|The term stenosis refers to the narrow and pyloric refers to the stomach so pyloric stenosis is the narrowing of the opening of stomach to the ileum or the first portion of small intestine. Thus it affects the gastrointestinal tract leading to many stomach problems. It generally affects the babies because in them there is broadening of the pylorus muscles in the stomach without known cause due to which the pyloric opening gets narrower. The signs and symptoms of pyloric stenosis include vomiting, hungry after vomiting and in some cases peristalsis may occur in the upper abdomen of the babies. As the baby is unable to take food properly so the baby may suffer from weight loss. Pyloric stenosis may occur due to genetic and environmental factors and no known cause is known till now. If pyloric stenosis is not cured at proper time then it may lead to jaundice or diarrhea. The treatment for pyloric stenosis includes the opening of the pyloric space so that the food can reach the small intestine and it can be done by surgery called pyloromyotomy with the help of endoscope.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
