A new method for fast and simple segmentation of peripheral blood smears using Teager energy operator (TEO) is presented. The two-pan algorithm efficiently segments leucocytes present in the smear into nucleus and cytoplasm. The local mean weighted high pass filtering property of Teager energy operator is used to identify and distinguish the nucleus of white blood cells. Cytoplasm present in th...

A 78-year-old woman hospitalized for investigation of ascites presented with weakness, loss of appetite, fever, and chills. A complete blood count showed anemia, leukocytosis, and thrombocytopenia (hemoglobin, 8.5 g/dL; leukocytes, 27.5 3 10/L; platelets, 50 3 10/L). Peripheral blood smear demonstrated the presence of neutrophilia with left shift (promyelocytes, 0.3 3 10/L; myelocytes, 1.9 3 10...

Aggressive natural killer cell leukemia (ANKL) is an extremely rare type of leukemia characterized by clonal NK cell infiltration of peripheral blood and the bone marrow, cytopenias, and hepato/splenomegaly. ANKL is an aggressive subtype of a large granular lymphocytic (LGL) leukemia. Peripheral blood smear shows LGL cells containing characteristic azurophilic granules in a light pale basophili...

Filariasis is a major public health problem in tropical countries like India. Conventional diagnosis is by demonstrating microfilariae (MF) in the peripheral blood smear. Nocturnal periodicity of the species endemic in India makes it difficult to find microfilariae in blood. Incidental detection of microfilariae (MF) in fine needle aspiration cytology (FNAC) smears of various sites in clinicall...

Background:Raw opium is a kind of drug, abused a lot in Iran. In a vast majority of cases, various impurities including lead are added to raw opium. This study aimed to evaluate Blood Lead Level (BLL) and probable clinical symptoms triggered by it among opium abusers. Methods:This study was case control and conducted on 40 patients addicted to raw opium (case group) and 40 patients without any ...

Chanarin-Dorfman syndrome is a rare, genetically determined autosomal recessive disorder, characterised by the presence of lipid droplets in the cytoplasm of multiple tissues of the body, particularly in the blood leukocytes and congenital non-bullous icthyosiform erythroderma. In this paper, we report one-year child who presented with skin lesions since birth and hepatomegaly. Liver biopsy sho...
