Article Synopsis
  • Nearly 90% of children and adolescents with Hodgkin lymphoma (HL) survive long-term, but about 5-30% may experience either refractory disease or relapse after initial treatment.
  • A study at Indus Hospital analyzed 742 HL patients between 2013 and 2022, finding that 6.5% had relapsed and 4.7% were refractory, with a majority being diagnosed at stage IV and having a common pathology of nodular sclerosis.
  • After second-line treatment, 70.8% of relapsed patients achieved complete remission, but significant treatment challenges persist in low-resource settings, including a lack of immunotherapy and stem cell transplants.

Introduction: Craniopharyngioma constitutes approximately 10% of primary brain tumors in children. It can cause considerable morbidity and mortality due to the local aggressiveness of the tumor itself or its management affecting the hypothalamus-pituitary axis and optic pathway involvement. There is very scarce data available from LMIC which makes the management controversial where multidisciplinary teams are already not available in most of the centers.

Medulloblastoma is the most common malignant brain tumour in children and is a major cause of mortality and morbidity, particularly in low- and middle-income countries. It has been risk-stratified on the basis of clinical (age, metastasis and extent of resection) and histological subtypes (classic, desmoplastic and anaplastic). However, recently medulloblastoma has been sub-grouped by using a variety of different genomic approaches, such as gene expression profiling, micro-ribonucleic acid profiling and methylation array into 4 groups, namely Wingless, Sonic hedgehog, Group 3 and Group 4.

Background: The recent pandemic by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global emergency. There is large number of asymptomatic cases of SARS-CoV-2 that are not reported. Hence, serological evidence of SARS-CoV2 antibodies is warranted for a better estimation of the actual number of infected patients to limit the disease spread and to get an idea of herd immunity.

Objective: Brain tumors are the second most common pediatric malignancy and the most common cause of cancer-related mortality and morbidities. Major advances in terms of surgery, radiation, and chemotherapy have led to better outcomes in developed countries. Delayed diagnosis, advanced disease at presentation, late referrals, nosocomial infections, delays to radiotherapy, and poor support services are the major reasons for poorer outcomes in developing countries.

Introduction: Primitive myxoid mesenchymal tumor of infancy (PMMTI) is a recently diagnosed entity, with only a handful of cases reported to date.

Case Description: Herein, we present the occurrence of this tumor in a 2-year-old boy, initially diagnosed as primitive neuroectodermal tumor of the extremity and treated with chemotherapy and surgical resection. He later presented with a cerebellar lesion, and biopsy was consistent with PMMTI.

The aim of this study was to assess the frequency of VAP(ventilator associated pneumonia) after strict implementation of ventilator bundle in PICU. Medical records of all children (age 1 month - 16 years) were retrospectively reviewed, who were on mechanical ventilation (MV) for more than 48 hours and received all key components of "ventilator bundle" from January 2012 to December 2014. Out of 1050, 565 (54%) patients were enrolled.
