% vs. 52%; P = 0.043). There was a slight trend toward increasing pineal gland volume with age. Pineal cysts are often present in children and can be incidentally detected by 3-T MRI. Characteristic-appearing pineal cysts in children are benign, incidental findings, for which follow-up is not required if there are no referable symptoms or excessive size. (orig.)

    Ever since percutaneous endoscopic gastronomy (PEG) was used for the first time in 1980 by Gauderer, Ponsky, Izant et al., It has been widely used in patients incapable of oral feeding. It is a safe and effective technique for long-term nutritional support in children, and easy to perform, as only local anesthesia or heavy sedation is required PEG can prevent children from suffering from nasopharyngeal and esophageal erosions due to repeated insertion of nasogastric tubes and the complication of aspiration pneumonia. It is therefore an alternative for children who need long-term feeding. In this article we review the literature on PEG and give a full description of its indications, complications, as well as advice on when to change gastrostomy tubes, and on nursing care, in the hope that this will be useful reference material for medical staff.

    We report the case of successful resuscitation after prolonged cardiac arrest during orthotopic liver transplantation. After reperfusion, the patient developed ventricular tachycardia, complicated by intracardiac clot formation and massive hemorrhage. Transesophageal echocardiography demonstrated stunned and nonfunctioning right and left ventricles, with developing intracardiac clots. Treatment with heparin, massive transfusion and prolonged cardiopulmonary resuscitation ensued for 51 minutes. Serial arterial blood gases demonstrated adequate oxygenation and ventilation during cardiopulmonary resuscitation. Cardiothoracic surgery was consulted for potential use of extracorporeal membrane oxygenation, however, the myocardial function improved and the surgery was completed without further intervention. On postoperative day 6, the patient was extubated without neurologic or cardiac impairment. The patient continues to do well 2 years posttransplant, able to perform independent daily activities of living and his previous job. This case underscores the potential for positive outcomes with profoundly prolonged, effective advanced cardiovascular life support in patients who experience postreperfusion syndrome. PMID:27233818

    Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sickle cell disease clinic at Khartoum Children Emergency Hospital. The study group consisted of 289 patients with sickle cell anaemia, age range from 6 months to 18 years. Data were collected using a questionnaire which include full history, clinical examination findings, chest x-rays, and Electro-cardiography. Tachycardia, systolic murmurs, and cardiomegaly were detected in 28%, 61%, and 54% of patients with SCA respectively. Left ventricular dilatation was observed in 51% of the study group, while right ventricular dilatation was observed in 22% of the patients. Left and right atrial dilatations were observed in 16% and 6% of the patients respectively. Contractility, ejection fraction (EF) were found almost always normal in all study subjects. Chamber dilatations were not associated with any abnormality in Left ventricular functions. Hemglobin (Hb) levels correlated negatively with cardiomegaly. Left Ventricular End Diastolic Dimension (LVEDD) correlates negatively with Hb levels and positively with the severity index. Only four patients (1%) had abnormal valves. In conclusion, cardiac abnormalities in patients with SCA correlate with the age of the patients and the severity of the disease. PMID:27493331

    MRI is an important additional tool in the diagnostic work-up of children with congenital heart disease. This review aims to summarise the role MRI has in this patient population. Echocardiography remains the main diagnostic tool in congenital heart disease. In specific situations, MRI is used for anatomical imaging of congenital heart disease. This includes detailed assessment of intracardiac anatomy with 2-D and 3-D sequences. MRI is particularly useful for assessment of retrosternal structures in the heart and for imaging large vessel anatomy. Functional assessment includes assessment of ventricular function using 2-D cine techniques. Of particular interest in congenital heart disease is assessment of right and single ventricular function. Two-dimensional and newer 3-D techniques to quantify flow in these patients are or will soon become an integral part of quantification of shunt size, valve function and complex flow patterns in large vessels. More advanced uses of MRI include imaging of cardiovascular function during stress and tissue characterisation of the myocardium. Techniques used for this purpose need further validation before they can become part of the daily routine of MRI assessment of congenital heart disease. (orig.)

    Full Text Available Bedside emergency ultrasound has rapidly developed over the past several years and has now become part of the standard of care for several applications. While it has only recently been applied to critically ill pediatric patients, several of the well-established adult indications may be applied to pediatric patients. One of the most important and life-saving applications is bedside echocardiography. While bedside emergency ultrasonography does not serve to replace formal comprehensive studies, it serves as an extension of the physical examination. It is especially useful as a rapid and effective tool in the diagnosis of pericardial effusions, tamponade and in distinguishing potentially reversible causes of pulseless electrical activity from asystole. Most recently, left ventricular function and inferior vena cava measurements have proven helpful in the assessment of undifferentiated hypotension and shock in adults and children. Future research remains to be carried out in determining the efficacy of bedside ultrasonography in pediatric-specific pathology such as congenital heart disease. This article serves as a comprehensive review of the adult literature and a review of the recent applications in the pediatric emergency department. It also highlights the techniques of bedside ultrasonography with examples of normal and pathologic images.

    This qualitative study examined the subjective experience of children undergoing an invasive examination in the hospital when accompanied by a medical clown. In-depth semi-structured interviews were conducted with nine such children and nine of their accompanying parents. The children were patients in two outpatient departments (Pediatric Gastroenterology and a Center for the Sexually Abused) in a hospital in Israel. Interviews were coded thematically using an Atlas.ti software program. Analysis of the interviews indicated that the intervention of the clown positively changed the children's perceptions of the hospital, of experiencing the examination, and of their life narrative. Medical clowns thus appear to be a central, meaningful, and therapeutic source for children undergoing invasive examinations in hospital, as well as for their parents. Therefore, it may be advisable to incorporate medical clowns as an integral part of medical teams performing invasive procedures and to include the clowns in all stages of the hospital visit.

    The close relationship between patent foramen ovale(PFO)and cryptogenic ischemic cerebrovascular disease and migraine has been concerned for years. However,in the field of non-cardiac surgery and anesthesiology, PFO and related clinical problems are less recognized. Under perioperative circumstances,PFO may generate many challenges such as paradoxical systematic embolism and severe hypoxemia. This article briefly introduces the epidemiology, paradoxical embolism, and detection methods of PFO and discribes the perioperative complications and corresponding perioperative strategies for prevention and cure.

    Although single individual reports have documented outcomes in children with pentalogy of are few data available for postoperative outcome of this cohort of patients after cardiac surgery. The aim of this study was to retrospectively review the clinical details of patients with pentalogy of Cantrell managed at two centers. Two cardiac surgical institutions retrospectively studied all patients with pentalogy of Cantrell and significant congenital heart disease who underwent surgical intervention, excluding PDA ligation, between 1992 and 2004. Seven children with pentalogy of Cantrell underwent surgical intervention at a median age of 60 days (range, 1-11 months). Three patients had tetralogy of Fallot, two double outlet right ventricle, one patient had tricuspid atresia, and one patient a perimembranous ventricular septal defect. The mean duration of postoperative ventilation was 112.8 days (range, 4-335 days) but three patients required ventilation for more than 100 days. Patients who had a preoperative diaphragmatic plication required a longer duration of ventilation (mean = 186.5 days [range, 100-273 days] compared with mean = 132 days [range, 4-335 days]). Four patients survived, with three patients weaned from ventilation. Three patients had withdrawal of care following failure to wean from ventilation, following multisystem organ failure, and at the request of their parents. In conclusion, the postoperative care of children with pentalogy of Cantrell after cardiac surgery is often complicated by prolonged need for ventilatory support and multiple postoperative complications. Earlier surgical intervention does not necessarily reduce morbidity and mortality. These data may help in the counseling of parents prior to surgical intervention.

    This study examined the association between patient-reported anxiety and post-cardiac surgery mortality and major morbidity. Frailty ABC'S was a prospective multicenter cohort study of elderly patients undergoing cardiac surgery (coronary artery bypass surgery and/or valve repair or replacement) at 4 tertiary care hospitals between 2008 and 2009. Patients were evaluated a mean of 2 days preoperatively with the Hospital Anxiety and Depression Scale (HADS), a validated questionnaire assessing depression and anxiety in hospitalized patients. The primary predictor variable was high levels of anxiety, defined by HADS score ≥11. The main outcome measure was all-cause mortality or major morbidity (stroke, renal failure, prolonged ventilation, deep sternal wound infection, or reoperation) occurring during the index hospitalization. Multivariable logistic regression examined the association between high preoperative anxiety and all-cause mortality/major morbidity, adjusting for Society of Thoracic Surgeons (STS) predicted risk, age, gender, and depression symptoms. A total of 148 patients (mean age 75.8 ± 4.4 years; 34% women) completed the HADS-A. High levels of preoperative anxiety were present in 7% of patients. There were no differences in type of surgery and STS predicted risk across preoperative levels of anxiety. After adjusting for Society of Thoracic Surgeons predicted risk, age, gender, and symptoms of depression, preoperative anxiety remained independently predictive of postoperative mortality or major morbidity (OR 5.1; 95% CI 1.3, 20.2; p=0.02). In conclusion, although high levels of anxiety were present in a minority of patients anticipating cardiac surgery, this conferred a strong and independent heightened risk of mortality or major morbidity.

  8. Thyroid dose in children undergoing prophylactic cranial irradiation

    International Nuclear Information System (INIS)

    Purpose: To determine the radiation dose received by the thyroid gland as a result of prophylactic cranial irradiation (PCI) in childhood leukemia and the factors influencing that dose. Methods and Materials: The dose to the thyroid resulting from simulated cranial irradiation with parallel opposed lateral fields of an adult anthropomorphic (ART) phantom with both 6 MV X-rays and Cobalt-60 γ-rays was measured using thermoluminescent dosimeters (TLDs). The dependence of thyroid dose on the distance of the field from the thyroid and the proportions of thyroid dose from stray radiation (leakage, scatter from jaws, etc.) and tissue scattered radiation were measured. The effects of a shadow tray and shielding blocks were also determined. Calculation of thyroid dose using the Clarkson scatter integration method was performed for 6 MV X-rays to compare with the measured doses. In vivo thyroid dose estimates were made using TLD measurements for three children receiving PCI with 6 MV X-rays. Results: Using open, unshielded fields, the thyroid region of the phantom received 1.2-1.4% of the prescribed cranial dose for 6 MV X-rays and 1.5-1.7% for Cobalt-60. For both treatment units, stray radiation accounted for approximately two thirds of the thyroid dose and tissue scatter accounted for the remaining one third. The thyroid dose increased as the field moved closer to the thyroid, with an increasing proportion of the dose due to tissue scatter. Placement of a thyroid shielding block on a shadow tray reduced the thyroid dose by only 20% compared with the open, unshielded setup. Thyroid dose from 6 MV using open fields was affected by the orientation of the collimator. When the inferior field edge was defined by the lower jaw, the dose was reduced by 27% compared with the upper jaw. Good correlation of dose to the thyroid region was obtained between phantom measured doses, in vivo measured doses and calculation of dose using the Clarkson method. Conclusion: For PCI doses of

    INTRODUCTION: It is thought that patients with cardiomyopathy have an increased risk of cardiac arrest on induction of anesthesia, but there is little available data. The purpose of this study was to identify the incidence and potential risk factors for cardiac arrest upon induction of anesthesia in children with cardiomyopathy in our institution. METHODS: A retrospective chart review was performed. Eligible patients included patients admitted between 1998 and 2008 with the International Statistical Classification of Disease code for cardiomyopathy (ICD-9 code 425) who underwent airway intervention for sedation or general anesthesia in the operating room, cardiac diagnostic and interventional unit (CDIU) or intensive care unit. Patients undergoing emergency airway intervention following cardiovascular collapse were excluded. For each patient, we recorded patient demographics, disease severity, anesthesia location, and anesthetic technique. RESULTS: One hundred and twenty-nine patients with cardiomyopathy underwent a total of 236 anesthetic events, and four cardiac arrests were identified. One was related to bradycardia (HR<60), two were attributed to bradycardia in association with severe hypotension (systolic blood pressure<45), and the fourth arrest was related to isolated severe hypotension. Two occurred in the operating suite and two in the CDIU. There was no resulting mortality. One patient progressed to heart transplantation. Multiple combinations of anesthetic drugs were used for induction of anesthesia. CONCLUSION: We performed a review of the last 10 years of anesthesia events in children with cardiomyopathy. We report four cardiac arrests in two patients and 236 anesthetic events (1.7%). To the best of our knowledge, this is the largest review of these patients to date but is limited by its retrospective nature. The low cardiac arrest incidence prevents the identification of risk factors and the development of a cardiac arrest risk predictive clinical

    Full Text Available Abstract Background Preoperative anxiety and physical unfitness have been shown to have adverse effects on recovery from cardiac surgery. This study involving cardiac surgery patients was primarily aimed at assessing the feasibility of delivering physical conditioning and stress reduction programs within the public hospital setting. Secondary aims were to evaluate the effect of these programs on quality of life (QOL, rates of postoperative atrial fibrillation (AF and length of stay (LOS in hospital. Methods Elective patients scheduled for coronary artery bypass graft and/or valve surgery at a public hospital in Melbourne, Australia were enrolled. Patients were randomized to receive either holistic therapy (HT or usual care (UC. HT consisted of a series of light physical exercise sessions together with a mental stress reduction program administered in an outpatient setting for the first two weeks after placement on the waiting list for surgery. A self-administered SF-36 questionnaire was used to measure QOL and hospital records to collect data on LOS and rate of postoperative AF. Results The study population comprised 117 patients of whom 60 received HT and 57 received UC. Both programs were able to be delivered within the hospital setting but ongoing therapy beyond the two week duration of the program was not carried out due to long waiting periods and insufficient resources. HT, as delivered in this study, compared to UC did not result in significant changes in QOL, LOS or AF incidence. Conclusions Preoperative holistic therapy can be delivered in the hospital setting, although two weeks is insufficient to provide benefits beyond usual care on QOL, LOS or postoperative AF. Further research is now required to determine whether a similar program of longer duration, or targeted to high risk patients can provide measurable benefits. Trial registration This trial was conducted as part of a larger study and according to the principles contained in

  11. A dosimetric study during cardiac angiography in young children

    International Nuclear Information System (INIS)

    A dosimetric study was carried out in collaboration with the SCPRI in 30 infants during cardiac catheterization for a congenital cardiopathy. As far as the doctor is concerned, the results show that the dose received by the right hand of the operator is the only one that is relatively high and notably higher than in the adult; the other results are in agreement with those published in the literature. For the manipulator the doses received are practically negligible. This finding does not agree with those of certain publications in the literature and it emphasizes the importance of the working conditions for these personnel. For infants, the gonadal dose is much higher than in the adult and the magnitude of the dose relative to the dose at the place of entry of the incident beam, taking into account the weight of the infant, certaintly represents a long-term risk, in particular, in patients who must undergo repeated examinations

    Claudia Schrimpf

    Full Text Available Precise perioperative risk stratification is important in vascular surgery patients who are at high risk for major adverse cardiovascular events (MACE peri- and postoperatively. In clinical practice, the patient's perioperative risk is predicted by various indicators, e.g. revised cardiac index (RCRI or modifications thereof. Patients suffering from chronic kidney disease (CKD are stratified into a higher risk category. We hypothesized that Copeptin as a novel biomarker for hemodynamic stress could help to improve the prediction of perioperative cardiovascular events in patients undergoing vascular surgery including patients with chronic kidney disease.477 consecutive patients undergoing abdominal aortic, peripheral arterial or carotid surgery from June 2007 to October 2012 were prospectively enrolled. Primary endpoint was 30-day postoperative major adverse cardiovascular events (MACE.41 patients reached the primary endpoint, including 63.4% aortic, 26.8% carotid, and 9.8% peripheral surgeries. Linear regression analysis showed that RCRI (P< .001, pre- (P< .001, postoperative Copeptin (P< .001 and Copeptin level change (P= .001 were associated with perioperative MACE, but CKD remained independently associated with MACE and Copeptin levels. Multivariate regression showed that increased Copeptin levels added risk predictive information to the RCRI (P= .003. Especially in the intermediate RCRI categories was Copeptin significantly associated with the occurrence of MACE. (P< .05 Kruskal Wallis test. Subdivision of the study cohort into CKD stages revealed that preoperative Copeptin was significantly associated with CKD stages (P< .0001 and preoperative Copeptin measurements could not predict MACE in patients with more severe CKD stages.Preoperative Copeptin loses its risk predictive potential for perioperative MACE in patients with chronic kidney disease undergoing vascular surgery.

    Anticoagulation of patients with cardiac tamponade (CT) complicating catheter ablation of atrial fibrillation (AF) is an ongoing problem. The aim of this study was to survey the clinical practice of periprocedural anticoagulation in such patients. This study analyzed the periprocedural anticoagulation of 17 patients with CT complicating AF ablation. Emergent pericardiocentesis was performed once CT was confirmed. The mean drained volume was 410.0 ± 194.1 mL. Protamine sulfate was administered to neutralize heparin (1 mg neutralizes 100 units heparin) in 11 patients with persistent pericardial bleeding and vitamin K1 (10 mg) was given to reverse warfarin in 3 patients with supratherapeutic INR (INR > 2.1). Drainage catheters were removed 12 hours after echocardiography confirmed absence of intrapericardial bleeding and anticoagulation therapy was restored 12 hours after removing the catheter. Fifteen patients took oral warfarin and 10 of them were given subcutaneous injection of LMWH (1 mg/kg, twice daily) as a bridge to resumption of systemic anticoagulation with warfarin. Two patients with a small amount of persistent pericardial effusion were given LMWH on days 5 and 13, and warfarin on days 6 and 24. The dosage of warfarin was adjusted to keep the INR within 2-3 in all patients. After 12 months of follow-up, all patients had no neurological events and no occurrence of delayed CT. The results showed that it was effective and safe to resume anticoagulation therapy 12 hours after removal of the drainage catheter. This may help to prevent thromboembolic events following catheter ablation of AF. PMID:25503659

    AIM: To review gastrointestinal and liver infections in children undergoing antineoplastic chemotherapy. To look at gut microflora features in oncology children. METHODS: We selected studies published after year 2000, excluding trials on transplanted pediatric patients. We searched English language publications in MEDLINE using the keywords: “gastrointestinal infection AND antineoplastic chemotherapy AND children”, “gastrointestinal infection AND oncology AND children”, “liver infection AND antineoplastic chemotherapy AND children”, “liver abscess AND chemotherapy AND child”, “neutropenic enterocolitis AND chemotherapy AND children”, “thyphlitis AND chemotherapy AND children”, “infectious diarrhea AND children AND oncology”, “abdominal pain AND infection AND children AND oncology”, “perianal sepsis AND children AND oncology”, “colonic pseudo-obstruction AND oncology AND child AND chemotherapy”, “microflora AND children AND malignancy”, “microbiota AND children AND malignancy”, “fungal flora AND children AND malignancy”. We also analysed evidence from several articles and book references. RESULTS: Gastrointestinal and liver infections represent a major cause of morbidity and mortality in children undergoing antineoplastic chemotherapy. Antineoplastic drugs cause immunosuppression in addition to direct toxicity, predisposing to infections, although the specific risk is variable according to disease and host features. Common pathogens potentially induce severe diseases whereas opportunistic microorganisms may attack vulnerable hosts. Clinical manifestations can be subtle and not specific. In addition, several conditions are rare and diagnostic process and treatments are not standardized. Diagnosis may be challenging, however early diagnosis is needed for quick and appropriate interventions. Interestingly, the source of infection in those children can be exogenous or endogenous. Indeed, mucosal damage may allow the

Diagnosis of arterial oxygen saturation in patients with congenital heart disease (CHD can be used to assess and manage their effecacy. The purpose of this study was to compare pulse oximetry and cardiac catheterizations in treatment manage of children with congenital heart disease. Methods: In the present cross sectional study, 110 patients with cyanic and non syani heart disease were studied undergoing right and left heart catheterization by pulse oximetry of index finger and simultaneously, oxygen saturation was measured by cardiac catheterization. Data were analyzed with SPSS software by using Pearson correlation and linear regression. Results: A significant correlation was seen between arterial oxygen saturation measured by pulse oximetry and arterial oxygen saturation (p<0.0001 as well as heart rate, electrocardiogram and pulse oximetry (p<0.0001 respectively. Furthermore, the presence of cyanosis (p=0.001, digital clubbing of the fingers ((p=0.001, low oxygen saturation in the superior vena cava and right atrium (p=0.002 can reduce the accuracy of pulse oximetry for detection of arterial oxygen saturation. The mean right atrial pressure can effect on accuracy of pulse oximetry to detect heartbeat (p=0.034. Maximum sensitivity and specificity for detection of pulse oximetry oxygen saturation was 88 % and 88 heart rate per minute. Conclusion: Pulse oximetric is a useful tool for estimating the arterial oxygen saturation and heart rate in children with congenital heart disease (CHD and is a non-invasive method in comparison with cardiac catheterization.

Currently, no methods exist to map visual analog scale (VAS scores to utility values. This study aimed to develop and propose a statistical algorithm for mapping five dimensions of health, measured on VASs, to utility scores in patients suffering from cardiovascular disease. Methods: Patients undergoing coronary artery bypass grafting at Aalborg University Hospital in Denmark were asked to score their health using the five VAS items (mobility, self-care, ability to perform usual activities, pain, and presence of anxiety or depression and the EuroQol 5 Dimensions questionnaire. Regression analysis was used to estimate four mapping models from patients' age, sex, and the self-reported VAS scores. Prediction errors were compared between mapping models and on subsets of the observed utility scores. Agreement between predicted and observed values was assessed using Bland–Altman plots. Results: Random effects generalized least squares (GLS regression yielded the best results when quadratic terms of VAS scores were included. Mapping models fitted using the Tobit model and censored least absolute deviation regression did not appear superior to GLS regression. The mapping models were able to explain approximately 63%–65% of the variation in the observed utility scores. The mean absolute error of predictions increased as the observed utility values decreased. Conclusion: We concluded that it was possible to predict utility scores from VAS scores of the five

    Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disease in the world. The long-term effects of subclinical inflammation in FMF are not well recognized. Some studies have suggested that FMF is associated with cardiac autonomic dysfunction in adult FMF patients. The objective of this study was to investigate the cardiac autonomic functions in pediatric FMF patients by using several autonomic tests. Thirty-five patients with FMF and 35 healthy controls were enrolled in this cross-sectional study. Demographic data, disease-specific data, and orthostatic symptoms were recorded. In all participants, 12-lead electrocardiography (ECG), 24 h ambulatory electrocardiographic monitoring, transthoracic echocardiography, treadmill exercise test, and head upright tilt-table (HUTT) test were performed. The heart rate recovery (HRR) indices of the two groups were similar. Also, chronotropic response was similar in both groups. The time-domain parameters of heart rate variability (HRV) were similar in both groups, except mean RR (p = 0.024). Frequencies of ventricular and supraventricular ectopic stimuli were similar in both groups. There were no statistically significant differences between the groups in average QT and average corrected QT interval length, average QT interval dispersion, and average QT corrected dispersion. There was no significant difference between the two groups regarding the ratio of clinical dysautonomic reactions on HUTT. However, we observed a significantly higher rate of dysautonomic reactions on HUTT in patients with exertional leg pain than that in patients without (p = 0.013). When the fractal dimension of time curves were compared, FMF patients exhibited significantly lower diastolic blood pressure parameters than controls in response to HUTT. Cardiovascular autonomic dysfunction in children with FMF is not prominent. Particularly, patients with exertional leg pain are more prone to have dysautonomic features

Platelet function was assessed by two whole blood impedance aggregometers (ROTEM(®) platelet and Multiplate(®) ), using three different activators (arachidonic acid, adenosine diphosphate and thrombin receptor-activating peptide-6), at three peri-operative time points (before anaesthesia, after aortic declamping and 5-10 min after protamine administration). Platelet function was impaired over the time-course in all assays. Results after protamine administration demonstrated the best correlation with postoperative chest tube drainage. Patients with a chest tube drainage exceeding the 75th percentile of the entire study population, during the first 24 postoperative hours, were characterised to have excessive bleeding. Both devices provided similar predictability for postoperative chest tube drainage and red blood cell transfusion requirements. The latter was associated with the degree of platelet inhibition and the number of pathways inhibited determined respective cut-off values. PMID:26763378

    Full Text Available Background: Exercise and rehabilitation are important methods for decreasing the risk factors of coronary artery disease (CAD. We aimed to evaluate the effect of the cardiac rehabilitation (CR exercise program on the cardiac structure and physiology in patients undergoing percutaneous coronary intervention (PCI.Methods: In this randomized controlled study, 146 patients with CAD were divided equally into two groups: case group (undertaking CR after PCI and control group (without rehabilitation after PCI. All the patients in the case group underwent echocardiography (before and after CR, and echocardiography was performed for the control group simultaneously. The CR exercise program encompassed 24 sessions, twice or three times a week, with each session lasting between 15 and 45 minutes, depending on the individual patient’s tolerance. Left ventricular (LV ejection fraction, LV diastolic function, LV end-systolic and diastolic diameter, and right ventricular (RV end-diastolic diameter were measured in the CR group before and after rehabilitation and compared to those in the control group at the same times.Results: In this study, 146 patients (46 female and 100 male were evaluated: 73 in the rehabilitation group and 73 in the control group. The mean age of the patients in the CR and control groups was 58.05 ± 10.27 and 56.76 ± 10.07 years, respectively. The CR exercise program had useful effects on LV diastolic function after PCI. The distribution of LV diastolic dysfunction after the CR exercise program was changed significantly only in the CR group (p value = 0.043. In the CR group, normal, grade I, grade II, and grade III LV diastolic dysfunction were observed in 20.5%, 69.8%, 6.8%, and 2.7%, respectively. This distribution was changed respectively to 30.1%, 61.6%, 5.4%, and 2.7% following CR, which showed a significant improvement due to CR in LV diastolic function, most prominently in the patients with grade I diastolic dysfunction (p

    Full Text Available Background The role of the autonomic nervous system (ANS in the cardiovascular regulation is of primal importance. Since it has been associated with adverse conditions such as cardiac arrhythmias, sudden death, sleep disorders, hypertension and obesity. Objectives The present study aimed to investigate the impact of recreational football practice on the autonomic cardiac function of male children, as measured by heart rate variability. Patients and Methods Forty-seven male children aged 9 - 12 years were selected according to their engagement with football oriented practice outside school context. The children were divided into a football group (FG; n = 22 and a control group (CG; n = 25. The FG had regular football practices, with 2 weekly training sessions and occasional weekend matches. The CG was not engaged with any physical activity other than complementary school-based physical education classes. Data from physical activity, physical fitness, and heart rate variability measured in time and frequency domains were obtained. Results The anthropometric and body composition characteristics were similar in both groups (P > 0.05. The groups were also similar in time spent daily on moderate-to-vigorous physical activities (FG vs. CG: 114 ± 64 vs. 87 ± 55 minutes; P > 0.05. However, the FG performed better (P < 0.05 in Yo-Yo intermittent endurance test (1394 ± 558 vs. 778 ± 408 m and 15-m sprint test (3.06 ± 0.17 vs. 3.20 ± 0.23 s. Also, the FG presented enhanced autonomic function. Significant differences were detected (P < 0.05 between groups for low frequency normalized units (38.0 ± 15.2 vs. 47.3 ± 14.2 n.u (normalized units, high frequency normalized units (62.1 ± 15.2 vs. 52.8 ± 14.2 n.u., and LF:HF ratio (0.7 ± 0.4 vs. 1.1 ± 0.6 ms2. Conclusions Children engaged with regular football practice presented enhanced physical fitness and autonomic function, by increasing vagal tone at rest.

    Approximately 300 children ages 0 to 18 are diagnosed with cancer in Sweden every year, and 80 to 90 of them undergo radiotherapy treatment. The aim was to describe children's experiences of preparing for and undergoing radiotherapy, and furthermore to describe children's suggestions for improvement. Thirteen children between the ages of 5 and 15 with various cancer diagnoses were interviewed. Data was analyzed using qualitative content analysis. The findings revealed five categories: positive and negative experiences with hospital stays and practical arrangements; age-appropriate information, communication, and guidance to various degrees; struggle with emotions; use of distraction and other suitable coping strategies; and children's suggestions for improvement during radiotherapy. An overarching theme emerged: "It is tough and tiring but it works". Some key areas were: explanatory visits, the need for information and communication, being afraid, discomfort and suffering, the need for media distraction, dealing with emotions, and the need for support. A systematic, family-centered preparation program could possible help families prepare and individualized distraction during radiotherapy could contribute to reducing distress. Further studies with interventions could clarify successful programs. PMID:27055258

    AIM: Children who are uncooperative, due either to their age or medical condition, usually require sedation or a general anaesthetic (GA) to ensure immobility during magnetic resonance imaging (MRI) examination. These procedures have a risk of respiratory compromise and loss of vital reflexes. Melatonin induces a natural sleep with no known complication or risk of respiratory compromise. We aimed to evaluate the use of melatonin in these uncooperative children. MATERIAL AND METHODS: An unselected group of 40 children, who had been referred for an MRI examination of the brain under sedation or GA, were chosen to receive melatonin instead. They all received 10 mg of melatonin and 17 children additionally underwent some form of sleep deprivation. The number of children who went to sleep and had a successful MRI examination was recorded. RESULTS: Twenty-six children (65%) went to sleep and of these 22 (55%) had a successful MRI examination. In the 17 children who underwent sleep deprivation, 13 (76%) went to sleep and had a successful MRI examination. There was no complication. CONCLUSIONS: Melatonin may provide an alternative to conventional sedation regimes and GA for uncooperative children undergoing an MRI examination. The use of sleep deprivation improves the success rate and there is no risk of respiratory compromise. Johnson, K. et al. (2002)

    Full Text Available Remote ischemic preconditioning (RIPC has been applied in paediatric cardiac surgery. We have demonstrated that RIPC induces a proteomic response in plasma of healthy volunteers. We tested the hypothesis that RIPC modifies the proteomic response in children undergoing Tetralogy of Fallot (TOF repair.Children (n=40 were randomized to RIPC and control groups. Blood was sampled at baseline, after cardiopulmonary bypass (CPB and 6, 12 and 24h post-CPB. Plasma was analysed by liquid chromatography mass spectrometry (LC-MS in an untargeted approach. Peptides demonstrating differential expression (p<0.01 were subjected to tandem LC-MS/MS and protein identification. Corresponding proteins were identified using the NCBI protein database. There was no difference in age (7.3±3.5vs6.8±3.6 months(p=0.89, weight (7.7±1.8vs7.5±1.9 kg(p=0.71, CPB time (104±7vs94±7 min(p=0.98 or aortic cross-clamp time (83±22vs75±20 min(p=0.36. No peptides were differentially expressed at baseline or immediately after CPB. There were 48 peptides with higher expression in the RIPC group 6h post-CPB. This was no longer evident at 12 or 24h, with one peptide down-regulated in the RIPC group. The proteins identified were: inter-alpha globulin inhibitor (42.0±11.8 vs 820.8±181.1, p=0.006, fibrinogen preproprotein (59.3±11.2 vs 1192.6±278.3, p=0.007, complement-C3 precursor (391.2±160.9 vs 5385.1±689.4, p=0.0005, complement C4B (151.5±17.8 vs 4587.8±799.2, p=0.003, apolipoprotein B100 (53.4±8.3 vs 1364.5±278.2, p=0.005 and urinary proteinase inhibitor (358.6±74.9 vs 5758.1±1343.1, p=0.009.

    Full Text Available Background. The aim of this study was to determine the incidence of pre- and postoperative vomiting in children undergoing a Video-Assisted Gastrostomy (VAG operation. Patients and Methods. 180 children underwent a VAG operation and were subdivided into groups based on their underlying diagnosis. An anamnesis with respect to vomiting was taken from each of the children’s parents before the operation. After the VAG operation, all patients were followed prospectively at one and six months after surgery. All complications including vomiting were documented according to a standardized protocol. Results. Vomiting occurred preoperatively in 51 children (28%. One month after surgery the incidence was 43 (24% in the same group of children and six months after it was found in 40 (22%. There was a difference in vomiting frequency both pre- and postoperatively between the children in the groups with different diagnoses included in the study. No difference was noted in pre- and postoperative vomiting frequency within each specific diagnosis group. Conclusion. The preoperative vomiting symptoms persisted after the VAG operation. Neurologically impaired children had a higher incidence of vomiting than patients with other diagnoses, a well-known fact, probably due to their underlying diagnosis and not the VAG operation. This information is useful in preoperative counselling.

    Full Text Available BACKGROUND: We compared the effects of oral midazolam, butorphanol and clonidine on preoperative sedation and anxiolysis and postoperative recovery profile of the children undergoing elective surgery. MATERIAL AND METHODS : 105 children of either sex, aged between 2 - 6 years, of ASA grade I scheduled for elective surgery were randomized into three groups. Group I: 35 children received midazolam 0.5 mg/kg body weight orally, Group II: 35 children received butorphanol 0.2 mg/kg orally, Group III: 35 children received cloni dine 4 μ/kg orally. Premedication was given 30 minutes before induction of anaesthesia. Children were assessed for attitude to venepuncture and face mask acceptance during induction of anaesthesia. RESULTS: The groups were statistically comparable (p>0.05 , regarding the patients’ demographic profile, hemodynamic variables, duration of surgery and awakening. Less time was required for the onset and time of maximum sedation in midazolam group. Sedation scores were highest in the clonidine group at the time o f induction (p0.05 and minimal with butorphanol. Reaction to i.v cannulation was minimal with clonidine whi le it was comparable in midazolam and butorphanol group. CONCLUSION: clonidine causes the best sedation among the three drugs and it causes minimum response to i.v cannulation and comparable mask acceptance with midazolam followed by butorphanol.

    Children with sickle cell disease (SCD) often undergo MRI studies to assess brain injury or to quantify hepatic iron. MRI requires the child to lie motionless for 30-60 min, thus sedation/anesthesia might be used to facilitate successful completion of exams, but this poses additional risks for SCD patients. To improve children's ability to cope with MRI examinations and avoid sedation, our institution established preparation and support procedures (PSP). To investigate the impact of PSP in reducing the need for sedation during MRI exams among children with SCD. Data on successful completion of MRI testing were compared among 5- to 12-year-olds who underwent brain MRI or liver R2*MRI with or without receiving PSP. Seventy-one children with SCD (median age 9.85 years, range 5.57-12.99 years) underwent a brain MRI (n = 60) or liver R2*MRI (n = 11).

    BACKGROUND Conotruncal heart defects comprise 25%-30% of non-syndromic congenital heart defects. This study describes the frequency of chromosome abnormalities and microdeletion 22q11 associated with conotruncal heart malformations. METHODS From a population base of 974,579 infants/fetuses delivered, 622 Californian infants/fetuses were ascertained with a defect of aortico-pulmonary septation. Infants whose primary cardiac defect was tetralogy of Fallot (n=296) or D-transposition of the great vessels (n=189) were screened for microdeletions of 22q11. RESULTS Fourteen (2.3%) of the 622 infants/fetuses had chromosomal abnormalities. Thirty infants, 10% of those whose primary defect was tetralogy of Fallot, had chromosome 22q11 microdeletions. Right aortic arch, abnormal branching patterns of the major arteries arising from the thoracic aorta, and pulmonary artery abnormalities were observed more frequently in these children. CONCLUSIONS We found an unusual number of infants with an extra sex chromosome and a conotruncal defect. Infants with tetralogy of Fallot due to 22q11 microdeletion showed more associated vascular anomalies than infants with tetralogy but no 22q11 microdeletion. Although these associated vascular anomalies provide clues as to which infants with tetralogy of Fallot are more likely to carry the microdeletion, the overall risk of 10% among all infants with tetralogy of Fallot warrants chromosome analysis and FISH testing routinely.

    Objective: To assess frequency of cardiac defects among children from birth to 12 years of age on each Methodology: A cross sectional study was conducted at echocardiography centre in coronary care unit at Bahawal Victoria Hby Paediatric Transthoracic echo probe; 2-D colour Doppler, Acuson CV-70 and Niemo-30 echocardiography machines. Mothers of children with cardiac defects were interviewed at the echocardiography centre. Variables included were A- Muscular plus Vascular defects; B- Valvular defects; C-Pericardial effusion; D- Dextrocardia and E- Congestive cardiac failure. History of children for sore throat followed by joint pains; history of mothers for drug intake (antihypertensive, antipyretic, anti-emetic, hypoglycaemic) as well as chronic diseases (diabetes mellitus, hypertension, anaemia) during pregnancy were surveyed. Parity of mothers, their cousin marriages, and family socio-economic status was also inquired. The results were tabulated, analyzed and finally subjected to suitable test of significant (SR of proportion) to find out statistical significant if any. Results: It was found that out of 150 patients, 76 (50.66%) were suffering from Cardiac muscular and Vascular defects, 61 (40.66%) Valvular defects, 7 (4.66%) Pericardial effusion, 2 (1.33%) Dextrocardia and 4 (2.66%) from Congestive Cardiac Failure. According to age, 54 (36%) were from birth to 3 years of age and 51 (34%) from 10 to 12 years. There was history of Rheumatic fever among 45 (30%) children. There were 106 (70.6%) children from lower socio-economic class and 79 (52.6%) parents had history of cousin marriages. Conclusion: Frequency of cardiac defects was more in children of male sex, lower socio-economic group, from birth to three years age and children from primipara mothers in our specified locality. Rheumatic fever, cousin's marriage, and prescribed drugs intake during pregnancy (for metabolic and hormonal disorders) were other contributors to cardiac defects. (author)

    Purpose To evaluate if the preoperative administration of levosimendan in patients with right ventricular (RV) dysfunction, pulmonary hypertension, and high perioperative risk would improve cardiac function and would also have a protective effect on renal and neurological functions, assessed using two biomarkers neutrophil gelatinase-associated lipocalin (N-GAL) and neuronal enolase. Methods This is an observational study. Twenty-seven high-risk cardiac patients with RV dysfunction and pulmonary hypertension, scheduled for cardiac valve surgery, were prospectively followed after preoperative administration of levosimendan. Levosimendan was administered preoperatively on the day before surgery. All patients were considered high risk of cardiac and perioperative renal complications. Cardiac function was assessed by echocardiography, renal function by urinary N-GAL levels, and the acute kidney injury scale. Neuronal damage was assessed by neuron-specific enolase levels. Results After surgery, no significant variations were found in mean and SE levels of N-GAL (14.31 [28.34] ng/mL vs 13.41 [38.24] ng/mL), neuron-specific enolase (5.40 [0.41] ng/mL vs 4.32 [0.61] ng/mL), or mean ± SD creatinine (1.06±0.24 mg/dL vs 1.25±0.37 mg/dL at 48 hours). RV dilatation decreased from 4.23±0.7 mm to 3.45±0.6 mm and pulmonary artery pressure from 58±18 mmHg to 42±19 mmHg at 48 hours. Conclusion Preoperative administration of levosimendan has shown a protective role against cardiac, renal, and neurological damage in patients with a high risk of multiple organ dysfunctions undergoing cardiac surgery.

    This study evaluated a virtual tour entitled, "Surgery Virtual Tour," offered on a Web site of a university-affiliated pediatric center. A pre-experimental one-group pretest-posttest design was used to assess the level of health care knowledge, emotional state, degree of utilization, and perceived usefulness of the Virtual Tour. The convenience sample consisted of 138 children having same-day surgery and their parents. The "Surgery Virtual Tour" was used by 55% of 138 families. Children who viewed the Web site had statistically significant higher knowledge scores than those who did not. Although there was no statistically significant difference in emotional distress for children in either group before the surgery (Time 1) to the day of the surgery (Time 2), parents' level of emotional distress increased significantly from Time 1 to Time 2 when they took the Virtual Tour. The results of this study will help clinicians and managers build virtual tours for children undergoing same-day surgery and their parents. PMID:21916345

Children are rarely anesthetized without IV access placement. We performed a retrospective study to determine our incidence of IV access placement during examinations under anesthesia (EUA and the incidence of adverse events that required intraoperative IV access placement.Methods: Data collected from our operating room (OR information system includes but is not limited to diagnosis, anesthesiologist, surgeon, and location of IV catheter (if applicable, patient’s date of birth, actual procedure, and anesthesia/procedure times. We reviewed the OR and anesthetic records of children (>1 month and <10 years who underwent EUAs between January 1, 2003 and May 31, 2009. We determined the percentage of children who were anesthetized without IV access placement, as well as the incidence of any adverse events that required IV access placement, intraoperatively.Results: We analyzed data from 3196 procedures performed during a 77-month period. Patients’ ages ranged from 1 month to 9 years. Overall, 92% of procedures were performed without IV access placement. Procedure duration ranged from 1–39 minutes. Reasons for IV access placement included parental preference for antinausea medication and/or attending preference for IV access placement. No child who underwent anesthesia without an IV line had an intraoperative adverse event requiring insertion of an IV line.Conclusion: Our data suggest that for

    Full Text Available Aim To evaluate the effect of perioperative statin treatment on postoperative atrial fibrillation and cardiac mortality in patients undergoing coronary artery bypass grafting. Methods A total of 1890 patients who underwent isolated coronary artery bypass were analyzed retrospectively, of which 425 patients (22.4% older than 70 were included in the study. The demographic properties, preoperative, operative and postoperative data and other medications of these patients were recorded. Continuous preoperative and postoperative atorvastatin therapy were received by 124 (29.17% patients; 301 (70.82% patients were matched to a control group (no-statin group. The two groups were matched by propensity score analysis in terms of atrial fibrillation development and cardiac mortality. Results Medical history, medical treatment, cardiovascular history, and operative characteristics demonstrated significant heterogeneity in both groups. Postoperative atrial fibrillation was similar in both groups. Before propensity score matching, the percentages of patients in postoperative atrial fibrillation with respect to Atorvastain-group and No-statin-group were 13.71 and 10.3 respectively; however, those were 13.71 and 14.51 after matching. In a multivariate regression analysis, five-vessel bypass (odds ratio OR, 2.354; 95% confidence interval CI, 0.99 to 5.57 was an independent predictor of postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting. In-hospital mortality was higher in the Atorvastatin-group compared with the No-statingroup: 124 (8.9% versus 301 (3.7%, respectively; p=0.027. Conclusion Perioperative atorvastatin treatment is not found to be associated with reduced postoperative atrial fibrillation and cardiac mortality in patients undergoing isolated coronary artery bypass grafting above the age of seventy years.

    Full Text Available AIM: Aim of our study to compare the spinal anaesthesia and general anaesthesia in children undergoing surgeries below umbilicus. OBJECTIVE: to assess the patient comfort in pt. with GA and pt. with spinal anaesthesia, the adequate surgical condition, assess the hemodynamic change, assess the post op analgesia and to assess the post op complication. MATERIAL AND METHOD: 60 ASA grade I & II children of either sex, aged 5-12 yrs undergoing elective surgeries for the lower abdominal, perineal and lower limb surgeries were taken. After taking a detailed history, thorough general physical examination, all pertinent investigation were carried out to exclude any systemic disease. Patients were classified randomly into 2 groups (30 patients in each group. Group A: General anesthesia was given. Group P: subarachnoid block was given. Intraoperative monitoring consisted of SPO2, PR, NIBP, RR and assessment of duration of post-operative analgesia. P-value <0.05 consider significant. RESULT: Analysis revealed that there were no significant differences between the patients with respect to age, sex, duration and type of surgery In SAB since less general anaesthetic drug including parental opioid are used the risk and postoperative respiratory depression is minimal. The stress response to surgery is also limited and recovery is fast. Postoperatively complications like sore throat, laryngeal irritation, cough etc. was also less associated with it. CONCLUSION pediatric spinal anesthesia is not only a safe alternative to general anesthesia but often the anesthesia technique of choice in many lower abdominal and lower limb surgeries in children. The misconception regarding its safety and flexibility is broken and is now found to be even more cost effective. It is much preferred technique special for common day case surgeries generally performed in the pediatric age group.

    With improving survival rates following HSCT in children, QOL and management of short- and long-term effects need to be considered. Exercise may help mitigate fatigue and declines in fitness and strength. The aims of this study were to assess the feasibility of an inpatient exercise intervention for children undergoing HSCT and observe the changes in physical and psychological health. Fourteen patients were recruited, mean age 10 yr. A 6MWT, isometric upper and lower body strength, balance, fatigue, and QOL were assessed prior to Tx and six wk post-Tx. A supervised exercise program was offered five days per week during the inpatient period and feasibility assessed through uptake rate. The study had 100% program completion and 60% uptake rate of exercise sessions. The mean (± s.d.) weekly activity was 117.5 (± 79.3) minutes. Younger children performed significantly more minutes of exercise than adolescents. At reassessment, strength and fatigue were stabilized while aerobic fitness and balance decreased. QOL revealed a non-statistical trend towards improvement. No exercise-related adverse events were reported. A supervised inpatient exercise program is safe and feasible, with potential physiological and psychosocial benefits. PMID:26518227

    Background Oral mucositis is an adverse effect of chemotherapy. Type of chemotherapy regimen is the most important factor causing mucositis. Oral mucositis is usually associated with transient decrease in saliva production. The goal was to study effects of gum consumption on oral mucositis in children undergoing chemotherapy. Materials and Method This randomized controlled trial was done in Amir Kabir Hospital, Arak, Iran. 130 children 5 to 15 years of age were studied. Control group was composed of 65 children who received mucotoxic drugs. Test group was made up of 65 patients received similar drugs in addition to sugar free gums. Patients consumed 6 pieces of gums per day for 15 days. A standardized follow up form and World Health Organization (WHO) grading system for oral mucositis were used for evaluation of patients during 15 days of treatment. Results Severe oral mucositis occurred in 30 (46%) of 65 patients in the test group and in 26 of 65 (40%) patients in the control group. Difference was not statistically significant (P > 0.05). Rate of mild to moderate mucoitis (grade 1 and 2) was significantly lower in patients who used gums (15 % vs. 35%, P < 0.05). Conclusion Our study showed that stimulation of saliva flow by chewing gum could decrease mild to moderate inflammatory injuries of the oral mucosa during chemotherapy. However, it was not effective to subside severe mucositis.

    It is documented that exercise can increase serum cardiac troponins in adults and adolescents; however, there is a lack of related studies concerning the release of cardiac troponins in children. This study investigated the influence of table tennis training on cardiac biomarkers in children. Twenty-eight male children performed six 10-min forehand exercise sessions with 5-min recovery intervals. Serum cardiac troponin T (cTnT) and I (cTnI), and creatinine kinase isoenzyme MB (CK-MB) were assessed before exercise, immediately after the last 10 min of exercise (PEI), 4 h post-exercise (PE4), 24 h post-exercise (PE24), and 48 h post-exercise (PE48). Cardiac function was measured using an ultrasound system (GE Vivid7 Dimension) at rest state. Serum cTnT, cTnI, and CK-MB were significantly elevated from the PEI sample point, and returned to baseline at the PE48 sample point in children. Serum cTnT in four (14.29%), nine (32.14%), and two (7.14%) subjects at the PEI, PE4, and PE24 sample points, respectively, exceeded the cutoff for myocardial injury. At the PE4 sample point, cTnT in five subjects (17.86%) exceeded the cutoff for acute myocardial infarction. Serum cTnI in two (14.29%), seven (25%), and two (7.14 %) subjects at the PEI, PE4, and PE24 timepoints, respectively, exceeded the cutoff for myocardial injury. cTnI in two subjects (7.14%) exceeded the cutoff for acute myocardial infarction at the PE4 timepoint in children. Repeated bouts of table tennis forehand training can significantly increase the release of serum cardiac troponins in some children. PMID:24272170

    Full Text Available This study was carried to assess the efficacy of multimodal analgesia using ketorolac and fentanyl, for post-operative pain relief in children undergoing ambulatory eye surgery. Total of 161 children, aged 1 to 5 years, were randomly stratified to three different analgesic regimens: Group A Ketorolac 0.75 mg.kg -1 I.M. , Group B Fentanyl 0.75 µg.kg -1 I.V. and Group C Ketorolac 0.50mg.kg -1 I.M. and Fentanyl 0.50µg.kg -1 I.V. Ketorolac I.M. was given 45 minutes before extubation and fentanyl I.V. was given soon after extubation in the respective groups. Post-operative pain was assessed in a double blinded manner using Children′s Hospital of Eastern Onatario Pain Scale (CHEOPS scoring system and by recording the heart rate at 10, 30 and 60 minutes. If the score was above 8, the child was left with the parents. In case the score did not improve and persisted to be greater than 8, fentanyl 0.50µg.kg -1 I.V. was given as the rescue analgesia. The incidence of nausea, vomiting, sleep disturbances or any other complaints were recorded by a staff nurse 24 hours post operatively. Mean CHEOPS score at 10, 30 and 60 minutes and mean heart rate at 10 and 30 minutes were significantly higher for Group A compared with Group C. Mean pain score emerged significantly higher for Group B compared with Group C at 30 and 60 minutes, (P< 0.01. Rescue analgesia required was significantly higher in Group A compared to Groups B and C, (P< 0.0001. Post-operatively, significant incidence of drowsiness was reported in children in Group B compared to Groups A and C, (P< 0.01. A multimodal approach using both ketorolac and fentanyl at low doses produce effective and safe analgesia in children undergoing ambula-tory eye surgery.

    In contrast to the results of previous studies, recent randomized controlled trials (RCTs) failed to show a benefit of prophylactic aortic counterpulsation in high-risk patients undergoing cardiac surgery. The present analysis aims to redefine the effects of this treatment modality in the light of this new evidence. MEDLINE, EMBASE, CENTRAL/CCTR, Google Scholar and reference lists of relevant articles were searched for full-text articles of RCTs in English or German. Assessments for eligibility, relevance, study validity and data extraction were performed by two reviewers independently using prespecified criteria. The primary outcome was hospital mortality. A total of nine eligible RCTs with 1171 patients were identified: 577 patients were treated preoperatively with intra-aortic balloon pump (IABP) and 594 patients served as controls. The pooled odds ratio (OR) for hospital mortality (22 hospital deaths in the intervention arm, 54 in the control group) was 0.381 (95% CI 0.230-0.629; P control] = 347) also showed a statistically significant improvement in mortality for preoperative IABP implantation (fixed-effects model: OR 0.267, 95% CI 0.129-0.552, P definition of high-risk patients, an adequately powered, prospective RCT is necessary to find a definite answer to the question, if certain groups of patients undergoing cardiac surgery benefit from a prophylactic IABP insertion.

    BACKGROUND: Spinal anesthesia for cesarean delivery may cause severe maternal hypotension and a decrease in cardiac output. Compared to assessment of cardiac output via a pulmonary artery catheter, the FloTrac/Vigileo™ system may offer a less invasive technique. The aim of this study was to evaluate cardiac output and other hemodynamic measurements made using the FloTrac/Vigileo™ system in patients undergoing spinal anesthesia for elective cesarean section. METHODS: A prospective study enrolling 10 healthy pregnant women was performed. Hemodynamic parameters were continuously obtained at 15 main points: admission to surgery (two baseline measurements), after preload, after spinal anesthesia administration and 4 time points thereafter (4, 6, 8 and 10 min after anesthesia), at skin and uterine incision, newborn and placental delivery, oxytocin administration, end of surgery, and recovery from anesthesia. Hemodynamic therapy was guided by mean arterial pressure, and vasopressors were used as appropriate to maintain baseline values. A repeated measures ANOVA was used for data analysis. RESULTS: There was a significant increase in heart rate and a decrease of stroke volume and stroke volume index up to 10 min after spinal anesthesia (P < 0.01). Importantly, stroke volume variation increased immediately after newborn delivery (P < 0.001) and returned to basal values at the end of surgery. Further hemodynamic parameters showed no significant changes over time. DISCUSSION AND CONCLUSIONS: No significant hemodynamic effects, except for heart rate and stroke volume changes, were observed in pregnant women managed with preload and vasopressors when undergoing elective cesarean section and spinal anesthesia.

    Full Text Available Cardiac siderosis from transfused iron remained, despite iron chelation therapy with desferioxamine (DFO, the major cause of death in Thalassemia major. In a retrospective study, we reviewed 67 patients with Thalassemia major and the same number of non-thalassemic children and analyzed factors affecting cardiac involvement. Ejection fraction (EF and shortening fraction (SF of Thalassemic group was lower than that of non-thalassemic and difference was significant (P<0.001. In Thalassemic patients there was inverse relationship between serum ferritin and cardiac OF and SF. Patients with optimal compliance had lower serum ferritin (P<0.001. 16 patients showed some kind of cardiac involvement. Older (P<0.001, had lower SF (P<0.05 and late onset of DFO therapy (P<0.001. We concluded that patients with Thalassemia major, despite iron chelation therapy with DFO, had weaker cardiac performance compared to non-thalassemic children. In these patients cardiac complications occurred in older age group with late onset of DFO treatment. Echocardiographic measurement of SF has prognostic value.

    Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. PMID:26105060

  10. The relationship between cerebral oxygen saturation changes and post operative neurologic complications in patients undergoing cardiac surgery

    International Nuclear Information System (INIS)

    To study the relationship between cerebral oxygen saturation changes and postoperative neurologic complications. Seventy two adult patients with ASA class II, III who were scheduled for elective cardiac surgery, were randomized into three groups: Group I: with CPB (on -pump) Group II: without CPB (off- pump) Group III: valve surgery. Neuropsychological outcome was assessed by the Mini-Mental State Examination (MMSE). Cerebral oxygen saturation was also measured. There was no statistical difference in desaturation of more than 20% among three groups (P=0.113) but it was significant between group I and II (P=0.042). Changes of rSo/sub 2/ in different hours of surgery was significant in group I and group II (P=0.0001 in both) but it was not significant in group III ( P=0.075) . Although cerebral oximetry is a noninvasive and useful method of monitoring during cardiac surgery, it has low accuracy to determine postoperative neurologic complications. (author)

    Full Text Available Background: Several measurement tools have been used for assessment of postoperative pain in pediatric patients. Self-report methods have limitations in younger children and parent, nurse or physician assessment can be used as a surrogate measure. These tools should be tested in different cultures as pain can be influenced by sociocultural factors. The objective was to assess the inter-rater agreement on four different behavioral pain assessment scales in our local population. Materials and Methods: This prospective, descriptive, observational study was conducted in Pakistan. American Society of Anesthesiologists I and II children, 3-7 years of age, undergoing elective surgery were enrolled. Four pain assessment scales were used, Children′s Hospital of Eastern Ontario Pain Scale (CHEOPS, Toddler Preschool Postoperative Pain Scale (TPPPS, objective pain scale (OPS, and Face, Legs, Activity, Cry, Consolability (FLACC. After 15 and 60 min of arrival in the postanesthesia care unit (PACU, each child evaluated his/her postoperative pain by self-reporting and was also independently assessed by the PACU nurse, PACU anesthetist and the parent. The sensitivity and specificity of the responses of the four pain assessment scales were compared to the response of the child. Results: At 15 min, sensitivity and specificity were >60% for doctors and nurses on FLACC, OPS, and CHEOPS scales and for FLACC and CHEOPS scale for the parents. Parents showed poor agreement on OPS and TPPS. At 60 min, sensitivity was poor on the OPS scale by all three observers. Nurses showed a lower specificity on FLACC tool. Parents had poor specificity on CHEOPS and rate of false negatives was high with TPPS. Conclusions: We recommend the use of FLACC scale for assessment by parents, nurses, and doctors in Pakistani children aged between 3 and 7.

    Full Text Available Abstract Objective: To evaluate the influence of pulmonary hypertension in the ultra-fast-track anesthesia technique in adult cardiac surgery. Methods: A retrospective study. They were included 40 patients divided into two groups: GI (without pulmonary hypertension and GII (with pulmonary hypertension. Based on data obtained by transthoracic echocardiography. We considered as the absence of pulmonary hypertension: a pulmonary artery systolic pressure (sPAP 40 mmHg associated with additional echocardiographic signs of PH. It was established as influence of pulmonary hypertension: the impossibility of extubation in the operating room, the increase in the time interval for extubation and reintubation the first 24 hours postoperatively. Univariate and multivariate analyzes were performed when necessary. Considered significant a P value <0.05. Results: The GI was composed of 21 patients and GII for 19. All patients (100% were extubated in the operating room in a medium time interval of 17.58±8.06 min with a median of 18 min in GII and 17 min in GI. PH did not increase the time interval for extubation (P=0.397. It required reintubation of 2 patients in GII (5% of the total, without statistically significant as compared to GI (P=0.488. Conclusion: In this study, pulmonary hypertension did not influence on ultra-fast-track anesthesia in adult cardiac surgery.

  16. Efficacy and safety of deep sedation by non-anesthesiologists for cardiac MRI in children

    International Nuclear Information System (INIS)

    Cardiac MRI has become widespread to characterize cardiac lesions in children. No study has examined the role of deep sedation performed by non-anesthesiologists for this investigation. We hypothesized that deep sedation provided by non-anesthesiologists can be provided with a similar safety and efficacy profile to general anesthesia provided by anesthesiologists. This is a retrospective chart review of children who underwent cardiac MRI over a 5-year period. The following data were collected from the medical records: demographic data, cardiac lesion, American Society of Anesthesiologists (ASA) physical status, sedation type, provider, medications, sedation duration and adverse events or interventions. Image and sedation adequacy were recorded. Of 1,465 studies identified, 1,197 met inclusion criteria; 43 studies (3.6%) used general anesthesia, 506 (42.3%) had deep sedation and eight (0.7%) required anxiolysis only. The remaining 640 studies (53.5%) were performed without sedation. There were two complications in the general anesthesia group (4.7%) versus 17 in the deep sedation group (3.4%). Sedation was considered inadequate in 22 of the 506 deep sedation patients (4.3%). Adequate images were obtained in 95.3% of general anesthesia patients versus 86.6% of deep sedation patients. There was no difference in the incidence of adverse events or cardiac MRI image adequacy for children receiving general anesthesia by anesthesiologists versus deep sedation by non-anesthesiologists. In summary, this study demonstrates that an appropriately trained sedation provider can provide deep sedation for cardiac MRI without the need for general anesthesia in selected cases. (orig.)

    Full Text Available Objective: The purpose of our study was to determine the effect of induced apnea on quality of cardiopulmonary structures during computerized tomographic (CT angiography images in children with congenital heart diseases. Methods: Pediatric patients with congenital heart defects undergoing cardiac CT angiography at our facility in the past 3 years participated in this study. The earlier patients underwent cardiac CT angiography without induced apnea and while, later, apnea was induced in patients, which was followed by electrocardiogram gated cardiac CT angiography. General anesthesia was induced using sleep dose of intravenous propofol. After the initial check CT, on request by the radiologist, apnea was induced by the anesthesiologist by administering 1 mg/kg of intravenous suxamethonium. Soon after apnea ensued, the contrast was injected, and CT angiogram carried out. CT images in the "apnea group" were compared with those in "nonapnea group." After the completion of the procedure, the patients were mask ventilated with 100% oxygen till the spontaneous ventilation was restored. Results: We studied 46 patients, of whom 36 with apnea and yet another 10 without. The quality of the image, visualization of structures such as cardiac wall, outflow tracts, lung field, aortopulmonary shunts, and coronary arteries were analyzed and subjected to statistical analysis (Mann-Whitney U, Fischer′s exact test and Pearson′s Chi-square test. In the induced apnea group, overall image quality was considered excellent in 89% (n = 33 of the studies, while in the "no apnea group," only 30% of studies were excellent. Absent or minimal motion artifacts were seen in a majority of the studies in apnea group (94%. In the nonapnea group, the respiratory and body motion artifacts were severe in 50%, moderate in 30%, and minimal in 20%, but they were significantly lesser in the apnea group. All the studied parameters were statistically significant in the apnea group in

    Full Text Available BACKGROUND: Results from randomized controlled trials (RCT concerning cardiac and renal effect of remote ischemic preconditioning(RIPC in patients with stable coronary artery disease(CAD are inconsistent. The aim of this study was to explore whether RIPC reduce cardiac and renal events after elective percutaneous coronary intervention (PCI. METHODS AND RESULTS: RCTs with data on cardiac or renal effect of RIPC in PCI were searched from Pubmed, EMBase, and Cochrane library (up to July 2014. Meta-regression and subgroup analysis were performed to identify the potential sources of significant heterogeneity(I(2 ≥ 40%. Eleven RCTs enrolling a total of 1713 study subjects with stable CAD were selected. Compared with controls, RIPC significantly reduced perioperative incidence of myocardial infarction (MI [odds ratio(OR = 0.68; 95% CI, 0.51 to 0.91; P = 0.01; I(2 = 41.0%] and contrast-induced acute kidney injury(AKI (OR = 0.61; 95% CI, 0.38 to 0.98; P = 0.04; I(2 = 39.0%. Meta-regression and subgroup analyses confirmed that the major source of heterogeneity for the incidence of MI was male proportion (coefficient  = -0.049; P = 0.047; adjusted R(2 = 0.988; P = 0.02 for subgroup difference. CONCLUSIONS: The present meta-analysis of RCTs suggests that RIPC may offer cardiorenal protection by reducing the incidence of MI and AKI in patients undergoing elective PCI. Moreover, this effect on MI is more pronounced in male subjects. Future high-quality, large-scale clinical trials should focus on the long-term clinical effect of RIPC.

  1. Cardiac diseases as a risk factor for stroke in Saudi children

    International Nuclear Information System (INIS)

    Objective was to ascertain the role of cardiac diseases as a risk factor for stroke in a cohort of Saudi children who were evaluated in a retrospective and prospective study. Children with cardiac diseases were identified from within a cohort of 104 Saudi children who presented with stroke. They were seen as inpatients in the Pediatric Wards or evaluated at the Outpatient Clinics of the Division of Pediatric Neurology (DPN), and the Division of Pediatric Cardiology at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). A comprehensive form for clinical, neuroimaging, neurophysiological and laboratory data retrieval was designed and completed for each patient. Cardiac evaluation included 12-lead ECG and serial echocardiograms. Cardiac catheterization and 24-hour ambulatory ECG (Holter) were conducted on clinical discretion. Cardiac diseases were the underlying risk factor for stroke in 6 (5.8%) of the 104 children (aged one month to 12 years). The patients (4males and 2 females) were evaluated at the DPN at a mean age of 5.3 years (range=1-8 years; median 6.5 years). Onset of stroke was at a mean age of 34 months (range= 4 months - 8 years; median = 30 months). Five patients had stroke in association with congenital heart disease (CHD), whereas the sixth had restrictive cardiomyopathy. The identified CHD consisted of membranous ventricular septal defect in a 5-year-old boy who had moyamoya syndrome and sickle cell b-thalassemia, asymptomatic patent ductus arteriosus (PDA) in a 17-months-old girl, atrioventricular canal defect and PDA in an 8-year-old boy who also had Down syndrome, partial anomalous pulmonary venous drainage in a one-year-old boy. The latter patient developed hemiparesis secondary to a septic embolus, which evolved into brain abscess involving the right fronto-preital region. This was successfully managed surgically

    The heterogeneous presentation and progression of atrial fibrillation (AF) implicate the existence of different pathophysiological processes. Individualized diagnosis and therapy of the arrhythmogenic substrate underlying AF may be required to improve treatment outcomes. Therefore, this single-center study aims to identify the arrhythmogenic areas underlying AF by intra-operative, high-resolution, multi-site epicardial mapping in 600 patients with different heart diseases. Participants are divided into 12 groups according to the underlying heart diseases and presence of prior AF episodes. Mapping is performed with a 192-electrode array for 5-10 s during sinus rhythm and (induced) AF of the entire atrial surface. Local activation times are converted into activation and wave maps from which various electrophysiological parameters are derived. Postoperative cardiac rhythm registrations and a 5-year follow-up will show the incidence of postoperative and persistent AF. This project provides the first step in the development of a tool for individual AF diagnosis and treatment. PMID:26935733

    The improvement in mortality rates for anesthetized children over the past 50 years reflects the many improvements that have been made in pediatric perioperative care. The modern pediatric anesthesiologist is better trained than the predecessors of half a century ago, and has a vastly improved arsenal of monitoring devices and anesthetic agents from which to choose. The modern pediatric perioperative environment is better equipped to meet the unique needs of children. Techniques practiced by surgeons, nurses, radiologists, and pharmacologists help create a far more sophisticated infrastructure than existed 50 years ago. Given these changes, it is not surprising that outcomes for patients have improved. PMID:11892500

    Background Femoral artery thrombosis is one of the most common complications of catheterizations in infants and young children. This study was conducted to investigate the feasibility and effectiveness of thrombolytic therapy for femoral artery thrombosis after left cardiac catheterization in children.Methods Thrombolytic therapy with urokinase was carried out in children with femoral artery thrombosis after left cardiac catheterization. Each patient was given a bolus injection of heparin (100 U/kg). A bolus of urokinase (30 000-100 000 U) was injected intravenously, and then a continuous infusion of 10 000-50 000 U/h was administered. Transcatheter thrombolysis was performed once previous procedures failed.Results Eight patients (aged (3.1±2.3) years (8 months to 7 years), body weight (13.1±4.2) kg (7 to 20 kg)) presented lower limbs ischemia alter left cardiac catheterizations was performed. Seven patients accepted thrombolytic therapy with urokinase. In 5 patients, peripheral intravenous thrombolysis was successful with restoration of a normal pulse. In the other 3 cases, peripheral intravenous thrombolysis failed, followed by successful transcatheter thrombolysis. The average duration of therapy was (7.25±5.31) hours (1-17 hours). The average doses of heparin and urokinase were (1600±723) U (800-3000 U) and (268 571±177 240) U (50 000-500 000 U), respectively. There were no statistically significant differences in partial thromboplastin time before and during urokinase therapy ((40.6±22.3) to (49.9±39.2) seconds). However, the prothrombin time was significantly longer ((12.7±9.58) to (48.1±18.6) seconds, P<0.05). Patency of the target vessel was evaluated in all the patients for 2 weeks and no occlusion recurred.Conclusion Thrombolytic therapy with urokinase is a safe and useful modality in children with femoral artery thrombosis after left cardiac catheterization.

    Full Text Available A comparative assessment of cardiac performance by the data of clinical-instrumental examination of 50 patients aged 5-15 years with persisting form of partially-controlled atopic bronchial asthma in the period between the attacks of the disease was made. Children were divided into two groups depending on presence of concomitant chronic tonsillitis (18 patients or absence of the latter (32 patients. In all cases by the data of spirography in children against chronic tonsillitis in the period between the attacks of the disease there were revealed ventillation disorders in the lungs by obstruction type, this promoted elevation of pressure in the pulmonary artery. Only in this group of patients in 27,8% of cases pulmonary arterial hypertension of moderate severity was revealed. By echocardiography data in children with asthma against chronic tonsillitis reliably more often (р<0,01 there was revealed decrease of contractile function of myocardium of the left cardiac ventricle; this was caused by the presence of metabolic disturbances in the myocardium in the majority of cases (83,3%. These changes were registered on the electrocardiogram in the form of repolarisation changes of the ventricular complex. Presence of concomitant chronic tonsillitis in children with bronchial asthma favored formation of pulmonary hypertension on the one side and worsening of contractile ability of myocardium of the left cardiac ventricle on the other side; this required performing therapeutic-preventive measures for sanation of chronic infectious focus in the nasopharynx to prevent formation of chronic cardiac insufficiency during asthma course.

  8. The deep inspiration breath hold technique using Abches reduces cardiac dose in patients undergoing left-sided breast irradiation

    International Nuclear Information System (INIS)

    We explored whether the deep inspiration breath hold (DIBH) technique using Abches during left-sided breast irradiation was effective for minimizing the amount of radiation to the heart and lung compared to free breathing (FB). Between February and July 2012, a total of 25 patients with left-sided breast cancer underwent two computed tomography scans each with the DIBH using Abches and using FB after breast-conserving surgery. The scans were retrospectively replanned using standardized criteria for the purpose of this study. The DIBH plans for each patient were compared with FB plans using dosimetric parameters. All patients were successfully treated with the DIBH technique using Abches. Significant differences were found between the DIBH and FB plans for mean heart dose (2.52 vs. 4.53 Gy), heart V30 (16.48 vs. 45.13 cm3), V20 (21.35 vs. 54.55 cm3), mean left anterior descending coronary artery (LAD) dose (16.01 vs. 26.26 Gy, all p 3 of the LAD (41.65 vs. 47.27 Gy, p = 0.017). The mean left lung dose (7.53 vs. 8.03 Gy, p = 0.073) and lung V20 (14.63% vs. 15.72%, p 0.060) of DIBH using Abches were not different significantly compared with FB. We report that the use of a DIBH technique using Abches in breathing adapted radiotherapy for left-sided breast cancer is easily feasible in daily practice and significantly reduces the radiation doses to the heart and LAD, therefore potentially reducing cardiac risk.

    Post-surgical chest tube removal (CTR) is associated with a significant pain and discomfort for patients. Current treatment strategies for reducing CTR-associated pain and anxiety are limited and partially efficacious. To determine the effects of cold application, inhalation of lavender essential oil, and their combination on pain and anxiety during CTR was investigated. This randomized controlled open-label trial was conducted with 80 patients in the cardiac surgery intensive care unit who had a chest tube for duration of at least 24 hours after coronary artery bypass grafting (CABG). Patients were randomized (n=20 in each group) to receive cold application, aromatherapy with lavender oil, cold application in combination with lavender oil inhalation, or none of the above interventions (control group). The intensity and quality of pain and anxiety were evaluated using the visual analogue scale, short form and modified-McGill pain questionnaire (SFM-MPQ) and the Spielberger situational anxiety level inventory (STAII) scale, respectively. Patients in all treatment groups had significantly lower pain intensity and anxiety compared with the control group immediately, 5, 10 and 15 min after CTR. There was no statistically significant difference in the SFM-MPQ total scores between the intervention groups. With respect to anxiety score, there was a significantly reduced anxiety level immediately after CTR in the aromatherapy and cold-aromatherapy combination groups versus the cold application group. The present results suggested the efficacy of cold application and aromatherapy with lavender oil in reducing pain and anxiety associated with post-CABG CTR. PMID:27047319

    Full Text Available Abstract Background Landiolol hydrochloride is a new β-adrenergic blocker with a pharmacological profile that suggests it can be administered safely to patients who have sinus tachycardia or tachyarrhythmia and who require heart rate reduction. This study aimed to investigate whether intraoperative administration of landiolol could reduce the incidence of atrial fibrillation (AF after cardiac surgery. Methods Of the 200 consecutive patients whose records could be retrieved between October 2006 and September 2007, we retrospectively reviewed a total of 105 patients who met the inclusion criteria: no previous permanent/persistent AF, no permanent pacemaker, no renal insufficiency requiring dialysis, and no reactive airway disease, etc. Landiolol infusion was started after surgery had commenced, at an infusion rate of 1 μg/kg/min, titrated upward in 3–5 μg/kg/min increments. The patients were divided into 2 groups: those who received intraoperative β-blocker therapy with landiolol (landiolol group and those who did not receive any β-blockers during surgery (control group. An unpaired t test and Fisher’s exact test were used to compare between-group differences in mean values and categorical data, respectively. Results Seventeen of the 105 patients (16.2% developed postoperative atrial fibrillation: 5/57 (8.8% in the landiolol group and 12/48 (25% in the control group. There was a significant difference between the two groups (P=0.03. The incidence of AF after valve surgery and off-pump coronary artery bypass grafting was lower in the landiolol group, although the difference between the groups was not statistically significant. Conclusions Our retrospective review demonstrated a marked reduction of postoperative AF in those who received landiolol intraoperatively. A prospective study of intraoperative landiolol for preventing postoperative atrial fibrillation is warranted.

    Right ventricular (RV) performance is known to have prognostic value in patients with congestive heart failure (CHF). Cardiac resynchronisation therapy (CRT) has been found to enhance left ventricular (LV) energetics and metabolic reserve in patients with heart failure. The interplay between the LV and RV may play an important role in CRT response. The purpose of the study was to investigate RV oxidative metabolism, metabolic reserve and the effects of CRT in patients with CHF and left bundle brach block. In addition, the role of the RV in the response to CRT was evaluated. Ten patients with idiopathic dilated cardiomyopathy who had undergone implantation of a biventricular pacemaker 8{+-}5 months earlier were studied under two conditions: CRT ON and after CRT had been switched OFF for 24 h. Oxidative metabolism was measured using [{sup 11}C]acetate positron emission tomography (K{sub mono}). The measurements were performed at rest and during dobutamine-induced stress (5 {mu}g/kg per minute). LV performance and interventricular mechanical delay (interventricular asynchrony) were measured using echocardiography. CRT had no effect on RV K{sub mono} at rest (ON: 0.052{+-}0.014, OFF: 0.047{+-}0.018, NS). Dobutamine-induced stress increased RV K{sub mono} significantly under both conditions but oxidative metabolism was more enhanced when CRT was ON (0.076{+-}0.026 vs 0.065{+-}0.027, p=0.003). CRT shortened interventricular delay significantly (45{+-}33 vs 19{+-}35 ms, p=0.05). In five patients the response to CRT was striking (32% increase in mean LV stroke volume, range 18-36%), while in the other five patients no response was observed (mean change +2%, range -6% to +4%). RV K{sub mono} and LV stroke volume response to CRT correlated inversely (r=-0.66, p=0.034). None of the other measured parameters, including all LV parameters and electromechanical parameters, were associated with the response to CRT. In responders, RV K{sub mono} with CRT OFF was significantly lower

    Full Text Available Objective: this study aimed to determine the incidence of nosocomial infections, the risk factors and the impact of these infections on mortality among patients undergoing to cardiac surgery. Methods: Retrospective cohort study of 2060 consecutive patients from 2006 to 2012 at the Santa Casa de Misericórdia de Marília. Results: 351 nosocomial infections were diagnosed (17%, 227 non-surgical infections and 124 surgical wound infections. Major infections were mediastinitis (2.0%, urinary tract infection (2.8%, pneumonia (2.3%, and bloodstream infection (1.7%. The in-hospital mortality was 6.4%. Independent variables associated with non-surgical infections were age > 60 years (OR 1.59, 95% CI 1.09 to 2.31, ICU stay > 2 days (OR 5, 49, 95% CI 2.98 to 10, 09, mechanical ventilation > 2 days (OR11, 93, 95% CI 6.1 to 23.08, use of urinary catheter > 3 days (OR 4.85 95% CI 2.95 -7.99. Non-surgical nosocomial infections were more frequent in patients with surgical wound infection (32.3% versus 7.2%, OR 6.1, 95% CI 4.03 to 9.24. Independent variables associated with mortality were age greater than 60 years (OR 2.0; 95% CI 1.4 to3.0, use of vasoactive drugs (OR 3.4, 95% CI 1.9 to 6, 0, insulin use (OR 1.8; 95% CI 1.2 to 2.8, surgical reintervention (OR 4.4; 95% CI 2.1 to 9.0 pneumonia (OR 4.3; 95% CI 2.1 to 8.9 and bloodstream infection (OR = 4.7, 95% CI 2.0 to 11.2. Conclusion: Non-surgical hospital infections are common in patients undergoing cardiac surgery; they increase the chance of surgical wound infection and mortality.

  13. Initial experience with intravenous pentobarbital sedation for children undergoing MRI at a tertiary care pediatric hospital: the learning curve

    International Nuclear Information System (INIS)

    Objective. Our purpose is to describe the initial experience with intravenous pentobarbital sedation in children undergoing MRI at a tertiary pediatric hospital to identify errors associated with inexperience. Subjects and methods. The study included the first 100 children sedated with intravenous pentobarbital prior to magnetic resonance examination at a tertiary pediatric hospital. The protocol included a maximum dose of 6 mg/kg administered in three divided doses with the total dose not to exceed 200 mg. Flow sheets documenting vital signs, administered drug doses, and adverse reactions were maintained contemporaneous to sedation. Results. Sedation was successful in 92 children. Of the eight children who failed sedation, three were at least 12 years old and three weighed more than 50 kg. χ2 tests identified significantly greater failure rates in children older than 11 years or weight greater than 50 kg. Two children had prolonged sedation after the maximum suggested dose was exceeded. Conclusions. The success rate was good, but could have been improved by restricting the use of pentobarbital to children less than 12 years of age and weighing less than 50 kg. Radiologists inexperienced with intravenous sedation should strictly observe the maximum suggested dose of pentobarbital to prevent prolonged sedation. (orig.)

    Full Text Available Aim: Previous studies demonstrated l-carnitine decreasing doxorubicin-induced cardiotoxicity. Our objectives were to study carnitine levels and cardiac functions in children treated with doxorubicin and the effect of short-term l-carnitine supplements. Materials and Methods: Serial carnitine levels and cardiac functions were obtained in children with newly diagnosed solid malignancies before doxorubicin, after cumulative doses of ≥150 mg/m 2 and ≥300 mg/m 2 , respectively. Oral l-carnitine 100 mg/kg/day for 3 days were given to the children treated with doxorubicin at cumulative doses of ≥150 mg/m 2 and ≥300 mg/m 2 . Carnitine levels and cardiac functions were also obtained in those children before and after short-term oral l-carnitine at each cumulative dose of doxorubicin. Results: Five children (3 females, median age of 9.1 years (range 1.5-13 years with newly diagnosed solid malignancies were enrolled in the study. Free carnitine (FC tended to decrease while acyl-carnitine (AC increased making AC/FC ratio increased after cumulative dose of ≥150 and ≥300 mg/m 2 but the statistics was not significant. Left ventricular (LV systolic function was not significantly changed. Interestingly, LV global function (LV myocardial performance index was significantly increased after 150 mg/m 2 (median 0.39, 0.27-0.51 and 300 mg/m 2 (median 0.46, 0.27-0.50 when compared to baseline (median 0.28, 0.14-0.48 (P=0.05. Carnitine levels and cardiac functions were not significantly changed after oral l-carnitine supplement at cumulative dose of ≥150 mg/m 2 (n=6 and ≥300 mg/m 2 (n=9. Conclusions: Carnitine levels tended to decrease after doxorubicin treatment. LV global dysfunction was documented early after doxorubicin. However, short-term l-carnitine supplement did not improve cardiac function.

    Full Text Available Introduction: Anaemia is associated with increased post-operative morbidity and mortality. We retrospectively assess the relationship between preoperative anaemia and in-hospital mortality in valvular cardiac surgical population. Materials and Methods: Data from consecutive adult patients who underwent valvular repair/ replacement at our institute from January 2010 to April 2014 were collected from hospital records. Anaemia was defined according to WHO criteria (hemoglobin <13g/dl for males and <12g/dl for females. 1:1 matching was done for anemic and non-anemic patients based on propensity for potentially confounding variables. Logistic regression was used to evaluate the relationship between anaemia and in-hospital mortality. MatchIt package for R software was used for propensity matching and SPSS 16.0.0 was used for statistical analysis. Results: 2449 patients undergoing valvular surgery with or without coronary artery grafting were included. Anaemia was present in 37.1% (33.91% among males & 40.88% among females. Unadjusted OR for mortality was 1.6 in anemic group (95% Confidence Interval [95% CI] - 1.041-2.570; p=0.033. 1:1 matching was done on the basis of propensity score for anaemia (866 pairs. Balancing was confirmed using standardized differences. Anaemia had an OR of 1.8 for mortality (95% CI- 1.042 to 3.094, P=0.035. Hematocrit of < 20 on bypass was associated with higher mortality. Conclusion: Preoperative anaemia is an independent risk factor associated with in-hospital mortality in patients undergoing valvular heart surgery.

    Full Text Available Background and Aims: Rapid recovery is desirable after neurosurgery as it enables early post-operative neurological evaluation and prompt management of complications. Studies have been rare comparing the recovery characteristics in paediatric neurosurgical patients. Hence, this study was carried out to compare the effect of sevoflurane and desflurane anaesthesia on emergence and extubation in children undergoing spinal surgery. Methods: Sixty children, aged 1-12 years, undergoing elective surgery for lumbo-sacral spinal dysraphism were enrolled. Anaesthesia was induced with sevoflurane using a face mask. The children were then randomised to receive either sevoflurane or desflurane with oxygen and nitrous oxide, fentanyl (1 μg/kg/h and rocuronium. The anaesthetic depth was guided by bispectral index (BIS ® monitoring with a target BIS ® between 45 and 55. Perioperative data with regard to demographic profile, haemodynamics, emergence and extubation times, modified Aldrete score (MAS, pain (objective pain score, agitation (Cole′s agitation score, time to first analgesic and complications, thereof, were recorded. Statistical analysis was done using STATA 11.2 (StataCorp., College Station, TX, USA and data are presented as median (range or mean ± standard deviation. Results: The demographic profile, haemodynamics, MAS, pain and agitation scores and time to first analgesic were comparable in between the two groups (P > 0.05. The emergence time was shorter in desflurane group (2.75 [0.85-12] min as compared to sevoflurane (8 [2.5-14] min (P < 0.0001. The extubation time was also shorter in desflurane group (3 [0.8-10] min as compared to the sevoflurane group (5.5 [1.2-14] min (P = 0.0003. Conclusion: Desflurane provided earlier tracheal extubation and emergence as compared to sevoflurane in children undergoing surgery for lumbo-sacral spinal dysraphism.

  20. Presentation of congestive cardiac failure in children with ventricular septal defect

    International Nuclear Information System (INIS)

    Background: While there is much data on cardiac problems of adults, there is a limited statistical data available to evaluate the magnitude of the cardiac problems in children in Pakistan. Many of these children present with recurrent chest infections and congestive cardiac failure (CCF), and are managed by general practitioners. A careful search for underlying cardiac problems and awareness about the presentation of CCF and its magnitude will definitely decrease the morbidity and mortality of these children. The objective of this study was to see the frequency and clinical presentation of CCF in children with Ventricular Septal Defect (VSD). Methods: Forty-nine patients met the preset criteria during the study period of 6 months. A detailed history and physical examination with special emphasis on symptoms and signs was sought and the findings were noted in a questionnaire. Data was analysed using SPSS-11. Frequencies and percentages were calculated for all categorical variables. Results: CCF in VSD was found more in males, with a male to female ratio of 1.45:1. Majority (63.1%) of the patients presented in infancy. The common symptoms at presentation were dyspnoea (98%), cough (83.7%), and feeding difficulty (9.6%). Other important symptoms were fever, fatigue, failure to thrive, sweating and wheezing. The common physical signs in order of frequency were murmur 98%, tachypnoea 91.8%, tachycardia 89.8%, hepatomegaly 89.9% and crackles in chest 85.7%. Other presenting signs were displaced apex beat 57%, oedema 28.6% and chest deformity 20.4%. Regarding the type of VSD, peri membranous was the commonest 61.2% as confirmed by echocardiography. Conclusion: This study was done on a smaller scale in hospitalised children. The exact studies regarding CCF in paediatric patients are scarce. There is a need to design more studies in children with CCF. Early recognition of signs and symptoms of CCF on paediatric patients with VSD and awareness at primary health care level

  1. Evaluation of cardiac functions in children by digital subtraction angiography

    International Nuclear Information System (INIS)

    We performed a left ventricular phase analysis of Kawasaki disease by digital subtraction angiography (DSA). Fifty-seven children with Kawasaki disease (32 with normal coronary angiograms and 25 with multiple coronary aneurysms more than 4 mm in diameter) underwent intravenous DSA. Contrast medium was injected from the inferior vena cava. Left ventricular time-density cure was obtained by first-pass method in the right anterior oblique (RAO) projection. After calculating left ventricular ejection fraction (LVEF), phase analysis was done using a pixel-by-pixel Fourier transform of the time-density curve to assess the wall motion abnormalities of left ventricles (LV) due to coronary lesions. We could evaluate LV functions even under the presence of spontaneous respiration in smaller children, after inducing resting respiration by sedative agents. Normal value of the standard deviation (SD) of LV phase histogram was determined to be under 15 degree. We found a negative correlation between the mean values of LV phase histograms and R-R intervals. However, the SD values did not show any correlations with LV ejection fraction, calculated by area-length method using the same digital angiograms, and with number of pixels forming the ROI of end-diastolic LV. Eight cases (7 with coronary lesions and 1 without aneurysms) showed over 15 SD values. The maximum SD value was 22.5 degree in a patient with bilateral large aneurysms. However, there was no significant difference of the SD values between the two groups. The LVEFs were calculated higher than those reported previously in the literature, and the mean LVEF of the patients with coronary lesions was significantly lower than that without aneurysms. In this study sensitivity and specificity in detecting myocardial ischemia could not be evaluated because of the absence of cases with myocardial infarctions. (author)

  2. Follow-up of children exposed to ionising radiation from cardiac catheterisation: the Coccinelle study

    International Nuclear Information System (INIS)

    Cardiac catheterisation has become an essential tool in the diagnosis and treatment of children with a wide variety of congenital and acquired forms of cardiovascular disease. Despite the clear clinical benefit to the patient, radiation exposure from paediatric cardiac catheterisation procedures (CCPs) may be substantial. Given children's greater sensitivity to radiation and the longer life span during which radiation health effects can develop, an epidemiological cohort study, named Coccinelle or 'Ladybird' (French acronym for 'Cohorte sur le risque de cancer apres cardiologie interventionnelle pediatrique'), is carried out in France to evaluate the risks of leukaemia and solid cancers in this population. A total number of 8000 included children are expected. Individual CCP-related doses will be assessed for each child included in the cohort. For each CCP performed, dosimetric parameters (dose-area product, fluoroscopy time and total number of cine frames) are retrieved retrospectively. Organ doses, especially to the lung, the oesophagus and the thyroid, are calculated with PCXMC software. The cohort will be followed up through linkage with French paediatric cancer registries.

  4. Prevalence of long QT syndrome and other cardiac defects in deaf-mute children

    International Nuclear Information System (INIS)

    Background: Long QT syndrome is considered a fatal disease because of its association with ventricular arrhythmias and sudden cardiac death. Objectives of study were to determine the prevalence of long QT syndrome and other heart diseases, in deaf-mute children. Methods: A Cross-sectional descriptive study was conducted at Cholistan special education centre and Cardiology department, Sheikh Zayed hospital Rahim Yar Khan, Pakistan in September 2006. A total of 104 congenitally deaf-mute children were assessed. Height, weight and blood pressure measured, 12-lead electrocardiogram done and QTc calculated using Bazette's formula. Children with prolonged QTc underwent 24-hour ambulatory ECG recording. All were auscultated following complete protocol. A child with murmur was further evaluated with colour Doppler echocardiography. Audiometry was performed on all the children and the result interpreted according to WHO recommendations. Diagnosis of LQTS was based on Revised Schwartz criteria. Results: Out of 104 children, 62 were male with mean age 11.89 yrs. The average systolic and diastolic BP was 97/67 mmHg. Average height was 126 Cm. All children had moderate to severe bilateral sensorineural hearing loss (40-80 dB). One child had associated Patent Ductus Arteriosis. Fifteen had an innocent murmur. Prevalence of congenital heart disease was found to be 0.1/1000. Four children had QT interval more than 440 mSec, (range 0.46-0.47 mSec.). Both genders were equally affected. Three children had high probability of LQTS and one had intermediate probability. Screening of family of these 4 patients showed prolonged QT interval in the sibling of one patient. Conclusion: Our study highlights the significant prevalence of Jervell Lange-Nielsen Syndrome in Pakistani deaf-mute children, which may be associated to the high level of consanguinity in this region. Awareness of this syndrome among health care providers is needed as timely diagnosis and subsequent treatment may prevent

    Full Text Available Children undergoing magnetic resonance imaging examination frequently experience anxiety and fear before and during the scanning. The aim of the present study was to assess: i whether and to what extent psychological interventions might reduce anxiety and fear levels; ii whether the intervention is related to a decrease in the need for sedation. The interventions consisted of three activities: a clown show, dog interaction and live music. The emotional status (anxiety and fear of the children was evaluated before and after the activities through a rating scale questionnaire. The results showed that the activities had high effectiveness in reducing the level of anxiety and fear and decreased the need for sedation in the experimental group compared to the control group. This approach proved to be a positive patient experience, helping to alleviate children’s anxiety and fear, decreasing the need for sedation, and was cost-effective.

    Full Text Available There is no consensus and a limited evidence base for choice of contrast agents (CA in angiography. This study evaluated the impact of iohexol and iodixanol CA on fibrinolytic factors (tissue plasminogen activator [t-PA] and plasminogen activator inhibitor-1 [PAI-1], as well as platelet-monocyte conjugates in cardiac patients undergoing elective angiography in a double-blind, randomised parallel group study.Patients (men, 50-70 years old; n = 12 were randomised to receive either iohexol (Omnipaque; n = 6 or iodixanol (Visipaque; n = 6 during elective angiography at Raigmore Hospital, Inverness, UK. Arterial and venous blood samples were drawn prior to CA delivery and following angiography. Assessment of platelet-monocyte conjugation, t-PA and PAI-1 antigen and activity was conducted in samples pre- and post-angiography.Plasma t-PA antigen was depressed equally in the study groups after angiography, but there was a greater reduction in PAI-1 antigen in the group receiving iodixanol. These findings corresponded to a substantial reduction in t-PA activity in patients receiving iohexol, with no change in those receiving iodixanol (P = 0.023 between the CA groups. Both CAs caused a reduction in platelet-monocyte conjugation, with no difference between the groups. No adverse events were reported during the trial.Avoiding reduced plasma t-PA activity might be an important consideration in choosing iodixanol over iohexol in patients at risk of thrombosis following angiography.

    Purpose Fatigue is an important problem in children receiving intensive chemotherapy and hematopoietic stem cell transplantation (HSCT). Exercise may be an effective intervention for fatigue. Individualized yoga represents an ideal intervention because it can be tailored according to an individual child's needs. Little is known about how to structure a standardized yoga program for intensivelytreated children. Therefore, this study describes the development of a yoga program and an approach to monitoring sessions suitable for hospitalized children receiving intensive chemotherapy or HSCT. Methods The yoga program was designed to increase mobility in hospitalized children and to provide children with relaxation techniques that could be used independently in a variety of environments. The program was founded on 4 key tenets: safety, adaptability, environmental flexibility, and appeal to children. We also developed quality and consistency assurance procedures. Results A menu format with a fixed structure was selected for the yoga program. Each yoga session contained up to 6 sections: breathing exercises, warmup exercises, yoga poses, balancing poses, cool-down poses, and final relaxation. Yoga instructors selected specific yoga poses for each session from a predetermined list organized by intensity level (low, moderate, or high). Monitoring procedures were developed using videotaping and multirater adjudication. Conclusion We created a standardized yoga program and an approach to monitoring that are now ready for incorporation in clinical trials. Future work should include the adaptation of the program to different pediatric populations and clinical settings. PMID:27146130

    Full Text Available End stage liver disease is often associated with growth retardation in children with congenital and hereditary diseases of hepatobiliary system. The aim was to investigate the serum growth hormone level before and after liver transplantation in 52 children with congenital and hereditary diseases of hepatobiliary system. Data of our research work revealed increased serum level of growth hormone in children with liver cirrhosis (3,32 ± 7,7 ng/ml vs. 1,16 ± 1,46 ng/ml in healthy children, p = 0,01, which correlates with PELD score (r = 0,62, p < 0,001. In a month after liver transplantation growth hormone concentration decreases (p < 0,001 and in a year after transplantation it doesn’t differ from healthy children. There wasn’t revealed any interaction between serum growth hormone level and anthropometric parameters before liver transplantation, but in a year after there was significant correlation between growth hormone concentration and height (r = 0,79, p = 0,01. Investigation of growth hormone level in children with liver cirrhosis and its evolution after liver transplantation is of interest as objective criterion of recovery of physical development regulation and as an additional parameter, which cor- relates with severity of end-stage liver disease.

    We retrospectively reviewed the imaging findings, indications, technique and clinical impact in children who had undergone chest CT while undergoing extra-corporeal membrane oxygenation (ECMO). Radiology and ECMO databases were searched to identify all 19 children who had undergone chest CT (20 scans in total) while on ECMO at our institution between May 2003 and May 2012. We reviewed all CT scans for imaging findings. Chest CT is performed in a minority of children on ECMO (4.5% in our series). Timing of chest CT following commencement of ECMO varied among patient groups but generally it was performed earlier in the neonatal group. Clinically significant imaging findings were found in the majority of chest CT scans. Many scans contained several findings, with most cases demonstrating parenchymal or pleural abnormalities. Case examples illustrate the spectrum of imaging findings, including underlying pathology such as necrotising pneumonia and severe barotrauma, and ECMO-related complications such as tension haemothoraces and cannula migration. The results of chest CT led to a change in patient management in 16 of 19 children (84%). There were no adverse events related to patient transfer. An understanding of scan technique and awareness of potential findings is important for the radiologist to provide prompt and optimal image acquisition and interpretation in appropriate patients.

    Objectives: Triclofos may be a better sedative in view of better palatability and less gastric irritation as compared to chloral hydrate. This study aimed to assess the efficacy of triclofos (a commonly used sedative in India) as a sedative for sleep electroencephalogram (EEG) study in children. Methods: This prospective observational study was carried out in a tertiary care pediatric center. Consecutive children aged 6 months to 5 years referred for sleep EEG evaluation were recruited. Their clinical details were noted in a proforma after an informed consent. After a trial for natural sleep, oral triclofos was administered. Sleep parameters and adverse effects were noted. Results: One-hundred and sixty children were then enrolled. EEG was successfully recorded in 149 (93.1%) children. Median latency of sleep onset was 30 min and median duration of sleep was 90 min. The adverse effects in the following 24 h were mild and included dizziness, irritability, and vomiting. Conclusions: Oral triclofos was found to be an effective sedative for EEG in children with minimal adverse effects.

    Individuals with sleep disordered breathing (SDB) can experience changes in automatic cardiac regulation as a result of frequent sleep fragmentation and disturbance in normal respiration and oxygenation that accompany most apnea/hypopnea events. In adults, these changes are reflected in enhanced sympathetic and reduced parasympathetic activity. In this study, we examined the autonomic cardiac regulation in children with and without SDB, through spectral and detrended fluctuation analysis (DFA) of pulse rate variability (PRV). PRV was measured from pulse-to-pulse intervals (PPIs) of the photoplethysmogram (PPG) recorded from 160 children using the Phone Oximeter(™) in the standard setting of overnight polysomnography. Spectral analysis of PRV showed the cardiac parasympathetic index (high frequency, HF) was lower (p < 0.01) and cardiac sympathetic indices (low frequency, LF and LF/HF ratio) were higher (p < 0.01) during apnea/hypopnea events for more than 95% of children with SDB. DFA showed the short- and long-range fluctuations of heart rate were more strongly correlated in children with SDB compared to children without SDB. These findings confirm that the analysis of the PPG recorded using the Phone Oximeter(™) could be the basis for a new screening tool for assessing PRV in non-clinical environment. PMID:26732019

    A nonpharmacological method can be an alternative or complement to analgesics.The aim of this study was to evaluate if music medicine influences pain and anxiety in children undergoing lumbar punctures. A randomized clinical trial was used in 40 children (aged 7-12 years) with leukemia, followed by interviews in 20 of these participants. The participants were randomly assigned to a music group (n = 20) or control group (n = 20). The primary outcome was pain scores and the secondary was heart rate, blood pressure, respiratory rate, and oxygen saturation measured before, during, and after the procedure. Anxiety scores were measured before and after the procedure. Interviews with open-ended questions were conducted in conjunction with the completed procedures. The results showed lower pain scores and heart and respiratory rates in the music group during and after the lumbar puncture. The anxiety scores were lower in the music group both before and after the procedure. The findings from the interviews confirmed the quantity results through descriptions of a positive experience by the children, including less pain and fear. PMID:20386063

    Full Text Available By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma. Group of comparison included 40 healthy peers. Disorders of central and peripheral hemodynamic in attack period of bronchial asthma in children were accompanied both by systolic and diastolic dysfunction of the left and right heart ventricles, herewith right ventricle was functioning in the mode of hyperdynamic, and left one – in the mode of hypodynamic. Combined systolic-diastolic variant of dysfunction both of right and left ventricles was developing in 58,3% of patients with moderately-severe and in 91,6% of patients with severe bronchial asthma. In the attack period of bronchial asthma in children equal directionality of systolic and diastolic dysfunction of heart ventricles was developing; this was characterized by synchronization of their function. Assessment of functional interaction of the ventricles under conditions of severe asthma attack showed direct and high (r=0,67 correlative interaction between finding of Tei index of the left and right ventricles, which characterize their systolic function; this, under conditions of increased hemodynamic pre-loading testified to compensatory increase of systolic interaction of ventricles. Direct and high (r=0,69 correlative interaction between time indices of isovolumic relaxation of the left and right ventricles, characterizing their diastolic function, testified to compensatory increase of diastolic interaction of ventricles under conditions of increase of hemodynamic post-loading. Imbalance of central and peripheral link of hemodynamic in attack period of bronchial asthma in children testified to development of cardiac insufficiency, which was compensated predominantly at the expense of increase of heart contractions rate.

    Extracorporeal membrane oxygenation (ECMO) has traditionally been and, for the most part, still is being performed using roller pumps. Use of first-generation centrifugal pumps has yielded controversial outcomes, perhaps due to mechanical properties of the same and the ensuing risk of hemolysis and renal morbidity. Latest-generation centrifugal pumps, using magnetic levitation (ML), exhibit mechanical properties which may have overcome limitations of first-generation devices. This retrospective study aimed to assess the safety and efficacy of veno-arterial (V-A) ECMO for cardiac indications in neonates, infants, and children, using standard (SP) and latest-generation ML centrifugal pumps. Between 2002 and 2014, 33 consecutive neonates, infants, and young children were supported using V-A ECMO for cardiac indications. There were 21 males and 12 females, with median age of 29 days (4 days-5 years) and a median body weight of 3.2 kg (1.9-18 kg). Indication for V-A ECMO were acute circulatory collapse in ICU or ward after cardiac repair in 16 (49%) patients, failure to wean after repair of complex congenital heart disease in 9 (27%), fulminant myocarditis in 4 (12%), preoperative sepsis in 2 (6%), and refractory tachy-arrhythmias in 2 (6%). Central cannulation was used in 27 (81%) patients and peripheral in 6. Seven (21%) patients were supported with SP and 26 (79%) with ML centrifugal pumps. Median duration of support was 82 h (range 24-672 h), with 26 (79%) patients weaned from support. Three patients required a second ECMO run but died on support. Seventeen (51%) patients required peritoneal dialysis for acute renal failure. Overall survival to discharge was 39% (13/33 patients). All patients with fulminant myocarditis and with refractory arrhythmias were weaned, and five (83%) survived, whereas no patient supported for sepsis survived. Risk factors for hospital mortality included lower (<2.5 kg) body weight (P = 0.02) and rescue ECMO after cardiac

  1. Assessment of cardiac function by radionuclide angiocardiography in children with cardiomyopathy

    International Nuclear Information System (INIS)

    Radionuclide angiography was performed in four children, each having dilated cardiomyopathy (DCM), hypertrophic nonobstructive cardiomyopathy (HCM), hypertrophic obstructive cardiomyopathy (HOCM), or restrictive cardiomyopathy (RCM), whose ages ranged from 5 to 8 years. The peak to peak time of flow from the right to left ventricle, which was corrected by heart rate, was prolonged in all the patients. Left ventricular ejection fraction was low in the DCM patient, and high in the HOCM patient. In the DCM patient, both peak ejection rate and peak filling rate of the left ventricle were low. Two patients with either DCM or HOCM had the prolongation of percent duration to peak filling rate, as opposed to the RCM patient having short percent duration. In the RCM patient, right ventricular ejection fraction was low, and time-volume curve showed rapid filling during early diastole. Radionuclide angiography is recommended as a noninvasive method of evaluating cardiac functional characteristics for various types of myocardiopathy. (Namekawa, K.)

  4. Emergence from anesthesia in children undergoing ambulatory surgery- a comparison between propofol and sevoflurane using single anesthetic technique

    International Nuclear Information System (INIS)

    Objective: To compare emergence from anesthesia using total intravenous anesthesia (TIVA) with propofol and volatile induction maintenance anesthesia (VIMA) with sevoflurane, in children undergoing ambulatory inguinal herniorrhaphy. Study Design: Randomized, controlled trials. Place and Duration of Study: Shifa Hospital of Pakistan Navy, from 1st Mar 2005 to 28th Feb 2006. Patients and Methods: Eighty children, aged 5-10 years of ASA physical status I or II were divided into two groups of 40 each using random numbers table. Group P received propofol 3mg/kg for induction and 100-400 micro g/kg/min infusion for maintenance of anesthesia, while group S received sevoflurane 8% (inspired concentration) in 100% oxygen for induction and 2-3% in oxygen for maintenance of anesthesia. No sedative premedication was given. Analgesia was provided with caudal block using 0.25% bupivacaine. Speed of emergence from anesthesia was assessed by time to extubation, time to eye opening, and time to crying / stating name. A modified aldrete score system was used to evaluate recovery while Pain/Discomfort scale to assess the quality of emergence from anesthesia. These were recorded by a separate consultant anesthetist blind to the anesthetic technique. Results: Emergence from anesthesia occurred significantly quicker in the S group as compared to P group, as evident by times in minutes (mean +- SD) to extubation: 8.3+-6.9 versus 4.7+-2.6(p=0.017), eye opening: 9.1 +- 5.3 vs. 5.6 +- 2.6 (p=0.043) and crying / state name: 14.7 +-7.2 vs.11.3 +- 4.6(p=0.039). Similarly, more patients in the S group scored maximum points in the modified aldrete score at 10 min: 17 (42.5%) vs.7 (17.5%) (p=0.015), 20 min: 32 (80%) vs.23 (57.5%) (p=0.030). Although, number of patients in the S group compared to P group scoring max points in Pain-discomfort scale at 10 min: 8 (20%) vs4 (10%), p=0.210; 20 min: 6 (15%) vs.2 (5%), p=0.136 and 30 min: 4 (10%) vs. 0, p=0.130 were more, these results were not

  5. Assessment of cardiac sympathetic nerve activity in children with chronic heart failure using quantitative iodine-123 metaiodobenzylguanidine imaging

    International Nuclear Information System (INIS)

    Cardiac sympathetic nerve activity in children with chronic heart failure was examined by quantitative iodine-123 metaiodobenzylguanidine (MIBG) myocardial imaging in 33 patients aged 7.5±6.1 years (range 0-18 years), including 8 with cardiomyopathy, 15 with congenital heart disease, 3 with anthracycrine cardiotoxicity, 3 with myocarditis, 3 with primary pulmonary hypertension and 1 with Pompe's disease. Anterior planar images were obtained 15 min and 3 hr after the injection of iodine-123 MIBG. The cardiac iodine-123 MIBG uptake was assessed as the heart to upper mediastinum uptake activity ratio of the delayed image (H/M) and the cardiac percentage washout rate (%WR). The severity of chronic heart failure was class I (no medication) in 8 patients, class II (no symptom with medication) in 9, class III (symptom even with medication) in 10 and class IV (late cardiac death) in 6. H/M was 2.33±0.22 in chronic heart failure class I, 2.50±0.34 in class II, 1.95±0.61 in class III, and 1.39±0.29 in class IV (p<0.05). %WR was 24.8±12.8% in chronic heart failure class I, 23.3±10.2% in class II, 49.2±24.5% in class III, and 66.3±26.5% in class IV (p<0.05). The low H/M and high %WR were proportionate to the severity of chronic heart failure. Cardiac iodine-123 MIBG showed cardiac adrenergic neuronal dysfunction in children with severe chronic heart failure. Quantitative iodine-123 MIBG myocardial imaging is clinically useful as a predictor of therapeutic outcome and mortality in children with chronic heart failure. (author)

    Full Text Available Abstract Background Grass pollen is a major cause of respiratory allergy worldwide and contain a number of allergens, some of theme (Phl p 1, Phl p 2, Phl p 5, and Phl 6 from Phleum pratense, and their homologous in other grasses are known as major allergens. The administration of grass pollen extracts by immunotherapy generally induces an initial rise in specific immunoglobulin E (sIgE production followed by a progressive decline during the treatment. Some studies reported that immunotherapy is able to induce a de novo sensitisation to allergen component previously unrecognized. Methods We investigated in 30 children (19 males and 11 females, mean age 11.3 years, 19 treated with sublingual immunotherapy (SLIT by a 5-grass extract and 11 untreated, the sIgE and sIgG4 response to the different allergen components. Results Significant increases (p  Conclusions These findings confirm that the initial phase of SLIT with a grass pollen extract enhances the sIgE synthesis and show that the sIgE response concerns the same allergen components which induce IgE reactivity during natural exposure.

    Full Text Available This study was aimed to describe the endoscopic picture and laboratory findings in children with chronic abdominal pain and to determine the utility of nodular gastritis in diagnosing HPI in these patients. This prospective study was done between November, 2004 and May, 2007. A total of 70 patients (36 male and 34 female aged 3-14 years, underwent upper endoscopy. H-pylori infection was diagnosed when both urease test and histology were positive for the infection. Seventy percent (n = 49 of them were diagnosed to have endoscopic nodular gastritis. HPI was confirmed in 33 (47.1% of 70 patients. The endoscopic antral nodularity had a sensitivity of 100%, specificity of 56.8%, positive predictive value of 67.3%, negative predictive value of 100% and a positive LR of 2.32 for diagnosis of HPI. It may be recommended that if nodular gastritis observed in a pediatric patient with chronic abdominal pain he/she should be investigated to exclude HPI otherwise no further work up is necessary to confirm HPI.

    Acute kidney injury (AKI) is a well-documented complication of pediatric hematopoietic stem cell transplantation (HSCT). Dialysis after HSCT is associated with a lower overall survival (OS); however, the association between less severe AKI and OS is unclear. We retrospectively studied 205 consecutive pediatric HSCT patients to determine the incidence and impact of all stages of AKI on OS in pediatric HSCT recipients. We used the peak pRIFLE grade during the first 100 days to classify AKI (ie, R = risk, I = injury, F = failure, L = loss of function, E = end-stage renal disease) and used the modified Schwartz formula to estimate glomerular filtration rate. AKI was observed in 173 of 205 patients (84%). The 1-year OS rate decreased significantly with an increasing severity of pRIFLE grades (P OS between patients without AKI and the R/I group. Regardless of the dialysis status, stages F/L/E had significantly lower rates of OS compared with patients without AKI or R/I (P OS among patients with dialysis and F/L/E without dialysis (P = .65). Stages F/L/E predicted mortality independent of acute graft-versus-host disease, gender, and malignancy. The OS of children after HSCT decreases significantly with an increasing severity of AKI within the first 100 days post-transplant. Although our data did not show an increased risk of mortality with stages R/I, stages F/L/E predicted mortality regardless of dialysis. Prevention and minimization of AKI may improve survival after pediatric HSCT. PMID:27034153

    Recent improvements in toxicity profiles of pediatric oncology patients are attributable, in part, to advances in the field of radiation oncology such as intensity modulated radiation (IMRT) and proton therapy (IMPT). While IMRT and IMPT deliver highly conformal dose to targeted volumes, they commonly demand the addition of 2- or 3-dimensional imaging for precise positioning--a technique known as image guided radiation therapy (IGRT). In this manuscript we address strategies to further minimize exposure risk in children by reducing effective IGRT dose. Portal X rays and cone beam computed tomography (CBCT) are commonly used to verify patient position during IGRT and, because their relative radiation exposure is far less than the radiation absorbed from therapeutic treatment beams, their sometimes significant contribution to cumulative risk can be easily overlooked. Optimizing the conformality of IMRT/IMPT while simultaneously ignoring IGRT dose may result in organs at risk being exposed to a greater proportion of radiation from IGRT than from therapeutic beams. Over a treatment course, cumulative central-axis CBCT effective dose can approach or supersede the amount of radiation absorbed from a single treatment fraction, a theoretical increase of 3% to 5% in mutagenic risk. In select scenarios, this may result in the underprediction of acute and late toxicity risk (such as azoospermia, ovarian dysfunction, or increased lifetime mutagenic risk) in radiation-sensitive organs and patients. Although dependent on variables such as patient age, gender, weight, body habitus, anatomic location, and dose-toxicity thresholds, modifying IGRT use and acquisition parameters such as frequency, imaging modality, beam energy, current, voltage, rotational degree, collimation, field size, reconstruction algorithm, and documentation can reduce exposure, avoid unnecessary toxicity, and achieve doses as low as reasonably achievable, promoting a culture and practice of "gentle IGRT

    The importance and variability of pre-operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre-operative anaemia. Centre-specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (EuroSCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p treatment before cardiac surgery is required; these data will assist in designing such trials.

    Cardiac catheterization is important in the diagnosis and risk stratification of pulmonary hypertensive vascular disease (PHVD) in children. Acute vasoreactivity testing provides key information about management, prognosis, therapeutic strategies, and efficacy. Data obtained at cardiac catheterization continue to play an important role in determining the surgical options for children with congenital heart disease and clinical evidence of increased pulmonary vascular resistance. The Pediatric and Congenital Heart Disease Task Forces of the Pulmonary Vascular Research Institute met to develop a consensus statement regarding indications for, conduct of, acute vasoreactivity testing with, and pitfalls and risks of cardiac catheterization in children with PHVD. This document contains the essentials of those discussions to provide a rationale for the hemodynamic assessment by cardiac catheterization of children with PHVD. PMID:27076908

    Full Text Available High cumulative doses of anthracyclines (300–500 mg/m2 used in the treatment of children with cancer may result in cardiotoxicity, a major long-term adverse effect that limits clinical usefulness of this class of chemotherapeutic agents. We assessed anthracycline-induced cardiotoxicity by measuring Pro-BNP levels and echocardiographic (ECHO findings and investigated potential protective effect of selenium (Se supplementation in a group of pediatric cancer patients. Plasma level of Pro-BNP was measured, and ECHO was performed in 67 patients (45 boys, 22 girls; ages 2–18 years; median age 12 years after they completed anthracycline-containing chemotherapy. Serum Se level was measured in 37 patients. Eleven patients had high Pro-BNP levels and/or cardiac failure with Pro-BNP levels of 10–8,022 pg/mL (median 226.3 pg/mL; laboratory normal level is less than 120 pg/mL. Serum Se levels were low (20–129 mcg/L, median 62 mcg/L in ten of these eleven patients. Eight of 10 patients with low Se and high Pro-BNP levels were supplemented with Se 100 mcg/day for a period of 4–33 months (median 6 months which resulted in improvement in Pro-BNP and/or ECHO findings. These results suggest that Se supplementation may have a role in protection against anthracycline-induced cardiac toxicity.

    The use of physical punishment for children is associated with poor psychological and behavioral outcomes, but the causal pathway is controversial, and the effects on later physical health unknown. We conducted a cross-sectional survey of asthma, cancer, and cardiac patients (150 in each category, 75 male) recruited from outpatient clinics and 250 healthy controls (125 male). All participants were 40-60 years old and citizens of Saudi Arabia, where the use of beating and insults is an acceptable parenting style. Demographic data and recalled frequency of beatings and insults as a child were assessed on an 8-point scale. Beating and insults were highly correlated (ρ = 0.846). Propensity score matching was used to control for demographic differences between the disease and healthy groups. After controlling for differences, more frequent beating (once or more per month) and insults were associated with a significantly increased risk for cancer (RR = 1.7), cardiac disease (RR = 1.3) and asthma (RR = 1.6), with evidence of increased risk for cancer and asthma with beating frequency of once every 6 months or more. Our results show that a threatening parenting style of beating and insults is associated with increased risk for somatic disease, possibly because this form of parenting induces stress. Our findings are consistent with previous research showing that child abuse and other early life stressors adversely affect adult somatic health, but provide evidence that the pathogenic effects occur also with chronic minor stress. A stress-inducing parenting style, even when normative, has long term adverse health consequences. PMID:23054177

    To minimize perloperative cardiac events, we utilize a screening protocol consisting of intravenous dipyridamole thallium-201 myocardial imaging (DPT), with the selective use of coronary angiography based on the presence of reversible defect(s) on DPT test. A retrospective study was performed to determine the prognostic value of this protocol and to identify any clinical parameters predictive of an abnormal DPT test. To accomplish this, a detailed chart analysis of 176 consecutive kidney (n = 89) and kidney-pancreas (n = 87) transplant recipients who had undergone pre-transplant DPT testing was performed. The results of the DPT test were interpreted as normal in 111, fixed defect in 15, and reversible defect(s) in 50 patients. Forty-two of the 50 patients with reversible defect(s) underwent coronary angiography. Twelve of the 27 patients with significant coronary artery disease (CAD, > 50% stenosis in one or more coronary arteries) underwent pre-transplant revascularization and the remaining 15 were treated medically. Cardiac events (documented acute myocardial infarction or sudden cardiac death) within 6 wk of transplant were stratified by the results of this protocol. Also, various clinical parameters were compared between patients with normal and abnormal (fixed and reversible defect) DPT tests. Only one of the 111 (0.9%) transplant recipients with a normal DPT test had a perioperative cardiac event. None of the 15 (0%) patients with a fixed defect and none of the 15 (0%) patients with reversible defect(s), but a nonsignificant (<50% narrowing) coronary angiogram, had a perioperative cardiac event. Three of the 27 (11.1%) patients with reversible defect(s) and significant disease on coronary angiography, who had undergone pre-transplant revascularization of were managed medically, had a perioperative coronary event. Of 14 recipients parameters analyzed, age > 50 yr was the only variable predictive of an abnormal DPT test. (au) 33 refs.

  3. Prophylaxis of mucosal toxicity by oral propantheline and cryotherapy in children with malignancies undergoing myeloablative chemo-radiotherapy

    International Nuclear Information System (INIS)

    Mucosal toxicity is an incapacitating complication of intensive chemo-radiotherapy for children with malignant disorders, and is physically and psychologically distressful. It is therefore important to minimize mucosal toxicity in those patients. In this report, the effects of the combined prophylaxis of oral cooling (cryotherapy) and administration of propantheline, an anticholinergic drug, were studied in patients (aged 2-16 year) with acute leukemias or solid tumors, who underwent myeloablative chemo-radiotherapy and autologous peripheral blood stem cell rescue from 1993 to 1997. Patients were pretreated with the combined prophylaxis (n=12) or single prophylaxis (n=5), or left untreated (n=7). The combined prophylaxis significantly reduced the severe mucositis (combined, 8.3%; single, 20.0%; and untreated, 42.9%) and severe diarrhea (combined, 16.7%; single, 60.0%; and untreated, 57.1%). Moreover, the combined prophylaxis tended to shorten the periods of febrile episodes defined as temperature >38 deg C (combined, 3.8 days; single, 4.6 days; and untreated, 5.6 days). Therefore, the combination of propantheline and oral cryotherapy may be feasible and effective for reduction of mucosal toxicity in patients with malignancy who undergo high-dose chemotherapy.

Methods: A prospective, quasi-experimental study with 24 patients who underwent coronary artery bypass and were randomly assigned to two groups in the Phase II cardiac rehabilitation program: inspiratory muscle training program associated with combined training (aerobic and resistance group (GCR + IMT, n=12 and combined training with respiratory exercises group (GCR, n=12, over a period of 12 weeks, with two sessions per week. Before and after intervention, the following measurements were obtained: maximal inspiratory and expiratory pressures (PImax and PEmax, peak oxygen consumption (peak VO2 and quality of life scores. Data were compared between pre- and post-intervention at baseline and the variation between the pre- and post-phase II cardiac rehabilitation program using the Student's t-test, except the categorical variables, which were compared using the Chi-square test. Values of P<0.05 were considered statistically significant. Results: Compared to GCR, the GCR + IMT group showed larger increments in PImax (P<0.001, PEmax (P<0.001, peak VO2 (P<0.001 and quality of life scores (P<0.001. Conclusion: The present study demonstrated that the addition of inspiratory muscle training, even when applied for a short period, may potentiate the effects of combined aerobic and resistance training, becoming a simple and inexpensive strategy for patients who underwent coronary artery bypass and are in phase II cardiac rehabilitation.

    Children undergoing surgical procedures commonly experience stress and anxiety, exhibit negative behaviors, and complain of postoperative pain. Parents also experience anxiety when their children undergo surgery. Therapeutic play intervention has been used to prepare hospitalized children for invasive medical procedures for decades. However, there has been no systematic review to examine the effectiveness of therapeutic play intervention for improving children's health-related outcomes such as perioperative anxiety and postoperative pain. The aim of this review was to synthesize current empirical evidence on the effectiveness of therapeutic play intervention in reducing perioperative anxiety, negative behaviors, and postoperative pain in children undergoing elective surgery and in reducing their parents' perioperative anxiety. Systematic searches of electronic databases of the Cumulative Index to Nursing and Allied Health Literature, PubMed, ProQuest Dissertations and Theses, Scopus, and Web of Science and screening of the reference lists of included articles from these databases identified studies on the topic. Relevant studies were methodologically assessed and appraised by two independent reviewers using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. Six studies were identified. The outcome measurements were heterogeneous across all six studies. These studies had conflicting outcomes regarding the effectiveness of therapeutic play intervention in children's perioperative anxiety, negative behaviors, and postoperative pain. Two studies showed that the intervention significantly reduced parents' preoperative anxiety. The current empirical evidence on the effectiveness of therapeutic play intervention in children's perioperative anxiety, negative behaviors, and postoperative pain is inconclusive. More studies on the effectiveness of therapeutic play intervention using rigorous designs and involving parents are needed. PMID

    The end-of-life (EOL) experience of children who undergo stem cell transplantation (SCT) may differ from that of other children with cancer. To evaluate perspectives and patterns of EOL care after SCT, we surveyed 141 parents of children who died of cancer (response rate, 64%) and their physicians. Chart review provided additional information. Children for whom SCT was the last cancer therapy (n = 31) were compared with those for whom it was not (n = 110). SCT parents and physicians recognized no realistic chance for cure later than non-SCT peers (both P < .001) and were more likely to have a primary goal of cure at death (parents, P < .001; physicians, P = .02). SCT children were more likely to suffer highly from their last cancer therapy and die in the intensive care unit (both P < .001), with less opportunity for EOL preparation. SCT parents who recognized no realistic chance for cure more than 7 days before death along with the physician were more likely to prepare for EOL, and if their primary goal was to reduce suffering, to achieve this (P < .001). SCT is associated with significant suffering and less opportunity to prepare for EOL. Children and families undergoing SCT may benefit from ongoing discussions regarding prognosis, goals, and opportunities to maximize quality of life. PMID:20228275

    Full Text Available Introduction. Search for harmless and simultaneously effective probiotics, which could be successfully used for treatment and prevention of infectious deseases, is currently important. A. viridans is of particular interest, as it is representative of the normal microflora of human with broad spectrum of antibacterial action. The use of this microorganism has a number of advantages: the absence of side effects on the body; high adhesive abilities; resistance to lysozyme in saliva; the ability of use in patients, sensitized to antibiotics and chemotherapeutic drugs; stimulation effects on the human immune system. Material and methods. The purpose of the study was to investigate the antagonism of A. viridans № 167 and autostrains of aerococcuses, isolated at patients, to conditionally - pathogenic microflora of the nose and oropharynx of children with cardiac patology. At the first stage of the study the microflora of the of the nose and oropharynx of 2 investigated categories was examined – 40 children 4-14 years with cardiac patology and 40 healthy children 4-5 years old. The second stage of work was to study the effect of A. viridans on the explored strains. Results and discussion. A. viridans manifests the antagonism to all studied strains of gram-positive and gram-negative microorganisms, except C. albisans. A. viridans antagonistic activity to staphylococci (10 + 3 mm and streptococci (10 + 2mm is at the approximately same level. It is interesting to compare the antagonism of aerococcuses to clinical isolates of S. pyogenes and similar strains from carriers (healthy children category. Impact of aerococcuses on P. mirabilis strain appeared at the highest level. Autosimbionts of A. viridans, isolated from healthy children, are more antagonistic to CPM strains, isolated from these children, than autostrains of A. viridans, isolated from children with with cardiac patology, and higher than the museum strain of A. viridans № 167 antagonism

    We studied surveillance, incidence and outcome of viral infections in children undergoing allogeneic hematopoietic cell transplantation (HCT) in the main pediatric transplant units in Spain. We prospectively collected data from first year post-HCT in every consecutive allogeneic HCT performed during 3 years (N = 215): first HCT = 188 and second HCT = 27; median age = 6.6 years (0.1-20.7). Most patients had acute leukemia (N = 137) and 135 recipients (63%) were CMV seropositive. A total of 46 patients underwent cord blood transplant, 133 patients underwent HCT from alternative donors (62%) and 101 patients received anti-thymocyte globulin. Observational time was completed in 137 patients, whereas the remaining 78 died after a median survival time of 99 days (3-352). CMV was monitored in all patients; adenovirus (ADV) and human herpesvirus 6 (HHV-6) were monitored in 101 and 33 patients, respectively. We found 145 viral infections in 103 patients: CMV (n = 42), ADV (n = 32), HHV-6 (n = 7), polyomavirus (n = 20), EBV (n = 6), VZV (n=17) and others (n = 8). CMV infection was significantly higher in seropositive patients (25 vs 7%) (P = 0.02). Extensive chronic GVHD (cGVHD) was significantly associated with an increased rate of viral infections (12 of 16 patients with cGVHD had infections vs 91 of 199 without GVHD) (P = 0.035). In total, 10 patients (4.6%) died of viral infections (CMV = 5, ADV = 3, respiratory = 2). We found a high incidence of viral infection, but mortality was low. PMID:20228849

Patients and Methods: This prospective, longitudinal study was performed on 300 cardiac surgery patients in a single university hospital. The patients were assessed regarding their preoperative anxiety level using VAS-A, APAIS, and a set of specific anxiety-related questions. Their demographic features as well as their anesthetic and surgical characteristics (ASA physical status, EuroSCORE, preoperative Length of Stay (LoS, and surgical history were recorded, as well. Then, one-way ANOVA and t-test were applied along with odds ratio for risk assessment. Results: According to the results, 94% of the patients presented preoperative anxiety, with 37% developing high anxiety (VAS-A ≥ 7. Preoperative LoS > 2 days was the only significant risk factor for preoperative anxiety (odds ratio = 2.5, CI 95%, 1.3 - 5.1, P = 0.009. Besides, a positive correlation was found between anxiety level (APAISa and requirement of knowledge (APAISk. APAISa and APAISk scores were greater for surgery than for anesthesia. Moreover, the results showed that the most common anxieties resulted from the operation, waiting for surgery, not knowing what is happening, postoperative pain, awareness during anesthesia, and not awakening from anesthesia. Conclusions: APAIS and VAS-A provided a quantitative assessment of anxiety and a specific qualitative questionnaire for preoperative anxiety in cardiac surgery. According to the results, preoperative LoS > 2 days and lack of information related to surgery were the risk factors for high anxiety levels.

    Nosocomial urinary tract infection (UTI) increases hospitalization, cost and morbidity. In this cohort study, we aimed to determine the incidence, risk factors, etiology and outcomes of UTIs in post-operative cardiac children. To this end, we studied all post-operative patients admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in 2012, and we divided the patients into two groups: the UTI (UTI group) and the non-UTI (control group). We compared both groups for multiple peri-operative risk factors. We included 413 children in this study. Of these, 29 (7%) had UTIs after cardiac surgery (UTI group), and 384 (93%) were free from UTIs (control group). All UTI cases were catheter-associated UTIs (CAUTIs). A total of 1578 urinary catheter days were assessed in this study, with a CAUTI density rate of 18 per 1000 catheter days. Multivariate logistic regression analysis demonstrated the following risk factors for CAUTI development: duration of urinary catheter placement (pcongenital abnormalities of kidney and urinary tract (CAKUT) (purinary catheter, the presence of CAKUT, and the presence of syndromes comprised the main risk factors for CAUTI. Gram-negative organisms were the main causes for CAUTI, and one-third of them found to be resistant in this single-center study. PMID:26829892

    Haemophili are pathogenic or opportunistic bacteria often colonizing the upper respiratory tract mucosa. The prevalence of Haemophilus influenzae (with serotypes distribution), and H. parainfluenzae in the nasopharynx and/or the adenoid core in children with recurrent pharyngotonsillitis undergoing adenoidectomy was assessed. Haemophili isolates were investigated for their ability to biofilm production.Nasopharyngeal swabs and the adenoid core were collected from 164 children who underwent adenoidectomy (2-5 years old). Bacteria were identified by the standard methods. Serotyping of H. influenzae was performed using polyclonal and monoclonal antisera. Biofilm formation was detected spectrophotometrically using 96-well microplates and 0.1% crystal violet.Ninety seven percent (159/164) children who underwent adenoidectomy were colonized by Haemophilus spp. The adenoid core was colonized in 99.4% (158/159) children, whereas the nasopharynx in 47.2% (75/159) children (P parainfluenzae and 14 isolates of other Haemophilus spp. were selected. In 20.1% (32/159) children 2 or 3 phenotypically different isolates of the same species (H. influenzae or H. parainfluenzae) or serotypes (H. influenzae) were identified in 1 child. 67.2% (129/192) isolates of H. influenzae, 56.3% (54/96) isolates of H. parainfluenzae and 85.7% (12/14) isolates of other Haemophilus spp. were positive for biofilm production. Statistically significant differences (P = 0.0029) among H. parainfluenzae biofilm producers and nonproducers in the adenoid core and the nasopharynx were detected.H. influenzae and H. parainfluenzae carriage rate was comparatively higher in the adenoid core than that in the nasopharynx in children undergoing adenoidectomy, suggesting that their involvement in chronic adenoiditis. The growth in the biofilm seems to be an important feature of haemophili colonizing the upper respiratory tract responsible for their persistence. PMID:25950686

    Full Text Available Human platelets express Toll-like receptors (TLR 4. However, the mechanism by which TLR4 directly affects platelet aggregation and blood coagulation remains to be explored. Therefore, in this study, we evaluated the platelet TLR4 expression in patients who underwent CABG surgery; we explored the correlation between platelet TLR4 expression and the early outcomes in hospital of patients. Additionally, C57BL/6 and C57BL/6-TlrLPS−/− mice were used to explore the roles of platelet TLR4 in coagulation by platelet aggregometry and rotation thromboelastometry. In conclusion, our results highlight the important roles of TLR4 in blood coagulation and platelet function. Of clinical relevance, we also explored novel roles for platelet TLR4 that are associated with early outcomes in cardiac surgery.

    To assess the incidence of and risk factors for acute adverse drug reactions (ADRs) (occurring within 1 h) following iopromide administration in cardiac catheterization in Chinese 'real-world' practice. Acute ADRs following iopromide administration during coronary angiography or percutaneous coronary intervention (PCI) have not been systematically evaluated in China. TRUST was a prospective, multicenter, observational study conducted at 63 centers in China. Patients received iopromide (300 or 370 mgI/mL) during coronary angiography or PCI (n = 17,513). Acute ADRs occurred in 66 patients (0.38%); ADRs were mild in 58 patients (0.33%) and severe in two patients (0.01%). Most acute ADRs manifested as allergy-like symptoms such as nausea/vomiting [39 patients (0.22%)] and/or rash [15 patients (0.09%)]. The rate of acute ADRs was lower among patients who received premedication (6/3349; 0.18 %) than those who did not (60/14,164; 0.42%; p = 0.0379), and among those who did receive pre-procedural hydration (10/7993; 0.13%) compared with those who did not (56/9520; 0.59%; p contrast media increased the risk of ADRs, while premedication with corticosteroids, pre-procedural hydration and contrast volume Contrast quality was rated as 'Excellent' in 99.1% of patients. The incidence of acute ADRs was very low with iopromide in cardiac catheterization in China. The risk of acute ADRs increased in patients contrast media. Premedication with corticosteroids and pre-procedural hydration may prevent acute ADRs in at-risk patients. PMID:26058857

    íaca con circulación extracorpórea (CEC en niños. MÉTODO: Treinta y dos niños, con edad entre 1 mes y 10 años, citados para cirugía cardíaca con circulación extracorpórea, que fueron distribuidos aleatoriamente en dos grupos: el Grupo MDZ recibió midazolam 0,2 mg.kg-1.h-1, mientras que el Grupo DEX recibió dexmedetomidina 1 µg.kg-1.h-1 durante una hora y enseguida el ritmo de infusión se redujo a la mitad en los dos grupos. Los dos grupos recibieron fentanil 10 µg. kg-1, midazolam 0,2 mg.h-1 y vecuronio 0,2 mg.kg-1 para la inducción de la anestesia. Las mismas dosis de fentanil con vecuronio de la inducción fueron infundidas durante la primera hora después de la inducción y enseguida reducidas a la mitad. Las infusiones fueron iniciadas inmediatamente después de la inducción y mantenidas hasta el final de la cirugía. El isoflurano se administró por un corto tiempo para el control de la respuesta hiperdinámica a la incisión y esternotomía. RESULTADOS: En los dos grupos, la presión arterial sistólica y la frecuencia cardíaca se redujeron ostensiblemente después de una hora de infusión anestésica, pero el aumento de la presión arterial sistólica y diastólica y el de la frecuencia cardíaca al momento de la incisión de la piel, fueron significantemente menores en el Grupo DEX. Un número significativamente menor de pacientes exigió un suplemento con isoflurano en el Grupo DEX. Después de la CEC, los pacientes de los dos grupos tuvieron respuestas hedominámicas similares. CONCLUSIONES: La infusión sin bolo de dexmedetomidina parece ser un adyuvante efectivo del fentanil en la promoción de la sedación y el control de las respuestas hemodinámicas durante la cirugía para las cardiopatías congénitas en niños.BACKGROUND AND OBJECTIVES: To evaluate the efficacy of the combined infusion of dexmedetomidine and fentanyl on the hemodynamic response during cardiac surgery with cardiopulmonary bypass (CPB in children.

    Study of 80 consecutive patients undergoing elective diagnostic cardiac catheterisation showed that after the procedure 25 (31%) developed myoglobinaemia. This was attributed to complications of the catheterisation in two. The remaining 23 had received premedication by intramuscular injection. In patients without intramuscular injections myoglobinaemia did not occur after uncomplicated cardiac catheterisation. The study did not support the proposition that cardiac catheterisation results in m...

    Full Text Available OBJECTIVE - A prospective, nonrandomized clinical study to assess splanchnic perfusion based on intramucosal pH in the postoperative period of cardiac surgery and to check the evolution of patients during hospitalization. METHODS - We studied 10 children, during the immediate postoperative period after elective cardiac surgery. Sequential intramucosal pH measurements were taken, without dobutamine (T0 and with 5mcg/kg/min (T1 and 10 (T2 mcg/kg/min. In the pediatric intensive care unit, intramucosal pH measurements were made on admission and 4, 8, 12, and 24 hours thereafter. RESULTS - The patients had an increase in intramucosal pH values with dobutamine 10mcg/kg/min [7.19± 0.09 (T0, 7.16±0.13(T1, and 7.32±0.16(T2], (p=0.103. During the hospitalization period, the intramucosal pH values were the following: 7.20±0.13 (upon admission, 7.27±0.16 (after 4 hours, 7.26±0.07 (after 8 hours, 7.32±0.12 (after 12 hours, and 7.38±0.08 (after 24 hours, (p=0.045. No deaths occurred, and none of the patients developed multiple organ and systems dysfunction. CONCLUSION - An increase in and normalization of intramucosal pH was observed after dobutamine use. Measurement of intramucosal pH is a type of monitoring that is easy to perform and free of complications in children during the postoperative period of cardiac surgery.

  3. Vascular time-activity variation in patients undergoing 123I-MIBG myocardial scintigraphy: implications for quantification of cardiac and mediastinal uptake

    International Nuclear Information System (INIS)

    For the quantification of cardiac 123I-metaiodobenzylguanidine (MIBG) uptake, the mediastinum is commonly used as a reference region reflecting nonspecific background activity. However, variations in the quantity of vascular structures in the mediastinum and the rate of renal clearance of 123I-MIBG from the blood pool may contribute to increased interindividual variation in uptake. This study examined the relationship between changes in heart (H) and mediastinal (M) counts and the change in vascular 123I-MIBG activity, including the effect of renal function. Fifty-one subjects with ischemic heart disease underwent early (15 min) and late (4 h) anterior planar images of the chest following injection of 123I-MIBG. Vascular 123I-MIBG activity was determined from venous blood samples obtained at 2 min, 15 min, 35 min, and 4 h post-injection. From the vascular clearance curve of each subject, the mean blood counts/min per ml at the time of each acquisition and the slope of the clearance curve were determined. Renal function was expressed as the estimated creatinine clearance (e-CC) and the estimated glomerular filtration rate (e-GFR). Relations between H and M region of interest (ROI) counts/pixel, vascular activity, and renal function were then examined using linear regression. Changes in ROI activity ratios between early and late planar images could not be explained by blood activity, the slope of the vascular clearance curves, or estimates of renal function. At most 3% of the variation in image counts could be explained by changes in vascular activity (p = 0.104). The e-CC and e-GFR could at best explain approximately 1.5% of the variation in the slopes of the vascular clearance curve (p = 0.194). The change in measured H and M counts between early and late planar 123I-MIBG images is unrelated to intravascular levels of the radiopharmaceutical. This suggests that changes in M counts are primarily due to decrease in soft tissue activity and scatter from the adjacent

    Due to the neurotoxicity effects of general anesthesia (GA) and sedatives found in animal studies, there is a general recommendation to avoid nonurgent surgical procedures requiring anesthesia in children younger than 3 years of age. The aim of this study was to determine the incidence of anesthesia-related postoperative cognitive dysfunction (POCD) on the first day (Day 1) and at 6 weeks after elective noncardiac surgery in school-age children.This was a prospective cohort study of 118 children undergoing GA and 126 age-matched controls of school children aged 5 to 12 years. All children were given a panel of 4 neuropsychological assessments (Hong Kong List Learning for verbal memory, Visual Matching for processing speed, Visual Memory, and General Comprehension Skill from the Hong Kong Wechsler Intelligence Scale for Children). The primary outcome was the incidence of POCD on Day 1 and at 6 weeks after surgery. POCD was defined as when at least 2 of the 4 cognitive function tests showed individual Z-scores ≤-1.96 or a combined Z-score ≤-1.96.Using the combined Z-score definition, the incidence of POCD in the GA group on Day 1 and at 6 weeks were 5.1% (95% confidence interval [CI]: 2.1-10.3) and 3.4% (95% CI: 1.1-8.0), respectively. No POCD was found using the other definition. The incidences of decline and improvement in neuropsychological tests were similar between groups over time except for a higher risk in visual matching impairment in the anesthesia group (11.9%) versus control group (1.6%) on Day 1 (P definitions and relative risk ratio methodology, we found no anesthesia-related POCD per se in school-age children.

    Full Text Available Several protective measures have been described to prevent contrast-induced nephropathy (CIN. This study is aimed to evaluate the effect of a high dose of N-acetylcysteine (NAC plus hydration, a low dose of NAC plus ascorbic acid and hydration or hydration alone on the prevention of CIN in high-risk patients undergoing elective coronary artery intervention. We conducted a randomized, prospective, placebo-controlled trial of 105 high-risk patients undergoing elective cardiac catheterization. The patients were divided into three different groups: Group A (n = 30, NAC 1200 mg orally before angiography and 1200 mg orally twice daily for three doses along with good hydration; Group B (n = 30, NAC 600 mg before angiography and 600 mg orally twice daily for three doses plus ascorbic acid (3000 mg one dose before angiography and 2000 mg two doses after angiography and good hydration; and Group C (n = 45, hydration with 0.9% saline started just before contrast media injection and continued for 12 h at a rate 1.0 mL/kg/min after angiography or 0.5 mL/kg/h in cases with overt heart failure for 12 h. CIN was defined as an increase in serum creatinine of >25% of baseline or an absolute increase of 0.5 mg/dL above baseline after 48 h. The incidence of CIN was significantly lower in Group A (6.66% compared with Group B (16.66% or Group C (17.77%. The difference between Groups A and B and between Groups A and C was also highly significant (P = 0.001. In contrast, the difference between Groups B and C was not statistically significant (P = 0.37. Our study indicates that high doses of NAC plus hydration provide better protection against CIN than combination therapy of NAC and ascorbic acid plus hydration, or hydration alone.

    Objective: To investigate the effect of Shen-Fu (SF) injection on gastrointestinal tract injury and its potential mechanism. Methods: Thirty-eight patients undergoing elective open heart surgery were assigned to Group C (control group, n=18) and Group SF (n=20) randomly. In Group SF, the patients received intravenous injection of SF (0.5 ml/kg) at the beginning of the surgery followed by a continuous infusion of 100 ml SF (1.0 ml/kg) solution diluted by saline at a rate of 0.004 ml*Kg-1*min-1with a Grasby pump. The control group was injected with normal saline in the same volume. Gastric intramucosal pH (pHi), activity of blood diamine oxidase (DAO), and concentrations of blood LPS and IL-6 were measured before CPB (S0) and 1 h (S1) and 2 h (S2) after aortic declamping, respectively.Results: In Group C, pHi value was significantly lower at S1 and S2 than at S0 ( mean P<0.01) and blood DAO and concentrations of LPS and IL-6 were significantly higher at S1 and S2 than at S0 ( meanP<0.01). In Group SF, pHi was obviously lower at S1 and S2 than at S0 (P<0.05) but LPS and IL-6 levels and DAO were higher at S0 (mean P<0.05). Blood DAO and LPS level demonstrated significant negative correlations with pHi (mean P<0.01) while LPS concentration showed a positive correlation with blood DAO (P<0.01) and IL-6 concentration(P<0.05). At S1 and S2 after aortic declamping, the levels of pHi were higher in Group SF than in Group C (mean P<0.01 ) but DAO and LPS and IL-6 levels were significantly lower in Group SF than in Group C ( P<0.01).Conclusions: SF has a protective effect on gastrointestinal tract and can reduce inflammatory actions.

    Full Text Available OBJECTIVE: As almost any version of percutaneous nephrolithotomy (PCNL was safely and efficiently applied for adults as well as children without age being a limiting risk factor, the aim of the study was to compare the different characteristics as well as the efficacy, outcome, and safety of the pediatric and adult patients who had undergone mini-PCNL (MPCNL in a single institution. METHODS: We retrospective reviewed 331 renal units in children and 8537 renal units in adults that had undergone MPCNL for upper urinary tract stones between the years of 2000-2012. The safety, efficacy, and outcome were analyzed and compared. RESULTS: The children had a smaller stone size (2.3 vs. 3.1 cm but had smilar stone distribution (number and locations. The children required fewer percutaneous accesses, smaller nephrostomy tract, shorter operative time and less hemoglobin drop. The children also had higher initial stone free rate (SFR (80.4% vs. 78.6% after single session of MPCNL (p0.05. Both groups had low rate of high grade Clavien complications. There was no grade III, IV, V complications and no angiographic embolization required in pediatric group. One important caveat, children who required multiple percutaneous nephrostomy tracts had significant higher transfusion rate than in adults (18.8% vs. 4.5%, p = 0.007. CONCLUSIONS: This contemporary largest-scale analysis confirms that the stone-free rate in pediatric patients is at least as good as in adults without an increase of complication rates. However, multiple percutaneous nephrostomy tracts should be practiced with caution in children.

    Sensorimotor cortex plasticity induced by constraint-induced movement therapy (CIMT) in six children (10.2 ± 2.1 years old) with hemiplegic cerebral palsy (CP) was assessed by functional near-infrared spectroscopy (fNIRS). The activation laterality index and time-to-peak/duration during a finger tapping task were quantified before, immediately after, and six months after CIMT. Five age-matched healthy children (9.8 ± 1.3 years old) were also imaged at the same time points to provide comparative activation metrics for normal controls. In children with CP the activation time-to-peak/duration for all sensorimotor centers displayed significant normalization immediately after CIMT that persisted six months later. In contrast to this longer term improvement in localized activation response, the laterality index that depended on communication between sensorimotor centers improved immediately after CIMT, but relapsed six months later.

    Sudden death in the young is rare. About 25% of cases occur during sports. Most young people with sudden cardiac death (SCD) have underlying heart disease, with hypertrophic cardiomyopathy and coronary artery anomalies being commonest in most series. Arrhythmogenic right ventricular dysplasia and long QT syndrome are the most common primary arrhythmic causes of SCD. It is estimated that early cardiopulmonary resuscitation and widespread availability of automatic external defibrillators could prevent about a quarter of pediatric sudden deaths

  15. Postoperative cardiac arrest due to cardiac surgery complications

    International Nuclear Information System (INIS)

    To examine the role of anesthetists in the management of cardiac arrest occurring in association with cardiac anesthesia. In this retrospective study we studied the potential performances for each of the relevant incidents among 712 patients undergoing cardiac operations at Golestan and Naft Hospitals Ahwaz between November 2006 and July 2008. Out of total 712 patients undergoing cardiac surgery, cardiac arrest occurred in 28 cases (3.9%) due to different postoperative complications. This included massive bleeding (50% of cardiac arrest cases, 1.9% of patients); pulseless supra ventricular tachycardia (28.5% of cardiac arrest cases, 1.1% of patients); Heart Failure (7% of cardiac arrest cases, 0.2% of patients); Aorta Arc Rapture (3.5% of cardiac arrest cases, 0.1% of patients); Tamponade due to pericardial effusion (3.5% of cardiac arrest cases, 0.1% of total patients); Right Atrium Rupture (3.5% of cardiac arrest cases, 0.1% of patients) were detected after cardiac surgery. Out of 28 cases 7 deaths occurred (25% of cardiac arrest cases, 0.1% of patients). The most prevalent reason for cardiac arrest during post operative phase was massive bleeding (50%) followed by pulseless supra ventricular tachycardia (28.5%). Six patients had some morbidity and the remaining 15 patients recovered. There are often multiple contributing factors to a cardiac arrest under cardiac anesthesia, as much a complete systematic assessment of the patient, equipment, and drugs should be completed. We also found that the diagnosis and management of cardiac arrest in association with cardiac anesthesia differs considerably from that encountered elsewhere. (author)

    2015-01-01

    This prospective randomized study with double blind control was designed to evaluate the effectiveness of various anesthetic techniques employed prior to fibroendoscopy of the nose, nasopharynx, and larynx of the children. The study included 160 children at the age varying from 3 to 14 (mean 7.4±2.96) years randomly allocated to four statistically comparable groups matched for age and sex. The following preparations were used to treat the children prior to fibroendoscopy: physiological solution (group 1), a 0.05% xylometazoline solution (group 2), a 10% lidocaine solution (group 3), and a mixture of 0.05% xylometazoline and 10% lidocaine solutions (group 4). The evaluation of the tolerance to the pretreatment of the nasal cavity with lidocaine and lidocaine plus xylometazoline (groups 3 and 4) showed that it was significantly (p0.05). The doctors found the tolerance of fibroendoscopy to be the worst following pretreatment with the physiological solution (group 1) and the best after pretreatment with a mixture of lidocaine and xylometazoline (group 4) (p=0.03). The children comprising groups 2 and 3 were not significantly different in terms of the tolerance to fibroendoscopy (p>0.05). It is concluded that the pretreatment of the nasal cavity of the children with a 10% lidocaine solution before fibroendoscopy has no advantage over the pretreatment with a 0.05% xylometazoline solution; at the same time, insuflation of lidocaine as an anesthetic induces more pronounced negative emotions compared with the application of 0.05% xylometazoline.

    Full Text Available OBJECTIVE: to evaluate changes in the biochemical profile of children treated or being treated for moderate or severe stunting in a nutrition recovery and education center. METHODS: this was a retrospective longitudinal study of 263 children treated at this center between August of 2008 to August of 2011, aged 1 to 6 years, diagnosed with moderate (z-score of height-for-age [HAZ] < -2 or severe stunting (HAZ < -3. Data were collected on socioeconomic conditions, dietary habits, and biochemical changes, as well as height according to age. RESULTS: the nutritional intervention showed an increase in HAZ of children with moderate (0.51 ± 0.4, p = 0.001 and severe (0.91 ± 0.7, p = 0.001 stunting during the monitoring. Increased levels of insulin-like growth factor 1 (IGF-1 (initial: 71.7 ng/dL; final: 90.4 ng/dL; p = 0.01 were also observed, as well as a reduction in triglycerides (TG in both severely (initial: 91.8 mg/dL; final: 79.1 mg/dL; p = 0.01 and in moderately malnourished children (initial: 109.2 mg/dL; final 88.7 mg/dL; p = 0.01, and a significant increase in high-density lipoprotein cholesterol HDL-C only in the third year of intervention (initial: 31.4 mg/dL; final: 42.2 mg/dL. The values of total cholesterol (TC and low-density lipoprotein cholesterol (LDL-C levels remained high throughout the treatment (initial: 165.1 mg/dL; final: 163.5 mg/dL and initial: 109.0 mg/dL; final: 107.3 mg/dL, respectively. CONCLUSION: the nutritional treatment for children with short stature was effective in reducing stunting and improving TG and HDL-C after three years of intervention. However, the levels of LDL-C and TC remained high even in treated children. It is therefore speculated that these changes may result from metabolic programming due to malnutrition.

    Full Text Available Introduction: Premedication with midazolam can occasionally result in increased pediatric anxiety. In this study, we compared the effects of intravenous midazolam and fentanyl as pediatric premedication in children posted for inguinal hernia surgery. Methods: In this double blind randomized clinical trial study, sixty pediatric patients were randomly allocated to two study groups. Anesthesia was similar in both groups. Sedation score by Richmond agitation sedation scale was repeatedly measured on arrival to the preoperative part of the operating room, during drug administration, separation of the child from parent for transfer to the operating room, induction of anesthesia, time of transfer to the recovery room and discharge from the recovery room. Post-operative nausea and vomiting was also recorded. The collected data was analyzed with SPSS 15 and P value<0.05 was considered meaningful. Results: Baseline characteristics of the two study groups were similar. Mean RASS at separation of patients from parents; the time between the study drug administrations till separation from parents, induction of anesthesia and end of operation and need for additional drug during separation was significantly lower in the midazolam group. Opioid need in the fentanyl group was higher. Other findings were similar in the two groups. Conclusion: Use of fentanyl instead of midazolam as a premedication is not a priority in children posted for surgery.

    Full Text Available Introduction: Hearing is one of the premier human senses. Being deprived from hearing is not only being unable to hear the sounds, but it is also the disability to gain a lot of helpful experiences. Cochlear implantation is introduced worldwide in order to treat the severe to profound hearing loss. Therefore, the present study aims to determine the effect of age of cochlear implantation on improvement of the auditory performance. Methods: The present follow-up study was conducted on 96 children who had referred to Fars Cochlear Implantation Center. The patients’ information was gathered from their profiles both before and after the operation. In addition, the auditory performance score was obtained in 3 stages – 6 months, 1 year, and 2 years after the implantation – through the Cap test. Also, non-parametric tests of Fridman, Willcoxon, and Mann-Withney U were utilized in order to analyze the data of the study. Results: The mean of the children’s auditory performance 6 months, 1 year, and 2 years after the implantation was measured as 2.8+1.03, 4.36+1.04, and 5.34+1.02, respectively. Besides, the median of their auditory performance 6 months, 1 year, and 2 years after the implantation was calculated as 3, 5, and 5, respectively. Also, a statistically significant relationship was observed between the independent variable of age of cochlear implantation and the auditory performance score 6 months, 1 year, and 2 years after the implantation. Conclusion: In line with other studies conducted on the issue, the present study showed the improvement of the auditory performance in the children who benefited from cochlear implantation. Moreover, the results of the present study revealed that the age of cochlear implantation can be of great help in determining the candidates of cochlear implantation. In other words, it can be a major prognostic factor of the response to the treatment

    Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Staphylococcus aureus colonization of the adenoids and nasopharynx in 103 preschool children who underwent adenoidectomy for recurrent upper respiratory tract infections was examined. Bacterial interactions and risk factors for bacterial colonization of the nasopharynx and adenoids, separately, were analysed statistically. The prevalence of simultaneous isolation from both anatomical sites was 45·6% for S. pneumoniae, 29·1% for H. influenzae, 15·5% for M. catarrhalis and 18·4% for S. aureus. Three pathogens were significantly more frequent together from adenoid samples; nasopharyngeal swabs more often yielded a single organism, but without statistical significance. M. catarrhalis and S. aureus significantly more frequently co-existed with S. pneumoniae and H. influenzae than with each other and a positive association of S. pneumoniae and H. influenzae in adenoid samples was evident. Several differences between risk factors for nasopharyngeal and adenoid colonization by the individual pathogens were observed. We conclude that the adenoids and nasopharynx appear to differ substantially in colonization by pathogenic microbes but occurrence of H. influenzae and S. pneumoniae in the nasopharynx could be predictive of upper respiratory tract infections.

    Objective: The purpose of this study was to compare the diagnostic accuracy of 64-slice CT with that of invasive angiography in the detection of graft and/or coronary angioplasty stenosis in children who had undergone coronary artery surgery. Population and methods: Fifteen consecutive children (8 male and 7 female; age 9.2 {+-} 6.1 years) underwent 64-slice CT because of chest pain or ECG changes mean 4.8 {+-} 3.7 years after surgical coronary artery surgery; 10 patients had coronary angioplasty using a patch from the saphenous vein, four had mammary artery bypass, and one had saphenous vein bypass. Six main segments of the coronary arteries and all the bypass graft considered as a single segment were analyzed and compared with invasive angiography used as the reference standard. Results: CT correctly identified the four children with coronary angioplasty and mammary graft lesions that were confirmed by conventional angiography: one patient had a significant stenosis (>50% stenosis) at the mammary bypass graft anastomosis site; three other had non-significant stenosis (<50% stenosis) including a mild lesion of the saphenous vein patch in two patients and a mild lesion at the anastomosis site of the mammary bypass in one. All segments identified as normal by CT in the other 11 children were also found to be normal by conventional angiography. Conclusion: In centers expert in this technique, 64-slice CT scanning is a promising, rapid, and useful diagnostic technique for evaluating both coronary angioplasty and bypass graft lesions in children who had undergone coronary artery surge0008.

    Fab fragments of antibodies specific for cardiac myosin have been labeled with indium-111 and injected intravenously into animals and into patients with heart transplants. The antibodies, developed by Khaw, Haber, and co-workers, localize in cardiac myocytes that have been damaged irreversibly by ischemia, myocarditis, or the rejection process. After clearance of the labeled antibody from the cardiac blood pool, planar imaging or single photon emission computed tomography is performed. Scintigrams reveal the uptake of the labeled antimyosin in areas of myocardium undergoing transplant rejection. In animal studies, the degree of antimyosin uptake appears to correlate significantly with the degree of rejection assessed at necropsy. In patients, the correlation between scans and pathologic findings from endomyocardial biopsy is not as good, possibly because of sampling error in the endomyocardial biopsy technique. The scan results at 1 year correlate with either late complications (positive) or benign course (negative). Current limitations of the method include slow blood clearance, long half-life of indium-111, and hepatic uptake. Overcoming these limitations represents a direction for current research. It is possible that from these efforts a noninvasive approach to the diagnosis and evaluation of cardiac transplantation may evolve that will decrease the number of endomyocardial biopsies required to evaluate rejection. This would be particularly useful in infants and children. 31 references.

    Full Text Available Introduction: Human immunodeficiency virus (HIV infection is a primary cause of acquired heart disease, particularly of accelerated atherosclerosis, symptomatic heart failure, and pulmonary arterial hypertension. Cardiac complications often occur in late-stage HIV infections as prolonged viral infection is becoming more relevant as longevity improves. Thus, multi-agent HIV therapies that help sustain life may also increase the risk of cardiovascular events and accelerated atherosclerosis. Discussion: Before highly active antiretroviral therapy (HAART, the two-to-five-year incidence of symptomatic heart failure ranged from 4 to 28% in HIV patients. Patients both before and after HAART also frequently have asymptomatic abnormalities in cardiovascular structure. Echocardiographic measurements indicate left ventricular (LV systolic dysfunction in 18%, LV hypertrophy in 6.5%, and left atrial dilation in 40% of patients followed on HAART therapy. Diastolic dysfunction is also common in long-term survivors of HIV infection. Accelerated atherosclerosis has been found in HIV-infected young adults and children without traditional coronary risk factors. Infective endocarditis, although rare in children, has high mortality in late-stage AIDS patients with poor nutritional status and severely compromised immune systems. Although lymphomas have been found in HIV-infected children, the incidence is low and cardiac malignancy is rare. Rates of congenital cardiovascular malformations range from 5.6 to 8.9% in cohorts of HIV-uninfected and HIV-infected children with HIV-infected mothers. In non-HIV-infected infants born to HIV-infected mothers, foetal exposure to ART is associated with reduced LV dimension, LV mass, and septal wall thickness and with higher LV fractional shortening and contractility during the first two years of life. Conclusions: Routine, systematic, and comprehensive cardiac evaluation, including a thorough history and directed laboratory

    Full Text Available BACKGROUND: The effects of physical therapy on heart rate variability (HRV, especially in children, are still inconclusive. OBJECTIVE: We investigated the effects of conventional physical therapy (CPT for airway clearance and nasotracheal suction on the HRV of pediatric patients with acute bronchiolitis. METHOD: 24 children were divided into two groups: control group (CG, n=12 without respiratory diseases and acute bronchiolitis group (BG, n=12. The heart rate was recorded in the BG at four different moments: basal recording (30 minutes, 5 minutes after the CPT (10 minutes, 5 minutes after nasotracheal suction (10 minutes, and 40 minutes after nasotracheal suction (30 minutes. The CG was subjected to the same protocol, except for nasotracheal suction. To assess the HRV, we used spectrum analysis, which decomposes the heart rate oscillations into frequency bands: low frequency (LF=0.04-0.15Hz, which corresponds mainly to sympathetic modulation; and high frequency (HF=0.15-1.2Hz, corresponding to vagal modulation. RESULTS: Under baseline conditions, the BG showed higher values in LF oscillations, lower values in HF oscillations, and increased LF/HF ratio when compared to the CG. After CPT, the values for HRV in the BG were similar to those observed in the CG during basal recording. Five minutes after nasotracheal suction, the BG showed a decrease in LF and HF oscillations; however, after 40 minutes, the values were similar to those observed after application of CPT. CONCLUSIONS: The CPT and nasotracheal suction, both used for airway clearance, promote improvement in autonomic modulation of HRV in children with acute bronchiolitis.

  12. Non-invasive assessment of congenital pulmonary vein stenosis in children using cardiac-non-gated CT with 64-slice technology

    International Nuclear Information System (INIS)

    Background: Management of congenital pulmonary vein stenosis is a diagnostic challenge. Echocardiography may be insufficient and thus cardiac catheterization remains the reference standard in this setting. The aim of the study was to investigate the accuracy of cardiac-non-gated CT using 64-slice technology in detecting congenital pulmonary vein stenosis in children. Materials and methods: CT examinations were consecutively performed from May 2005 to December 2006 in 13 children aged 1.5-12 months (median 5 months) for suspected congenital pulmonary vein stenosis. Cardiac-non-gated CT acquisitions were performed after the peripheral injection of contrast agent. Pulmonary veins were evaluated for their pattern of connectivity from the lung to the left atrium and for the presence of stenosis. CT findings of pulmonary vein stenosis were compared with combined findings available from echocardiography, catheterization and surgery. Results: Pulmonary veins from the right lung (n = 29) and left lung (n = 26) were evaluated as separate structures (N = 55). Of the 55 structures, 32 had surgical and/or catheterization data and 45 had echocardiography for comparison. CT visualized 100% (55/55) of the investigated structures, while echocardiography visualized 82% (45/55). In the 13 subjects CT identified 10 stenotic pulmonary veins. CT confirmed the echocardiography suspicion of pulmonary vein stenosis in 100% (7/7) and established a new diagnosis in 3 other patients. CT agreed with surgery/catheterization in 100% (10/10) of the available comparisons. Conclusion: Cardiac-non-gated CT assessed the pulmonary veins more completely than echocardiography and should be considered as a viable alternative for invasive pulmonary venography for detecting pulmonary vein stenosis in children.

    Objective: To study the correlation of low-dose 64-row multi-detector computed tomography (MDCT) with echocardiography and cardiac catheterization angiography (CCA) in the assessment of pulmonary arterial anatomy in children with cyanotic congenital heart disease (CCHD). Materials and methods: This prospective study included 105 children (74 males, 31 females) with CCHD, in the age group of 2 months to 20 years, who underwent 64-row MDCT examination (low-dose CT protocol), echocardiography and CCA for the assessment of pulmonary arteries, including visualization, presence of confluence, stenosis and collaterals. Statistical analysis was performed using the non-parametric statistical analysis test to evaluate the concordance or discordance between echocardiography, MDCT and CCA. Results: 64-row MDCT detected significantly more main and branch pulmonary arteries, patent pulmonary confluences, and more cases of pulmonary artery stenosis. CCA detected more major aorto-pulmonary collaterals than MDCT, whereas echocardiography failed to identify these major aorto-pulmonary collaterals. The effective CT radiation dose to patients less than 2 years of age was in the range of 0.7–2.5 mSv, where as the dose in patients more than 2 years of age ranged from that of 2.1 to 4.2 mSv, which is much less than the radiation dose reported in cardiac catheterization angiography. Conclusion: In cases where cardiac MRI cannot be performed, or is not sufficiently informative, low-dose 64-row MDCT correlates well with CCA and can provide adequate information about pulmonary arterial anatomy in children with cyanotic congenital heart disease, and can replace invasive cardiac catheterization angiography with markedly reduced radiation dosage to the patient.

    Full Text Available The Coronary Artery Risk Detection In Appalachian Communities (CARDIAC Project has screened more than 80,000 children (10–12 years for cardiovascular and diabetes risk factors over the past 15 years. Simultaneous referral and intervention efforts have also contributed to the overall program impact. In this study, we examined evidence of programmatic impact in the past decade at the individual, family, community, and policy levels from child screening outcomes, referral rates, participation in subsequent services, and policies that embed the activities of the project as a significant element. Within this period of time, fifth-grade overweight and obesity rates were maintained at a time when rates elsewhere increased. 107 children were referred for additional screening and treatment for probable familial hypercholesterolemia (FH; 82 family members were subsequently screened in family-based screening efforts. 58 grants were distributed throughout the state for community-appropriate obesity intervention. A state wellness policy embedded CARDIAC as the method of assessment and national child cholesterol screening guidelines were impacted by CARDIAC findings. The sustainability and successful impact of this school-based program within a largely underserved, rural Appalachian state are also discussed.

    Full Text Available OBJECTIVE: To perform a systematic review and individual participant data meta-analysis to identify preoperative factors associated with a good seizure outcome in children with Tuberous Sclerosis Complex undergoing resective epilepsy surgery. DATA SOURCES: Electronic databases (MEDLINE, EMBASE, CINAHL and Web of Science, archives of major epilepsy and neurosurgery meetings, and bibliographies of relevant articles, with no language or date restrictions. STUDY SELECTION: We included case-control or cohort studies of consecutive participants undergoing resective epilepsy surgery that reported seizure outcomes. We performed title and abstract and full text screening independently and in duplicate. We resolved disagreements through discussion. DATA EXTRACTION: One author performed data extraction which was verified by a second author using predefined data fields including study quality assessment using a risk of bias instrument we developed. We recorded all preoperative factors that may plausibly predict seizure outcomes. DATA SYNTHESIS: To identify predictors of a good seizure outcome (i.e. Engel Class I or II we used logistic regression adjusting for length of follow-up for each preoperative variable. RESULTS: Of 9863 citations, 20 articles reporting on 181 participants were eligible. Good seizure outcomes were observed in 126 (69% participants (Engel Class I: 102(56%; Engel class II: 24(13%.

    Postoperative arrhythmia is a common complication after open heart surgery in children. JET is the most common and dangerous arrhythmia. We aimed to assess safety and efficacy of prophylactic amiodarone in preventing JET in children underwent cardiac surgery and to assess risk factors for JET among our patients. In total, 117 children who underwent cardiac surgery for CHD at Tanta University Hospital from October 2011 to April 2015 were divided in two groups; amiodarone group (65 patients) was given prophylactic amiodarone intraoperatively and placebo group (52 patients). Amiodarone is started as loading dose of 5 mg/kg IV in the operating room after induction of anesthesia and continued for 3 days as continuous infusion 10-15 μg/kg/min. Primary outcome and secondary outcomes of amiodarone administration were reported. We studied pre-, intra- and postoperative factors to determine risk factors for occurrence of JET among these children. Prophylactic amiodarone was found to significantly decrease incidence of postoperative JET from 28.9 % in placebo group to 9.2 % in amiodarone group, and symptomatic JET from 11.5 % in placebo group to 3.1 % in amiodarone group, and shorten postoperative intensive care unit and hospital stay without significant side effects. Risk factors for occurrence of JET were younger age, lower body weight, longer cardiopulmonary bypass, aortic cross-clamp time, hypokalemia, hypomagnesemia, acidosis and high dose of inotropes. JET was more associated with surgical repair of right ventricular outlet obstruction as in case of tetralogy of Fallot and pulmonary stenosis. Most of JET 15/21 (71.4 %) occurred in the first day postoperatively, and 6/21 occurred in the second day (28.6 %). Prophylactic amiodarone is safe and effective in preventing early JET in children after open heart surgery. PMID:26818850

  5. Introduction to cardiac imaging in infants and children: Techniques, potential, and role in the imaging work-up of various cardiac malformations and other pediatric heart conditions

    International Nuclear Information System (INIS)

    The increasing prevalence of congenital heart disease (CHD) can be attributed to major improvements in diagnosis and treatment. Although echocardiography is the most commonly used imaging modality for diagnosis and follow-up of subjects with CHD, the evolution of cardiovascular magnetic resonance (MR) imaging and increasingly computed tomography (CT) does offer new ways to visualize the heart and the great vessels. The development of cardiovascular MR techniques allows for a comprehensive assessment of cardiac anatomy and function. This provides information about the long-term sequlae of the underlying complex anatomy, hemodynamic assessment of residual post-operative lesions and complications of surgery. As much of the functional data in CHD patients is usually acquired with invasive X-ray angiography, non-invasive alternatives such as cardiovascular MR (and CT) are desirable. This review evaluates the role of MR imaging in the management of subjects with CHD, particularly detailing recent developments in imaging techniques as they relate to the various CHD diagnoses we commonly encounter in our practice

    Full Text Available BACKGROUND: There is a relative lack of studies on postoperative changes in nitrite (NO2 - concentrations, a marker of injury, following cardiac surgery. In this context, investigations on how exhaled NO concentrations vary in the postoperative period of cardiac surgery will certainly contribute to new clinical findings. OBJECTIVE: The objective of this study was to compare the EBC NO levels in both the pre and postoperative (24 hours periods of cardiac surgery. METHODS: Twenty - eight individuals were divided into three groups: 1 control, 2 coronary artery bypass grafting, and 3 valve surgery. The nitrite (NO2 - levels were measured by chemiluminescence in blood samples and exhaled breath condensate (EBC. Data were analyzed by the Mann - Whitney and Wilcoxon tests. RESULTS: 1 Preoperatively, the EBC NO2 - levels from groups 2 and 3 patients were higher than control individuals; 2 The postoperative (24 hours NO2 - levels in the EBC from group 3 patients were lower compared with preoperative values; 3 The NO2 - levels in the plasma from group 2 patients were lower in the preoperative compared with the postoperative (24h values and; 4 Preoperatively, there was no difference between groups 2 and 3 in terms of plasma NO2 - concentrations. CONCLUSION: These data suggest that NO measurement in EBC is feasible in cardiac surgery patients.INTRODUÇÃO: Estudos mostrando alterações das concentrações de nitrito (NO2 - exalado, com biomarcador de lesão, são raros em pacientes submetidos à cirurgia cardíaca.

  12. Left ventricular dyssynchrony assessed by gated SPECT phase analysis is an independent predictor of death in patients with advanced coronary artery disease and reduced left ventricular function not undergoing cardiac resynchronization therapy

    International Nuclear Information System (INIS)

    Left ventricular (LV) mechanical dyssynchrony (LVMD) was assessed by gated single-photon emission CT myocardial perfusion imaging (MPI) as an independent predictor of death from any cause in patients with known coronary artery disease (CAD) and reduced LV function. Between 2001 and 2010, 135 patients (64 ± 11 years of age, 84 % men) with known CAD, reduced LV ejection fraction (LVEF, 38 ± 15 %) and without an implanted cardiac resynchronization therapy device underwent gated MPI at rest. LV functional evaluation, which included phase analysis, was conducted to identify patients with LVMD. Kaplan-Meier survival curves were calculated for death of any cause during a mean follow-up of 2.0 ± 1.7 years. Uni- and multivariate Cox proportional hazards regression models were calculated to identify independent predictors of death from any cause. Of the 135 patients, 30 (22 %) died during follow-up (18 cardiac deaths and 12 deaths from other causes). Kaplan-Meier curves showed a significantly shorter survival time in the patients with severely reduced LVEF (<30 %, n = 45) or with LVMD (n = 81, log-rank test P <0.005). Cox models identified LVMD, LVEF <30 % and a total perfusion deficit at rest of ≥20 % as independent predictors of death from any cause. While patients with LVEF <30 % in conjunction with LVMD had similar survival times irrespective of whether they had early revascularization or medical therapy, those patients with LVEF ≥30% and LVMD who underwent revascularization had significantly longer survival. In patients with known CAD and reduced LV function, dyssynchrony of the LV is an independent predictor of death from any cause. (orig.)

    N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) is related to stress-induced myocardial ischemia and/or volume overload, both common in patients with renal dysfunction. This might compromise the prognostic usefulness of NT-pro-BNP in patients with renal impairment before vascular surgery. We assessed the prognostic value of NT-pro-BNP in the entire strata of renal function. In 356 patients (median age 69 years, 77% men), cardiac history, glomerular filtration rate (GFR, ml/min/1.73 m(2)), and NT-pro-BNP level (pg/ml) were assessed preoperatively. Troponin T and electrocardiography were assessed postoperatively on days 1, 3, 7, and 30. The end point was the composite of cardiovascular death, Q-wave myocardial infarction, and troponin T release. Multivariate analysis was used to evaluate the interaction between GFR, NT-pro-BNP and their association with postoperative outcome. Median GFR was 78 ml/min/1.73 m(2) and the median concentration of NT-pro-BNP was 197 pg/ml. The end point was reached in 64 patients (18%); cardiac death occurred in 7 (2.0%), Q-wave myocardial infarction in 34 (9.6%), and non-Q-wave myocardial infarction in 23 (6.5%). After adjustment for confounders, NT-pro-BNP levels and GFR remained significantly associated with the end point (p = 0.005). The prognostic value of NT-pro-BNP was most pronounced in patients with GFR > or =90 (odds ratio [OR] 1.18, 95% confidence interval [CI] 0.80 to 1.76) compared with patients with GFR 60 to 89 (OR 1.04, 95% CI 1.002 to 1.07), and with GFR 30 to 59 (OR 1.12, 95% CI 1.03 to 1.21). In patients with GFR discriminative value of NT-pro-BNP is most pronounced in patients with GFR > or =90 ml/min/1.73 m(2) and has no prognostic value in patients with GFR <30 ml/min/1.73 m(2).

    Over the past 10years cardiac troponin (cTn) immunoassays have been improved in analytical sensitivity and precision thereby allowing the measurement of cTn in adult healthy subjects. However, there are currently substantial gaps in our knowledge on circulating levels of cTn in healthy children. The aim of this study is to evaluate the distribution of plasma troponin concentration in apparently healthy pediatric subjects using a high sensitive immunoassay for cTnI measurement (hs-cTnI). Blood samples were obtained from 357 healthy pediatric subjects [204 males; age range 0-18years; mean (SD): 8.7(6) years], including 36 subjects aged LOD value were 13.1%. cTnI plasma levels were highest in the first month of life with a progressive decline in the next years and were lower in female. At multivariate analysis, only age was predictor of hs-cTnI plasma levels. The age and sex of children influence normal and physiologically released circulating concentrations of hs-cTnI, suggesting the need of reference intervals specific for age and sex. PMID:27118089

  19. Radiation detriment ascribable to infants and children undergoing micturating cystourethrograms - A review of studies in Spain, Britain, New Zealand and Venezuela

    International Nuclear Information System (INIS)

    The detriment, due to ionizing irradiation, ascribable to infants and children may be as high as three times that to adults. Recent interest in dose reduction, in part associated with the advent of the Diamentor dose-area product meter, has led to several studies reporting average dose-area products at a number of centres for micturating cystourethrograms (MCUGS) and other radiological examinations. In this review the data has been further processed to yield the ICRP 60 Equivalent Doses and a detriment factor applied to yield the numbers of infants and children likely to suffer detriment in future life as a result of having undergone the procedure at the centres reviewed.

    BACKGROUND: Neurodevelopmental disability is the most common complication for survivors of surgery for congenital heart disease (CHD). METHODS: We analyzed individual participant data from studies of children evaluated with the Bayley Scales of Infant Development, second edition, after cardiac surgery between 1996 and 2009. The primary outcome was Psychomotor Development Index (PDI), and the secondary outcome was Mental Development Index (MDI). RESULTS: Among 1770 subjects from 22 institutions, assessed at age 14.5 ± 3.7 months, PDIs and MDIs (77.6 ± 18.8 and 88.2 ± 16.7, respectively) were lower than normative means (each P < .001). Later calendar year of birth was associated with an increased proportion of high-risk infants (complexity of CHD and prevalence of genetic/extracardiac anomalies). After adjustment for center and type of CHD, later year of birth was not significantly associated with better PDI or MDI. Risk factors for lower PDI were lower birth weight, white race, and presence of a genetic/extracardiac anomaly (all P ≤ .01). After adjustment for these factors, PDIs improved over time (0.39 points/year, 95% confidence interval 0.01 to 0.78; P = .045). Risk factors for lower MDI were lower birth weight, male gender, less maternal education, and presence of a genetic/extracardiac anomaly (all P < .001). After adjustment for these factors, MDIs improved over time (0.38 points/year, 95% confidence interval 0.05 to 0.71; P = .02). CONCLUSIONS: Early neurodevelopmental outcomes for survivors of cardiac surgery in infancy have improved modestly over time, but only after adjustment for innate patient risk factors. As more high-risk CHD infants undergo cardiac surgery and survive, a growing population will require significant societal resources. PMID:25917996

    Children with systemic Juvenile Idiopathic Arthritis (sJIA), the most severe subtype of JIA, are at risk from destructive polyarthritis and growth failure, and corticosteroids as part of conventional treatment can result in osteoporosis and growth delay. In children where there is failure or toxicity from drug therapies, disease has been successfully controlled by T-cell-depleted autologous stem cell transplantation (ASCT). At present, the immunological basis underlying remission after ASCT is unknown. Immune reconstitution of T cells, B cells, natural killer cells, natural killer T cells and monocytes, in parallel with T-cell receptor (TCR) diversity by analysis of the β variable region (TCRVb) complementarity determining region-3 (CDR3) using spectratyping and sequencing, were studied in five children with sJIA before and after ASCT. At time of follow up (mean 11.5 years), four patients remain in complete remission, while one child relapsed within 1 month of transplant. The CD8(+) TCRVb repertoire was highly oligoclonal early in immune reconstitution and re-emergence of pre-transplant TCRVb CDR3 dominant peaks was observed after transplant in certain TCRVb families. Further, re-emergence of pre-ASCT clonal sequences in addition to new sequences was identified after transplant. These results suggest that a chimeric TCR repertoire, comprising T-cell clones developed before and after transplant, can be associated with clinical remission from severe arthritis. PMID:24405357

    The I-123 MIBG cardiac scintigraphy can assess norepinephrine uptake. It has been shown that cardiac adrenergic neuronal function was impaired in adults with dilated cardiomyopathy. The aim of this prospective study was to assess cardiac neuronal function in children with idiopathic dilated cardiomyopathy (DCM) and to compare cardiac uptake of I-123 MIBG with left ventricular ejection fraction (LVEF). We studied 26 consecutive patients with idiopathic DCM, aged 44 {+-} 50 months, and 12 controls, aged 49 {+-}65 months. A planar scintigraphy was performed in all children 4 hours after intravenous injection of 20 to 75 MBq of I-123 MIBG. A static anterior view was acquired for 10 minutes. Cardiac uptake of I-123 MIBG was expressed as the heart to mediastinum count ratio (HMR). Equilibrium radionuclide angiography was performed following a standard protocol. Cardiac uptake of I-123 MIBG was significantly decreased in patients with idiopathic DCM when compared with cardiac uptake in controls (172{+-}34% vs 277{+-}14%, P<0.0001). There was a good correlation between RCM and LVEF in patients with idiopathic DCM (y = 2.5 x +113.3, r = 0.80, P < 0.0001). In conclusion, cardiac neuronal function was impaired in children with idiopathic DCM and related to impairment of left ventricular function. (author)

    Sensorimotor cortex plasticity induced by constraint-induced movement therapy (CIMT) in six children (10.2±2.1 years old) with hemiplegic cerebral palsy was assessed by functional near-infrared spectroscopy (fNIRS). The activation laterality index and time-to-peak/duration during a finger-tapping task and the resting-state functional connectivity were quantified before, immediately after, and 6 months after CIMT. These fNIRS-based metrics were used to help explain changes in clinical scores of manual performance obtained concurrently with imaging time points. Five age-matched healthy children (9.8±1.3 years old) were also imaged to provide comparative activation metrics for normal controls. Interestingly, the activation time-to-peak/duration for all sensorimotor centers displayed significant normalization immediately after CIMT that persisted 6 months later. In contrast to this improved localized activation response, the laterality index and resting-state connectivity metrics that depended on communication between sensorimotor centers improved immediately after CIMT, but relapsed 6 months later. In addition, for the subjects measured in this work, there was either a trade-off between improving unimanual versus bimanual performance when sensorimotor activation patterns normalized after CIMT, or an improvement occurred in both unimanual and bimanual performance but at the cost of very abnormal plastic changes in sensorimotor activity.

  9. Estimation of children's radiation dose from cardiac catheterisations, performed for the diagnosis or the treatment of a congenital heart disease using TLD dosimetry and Monte Carlo simulation

    International Nuclear Information System (INIS)

    Entrance surface radiation doses were measured with thermoluminescent dosimeters for 98 children who were referred to a cardiology department for the diagnosis or the treatment of a congenital heart disease. Additionally, all the radiographic parameters were recorded and Monte Carlo simulations were performed for the estimation of entrance surface dose to effective dose conversion factors, in order to further calculate the effective dose for each child. For diagnostic catheterisations the values ranged from 0.16 to 14.44 mSv, with average 3.71 mSv, and for therapeutic catheterisations the values ranged from 0.38 to 25.01 mSv, with average value 5 mSv. Effective doses were estimated for diagnostic procedures and interventional procedures performed for the treatment of five different heart diseases: (a) atrial septal defect (ASD), (b) ventricular septal defect (VSD), (c) patent ductus arteriosus (PDA), (d) aorta coarctation and (e) pulmonary stenosis. The high levels of radiation exposure are, however, balanced with the advantages of cardiac catheterisations such as the avoidance of surgical closure and the necessity of shorter or even no hospitalisation.

    Minimizing the systemic inflammatory response caused by cardiopulmonary bypass is a major concern. It has been suggested that the perfusion temperature affects the inflammatory response. The aim of this prospective study was to compare the effects of moderate hypothermia (32°C) and normothermia (36°C) during cardiopulmonary bypass on markers of the inflammatory response and clinical outcomes (time on ventilator) after surgical closure of ventricular septal defects. During surgical closure of ventricular septal defects under cardiopulmonary bypass, 20 children (median age 4.9 months, range 2.3-38 months; median weight 7.2 kg, range 5.2-11.7 kg) were randomized to a perfusion temperature of either 32°C (Group 1, n = 10) or 36°C (Group 2, n = 10). The clinical data and blood samples were collected before cardiopulmonary bypass, directly after aortic cross-clamp release, and 4 and 24 h after weaning from cardiopulmonary bypass. Time on ventilation as primary outcome did not differ between the two groups. Other clinical outcome parameters like fluid balance or length of stay in the intensive care were also similar in the two groups. Compared with Group 2, Group 1 needed significantly higher and longer inotropic support (P Perfusion temperature did not influence cytokine release, organ injury, or coagulation. Cardiopulmonary bypass temperature does not influence time on ventilation or inflammatory marker release. However, in the present study, with a small patient cohort, patients operated under hypothermic bypass needed higher and longer inotropic support. The use of hypothermic cardiopulmonary bypass in infants and children should be approached with care. PMID:26581834

    Bronchiolitis obliterans syndrome (BOS) is a devastating complication after allogeneic stem cell transplantation (allo-SCT). Early identification of high-risk patients is pivotal for success. Lung proteins, KL-6, CCSP, SP-A, and SP-D, measured in the serum may identify high-risk patients for BOS earlier than pulmonary function tests (PFTs) can identify changes or clinical symptoms. Lung proteins were measured in patients' serum at baseline and at 1, 3, 6, 9, 12, 18, and 24 months after transplantation along with history, clinical examination, and PFTs. Serum levels of lung proteins were also measured in healthy control subjects. The primary endpoint was the development of BOS confirmed by pathological biopsy or National Institutes of Health criteria. Between September 2009 and September 2011, 39 patients were enrolled. Six children developed BOS at a median time of 200 days (range, 94 to 282). KL-6 levels were low in control subjects, at a median of .1 U/mL (range, .1 to 1.5). Pre-SCT and 1-month KL-6 levels were significantly higher in surviving patients who developed BOS (n = 6) versus those who did not (n = 18) (pre-SCT: mean, 32.6 U/mL [IQR, 9.7 to 89.3] versus 5.8 U/mL [IQR, 2.1 to 12.6], P = .03; at 1 month: mean, 52.5 U/mL [IQR, 20.2 to 121.3] versus 11.4 U/mL [IQR, 5.7 to 36.0], P = .04). Three- and 6-month KL-6 levels continued to be higher in BOS group but were not statistically significant. CCSP, SP-A, and SP-D were not predictive. KL-6 measured in the serum of children receiving allo-SCT may identify patients at high risk for the development of BOS. These patients will benefit from intensive surveillance protocol and early therapy before irreversible lung damage. PMID:25963919

There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

  2. Coronary artery visibility in free-breathing young children with congenital heart disease on cardiac 64-slice CT: dual-source ECG-triggered sequential scan vs. single-source non-ECG-synchronized spiral scan

    International Nuclear Information System (INIS)

    The potential impact of dual-source ECG-triggered sequential CT scan on coronary artery visibility has not been evaluated in free-breathing young children. To compare coronary artery visibility in free-breathing young children with congenital heart disease on cardiac 64-slice CT between dual-source ECG-triggered sequential (DSET) scan and single-source non-ECG-synchronized spiral (SSNE) scan. In 93 young children, 108 cardiac 64-slice CT examinations were performed during free-breathing. Visibility of coronary arteries and side branches was compared between SSNE and DSET scans. Heart rates and trigger delays for DSET scan were recorded. Effective dose of each scan technique was calculated. Visual grades were significantly higher (P < 0.001 or =0.011) on DSET scan than on SSNE scan except for the distal left anterior descending artery. Coronary arteries were traceable in 79.3% on DSET scan and 54.3% on SSNE scan in the overlapped scan range (P < 0.0001), and 97.1% and 71.9% for the origins and proximal segments (P < 0.0001). Visibility of side branches was improved on DSET scan by a factor of 2.0. Heart rates and trigger delays for DSET scan were 131 ± 24 beats per min and 199 ± 44 ms, respectively. Effective doses of DSET and SSNE scans were 0.36 ± 0.12 mSv and 0.99 ± 0.23 mSv, respectively. DSET scan improves visibility of coronary arteries on cardiac 64-slice CT in free-breathing young children with congenital heart disease, compared with SSNE scan. (orig.)

  4. Direct measurement of a patient's entrance skin dose during pediatric cardiac catheterization

    International Nuclear Information System (INIS)

    Children with complex congenital heart diseases often require repeated cardiac catheterization; however, children are more radiosensitive than adults. Therefore, radiation-induced carcinogenesis is an important consideration for children who undergo those procedures. We measured entrance skin doses (ESDs) using radio-photoluminescence dosimeter (RPLD) chips during cardiac catheterization for 15 pediatric patients (median age, 1.92 years; males, n = 9; females, n = 6) with cardiac diseases. Four RPLD chips were placed on the patient's posterior and right side of the chest. Correlations between maximum ESD and dose-area products (DAP), total number of frames, total fluoroscopic time, number of cine runs, cumulative dose at the interventional reference point (IRP), body weight, chest thickness, and height were analyzed. The maximum ESD was 80 ± 59 (mean ± standard deviation) mGy. Maximum ESD closely correlated with both DAP (r = 0.78) and cumulative dose at the IRP (r = 0.82). Maximum ESD for coiling and ballooning tended to be higher than that for ablation, balloon atrial septostomy, and diagnostic procedures. In conclusion, we directly measured ESD using RPLD chips and found that maximum ESD could be estimated in real-time using angiographic parameters, such as DAP and cumulative dose at the IRP. Children requiring repeated catheterizations would be exposed to high radiation levels throughout their lives, although treatment influences radiation dose. Therefore, the radiation dose associated with individual cardiac catheterizations should be analyzed, and the effects of radiation throughout the lives of such patients should be followed. (author)

    Full Text Available Introduction Sudden cardiac death in athletes is a growing problem, despite the huge existing knowledge in medicine and sports. Effects of vigorous physical activity In response to vigorous physical activity, the body undergoes profound morphologic and functional changes. These changes are usually healthy, but sometimes may gravitate to some cardiac diseases. But still, most sudden cardiac deaths are due to previous unknown diseases. Causes of sudden cardiac death The most common cause of sudden cardiac death in athletes is hypertrophic cardiomyopathy. Other reasons are congenital coronary artery anomalies, myocarditis, dilatative cardiomyopathy, arrhythmogenic cardiomyopathy of the right ventricle, sarcoidosis, mitral valve prolapse, aortic valve stenosis, atherosclerosis, long QT syndrome, and blunt impact to the chest. Conclusion Bearing in mind the above mentioned, more frequent physical examinations of athletes are recommended.

    Children undergoing cardiac surgery requiring cardiopulmonary bypass (CPB) frequently develop acute kidney injury due to renal ischemia. Theophylline, which improves renal perfusion via adenosine receptor inhibition, is a potential targeted therapy. However, children undergoing cardiac surgery and CPB commonly have alterations in drug pharmacokinetics. To help understand optimal aminophylline (salt formulation of theophylline) dosing strategies in this population, a population-based pharmacokinetic model was developed using nonlinear mixed-effects modeling (NONMEM) from 71 children (median age 5 months; 90% range 1 week to 10 years) who underwent cardiac surgery requiring CPB and received aminophylline as part of a previous randomized controlled trial. A 1-compartment model with linear elimination adequately described the pharmacokinetics of theophylline. Weight scaled via allometry was a significant predictor of clearance and volume. In addition, allometric scaled clearance increased with age implemented as a power maturation function. Compared to prior reports in noncardiac children, theophylline clearance was markedly reduced across age. In the final population pharmacokinetic model, optimized empiric dosing regimens were developed via Monte Carlo simulations. Doses 50% to 75% lower than those recommended in noncardiac children were needed to achieve target serum concentrations of 5 to 10 mg/L. PMID:26712558

    Objective To discuss the early diagnosis and treatment of cardiac penetrating injuries and pseudoaneurysm. Methods 18 cases of cardiac penetrating injuries, in which 2 cases were complicated with pseudoaneurysm, were diagnosed by emergency operation and color Doppler echocardiography between May 1973 and Dec. 2001 in our hospital. The basis for emergency operation is the injured path locating in cardiac dangerous zone, severe shock or pericardial tamponade. ResultsAmong 18 cases of this study, 17 cases underwent emergency operation. During the operation, 11 cases were found injured in right ventricle, 2 cases were found injured in right atrium, 1 case was found injured in pulmonary artery,4 cases were found injured in left ventricle, 2 cases were found complicated with pseudoaneurysm. 17cases underwent cardiac repair including 1 case of rupture of aneurysm. 1 case underwent elective aneurysm resection. In whole group, 15 cases survived(83.33% ), 3 cases died( 16.67%). The cause of death is mainly hemorrhagic shock. Conclusion Highly suspicious cardiac penetrating injuries or hemopericaridium should undergo direct operative exploration. Pseudoaneurysm should be resected early,which can prevent severe complications.

  10. Physiological and pathological cardiac hypertrophy.

    The heart must continuously pump blood to supply the body with oxygen and nutrients. To maintain the high energy consumption required by this role, the heart is equipped with multiple complex biological systems that allow adaptation to changes of systemic demand. The processes of growth (hypertrophy), angiogenesis, and metabolic plasticity are critically involved in maintenance of cardiac homeostasis. Cardiac hypertrophy is classified as physiological when it is associated with normal cardiac function or as pathological when associated with cardiac dysfunction. Physiological hypertrophy of the heart occurs in response to normal growth of children or during pregnancy, as well as in athletes. In contrast, pathological hypertrophy is induced by factors such as prolonged and abnormal hemodynamic stress, due to hypertension, myocardial infarction etc. Pathological hypertrophy is associated with fibrosis, capillary rarefaction, increased production of pro-inflammatory cytokines, and cellular dysfunction (impairment of signaling, suppression of autophagy, and abnormal cardiomyocyte/non-cardiomyocyte interactions), as well as undesirable epigenetic changes, with these complex responses leading to maladaptive cardiac remodeling and heart failure. This review describes the key molecules and cellular responses involved in physiological/pathological cardiac hypertrophy. PMID:27262674

    Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances.Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006.Study selection Relevant articles on studies of cardiac troponin were selected.Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high (about 5 times above normal). On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted.Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the "golden cardiac marker' of this time.

    Objective To describe changes in body composition of children during acute period after hematopoietic stem transplantation and to analyze their related factors. Methods From January to September 2012,40 patients undergoing hematopoietic stem cell transplantation in Shanghai Children's Medical Center were prospectively enrolled into the study. Height, weight and body composition were measured by direct segmental multi-frequency bioelectrical impedance analysis (DSM-BIA) were recorded before transplantation and at the 30th, 60th and 100th day after transplantation. Sex, age, transplantation method, graft source,total body irradiation,use of methylprednisolone, infection, the grade of mucositis and acute graft-versus-host disease (aGVHD) grade were also recorded. Results After hematopoietic stem cell transplantation, no significant change was observed in height Z-scores (F=0. 75,P = 0. 3883); body mass index(BMI) Z-values and fat-free mass for height (FFM-Ht) were significantly decreased but fat mass for height(FM-Ht) was also significantly increased(P<0. 05 or P<0. 01). After controlling children's age, the graft source was a significant factor affecting BMI Z and the total body irradiation was a significant factor affecting FM-Ht and infection was the a risk factor of FFM-Ht. Conclusion Children have high risks of emaciation and obesity during the acute period after hematopoietic stem cell transplantation. Irradiation may increase their fat mass, while infection may decreases fat-free mass. BMI may not be a good indicator to assess nutrition status of children undergoing transplantation.%目的 了解造血干细胞移植患儿急性期的人体组分变化情况并分析其相关因素.方法 前瞻性收集2012年1月至2012年9月在上海儿童医学中心进行造血干细胞移植的40例患儿的临床资料,在患儿进行造血干细胞移植前、移植后的第30、60和100天测量其身高、体质指数及使用直接节段多频生物电阻抗分析

  3. Conventional and CT angiography in children: dosimetry and dose comparisons

    International Nuclear Information System (INIS)

    Tremendous advances have been made in imaging in children with both congenital and acquired heart disease. These include technical advances in cardiac catheterization and conventional angiography, especially with advancements in interventional procedures, as well as noninvasive imaging with MR and CT angiography. With rapid advances in multidetector CT (MDCT) technology, most recently 64-detector array systems (64-slice MDCT), have come a number of advantages over MR. However, both conventional and CT angiography impart radiation dose to children. Although the presence of radiation exposure to children has long been recognized, it is apparent that our ability to assess this dose, particularly in light of the rapid advancements, has been limited. Traditional methods of dosimetry for both conventional and CT angiography are somewhat cumbersome or involve a potential for substantial uncertainty. Recent developments in dosimetry, including metal oxide semiconductor field effect transistors (MOSFET) and the availability of anthropomorphic, tissue-equivalent phantoms have provided new opportunities for dosimetric assessments. Recent work with this technology in state-of-the-art cardiac angiography suites as well as with MDCT have offered direct comparisons of doses in infants and children undergoing diagnostic cardiac evaluation. It is with these dose data that assessment of risks, and ultimately the assessment of risk-benefit, can be better achieved. (orig.)

When a child undergoes a median sternotomy during cardiac surgery, most of the thymus is removed to gain access to the mediastinum. What happens to the residual thymic tissue in the long term ?To test the hypothesis that residual thymic tissue left after sternotomy regenerates into an identifiable thymus and is visible on MRI. We retrospectively reviewed the cardiac MR images obtained over a 14-month period in all children under the age of 17 years who had undergone a median sternotomy (n=62) to establish the presence/absence of a thymus. We also reviewed the cardiac MR images obtained over the same time period in children who had never undergone open cardiac surgery (n=37). In the sternotomy group, 18 patients (29%) had an identifiable thymus on MR images, compared to 92% (n=34) in the nonsternotomy group. This difference was statistically significant. The majority of children in the study group did not have a visible thymus on MR images, which suggests that in these children any residual thymic tissue left postoperatively does not regenerate.

    Paediatric cardiac catheterizations may result in the administration of substantial amounts of iodinated contrast media and ionizing radiation. The aim of this work was to investigate the effect of iodinated contrast media in combination with in vitro and in vivo X-ray radiation on lymphocyte DNA. Six concentrations of iodine (15, 17.5, 30, 35, 45, and 52.5 mg of iodine per mL blood) represented volumes of iodinated contrast media used in the clinical setting. Blood obtained from healthy volunteers was mixed with iodinated contrast media and exposed to radiation doses commonly used in paediatric cardiac catheterizations (0 mGy, 70 mGy, 140 mGy, 250 mGy and 450 mGy). Control samples contained no iodine. For in vivo experimentation, pre and post blood samples were collected from children undergoing cardiac catheterization, receiving iodine concentrations of up to 51 mg of iodine per mL blood and radiation doses of up to 400 mGy. Fluorescence microscopy was performed to assess γH2AX-foci induction, which corresponded to the number of DNA double-strand breaks. The presence of iodine in vitro resulted in significant increases of DNA double-strand breaks beyond that induced by radiation for ≥ 17.5 mg/mL iodine to blood. The in vivo effects of contrast media on children undergoing cardiac catheterization resulted in a 19% increase in DNA double-strand breaks in children receiving an average concentration of 19 mg/mL iodine to blood. A larger investigation is required to provide further information of the potential benefit of lowering the amount of iodinated contrast media received during X-ray radiation investigations.

    Full Text Available Background: Post-operative fever is a common complication of cardiac operations, which is known to be correlated with a greater degree of cognitive dysfunction 6 weeks after cardiac surgery. The aim of the present study was to examine efficacy and safety of single dose intravenous Paracetamol in treatment of post-operative fever in children undergoing cardiac surgery. Materials and Methods: In this randomised, double-blind, placebo-controlled clinical trial, 80 children, aged 1-12 years, presenting for open heart surgery were entered in the trial and randomly allocated into two groups: Placebo and Paracetamol. After induction of anaesthesia, 15 mg/kg intravenous Paracetamol solution was infused during 1 h in the Paracetamol group. Patients in placebo group received 15 mg/kg normal saline infusion during the same time. Since the end of operation until next 24 h in intensive care unit, axillary temperature of the two group patients was recorded in 4-h intervals. Any fever that occurred during this period had been treated with Paracetamol suppository (125 mg and the amount of antipyretic drug consumption for each patient had been recorded. In order to examine the safety of Paracetamol, patients were evaluated for drug complication at the same time. Results: Mean axillary temperature during first 24 h after operation was significantly lower in Paracetamol group compared with placebo group (P = 0.001. Overall fever incidence during 24 h after operation was higher in placebo group compared with Paracetamol group (P = 0.012. Of Paracetamol group patients, 42.5% compared with 15% of placebo group participants had no consumption of antipyretic agent (Paracetamol suppository during 24 h after operation (P = 0.001. Conclusion: This study suggests that single dose administration of intravenous Paracetamol before paediatric cardiac surgeries using cardiopulmonary bypass; reduce mean body temperature in the first 24 h after operation.

The aim of this study is to examine the significance of abnormal RVEF by cardiac magnetic resonance (CMR, independent of LVEF in predicting outcomes of patients undergoing isolated CABG and valve surgery.From 2007 to 2009, 109 consecutive patients (mean age, 66 years; 38% female were referred for pre-operative CMR. Abnormal RVEF and LVEF were considered 30 days outcomes included, cardiac re-hospitalization, worsening congestive heart failure and mortality. Mean clinical follow up was 14 months.Forty-eight patients had reduced RVEF (mean 25% and 61 patients had normal RVEF (mean 50% (p<0.001. Fifty-four patients had reduced LVEF (mean 30% and 55 patients had normal LVEF (mean 59% (p<0.001. Patients with reduced RVEF had a higher incidence of long-term cardiac re-hospitalization vs. patients with normal RVEF (31% vs.13%, p<0.05. Abnormal RVEF was a predictor for long-term cardiac re-hospitalization (HR 3.01 [CI 1.5-7.9], p<0.03. Reduced LVEF did not influence long-term cardiac re-hospitalization.Abnormal RVEF is a stronger predictor for long-term cardiac re-hospitalization than abnormal LVEF in patients undergoing isolated CABG and valve procedures.

    Objective Non-pharmacological approaches to pain management have been used by therapists for decades to reduce the anxiety and pain experienced by children during burn care procedures. With a greater understanding of pain and the principles behind what causes a child to be distracted, com-bined with access to state of the art technology, we have developed an easy to use, hand held multimodal distraction device (MMD). MMD is an interactive device that prepares the child for a procedure and uses developmentally appropriate distraction stories and games during the procedures to alleviate anxiety and pain. This paper summarizes the results of three randomized control trials. The trials aimed to understand the effec-tiveness of MMD as a distraction and preparation tool in reducing anxiety and pain in children undergoing burns and non-burns medical procedures compared to pure pharmacological approaches Standard Distraction (SD) and off the shelf video games (VG). Methods Three separate prospective randomized control tri-als involving 182 children having 354 dressing changes were conducted in the burns and orthopedic depart-ments at Royal Children's Hospital, Brisbane, Australia, to address the above aims. Pain and anxiety scores were completed for the child, caregivcr and nursing staff according to the Modified Faces, Legs, Activity, Cry and Consolability Scale, Faces Pain Scale-Revised, Visual Analogue Scale and Wong-Baker Faces Pain Rating Scale. Procedural length was recorded. Results MMD as a preparation and distraction tool were shown to have a significant impact on child, parent and nursing staff reported anxiety and pain daring proce-dures compared to standard care and video games (P<0.01). The MMD had a positive effect on clinical time and was shown to sustain its impact on pain and time with further dressing changes. Conclusions MMD is more effective in reducing the pain and anxiety experienced by children in acute medical procedures as compared with SD and VG

    Objective To investigate the myocardial protection effects of radical scavenger edaravone(MCI-186) combined with fructose-1, 6-diphosphate(FDP) in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB). Methods Forty patients with rheumatic heart disease undergoing mitral,aortic,mitral or aortic valve replacement were randomly divided into four groups: control group (group A),group MCI-186 g(group B),group FDPCgroup C),MCI-186 and FDP combination group (group D, 72=10 each). The same volume of saline solution was infused intravenously in group A. Group B received edaravone injection 0. 5 mg/kg in cardioplegia solution. 200 mg/kg FDP was intravenously infused before aorta-clamping in group C. Edaravone 0. 5 mg/kg was mixed with CPB priming fluid and FDP 200 mg/kg was given intravenously 15 min before aortic cross clamp in group D. Plasma activity of superoxide dismulase (SOD) and levels of malondialdehyde (MDA), creatinekinase-MB and cardiac troponin I were measured before skin incision (T1), before aortic-clamping(T2), at 2 h and 6 h after CPB and 24 h postoperative (T3-T5). Meanwhile, the clinical effectiveness of each group was observed. Results Compared with T1, SOD activity decreased significantly at T2-T4in group A, while the levels of serum MDA, CK-MB at T3-T5 and cTnl at T2-T5 increased significantly in all groups(P<0. 05). Compared with group A, SOD activity at T2-T4 increased significantly, while levels of serum MDA and CK-MB at T3-T5 decreased in other groups, the levels of cTnl in group B,C,D at T3 and in group B,D at T4 were obviously decreased. (P<0. 05 or P <0. 01). The concentration of cTnl in group B and C was obviously higher than that in group D at T3 ,T4 (P<0. 05). The consumption of dopa mine and drainage quantity within 24 h after surgery were much more in group A than those in group D(P<0. 05). Conclusion Edaravone and FDP has notable protective effect on myocardial ischemia and reperfusion injury, especially when

  19. Ultrafast MR imaging with EPI of organs undergoing nonperiodic motion

    International Nuclear Information System (INIS)

    Conventional MR imaging employing repetitive data acquisition is susceptible to motion artifacts. Gating overcomes periodic motion effects. Nonperiodic motion, as encountered in the gastronintestinal tract, cardiac arrhythmias, unsedated children, and fetal imaging, thwarts conventional MR imaging. The EPI derivatives BEST and MBEST create a complex 128 x 128-pixel image in 64 msec and 128 msec, respectively, freezing motion almost completely. Sequentially recorded gastrointestinal-tract images allow quantitative evaluation of gastric and gut motility. Cardiac morphology, movement, and blood flow patterns in valvular heart disease have been depicted during atrial fibrillation. Selected clinical results with accompanying technical details illustrate the scope of EPI as a distinctive imaging modality

    Full Text Available Pediatric cardiac surgery is undergoing a metamorphosis, with more and more critical patients being operated in our country today. Although the principles of physiology have not changed, it is imperative that care providers continue to stay abreast with developments and newer drugs that may help modify the outcome. The team dynamics have also become more complex, which necessitates the need for all care providers (surgeons, cardiologists, anesthesiologists, and intensivists to better understand the interactions and benefits of newer drugs. Vasopressin has been used in our adult patients for more than a decade and recently has found its rightful place in the pediatric armoury.

  14. MR-guided cardiac catheterization

    International Nuclear Information System (INIS)

    Exposing young children to X-rays is a source of concern, since the effect is cumulative and it is important to avoid adding to their lifetime dose. This becomes particularly significant in the case of congenital heart disease, as the patients often need life-long monitoring and successive interventions. Alternative imaging techniques are needed in order to eliminate or limit X-ray exposure. This article demonstrates the feasibility of MR-guided cardiac catheterization using passive device visualization. The procedures are performed in a Philips XMR suite, where all or a substantial part of the catheterization procedure is performed with MR guidance, resulting in significant dose savings. (orig.)

    Abstract Children who underwent surgery for complex congenital heart defects present worse exercise capacity than their healthy peers. In adults and adolescents, heart failure is assessed on the basis of clinical symptoms using the New York Heart Association (NYHA) score, while in an infant Ross scale; heart failure can also be evaluated by other parameters. The purpose of this study was to compare the degree of exercise tolerance in children after surgery for complex heart defects, assessed by the ratio of maximum oxygen uptake (VO2max) and the brain natriuretic peptide (N-terminal fragment of the prohormone brain-type natriuretic peptide [NT-proBNP]) concentration. The study group consisted of 42 children, ages 9 to 17 years (mean 14.00 ± 2.72). Among them there were 22 children with tetralogy of Fallot (ToF) after total correction, 18 children with transposition of the great arteries (d-TGA) after the arterial switch operation, and 2 children with single ventricle (SV) after the Fontan operation. All but 1 child were in NYHA class I. The control group consisted of 20 healthy children. Outcomes of interest were the ratio of VO2max, determined during ergospirometry, and the level of NT-proBNP. The statistical analysis was performed and the groups were considered significantly different for P < 0.05. There was no statistically significant correlation between NT-proBNP and maximum oxygen uptake (VO2) kg−1 min−1 in the study group compared with the control group. The VO2max in the test group had a mean value less (34.6 ± 8.0) than controls (38.4 ± 7.7), and the differences were statistically significant (P = 0.041). In contrast, the average concentration of NT-proBNP in the study group was higher than controls (117.9 ± 74.3 vs 18.0 ± 24.5), and these differences were statistically significant (P < 0.001). After operations for complex heart defects (ToF, TGA, and SV), children have worse heart function parameters and exercise

    Full Text Available Objective: to describe the knowledge and significance of cardiac catheterization from cardiac patients’ perspective. Methods: descriptive and qualitative study of patients undergoing cardiac catheterization. Five categories were identified through content analysis. Results: knowledge of patients on cardiac catheterization proved to be limited; the subject was surrounded by lack of knowledge. Cardiac catheterization means a treatment for unblocking coronary arteries and it is confused with therapeutic purposes. There were reports of symptoms related to heart disease such as fatigue and chest pain and related to the exams such as worry, anxiety, depression, fear and restlessness generated, mainly, by expectations of the unknown. The majority of the respondents proved to be satisfied with the results of the exam, due to the discovery and treatment of heart diseases. Conclusion: cardiac catheterization means treatment and clearance of coronary arteries and it is confused with therapeutic purposes. Feelings such as worry, anxiety, fear and restlessness are described when patients are subjected to examination, generated mainly by expectations of the unknown.

    Although the utility of diagnostic cardiac catheterization in the clinical setting has diminished over the last years, due to the emergence of noninvasive imaging modalities, such as echocardiography, magnetic resonance imaging and computed tomography, catheterization for diagnostic reasons still constitutes a valuable tool in certain parts in the workup of pediatric heart disease. As a result, awareness of the main aspects of diagnostic catheterization is of great importance for the clinical cardiologist. In this article, the main variables measured and the main actions performed during diagnostic cardiac catheterization in children are discussed. PMID:26926292

  4. Stimulating endogenous cardiac regeneration

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

    Full Text Available Introduction. Despite remarkable advances in medicine and sports, sudden cardiac death remains a significant problem. Incidence of sudden cardiac death. The incidence of sudden cardiac death varies in different studies and there are no systematic data about it. It varies in different types of sports, with age and sex. Sudden cardiac death and physical activity. Many changes in cardiac morphology and function represent an adaptive response to physical activity. As a result, the heart undergoes profound morphologic, functional and electro-physiological alterations. But as there are different kinds of physical activities, the degree of these morphological changes is highly variable. It is needless to say how important it is to know which changes in the heart due to physical activity are normal, and when they are pathological. Considering the results of many studies, the main cause of sudden cardiac death is hypertrophic cardiomiopathy. Conclusion. It is very important to distinguish physiological changes of the heart due to physical activity, and pathological changes due to some cardiac diseases. That is why, clear recommendations on intensity, type, duration and frequency of physical training in every sports discipline are necessary. That is the only way to decrease the incidence of sudden cardiac death in athletes. .

    Previous studies showed that decreased cerebral saturation during cardiac surgery is related to adverse postoperative outcome. Therefore, we investigated the influence of intraoperative events on cerebral tissue saturation in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). A total of 52 adult patients who underwent cardiac surgery using pulsatile CPB were included in this prospective explorative study. Cerebral tissue oxygen saturation (SctO2) was measured in both the left and right cerebral hemisphere. Intraoperative events, involving interventions performed by anesthesiologist, surgeon, and clinical perfusionist, were documented. Simultaneously, in-line hemodynamic parameters (partial oxygen pressure, partial carbon dioxide pressure, hematocrit, arterial blood pressure, and CPB flow rates) were recorded. Cerebral tissue saturation was affected by anesthetic induction (p partial oxygen pressures changed. Cerebral tissue oximetry effectively identifies changes related to surgical events or vulnerable periods during cardiac surgery. Future studies are needed to identify methods of mitigating periods of reduced cerebral saturation. PMID:26390677

    Currently, effective pharmacologic treatment to reduce severe oral mucositis (OM) resulting from high-dose myeloablative cytotoxic therapy in the pediatric population is not available. Palifermin has been proven to decrease the incidence and duration of severe OM in adults with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT). In the pediatric population, however, data on palifermin treatment are limited. A phase I dose-escalation study of palifermin in pediatric patients with acute leukemias undergoing myeloablative HSCT with total body irradiation, etoposide, and cyclophosphamide was performed to determine a safe and tolerable dose and to characterize the pharmacokinetic (PK) profile and efficacy of palifermin. Twenty-seven patients in 3 age groups (1 to 2, 3 to 11, and 12 to 16 years) and 3 dose levels (40, 60, and 80 μg/kg/day) were studied. There were no deaths, dose-limiting toxicities, or treatment-related serious adverse events. Long-term safety outcomes did not differ from what would be expected in this population. PK data showed no differences between the 3 age groups. Exposure did not increase with increase in dose. The maximum severity of OM (WHO grade 4) occurred in 6 patients (22%), none of whom was in the 80-μg/kg/day dosing group. This study showed that all doses were well tolerated and a good safety profile in all 3 pediatric age groups was seen. PMID:26968792

    As we age, our hearts undergo changes which result in reduction in complexity of physiological interactions between different control mechanisms. This results in a potential risk of cardiovascular diseases which are the number one cause of death globally. Since cardiac signals are nonstationary and nonlinear in nature, complexity measures are better suited to handle such data. In this study, non-invasive methods for detection of cardiac aging using complexity measures are explored. Lempel-Ziv (LZ) complexity, Approximate Entropy (ApEn) and Effort-to-Compress (ETC) measures are used to differentiate between healthy young and old subjects using heartbeat interval data. We show that both LZ and ETC complexity measures are able to differentiate between young and old subjects with only 10 data samples while ApEn requires at least 15 data samples.

    Blunt injury to the heart ranges from contusion to disruption. This report comprises 14 patients seen during a 6-year period with cardiac rupture secondary to blunt trauma. Eight patients were injured in automobile accidents, two patients were injured in auto-pedestrian accidents, two were kicked in the chest by ungulates, and two sustained falls. Cardiac tamponade was suspected in ten patients. Five patients presented with prehospital cardiac arrest or arrested shortly after arrival. All underwent emergency department thoracotomy without survival. Two patients expired in the operating room during attempted cardiac repair; both had significant extracardiac injury. Seven patients survived, three had right atrial injuries, three had right ventricular injuries, and one had a left atrial injury. Cardiopulmonary bypass was not required for repair of the surviving patients. There were no significant complications from the cardiac repair. The history of significant force dispersed over a relatively small area of the precordium as in a kicking injury from an animal or steering wheel impact should alert the physician to possible cardiac rupture. Cardiac rupture should be considered in patients who present with signs of cardiac tamponade or persistent thoracic bleeding after blunt trauma. PMID:6708151

  19. DNA methylation in cardiac fibrosis: New advances and perspectives

    International Nuclear Information System (INIS)

    Cardiac fibrosis is characterized by net accumulation of extracellular matrix (ECM) proteins in the cardiac interstitium, and contributes to both systolic and diastolic dysfunction in many cardiac pathophysiologic conditions. More specifically, cardiac fibroblasts are activated by a variety of pathological stimuli, thereby undergoing proliferation, differentiation to myofibroblasts, and production of various cytokines and ECM proteins. Thus, understanding the biological processes of cardiac fibroblasts will provide novel insights into the underlying mechanisms of cardiac fibrosis. DNA methylation is an important epigenetic mechanism, which often occurs in response to environmental stimuli and is crucial in regulating gene expression. The aberrant methylation of CpG island promoters of selected genes is the prominent epigenetic mechanism by which gene transcription can be effectively silenced. Aberrant hypermethylation of a few selected genes such as RASSF1A plays an important role in facilitating fibrotic fibroblast activation and in driving fibrosis. In this review we will discuss the mechanisms of DNA methylation and their implications for cardiac fibroblasts activation and fibrosis. Control of DNA methylation may serve as a new strategy for anti-fibrotic therapy

    Before non-cardiac surgery, evaluation of cardiac function is no frequent part of surgical treatment. European societies of anesthesiology and cardiology published consensus-guidelines in 2014 to present a reasonable approach for preoperative evaluation. This paper intends to differentiate the composite of perioperative risk and to display the guidelines methodical approach to handle it. Features to identify patients at risk from an ageing population with comorbidities, are the classification of surgical risk, functional capacity and risk indices. Application of diagnostic means, should be used adjusted to this risk estimation. Cardiac biomarkers are useful to discover risk of complications or mortality, that cannot be assessed by clinical signs. After preoperative optimization and perioperative cardiac protection, the observation of the postoperative period remains, to prohibit complications or even death. In consideration of limited resources of intensive care department, postoperative ward rounds beyond intensive care units are considered to be an appropriate instrument to avoid or recognize complications early to reduce postoperative mortality.

    Sri Lanka is an island nation in Indian Ocean that provides free healthcare to all citizens through government healthcare system. It has commendable health indices in the region. Pediatric cardiac services have rapidly progressed over past few years helping to further bring down infant and under-five mortality rates. Lady Ridgeway Hospital for Children (LRH) is the only tertiary care referral center for children with heart disease in the country. Currently it performs approximately 1,000 cardiac catheterizations and 1,000 cardiac surgeries every year. Target is to double the surgical output to treat all children with heart diseases in a timely and appropriate manner. Being a middle-income country, this is not an easy task. Technology used in diagnosis and treatment of congenital heart diseases is rapidly advancing with its price tag. In such a setting, it is challenging to proceed to achieve this target in a resource-limited environment. PMID:26085764

    To evaluate automated segmentation and the effects of different manual adjustments regarding left ventricular parameter quantification in cardiac magnetic resonance (MR) data on children and adolescents who have undergone surgical repair of right-sided congenital heart disease (CHD). Dedicated software (syngo.via, Siemens AG) was used to automatically segment and/or manually adjust the end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), myocardial mass (MM) and ejection fraction (EF) before/after manual apex/base adjustment (ADJ-step 1) and after manual apex/base/myocardial contour adjustment (ADJ-step 2; reference standard). MR data of 40 patients (13.1 ± 3.1y, 4-17y) with repaired CHD with decreased pulmonary blood flow (CHD-DPBF) were evaluated. Intra- and inter-rater reliability was determined for 10 randomly selected patients. The software correctly detected the left ventricle in 38/40 (95 %) patients. EDV after automated segmentation: 119.1 ± 44.0ml; after ADJ-step 1: 115.8 ± 39.5 ml; after ADJ-step 2: 116.2 ± 39.4 ml. The corresponding results for ESV were 52.0 ± 18.5/49.6 ± 16.9/49.7 ± 16.4 ml; for SV 67.1 ± 28.5/66.2 ± 25.4/66.5 ± 25.5 ml; for EF 55.5 ± 7.3/56.7 ± 6.6/56.7 ± 6.3%; for MM 83.7 ± 35.9/76.2 ± 28.3/74.6 ± 27.2 g. Significant differences were found for ESV/MM/EF comparing the automated segmentation results with these after ADJ-step 1 and ADJ-step 2. No significant differences were found when comparing all results of ADJ-step 1 and ADJ-step 2 or when comparing EDV/SV results. Intra- and inter-rater reliability was excellent. The mean time effort was 63.4 ± 6.9 s for the automated segmentation, 74.2 ± 8.9 s for ADJ-step 1 and 269.5 ± 39.4 s for ADJ-step 2. Automated left ventricular volumes and function analysis in children and adolescents with surgically treated CHD proved to be feasible with excellent intra- and inter-rater reliability.

    The goals of cardiac rehabilitation are (re-)conditioning and secondary prevention in patients with heart disease or an elevated cardiovascular risk profile. Rehabilitation is based on motivation through education, on adapted physical activity, instruction of relaxation techniques, psychological support and optimized medication. It is performed preferably in groups either in outpatient or inpatient settings. The Swiss working group on cardiac rehabilitation provides a network of institutions with regular quality auditing. Positive effects of rehabilitation programs on mortality and morbidity have been established by numerous studies. Although a majority of patients after cardiac surgery are being referred to rehabilitation, these services are notoriously underused after catheter procedures. PMID:26602848

    Full Text Available Cardiac tumors are rare, and of these, primary cardiac tumors are even rarer. Metastatic cardiac tumors are about 100 times more common than the primary tumors. About 90% of primary cardiac tumors are benign, and of these the most common are cardiac myxomas. Approximately 12% of primary cardiac tumors are completely asymptomatic while others present with one or more signs and symptoms of the classical triad of hemodynamic changes due to intracardiac obstruction, embolism and nonspecific constitutional symptoms. Echocardiography is highly sensitive and specific in detecting cardiac tumors. Other helpful investigations are chest X-rays, magnetic resonance imaging and computerized tomography scan. Surgical excision is the treatment of choice for primary cardiac tumors and is usually associated with a good prognosis. This review article will focus on the general features of benign cardiac tumors with an emphasis on cardiac myxomas and their molecular basis.

    Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.

An athlete's death draws high public attention given that athletes are considered the healthiest category of society. The vast majority of sudden cardiac death in young athletes is due to congenital cardiac malformations such as hypertrophie cardiomyopathy and various coronary artery anomalies. In athletes over age 35, the usual cause of sudden cardiac death is coronary artery disease. With each tragic death of a young athlete, there is a question why this tragedy has not been prevented. The American College of Sports Medicine and the American Heart Association recommend that a pre-participation exam should include a complete cardiovascular history and physical examination.

    The purpose of this review is to give an overview of the rehabilitation measures provided for cardiac patients in Germany and to outline its legal basis and outcomes. In Germany the cardiac rehabilitation system is different from rehabilitation measures in other European countries. Cardiac rehabilitation in Germany since 1885 is based on specific laws and the regulations of insurance providers. Cardiac rehabilitation has predominantly been offered as an inpatient service, but has recently been complemented by outpatient services. A general agreement on the different indications for offering these two services has yet to be reached. Cardiac rehabilitation is mainly offered after an acute cardiac event and bypass surgery. It is also indicated in severe heart failure and special cases of percutaneous coronary intervention. Most patients are men (>65%) and the age at which events occur is increasing. The benefits obtained during the 3-4 weeks after an acute event, and confirmed in numerous studies, are often later lost under 'usual care' conditions. Many attempts have been made by rehabilitation institutions to improve this deficit by providing intensive aftercare. One instrument set up to achieve this is the nationwide institution currently comprising more than 6000 heart groups with approximately 120000 outpatients. After coronary artery bypass grafting or acute coronary syndrome cardiac rehabilitation can usually be started within 10 days. The multidisciplinary rehabilitation team consists of cardiologists, psychologists, exercise therapists, social workers, nutritionists and nurses. The positive effects of cardiac rehabilitation are also important economically, for example, for the improvement of secondary prevention and vocational integration. PMID:17301623

    Ranolazine utilization in the management of refractory angina has been established by multiple randomized clinical studies. However, there is growing evidence showing an evolving role in the field of cardiac arrhythmias. Multiple experimental and clinical studies have evaluated the role of ranolazine in prevention and management of atrial fibrillation, with ongoing studies on its role in ventricular arrhythmias. In this review, we will discuss the pharmacological, experimental, and clinical evidence behind ranolazine use in the management of various cardiac arrhythmias. PMID:26459200

    Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspect...

    Full Text Available Long procedure time and somewhat suboptimal results hinder the widespread use of catheter ablation of complex arrhythmias such as atrial fibrillation (AF. Due to lack of contrast differentiation between the area of interest and surrounding structures in a moving organ like heart, there is a lack of proper intraprocedural guidance using current imaging techniques for ablation. Cardiac image registration is currently under investigation and is in clinical use for AF ablation. Cardiac image registration, which involves integration of two images in the context of left atrium (LA, is intermodal, with the acquired image and the real-time reference image residing in different image spaces, and involves optimization, where one image space is transformed into the other. Unlike rigid body registration, cardiac image registration is unique and challenging due to cardiac motion during the cardiac cycle and due to respiration. This review addresses the basic principles of the emerging technique of registration and the inherent limitations as they relate to cardiac imaging and registration.

  10. Patient doses in digital cardiac imaging

    International Nuclear Information System (INIS)

    In this pilot study, we obtained estimates of entrance skin doses and the corresponding effective doses to patients undergoing digital cardiac imaging procedures on a GE Advantx LC/LP Plus system. Data were obtained for six patients undergoing diagnostic examinations and six patients who had interventional procedures. For each patient examination, radiographic techniques for fluoroscopic and digital cine imaging were recorded, together with the irradiation geometry. The projection with the highest exposure resulted in an average skin dose of 0.64 ± 0.41 Gy (maximum of 1.6 Gy). The average patient skin doses taking into account overlapping projections was 1.1 ± 0.8 Gy (maximum of 3.0 Gy). The exposure area product (EAP) incident on the patient was converted into the energy imparted to the patient and the corresponding effective dose. The average patient effective dose was 28 ± 14 mSv (maximum 62 mSv), with the resultant average fatal cancer risk estimated to be of the order of 8x10-3 . Average doses for interventional procedures in cardiac imaging are higher than those associated with diagnostic examinations by approximately 50%. (author)

    Background The LaFarge equation is the most commonly used equation to estimate oxygen consumption (Vo2) in patients of all ages with congenital heart disease, although it was generated in patients older than 3 years. We sought to determine the validity of the LaFarge equation in estimating Vo2 in children younger than 3 years undergoing cardiac catheterization with general anesthesia. Methods Vo2 was measured directly using respiratory mass spectrometry in 75 sedated, paralyzed, and mechanically ventilated children in the pediatric cardiac catheterization laboratory. Age ranged from 0.13 to 24 years; 40 children being younger than 3 years. Estimated values for Vo2 were calculated using the LaFarge equation for all patients. The agreement between measured and estimated Vo2 was evaluated by the bias and limits of agreement in the 2 age groups. Regression analysis was used to analyze the influence of age on the agreement. Results A failure of agreement between measured and estimated Vo2 was noted in both groups of children. As compared to the older group of patients, the agreement was significantly poorer in children younger than 3 years, with a significantly greater overestimation introduced by the LaFarge equation (11% ± 21% vs 53% ± 52%, P LaFarge equation introduces significant error in the estimation of Vo2 in ventilated patients with congenital heart disease of all ages, particularly in children younger than 3 years.

  2. Benefits of quantitative gated SPECT in evaluation of perioperative cardiac risk in noncardiac surgery

    International Nuclear Information System (INIS)

    Gated single-photon emission computed tomography (G-SPECT) was used to evaluate cardiac risk associated with noncardiac surgery and determine the benefits and indications of this technique for this type of surgery. Patients scheduled to undergo noncardiac surgery under the supervision of anesthesiologists and subjected to preoperative cardiac evaluation using G-SPECT during the 26-month period between June 2000 and August 2002 were followed for the presence/absence of cardiac events (id est (i.e.), cardiac death, myocardial infarction, unstable angina, congestive heart failure, or fatal arrhythmia) during surgery and the postoperative period until discharged. Relationships between the occurrence of cardiac events and preoperative G-SPECT findings were evaluated. A total of 39 patients underwent G-SPECT; 6 of the 39 exhibited abnormal ejection fraction (left ventricular ejection fraction, left ventricular ejection fraction (LVEF)≤50%) and end-systolic volume (end-systolic volume (ESV)≥50 ml). Surgery was suspended for three of these six patients and cardiac events developed in the remaining three patients. Both abnormal perfusion images (PI) and abnormal wall thickening (WT) were observed in all six patients. All six patients exhibited abnormal LVEF and/or ESV. Three patients had either abnormal PI or WT, and a cardiac event occurred in one of them. Of the five patients who experienced cardiac events during or after surgery, two exhibited a short run of ventricular tachycardia requiring a continuous administering of antiarrhythmic drugs, whereas the remaining three patients exhibited cardiac failure requiring inotropic support following surgery. The results of this study indicate that the occurrence of perioperative cardiac events can be predicted by considering the severity of expected surgical stress and preoperative G-SPECT findings for LVEF, PI, and WT. We conclude that G-SPECT is quite useful for cardiac risk assessment in patients undergoing noncardiac

    Full Text Available Introduction: Primary cardiac tumors are extremely rare in infants and children . Most primary cardiac tumors in pediatric age group are benign, and less than 10% of such tumors are malignant. Many of these tumors are asymptomatic and incidentally diagnosed. The clinical manifestations are very different and includes direct cardiac effect, systemic effect , and embolic phenomena. Every infant or child with an unusual cardiac murmur, unexplained congestive heart failure, or arrhythmia should be evaluated for cardiac tumors. Echocardiography has contributed significantly to the evaluation of these patients. Surgery is the only treatment for primary cardiac tumors that require intervention with a relatively good prognosis. Case Report: The patient was a 20 days old neonate presented with severe congestive heart failure. Evaluation of the patient showed primary cardiac tumor in the left atrium and ventricle. We recommended surgical removal of the tumor but her parents denied surgical intervention at all. Conclusion: After about one year follow up, congestive heart failure symptoms were controlled and the tumor size was decreased.

    It is well recognized that poor perioperative blood glucose (BG) control can increase the risk of infection, cardiovascular accidents, and even death in patients undergoing cardiac surgery. Since it has been reported that tight BG control (80-110 mg/dL) yields better outcomes in critically ill patients, it became a standard of care to control BG using intravenous insulin infusion in ICU. However, it has been debated in terms of the optimal target range whether a strict control with intensive ...

    2007-01-01

    Following an electrical stimulus, the transmembrane voltage of cardiac tissue rises rapidly and remains at a constant value before returning to the resting value, a phenomenon known as an action potential. When the pacing rate of a periodic train of stimuli is increased above a critical value, the action potential undergoes a period-doubling bifurcation, where the resulting alternation of the action potential duration is known as alternans in the medical literature. Existing cardiac models treat alternans either as a smooth or as a border-collision bifurcation. However, recent experiments in paced cardiac tissue reveal that the bifurcation to alternans exhibits hybrid smooth/nonsmooth behaviors, which can be qualitatively described by a model of so-called unfolded border-collision bifurcation. In this paper, we obtain analytical solutions of the unfolded border-collision model and use it to explore the crossover between smooth and nonsmooth behaviors. Our analysis shows that the hybrid smooth/nonsmooth behavi...

    Full Text Available Operating room fires are rare events, but when occur they result in serious and sometimes fatal consequences. Anaesthesia ventilator fire leading to cardiac arrest is a rare incident and has not been reported. We report a near catastrophic ventilator fire leading to cardiac arrest in a patient undergoing subtotal thyroidectomy. In the present case sparks due to friction or electrical short circuit within the ventilator might have acted as source of ignition leading to fire and explosion in the oxygen rich environment. The patient was successfully resuscitated and revived with uneventful recovery and no adverse sequelae. The cardiac arrest was possibly due to severe hypoxia resulting from inhalation of smoke containing high concentrations of carbon monoxide and other noxious gases.

CT and MR images showed good agreement: LV EF (Ejection Fraction) (52 {+-} 14% for CT vs. 52 {+-} 14% for MR; r = 0.73; p > 0.05); RV EF (47 {+-} 12% for CT vs. 47 {+-} 12% for MR; r = 0.74; p > 0.05); LV EDV (End Diastolic Volume) (74 {+-} 21 ml/m{sup 2} for CT vs. 76 {+-} 25 ml/m{sup 2} for MR; r = 0.59; p > 0.05); RV EDV (84 {+-} 25 ml/m{sup 2} for CT vs. 80 {+-} 23 ml/m{sup 2} for MR; r = 0.58; p > 0.05); LV ESV (End Systolic Volume)(37 {+-} 19 ml/m{sup 2} for CT vs. 38 {+-} 23 ml/m{sup 2} for MR; r = 0.76; p > 0.05); RV ESV (46 {+-} 21 ml/m{sup 2} for CT vs. 43 {+-} 18 ml/m{sup 2} for MR; r = 0.70; p > 0.05). Intra- and inter-observer variability were good, and the performance of CT was maintained for different EF subgroups. Cardiac CT provides accurate and reproducible LV and RV volume parameters compared with MR, and can be considered as a reliable alternative for patients who are not suitable to undergo MR. circle Cardiac-CT is able to provide Left and Right Ventricular function. circle Cardiac-CT is accurate as MR for LV and RV volume assessment.

  16. Evolutionary origin of cardiac malformations.

    Taussig, H B

    1988-10-01

    The author has proposed in previous publications that isolated cardiac malformations have an evolutionary origin. This is partly supported by the fact that isolated cardiac malformations found in humans occur also in other placental mammals as well as in birds. External gross examination of the heart in just over 5,000 birds was carried out during a 3 year period. Anomalies included one instance of duplicate hearts, two specimens in which no heart could be identified and in a fourth, a yellow-rumped warbler, the heart lay in the neck outside of the thoracic cavity. Published reports of similar occurrences of an ectopically placed heart concern birds, cattle and humans. The fact that various species of both placental mammals and birds show evidence of heritability for heart defects, and that these species cannot interbreed, combined with the fact that birds and mammals have many similar malformations, points to either a common external causative factor or a common origin. Genes that code the malformed heart must be transmitted with that part of the genetic makeup common to all birds and mammals. Malformations caused by teratogens produce widespread organ injury to a potentially normal embryo whereas the evolutionary malformation is an organ-specific anomaly in an otherwise normal mammal or bird and occurs in widely separated species. The implications of this theory are important for parents of children with an isolated congenital heart defect who may have ingested one or another drug or chemical or have been exposed to toxins or infectious agents before or after conception of the affected offspring.

    Introduction Exercise training, besides many health benefits, may result in cardiac remodelling which is dependent on the type and amount of exercise performed. It is not clear, however, whether significant adaptation in cardiac structure is possible in females undergoing resistance type of exercise training. Rigorous high volume training of most muscle groups emphasising resistance exercises are being undertaken by athletes of some aesthetic sports such as female fitness (light bodybuilding). The impact of this type of training on cardiac adaptation has not been investigated until now. The aim of the current study was to disclose the effect of high volume resistance training on cardiac structure and function. Methods 11 top-level female fitness athletes and 20 sedentary age-matched controls were recruited to undergo two-dimensional echocardiography. Results Cardiac structure did not differ between elite female fitness athletes and controls (p > 0.05), and fitness athletes had a tendency for a smaller (p = 0.07) left ventricular (LV) mass indexed to lean body mass. Doppler diastolic function index (E/A ratio) and LV ejection fraction were similar between the groups (p > 0.05). Conclusions Elite female fitness athletes have normal cardiac size and function that do not differ from matched sedentary controls. Consequently, as high volume resistance training has no easily observable effect on adaptation of cardiac structure, when cardiac hypertrophy is present in young resistance-trained lean female, other reasons such as inherited cardiac disease are to be considered carefully.

  18. Radiography in cardiology [cardiac disorders, cardiac insufficiency

    International Nuclear Information System (INIS)

    The diagnostic procedure in cardiology nearly always requires an X-ray examination of the thorax. This examination is very informative when it is correctly performed and interpreted. The radiographs need to be read precisely and comprehensively: this includes the evaluation of the silhouette of the heart (size, form and position) as well as the examination of extra-cardiac thoracic structures allowing among other things to search for signs of cardiac insufficiency. The conclusion of the X-ray examination can be drawn after having brought together information concerning the case history, the clinical examination and the study of the radiographs. The radiologist finds himself in one of three situations: (1) the information provided by the X-ray pictures is characteristic of a disease and permits a diagnosis, (2) the X-ray pictures indicate a group of hypotheses; further complementary tests could be useful and (3) the X-ray pictures provide ambiguous even contradictory information; it is necessary to complete the radiological examination by other techniques such as an ultrasonographic study of the heart

    Gynecologists frequently seek the opinion of a psychiatrist before performing tubal ligations. The case of a 25-year-old childless divorcee whose gynecologist feared that her request for sterilization was actually a sign of depression is described to illustrate different aspects of psychiatric evaluation of women seeking sterilization. The patient's appearance and comportment during the interview, husband, family, attitude toward children, and dreams appeared normal. A traditional psychiatric evaluation shed little light on her reasons for seeking sterilization. A scale developed in the course of a few years of interviewing sterilization candidates to try to achieve a degree of objectivity was applied to the case. The scale requires assessment of the client's motivation, contraceptive usage, self-image, psychosexual development, the economic value of the ligation, and the consequences for the patient's sexual, social, and professional life. The psychiatrist summarizes his detailed findings and states them in comprehensible and practical terms for the sterilization practitioner. In this case, the client was raised rather coldly in a large family of 13 children where she received little attention from her father or mother. Her family background caused her to enter the work force at a very early age and to seek affection from an older man whom she married at 19 after 2 years of living together. She soon realized that he could not fill her need for affection and decided to leave him as he was demanding a child. Her 2nd partner was an alcoholic whom she left for the same reasons. She could not accept the idea of having a child who would be demanding when her own needs were so pressing. Her position was reinforced by her belief that she could not use oral contraceptives because of recurrent infections and that the IUD is unreliable. Deep psychotherapy could probably lower her resistence to motherhood but the client had no motivation for it. There was little reason not to

    There are currently in North America more adults with congenital heart disease than children. This article discusses the anesthetic considerations in adults with single-ventricle physiology and prior repairs who present for Fontan conversion surgery as a demonstration of the challenges of caring for adults undergoing interventions for the repair of congenital heart defects. The care of these patients requires an understanding of the impact of passive pulmonary blood flow and single systemic ventricular physiology. The perioperative morbidity in this patient population remains high. PMID:23711650

    . Cardiac amyloidosis is often under diagnosed due to unspecific and varied signs and symptoms. The diagnosis is confirmed by endomyocardial biopsy, an invasive procedure with inherent risks to this technique. Pyrophosphate-{sup 99m}Tc scintigraphy is a simple, non-invasive, low cost, with good sensitivity method for detection of cardiac amyloidosis. The scintigraphy pattern observed in cardiac amyloidosis cases is abnormal diffuse tracer uptake in both heart ventricles. Planar and/or tomographic imaging may be performed. It is considered a highly sensitive test, with low rates of false-negative results despite the existing little literature. Therefore the scintigraphy can be useful to select patients for biopsy. Conclusion: Scintigraphy can be of great assistance in cardiac amyloidosis, despite its low specificity. Due to its high sensibility, it can be a useful test to early discriminate patients who should undergo biopsy, allowing treatment optimization. (author)

    Understanding the mutual relationship between the liver and the heart is important for both hepatologists and cardiologists. Hepato-cardiac diseases can be classified into heart diseases affecting the liver, liver diseases affecting the heart, and conditions affecting the heart and the liver at the same time. Differential diagnoses of liver injury are extremely important in a cardiologist’s clinical practice calling for collaboration between cardiologists and hepatologists due to the many other diseases that can affect the liver and mimic haemodynamic injury. Acute and chronic heart failure may lead to acute ischemic hepatitis or chronic congestive hepatopathy. Treatment in these cases should be directed to the primary heart disease. In patients with advanced liver disease, cirrhotic cardiomyopathy may develop including hemodynamic changes, diastolic and systolic dysfunctions, reduced cardiac performance and electrophysiological abnormalities. Cardiac evaluation is important for patients with liver diseases especially before and after liver transplantation. Liver transplantation may lead to the improvement of all cardiac changes and the reversal of cirrhotic cardiomyopathy. There are systemic diseases that may affect both the liver and the heart concomitantly including congenital, metabolic and inflammatory diseases as well as alcoholism. This review highlights these hepatocardiac diseases

  6. Primary cardiac tumors

    International Nuclear Information System (INIS)

    Cardiac tumors happen to be among the less known pathologies without clear treatment standards. Even one decade ago most of the cardiac tumor diagnosis were made post mortem, and only reports of isolated cases could be found in the literature, showing the lack of interest in the investigation of these pathologies by cardiology and cardiovascular surgery specialists. With the development of echocardiography and of cardiovascular surgery, more cases of primary and metastatic cardiac tumors have been diagnosed. Many cases have been treated by palliative or curative surgical interventions, thus increasing the reports in the world literature and the experience in this field, and pointing out the real incidence of these pathologies, not being as bizarre as it had been considered. a revision of the literature will be made, in which the frequency and the suggested interventions will be reported, as well as the cases of cardiac pathology in two cardiovascular centers of the country known by the author. The echocardiographic, pathologic and histological characteristics of the representative cases will be presented, without a greater evidence level, due to the problem's incidence and the few cases reported by these centers

    International Nuclear Information System (INIS)

    Cardiac MRI tagging is an original technique based upon the perturbation of the magnetization of determined regions of the myocardium (tags). The motion of the tags accurately reflects the deformation of the underlying tissue. Data analysis requires special techniques to reconstruct the 3D motion of the heart, and to evaluate the myocardial strain, locally and throughout the whole heart. (authors)

    2014-07-01

    Vasopressin is an essential hormone involved in the maintenance of cardiovascular homeostasis. It has been in use therapeutically for many decades, with an emphasis on its vasoconstrictive and antidiuretic properties. However, this hormone has a ubiquitous influence and has specific effects on the heart. Although difficult to separate from its powerful vascular effects in the clinical setting, a better understanding of vasopressin's direct cardiac effects could lead to its more effective clinical use for a variety of shock states by maximizing its therapeutic benefit. The cardiac-specific effects of vasopressin are complex and require further elucidation. Complicating our understanding include the various receptors and secondary messengers involved in vasopressin's effects, which may lead to various results based on differing doses and varying environmental conditions. Thus, there have been contradictory reports on vasopressin's action on the coronary vasculature and on its effect on inotropy. However, beneficial results have been found and warrant further study to expand the potential therapeutic role of vasopressin. This review outlines the effect of vasopressin on the coronary vasculature, cardiac contractility, and on hypertrophy and cardioprotection. These cardiac-specific effects of vasopressin represent an interesting area for further study for potentially important therapeutic benefits. PMID:24621650

    2013-01-01

    Full Text Available Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552. Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

    Cardiac amyloidosis, most often of AL type, is a non-exceptional disease as it represents 5 to 10% of non-ischemic cardiomyopathies. It realizes typically a restrictive cardiomyopathy. Nevertheless the wide diversity of possible presentation makes it a "big shammer" which must be evoked in front of every unexplained cardiopathy after the age of forty. If some associated manifestations can rapidly suggest the diagnosis, as a peripheric neuropathy especially a carpal tunnel syndrome or palpebral ecchymosis, cardiac involvement can also evolve in an apparently isolated way. The most suggestive paraclinic elements for the diagnosis are, in one hand, the increased myocardial echogenicity with a "granular sparkling" appearance seen throughout all walls of the left ventricle and, in the other hand, the association of a thickened left ventricle and a low voltage (electrocardiogram could also show pseudo-infarct Q waves). In front of such aspects, the proof of amyloidosis is brought by an extra-cardiac biopsy or by scintigraphy with labelled serum amyloid P component, so that the indications of endomyocardial biopsy are very limited today. The identification of the amyloid nature of a cardiopathy has an direct therapeutic implication: it contra-indicates the use of digitalis, calcium channel blockers and beta-blockers. The treatment of AL amyloidosis (chemotherapy with alkylant agents) remains very unsatisfactory especially in the cardiac involvement which is the most frequent cause of death (in AL amyloidosis). Last, cardiac amyloidosis is a bad indication for transplantation which results are burden by rapid progression of deposits especially in the gastro-intestinal tract and the nervous system.

    Accrediting organizations and payers are demanding valid and reliable data that demonstrate the value of services. Federal agencies, healthcare industry groups, and healthcare watchdog groups are increasing the demand for public access to outcomes data. A new and growing outcomes dynamic is the information requested by prospective patients in an increasingly consumer-oriented business. Patients demand outcomes, and resources are developing to meet these demands. Physicians are increasingly confronted with requests for information about their mortality and morbidity rates, malpractice suits, and disciplinary actions received. For example, in Virginia, prospective patients have access to data provided by the nonprofit group Virginia Health Information. After numerous resolutions by the Virginia Senate since 1999, the prospective Virginia medical consumer now has access to several annual publications: Virginia Hospitals: A Consumer's Guide, 1999 Annual Report and Strategic Plan Update, and the 1999 Industry Report: Virginia Hospitals and Nursing Facilities. Consumers have access to cardiac outcomes data stratified by hospital, gender, and cardiac service line (cardiac surgery, noninvasive cardiology, and invasive cardiology). This is particularly relevant to IHI because Virginia Health Information specifically targets cardiac care. IHI has a sizable investment in cardiovascular outcomes and has found outcomes measurement and research are key to providing quality care. IHI's goal is to move from an outcomes management model to a disease management model. The hope is to incorporate all aspects of the patient's continuum of care, from preoperative and diagnostic services through cardiac interventions to postoperative rehabilitation. Furthermore, every step along the way will be supported with functional status and quality of life assessments. Although these goals are ambitious and expensive, the return on investment is high.

    Full Text Available Background: Coagulopathy is a major issue in children undergoing high-risk pediatric cardiac surgery. Use of anti-fibrinolytics is well documented in adults, but recently there are questions raised about safety and effectiveness of their use on routine use. Tranexamic acid is a potent anti-fibrinolytic, but its role is not fully understood in children. This study aims to study the benefits tranexamic acid in controlling postoperative bleeding in pediatric cardiac surgical patients. Methods and Results: Fifty consecutive children who underwent cardiac surgery were randomized prospectively to receive either aprotinin (Group A; n = 24 or tranexamic acid (Group B; n = 26 from September 2009 to February 2010 were studied. Primary end points were early mortality, postoperative drainage, reoperation for bleeding and complications. Mean age and body weight was smaller in Group A (Age: 48.55 vs. 64.73 months; weight 10.75 vs. 14.80 kg respectively. Group A had more cyanotic heart disease than Group B (87.5% vs. 76.92%. Mean cardiopulmonary bypass time (144.33 vs. 84.34 min and aortic cross-clamp time (78.5 vs. 41.46 min were significantly higher in group A. While the blood and products usage was significantly higher in Group A, there was no difference in indexed postoperative drainage in first 4, 8 and 12 h and postoperative coagulation parameters. Mean C-reactive protein was less in Group A than B and renal dysfunction was seen more in Group A (25% vs. 7.6%. Mortality in Group A was 16.66% and 7.6% in Group B. Conclusion: Anti-fibrinolytics have a definitive role in high-risk children who undergo open-heart surgery. Tranexamic acid is as equally effective as aprotinin with no additional increase in morbidity or mortality. Ultramini Abstract: Coagulopathy has been a major issue in pediatric cardiac surgery, and anti-fibrinolytics have been used fairly regularly in various settings.

    Most thoracopagus twins present with cardiac fusion and associated congenital cardiac defects, and assessment of this anatomy is of critical importance in determining patient care and outcome. Cardiac CT with electrocardiographic triggering provides an accurate and quick morphological assessment of both intracardiac and extracardiac structures in newborns, making it the best imaging modality to assess thoracopagus twins during the neonatal period. In this case report, we highlight the diagnostic value of cardiac CT in thoracopagus twins with an interatrial channel and complex congenital cardiac defects. (orig.)
