RESUMO
The purpose of this study was to compare the efficacy of oral triclofos (TRI), intranasal midazolam (INM), and intranasal dexmedetomidine (IND) in achieving successful sedation in children undergoing MRI. This open-label, three-arm, randomized trial was conducted in a tertiary care teaching hospital over 18-month period. Children scheduled for MRI were enrolled. Rate of successful/adequate sedation was assessed using the Paediatric Sedation State Scale (PSSS). The primary outcome was the efficacy (successful sedation or sedation rate) of the three drugs. One-hundred and ninety-five children were included for the MRI procedure. IND was found to be superior in terms of achieving successful sedation. INM had a shorter onset and duration of sedation compared to IND and TRI, but with an increased failure rate (88.3%). Keeping INM as the reference group, it was found that the odds of sedation increased 4.1 times on changing from INM to IND (p < 0.01), and 2.26 times on changing from INM to TRI (p < 0.01). Adverse events included nasal discomfort (18.3%) in INM group; and self-limited tachycardia (4.6%) and hypotension (10.8%) in the IND group. CONCLUSION: IND was more efficacious than INM or TRI for procedural sedation in children undergoing MRI without any significant adverse events. CLINICAL TRIAL REGISTRATION: CTRI/2019/01/017257; date registered: 25/01/2019. WHAT IS KNOWN: ⢠Oral triclofos (TRI) and intranasal midazolam (INM) have been used for procedural sedation in children undergoing MRI with variable success; but the experience with intranasal dexmedetomidine (IND) is limited. WHAT IS NEW: ⢠IND provides more effective sedation compared to INM or TRI for procedural sedation in children undergoing MRI, without any significant adverse events.

BACKGROUND: The effects of drastic curricular changes necessitated by the COVID-19 pandemic on medical students' education and wellbeing have remained largely unstudied. Out study aimed to characterize how medical students were affected by the pandemic, specifically how limitations introduced by the pandemic may have affected the quality, delivery, and experience of medical education. METHODS: Three hundred students from 5 U.S. allopathic medical schools were surveyed to determine students' perceptions about their quality of medical education, professional development, and mental health during the COVID-19 pandemic (October 2020-December 2020). RESULTS: A large majority of students report that while lecture-based learning has not been significantly affected by the pandemic, small-group and clinical learning have greatly declined in quality. Students also reported higher levels of depression, anxiety, and uncertainty with regards to their futures as physicians. CONCLUSIONS: The COVID-19 pandemic has greatly affected the medical student education and wellbeing. Although medical schools have implemented measures to continue to train medical students as effectively as they can, further strategies must be devised to ensure the well-being of students in the present and for future national emergencies.

Longitudinal extensive transverse myelitis (LETM) is a rare form of widespread inflammation of the spinal cord causing T2 hyperintensity in spinal magnetic resonance imaging (MRI) extending across three or more vertebral segments. It is an acute onset of sensory, motor, and autonomic dysfunction of variable etiology with a likely poor outcome. We present a case series of three cases wherein children between the ages of 4 and 13 years had diverse symptoms from gradual painless loss of vision in both eyes with headache, vomiting and seizure, and a normal central nervous system examination except involvement of the optic nerve to another child with abdominal pain, urinary retention and constipation for 3 days with exaggerated DTR, and patchy sensory loss without any definite sensory level, and to the third child with fever and weakness of lower limbs, hypotonia and grade 1-2/5 power in lower limbs and normal upper limb power. Contrast-enhanced MRI spine of all children showed long segment T2 hyperintensity with variable involvement of the brain. The first two children were treated with pulsed dose methylprednisolone, and the last child received intravenous immunoglobulin followed by methylprednisolone. All were followed with oral prednisolone. LETM has a varied presentation with different etiologies. Antineuromyelitis optica immunoglobulin G (IgG) antibody (Aquaporin-4 IgG) and antimyelin oligodendrocyte glycoprotein antibody are strongly recommended though they may not be locally available or not affordable. Early and aggressive immunomodulatory therapy may help faster recovery, as did with two of our three children.
RESUMO
We present a one-year old, developmentally normal toddler from a non Agarwal community, who presented to us with only a large head. The examination findings were unremarkable except a large head circumference. Neuroimaging confirmed the diagnosis of megalencephalic leukoencephalopathy (MLC). Although developmental delay and seizures are common manifestations in MLC, we want to highlight the fact that many children like ours may have no neurological manifestations at all which makes it necessary to do neuroimaging to establish the diagnosis and offer genetic testing for confirmation of the same.
RESUMO
Dyke-Davidoff-Masson syndrome is a rare disease of childhood which is clinically characterized by hemiparesis, refractory seizures, facial asymmetry, and mental retardation. The classical radiological findings are cerebral hemiatrophy, calvarial thickening, and hyperpneumatization of the frontal sinuses. Seizure refractory to medical management warrants surgical intervention with excellent outcome. Here, we are reporting two such cases who presented late and diagnosis was made on the basis of magnetic resonance imaging brain features. Both of our children responded to oral anticonvulsant and are on regular follow-up.
RESUMO
The aim of this article was to study the spectrum of scrub typhus meningitis/meningoencephalitis (STM) cases in children. Children ≤14 years of age with acute undifferentiated febrile illness were included. Immunoglobulin M (IgM) enzyme-linked immunosorbent assay was done in blood and cerebrospinal fluid (CSF) of children with suspected STM. Demographic, clinical, and laboratory details were expressed as descriptive statistics. Factors associated with neurological involvement were identified on univariate analysis. A total of 76 children had ST during the study period (meningitis/meningoencephalitis = 8 [10.5%], of which 5 [62.5%] had detectable ST IgM antibodies in CSF). The included children were 4 to 12 years of age with boys > girls. Headache and vomiting were common in those with STM, whereas hyponatremia and thrombocytopenia were common in those without STM. All children with STM recovered with sequelae in one child (right lateral rectus palsy). There was no mortality. STM has an incidence of 10.5% in children with ST from Eastern India. Headache and vomiting were significant predictors of STM, whereas hyponatremia and thrombocytopenia were significant predictor of non-STM.
