КЛИНИЧЕСКОЕ ЗНАЧЕНИЕ ПОЛИМОРФНОЯДЕРНЫХ НЕЙТРОФИЛОВ В СТРАТИФИКАЦИИ ДЕТЕЙ С ОСТРОЙ БОЛЬЮ В ЖИВОТЕ

Background. Acute abdominal pain in children is defined as acute pain of non-traumatic genesis lasting up to 5-7 days, and presents a serious diagnostic and tactical problem. Many aspects of diagnosis and treatment remain controversial. Aim. To determine the clinical significance of polymorphonuclear neutrophil count in the stratification of children with acute abdominal pain. Material and Methods. A prospective randomized blind clinical trial was performed. The results of examination and treatment of 633 children admitted to Grodno Regional Children's Clinical Hospital with acute abdominal pain were analyzed. The number of polymorphonuclear neutrophils was analyzed in relative (PNRV) and absolute (PNAV) values. Statistics included evidence-based criteria, ROC and precision-recall curve analysis, Kullback's measure of informativeness (Jxi), Bayes' theorem. Results. Separation points were determined for the PNRV and PNAV tests. It was 65% for the PNRV test and 8.952×109/L for the PNAV test. For PNRV values less than 65%, the probability of acute appendicitis (AA) as a cause of acute abdominal pain was 1.8% (CI 0.2 to 3.4); the overall informative value was 2.94. With PNAV test values less than 6.5×109/L, the probability of AA was 1.2% (CI 0.03 to 2.4%); the overall informative value was 5.24. It was demonstrated that an increase in test values above the indicated values did not significantly increase the probability of AA as a cause of acute abdominal pain in children. Conclusion. The tests studied are highly informative and can be used to stratify patients with acute abdominal pain. It is necessary to validate the results obtained taking into account the specific capabilities of a given medical institution and the type of equipment used.

Penggunaan Ringkasan Materi Essensial Sesuai SKL untuk Meningkatkan Nilai Try Out Biologi

<p>The purpose of this action to enhance the understanding of biology as a whole so as to improve the academic achievement that can be seen from the increase in value of test. Class actions performed included two cycles through the four stages, namely planning, action, observation and reflection. Through class actions carried out the verdict that the use of a summary of essential materials in accordance SKL can enhance students' understanding of biological materials because it can ease the burden on students in the study of biology as a whole class of biological materials in X to the biological material in class XII. However, keep in mind in making these summaries are designed for a structured arrangement with images made so attractive, clear, and if necessary choose the images that often come out in the previous state exams. <br /><br /></p>
