Objective:To audit the usage of fresh frozen plasma (FFP) and to study the effect of FFP on the pre-transfusion international normalized ratio (INR).Materials and Methods:Medical records of 100 consecutive patients who received FFP in our institute were retrospectively studied. FFP usage was classified as appropriate or inappropriate based on the guidelines by the National Health and Medical Research Council and The Australasian Society for Blood Transfusion. Pre-and post-transfusion INR were recorded and the effect of FFP on the pre-transfusion INR was studied in patients who appropriately received FFP. Relationship between the pre-transfusion INR and improvement in the INR per unit of FFP was studied using Pearson’s correlation.Results:Total 325 units were issued for the 100 patients (37 males and 63 females, mean age 33 years, range 1-65 years). Obstetrics and gynecology and medicine departments requested most units of FFP. Total 197 units (60.6%) in 67 patients were appropriately transfused and 128 units (39.4%) in 33 patients were inappropriately used. Mean improvement in the pre-transfusion INR per unit of FFP was 0.79 (median 0.53, range 0-3.5, SD 0.94). A significant improvement in the pre-transfusion INR per unit of FFP was seen in 64.9% patients. A linear relationship was noted between the pre-transfusion INR and improvement in INR per unit of FFP (r=0.89, degree of freedom 55).Conclusion:Proportion of inappropriate FFP usage remains high. A significant improvement in INR is more likely with a high pre-transfusion INR. The improvement in INR per unit of FFP is also more with higher pre-transfusion INR.
Pure ovarian choriocarcinoma is extremely rare and can develop as a germ cell tumor or as a metastasis from uterine or tubal gestational choriocarcinoma or rarely from an ovarian pregnancy. The cytomorphologic findings have been reported previously in different sites. However, this is the first case of pure ovarian choriocarcinoma diagnosed on cytology to the best of our knowledge. The distinction between a gestational and nongestational choriocarcinoma is difficult. A 19-year-old female patient presented with an irregular per-vaginal bleeding and a mass in lower abdomen. Fine needle aspiration cytology smears of the mass were hypocellular and showed large, multinucleated giant cells and malignant mononucleated cells. Background was hemorrhagic. Serum beta hCG level was 3,80,000 mIU/ml. A diagnosis of choriocarcinoma was offered which was later confirmed by histopathology. The diagnosis of choriocarcinoma on fine needle aspiration cytology is based on the presence of large, multinucleated giant cells and malignant mononucleated cells. A high index of suspicion should be maintained and estimation of serum beta hCG plays a key role in supporting the diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
