This report describes an interesting autopsy case of a 62-year-old lady presenting with itching and stroke-like symptoms.

Clinical and Prognostic Impact of Copy Number Alterations and Associated Risk Profiles in a Cohort of Pediatric B-cell Precursor Acute Lymphoblastic Leukemia Cases Treated Under ICiCLe Protocol.

Copy number alteration (CNA) status and CNA risk profiles of , UK-ALL CNA risk groups and MRplus scores, were evaluated for clinical and prognostic impact in a cohort of 493 B-cell acute lymphoblastic leukemia cases diagnosed and treated under the Indian Collaborative Childhood Leukemia group (ICiCLe) protocol trial. Overall CNA frequency was 59% with 60% of cases showing 2-loci deletion. deletion was most common CNA (36.

Clinico-hematological and Outcome Profile of Pediatric B-other-ALL and BCR::ABL1-like pre-B-ALL: An Integrated Genomic Study From North India.

Purpose: BCR::ABL1-like pre-B-ALL comprises a myriad of genetic lesions making molecular diagnosis challenging and expensive. Its frequency and outcome are less studied in resource-constraint settings.

Methods: 154 pre-B-ALL cases (0-12 years) were enrolled as group 1 (37 cases of B-other-ALL) and group 2 (117 patients with recurrent translocations/ hyperdiploidy).

Randomized controlled trial of individualized, low dose, fixed duration lenalidomide maintenance versus observation after frontline chemo-immunotherapy in CLL.

Lenalidomide maintenance after frontline chemo-immunotherapy (CIT) in chronic lymphocytic leukemia (CLL) has not been standard due to the availability of novel therapies, though these remain out of reach for most in low-middle income countries. This single-center, open-label study randomized CLL patients (non-deletion 17p) after frontline therapy to lenalidomide maintenance (dose-escalated 2.5-10mg, 20/28 days per cycle for six months) or observation (2:1 allocation).

Chronic Lymphocytic Leukemia: Real-World Data From India.

Purpose: Chronic lymphocytic leukemia (CLL) is uncommon in India. There are limited studies on CLL from the Indian subcontinent.

Methods: This was a prospective study (2011-2017) of consecutively diagnosed patients with CLL at a single center.

Role of Granulocyte Colony Stimulating Factor on the Short-Term Outcome of Children with Acute on Chronic Liver Failure.

Background: Acute-on-chronic liver failure (ACLF) results in very high mortality in children. We aimed to evaluate the role of granulocyte colony-stimulating factor (GCSF) on short-term outcome of children with ACLF in a nontransplant unit.

Methods: Children (aged > 1 year) diagnosed with ACLF over a 15 month period were randomised.

PEST domain NOTCH mutations confer a poor relapse free survival in pediatric T-ALL: Data from a tertiary care centre in India.

A comprehensive genotype-phenotype analysis of pediatric T-ALL data was performed. 33 confirmed pediatric (≤12 y) T-ALL samples were evaluated for oncogenic transcripts: TLX-1, TLX-3, common fusion of STIL-TAL1, NOTCH1 mutations and copy number variations (CNVs). Mean WBC was 235.

Screening for paroxysmal nocturnal hemoglobinuria (PNH) in patients presenting with cerebral sinovenous thrombosis (CSVT): Results of a FLAER based flowcytometry study in Indian patients.

Patients with paroxysmal nocturnal hemoglobinuria (PNH) may present with thrombosis at unusual sites, of which cerebral sinovenous thrombosis (CSVT) is one and screening for PNH is recommended in this condition. Though many patients diagnosed with PNH develop CSVT, it is unclear how many patients with PNH would present for the first time with thrombosis. We analysed the results of screening for PNH by flowcytometry in our patients with CSVT.

Low Expression of Leucocyte Associated Immunoglobulin Like Receptor-1 (LAIR-1/CD305) in a Cohort of Pediatric Acute Lymphoblastic Leukemia Cases.

Background: Immunophenotypic markers can play significant role in prognostic assessment for different cancers and leukocyte-associated Ig-like receptor (LAIR-1) is a recently identified inhibitory immuno-receptor. Methods: We measured LAIR-1 expression in paediatric ALL patients (n-42) and appropriate controls by flow cytometry. Median fluorescence intensities (MFIs) were calculated and correlated with demographic and clinical variables and early treatment outcome parameters.

Deletion of CDKN2A/B is associated with inferior relapse free survival in pediatric B cell acute lymphoblastic leukemia.

Considering conflicting data on CDKN2A/B deletion in ALL, this study to assess its prognostic significance as an independent marker in a total of 96 pediatric B and T-ALL cases was planned. The overall frequency of CDKN2A/B deletion was 44% (n = 43) with 36% (30/83) in B-ALL and 100% (13/13) in T-ALL. CDKN2A/B deletion was significantly associated with high WBC count (p = .

Optimal Reference Gene Selection for Expression Studies in Human Reticulocytes.

Reference genes are indispensable for normalizing mRNA levels across samples in real-time quantitative PCR. Their expression levels vary under different experimental conditions and because of several inherent characteristics. Appropriate reference gene selection is thus critical for gene-expression studies.

High frequency of intermediate and poor risk copy number abnormalities in pediatric cohort of B-ALL correlate with high MRD post induction.

Copy number abnormalities (CNAs) and recurrent fusion transcripts are important genetic events which define and prognosticate B-Cell Acute Lymphoblastic Leukemia (B-ALL). We evaluated CNAs and fusion transcripts in 67 pediatric B-ALL cases and correlated the data with standard risk factors and early treatment outcome parameters. Common fusion transcripts ETV6-RUNX1, E2A-PBX, BCR-ABL1 and MLL-AF4 were examined by RT-PCR and noted in 15%, 15%, 13% and 1.

CLL: Common Leukemia; Uncommon Presentations.

We report here a series of ten patients with uncommon presentations and associations of chronic lymphocytic leukemia (CLL) not reported hitherto or occasionally reported in literature. The first two cases describe unusual causes of abdominal distension in CLL and unusual sites infiltration by CLL. The next two cases illustrate occurrence of CLL in association with other hematological malignancies.

T-cell/Natural killer-cell neoplasms presenting as leukemia- Case series from single tertiary care center.

Background: Mature T/ NK-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. Most of the previous studies have focused on mature B-cell lineage leukemias and there is a paucity of data on mature T/NK-cell lineage leukemias. We, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features.

Chronic Lymphocytic Leukemia With Hodgkin and Reed-Sternberg (HRS) Cells: A Potential Diagnostic Pitfall in Lymph Node Biopsies.

Chronic lymphocytic leukemia (CLL) is known to undergo Richter transformation in a proportion of cases. Transformation into Hodgkin lymphoma has been described in a minority of the cases. However, CLL rarely also shows Hodgkin and Reed-Sternberg cells with a classic morphology and the immunophenotype of Hodgkin lymphoma, even when not in transformation.

Hypereosinophilia in Acute Lymphoblastic Leukemia: Two Cases with Review of Literature.

Eosinophilia is rare in acute leukemia at presentation. Discrete reports and case studies in recent years have created significant interest in the field of "Acute leukemia with eosinophilia". We herein present two cases of eosinophilia in association with acute lymphoblastic leukemia with brief review of literature in this field.

Epstein-barr virus infection masquerading as acute leukemia: a report of two cases and review of literature.

Epstein-Barr virus (EBV) is the first herpes virus to be completely sequenced. It is implicated in diseases from the benign infectious mononucleosis to malignant nasopharyngeal carcinoma, Burkitt's lymphoma and primary CNS lymphoma in AIDS patients. It has also been found to be associated with some miscellaneous diseases like chronic fatigue syndrome, multiple sclerosis etc.

Clozapine associated thrombocytopenia.

Although agranulocytosis as a side effect of clozapine is well known, there is scarcity of data with regard to thrombocytopenia associated with clozapine. In this report we describe a case of clozapine induced thrombocytopenia and review the existing literature. A 22 year old female patient developed thrombocytopenia while on clozapine 187.

Light chain proximal tubulopathy without crystals in a case of Burkitt lymphoma presenting with acute kidney injury.

Acute kidney injury is a common manifestation of malignancies, either directly by the tumor or indirectly from anticancer therapy. The pathologic correlates of acute kidney injury in malignancies are many and can be diagnosed conclusively using kidney biopsy. We report a rare case of a patient with light chain proximal tubulopathy without crystals who presented with acute kidney injury.

Hepatosplenic T-cell lymphoma is a distinct rare entity: diagnosis by fine-needle aspiration cytology.

In this brief report, we have described the fine-needle aspiration cytology (FNAC) of a hepatosplenic T-cell lymphoma (HSTCL) in a 60-year-old female patient. The patient complained of fever and heaviness of left upper abdomen. Ultrasound-guided FNAC of the spleen showed immature lymphoid cells, and a diagnosis of primary non-Hodgkin lymphoma of spleen was offered.

Adverse impact of pretransplant polyoma virus infection on renal allograft function.

Background: BK polyoma virus (BKV) has emerged as an important cause of acute and chronic allograft injury in renal transplant recipients. Reactivation of latent infection requires reduction in cell-mediated immunity. We hypothesized that BKV could get reactivated in the urinary tract of patients with end-stage renal disease (ESRD) and impact the allograft function after these individuals undergo transplantation.
