Review of Kawasaki Disease

Abstract Background: Kawasaki disease is one of the leading causes of acquired heart disease in children. It is an acute self-limited vasculitis that predominantly affects infants and children younger than 5 years of age. These patients present with nonspecific symptoms, such as fever and lymphadenopathy, making the diagnosis challenging. This disease can have serious and potentially fatal outcomes, and prompt recognition of this disease is vital to the patient’s outcome. We present a complete review of the disease, including the epidemiology, pathophysiology, diagnosis and management of acute Kawasaki disease, the natural history of this disease, and follow up of these patients as they transition into the adult cardiology practice. Methods: Our systematic review information were collected from articles retrieved from PubMed library. Keywords that were used included; Kawasaki disease, coronary artery disease, coronary artery aneurysm, pediatric coronary artery disease, epidemiology of Kawasaki disease and treatment of Kawasaki disease. We included only relevant to the topic articles. No exclusion criteria were applied. Conclusions: Kawasaki disease incidence tends to be increasing over the last decade in the united states. Seasonality of the disease has been described in Japan. It is a mysterious disease with unknown etiology, however, multiple hypotheses have been proposed and tested to explain the pathophysiology. As this disease has an associated high morbidity and mortality, prompt recognition and management of this disease is important to the patient’s overall prognosis and survival

The Multilayered Atrium: An Unusual Case of a Life-Threatening Cor Triatriatum With Persistent Levotrial Cardinal Vein in a 2-Month-Old Infant

Cor triatriatum sinister (CTS) is a rare congenital cardiac malformation. In CTS, a fibromuscular membrane subdivides the left atrium into 2 chambers. The communication between the 2 chambers is through 1 or more orifices in the dividing membrane. We present an interesting case of a 2-month-old infant with obstructed CTS membrane who first presented on account of poor feeding and failure to thrive. Echocardiography showed a persistent levoatrial cardinal vein (LACV) connecting the left atrium and the innominate vein. This allowed the proximal left atrial chamber to decompress its blood volume into the innominate vein and subsequently the superior vena cava. There was minimal prograde blood flow across the Cor triatriatum membrane, so the majority of pulmonary venous blood ultimately returned to the heart by way of the decompressing vertical vein into the systemic venous circulation. Surgical repair was performed with an uneventful postoperative course. The specific anatomical variant of Cor triatriatum found in our subject has rarely been reported

Undergraduate medical students’ perceptions, attitudes, and competencies in evidence-based medicine (EBM), and their understanding of EBM reality in Syria

Abstract Background Teaching evidence-based medicine (EBM) should be evaluated and guided by evidence of its own effectiveness. However, no data are available on adoption of EBM by Syrian undergraduate, postgraduate, or practicing physicians. In fact, the teaching of EBM in Syria is not yet a part of undergraduate medical curricula. The authors evaluated education of evidence-based medicine through a two-day intensive training course. Methods The authors evaluated education of evidence-based medicine through a two-day intensive training course that took place in 2011. The course included didactic lectures as well as interactive hands-on workshops on all topics of EBM. A comprehensive questionnaire, that included the Berlin questionnaire, was used to inspect medical students’ awareness of, attitudes toward, and competencies’ in EBM. Results According to students, problems facing proper EBM practice in Syria were the absence of the following: an EBM teaching module in medical school curriculum (94%), role models among professors and instructors (92%), a librarian (70%), institutional subscription to medical journals (94%), and sufficient IT hardware (58%). After the course, there was a statistically significant increase in medical students' perceived ability to go through steps of EBM, namely: formulating PICO questions (56.9%), searching for evidence (39.8%), appraising the evidence (27.3%), understanding statistics (48%), and applying evidence at point of care (34.1%). However, mean increase in Berlin scores after the course was 2.68, a non-statistically significant increase of 17.86%. Conclusion The road to a better EBM reality in Syria starts with teaching EBM in medical school and developing the proper environment to facilitate transforming current medical education and practice to an evidence-based standard in Syria.</p

Wearable Seismocardiography‐Based Assessment of Stroke Volume in Congenital Heart Disease

Background Patients with congenital heart disease (CHD) are at risk for the development of low cardiac output and other physiologic derangements, which could be detected early through continuous stroke volume (SV) measurement. Unfortunately, existing SV measurement methods are limited in the clinic because of their invasiveness (eg, thermodilution), location (eg, cardiac magnetic resonance imaging), or unreliability (eg, bioimpedance). Multimodal wearable sensing, leveraging the seismocardiogram, a sternal vibration signal associated with cardiomechanical activity, offers a means to monitoring SV conveniently, affordably, and continuously. However, it has not been evaluated in a population with significant anatomical and physiological differences (ie, children with CHD) or compared against a true gold standard (ie, cardiac magnetic resonance). Here, we present the feasibility of wearable estimation of SV in a diverse CHD population (N=45 patients). Methods and Results We used our chest‐worn wearable biosensor to measure baseline ECG and seismocardiogram signals from patients with CHD before and after their routine cardiovascular magnetic resonance imaging, and derived features from the measured signals, predominantly systolic time intervals, to estimate SV using ridge regression. Wearable signal features achieved acceptable SV estimation (28% error with respect to cardiovascular magnetic resonance imaging) in a held‐out test set, per cardiac output measurement guidelines, with a root‐mean‐square error of 11.48 mL and R2 of 0.76. Additionally, we observed that using a combination of electrical and cardiomechanical features surpassed the performance of either modality alone. Conclusions A convenient wearable biosensor that estimates SV enables remote monitoring of cardiac function and may potentially help identify decompensation in patients with CHD
