Notes

Retraction can be 'second extinction' pertaining to uncommon old.
Although not statically significant this may be considered as one of the contributory risk factors for the development of DVT. A larger study is required for the validation of data. © Indian Society of Hematology and Blood Transfusion 2019.Hematomas in close compartments and in pelvic gutters are always challenging to treat and diagnose. A young female on apixaban for recently diagnosed pulmonary thromboembolism (PE) presented to us for the complaints of right sided lower limb weakness. Neurological examination was positive for the right femoral nerve distribution deficit. Computed tomography (CECT) showed large right sided iliopsoas hematoma. Anticoagulation was stopped and was given blood transfusions with which she improved without need of any surgical evacuation. We hereby aim to enrich the understanding of our readers regarding this topic with a review of our experience and other recent publications in medical literature. It is important for the internists to be aware of varied and atypical presentations of retroperitoneal hematoma (RPH) especially following surgical/orthopaedic procedures or in association with anticoagulants and antiplatelets. © Indian Society of Hematology and Blood Transfusion 2019.Pseudothrombocytopenia is an ex vivo EDTA-dependent artefactual thrombocytopenia, that has been described in association with several conditions. When EDTA-blood samples are drawn from patients with pseudothrombocytopenia and analysed by automated cell counters, low platelet counts are obtained (often below 50,000/mm3). However, simultaneous heparinised samples show normal platelet counts, and peripheral smears show no reduction in numbers of platelets. We report a series of 12 patients with scrub typhus infections and pseudothrombocytopenia. An association between these two entities has only recently been appreciated. It appears that pseudothrombocytopenia may sometimes accompany acute scrub typhus infections. The distinction between pseudothrombocytopenia and true thrombocytopenia is of great clinical relevance, as the former is merely a laboratory artefact, and does not require blood product transfusions despite apparently severe reductions in platelet counts. It is therefore important to recognise that apparent thrombocytopenia, especially in patients with an acute febrile illness due to scrub typhus, is not always true thrombocytopenia. © Indian Society of Hematology and Blood Transfusion 2019.The present study aimed to investigate the clinical effects of the brand new perioperative transfusion trigger score (POTTS) system in patients undergoing malignant tumor surgeries. 442 cases of patients diagnosed with malignant tumor were randomly selected (from January 2012 to December 2016) from Zunyi Medical University and were divided into 3 experimental groups. Patients in the POTTS group were transfused by the POTTS guideline perioperatively, while patients in the 7-10 g group were treated by the traditional transfusion guidelines existed (restrictive transfusion strategy), patients in the 10 g group should be transfused to keep the Hb level no less than 10 g/dL (liberal transfusion strategy). Baseline information, operation time, bleeding volume, transfusion amount, incision healing time, postoperative complications, metastasis and recurrence were observed and recorded. Postoperative short-term mortality was comparable of the 3 groups, 3 cases of death all occurred in 10 g group, there was no significant difference in the incidence of postoperative complications, including infectious complications and coagulation related complications. Follow-up to date, there were 25 cases, 29 cases and 29 cases of tumor recurrence and metastasis in the three groups, but no statistical difference observed. The present findings show that the POTTS transfusion system is more advantageous with regard to save blood and relieve economic burdens of patients, and does not affect the long-term recurrence and metastasis rate of malignant tumor. © Indian Society of Hematology and Blood Transfusion 2019.Safe blood transfusion is the primary need of all the health care delivery system. Though with the advances of transfusion medicine, the incidences of transfusion risk is gradually reduced, but the adverse transfusion reaction (ATR) of non hemolytic type still prevails. The purpose of this study was to estimate the incidence and pattern of transfusion-related adverse events at our centre. The present retrospective observational study was conducted in the Department of Transfusion Medicine from April 2011 to April 2018, at a multi-organ transplant centre in South India. All the Adverse transfusion reactions were investigated in detail in the blood bank for the clerical errors, immunohematology workup and classified according to their nature with imputability assessment. A total of 140 ATR were reported out of 100,569 blood components distributed during the study period. After the analysis and workup of the reported reactions, majority of the reactions were observed in males (71%, n = 99). Most common symptom presented was Itching/Rashes in 43.6% (n = 61) ATR. Allergic reactions (51.4%, n = 72), were the most commonly encountered ATR followed by FNHTR (25.7%, n = 36). FFP transfusions (0.2%) contributed to the majority of the reactions followed by Red cell transfusion (0.15%). Y-27632 in vivo ATR were observed maximum in Hepato-biliary disease and liver transplantation patients (62%) followed by oncology patients (15%). The overall incidence of ATR in our study is 0.14% which is comparatively low compared to other studies due to well established hemovigilance systems. Adoption of more equipped methods & sensitive technology in various areas of blood banking will help to bring down the unwanted adverse transfusion reactions. © Indian Society of Hematology and Blood Transfusion 2019.Blood transfusion is an indispensable part of modern medical and surgical practices. More than 35% of critically ill patients receive transfusion of blood components during their intensive care unit stay. The aim of study is to obtain an information regarding the relationship of platelet concentrate (PC) and fresh frozen plasma (FFP) transfusion on clinical outcome of neonates admitted in neonatal ICU (NICU). This prospective cohort study was conducted from 1st November 2011 to 30th April 2013. The clinical history, blood component details and laboratory parameters were evaluated with clinical outcome. The neonates requiring PC and FFP transfusion were followed up in blood bank for laboratory parameters. Clinical parameters were noted from case file. During the study period, 291 neonates were admitted in NICU. 2 neonates had congenital malformations and thus, were excluded from the study. Of the remaining 289 neonates, 49 neonates received transfusion of platelets and/or FFP. The combined mean donor exposure for all components was found to be 1.
