RESUMEN
To analyze the working conditions and evaluate the effectiveness of blood smear examinations in fever patients after the start of national malaria elimination program (NMEP), and explore the suitable strategy for malaria diagnosis and surveillance in NMEP, so as to provide the evidence for the development and adaptation of malaria elimination strategies and measures in Jiangsu Province.The data of malaria epidemic situation reported by network, fever patients’ blood test tables, and epidemiological surveys of malaria cases were collected and statistically analyzed by SPSS 16.0 in Jiangsu Province from 2010 to 2016.A total of 2 367 cases of malaria cases were reported from 2010 to 2016. Among the 3 691 188 person-times of fever patients tested, there were 2 252 positives (0.06%). The number of blood tests of fever patients decreased from 742 900 in 2010 to 277 000 in 2016. At the same time, the positive rate increased from 0.04% in 2010 to 0.16% in 2016. The positive rate of blood tests of fever patients in 2016 was significantly higher than that in 2010 (χ2 = 161.61, P < 0.01). From 2010 to 2016 in Jiangsu province, the centers for disease control and prevention of cities and counties, that completed the blood review within 3 days, deleted 273 negative cases. In 2010, the centers for disease control and prevention of cities and counties deleted 61 negative cases, but in 2016, the centers deleted only 14 negative cases, and the negative rate of blood review in 2010 was significantly higher than that in 2016 (χ2 = 22.99, P < 0.01).A large number of blood smear examinations have been tested in fever patients in Jiangsu Province. It not only conforms to the strong monitoring system requirements issued by World Health Organization (WHO) in malaria elimination, but also provides the evidence for no local malaria case in Jiangsu since 2012.
RESUMEN
Background: Pediatric anemia is a global phenomenon. The magnitude of this problem gets exaggerated in developing countries like India wherein majority of the population are vulnerable since they live in rural areas and come under low socio-economic status. Though pediatric anemias can be diagnosed by simple blood tests like complete hemogram and peripheral smear examination, the evaluation of underlying etiological factor to initiate appropriate therapy involves expensive work up which may not be affordable in a rural setup. This need-based study of pediatric anemia was conducted to determine the morphological patterns of anemia by simple baseline investigations and to detect the related etiologic factor. Methodology: The probable etiological factors contributing to the anemias were diagnosed by determining the morphological patterns using simple baseline investigations like complete hemogram and peripheral blood examination and treated accordingly. Conclusion: The etiology of microcytic hypochromic anemia was found out to be iron deficiency as confirmed by serum iron profile studies. Presence of dimorphic anemia suggested combined nutritional deficiency of Iron, vitamin B12 deficiency or folate. Hemolytic anemias detected by routine hematological investigations were confirmed by serum electrophoresis. Morphological examination of red blood cells on peripheral smear examination is thus an effective, simple and cost effective method to determine the etiology of various types of anemia.
RESUMEN
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 hematology practice. A blood smear scan serves to at least (a) verify the flagged automated hematology results and (b) determine if a manual differential leukocyte count needs to be performed. Blood smear examination/manual differential leukocyte count with complete blood count (CBC) provides the complete hematologic picture of the case, at least from the morphologic standpoint. Blood smear review with or without interpretation serves to ensure that no clinically significant finding is missed, besides providing diagnosis or diagnostic clue(s), particularly if and when interpreted by a physician.
