Methimazole is a widely used and generally well-tolerated antithyroid agent. Adverse reactions occur in 1~5% of patients taking methimazole medication, but these are most commonly transient, benign leukopenia and a skin rash. Severe cholestatic jaundice, combined with agranulocytosis, has been known as a rare complication. Herein, a case of methimazole induced cholestatic jaundice, with agranulocytosis, is reported.

Antipsychotic-induced agranulocytosis is a significant side effect that is known to occur with most of the antipsychotic medications. It usually resolves once the medications are stopped and patients are able to be switched over to another antipsychotic medication. Lurasidone has not been reported to cause leukopenia and neutropenia. This case report is of a patient with a past history of risperidone induced-aganulocytosis developing dose related leukopenia and neutropenia with lurasidone.

The acute effects of variable dos rates to total body irradiation (TBI) were investigated with 600 cgy of single exposure in the mice as a preclinical model. Total 80 mice (ICR) were used. Twenty of which served as controls, receiving no irradiation. All irradiated mice showed a universal decline in their weight and white blood cell count. The degree of weight loss and leukopenia were similar at 3 different dos rate but slightly prominent with 15 cgy/minute group. The degree of recovery among the groups showed no dose rate dependence. Our results suggest that TBI with 15 cgy/minute may be applicable for clinical therapy with careful evaluation of patient's condition.

The novel antipsychotic, olanzapine, has structural and pharmacological properties similar to clozaine. Antipsychotic drugs, as well as mood stabilizers, can cause neutropenia, which can progress to life-threatening agranulocytosis if the medication is not discontinued. We report two cases of reversible neutropenia associated with a olanzapine-valproate combination treatment. This report suggests that patients treated with the combination of olanzapine and valproate should be monitored for the occurrence of leukopenia and neutropenia.

An increase in the dose of chemotherapy enhances the response of many experimental and clinical cancers, but the extent of chemotherapy dose escalation and repeated use is often limited by myelosuppression. The side effects of chemotherapy including bleeding and infection due to myelosuppression have resulted in delayed therapy and a reduction in the therapeutic dose, therefore it is necessary to overcome myelosuppression especially leukopenia in patients with gynecologic malignancies who recieved chemotherapy. This study is undertaken to investigate the clinical effects of rhG-CSF(recombinant human Granulocyte-colony stimulating factor) in 29 patients with gynecologic malignancy who recieved chemotherapy. It was given at a dose of 100 microgram bid/day subcutaneously until significantly increase of leukocyte count in leukopenic patient. The results showed, the rhG-CSF has significantly increased the number and function of leukocyte. The use of rhG-CSF was effective and useful to treat chemotherapy induced leukopenia and to accelerate the recovery from this complications.

PURPOSE: We wanted to compare the efficacy and toxicity of chemotherapy with methotrexate, vinblastine, adriamycin, cisplatin(M-VAC) versus gemcitabine and cisplatin(GC) for patients with advanced or metastatic urothelial carcinoma. MATERIALS AND METHODS: Forty-nine patients diagnosed with advanced urothelial cell carcinoma and who were started on chemotherapy were divided into two groups. All of them had a 0-1 Eastern Cooperative Oncology Group performance status. 19 patients received M-VAC chemotherapy and 30 patients received the GC regimen. Among them, the subjects who completed more than 3 cycles of their recommended formula (13/19 for M-VAC, 28/30 for GC) were included in this study. They were evaluated for their overall response rate, the 5-year survival rate, toxicities and the drop-out rate. RESULTS: The overall response rate and median survival period of the M-VAC and G-C groups were 38%(5/13 cases) and 46%(13/28 cases), and 16.7 months and 43.9 months, respectively. The 5-year survival rates in the two groups were 10% in the M-VAC group and 46% in the G-C treated group(p=0.013). The main hematologic complication was leukopenia and this occurred in 10/19 patients and more than grade 3 leukopenia was noted in 4/10 patients in the M-VAC group and in 19/30 patients and more than grade 3 was noted in 10/19 patients in the GC group.The common non-hematologic side effects between the two groups were nausea/vomiting(84.2% vs 47.7%), alopecia(47.4% vs 26.7%), diarrhea(15.8% vs 16.7%), and nephrotoxicity(15.8% vs 6.7%), respectively. The drop-out rates were 31.6% in the M-VAC group and 6.7% with the GC group. CONCLUSIONS: For patients with a good performance status with advanced or metastatic urothelial carcinoma, GC chemotherapy is more effective and it has more tolerable toxicities than does the M-VAC regimen.

Among the various side effects of anticonvulsant medication, the anticonvulsant hypersensitivity syndrome (AHS) is underrecognized. This condition developed frequently with aromatic anticonvulsants, but with new antiepileptic drugs as well. We experienced three lamotrigine-induced AHS cases with symptoms such as fever, rash, leukopenia, eosinophilia and lymphadenopathy, which subsided after withdrawal of lamotrigine.

BACKGROUND: We evaluated the efficacy of white blood cell (WBC) differential counts in severely leukopenic samples by the Hematoflow method and by automated hematology analyzers and compared the results with manual counts. METHODS: EDTA-anticoagulated blood samples (175 samples) with WBC counts of 40-990/microL were selected. Hematoflow differential counts were performed in duplicates employing flow cytometry using the CytoDiff reagent and analysis software. Differential counts were also performed using the DxH 800 (Beckman Coulter) and XE-2100 (Sysmex) automated hematology analyzers. The sum of the manual counts by a hematology technician and a resident were used as the manual counts. RESULTS: The total analysis time and hands-on time required by the Hematoflow method were shorter than those required by manual counting. Hematoflow counts were reproducible, showed a good correlation with automated analyzers, and also showed strong correlation with manual counts (r > 0.8) in neutrophils, lymphocytes, and monocytes. None of the cases containing less than 4% blasts as analyzed by the Hematoflow method had blasts in the manual counts, but 8 cases of 21 cases (38.1%) with over 4% blasts by Hematoflow had blasts in manual counts. CONCLUSION: Hematoflow counts of severely leukopenic samples were reproducible and showed a good correlation with manual counts in terms of neutrophil, lymphocyte, and monocyte counts. The Hematoflow method also detected the presence of blasts. Manual slide review is recommended when over 4% blasts are found by Hematoflow.
