SpO2/FiO2 and PaO2/FiO2 for Predicting Intensive Care Admission in Wheezy Children: An Observational Study.

OBJECTIVE: To determine the sensitivity of cut-off of SpO2/FiO2 (SF ratio) < 300 at hospital admission for predicting the need for admission in the pediatric intensive care unit (PICU) in wheezy children. Secondary objectives were to determine the sensitivity of cut-off of SF ratio < 300 for predicting in-hospital mortality and that of PaO2/FiO2 (PF ratio) < 200 for predicting intensive care admission and in-hospital mortality. We also ascertained the correlation between SF ratio and PF ratio in the above population. METHODS: This prospective observational study was conducted on 315 wheezy children aged 6 months to 12 years requiring admission in the pediatric emergency department. Oxygen saturation (SpO2) and fraction of oxygen in inspired air (FiO2) were recorded at admission while the partial pressure of oxygen (PaO2) was measured using arterial blood gas analysis performed within half an hour of admission. All children were managed as per protocol and followed up during hospital stay. Outcome was defined as the need for admission in the pediatric intensive care unit (PICU) or in-hospital mortality. RESULTS: Cut -offs of SF ratio < 300 and PF ratio < 200 were able to determine the need PICU admission with a sensitivity of 97.30% and 62.16% respectively. The best cut-off of SF ratio for predicting PICU admission was < 178.79 [AUC (95% CI) 0.841 (0.767, 0.914)], while that for PF ratio was < 201.81 [AUC (95% CI) of 0.849 (0.775, 0.924)]. Cut-offs of < 300 for SF ratio and < 200 of PF ratio, were able to predict in-hospital mortality with sensitivity of 100%, but specificity of only 3.33% and 46.67%, respectively. There was only a moderate correlation between SF ratio and PF ratio (r = 0.44, P < 0.001). CONCLUSION: SpO2/FiO2 cut-off of < 300 had a good sensitivity in determining need for PICU admission. SF ratio has only a moderate correlation with PF ratio.

Carotid Intima-Media Thickness and Metabolic Complications in Children with HIV on Antiretroviral Therapy: A Cross-Sectional Study.

OBJECTIVES: To evaluate carotid intima media thickness (CIMT) in children with Human immunodeficiency virus (HIV) on anti-retroviral therapy (ART) and in controls. Also, to compare body mass index (BMI), body fat percentage, skin-fold thickness (SFT), waist-to-height ratio (WHtR), lipid profile, blood pressure, lipodystrophy syndrome (LDS), non-alcoholic fatty liver disease (NAFLD) in children with HIV and in controls and to determine association between lipid profile, LDS, liver amino-transferases, NAFLD, BMI, body fat percentage, SFT, WHtR and CIMT. METHODS: This cross-sectional study was done in 7 to 12 y old children attending the ART clinic and receiving ART for ≥6 mo according to 2018 National Aids Control Organization (NACO) guidelines. Thirty age and gender matched controls were enrolled from the pediatrics OPD. Weight, height, BMI, waist circumference, skin fold thickness and blood pressure were recorded. Lipid profile, liver amino-transferases, USG abdomen and CIMT were done with prior appointment. RESULTS: The present study had 43% females and 57% males (mean age of 9.33 ± 1.65 y). All cases were on combination ART (mean treatment duration: 59.1 mo). CIMT was significantly increased in cases as compared to controls 0.481 ± 0.087 mm vs. 0.418 ± 0.072 mm (p = 0.003). However, CIMT did not correlate with any other parameter. Cases had significantly higher body fat percentage (17% vs. 13.15%), systolic blood pressure (SBP), SFT, total cholesterol (TC) and low density lipoprotein- cholesterol (LDL-C) as compared to controls. NAFLD was seen in 3 cases (1%), lipohypertrophy in 7 (23%) cases and 5 (16%) controls. CONCLUSIONS: Children with HIV on ART have significantly higher CIMT and increased metabolic abnormalities.

Comparison of Emergency Severity Index Version 4 and Modified Pediatric Early Warning Score as Triage Models in the Pediatric Emergency of a Tertiary Care Public Sector Hospital.

OBJECTIVE: To identify the sensitivity of emergency severity index (ESI) version 4 and modified pediatric early warning score (PEWS) in identifying high urgency patients. METHODS: This cross-sectional study was conducted between November, 2019 and October, 2021 in the pediatric emergency department of tertiary hospital in Delhi. 250 patients aged 0-12 years coming to pediatric emergency on pre-decided days for health-related complaints were enrolled. These were assessed with both triage systems within 30 minutes of their arrival by a single researcher. 'High urgency' patients were defined as the ones who either required admission in pediatric ICU or died or had critical value of vital parameters as per institution protocol. RESULTS: ESI version 4 had a sensitivity of 95.5%, specificity of 80.3%, with AUC of 0.879 (95%CI 0.834-0.925) in identifying high urgency patients at levels 1 and 2. Modified PEWS had comparatively lower sensitivity of 79.1%, specificity of 97.8%, with AUC of 0.885 (95%CI 0.825-0.994) in identifying high urgency patients at score of ≥3. The ESI version 4 was found to be a better predictor of admission than the modified PEWS, with a sensitivity of 98.2%. Both the scores were able to identify patients at risk of mortality with a sensitivity of 100%. CONCLUSION: ESI version 4 is a better triage tool than modified PEWS in pediatric population in a tertiary care public hospital setting in this region.

Utility of Cerebrospinal Fluid and Serum Procalcitonin for the Diagnosis of Neonatal Meningitis.

OBJECTIVE: Positive CSF culture is the gold standard for the diagnosis of meningitis but it carries poor sensitivity. CSF procalcitonin (PCT) is shown to have some utility for the diagnosis of meningitis though there are limited studies in neonatal age group. We planned this study to compare CSF, serum, and CSF to serum PCT levels in neonates with confirmed, probable, and nonmeningitis groups to determine its optimal cut-off in CSF and serum for diagnosing meningitis. STUDY DESIGN: Sixty-seven neonates who qualified for lumbar puncture were enrolled in the study. Neonates were categorized into confirmed meningitis, i.e., CSF cytochemistry and culture positive (N = 17), probable meningitis, i.e., CSF cytochemistry positive but culture negative (N = 25) and nonmeningitis, i.e., both cytochemistry and culture negative (N = 25). CSF and serum samples were stored at -80°C for PCT assay. RESULTS: Significant difference was seen in mean of CSF PCT in neonates with confirmed (0.31 ng/mL), probable (0.22 ng/mL), and nonmeningitis (0.11 ng/mL) groups. Similarly, significant difference was observed in serum PCT levels also, though the ratio of serum to CSF PCT was comparable. At cut-off of 0.2 ng/mL, CSF PCT had sensitivity of 95.2% and specificity of 96% in the diagnosis of meningitis. CONCLUSION: CSF PCT is more specific marker for the diagnosis of neonatal meningitis as compared with serum PCT and CSF to serum PCT ratio. KEY POINTS: · CSF procalcitonin is a better marker than serum procalcitonin for diagnosing neonatal meningitis.. · It is better than serum procalcitonin and CSF to serum procalcitonin ratio.. · At cut-off of >0.2 ng/mL CSF procalcitonin can diagnose neonatal meningitis with 96% specificity..

PaO2/FiO2 Ratio as Predictor of Mortality in Neonates with Meconium Aspiration Syndrome.

OBJECTIVES: Partial arterial pressure of oxygen/fraction of oxygen in inspired air (PaO2/FiO2) ratio has been used as a predictor of outcome in some neonatal conditions, but has not been used in meconium aspiration syndrome (MAS). This study was conducted with the objective to study if the PaO2/FiO2 ratio of < 200 at 6, 12, and 24 hours of life can predict mortality in neonates with MAS. STUDY DESIGN: Two hundred neonates with MAS were included in the study. PaO2/FiO2 ratio was calculated at 6, 12, and 24 hours of life. Sensitivity, specificity, predictive values, and likelihood ratio at cut-off < 200 to predict mortality was calculated. RESULTS: PaO2/FiO2 ratio at cut-off of < 200 was found to predict mortality in neonates with MAS with 94.1% sensitivity and 96.6% specificity. It was also able to predict development of severe MAS. CONCLUSION: PaO2/FiO2 at < 200 can predict all-cause mortality in neonates with MAS. It can be used as vital tool in identifying newborns at high risk, thus helping in focused care.

Effect of Carbamazepine and Valproate Monotherapy on Cardiovascular Risks in Epileptic Children.

OBJECTIVE: We determined the effects of carbamazepine and valproic acid on the serum lipids and apolipoprotein A and B in epileptic children on long-term monotherapy and 3 months after drug discontinuation. METHOD: Thirty-three epileptic children (17 boys, 16 girls, mean age 9.79 ± 2.5 years) were evaluated for serum lipids and lipoprotein results at the initiation of antiepileptic drug tapering and 3 months after cessation of antiepileptic therapy. RESULTS: In the carbamazepine group (n = 13), there was no significant difference in the lipid profile at the end of therapy or at 3 months after the discontinuation, whereas in the valproate group (n = 20), triglycerides and apoprotein B and high-density lipoprotein cholesterol increased significantly 3 months after discontinuation. The ratios of total cholesterol:high-density lipoprotein improved but low-density lipoprotein:high-density lipoprotein and apolipoprotein:apolipoprotein remained unchanged. CONCLUSION: Because these ratios are better predictor of atherosclerosis risk than the absolute values, the overall risk is not increased by the long-term use of carbamazepine and valproate.

CLOVE syndrome with nevus unis lateris: report of a case.

Congenital lipomatous overgrowth, vascular malformations, and epidermal nevi (CLOVE) syndrome is a recently described syndrome similar to Proteus syndrome but lacking the progressive or distorting bony overgrowth of Proteus syndrome. We describe a neonate with features of CLOVE syndrome and nevus unius lateris.

Management of chemotherapy-induced nausea and vomiting.

CONTEXT: Chemotherapy-induced nausea and vomiting (CINV) is a significant problem in the treatment of children with cancer. The last decade has seen a variety of newer antiemetics being evaluated for CINV; their efficacy and side effects need to be assessed in children. This article attempts to highlight this revised management of CINV. EVIDENCE ACQUISITION: Online search; journals. Search period: 6 months. RESULTS: Newer drugs (aprepitant, fosapritant and newer 5HT3 antagonists) have been found to be effective in CINV: both acute and delayed phases. Most of the available literature is, however, based on adult oncology patients, with a few trials on adolescent patients. CONCLUSION: Every child receiving treatment for cancer should be evaluated for possible CINV. Their treatment should take into account the emetogenic potential of the chemotherapeutic drugs. Newer antiemetic drugs have good efficacy and can be tried in pediatric patients, especially in children > 11 years of age.
