most of the erythrocyte related diseases are detectable by hematology images analysis. at the first step of this analysis, segmentation and detection of blood cells are inevitable. in this study, a novel method using a line operator and watershed algorithm is rendered for erythrocyte detection and segmentation in blood smear images, as well as reducing over-segmentation in watershed algorithm t...

OBJECTIVE Therapy-related myeloid neoplasms (t-MN) account for approximately 10% to 20% of all cases of AML (acute myeloid leukemia), MDS (myelodysplastic syndrome) and MDS/MPN (myelodysplastic syndrome/myeloproliferative neoplasms), MDS, and MDS/MPN. In our study, we evaluated peripheral blood smear samples and hemogram values in breast cancer patients who were receiving adjuvant anthracycline...

A microscopic examination of an appropriately prepared and well-stained blood smear by a knowledgeable laboratory professional is necessary and clinically useful in a number of circumstances and for a variety of reasons. In this article, an attempt is made to delineate the purpose and criteria for blood smear examination in a variety of circumstances that are encountered in everyday laboratory ...

Histoplasmosis is endemic in the American continent and also in Sub-Saharan Africa, coexisting with the African histoplasmosis. Immunosuppressed patients, especially those with advanced HIV infection develop a severe disseminated histoplasmosis with fatal prognosis. The definitive diagnosis of disseminated histoplasmosis is based on the detection of Histoplasma capsulatum from patient' tissues ...

Examination of the peripheral blood smear showed severe Plasmodium falciparum infection (parasitemia 1% and 1 schizont). In addition, there were numerous examples of hemophagocytosis on the peripheral blood smear. The top left panel shows a monocyte with particulate debris, perhaps remnants of the malarial infection. The top right panel shows a red cell engulfed by a monocyte. On the bottom lef...

Neuroacanthocytosis is an autosomal recessive neurodegenerative disease, characterized by chorea, dementia, seizure, acanthocytes on peripheral blood smear and caudate atrophy on brain magnetic resonance imaging (MRI).1,2 These patients have severe orofacial dyskinesia and especially eating dystonia that causes severe eating problems and tongue and cheek biting. Eating or feeding dystonia, in c...
