Abstract Background During the current pandemic, there is an increased incidence of neurologic/neuropsychiatric manifestations in patients with the novel coronavirus (COVID-19). Neurologic manifestations may be coincident or result of disease and its therapy. In the emergency department, orientation of the clinician with this issue is crucial for accurate decision making to limit the spread of infection during neurologic treatment. This study aimed to be familiar with MRI findings in patients with Neuro-COVID. Seventy patients presented with neurologic/neuropsychiatric manifestation either post COVID or during hospitalization underwent cerebral MRI from April 2020 to June 2021 (39 men and 31women; mean age 43.27, age range from 16 to 69 years). Results Headache (80%), is the most prevalent neurological manifestations followed by smell and taste impairment (62.9%) and stroke symptoms (45.7%). Low mood and anxiety (17.1%), prolonged fatigue (14.3%) and depression (7.1%) are the most common psychiatric symptoms. Infarctions, hematoma and demyelinating disease are the most prevalent findings. There is a week positive correlation between MRI findings and CT chest finding but without statistical significance (P-value 0.2). Conclusions Cerebrovascular disease and demyelinating lesions are common manifestations of COVID 19. Familiarity of neurologists and radiologist in the emergency department and in-patient with this issue is crucial to avoid misdiagnosis and the spread of infection.

Balo’s concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as “onion bulb.” We present a case of BCS and discuss the imaging findings and management strategies of this disease. A 26-y-old male developed headache, weakness, and numbness of limbs. Magnetic resonance imaging (MRI) showed concentric lamellar like demyelinating lesions at the subcortical regions. The patient’s neurological symptoms were consistent with the MRI findings.

Abstract Objective Japanese encephalitis (JE) is an arthropod-borne flavivirus infection having high mortality and morbidity. This study was performed to evaluate the conventional magnetic resonance imaging (MRI) findings in JE and to find out any difference between pediatric and adult JE. Materials and Methods This retrospective study was performed on serologically positive 54 JE patients presented to a tertiary care hospital with acute encephalitic symptoms between April 2016 and October 2019. Relevant neurological examination, cerebrospinal fluid analysis, and MRI scan of the brain were performed. Results Fifty-four JE patients (n = 31 males and n = 23 females) having 32 pediatric and 22 adult JE were included in the study sample. Group 1 JE (n = 16) patients had encephalitic symptoms with duration less than 15 days up to the day of MRI scan and group 2 JE (n = 38) had symptoms more than 15 days. Group 1 JE had mean apparent diffusion coefficient (ADC) value of 0.563 ± 0.109 (standard deviation [SD]) × 10–3 mm2/sec and group 2 JE had 1.095 ± 0.206 (SD) × 10–3 mm2/sec. The mean ADC value of pediatric JE was 0.907 ± 0.336 (SD) × 10–3 mm2/sec and adult JE was 0.982 ± 0.253 (SD) × 10–3 mm2/sec. Conclusion The majority of the JE patient shows abnormal signal alterations in bilateral thalami and substantia nigra. Diffusion-weighted imaging with ADC mapping helps in evaluating the stage of the JE. No statistical significance of the various conventional MRI findings was found between the pediatric JE and adult JE.

AbstractObjectives: Clinical neuroscience is increasingly turning to imaging the human brain for answers to a range of questions and challenges. To date, the majority of studies have focused on the neural basis of current psychiatric symptoms, which can facilitate the identification of neurobiological markers for diagnosis. However, the increasing availability and feasibility of using imaging modalities, such as diffusion imaging and resting-state fMRI, enable longitudinal mapping of brain development. This shift in the field is opening the possibility of identifying predictive markers of risk or prognosis, and also represents a critical missing element for efforts to promote personalized or individualized medicine in psychiatry (i.e., stratified psychiatry). Methods: The present work provides a selective review of potentially high-yield populations for longitudinal examination with MRI, based upon our understanding of risk from epidemiologic studies and initial MRI findings. Results: Our discussion is organized into three topic areas: (1) practical considerations for establishing temporal precedence in psychiatric research; (2) readiness of the field for conducting longitudinal MRI, particularly for neurodevelopmental questions; and (3) illustrations of high-yield populations and time windows for examination that can be used to rapidly generate meaningful and useful data. Particular emphasis is placed on the implementation of time-appropriate, developmentally informed longitudinal designs, capable of facilitating the identification of biomarkers predictive of risk and prognosis. Conclusions: Strategic longitudinal examination of the brain at-risk has the potential to bring the concepts of early intervention and prevention to psychiatry. (JINS, 2016, 22, 164–179)

Objective: To examine the clinical relevance of isolated pontine hyperintense lesions(PHLs) on MRI in patients with atherosclerosis.Methods: Seventeen atherosclerotic patients with isolated PHL on MRI were compared with 17 patients without PHL and were matched for age, sex, and initial manifestation of atherosclerosis. Subjects and observer were blinded to the MRI findings. We assessed symptoms, impairment, and disability with a structured interview and neurologic examination as well as disability scales.Results: On all items, patients with PHL scored worse that did their controls. We found the largest differences in frequencies of symptoms of disequilibrium, difficulties with speech or swallowing, the Timed Walking Test, and the body care and movement subscale of the Sickness Impact Profile. Except for disequilibrium (p = 0.04), these differences did not reach statistical significance. Abnormal tandem-walking tests were more frequent in patients than they were in controls. Pyramidal signs were equally distributed.Conclusions: We propose PHL as a cause of symptoms of disequilibrium in patients with atherosclerosis. Symptoms are probably elicited by dysfunction of the corticopontine fibers, the pontocerebellar fibers, or the pontine nuclei.

Patient was followed up over the course of 30 years. In 1978, after severe systemic infection followed by fever, pulmonary edema, and numerous neurological manifestations, patient was differentially diagnosed with apoplectic form of multiple sclerosis (MS), which was confirmed a year later via neurological and MRI findings. Approximately 20 years following the initial attack, sarcoidosis was diagnosed during the regular preoperative procedures required for cataract surgery. As consequence of lower immune system, infectious granulomatosis in form of pulmonary tuberculosis developed. Ophthalmological findings revealed bilateral retrobulbar neuritis (RBN) approximately six years after initial attack. This developed into total uveitis with retinal periphlebitis and anterior granulomatous uveitis—all of which are clinically similar in both MS and sarcoidosis.

False tooth extraction (FTE), a cultural practice in East Africa used to treat fever and diarrhea in infants, has been thought to increase infant mortality. The mortality of clinically similar infants with and without false tooth extraction has not previously been examined. The objective of our retrospective cohort study was to examine the mortality, clinical presentation, and treatment of infants with and without false tooth extraction. We conducted a retrospective chart review of records of infants with diarrhea, sepsis, dehydration, and fever in a rural Ugandan emergency department. Univariate analysis was used to test statistical significance. We found the mortality of infants with false tooth extraction (FTE+) was 18% and without false tooth extraction (FTE−) was 14% (P=0.22). The FTE+ study group, and FTE− comparison group, had similar proportions of infants with abnormal heart rate and with hypoxia. There was a significant difference in the portion of infants that received antibiotics (P=0.001), and fluid bolus (P=0.002). Although FTE+ infants had clinically similar ED presentations to FTE− infants, the FTE+ infants were significantly more likely to receive emergency department interventions, and had a higher mortality than FTE− infants.

We present a 1-year-old boy who presented to the emergency department with a 7-day history of diarrhoea and vomiting. The initial renal function profile demonstrated a urea of 55 mmol l−1 (normal range between 5 and 20 mmol l−1), creatinine 695 micromol/L (normal range between 62–106 micromol/L) and potassium 9.1 mmol l−1 (normal range between 3.5–5.0 mmol l−1), with a profound metabolic acidosis. Upon examination, there were no significant findings, specifically no neurological abnormality. He was prescribed back-to-back Salbutamol nebulisers, to increase the shift of extracellular potassium into the intracellular space, followed by i.v. calcium gluconate, with some improvement in potassium levels. A further 5 mmol of sodium bicarbonate was given, as well as a stat dose of 1 mg/kg furosemide, and per rectal calcium resonium. He was then commenced on an infusion with 10% dextrose with insulin. He was subsequently found to be in urinary retention and a catheter was inserted, which drained 1700 ml. A subsequent renal function profile, 24 hours after admission, demonstrated improvement with urea 39 mmol l−1, creatinine 300 micromol/L and potassium 3.0 mEq/L.

Long Term Prognosis

Abstract The long-term prognosis of fetus with cardiac rhabdomyoma (CR) depends on the correlation with tuberous sclerosis complex(TSC). Recent years, numerous variations of uncertain significance (VUS) of TSC genes produced by high-throughput sequencing makes counseling challenging, studies until now tend to sidestep the tricky topics. Here, we integrated detailed parental phenotype, echocardiography, neuro MRI and genetic information to conduct a comprehensive evaluation for 61 CR fetuses. As a result, multiple CRs and cerebral lesions appeared in 90% and 80% respectively in fetuses with pathogenic(P)/likely pathogenic(LP) TSC1/TSC2 variation. 85.7% of the live-born with P/LP presented TSC-associated signs. 85.7% VUS without nervous findings had good prognosis. Genetic evidence and cerebral MRI findings are the most sensitive index to assess long-term prognosis, which complement and confirm each other for a TSC diagnosis. 68.9% fetuses with CR could benefit from this multidisciplinary approach, which turned to be potentially clinically actionable with precise clinical/genetic diagnosis or had a foreseeable outcome. Our practice provides a practical and feasible solution for perinatal management and prognostic guidance for fetuses with CR.

Eligibility Assessment

The new McDonald diagnostic criteria for multiple sclerosis (MS) incorporate detailed criteria for the interpretation and classification of magnetic resonance imaging (MRI) findings, but, in contrast, provide no instructions for the interpretation of clinical findings. Because MS according to the McDonald criteria is one of the primary endpoints in a large trial enrolling patients after the first manifestation suggestive for a demyelinating disease (BENEFIT study), it was decided to organize a centralized eligibility assessment for this trial. During this eligibility assessment it was observed that there were marked inconsistencies in the decisions of participating neurologists with respect to the classification of clinical symptoms as being caused by one or more lesions provoking discussions in about one in every five patients. This paper describes these inconsistencies and their sources, and recommends a systematic approach that attempts to reduce the variability in interpreting clinical findings.
