BACKGROUND Infection or colonization with multidrug-resistant organisms (MDRO) is associated with high mortality and morbidity. Knowledge of MDRO colonization may help in planning empirical antibiotic approach in neutropenic patients, which is known to improve patient outcomes. While routine cultures are positive and may help direct antibiotic therapy in(More)
We document the characteristics of BCR-ABL kinase domain mutations (KDM) in the largest study from India comprising of 385 patients and demonstrate that more than half (51.9%) of these patients have detectable abnormalities in the KD both in adult and in pediatric chronic myelogenous leukemia (CML). These comprise singly occurring missense mutations(More)
A spurt of cases of Neurocysticercosis (NCC) at our department reopened the debate on whether to treat or not and spurred us on to review the available literature for a viable solution. Despite the disease having been around for centuries a cogent treatment plan eludes us even as other ancient scources have been successfully engaged. Neurocysticercosis(More)
Congenital rhabdomyosarcomas (RMSs) are rare tumors with variable clinical presentations. A 2 month-old, term male neonate (37 weeks, 4 days), weighing 3.2kg, born to a 24 year-old primigravida, by simple vaginal delivery presented with multiple erythematous papulonodular lesions over his trunk that progressed to his whole body, on the first day of(More)
X-linked agammaglobulinemia (XLA) is a rare disorder in which recurrent infections occur due to low serum globulins and circulating B lymphocytes caused by a mutation in the Bruton tyrosine kinase (Btk) gene. While myelodysplastic syndrome (MDS) associated with low B lymphocyte counts has been described, clonal cytogenetic abnormalities in confirmed cases(More)
CONTEXT Langerhans cell histiocytosis (LCH) is a rare atypical cellular disorder characterized by clonal proliferation of Langerhans cells leading to myriad clinical presentations and highly variable outcomes. There is a paucity of Indian studies on this subject. AIM To present the experience of management of LCH at a single institution. SETTINGS AND(More)
BACKGROUND Survivors of childhood cancer are at increased risk for several cardiometabolic complications. Obesity/overweight and metabolic syndrome have been widely reported in Western literature, but data from India are lacking. AIMS To perform an objective assessment of nutritional status in a cohort of childhood cancer survivors (CCSs) and to find risk(More)
BACKGROUND Blood stream infections (BSI) are among the most common causes of preventable deaths in children with cancer in a developing country. Knowledge of its etiology as well as antibiotic sensitivity is essential not only for planning antimicrobial policy, but also the larger infection prevention and control measures. AIMS To describe the etiology(More)
BACKGROUND In children, innate and adaptive immunity varies with age, disease status, and ethnicity, reflected by lymphocyte subsets and serum immunoglobulin (Ig) levels. The paucity of such data from the Indian subcontinent necessitated this study. AIMS This study aims to determine reference ranges of Ig and lymphocyte subsets in Indian children from(More)
BACKGROUND Multiparametric flow cytometry (MFC) is a popular technique for minimal residual disease (MRD) analysis. However, its applicability is still limited to 90% of B-cell precursor acute lymphoblastic leukemia (BCPALL) due to two major issues, i.e. a proportion of cases do not express adequate leukemia associated immunophenotype (LAIPs) with currently(More)
