Henri-Louis Roger
Henri-Louis Roger (6 January 1809 – 15 November 1891) was a French pediatrician born in Paris. He studied medicine in Paris, earning his doctorate in 1839 with a dissertation on auscultation titled ''De l'auscultation et se valeur semiologique''. In 1847 he became agrégé at the medical faculty of Paris, and from 1860 was associated with the Hôpital Sainte-Eugénie. Here he focused his efforts on post-mortem investigations of children. In 1862 he became a member of the Académie de Médecine. In addition to his work in pediatrics, he is remembered for contributions made involving cardiological issues. His name is lent to two eponymous terms: ''Maladie de Roger'' (Roger's disease), which is a small congenital asymptomatic ventricular septal defect (VSD), and ''bruit de Roger'' (Roger's murmur), which is a loud pansystolic murmur of a ventricular septal defect. With pathologist Jean Baptiste Barth (1806-1877), Roger published works on auscultation, including "A Manua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interventricular Septum
The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another. The ventricular septum is directed obliquely backward to the right and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior interventricular sulci. The lower part of the septum, which is the major part, is thick and muscular, and its much smaller upper part is thin and membraneous. During each cardiac cycle the interventricular septum contracts by shortening longitudinally and becoming thicker.

Patrick Newbigging
Patrick Small Keir Newbigging FRSE FRSSA FRCSE (1813–1864) was a Scottish surgeon and general practitioner. He was President of the Royal Medical Society and of the Royal Scottish Society of Arts. Together with his father, Sir William Newbigging he formed one of the few father-son pairs of former Presidents of the Royal College of Surgeons of Edinburgh. His observations on the origin of the heart sounds and of the apex beat of the heart made a significant contribution to the debate. Early life He was born at 18 St Andrew Square in Edinburgh's New Town the son of Lilias Steuart and her husband, the Edinburgh surgeon Sir William Newbigging. He studied medicine at the University of Edinburgh. While a student he joined the Royal Medical Society and gave a dissertation to the Society in 1833 on the origin of heart sounds and pulsations. In this he suggested that the apex beat was produced by ventricular systole and not diastole as had been suggested by William Stokes and Domin ...

Jean Baptiste Barth
Jean Baptiste Philippe Barth (24 September 1806 – 20 November 1877) was a French pathologist who was a native of Sarreguemines. He studied medicine at the University of Paris, and was afterwards an assistant to Pierre Charles Alexandre Louis (1787-1872) at the Hôpital de la Pitié. In 1840 he was appointed ''médecin des hôpitaux'', and practiced medicine in Parisian hospitals for the next thirty years. In 1871 he was elected vice president of the Académie de Médecine, and soon afterwards became its president. Jean Barth is remembered for treatises on auscultation that he co-authored with pediatrician Henri-Louis Roger (1809-1891). These include "A Manual of Auscultation and Percussion" and "A Practical Treatise on Auscultation"; both being translated into English. Associated eponym * "Barth's hernia": A hernia of the loops of intestine between a persistent vitelline duct and the serosa of the abdominal wall.

Pathologist
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomy ...

Heart Murmur
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. Turbulent blood flow is not smooth. The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing. The major way health care providers examine the heart on physical exam is heart auscultation; another clinical technique is palpation, which can detect by touch when such turbulence causes the vibrations called cardiac thrill. A murmur is a sign found during the cardiac exam. Murmurs are of various types and are important in the detection of cardiac and valvular pathologies (i.e. can be a sign of heart diseases or defects). There are two types of murmur. A functional murmur is a benign heart murmur that is primarily due to physiologic conditions outside the heart. The other type of heart murmur is due to ...

Pediatrician
Pediatrics ( also spelled ''paediatrics'' or ''pædiatrics'') is the branch of medicine that involves the medical care of infants, children, adolescents, and young adults. In the United Kingdom, paediatrics covers many of their youth until the age of 18. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21, but some pediatric subspecialists continue to care for adults up to 25. Worldwide age limits of pediatrics have been trending upward year after year. A medical doctor who specializes in this area is known as a pediatrician, or paediatrician. The word ''pediatrics'' and its cognates mean "healer of children," derived from the two Greek words: (''pais'' "child") and (''iatros'' "doctor, healer"). Pediatricians work in clinics, research centers, universities, general hospitals and children's hospitals, including those who practice pediatric subspecialties (e.g. neonatology requires resources available in a NICU).

Systole (medicine)
Systole ( ) is the part of the cardiac cycle during which some chambers of the heart contract after refilling with blood. The term originates, via New Latin, from Ancient Greek (''sustolē''), from (''sustéllein'' 'to contract'; from ''sun'' 'together' + ''stéllein'' 'to send'), and is similar to the use of the English term ''to squeeze''. The mammalian heart has four chambers: the left atrium above the left ventricle (lighter pink, see graphic), which two are connected through the mitral (or bicuspid) valve; and the right atrium above the right ventricle (lighter blue), connected through the tricuspid valve. The atria are the receiving blood chambers for the circulation of blood and the ventricles are the discharging chambers. In late ventricular diastole, the atrial chambers contract and send blood to the larger, lower ventricle chambers. This flow fills the ventricles with blood, and the resulting pressure closes the valves to the atria. The ventricles now perfo ...
