The Indian Academy of Pediatrics and Directorate General of Health Services, Government of India White Paper on Transition of Care for Youth with Special Health Care Needs

Over the years, survival of children with chronic diseases has significantly improved and a large proportion of them now are entering into adulthood. Transition of Care (ToC) of such patients with having childhood onset of chronic diseases to the adult health care system is well organized in developed countries, although it is an emerging concept in India. In situations where the systems for ToC are not in place, such cases are fraught with unsatisfactory health outcomes. With proper ToC in place, these patients are likely to receive uninterrupted care by the adult care physicians and hence reach their full potential. This document highlights the need, rationale and way forward for ToC of youth with special health care needs (YSHCN) across the country. It also describes the standard operating procedures to develop the ToC at a hospital level for clinicians and administrators.

Development and Validation of MRI Imaging Biomarkers for Prostate Cancer Using Deep Learning

PURPOSE/OBJECTIVE(S)

Given the increasing number of treatment options for patients with localized prostate cancer (PCa), there is a need for biomarkers to aid in risk stratification. Specifically, novel biomarkers can aid in the identification of high-risk phenotypes among similar patients in traditional NCCN risk groupings. One promising area for development is using pre-treatment prostate MRI to identify imaging biomarkers to identify prostate cancer patients at highest risk for recurrence. We hypothesized that deep learning could be leveraged to identify imaging biomarkers of aggressive PCa from pre-treatment prostate MRIs.

MATERIALS/METHODS

Our study included 1,020 patients treated at our institution between 2010-2022. Given pathologic extraprostatic extension (EPE) and seminal vesicle invasion (SVI) are associated with higher risk of treatment failure, we hypothesized that deep learning models which identified radiographic EPE and SVI would provide non-invasive imaging biomarkers associated with PCa prognosis. We trained two separate deep learning models using convolutional neural networks to predict SVI and EPE respectively. The model inputs were T2W prostate MRIs (n = 894) and models consisted of 8 convolutional layers. Dropout, L2 regularization, and data augmentation were used to improve model generalizability and reduce overfitting. Discriminatory ability of each model was measured using AUC on a blinded external test set of 221 patients. To assess the clinical utility of our imaging biomarkers, log-rank tests were used to evaluate biochemical free survival (BFS) for patients classified as high risk to patients classified as low risk. Biochemical failure was defined as post-treatment PSA >0.1 for patients who underwent radical prostatectomy (RP) or PSA >2ng/ml above nadir for patients receiving radiation therapy.

RESULTS

Within our cohort of 1,020 patients the median age was 66 with a median follow up of 4 years. 49.3% (n = 503) underwent RP and 50.7% (n = 517) received EBRT. 4% (n = 41) were low risk, 62.4% (n = 636) were intermediate risk, and 33% (n = 337) were high risk based on NCCN criteria. Deep learning models showed good discriminatory ability for both EPE (AUC 0.66) and SVI (AUC 0.74). Both imaging biomarkers showed prognostic ability to identify high risk prostate phenotypes. Patients deemed high risk based on EPE classifier had worse BFS (median 5 vs 9 years, p<.001). Similarly, patients classified as high risk based on SVI also showed worse BFS (median 5 vs 9 years, p = 0.024). Among intermediate risk patients, EPE biomarker showed an ability to identify high risk phenotypes (median 6 vs 9 years, p = 0.024).

CONCLUSION

Deep learning classifiers of prostate MRIs demonstrated the ability to stratify high-risk prostate cancer phenotypes beyond traditional risk paradigms. Imaging biomarkers represent a non-invasive method to help aid in the personalization of treatment for patients with localized prostate cancer and identify patients who potentially require treatment escalation.

Selected-Lesion Stereotactic Radiosurgery in Treatment of Patients with Multiple Brain Metastases: A Single Institution Retrospective Study

PURPOSE/OBJECTIVE(S)

Stereotactic Radiosurgery (SRS) has been increasingly used as first and subsequent-line treatments for brain metastases. While the appropriate cut-off number of lesions for SRS is still being debated nationally in patients with multiple brain metastases, some institutions use an alternate approach particularly for patients with >10-15 lesions. Selected-lesion SRS (SL-SRS) is where only a subset of lesions are chosen for initial SRS treatment leaving small and clinically inconsequential lesions for treatment using alternate or delayed treatments. This study aims to investigate the patient selection criteria, patient and tumor characteristics and analyze the outcomes in patients receiving SL-SRS for brain metastases at our institution.

MATERIALS/METHODS

Clinical data from patients treated using the SL-SRS approach from 2012-2022 at our institution were retrospectively reviewed. Patients were divided into cohorts based on overall survival from time of SL-SRS treatment and indications for using SL-SRS. We compared the patient characteristics (age, histology, KPS, dsGPA), tumor characteristics (cumulative tumor volumes, tumor dose, number of brain metastases found, number of metastases treated), treatment characteristics (chemotherapy, immunotherapy, previous SRS/ radiation, previous WBRT) and the reason for decision to recommend SL-SRS across these cohort.

RESULTS

A total of 102 patients were treated using the SL-SRS approach. Indications for using SL-SRS were immunotherapy trial (n = 40), CNS penetrating drug options available (n = 18), patient refusing WBRT (n = 6), palliative after prior WBRT/SRS (n = 28), WBRT planned to follow SRS (n = 9). 31 patients were alive at 12 months and 21 patients at 24 months. In patients surviving <12 months - the most common indications for SL-SRS were CNS palliation in the setting of progressive disease after prior WBRT or SRS. Patients in this group had median KPS< = 60 and had predominantly non-small cell carcinoma primary diagnosis. In those patients surviving >12 months - the most common indication for SL-SRS was participation in CNS-penetrant agent clinical trials without WBRT. Patients in this group were more likely to be female, had a median KPS of 90, had predominantly diagnoses of melanoma. Following the SL-SRS treatment, 14 patients required further SRS and 4 patients went on to WBRT in the >12-month survival group. No patients died of CNS progression alone. 10 patients survived 24 months without requiring further CNS radiation.

CONCLUSION

In our institution, SL-SRS has predominantly been used either as palliative treatment at time of disease progression or to facilitate entry onto clinical trial with immunotherapy or potentially CNS-penetrant agents. The latter indication resulted in 47.6% patients surviving >24 month without the need for additional radiation to the CNS and therefore SL-SRS should be considered a feasible, safe and effective alternative to either WBRT or SRS treatment of all radiographically visible brain metastases.

Association of Screen Time Usage and Physical Activity With Overweight and Obesity Among School-Going Children in Uttar Pradesh

Background Being overweight during childhood refers to excess weight for a given height, while obesity denotes excess body fat. These conditions stem from surplus calorie intake and insufficient physical activity. Escalating pediatric obesity is linked to modern sedentary lifestyles, marked by increased screen time, reduced exercise, and poor diets. Once believed to be a concern in affluent nations, obesity now affects developing countries like India due to changing eating habits and urbanization. Despite limitations in measurement tools, such as body mass index (BMI) and waist circumference, recognizing sedentary behaviors such as prolonged screen time is pivotal. The rapidly rising prevalence of pediatric obesity has become a major public health concern; therefore, we conducted this study to determine the prevalence and association of screen time usage with being overweight in school-going children (aged 8-15 years). Methodology This observational, cross-sectional study was conducted in Greater Noida, Uttar Pradesh over 18 months (January 2019 to June 2020) after obtaining institutional ethical committee approval. Participants were 8 to 15-year-old students from three co-educational secondary schools in the region. Children with motor or developmental disabilities were excluded. Written informed parental consent and school permission were secured. Anthropometric measurements included weight (SECA 874 U scale) and height (SECA213 stadiometer), which were used to calculate BMI. Overweight/obesity status followed the Indian Academy of Pediatrics guidelines. A validated questionnaire assessed screen time, and a validated Physical Activity Questionnaire measured physical activity. Both questionnaires were administered twice to validate data. SPSS version 23.0 (IBM Corp., Armonk, NY, USA) was used for data analyses (descriptive, t-test, analysis of variance (ANOVA) test, and chi-square test). P-values <0.05 were considered significant. Results This study involved 604 participants. Among them, 47.7% had a normal BMI, 37.4% were overweight, and 14.9% were obese. Most participants (97.4%) reported screen time of over 60 minutes daily, while 2.6% reported lower screen time. ANOVA revealed significant differences in daily (F = 16.014, p < 0.001) and weekly (F = 16.175, p < 0.001) screen time among BMI categories. Low physical activity was prevalent (97.7%). ANOVA showed significant variations in physical activity scores and durations (p < 0.001), with normal-weight individuals exhibiting higher levels. Conclusions The rising prevalence of overweight among children underscores the need for early intervention strategies, emphasizing the importance of reducing screen time and promoting increased physical activity. These measures are critical in addressing the growing challenge of being overweight during childhood and its potential long-term health implications.

3D Capsule Networks for Brain Image Segmentation

BACKGROUND AND PURPOSE

Current autosegmentation models such as UNets and nnUNets have limitations, including the inability to segment images that are not represented during training and lack of computational efficiency. 3D capsule networks have the potential to address these limitations.

MATERIALS AND METHODS

We used 3430 brain MRIs, acquired in a multi-institutional study, to train and validate our models. We compared our capsule network with standard alternatives, UNets and nnUNets, on the basis of segmentation efficacy (Dice scores), segmentation performance when the image is not well-represented in the training data, performance when the training data are limited, and computational efficiency including required memory and computational speed.

RESULTS

The capsule network segmented the third ventricle, thalamus, and hippocampus with Dice scores of 95%, 94%, and 92%, respectively, which were within 1% of the Dice scores of UNets and nnUNets. The capsule network significantly outperformed UNets in segmenting images that were not well-represented in the training data, with Dice scores 30% higher. The computational memory required for the capsule network is less than one-tenth of the memory required for UNets or nnUNets. The capsule network is also >25% faster to train compared with UNet and nnUNet.

CONCLUSIONS

We developed and validated a capsule network that is effective in segmenting brain images, can segment images that are not well-represented in the training data, and is computationally efficient compared with alternatives.

In-hospital mortality risk stratification in children aged under 5 years with pneumonia with or without pulse oximetry: A secondary analysis of the Pneumonia REsearch Partnership to Assess WHO REcommendations (PREPARE) dataset

OBJECTIVES

We determined the pulse oximetry benefit in pediatric pneumonia mortality risk stratification and chest-indrawing pneumonia in-hospital mortality risk factors.

METHODS

We report the characteristics and in-hospital pneumonia-related mortality of children aged 2-59 months who were included in the Pneumonia Research Partnership to Assess WHO Recommendations dataset. We developed multivariable logistic regression models of chest-indrawing pneumonia to identify mortality risk factors.

RESULTS

Among 285,839 children, 164,244 (57.5%) from hospital-based studies were included. Pneumonia case fatality risk (CFR) without pulse oximetry measurement was higher than with measurement (5.8%, 95% confidence interval [CI] 5.6-5.9% vs 2.1%, 95% CI 1.9-2.4%). One in five children with chest-indrawing pneumonia was hypoxemic (19.7%, 95% CI 19.0-20.4%), and the hypoxemic CFR was 10.3% (95% CI 9.1-11.5%). Other mortality risk factors were younger age (either 2-5 months [adjusted odds ratio (aOR) 9.94, 95% CI 6.67-14.84] or 6-11 months [aOR 2.67, 95% CI 1.71-4.16]), moderate malnutrition (aOR 2.41, 95% CI 1.87-3.09), and female sex (aOR 1.82, 95% CI 1.43-2.32).

CONCLUSION

Children with a pulse oximetry measurement had a lower CFR. Many children hospitalized with chest-indrawing pneumonia were hypoxemic and one in 10 died. Young age and moderate malnutrition were risk factors for in-hospital chest-indrawing pneumonia-related mortality. Pulse oximetry should be integrated in pneumonia hospital care for children under 5 years.

Insulin Resistance in children on Sodium Valproate - A hospital based cross-sectional study in Indian children

Our objective was to compare the point prevalence of insulin resistance (IR) in children taking sodium valproate (VPA) and phenytoin sodium (PS) monotherapy for >1 year. 150 children, aged 6-18 years, were categorized (50 each) into - group A (VPA), group B (PS) and group C (healthy controls age-sex matched with group A). Groups were compared for metabolic complications and risk factors assessed. The point prevalence of IR and non-alcoholic fatty liver disease was significantly higher in children on VPA (12% and 34% respectively) than on PS and healthy controls, regardless of age, sex, pubertal and nutritional status. The presence of central obesity, acanthosis, hypertension, dyslipidaemia was significantly associated with IR but none showed an independent association on multivariate analysis. Therapy with VPA makes children susceptible to metabolic complications. Close monitoring will facilitate early detection and timely intervention.

Assembling a global database of child pneumonia studies to inform WHO pneumonia management algorithm: Methodology and applications

Background

The existing World Health Organization (WHO) pneumonia case management guidelines rely on clinical symptoms and signs for identifying, classifying, and treating pneumonia in children up to 5 years old. We aimed to collate an individual patient-level data set from large, high-quality pre-existing studies on pneumonia in children to identify a set of signs and symptoms with greater validity in the diagnosis, prognosis, and possible treatment of childhood pneumonia for the improvement of current pneumonia case management guidelines.

Methods

Using data from a published systematic review and expert knowledge, we identified studies meeting our eligibility criteria and invited investigators to share individual-level patient data. We collected data on demographic information, general medical history, and current illness episode, including history, clinical presentation, chest radiograph findings when available, treatment, and outcome. Data were gathered separately from hospital-based and community-based cases. We performed a narrative synthesis to describe the final data set.

Results

Forty-one separate data sets were included in the Pneumonia Research Partnership to Assess WHO Recommendations (PREPARE) database, 26 of which were hospital-based and 15 were community-based. The PREPARE database includes 285 839 children with pneumonia (244 323 in the hospital and 41 516 in the community), with detailed descriptions of clinical presentation, clinical progression, and outcome. Of 9185 pneumonia-related deaths, 6836 (74%) occurred in children <1 year of age and 1317 (14%) in children aged 1-2 years. Of the 285 839 episodes, 280 998 occurred in children 0-59 months old, of which 129 584 (46%) were 2-11 months of age and 152 730 (54%) were males.

Conclusions

This data set could identify an improved specific, sensitive set of criteria for diagnosing clinical pneumonia and help identify sick children in need of referral to a higher level of care or a change of therapy. Field studies could be designed based on insights from PREPARE analyses to validate a potential revised pneumonia algorithm. The PREPARE methodology can also act as a model for disease database assembly.

Thrombosis and thromboembolism: Brighton collaboration case definition and guidelines for data collection, analysis, and presentation of immunization safety data

This is a Brighton Collaboration case definition of thrombosis and thromboembolism to be used in the evaluation of adverse events following immunization, and for epidemiologic studies for the assessment of background incidence or hypothesis testing. The case definition was developed by a group of experts convened by the Coalition for Epidemic Preparedness Innovations (CEPI) in the context of active development of SARS-CoV-2 vaccines. The case definition format of the Brighton Collaboration was followed to develop a consensus definition and defined levels of certainty, after an exhaustive review of the literature and expert consultation. The document underwent peer review by the Brighton Collaboration Network and by selected expert reviewers prior to submission.

Diagnostic Accuracy of Parents' Evaluation of Developmental Status (PEDS), PEDS Developmental Milestones, and PEDS Combined in Indian Children Aged Less than 2 Years

OBJECTIVE

To assess the diagnostic accuracy of Parent's Evaluation of Developmental Status (PEDS), PEDS Developmental Milestones (PEDS:DM) and PEDS Combined for developmental screening of Indian children aged less than 2 y.

METHOD

A hospital-based study of diagnostic accuracy was conducted over 17 mo. Children under 24 mo (n = 180) were enrolled after exclusion of severe illnesses or known neurodevelopment disorders. The index tools included standardized Hindi translations of PEDS and PEDS:DM. The reference tool was Developmental Assessment Scale for Indian Infants (DASII). Both were administered by blinded researchers. Parameters of diagnostic accuracy were computed.

RESULTS

There were 13 (7.2%) failures in PEDS, 119 (66.1%) in PEDS:DM and 119 (66.1%) in PEDS Combined. DASII identified 3 children with developmental delay. Sensitivity (Sn) [95% CI] of PEDS was 33.3 [0.8-90.6] and Specificity (Sp) 93.2 [88.5-96.5]. The Sn and Sp of both PEDS:DM and PEDS Combined were 100 [29.2-100] and 34.5 [27.5-42.0], respectively.

CONCLUSIONS

Hindi translations of PEDS, PEDS:DM and PEDS Combined are not suitable for developmental screening of children less than 2 y due to suboptimal diagnostic accuracy.

Derivation and validation of a novel risk assessment tool to identify children aged 2–59 months at risk of hospitalised pneumonia-related mortality in 20 countries

Introduction

Existing risk assessment tools to identify children at risk of hospitalised pneumonia-related mortality have shown suboptimal discriminatory value during external validation. Our objective was to derive and validate a novel risk assessment tool to identify children aged 2–59 months at risk of hospitalised pneumonia-related mortality across various settings.

Methods

We used primary, baseline, patient-level data from 11 studies, including children evaluated for pneumonia in 20 low-income and middle-income countries. Patients with complete data were included in a logistic regression model to assess the association of candidate variables with the outcome hospitalised pneumonia-related mortality. Adjusted log coefficients were calculated for each candidate variable and assigned weighted points to derive the Pneumonia Research Partnership to Assess WHO Recommendations (PREPARE) risk assessment tool. We used bootstrapped selection with 200 repetitions to internally validate the PREPARE risk assessment tool.

Results

A total of 27 388 children were included in the analysis (mean age 14.0 months, pneumonia-related case fatality ratio 3.1%). The PREPARE risk assessment tool included patient age, sex, weight-for-age z-score, body temperature, respiratory rate, unconsciousness or decreased level of consciousness, convulsions, cyanosis and hypoxaemia at baseline. The PREPARE risk assessment tool had good discriminatory value when internally validated (area under the curve 0.83, 95% CI 0.81 to 0.84).

Conclusions

The PREPARE risk assessment tool had good discriminatory ability for identifying children at risk of hospitalised pneumonia-related mortality in a large, geographically diverse dataset. After external validation, this tool may be implemented in various settings to identify children at risk of hospitalised pneumonia-related mortality.

Point Prevalence of Peripheral Neuropathy in Children and Adolescents with Type 1 Diabetes Mellitus

OBJECTIVE

To assess the point prevalence of peripheral neuropathy (PN) in children with type 1 diabetes mellitus (T1DM) and to determine their predictors.

METHODS

In this cross-sectional study, children aged 8-18 y with T1DM on insulin therapy for > 2 y and free from acute complications were enrolled. All participants were evaluated for symptoms of PN with diabetic neuropathy symptom (DNS) score and underwent a detailed neurological examination. Assessment of nerve dysfunction was done using nerve conduction studies (NCS). The disease-related factors that increase the risk of PN were determined.

RESULTS

Fifty children (52% boys) were enrolled with mean age of 12.2 ± 2.8 y and duration of diabetes 5.1 ± 2.1 y. No subject had clinical evidence or DNS score suggestive of PN. Twenty-eight (56%) children demonstrated subclinical neuropathy on NCS. Proportion of children with pure motor, pure sensory, and mixed motor-sensory neuropathy was 40%, 2%, and 14%, respectively. The peroneal nerve was the most common motor nerve affected. Poor glycemic control (HbA1c > 9%) and longer duration of diabetes (> 5 y) were significantly associated with the risk of PN (p value < 0.05).

CONCLUSION

A large proportion of children with T1DM have subclinical PN. Poor glycemic control and longer duration of diabetes are risk factors for nerve dysfunction. Neurophysiological studies should be performed in these children to facilitate early detection.

Early Childhood Development: A Paradigm Shift From Developmental Screening and Surveillance to Parent Intervention Programs

A large proportion of children under the age of five years who do not attain their expected developmental potential belong to low- and middle-income countries (LMICs). The strategies used for identifying children with high risk for developmental delay/disorders include developmental screening, surveillance, and monitoring. Suitability criteria for developmental screening tools in LMICs have been established, but few tools meet all the benchmarks. Based on these, the authors identified two tools that may be considered suitable in the Indian context; the International guide for monitoring child development and the Monitoring child development in the integrated management of childhood illnesses context. However, implementing and sustaining a universal developmental screening program using these is not feasible in the present circumstances. There is emerging evidence that parent intervention programs have significant impact on outcomes related to early childhood development (ECD). The nurturing care framework encompasses five strategies known to enhance ECD in young children even in the presence of adversities; good health, adequate nutrition, responsive caregiving, opportunities for early learning and safety and security. This article discusses the paradigm shift to incorporation of nurturing care-based preventive, supportive and promotive health care services in office practice with active parental involvement. This may prove to be a better option with a more positive, long lasting and quicker impact on ECD.

The Status of Early Childhood Development in India: Will We Reach the Countdown to 2030 Targets?

Early childhood development (ECD) provides building blocks for future educational achievement, emotional and moral development; the early years of life provide a critical window of opportunity for intervention. Experts across the world are emphasizing on promotion of ECD through the 5-pronged Nurturing Care Framework (NCF). The Sustainable Development Goals have focussed on optimum development for all children by 2030. For India, with 164.5 million population of children between 0-6 years, the magnitude of the problem is huge. We have been focusing on ECD since the launching of the Integrated Child Development Scheme (ICDS) in 1976. Many national policies and programs have evolved since then to promote ECD. Inspite of all efforts, the overall picture of early childhood development in India is still not optimal, due to multiple factors. All five components of nurturing care framework have not been included comprehensively in the services offered. If India focuses on these areas and comes up with a convergent ECD delivery system through a single portal that can be provided with equity at the grassroot level, coupled with proper documentation, we may proceed towards our goals at a better pace. Multiple stakeholders (the government, public and private health care providers, non-government organizations, professional bodies) need to work in synergy to enable us to reach the 2030 goals.

External validation of the RISC, RISC-Malawi, and PERCH clinical prediction rules to identify risk of death in children hospitalized with pneumonia

BACKGROUND

Existing scores to identify children at risk of hospitalized pneumonia-related mortality lack broad external validation. Our objective was to externally validate three such risk scores.

METHODS

We applied the Respiratory Index of Severity in Children (RISC) for HIV-negative children, the RISC-Malawi, and the Pneumonia Etiology Research for Child Health (PERCH) scores to hospitalized children in the Pneumonia REsearch Partnerships to Assess WHO REcommendations (PREPARE) data set. The PREPARE data set includes pooled data from 41 studies on pediatric pneumonia from across the world. We calculated test characteristics and the area under the curve (AUC) for each of these clinical prediction rules.

RESULTS

The RISC score for HIV-negative children was applied to 3574 children 0-24 months and demonstrated poor discriminatory ability (AUC = 0.66, 95% confidence interval (CI) = 0.58-0.73) in the identification of children at risk of hospitalized pneumonia-related mortality. The RISC-Malawi score had fair discriminatory value (AUC = 0.75, 95% CI = 0.74-0.77) among 17 864 children 2-59 months. The PERCH score was applied to 732 children 1-59 months and also demonstrated poor discriminatory value (AUC = 0.55, 95% CI = 0.37-0.73).

CONCLUSIONS

In a large external application of the RISC, RISC-Malawi, and PERCH scores, a substantial number of children were misclassified for their risk of hospitalized pneumonia-related mortality. Although pneumonia risk scores have performed well among the cohorts in which they were derived, their performance diminished when externally applied. A generalizable risk assessment tool with higher sensitivity and specificity to identify children at risk of hospitalized pneumonia-related mortality may be needed. Such a generalizable risk assessment tool would need context-specific validation prior to implementation in that setting.

Growth faltering in early infancy: highlights from a two-day scientific consultation

The consultation was supported by the Biotechnology Industry Research Assistance Council (BIRAC), the Indian Academy of Pediatrics (Nutrition Chapter), Vardhman Mahavir Medical College and Safdarjung Hospital, and the Society for Applied Studies. It brought together researchers, clinicians, policy makers and program managers.

Use of the International League Against Epilepsy (ILAE) 1989, 2010, and 2017 Classification of Epilepsy in children in a low-resource setting: A hospital-based cross-sectional study

OBJECTIVES

This cross-sectional study was designed to test the applicability of the 1989, 2010, and 2017 International League Against Epilepsy (ILAE) classification of epilepsy in children from a resource-limited setting in India.

METHODS

Classification of seizure types and syndromes was done through parental interviews and review of medical records in children with epilepsy aged one month to 18 years. Available investigations including EEG, MRI, and metabolic/genetic tests were used in classifying patients as per the 1989, 2010, and 2017 ILAE (level II-epilepsy type) classification. We compared the proportion of children remaining unclassified by each scheme.

RESULTS

Seven hundred and twenty-six children (436 males, mean age 6.4 ± 4.6 years) were enrolled. Using the 1989 ILAE classification, we were able to classify 95.7%, and 82.6% children by the 2010 scheme. The 2017 ILAE classification could classify all 726 children at level I (seizure type), 664 (91.0%) children at level II (epilepsy type), and an electroclinical syndrome could be identified in 409 (56.1%) of the children. An etiology could be identified in 75%, perinatal brain injury being the most frequent. West syndrome was the most common electroclinical syndrome, identified in 22.7% patients. The 1989 ILAE classification system was superior to the 2010 system (P = .01) in epilepsy classification. There was no difference between the 1989 and 2017 schemes (P = .31) or the 2010 and 2017 schemes (P = .10).

SIGNIFICANCE

The 2017 ILAE classification, being multidimensional, allowed classification of children who could not undergo extensive evaluation due to economic constraints and also provided room for overlapping etiologies.

Sensorineural hearing loss (SNHL) as an adverse event following immunization (AEFI): Case definition & guidelines for data collection, analysis, and presentation of immunization safety data

This is a Brighton Collaboration case definition of the term "Sensorineural Hearing Loss" to be utilized in the evaluation of adverse events following immunization. The case definition was developed by a group of experts convened by the Coalition for Epidemic Preparedness Innovations (CEPI) in the context of active development of vaccines for Lassa Fever and other emerging pathogens. The case definition format of the Brighton Collaboration was followed to develop a consensus definition and define levels of diagnostic certainty, after an exhaustive review of the literature and expert consultation. The document underwent peer review by the Brighton Collaboration Network.

Clinical Profile and Short-term Outcome of Pediatric Status Epilepticus at a Tertiary-care Center in Northern India

OBJECTIVE

To assess clinical profile and short term treatment outcomes of pediatric status epilepticus (SE) at a tertiary-care center in northern India.

METHODS

Prospective cohort study enrolled children aged 1 month to 18 years presenting with SE to the emergency department. Enrolled children (109) were treated as per hospital protocols. Clinical features during hospitalization were noted. Pediatric overall performance category (POPC) scale was used for classification of outcome at the time of discharge.

RESULTS

Acute symptomatic etiology was identified in 66 (60.6%) cases (CNS infections were predominant). Previous diagnosis of epilepsy was found in 32 (29.4%) children; and benzodiazepine responsive SE were seen in 65 (59.6%) children. Predictors of unfavorable outcome were acute symptomatic etiology (adjusted OR 4.50; 95% CI 1.49, 13.62) and no treatment administered prior to hospital (adjusted OR 3.97; 95% CI 1.06, 14.81).

CONCLUSIONS

Acute symptomatic etiology, mainly acute CNS infections, is the leading cause of SE in this region. Early and pre-hospital management with benzodiazepines may improve SE outcome.

Neuro-Developmental and Epilepsy Outcomes of Children with West Syndrome: A Cross-Sectional Study from North India

Objectives:

To assess the neurodevelopmental outcome of West syndrome (WS) in Indian children, who differ in their clinical profile from the western population.

Materials and Methods:

This cross-sectional study enrolled children aged 2--5 years with prior diagnosis of WS between November 2013 and March 2015. They were assessed for epilepsy outcome and developmental outcome using developmental profile 3 (DP3) and vineland adaptive behavioral scale II (VABS II).

Results:

Sixty-one children were enrolled. Perinatal asphyxia (40.9%), neonatal hypoglycemia (14.8%), and neonatal meningitis (9.8%) were predominant causes among the children with known etiology. Favorable epilepsy outcome (seizure freedom for >6 months) was observed in 29/61 patients (47.5%). Moderate to severe developmental delay was observed in 55/61 children (91.8%). Favorable developmental outcome (GDS by DP3 >70) was observed in just 5/61 (8%) patients.

Conclusions:

This study highlights the high prevalence of developmental delay in this population of children with WS, with adverse perinatal events being the most common etiology.

Guillain-Barre syndrome in North Indian children: Clinical and serial electrophysiological features

Background

Guillain-Barre syndrome (GBS) is a common acquired polyneuropathy in children.

Aim

To describe the clinical and serial electrophysiological features along with short-term outcomes of children with GBS in north India.

Setting and Design

This was a prospective study conducted at a tertiary care pediatric hospital in north India.

Materials and Methods

Consecutive children, aged 2 to 18 years, with GBS, presenting within 4-weeks of onset of weakness, diagnosed on clinical and/or electrophysiological grounds, were enrolled. The enrolled children underwent a detailed clinical-assessment followed by nerve conduction studies. Repeat nerve conduction studies were performed after 2-weeks of the first study to determine changes in the electrophysiological subtype. The patients were followed up for 3 months.

Results

Thirty-six children were studied. The mean age at presentation was 5.1 years [standard deviation (SD): 2.1]. The mean medical research council (MRC)-sum-score at admission was 24.1 (SD: 10.4). Thirty-three children (91%) had loss of ambulation, 24 (66%) had cranial nerve involvement, and 6 (16.6%) required ventilation. At presentation, 20 had acute motor axonal neuropathy (AMAN), 13 had acute inflammatory demyelinating polyneuropathy (AIDP), 2 had in-excitable nerves, and 1 had normal findings. Four children, initially diagnosed as AIDP, had AMAN with reversible conduction failure on the repeat study. The final classification was AMAN in 25 (69.4%; 95% confidence interval (CI), 51.9-83.7%) and AIDP in 9 children (25%; 95% CI, 12.1-42.2%). Only one patient was nonambulatory at a 3-month follow-up (n = 32). The Erasmus GBS outcome score was 2 in 2 (5.6%), 3 in 5 (13.9%), 4 in 26 (72.2%), and 5 in 3 (8.3%) patients.

Conclusions

The serial electrophysiological studies were helpful in establishing the final correct diagnosis.

Diagnostic Accuracy of Indian Scale for Assessment of Autism in Indian Children Aged 2-5 Years

OBJECTIVE

To determine the diagnostic accuracy of Indian Scale for Assessment of Autism (ISAA) in children aged between 2-5 years. Design: Setting:.

STUDY DESIGN

Study of diagnostic accuracy.

PARTICIPANTS

A consecutive sample of 500 children with suspected Autism (delay or regression of developmental milestones, delay or regression in speech, age-inappropriate understanding, behaviour, play and/or social interaction) was recruited.

SETTING

Tertiary level hospital, (November 2015 - November 2017).

PROCEDURE

Each child underwent an expert comprehensive assessment of Autism (reference tool) that included history, observation, examination, diagnostic criteria for Autism Spectrum Disorder (ASD) of the Diagnostic and Statistical Manual of Mental Disorders', 5th edition, Childhood Autism Rating Scale-2 (CARS2), developmental status and adaptive function. This was followed by the administration of ISAA (test tool) in Hindi language. Parameters of diagnostic accuracy and Receiver Operating Characteristic curves were computed.

MAIN OUTCOME MEASURES

ASD based on (i) expert assessment, (ii) CARS-2, and (iii) ISAA.

RESULTS

In children aged 2-3 years, sensitivity of ISAA was 100% (95% CI 98.2% -100%), specificity 28.9% (95% CI 17.7% to 43.4%), positive likelihood ratio 1.4 and negative likelihood ratio 0. In 3-5 year olds, sensitivity was 99.6% (95% CI 97.6% to 99.6%), specificity 33.3% (95% CI 15.1% to 58.3%), positive likelihood ration 1.5 and negative likelihood ratio 0.01. The degrees of autism based on the existing cut off values were inaccurate.

CONCLUSIONS

ISAA has sub-optimal performance in diagnosing and assessing severity in 2-5 year old children.

Addition of pyridoxine to prednisolone in the treatment of infantile spasms: A pilot, randomized controlled trial

Background

West syndrome is a catastrophic epilepsy syndrome characterized by infantile spasms, hypsarrhythmia, and developmental arrest or regression.

Aim

The aim of this study was to explore the role of pyridoxine in the management of infantile spasms.

Setting and Design

This was a pilot, randomized, open-label trial conducted at a tertiary level hospital from November 2012 to March 2014.

Materials and Methods

Children aged 3 months to 3 years presenting with infantile spasms in clusters (at least 1 cluster/day) with hypsarrhythmia or its variants on electroencephalogram (EEG) were enrolled. The study participants were randomized to receive either oral prednisolone (4 mg/kg/day) alone or 30 mg/kg/day of pyridoxine with oral prednisolone. The primary outcome measure was the proportion of children who achieved spasm freedom for 48 h on day-14 after treatment initiation, as per parental reports, in both the groups. The adverse effects were also monitored. The study was registered with clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT01828437).

Results

Sixty-two children were randomized into the two groups with comparable baseline characteristics. The proportion of children with spasm cessation on day-14 was similar in the two groups (39 vs. 37%, P = 0.98). The adverse effects were comparable in both the groups.

Conclusions

The combination of pyridoxine with oral prednisolone was not found to be a beneficial therapy as compared to prednisolone alone in the treatment of infantile spasms in this pilot study. However, high dose pyridoxine may be safe in children with infantile spasms.

Incidence of vincristine induced neurotoxicity in children with acute lymphoblastic leukemia and its correlation with nutritional deficiencies

Injection vincristine is an important component of therapy for acute lymphoblastic leukemia (ALL). An important adverse effect of vincristine is neurotoxicity. The incidence of this adverse effect is well studied. The present was undertaken to determine the incidence of vincristine-induced neurotoxicity in children with ALL after the induction of remission phase of chemotherapy and to ascertain its correlation with undernutrition, vitamin B12, folate and iron deficiency. Thirty children (1-18 years) with ALL were enrolled at the commencement of chemotherapy. The electrophysiological evaluation was done at baseline and repeated after four doses of vincristine (1.5 mg/m²/dose). Clinical evaluation was done regularly. Anthropometry and serum B12, folate and ferritin levels were assessed at baseline. Twelve children over a 4-week period of observation had peripheral neuropathy clinically. The autonomic system was most commonly involved followed by motor and sensory system respectively. On electrophysiological testing, half of the patients had evidence of neuropathy. Micronutrient deficiencies were present in a significant number of patients-63.3% had a B12 deficiency, 20% were deficient in folate and 43.3% in iron. The incidence of vincristine-induced neuropathy in patients with/without these micro-nutrient deficiencies was not statistically significantly different. Vincristine-induced neuropathy is common in Indian children with ALL. The present study did not find any correlation between the occurrences of vincristine-induced neuropathy and nutritional deficiencies. Larger studies are warranted to evaluate the contribution of micronutrient deficiencies to the development of peripheral neuropathy in childhood ALL.

Unusual Presentation of PMM2-Congenital Disorder of Glycosylation With Isolated Strokelike Episodes in a Young Girl

Congenital disorders of glycosylation (CDG) are multisystemic inherited metabolic disorders with marked phenotypic variability. The most frequent described type is PMM2-CDG (earlier known as CDG Type Ia) which presents either with pure neurologic features or with combined neurologic and systemic features. The classical presentation is characterized by varied combinations of developmental delay, hypotonia, ataxia, dysmorphism, inverted nipples, and abnormal fat distribution. Strokelike episodes and seizures are known acute complications that usually occur on a background of developmental delay, ataxia, or dysmorphism. We report here a developmentally normal young girl who presented with isolated strokelike episodes and was diagnosed to have CDG Type Ia. This condition should be kept in the differentials of unexplained strokelike episodes in children. The diagnosis has important therapeutic and prognostic implications.

Adverse Drug Reactions of Anti-Epileptic Drugs in Children with Epilepsy: A Cross-Sectional Study

Background:

Adverse drug reactions (ADRs) due to antiepileptic drugs (AEDs) in children contribute to poorer patient outcomes. However, reliable data ragarding such ADRs is not available.

Objectives:

Thus, the aim of the present study was to determine the incidence and patterns of ADRs of antiepileptic drugs in children aged 2-17 years presenting to a tertiary care teaching hospital.

Methods:

An observational study was conducted in the Department of Pediatrics, Kalawati Saran Children’s Hospital for a period of one year. Two hundred consecutive eligible patients (aged 2-17 yrs with epilepsy on AED) with consenting parents were enrolled. ADRs were noted using Paediatric Epilepsy Side Effect Questionnaire (PESQ) at clinic visits and any other ADRs reported by parents were also recorded. Causality, severity and avoidability assessments were done.

Results:

The mean age was 10.5 ± 3.6 years. A total of 139 ADRs occurred in 97 patients. One hundred and nine ADRs were reported by use of PESQ, in addition, 30 ADRs were reported by parents. Poor school result (33.8%) was the commonest ADR. Valproate (61.9%) was the main drug causing ADRs. Valproate, when used in polytherapy, was associated with more number of children experiencing ADRs (72.2%). The most common add on drug was clobazam (42.3%). Children with poorly controlled epilepsy were associated with more ADRs. Causality assessment revealed that 91.3% of the ADRs were probable. Most (94.9%) ADRs were of ‘mild’ category and 95.7% were probably preventable. Treatment was discontinued only in 6 patients of phenytoin toxicity.

Conclusion:

Cognitive and neurological problems were the most common ADRs seen in children with epilepsy. Polytherapy significantly increases the likelihood of ADRs in children.

Cerebral Palsy in North Indian Children: Clinico-etiological Profile and Comorbidities

Aims and Objectives

Cerebral palsy (CP) is a common motor disability in children. This study aimed at elaborating various comorbidities and etiologies and also at correlating motor disability with other disabilities.

Material and Methods

This hospital-based study was conducted in the outpatient department of a tertiary care hospital in Delhi on 160 children with CP in the age group 2-15 years. A detailed history taking and examination were conducted for each patient and appropriate investigations were performed.

Results

Most patients, that is 64.4%, were younger than 5 years of age and 72.5% were males. Most common etiology was birth asphyxia (41.9%). Maximum patients were of bilateral spastic (spastic quadriplegic) CP accounting 43.1%. Intellectual disability was the most common comorbidity across all subtypes of CP followed by epilepsy. Comorbidities such as epilepsy and all visual problems except optic atrophy were more common in spastic quadriplegic CP. Hearing, speech impairment, and optic atrophy were more common in dyskinetic CP. Chewing, swallowing, and drooling problems were more common in spastic quadriplegic CP.

Conclusion

Most common risk factor of CP is birth asphyxia; thus, by improving health care facilities, its incidence can be reduced. CP affects not only motor functions but also other important functions of body as well, and the more severe the motor disabilities, the more are other comorbidities and their intensity also increases with that of the intensity of brain insult.

Vitamin B12 Deficiency in Children With Infantile Spasms: A Case-Control Study

There have been few case reports showing association of vitamin B₁₂ deficiency with infantile spasms. We planned this study to see if there was an association of serum vitamin B₁₂ deficiency in children with development of infantile spasms. Cases included children with infantile spasms of ages 6 months to 3 years. The controls were children in the same age group who had global developmental delay but no history of epileptic spasms. Mean serum vitamin B₁₂, serum homocysteine, and urinary methylmalonic acid levels were measured in both groups and compared. Children with infantile spasms had lower mean serum vitamin B₁₂ levels (354.1 pg/mL; standard deviation 234.1 pg/mL) as compared to children with global developmental delay without spasms (466.7 pg/mL; standard deviation 285.5 pg/mL) ( P value < .05). Mean serum homocysteine level (13.9 vs 7.8 μmol/L, P = .02) and mean urinary methylmalonic acid level (68.1 mmol/mol of creatinine vs 26.1 mmol/mol of creatinine, P = .03) were elevated in children with infantile spasms than in controls. Fourteen children (35.0%) with infantile spasms were vitamin B₁₂ deficient compared with 3 (7.50%) controls ( P = .005). Thus, vitamin B₁₂ deficiency may have an association with infantile spasms. More studies are needed before recommending routine measurement of serum B₁₂ levels in children with infantile spasms.

Neurodevelopmental disorders in children aged 2-9 years: Population-based burden estimates across five regions in India

BACKGROUND

Neurodevelopmental disorders (NDDs) compromise the development and attainment of full social and economic potential at individual, family, community, and country levels. Paucity of data on NDDs slows down policy and programmatic action in most developing countries despite perceived high burden.

METHODS AND FINDINGS

We assessed 3,964 children (with almost equal number of boys and girls distributed in 2-<6 and 6-9 year age categories) identified from five geographically diverse populations in India using cluster sampling technique (probability proportionate to population size). These were from the North-Central, i.e., Palwal (N = 998; all rural, 16.4% non-Hindu, 25.3% from scheduled caste/tribe [SC-ST] [these are considered underserved communities who are eligible for affirmative action]); North, i.e., Kangra (N = 997; 91.6% rural, 3.7% non-Hindu, 25.3% SC-ST); East, i.e., Dhenkanal (N = 981; 89.8% rural, 1.2% non-Hindu, 38.0% SC-ST); South, i.e., Hyderabad (N = 495; all urban, 25.7% non-Hindu, 27.3% SC-ST) and West, i.e., North Goa (N = 493; 68.0% rural, 11.4% non-Hindu, 18.5% SC-ST). All children were assessed for vision impairment (VI), epilepsy (Epi), neuromotor impairments including cerebral palsy (NMI-CP), hearing impairment (HI), speech and language disorders, autism spectrum disorders (ASDs), and intellectual disability (ID). Furthermore, 6-9-year-old children were also assessed for attention deficit hyperactivity disorder (ADHD) and learning disorders (LDs). We standardized sample characteristics as per Census of India 2011 to arrive at district level and all-sites-pooled estimates. Site-specific prevalence of any of seven NDDs in 2-<6 year olds ranged from 2.9% (95% CI 1.6-5.5) to 18.7% (95% CI 14.7-23.6), and for any of nine NDDs in the 6-9-year-old children, from 6.5% (95% CI 4.6-9.1) to 18.5% (95% CI 15.3-22.3). Two or more NDDs were present in 0.4% (95% CI 0.1-1.7) to 4.3% (95% CI 2.2-8.2) in the younger age category and 0.7% (95% CI 0.2-2.0) to 5.3% (95% CI 3.3-8.2) in the older age category. All-site-pooled estimates for NDDs were 9.2% (95% CI 7.5-11.2) and 13.6% (95% CI 11.3-16.2) in children of 2-<6 and 6-9 year age categories, respectively, without significant difference according to gender, rural/urban residence, or religion; almost one-fifth of these children had more than one NDD. The pooled estimates for prevalence increased by up to three percentage points when these were adjusted for national rates of stunting or low birth weight (LBW). HI, ID, speech and language disorders, Epi, and LDs were the common NDDs across sites. Upon risk modelling, noninstitutional delivery, history of perinatal asphyxia, neonatal illness, postnatal neurological/brain infections, stunting, LBW/prematurity, and older age category (6-9 year) were significantly associated with NDDs. The study sample was underrepresentative of stunting and LBW and had a 15.6% refusal. These factors could be contributing to underestimation of the true NDD burden in our population.

CONCLUSIONS

The study identifies NDDs in children aged 2-9 years as a significant public health burden for India. HI was higher than and ASD prevalence comparable to the published global literature. Most risk factors of NDDs were modifiable and amenable to public health interventions.

Causality assessment of serious and severe adverse events following immunization in India: a 4-year practical experience

BACKGROUND

India has implemented the World Health Organization's revised Causality Assessment Protocol for adverse events following immunization (AEFI). We describe the number and types of serious/severe AEFIs, including deaths.

RESEARCH DESIGN AND METHODS

Analysis of causality classification of reported serious/severe AEFIs from 1 January 2012 to 7 January 2016 was done. Classification includes (A) consistent with causal association to immunization; (B) indeterminate; (C) coincidental association; or (D) unclassifiable. We present descriptive statistics across each category.

RESULTS

Analysis of causality assessment completed for 1037 reports of serious AEFIs: 499 (48%) were causally associated, 84 (8%) were indeterminate, 323 (31%) were coincidental, and 131 (13%) were unclassifiable. Of the 499 reports in the A category, the events were causally linked to vaccine product for 189 (18%), to immunization error for 135 (13%), and to immunization anxiety for 175 (17%). Among 279 reported deaths, more than half (55%; n = 153) were coincidental events and 37% were unclassifiable.

CONCLUSIONS

Causality assessment of AEFI cases is an important component of vaccination programs and post-marketing surveillance of vaccines. Field reporting and investigation of AEFIs can be improved for many severe or serious reports, most of which are not causally linked to the vaccination program.

Efficacy of Oral Zinc Supplementation in Radiologically Confirmed Pneumonia: Secondary Analysis of a Randomized Controlled Trial

OBJECTIVE

To evaluate the effect of zinc as an adjuvant therapy in radiologically confirmed pneumonia in children 2-24 months of age.

PATIENTS AND METHODS

We analyzed data of 212 children with pneumonia for whom chest X-ray films were available at enrollment and at least two radiologists agreed on the diagnosis of pneumonia. We compared the time to recovery in the two groups (n = 121, zinc group and n = 91, placebo group) using a Cox proportional hazards regression model.

RESULTS

Time to recovery was similar in both groups [median interquartile range: zinc, 84 h (64, 140 h); placebo, 85 h (65, 140 h)]. The absolute risk reduction for treatment failure was 5.2% (95% confidence interval: -4.8, 15.1) with zinc supplementation.

CONCLUSION

There was no significant beneficial effect of zinc on the duration of recovery or risk of treatment failure in children with radiologically confirmed pneumonia.

Changing pattern of prevalence, genetic diversity, and mixed infections of viruses associated with acute gastroenteritis in pediatric patients in New Delhi, India

There are very few studies that have assessed multiple viral agents causing Acute-Gastroenteritis (AGE) in India. The present study compared the changing pattern of prevalence and genetic diversity of five enteric viruses associated with acute-diarrhea in Delhi children within a gap of 5 years. Fecal samples were collected from diarrheal children (<4 years) during two winter seasons: year 2009-2010 (n = 59) and year 2014-2015 (n = 85). Samples were individually tested for rotavirus-A, norovirus, astrovirus, adenovirus, and sapovirus using EIA/RT-PCR and genetically characterized by phylogenetic analysis. Rotavirus was the most predominant (54.9%) virus followed by norovirus (25.7%), astrovirus (8.3%), and adenovirus (4.9%) with rare detection of sapovirus (0.7%). While detection rate increased for both rotavirus (49.2-58.8%) and astrovirus (5.1-10.6%), norovirus detection rate decreased (30.5-22.4%) from 2009 to 2015. During the same time period, adenovirus detection remained low (4.7-5.1%). Interestingly, mixed infections increased from 8.5% to 16.5% after 5 years. G1P[8] rotavirus strain was found most predominant (40%). Both type-1 and 8 astroviruses were detected. Single sapovirus detected was of genotype GII.1. Both GI (GI.5, GI.3) and GII (GII.1, GII.4, GII.7, GII.21, GII.13) genogroups of norovirus were detected. Of particular significance was the first detection of other NoV genotypes (besides GII.4 and GI.3) in Delhi. This is also the first report of NoV GI.5 from India. A change in prevalence pattern and increased diversity from 2009 to 2015 emphasizes the need for continued enteric virus surveillance to help measure the impact of new diarrhea vaccine(s) introduced in India.
