Article Synopsis
  • Acute encephalitis syndrome (AES) in children is a major health issue in India, and this study evaluates the role of inflammatory mediators and neurofilament (NfL) levels in differentiating the causes, understanding disease severity, and predicting outcomes in AES.* -
  • The research analyzed serum and cerebrospinal fluid (CSF) samples from 62 children with AES, finding that markers differed significantly among scrub typhus, viral infections, and COVID-related multisystem inflammatory syndrome (MIS-C), with specific levels of cytokines revealing patterns that aid in diagnosis.* -
  • The study concluded that certain serum markers could effectively differentiate between scrub typhus and other types of AES, and higher levels of certain

Background: Continuous positive airway pressure (CPAP) has been used in children with bronchiolitis for a long time. Currently in the low-resource settings, the method of providing oxygen therapy via bubble CPAP (bCPAP) to children with respiratory distress is not standardized and the existing low-flow oxygen therapy has a high mortality rate.

Objectives: To study the effectiveness and safety of bCPAP as a respiratory support in children with respiratory distress.

Article Synopsis
  • The study aimed to evaluate the impact of two fluid resuscitation methods—balanced crystalloid (MES) and 0.9% saline—on kidney function in children with septic shock.
  • Conducted in pediatric intensive care units across India from 2017 to 2020, the trial involved 708 children under 15 who were randomly assigned to receive either MES or saline for the first week of treatment.
  • Results showed that those receiving MES experienced a significantly lower rate of acute kidney injury compared to saline (21% vs. 33%), while there was no significant difference in ICU mortality between the two groups.

  • - Scrub typhus, caused by Orientia tsutsugamushi, is recognized as a significant contributor to acute encephalitis syndrome (AES) in northern India, and this study examined its impact in southern India by diagnosing 376 children with AES.
  • - Among the children tested, scrub typhus was diagnosed in 87 (23%), with varying degrees of association to AES: confirmed in 16, probable in 55, and possible in 16 cases.
  • - The study found that IgM detection in cerebrospinal fluid (CSF) is a reliable diagnostic tool, showing a 93% sensitivity and an 82% specificity, underscoring the need for routine testing for scrub typh

Background: Acute respiratory distress syndrome (ARDS) is characterized by dysregulated inflammation resulting in hypoxemia and respiratory failure and causes both morbidity and mortality.

Objectives: To describe the clinical profile, outcome, and predictors of mortality in ARDS in children admitted to the Pediatric intensive care unit.

Materials And Methods: This is a single-center retrospective study conducted at a tertiary referral hospital in a 12-bed PICU involving children (1 month to 18 years) with ARDS as defined by Pediatric Acute Lung Injury Consensus Conference (PALICC) guidelines, over a period of 5 years (2016-2020).

Objective: To describe the occurrence, microbiology, and risk factors of catheter- associated urinary tract infections (CA-UTI) in critically ill children.

Methods: We conducted a review of hospital records for CA-UTI in the pediatric intensive care unit (PICU) over a 7-year period (2014-2020).

Results: 62 CA-UTI cases (48% boys, median (IQR) age 36 (12,96 month) were identified during the study period with occurrence rate of 7.

Peritoneal dialysis (PD) is a simple and preferred modality of dialysis for children with acute kidney injury (AKI) in resource poor countries. The aim of the study is to evaluate the utility and safety of acute PD using rigid catheter in critically ill children admitted to pediatric intensive care unit (PICU) with emphasis on short-term patient and renal outcome and complications. In this retrospective study, outcome and complications of PD using rigid catheter were evaluated in 113 critically ill children admitted in PICU of a tertiary care hospital from 2014 to 2019.

There is a paucity of literature on the prevalence, predictors, prognostic markers, and outcomes of sepsis-induced myocardial dysfunction (SMD) in pediatric septic shock. The objectives of our study were to estimate the prevalence of SMD in pediatric septic shock by point-of-care functional echocardiography (POCFE) and to study the association of SMD with severity of illness, organ dysfunctions, and outcomes. This prospective, observational study was conducted over a period of 1 year (from July 2018 to July 2019) in a 12-bed, tertiary pediatric intensive care unit (PICU) of an academic and referral hospital in South India.

Objective: To describe the clinical profile and outcome of emergencies in children with chronic kidney disease (CKD).

Methods: This retrospective analysis studied children with CKD presenting with acute emergencies. The clinical profile, renal and patient outcomes were compared between incidentally diagnosed - iCKD, previously diagnosed not on dialysis - pCKD and those on maintenance dialysis - dCKD groups.

Background: Isolated and predominant gastrointestinal presentation in coronavirus disease 2019 (COVID-19) is reported less often. With evolving evidence that gastrointestinal tract can be a portal of entry, multiplication, primary site of affliction and symptomatic manifestation, and source of infectivity through prolonged fecal shedding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), it is essential that isolated gastrointestinal symptoms can also be a mode of presentation of this novel virus and illness.

Case Description: The index case is a 10-year-old female child who presented with acute onset abdominal pain.

Unlabelled: Extrapulmonary tuberculosis (TB) involving bone marrow can present with various manifestations, including pancytopenia, maturation arrest, hemophagocytic lymphohistiocytosis (HLH), or infiltration of the bone marrow by caseating or noncaseating granulomas causing reversible or irreversible fibrosis. Tumor lysis syndrome (TLS) is an oncologic emergency resulting from massive tumor cell lysis. Children with TB with bone marrow involvement may also present with laboratory features of TLS resulting from high catabolism and concomitant acute kidney injury (AKI), making the diagnosis difficult at times.

Unlabelled: There is a global variation in policies that define clear indications for pediatric intensive care unit (PICU) admissions. In resource-limited countries where PICU service availability is limited, the admission criteria to PICU are urgently needed to optimize the utilization of available intensive care services and to maximize patient benefit. The objective of these consensus recommendations on PICU admission criteria is to provide a framework and reference for future policy development by professional societies and governments.
