Efficacy of Teleconsultation-Based Rehabilitation in Children with Landry-Guillain-Barré Syndrome: An Open Label Randomized Controlled Trial (Tele Rehab-LGBS Trial)

OBJECTIVES

To evaluate the feasibility and efficacy of teleconsultation-based rehabilitation in children with Landry-Guillain-Barré syndrome (LGBS), measured with Medical Research Council (MRC) sum score and Hughes score.

METHODS

A pragmatic, prospective, parallel open label randomized controlled trial was conducted among a total of 50 children with LGBS. The children were randomized using computer generated block randomization into 2 groups (25 in each group): Standard of care (Group A) and teleconsultation-based rehabilitation (Group B). Primary and secondary outcomes were measured with MRC sum score and Hughes score at 12- and 24-wk follow-up.

RESULTS

The mean age was 6.4 ± 3.3 y; 29 (58%) were boys. Baseline MRC sum score (median, IQR), and Hughes score (median, IQR) in group A was 24 (7-31) and 5 (4-5) respectively; and in group B was 18 (9-24) and 4 (4-5) respectively. At discharge, median (IQR) MRC sum score in group A and B was 34 (28-41), and 30 (25-43) (p value = 0.31) respectively. Tele-rehabilitation was provided to group B for 24 wk with 96% compliance. At 12 wk, median MRC sum score in group A and group B were similar [48 (IQR 44-54) vs. 52 (IQR 46-60), p value = 0.08]. At 12 wk and 24 wk, median Hughes score in group A and B were similar. At 24 wk, 15 out of 23 subjects of group A and 18 out of 25 subjects of group B were ambulatory (p value = 0.61).

CONCLUSIONS

Teleconsultation-based rehabilitation was feasible with a high compliance rate. The functional outcomes measured with MRC sum score and Hughes score were similar in both the groups at 12 and 24 wk follow-up. Teleconsultation-based rehabilitation has similar efficacy as physical rehabilitation.

Zuranolone, a neuroactive drug, used in the treatment of postpartum depression by modulation of GABAA receptors

BACKGROUND

Postpartum depression [PPD] is a prevalent and debilitating mood disorder that affects mothers in the weeks to months after childbirth. Zuranolone (Zurzuvae) is a novel pharmaceutical agent that was approved by the US FDA on 4 August 2023 for the management of PPD. This review article provides a comprehensive overview of zuranolone, focusing on its dosing, chemistry, mechanism of action, clinical trials, adverse drug reaction, and overall conclusion regarding its utility in the management of PPD. It also discusses the recommended dosing strategies to achieve optimal efficacy while minimizing adverse effects as the dosage regimen of zuranolone is critical for its therapeutic application. Moreover, it gives insights into neurobiological pathways involved in PPD.

METHODOLOGY

Data from randomized controlled trials and observational studies was collected to provide a comprehensive understanding of zuranolone in the management and treatment of PPD.

CONCLUSION

Zuranolone represents a promising therapeutic option for women suffering from postpartum depression. However, ongoing research and post-marketing surveillance are essential to further elucidate its long-term safety and efficacy. The integration of zuranolone into clinical practice may significantly improve the quality of life for mothers facing the challenges of postpartum depression.

Evaluation of utility of Invasive Electroencephalography for definitive surgery in patients with Drug-Resistant epilepsy: A Systematic Review and Meta-analysis

When non-invasive tests are unable to define the epileptogenic zone in patients, intracranial electroencephalography (iEEG) is a method of localising the epileptogenic zone. Compared to non-invasive evaluations, it offers more precise information about patterns of epileptiform activity, which results in useful diagnostic information that supports surgical decision-making. The primary aim of the present study was to assess the utility of iEEG for definitive surgery for patients suffering from drug-resistant epilepsy (DRE). Online databases like PubMed, Medline, Embase, Scopus, Cochrane Library, Web of Science and IEEE explorer were searched for MeSH terms and free-text keywords. ROBINS I critical appraisal tool was used for quality assessment. Prevalence from different studies was pooled together using the inverse variance heterogeneity method. Eggers regression analysis and funnel plot were used to evaluate publication bias. The systematic review included eighteen studies, while the meta-analysis included ten studies to estimate the prevalence of seizure freedom (class I Engel) in patients undergoing surgery after iEEG. There were 526 patients in all that were included in the meta-analysis. The period of follow-up ranged from one to ten years. The overall pooled estimate of the prevalence of seizure freedom (class I Engel) in patients undergoing surgery after iEEG was 53% (95% CI: 44, 62). The results additionally demonstrated that twelve studies had a moderate risk of bias, whereas six studies had a low risk. Future studies are crucial to enhance our understanding of iEEG, guiding patient choices and unraveling their implications.

Familial hemiplegic migraine in Indian children-a tertiary center experience

Familial hemiplegic migraine (FHM), an autosomal dominant subtype of hemiplegic migraine, is a channelopathy presenting with severe headache, visual field defect, paresthesia, unilateral motor deficit, encephalopathy, seizures and aphasia. This cross-sectional study was conducted over 10 months in children aged 1-18 years suspected of hemiplegic migraine at a tertiary care pediatric hospital. Fourteen children were screened and five children with genetically confirmed FHM were included. The symptoms in the study population were paroxysmal hemiparesis (5/5), headache (5/5) and focal seizures (1/5). The hemiplegia episodes lasted from 4 h to 7 days. The mean age at the onset of neurological symptoms was 6.8 ± 0.7 years and the mean age at diagnosis was 12.8 ± 1.7 years, with a mean delay of 6.1 ± 1.9 years for the diagnosis. Neuroimaging during acute episodes revealed accentuated gray, white differentiation in the contralateral cerebral hemisphere with mild effacement of sulcal spaces in T2/fluid-attenuated inversion recovery (FLAIR) images. Genetic testing revealed ATP1A2 mutations (FHM2) in 4/5 and SCN1A (FHM3) in 1/5 patients. All of them (5/5) were initiated on oral topiramate and had favorable treatment responses with a mean follow-up duration of 7 ± 1.4 months. Diagnosis of FHM is mainly clinical and can be confirmed by genetic analysis. Perfusion and diffusion-weighted MRI should be considered during acute headache episodes, as it is mostly normal in symptom-free periods. Routine MRI sequences like T1 weighted, T2 weighted, FLAIR and contrast remain normal even during acute attacks.

Ameliorating effect of pioglitazone on prenatal valproic acid-induced behavioral and neurobiological abnormalities in autism spectrum disorder in rats

Autism spectrum disorder (ASD) is a neurodevelopment disorder that mainly arises due to abnormalities in different brain regions, resulting in behavioral deficits. Besides its diverse phenotypical features, ASD is associated with complex and varied etiology, presenting challenges in understanding its precise neuro-pathophysiology. Pioglitazone was reported to have a fundamental role in neuroprotection in various other neurological disorders. The present study aimed to investigate the therapeutic potential of pioglitazone in the prenatal valproic acid (VPA)-model of ASD in Wistar rats. Pregnant female Wistar rats received VPA on Embryonic day (E.D12.5) to induce autistic-like-behavioral and neurobiological alterations in their offspring. VPA-exposed rats presented core behavioral symptoms of ASD such as deficits in social interaction, poor spatial and learning behavior, increased anxiety, locomotory and repetitive activity, and decreased exploratory activity. Apart from these, VPA exposure also stimulated neurochemical and histopathological neurodegeneration in various brain regions. We administered three different doses of pioglitazone i.e., 2.5, 5, and 10 mg/kg in rats to assess various parameters. Of all the doses, our study highlighted that 10 mg/kg pioglitazone efficiently attenuated the autistic symptoms along with other neurochemical alterations such as oxidative stress, neuroinflammation, and apoptosis. Moreover, pioglitazone significantly attenuated the neurodegeneration by restoring the neuronal loss in the hippocampus and cerebellum. Taken together, our study suggests that pioglitazone exhibits therapeutic potential in alleviating behavioral abnormalities induced by prenatal VPA exposure in rats. However, further research is needed to fully understand and establish pioglitazone's effectiveness in treating ASD.

Primary Diffuse Leptomeningeal Melanomatosis in an Indian Child With Review of Literature

BACKGROUND

Primary diffuse leptomeningeal melanomatosis (PDLM) is an extremely rare, aggressive malignant neoplasia of the central nervous system. We report the first case of pediatric PDLM from India.

METHODS

A review of literature was done to describe the 15 pediatric cases reported so far.

RESULTS

A 12-year-old male child presented with fever, vomiting, and headache for 2 months. Cerebrospinal fluid examination was normal. An MRI of the brain revealed hydrocephalus, for which antitubercular therapy was started and external ventricular drainage followed by ventriculoperitoneal shunt was done. Repeat MRI revealed a suprasellar lesion, nodular enhancement of cranial nerves along with dural enhancement of spinal cord with arachnoiditis, and long-segment myelomalacia. Repeat cerebrospinal fluid examination was negative for malignant cells. During biopsy, blackish dura with diffuse blackish deposits in ventricle were noted. Histopathological examination revealed tumor cells with intracytoplasmic coarse brown pigment melanoma, frequent mitotic figures, and immunohistochemistry testing was positive for human melanoma black-45 and MelanA, suggestive of PDLM. He expired 4 months after the diagnosis.

CONCLUSION

Diagnosing PDLM can be daunting in light of its slow but malignant progression mimicking TBM leading to improper management. However, the absence of any supportive microbiological evidence and failure to respond to the standard antitubercular therapy with subsequent progression of the symptoms should prompt the need for finding an alternative diagnosis. A targeted molecular diagnosis and precision medicine may provide a favorable outcome in children with PDLM.

To Study the Distress, Anxiety, Depression, and Sleep Effects of the COVID-19 Pandemic on Essential Workers

Essential care workers like police personnel, social workers, and office and administrative staff of health institutions are also at increased risk of coronavirus disease 2019 (COVID-19) exposure along with healthcare workers. The present study aims to estimate the distress, anxiety, depression, and sleep impact of COVID-19 pandemic on essential workers through an online survey. This cross-sectional study (included 369 participants) was conducted in Chandigarh through an online survey using three psychological scales: Peritraumatic Distress Inventory (PDI), Insomnia Severity Index, and Depression Anxiety Stress Scale. Three-hundred-sixty-nine frontline warriors from hospital and community settings were included in the study. The respondents include police personnel (274; 73.66%), office staff (24; 6.45%), social workers (53; 14.24%), and media staff (21; 5.65%). Maximum distress was reported by media/transport officials on duty (85.7%). The majority of them scored high (>14), and slightly less than one-fourth (23.8%) scored significantly abnormal (>23) on PDI. About 42.9% reported moderate insomnia, 52.4% exhibited severe anxiety, and 33.3% of media/transport participants reported severe depression. Psychological morbidity is high in media/transport and social workers working in the community during the COVID-19 pandemic.

"Comparative evaluation of different chemical agents induced Autism Spectrum Disorder in experimental Wistar rats"

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with uncertain etiology and pathophysiology. Several studies revealed that the commonly used animal models like Valproic Acid (VPA) and Propionic Acid (PPA) do not precisely represent the disease as the human patient does. The current study was conducted on different chemically (VPA, PPA, Poly I:C, Dioxin (2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)) & Chlorpyrifos (CPF)) induced ASD-like animal models and validated the best suitable experimental animal model, which would closely resemble with clinical features of the ASD. This validated model might help to explore the pathophysiology of ASD. This study included rat pups prenatally exposed to VPA, PPA, Poly I:C, Dioxin & CPF within GD9 to GD15 doses. The model groups were validated through developmental and behavioral parameters, Gene Expressions, Oxidative Stress, and Pro-inflammatory and Anti-inflammatory cytokines levels. Developmental and neurobehavioral parameters showed significant changes in model groups compared to the control. In oxidative stress parameters and neuro-inflammatory cytokines levels, model groups exhibited high oxidative stress and neuro-inflammation compared to control groups. Gene expression profile of ASD-related genes showed significant downregulation in model groups compared to the control group. Moreover, the Poly I:C group showed more significant results than other model groups. The comparison of available ASD-like experimental animal models showed that the Poly I:C induced model represented the exact pathophysiology of ASD as the human patient does. Poly I:C was reported in the maternal immune system activation via the inflammatory cytokines pathway, altering embryonic development and causing ASD in neonates.

Teaching NeuroImage: Neuroimaging Features of Wilson Disease

A 13-year-old boy of nonconsanguineous parents presented with abnormal body movements, gait difficulty, and slurring of speech for 2 years. On examination, he had rigidity, dystonia, dysarthria, and drooling. Ophthalmologic examination revealed bilateral Kayser-Fleischer rings. He had elevated serum "free" copper levels (41.2 μg/dL [range:10-15]), 24-hour urine copper levels (895.7 μg/d [range:<60]), and reduced serum ceruloplasmin levels (4.3 mg/dL (range:20-40]). MRI revealed "face of giant panda" appearance (Figure A), T2-fluid attenuated inversion recovery hyperintensities (Figure, B and C), and frontal cystic encephalomalacic changes (Figure D), suggestive of Wilson disease (WD). Face of giant panda in WD, first described by Hitoshi et al.,1 is due to high signal intensity in tegmentum with normal signals in red nuclei forming the eyes, normal signals of pars reticulata (lateral portion) of substantia nigra forming the ears, and hypointensity of superior colliculus forming the chin.2 Bilateral cystic changes are less commonly reported in WD.3 Recognizing diverse neuroimaging signatures beyond well-known findings in WD enhances diagnostic accuracy.

Landscape of genetic infantile epileptic spasms syndrome-A multicenter cohort of 124 children from India

OBJECTIVE

Literature on the genotypic spectrum of Infantile Epileptic Spasms Syndrome (IESS) in children is scarce in developing countries. This multicentre collaboration evaluated the genotypic and phenotypic landscape of genetic IESS in Indian children.

METHODS

Between January 2021 and June 2022, this cross-sectional study was conducted at six centers in India. Children with genetically confirmed IESS, without definite structural-genetic and structural-metabolic etiology, were recruited and underwent detailed in-person assessment for phenotypic characterization. The multicentric data on the genotypic and phenotypic characteristics of genetic IESS were collated and analyzed.

RESULTS

Of 124 probands (60% boys, history of consanguinity in 15%) with genetic IESS, 105 had single gene disorders (104 nuclear and one mitochondrial), including one with concurrent triple repeat disorder (fragile X syndrome), and 19 had chromosomal disorders. Of 105 single gene disorders, 51 individual genes (92 variants including 25 novel) were identified. Nearly 85% of children with monogenic nuclear disorders had autosomal inheritance (dominant-55.2%, recessive-14.2%), while the rest had X-linked inheritance. Underlying chromosomal disorders included trisomy 21 (n = 14), Xq28 duplication (n = 2), and others (n = 3). Trisomy 21 (n = 14), ALDH7A1 (n = 10), SCN2A (n = 7), CDKL5 (n = 6), ALG13 (n = 5), KCNQ2 (n = 4), STXBP1 (n = 4), SCN1A (n = 4), NTRK2 (n = 4), and WWOX (n = 4) were the dominant single gene causes of genetic IESS. The median age at the onset of epileptic spasms (ES) and establishment of genetic diagnosis was 5 and 12 months, respectively. Pre-existing developmental delay (94.3%), early age at onset of ES (<6 months; 86.2%), central hypotonia (81.4%), facial dysmorphism (70.1%), microcephaly (77.4%), movement disorders (45.9%) and autistic features (42.7%) were remarkable clinical findings. Seizures other than epileptic spasms were observed in 83 children (66.9%). Pre-existing epilepsy syndrome was identified in 21 (16.9%). Nearly 60% had an initial response to hormonal therapy.

SIGNIFICANCE

Our study highlights a heterogenous genetic landscape and phenotypic pleiotropy in children with genetic IESS.

Neurodevelopmental Outcomes of a Cohort of Children with Tuberous Sclerosis Complex with Epileptic Spasms

The neurodevelopmental outcomes in children with tuberous sclerosis complex (TSC) with epileptic spasms remain underdiagnosed and might be responsible for significant morbidity and mortality burdens, even after spasms abate. The study was a cross-sectional study over 18 months at a tertiary care pediatric hospital, involving 30 children with TSC who had epileptic spasms. They were assessed with Diagnostic and Statistical Manual of Mental Disorders-5 criteria for autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and intellectual disability (ID), and childhood psychopathology measurement schedule (CPMS) for behavioral disorders. The median age at onset of epileptic spasms was 6.5 (1-12) months, and the age at enrolment was 5 (1-15) years. Of 30 children, 2 (6.7%) had only ADHD, 15 (50%) had only ID/GDD (global developmental delay), 4 (13.3%) had ASD and ID/GDD, 3 (10%) had ADHD and ID/GDD, and 6 (20%) had none. The median intelligence quotient/development quotient (IQ/DQ) score was 60.5 (20-105). CPMS assessment revealed significant behavioral abnormalities in almost half the children. Eight (26.7%) patients were completely seizure-free for at least 2 years, 8 (26.7%) had generalized tonic-clonic seizures, 11 (36.6%) had focal epilepsy, and 3 (10%) had evolved into Lennox-Gastaut syndrome. A high proportion of neurodevelopment disorders, including ASD, ADHD, ID/GDD, and behavioral disorders were seen in this pilot study with a small cohort of children with TSC with epileptic spasms.

A Randomized, Controlled, Noninferiority Trial Comparing Vitamin B12 Monotherapy Versus Combination Multinutrient Therapy with Vitamin B12 for Efficacy in Treatment of Infantile Tremor Syndrome

OBJECTIVES

To compare the mean Likert (caregiver impression of change) and CAPUTE scores in children with ITS treated with daily injectable vitamin B12 alone versus injectable vitamin B12 with other multinutrients at 1 wk and 1 mo of therapy.

METHODS

This was an open-label, active-controlled, assessor-blinded, noninferiority, randomized clinical trial. The participants included children aged 3 mo to 2 y with infantile tremor syndrome. Children were randomized to receive either 1 mg of daily injectable vitamin B12 or 1 mg of daily injectable vitamin B12 with other multinutrients (B12 + MV). Primary outcome measure was the mean Likert score in the two arms at 1 wk. Secondary outcome measures were mean change in CAPUTE scores at 1 wk of therapy; and mean change in CAPUTE and Vineland Social Maturity Scale (VSMS) scores after 1 mo of treatment.

RESULTS

Seventy-two (N = 72) of the 160 screened were enrolled and randomized. The mean (SD) Likert score in the B12 group (n = 38) was 16.1 (3.7) and in the B12 + MV group (n = 34) was 14.9 (3.7); p = 0.237. Mean (SD) change in CAPUTE (CAT/CLAMS) at 1 mo in the groups was not statistically different. The mean (SD) change in social quotient in the B12 monotherapy group, 35.0 (20.7) was significantly higher than the B12 + multinutrient group 23.5 (15.4); p=0.01.

CONCLUSION

Injectable vitamin B12 monotherapy in ITS resulted in an improvement that was noninferior to combination multinutrient therapy, strongly supporting vitamin B12 deficiency as the cause of infantile tremor syndrome.

TRIAL REGISTRATION

The trial was registered at CTRI.org (CTRI/2018/05/013841).

The Spectrum of Inherited Gray Matter Degenerative Brain Disorders (DBD) in Children: A Single-Center Study

Objectives

To study the clinical spectrum of inherited gray matter degenerative brain disorders (DBD) in children.

Methods

This cross-sectional study evaluated children up to 12 y of age, diagnosed with an inherited gray matter DBD in a tertiary care pediatric hospital between July 2019 and December 2020.

Results

A total of 314 children with progressive neuroregression were screened. Of these, 117 children with inherited gray matter DBD were included in the study. The clinic-based prevalence of DBD was 8.2%, and inherited gray matter DBD was 3.1%. The proportion of the inherited gray matter DBD was 37.3% among the overall DBD cases. Children were categorized into three groups based on the age at onset of disease: below 2 years (N = 57, 48.7%), between 2 and 5 years (N = 32, 27.3%), and between 6 and 12 years (N = 28, 23.9%). Based on the predominant cerebral structure involved, gray matter DBD were classified as cerebral gray matter disorders (53%), basal ganglia disorders (34.1%), and cerebellar disorders (12.8%). Overall, the most common disorders were Wilson disease (18%), neuronal ceroid lipofuscinosis (NCL) (17%), and neurodegeneration with brain iron accumulation (NBIA) (16%). The most common gray matter DBD in children <2 years of age were NBIA (n = 11), Rett syndrome (n = 11), and gangliosidoses (n = 10). NCL (n = 14) and ataxia telangiectasia (n = 6) were most common in the age group of 2-5 years. Wilson disease (n = 19) was the most common disorder in the age group of 6-12 years followed by NCL (n = 4) and NBIA (n = 3).

Conclusion

Our study highlights the burden and spectrum of gray matter DBD in children. The clinic-based prevalence of DBD was 8.2%, and of inherited gray matter DBD was 3.1%. The proportion of inherited gray matter DBD was 37.3% among the overall DBD cases. Wilson disease, NCL, and NBIA are the most common gray matter DBD in children. Timely diagnosis is important for the prevention of recurrence in subsequent pregnancies.

COVID-19 in Children with West Syndrome: An Ambispective Study

OBJECTIVES

To study the course of West syndrome (WS) and coronavirus disease-19 (COVID-19) in children with WS who contracted SARS-CoV-2 infection.

METHODS

This ambispective study was conducted at a tertiary-care center in North India between December 2020 and August 2021 after approval from the Institute Ethics Committee. Five children with WS, positive for COVID-19 based on RT-PCR, fulfilled the inclusion criteria.

RESULTS

One child with COVID-19 during the first wave was retrospectively included while four children (of the 70 children screened) were prospectively enrolled. The median age at onset of epileptic spasms was 7 mo (2 boys), and that at presentation with COVID-19 was 18.5 mo. Three had underlying acquired structural etiology. Three were in remission following standard therapy, while two had ongoing spasms at the time of COVID-19 illness. During the illness, two of those in remission continued to be in remission while one child had a relapse. The children with ongoing epileptic spasms had variable course [one had persistent spasms and other had transient cessation lasting 3 wk from day 2 of COVID-19 illness, but electroencephalography (on day 8 of COVID-19 illness) continued to show hypsarrhythmia]. Fever was the most typical symptom (and sometimes the only symptom) of COVID-19, with a duration ranging from 1-8 d. Two children had moderate COVID-19 illness requiring hospitalization, while the rest had a mild illness. All the affected children had complete recovery from COVID-19.

CONCLUSION

The severity of COVID-19 illness in children with WS is often mild, while the subsequent course of WS is variable.

Magnetic resonance imaging brain yield in developmental delay: A developing country perspective

BACKGROUND

Developmental delay (DD) is an important neuro-morbidity in children affecting the quality of life. MRI plays a crucial role by delineating the underlying structural, metabolic, and genetic abnormalities.

AIM

To determine the yield of MRI brain in delineating the various underlying abnormalities and etiological factors in children with DD and to correlate these findings with the clinical presentation.

METHODS

This cross-sectional study enrolled 50 children with the developmental delay between 6 months to 6 years of age.

OUTCOMES AND RESULTS

The mean age was 31.32 ± 20.56 months. The sensitivity of MRI was 72%. 81.3% of the children with microcephaly had abnormal MRI. The most common underlying etiology was hypoxic-ischemic encephalopathy (42%), followed by congenital/developmental defects and metabolic diseases (10% each). The most commonly involved region of the cerebral cortex was the occipital lobe (44%) because of the high occurrence of coexisting hypoglycemic brain injury, which is extremely common in developing countries and rare in developed countries, with 80% of them having visual abnormalities. Frontal lobe involvement was significantly more in children with abnormal motor findings and behavioral changes. Cortical grey matter abnormalities were significantly more in children with seizures.

CONCLUSION AND IMPLICATIONS

It is to be emphasized that children with developmental delays should be evaluated with MRI whenever possible. Apart from hypoxic-ischemic encephalopathy, other etiologies should also be looked for.

Predictors of Risk for Cerebral Palsy: A Review

PURPOSE

To identify the earliest predictors of risk for diagnosis of cerebral palsy (CP).

METHODS

A comprehensive literature search was conducted using various databases. The publications were reviewed to identify risk factors for CP from conception to early infancy. Studies were critically appraised with Joanna Briggs Institute guidelines for quality appraisal and evaluated for risk of bias using the Agency for Health Care Research and Quality guidelines.

RESULTS

The initial search yielded 129 studies and 20 studies were included. Forty-seven risk factors for CP were extracted of which several were duplicate terms. The significant risk factors found to be indicative of CP were low birth weight (<1500 g), birth at less than 28 weeks of gestational age, periventricular leukomalacia, grade 3 or 4 intraventricular hemorrhage, preeclampsia, prematurity, an Apgar score of less than 4 at the first minute, birth asphyxia, preterm premature rupture of membrane, and absent fidgety movements.

CONCLUSION

Twenty-three factors were consistently reported as predictors of CP.

Clinical Profile, Follow-up, and Role of Neuroimaging in Pediatric Guillain-Barré Syndrome in the COVID Era: An Ambispective Study

Background: To define the varied presentations of Guillain-Barré syndrome in children in the COVID era and 6 months' follow-up outcome. Methods: Ambispective study of 15 months' duration involving children with Guillain-Barré syndrome aged 1 month to 18 years at a tertiary care pediatric hospital. They were categorized into groups A and B based on COVID-19 serology testing. Hughes Disability Scale was used for disability assessment. Modified Rankin scale was used for improvement assessment in follow-up. Results: Of 19 children with Guillain-Barré syndrome, 9 (47%) were females and 10 (53%) were males. Groups A and B had children with negative (8) and positive serology (11), respectively. The most common presentation in both groups was motor weakness. Post-COVID pediatric Guillain-Barré syndrome presented with variants of Guillain-Barré syndrome rather than the classical form (P = .03). In group B, patients with elevated inflammatory markers had poor response to intravenous immunoglobulin, and 5 of 11 patients had good response to pulse steroids, probably depicting an inflammation-predominant pathology. Conclusion: Post-COVID Guillain-Barré syndrome in children presented with Guillain-Barré syndrome variants rather than the classic form. Neuroimaging is of great value in both confirming Guillain-Barré syndrome diagnosis and excluding differentials. Patients with elevated inflammatory markers and residual weakness may be given a pulse steroid trial.

Paroxysmal Neuropathic Pruritus in Patients With Chiari Malformation Type I: A Rare Phenotype

Chiari malformation type I (CM-I) is a group of deformities in the posterior fossa and hindbrain, including the pons, cerebellum, and medulla oblongata. Paroxysmal pruritus in CM-I has been reported only once before in the literature. This study was a cross-sectional study over 12 months at a tertiary care pediatric hospital involving children aged one to 18 years with CM-I presenting with paroxysmal itching. Three patients with CM-I presented with severe episodes of paroxysmal itching. Patient 3 was started on carbamazepine therapy for seizures, and incidentally, his itching subsided. The pruritus of neuropathic etiology has been reported to be associated with syringomyelia, spongiform encephalopathies, autoimmune disorders like multiple sclerosis, patients with end-stage renal failure on dialysis, and neoplasms. Antihistamines and antiallergics are ineffective in treating these patients, reiterating a central mechanism for pruritus. At present, no drugs have been approved for the treatment of neuropathic pruritus specifically. The commonly used treatments for neuropathic itch are antiseizure medications, tricyclic antidepressants, gabapentinoids, ketamine, and oral kappa opioids, including butorphanol and difelikefalin. Better structured prospective studies are needed to analyze the prevalence and scales to assess disability caused due to neuropathic itch in CM and may enhance understanding in this area.

Mental health of health care workers during the hour of crisis - A study from tertiary care hospital in North India

Background and Aims

This cross-sectional study aimed to analyze the psychosocial, behavioral, and sleep impact of coronavirus disease-19 (COVID-19) pandemic on healthcare workers (HCWs) at a tertiary-care hospital in Northern India.

Materials and Methods

An online questionnaire including three psychological scales - peritraumatic distress inventory (PDI), insomnia Severity Index (ISI), and Depression anxiety stress scale was circulated among the HCWs at a tertiary-care hospital in Northern India.

Results

Three hundred and ninety-six HCWs (Mean age standard deviation: 34.8 [8.1%] years; 181 females) responded. Place of posting was active COVID area (27.2%), reserve active COVID team (23.2%), trained reserve pool (29.5%), and non-COVID areas (19.9%). More than half of all the respondents (51%) had abnormal PDI score (>14) with a propensity to develop posttraumatic stress disorder. Furthermore, there was a significantly higher prevalence of abnormal PDI scores in those involved in active COVID care units (74%) versus non-COVID care unit (24%, P = 0.001). More than 60% of all the respondents had abnormal ISI score suggesting significant insomnia. Stress was seen in 71% of all the respondents while 82% were anxious and 77% participants had depressive symptoms. Hence, the psychological morbidity among the HCWs was high.

Conclusion

Our study found a much higher prevalence of peritraumatic distress, insomnia, anxiety, stress, and depression among the HCWs, more so in those working in COVID areas. Factors indigenous to Indian population in terms of psychological health must be studied and addressed to reduce this psychological morbidity since the battle with COVID is long.

Late Onset Pompe's Disease: Clinical, Pathological &amp; Molecular Analysis of Two Adolescent Patients

INTRODUCTION

The estimated global prevalence of late onset Pompe's disease is 1/57000 live birth(1). We present the case of two patients diagnosed to have Pompe's disease with a rare association of cardiomyopathy.

MATERIALS

Two siblings born out of non consanguineous marriage presented with proximal myopathy of 5 years duration. Patient 1 - 19 year female, there was atrophy and weakness of face, neck, girdle and limbs. Her Echocardiogram showed LV dilation with low ejection fraction, ECG showed LV hypertrophy with incomplete LBBB. Her CK-NAC values came to be 918 U/L. Patient 2 - 16 year male; progression, distribution and severity slightly different to his sister but had exertional dyspnea since last one year. His echocardiogram showed LV diastolic dysfunction, ECG showed short PR interval partial LBBB and his CK-NAC came to be 2347 U/L. His skeletal muscle biopsy showed deposition of glycogen. Genetic analysis revealed pathogenic mutation in GAA gene (c.2040G&gt;A) in both patients.

RESULT

Late onset Pompe disease is of less severity but progressive. The involvement of heart is less likely compared to infantile onset(2). It is also interesting that the same variant presents differently in both patients.

CONCLUSION

Genetic diseases manifest as rare phenotype which in itself is a clinical puzzle. When rare disease present with a rare manifestation of itself, this pose a great diagnostic challenge. Pompe's disease is one of the very few inherited disorder which has definitive treatment- enzyme replacement therapy.

Limb Hypertrophy—An Uncommon Presentation Yet a Common Link among Neurocutaneous Syndromes: A Series of Three Cases

Limb hypertrophy is an unusual presentation associated with neurocutaneous syndromes. The mechanism behind this presentation may vary from case to case. Here, we describe a case series of three different syndromes linked by a common clinical finding of limb hypertrophy.

Charcot-Marie-Tooth Disease Type 4C and Autosomal Dominant Heterozygous Ichthyosis Vulgaris, with Bilateral Hearing Loss: A Novel Association with Review of Literature

A 3-year-old boy, firstborn to nonconsanguineous parents, presented with motor development delay and floppiness of bilateral lower limbs since birth. No significant family history presented at time of check-up. He could stand with support, eat with a spoon without spillage, and speak in two-word sentences. There was no history suggestive of cranial nerve impairment. Examination revealed normal head circumference, dry, scaly skin lesions on the trunk, distal weakness with sluggish deep tendon reflexes in bilateral lower limbs, and a high stepping gait. Nerve conduction studies revealed demyelinating polyneuropathy. Brain stem-evoked response audiometry testing revealed auditory neuropathy. Clinical exome sequencing revealed a known pathogenic variant of 3325C > T in the SH3TC2 gene suggestive of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris with a novel variant of 2218C > T in the FLG gene. We have reviewed the available literature for reported associations of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris. This is probably the first reported association of Charcot-Marie-Tooth disease type 4C and ichthyosis vulgaris with bilateral hearing loss.

Restricted and Repetitive Behaviors and Interests in Young Children with Autism: A Comparative Study

OBJECTIVES

To examine the frequency of repetitive behaviors among children with autism spectrum disorder (ASD) and compare it to age-matched developmentally delayed (DD) and typically developing children (TD).

METHODS

Twenty-five children (3-8 y) with a diagnosis of ASD were compared to two age-matched control groups namely the DD and TD groups. The Repetitive Behaviors Scale-Revised (RBS-R) was administered to the parents to assess the frequency, severity, and impairment associated with restricted, repetitive behaviors, and interests (RRBIs) displayed. The study was cleared by the institute ethics committee.

RESULTS

The three groups were well matched on age and sex distribution and comparisons on the RBS-R showed that the ASD group had a significantly higher total score (F = 51.52, p = 0.0001) and number of items endorsed on the scale (F = 37.91, p = 0.0001). Stepwise multiple regression analysis revealed that 35.8% of the variance in the total RRBI score of the ASD children was explained by the age and severity of autism (F = 6.12. p = .008). Older children with severe ASD features had significantly higher total RRBI scores.

CONCLUSIONS

RRBIs are not just specific to autism and should not be used in isolation to identify children with autism. Gaining a complete understanding of the complexity and variability of the restricted interests would help in improving the diagnostic procedures and in the development of a comprehensive therapeutic plan.

Normative Values for Auditory Brainstem Responses and Wave V Thresholds in Indian Neonates and Infants

Click-evoked auditory-brainstem-response (ABR) is widely used for hearing screening in neonates and infants. However, their normative values are based on small studies. This retrospective study was done at a tertiary-care centre where click-ABR based screening is done in all newborns. ABR records (Nihon-Kohden machine, model MEB-9400K) of 420 healthy neonates (preterm 75; full-term 32) and infants (113) done over a period 4 years (2014-2018) were analysed retrospectively. Sick neonates and those with Wave V threshold > 40 dbnHL were excluded. Infants were divided into four groups based on post-conceptual age, Group A (75): 34-36 weeks; Group B (44): 37-40weeks; Group C (188):41 weeks-1 month; and Group D (113): 1-6months. The mean absolute latencies for wave I, wave III, and wave V varied from 1.45-1.56 milliseconds (ms), 4.14-4.37 ms, and 6.36-6.81 ms respectively. Interpeak latencies for I-V and I-III varied from 4.91 ms to 5.22 ms and 2.69 ms to 2.81 ms respectively. Older infants had lower absolute and interpeak latencies. Late preterm babies were not different from term babies suggesting early maturation of brainstem pathways.

Ptosis, Visual Blurring, and Multiple Cranial Nerve Tumors: Do We Know the Culprit

Neurofibromatosis type 2 (NF2) is a monogenic condition caused by mutations in the NF2 gene. Examination of skin and eyes and parental screening play a key role in the diagnosis of pediatric NF2. We report a four-year-old boy, who presented sub-acutely with unilateral vision loss, ptosis and exotropia with a positive family history of NF2.

Post-COVID-19 Immune-Mediated Neurological Complications in Children: An Ambispective Study

BACKGROUND

The neurological manifestation following a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is varied, and till now, only a few studies have reported the same.

METHODS

We used retrospective data from May to July 2021 and prospective study data from August to September 2021, including that from children aged between one month and 18 years who presented to a tertiary care referral center with the neurological manifestation and had a history of coronavirus disease 2019 (COVID-19) infection or exposure and positive SARS-CoV-2 serology. The neuroradiological manifestations were further categorized as in a predesigned proforma.

RESULTS

Case records of the 18 children who fulfilled the criteria were included in the study; among them, seven (38.8%) were male and 11 (61.1%) were female. Predominant presentation in our study group was status epilepticus (six of 18) and Guillain-Barré syndrome (five of 18). Other manifestations included stroke (two of 18), demyelinating syndromes (three of 18), and autoimmune encephalitis (two of 18). Most of the children had favorable outcomes except for one mortality in our cohort.

CONCLUSIONS

Delayed complications following SARS-CoV-2 infection are seen in children. A temporal correlation was noted between the COVID-19 infection and the increasing number of neurological cases after the second wave. Steroids could be beneficial while treating such patients, especially in the presence of high inflammatory markers. Testing for SARS-CoV-2 serology during the pandemic can give a clue to the underlying etiology. Further multicentric studies are required to understand the varied neurological manifestations following SARS-CoV-2 infection in children.
