83 burn patients with the syndrome of bacterial infection and intoxication associated with leucopenia were divided in to 2 groups, the one of 32 patients without transfusion of white blood granulocyte, the other 51 patients with a transfusion rich with neutrophile leucocyte. Results: In the group of the syndrome of severe bacterial infection and intoxication associated with leucopenia, 39.2% have had complication, less than no transfusion group (68.7%). Mortality of the transfusion group: 82.4%, is higher than no transfusion group: 40.6%

We found an unusual morphology of eosinophil nucleus having longer chromatin filament in addition to a single narrow chromatin bridge. The nucleus having two chromatin filament bridge looked like two legged eosinophil, instead of usual glasses shape. As the physiologic function of the nucleus of granulocyte segmentation and the mechanism by which the lobes are formed during differention is still unknown, we could not know the definite nature and significance of these double chromatin filament. However we could suggest that they may be a reactive change of eosinophilia. This not uncommon morphology has not been described as yet. Here we report three cases of unusual morphology of eosinophil nucleus presenting double chromatin filament bridge, one case with a band form nucleus looked like ring shape, with brief review of literatures.

Agranulocytosis as a side effect of clozapine has been reported to be associated with initial phases of treatment, i.e., first six months. Agranulocytosis with clozapine during the initial phases of treatment has been linked to genetic vulnerability in the form of variations in the human leukocyte-antigen haplotypes. However, there is limited literature on late onset agranulocytosis with clozapine and this has very rarely been linked to human leukocyte-antigen haplotypes vulnerability. In this report we review the existing data on late onset agranulocytosis with clozapine and describe the case of a young man, who developed agranulocytosis with clozapine after 35 months of treatment and was found to have genetic vulnerability in form of being positive for HLA DR4. This case highlights underlying autoimmune immune mechanism in clozapine-induced agranulocytosis and the need for frequent blood count monitoring on clozapine even after the initial 6 months of starting treatment especially in patients with genetic vulnerability to develop this condition.

BACKGROUND: We evaluated the performance of leukocyte differential counting and clinical usefulness of the morphologic flags of the SE-000, and set optimal criteria for selecting and reviewing the specimens with increased abnormal cells. METHODS: From the results of SE-000 and manual leukocyte differential counting in 100 healthy control and 520 patient specimens we evaluated the correlations on the leukocyte fractions as well as the frequency, sensitivity and false positivity of the flags. After determination of the review criteria we calculated total review rate from the 3,403 consecutive CBC specimens. RESULTS: In both control and patient groups the correlation between two methods was high with the exception of monocytes and basophils. Regarding the morphologic flags, Blast was sensitive (86.9%) however could not detect mature looking lymphoblasts. Immature granulocyte showed high sensitivity (93.7%). Left shift showed the highest frequency (34.6%) and false positive rate (82.8%). Atypical lymphocytes and NRBC showed relatively low sensitivity (63.6%, and 50.5%, respectively). We determined to review the slide when 1) All morphologic flags except Left shift are marked, 2) WBC <3,000/microliter or >20,000/microliter, Hb <8.0 g/dL or 18.0 g/dL, Platelet <100,000/microliter or >600,000/microliter, 3) Severe deviation of leukocyte fractions or 4) Specially requested by physician. As a result, total review rate was 25.0% while 14 abnormal cases with no flags could be additionally detected. CONCLUSIONS: A new review criteria determined from the results of CBC and leukocyte differential together with morphologic flags could reduce the review rate without skipping the abnormal cases.
