SUMMARY -Breast cancer is the most frequently diagnosed cancer and the leading cause of death from cancer in women. Th e accuracy of diagnosis can be increased with a combination of clinical examination, imaging diagnostics, and fi ne needle aspiration cytology (FNAC) or core needle biopsy, also known as triple test. Th e aim of the study was to evaluate the sensitivity and specifi city of FNAC in the diagnosis of breast tumors in our institution by correlating it with histopathology fi ndings. We assessed the accuracy of 124 FNAC fi ndings by comparing cytological diagnosis of breast masses with the diagnoses from histopathology reports obtained by surgery. Statistical analysis showed 95.1% accuracy, 97.7% sensitivity, 89.1% specifi city, 95.5% positive predictive value and 94.2% negative predictive value of FNAC. Study results indicated that FNAC could be used as a highly reliable tool in the diff erential diagnosis of breast tumors, in combination with clinical and imaging fi ndings, especially in developing countries with limited fi nancial resources.
Introduction: Urine neutrophil gelatinase-associated lipocalin (uNGAL) is a biochemical marker significant for early prediction of acute kidney
injury in adults. However, it has not been examined sufficiently among the infant population, particularly newborns in terms of reference values.
The aim of our study was to determine the concentration of uNGAL in healthy term newborns and to determine if there was a difference in uNGAL
concentration according to gender, postnatal age and birth weight.
Materials and methods: Our study involved 81 healthy term newborns birth (≥ 37 weeks, Apgar score ≥ 8 in the first minute after birth, CRP < 5
mg/L). Urine NGAL was measured using chemiluminescent microparticle immunoassay (CMIA) within 72 hours after birth, on Architect plus ci8200
analyser (Abbott, Chicago, USA). Data were analysed using Statistica software.
Results: The median concentration of uNGAL in the whole study group of healthy term newborns was 27.1 ng/mL (16.5-56.0 ng/mL) (newborn girls,
27.1 ng/mL (15.8-47.9 ng/mL); newborn boys, 27.9 ng/mL (16.5-61.0 ng/mL), P = 0.941). Median uNGAL concentration according to postnatal age
expressed in days was 28.2 ng/mL (11.7-57.2 ng/mL) 1st day, 28.9 ng/mL (16.5-64.2 ng/mL ) 2nd day and 23.9 ng/mL (20.2-46.6) 3rd day, P = 0.863.
Regarding birth weight for newborns < 3500 g, median concentration was 25.0 ng/mL (16.5-45.4 ng/mL ) and for weight ≥ 3500 g 30.6 ng/mL
(16.5-64.2 ng/mL), P = 0.455.
Conclusions: There were no significant difference in uNGAL concentration in relation to gender, postnatal age and birth weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
