Linfoma leucemizado em felino coinfectado com os vírus da imunodeficiência felina e da leucemia felina: relato de caso / Lymphoma in leukemic phase in feline coinfected with feline immunodeficiency virus and feline leukemia virus: case report

O presente trabalho teve por objetivo relatar um caso de linfoma leucemizado em um felino coinfectado com os vírus da imunodeficiência felina (FIV) e o da leucemia felina (FeLV). Foram realizados exames de hemograma, contagem de reticulócitos, mielograma, bioquímica, teste de imunocromatografia para FIV e FeLV, imunofluorescência indireta (IFA) para FeLV, radiografia torácica e citologia renal. Esse último exame revelou um linfoma extranodal. Foi determinante para a conclusão diagnóstica a associação dos sinais clínicos corroborados com a infiltração de elevada quantidade de células linfoblásticas na medula óssea, exibindo critérios citomorfológicos de malignidade, como mitoses atípicas, relacionadas à presença de corpúsculos linfoglandulares e material hematopoiético inter-relacionado. O linfoma é uma neoplasia relativamente comum em felinos, entretanto, a apresentação leucemizada é rara, podendo representar um desafio diagnóstico clínico, o que torna fundamental a inclusão da citologia medular na prática clínica dessa espécie.(AU)

The present study aimed to report a case of lymphoma in leukemic phase in feline coinfected with feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). Blood counts, reticulocyte counts, bone marrow avaluation, biochemistry, immunochromatography assay for FIV and FeLV, indirect immunofluorescence (IFA) for FeLV, thoracic radiography and renal citology were performed. This last examination revealed extranodal lymphoma. The association of the clinical signs with the infiltration of a high number of lymphoblastic cells in the bone marrow with cytomorphological criteria of malignancy, atypical mitoses, lymphoglandular corpuscles and hematopoietic material were determinant for the diagnostic conclusion. Lymphoma is a relatively common neoplasm in felines, however the leukemic phase is rare and may represent a clinical diagnostic challenge, making it essential to include bone marrow cytology in the clinical practice of this species.(AU)

Reform and practice of comprehensive experimental teaching in clinical hematology laboratory course / 中华医学教育探索杂志

To train the talents of clinical laboratory for the demand of clinical jobs,it is necessary to make the experimental teaching reform of clinical laboratory hematology.Comprehensive experimental teaching,which centers on case,has been explored in many ways like prefessional teachers' training,cases' choose,teaching method and experimental examination.And the practice has proved that the reform of comprehensive experimental teaching can give full play to the students' initiative and creativity,foster the students' ability to analyze and diagnose hematopathy.

Study on experimental teaching reform of the clinical hematology and hematologic examination / 中华医学教育探索杂志

Clinical hematology and hematologic examination is a strong practical curriculum, and experimental class is very important in the aspects of teaching.In order to improve the quality of teaching and train compound laboratory talents with high quality,several effective reform mea-sures were carried out based on the years of teaching practice by the department:improving the methods of experimental teaching;using modern means of teaching;emphasizing on the analysis of experimental results,formulating the rigorous experimental evaluation system and starting the second class etc.
