Spectrum of Hemophagocytosis in Bone Marrow Aspirates: Experience from a Tertiary Care Hospital in North India.

Background: Hemophagocytosis refers to the engulfment of hematopoietic cells by histiocytes. It can be seen in various conditions but is usually reported in the setting of hemophagocytic lymphohistiocytosis (HLH). Optimal interpretation of hemophagocytosis in the bone marrow in relation to the underlying disease significantly contributes to correct patient management.

Detection of focal lesions in the clot section with negative bone marrow aspirate and trephine biopsy-A series of 5 cases.

Bone marrow aspiration and trephine biopsies are commonly used procedures in clinical practice. The practice of making a clot section by using the leftover blood from the bone marrow aspirate material is not a commonly followed practice across centers. A clot section has the advantage of studying the added material with an increased possibility of detecting focal lesions such as myeloma, lymphoma, granuloma, and metastasis in the bone marrow.

Macrothrombocytopenia: Role of Automated Platelet Data in Diagnosis.

Purpose: Inherited macrothrombocytopenia is an underdiagnosed condition and may result in misdiagnosis and inappropriate management. This research was done to study this condition in a hospital setting.

Materials And Methods: This study was conducted over 6 months in a teaching hospital.

Psychological implications of Covid-19 in healthcare workers.

Background: The Covid-19 outbreak has led to an unprecedented burden on the healthcare infrastructure. High morbidity and mortality rates have resulted in a state of stress and distress among the general population which has also impacted health professionals.

Aims: This study was conducted to identify mental health disturbances among health professionals during the Covid-19 pandemic.

Role of Automated Volume, Conductivity and Scatter (VCS) Parameters of Neutrophils as Indicators of Sepsis.

This study was done to evaluate the role of automated volume, conductivity and scatter (VCS) parameters of neutrophils as indicators of sepsis and its differentiation from other inflammatory disorders. In this cross-sectional study, 225 patients with culture proven or with clinical evidence of sepsis were included along with an equal number of healthy controls. In addition, 138 patients with non-infective inflammatory conditions-acute pancreatitis (50), burns (45) and acute myocardial infarction (43) were also included.

Screening chronic myeloid leukemia neutrophils using a novel 3-Dimensional Spectral Gradient Mapping algorithm on hyperspectral images.

Background and objective Early diagnosis of chronic myeloid leukemia (CML) is important for effective treatment. The high spectral and spatial resolution of hyperspectral cellular or tissue images coupled with image analysis algorithms may provide avenues to detect and diagnose diseases early. Many algorithms have been used to analyze medical hyperspectral image data, each having their own strengths and short-comings.

A Comparative Study of Bone Marrow Squash and Wedge Aspiration Smears.

Bone marrow examination entails study of aspirate smears, touch imprints and trephine biopsy. Bone marrow aspirate smears can be prepared by the squash (crush) or wedge method. Both techniques have their own advantages and disadvantages.

Disseminated Cryptococcosis in a Young Immunocompetent Male.

Cryptococcosis is an opportunistic infection caused by encapsulated yeasts of genus Cryptococcus. It usually infects immunocompromised patients and has multisystemic involvement, the common sites being lungs, central nervous system, skin and bone marrow. Disseminated cryptococcosis has also been reported in immunocompetent individuals.

Chronic neutrophilic leukemia presenting as secondary gout: Report of a rare myeloproliferative disorder.

Chronic neutrophilic leukemia is a rare leukemia seen in middle aged and elderly people, characterized by neutrophilic leukocytosis with no significant increase in granulocytic precursors. The chief criteria for diagnosis include total leukocyte count ≥25 × 109/L, >80% of white blood cells being mature neutrophils (segmented and band forms), immature granulocytic precursors ≥10% in the peripheral blood, and hypercellular marrow. In addition to this, there must be no evidence of dysplasia, monocytosis or BCR-ABL1, PDGFR-A, PDGFR-B, or FGRF-1 rearrangements.

Hb Rush (: c.304G>C): A Rare Variant Hemoglobin Mimicking the Hb S (: c.20A>T) Variant on High Performance Liquid Chromatography.

High performance liquid chromatography (HPLC) is a useful and rapid tool in the evaluation of hemoglobin (Hb) disorders that include thalassemia and various hemoglobinopathies. Most of the techniques or programs used in automated testing platforms are customized to identify the common variants seen in that particular region. At times, variant Hbs may be identified which are not commonly seen in the local population.

Comparison of Rapid Centrifugation Technique with Conventional Centrifugation for Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) Testing.

Prothrombin Time (PT) and activated partial thromboplastin time (APTT) are frequently performed coagulation tests in patients with coagulation disorders especially in critical care areas and in monitoring patients on anticoagulation therapy. In coagulation testing, sample processing especially centrifugation is one of the most critical steps that affect turnaround time (TAT). This study was carried out over a period of 1 year.

Unrelated and related donor transplantation for beta-thalassemia major: A single-center experience from India.

Hematopoietic stem cell transplantation (HSCT) remains the only curative treatment in patients with β-thalassemia major. A matched sibling or a related donor is usually found in only 25%-30% of the patients. There are limited data on matched unrelated donor (MUD) transplants from India.

Clinico-Hematological Profile of Hb Q India: An Uncommon Hemoglobin Variant.

Inherited hemoglobin disorders include thalassemias and structural variants like HbS, HbE, and HbD, Hb Lepore, HbD-Iran, Hb-H disease and HbQ India. HbQ India is an uncommon alpha-chain structural hemoglobin variant seen in North and West India. Patients are mostly asymptomatic and often present in the heterozygous state or co-inherited with beta-thalassaemia.

Lower Total Leukocyte and Neutrophil Counts in Healthy Young Africans from Uganda.

The total leukocyte count (TLC) is an important component of the complete blood count and influences many clinical decisions. The effect of race or ethnicity on TLC is not well known. The African population has been reported to have lower than normal TLC and neutrophil counts.

Un-manipulated Haploidentical Transplant in Wiskott-Aldrich Syndrome.

Background: Allogeneic stem cell transplant is the only curative treatment for Wiskott-Aldrich syndrome.

Case Characteristics: 18-months-old boy with no sibling, cord blood or matched unrelated donor transplant options.

Outcome: Doing well 7 years after haplo-identical stem cell transplantation using unmanipulated bone marrow as the stem cell source.

Hemophagocytosis by Leukemic Blasts in T Cell Acute Lymphoblastic Leukemia: An Unusual Finding.

Hemophagocytosis shows engulfment of hematopoietic cells by histiocytes and is a property generally associated with cells of the histiocytic lineage. It can be familial or is seen in a wide spectrum of acquired disorders. Hemophagocytosis by leukemic blasts is an uncommon phenomenon and has been reported mainly in acute myeloid leukemia.
