Methods: It was a cross-sectional study conducted at the department of Hematology and Transfusion Medicine, University of Child Health Sciences, The Children's Hospital, Lahore from October 2022-January 2023. A self-designed questionnaire was used to assess the baseline knowledge of students followed by educational interventions in the form of small group discussions, video lectures and practical demonstrations.

Prevalence of A2 and A2B Subgroups among Blood Groups A and AB in healthy donors.

Objective: To determine the frequency of A2 and A2B subgroups among blood groups A and AB in healthy donors.

Methods: It was a Cross-Sectional study, conducted at the Department of Hematology & Transfusion Medicine, UCHS, The Children's Hospital Lahore and Sundas foundation Lahore from June 2022 to December 2022 including 13,120 healthy blood donors of both genders, after taking informed consent. Venous blood samples of donors were collected in EDTA vials (3ml) and serum gel vial for routine blood grouping which was done by standard tube method.

Complications of Therapeutic Plasma Exchange in pediatric patients: An experience at a tertiary care hospital.

Objective: To find the incidence of various complications of therapeutic plasma exchange (TPE) in ICU admitted children and to determine their association with age, gender, blood group and diagnosis of the patients.

Methods: In this observational study, data of 24 patients who underwent 125 sessions of TPE was collected from the Pediatric Intensive care unit (PICU) and Hematology department of The Children's Hospital, Lahore from December 2020 to November 2021. Age, gender, blood group, indications and complications observed during and after the TPE procedure were documented on a pre-designed proforma.

Comparison of single and double centrifugation methods for preparation of Platelet-Rich Plasma (PRP).

Objective: To compare the platelet count, platelet concentration/yield, residual Red blood cells (RBCs) and White blood cells (WBCs) counts in platelet-rich plasma (PRP) samples prepared from the single- and the double-centrifugation protocols.

Methods: It was a Cross-Sectional study, conducted at the Department of Hematology & Transfusion Medicine, The Children's Hospital and UCHS, Lahore from October 2021 to January 2022 including 50 voluntary, healthy individuals of age 20-45 years of both genders, after taking informed consent. Complete blood count analysis of all participants was done initially by drawing 3ml blood in EDTA vial.

Effect of donor and red blood cells concentrate characteristics on recipient hemoglobin increment following red blood cells transfusion in pediatric patients.

Objectives: To determine the effects of donor and red blood cells concentrate characteristics on recipient hemoglobin increment following red blood cells transfusion in pediatric patients.

Methods: This cross-sectional study was conducted at The Hematology & Transfusion Medicine Department of The UCHS & The Children's Hospital, Lahore from 23 December 2020 to 31 July 2021 after Institutional Ethical committee approval. After taking informed consent from parents/guardians, One hundred recipients receiving RBCs unit transfusion studied along with the respective donors.

T lymphoblastic lymphoma with BCR-ABL negative chronic myeloid leukaemia: a novel association.

Lymphoblastic lymphoma and chronic myeloid leukaemia (CML) are two distinct neoplasms with different pathogenesis and clinical presentation. We hereby share a challenging case of a child presenting with fever, leucocytosis, generalised lymphadenopathy and massive splenomegaly. He was diagnosed as having novel association of concurrent T-lymphoblastic lymphoma diagnosed on cervical lymph node biopsy with BCR-ABL negative CML on bone marrow aspirate.

Is leukopenia and lymphopenia a characteristic feature of COVID-19 in children?

Objectives: To analyze whether leucopenia and lymphopenia a characteristic feature of children with COVID-19 and to find out its association with the disease severity.

Methods: This was a descriptive cross-sectional study conducted at The Children's Hospital Lahore from March 2020 to October 2020. All confirmed cases of COVID-19 infection and post-COVID MIS-C/Kawasaki Disease diagnosed on the basis of RT-PCR and Antibody test respectively were included.

Characterization of the mutation spectrum in a Pakistani cohort of type 3 von Willebrand disease.

Introduction: Type 3 von Willebrand disease (VWD), a severe autosomal recessive hereditary bleeding disorder, is described by the virtual absence of von Willebrand factor (VWF). In consanguineous populations, for example Pakistan, the disease is reported with a higher incidence rate than the worldwide prevalence.

Aims: This study aims to characterize molecular pathology and clinical profile of type 3 VWD cohort of Pakistani origin.

Correction to: Identification of novel mutations in congenital afibrinogenemia patients and molecular modeling of missense mutations in Pakistani population.

Identification of novel mutations in congenital afibrinogenemia patients and molecular modeling of missense mutations in Pakistani population.

Background: Congenital afibrinogenemia (OMIM #202400) is a rare coagulation disorder that was first described in 1920. It is transmitted as an autosomal recessive trait that is characterized by absent levels of fibrinogen (factor I) in plasma. Consanguinity in Pakistan and its neighboring countries has resulted in a higher number of cases of congenital fibrinogen deficiency in their respective populations.

Atypical Chronic Myeloid Leukemia, BCR-ABL1 Negative, in a 5-Month Baby - ARare Presentation.

Atypical chronic myeloid leukemia (aCML) is a neoplasm with poor prognosis, characterized by myeloid hyperplasia, dysmyelopoiesis and absence of BCR-ABL1 gene. Clinically, the disease course may be similar to chronic myeloid leukemia (CML), BCR-ABL1 positive. It presents in seventh to eighth decade of life with few cases of paediatric aCML being reported.

Congenital amegakaryocytic thrombocytopenia with multiple physical anomalies in a female neonate.

Congenital Amegakaryocytic Thrombocytopenia (CAMT) is a rare disorder of infancy characterized by isolated thrombocytopenia along with hypoplasia or aplasia of megakaryocytes in the bone marrow. It is caused by c-mpl mutation which disrupts the function of thrombopoietin (TPO) receptor. CAMT in association with physical anomalies is a rare entity with only limited data from single case reports being available.
