CEL, NOS), is a leukemia-inducing disorder in the eosinophil cell lineage that causes eosinophil blood counts greater than 1,500/μL. The most recent (2017) World health organization criteria specifically excludes from this disorder hypereosinophilia/eosinophilia associated with BCR-ABL1 fusion gene-positive chronic myeloid leukemia, polycythemia vera, essential thrombocytosis, primary myelofibrosis, chronic neutrophilic leukemia, chronic myelomonocytic leukemia, atypical chronic myelogenous leukemia, clonal eosinophilias involving gene rearrangements of PDGFRA, PDGFRB, or FGFR1, and chromosome translocations that form PCM1-JAK2, ETV6-JAK2, or BCR-JAK2 fusion genes. For this diagnosis, immature eosinophil (e.g. myeloblast) cell counts in the bone marrow and peripheral blood must be less than 20% and the chromosomal alterations (inv(16)(p13.1q22)) and t(16;16)(p13;q22) as well as other features diagnostic of acute myelogenous leukemia must be absent. The latter diagnostic features include clonal cytogenetic abnormalities and molecular genetic abnormalities diagnostic for other forms of leukemia or the presence of myeloblast counts greater than 55% in bone marrow or 2% in blood. Chronic eosinophilic leukemia may transform into acute eosinophilic or other types of acute myelogenous leukemia. Familial eosinophilia
Familial eosinophilia is a rare congenital disorder characterized by the presence of sustained elevations in blood eosinophil levels that reach ranges diagnostic of eosinophilia or, far more commonly, hypereosinophilia. It is an autosomal dominant disorder in which genetic linkage gene mapping family studies localize the gene responsible for it to chromosome 5 at position q31–q33, between markers D5S642 and D5S816.
Usually, a red color indicates a flow toward the ultrasound transducer, while blue indicates a flow away from the transducer. Based on the display, doctors can evaluate blood flow to the umbilical arteries, umbilical veins, or other organs such as heart and brain. Nonstress test
Nonstress test (NST) is a type of electronic fetal monitoring that uses a cardiotocograph to monitor fetal heartbeat, fetal movement and mothers contraction. NST is typically monitored for at least 20 minutes. Signs of a reactive (normal) NST include a baseline fetal heart rate (FHR) between 110 and 160 beats per minute (bpm) and 2 accelerations of FHR of at least 15 bpm above baseline for over 15 seconds. Vibroacoustic stimulation and longer monitoring may be needed if NST is non-reactive. Biophysical profile
A biophysical profile is a noninvasive procedure that uses the ultrasound to evaluate the fetal health based on NST and four ultrasound parameters: fetal movement, fetal breathing, fetal muscle tone, and the amount of amniotic fluid surrounding the fetus. A score of 2 points is given for each category that meets the criteria or 0 points if the criteria are not met (no 1 point). Sometimes, the NST is omitted, making the highest score 8/8 instead of 10/10. Generally, a score of 8/10 or 10/10 is considered a normal test result, unless 0 points is given for amniotic fluid. A score of 6/10 with normal amniotic fluid is considered equivocal, and a repeated test within 24 hours may be needed.
