Idiopathic intracranial hypertension associated with SARS-CoV-2 infection in an adult male patient: a case report and review of the literature

BackgroundHeadache is a frequent symptom in coronavirus disease 2019 (COVID-19) patients, and idiopathic intracranial hypertension (pseudotumor cerebri) has been reported among patients who underwent lumbar puncture for persistent headaches.Case presentationA 45-year-old black man presented with dyspnea, cough, fever and headache for 05 days followed by blurring of vision associated with worsening of the headache. Physical examination was significant for tachypnea and oxygen desaturation and there were no abnormal neurologic findings. He tested positive for SARS-CoV-2 with nasopharyngeal swab PCR. His CSF opening pressure appeared high with normal CSF analysis and brain magnetic resonance imaging (MRI) revealed prominent subarachnoid space around the optic nerves and bilateral papilledema. He had significant improvement with medical therapy alone.ConclusionIdiopathic intracranial hypertension (IIH) may occur in association with SARS-CoV-2 infection and should be considered when making a differential diagnosis for headache and blurring of vision. COVID-19 may play a role in the development of intracranial hypertension, even in the absence of known risk factors. Early diagnosis and treatment of IIH has paramount importance to prevent vision loss and other morbidities.

Evaluation of the Patients with the Diagnosis of Pontocerebellar Hypoplasia: A Multicenter National Study.

Pontocerebellar hypoplasia (PCH) is a heterogeneous group of neurodegenerative disorders characterized by hypoplasia and degeneration of the cerebellum and pons. We aimed to identify the clinical, laboratory, and imaging findings of the patients with diagnosed PCH with confirmed genetic analysis. We collected available clinical data, laboratory, and imaging findings in our retrospective multicenter national study of 64 patients with PCH in Turkey. The genetic analysis included the whole-exome sequencing (WES), targeted next-generation sequencing (NGS), or single gene analysis. Sixty-four patients with PCH were 28 female (43.8%) and 36 (56.3%) male. The patients revealed homozygous mutation in 89.1%, consanguinity in 79.7%, pregnancy at term in 85.2%, microcephaly in 91.3%, psychomotor retardation in 98.4%, abnormal neurological findings in 100%, seizure in 63.8%, normal biochemistry and metabolic investigations in 92.2%, and dysmorphic findings in 51.2%. The missense mutation was found to be the most common variant type in all patients with PCH. It was detected as CLP1 (n = 17) was the most common PCH related gene. The homozygous missense variant c.419G > A (p.Arg140His) was identified in all patients with CLP1. Moreover, all patients showed the same homozygous missense variant c.919G > T (p.A307S) in TSEN54 group (n = 6). In Turkey, CLP1 was identified as the most common causative gene with the identical variant c.419G > A; p.Arg140His. The current study supports that genotype data on PCH leads to phenotypic variability over a wide phenotypic spectrum.

Birth Asphyxia among Neonates Admitted to the Neonatal Intensive Care Unit of a Tertiary Care Hospital.

Birth asphyxia causes significant morbidity and mortality among neonates, especially in low-income and middle-income countries like Nepal. However, there is a paucity of data regarding its burden. This study aimed to find the prevalence of birth asphyxia among neonates admitted to the neonatal intensive care unit of a tertiary care hospital. This descriptive cross-sectional study was conducted among neonates at a tertiary care hospital between 15 January 2022 to 14 January 2023 after obtaining ethical approval from the Institutional Review Committee. Neonates with gestational age ≥35 weeks were included and those with major congenital anomalies were excluded. A convenience sampling method was used. A point estimate was calculated at a 95% Confidence Interval. Among 902 neonates, 120 (13.30%) (11.08-15.52, 95% Confidence Interval) had birth asphyxia. A total of 108 (90%) were outborn, and 84 (70%) were males. HIE stage-I, II and III were seen in 47 (39.17%), 64 (53.33%) and 9 (7.50%) of the asphyxiated neonates respectively. Poor suck 92 (76.67%), seizures 73 (60.83%) and lethargy 70 (58.33%) were common abnormal neurological findings. Death occurred in 15 (12.50%) neonates in the hospital. The prevalence of birth asphyxia was found to be similar to other studies done in similar settings. The high burden underscores an urgent need to implement better perinatal care and delivery room management practices. hypoxic-ischemic encephalopathy; neonates; prevalence.

Cauda equina syndrome in a patient with human immunodeficiency virus and secondary central nervous system lymphoma: a case report

BackgroundSecondary central nervous system lymphoma (SCNSL) is a known complication of immunocompromised patients with most cases involving the brain parenchyma. Reports of cauda equina syndrome (CES) caused by SCNSL are exceedingly scarce as involvement of this anatomical region is extremely uncommon.Case presentationWe report a case of a 46-years-old, African, female patient with human immunodeficiency virus (HIV) who developed CES in the context of SCNSL. There were no blasts present in the peripheral blood smear. We provide a review of the literature, discussion of the clinical evolution of this patient and the radiological/histopathological findings. The patient ultimately responded well to induction chemotherapy and high dose methotrexate.ConclusionThis case report demonstrates that CES, while a rare occurrence in this clinical context, should be considered in at-risk patients especially those presenting with abnormal neurological findings. Prompt recognition may prevent permanent neurological injury and obviate the need for more invasive therapeutic interventions.

Abnormal Neurologic Findings in Patients With Sickle Cell Disease Without a History of Major Neurologic Events.

Patients with sickle cell disease (SCD) are prone to symptomatic neurologic complications. Previous studies reported accrual of neural injury starting at early age, even without having symptomatic neurologic events. The aim of this study was to assess the prevalence and risk factors of abnormal neurologic findings in patients with SCD with no history of major symptomatic neurologic events. Our study extracted patients diagnosed with SCD from the Cooperative Study of Sickle Cell Disease. Patients who underwent a neurologic evaluation were included in our analysis. Patients with previous documented major symptomatic neurologic events were excluded. We compared patients with SCD with abnormal neurologic findings with those without in terms of clinical and laboratory parameters using multivariate binary logistic regression. A total of 3,573 patients with SCD were included (median age = 11 [IQR = 19] years, male = 1719 [48.1%]). 519 (14.5%) patients had at least one abnormal neurologic finding. The most common findings in descending order were abnormal reflexes, gait abnormalities, cerebellar dysfunction, language deficits, nystagmus, abnormal muscle tone and strength, Romberg sign, Horner syndrome, and intellectual impairment. History of eye disease (odds ratio [OR] = 2.76, 95% confidence interval [CI] = 1.63-4.68) and history of osteomyelitis (OR = 2.55, 95% CI 1.34-4.84) were the strongest predictors of abnormal neurologic findings, followed by smoking (OR = 1.59, 95% CI 1.08-2.33), aseptic necrosis (OR = 1.57, 95% CI 1.06-2.33), hand-foot syndrome (OR = 1.48, 95% CI 1.04-2.12), and male sex (OR = 1.42, 95% CI 1.01-2.02). Neurologic deficits are relatively common in patients with SCD, even without documented major neurologic insults. They range from peripheral and ophthalmic deficits to central and cognitive disabilities. Patients with SCD should have early regular neurologic evaluations and risk factor modification, particularly actively promoting smoking cessation.

Epilepsy Frequency and Risk Factors Three Years After Neonatal Seizures

BackgroundNeonatal seizures, one of the main risk factors for the development of epilepsy, remain a clinical concern. In children with neonatal seizures, early recognition of risk factors is important for the early diagnosis and appropriate treatment of epilepsy and for improving prognosis. In this study, we aimed to determine the frequency of and the risk factors for the development of epilepsy in patients with neonatal seizures. MethodsThe hospital files of 228 children who experienced seizures in the neonatal period were reviewed. The frequency of epilepsy and risk factors for the development of epilepsy were determined at age 36 months. ResultsEpilepsy was diagnosed in 40.8% of the cases. Univariate analysis revealed family history of epilepsy, parental consanguinity, abnormal neurological examination findings, microcephaly, unresponsiveness to antiepileptic drugs or antiseizure medication, use of more than one antiepileptic drugs to antiseizure medication at discharge, status epilepticus, electroencephalography abnormalities, abnormal neuroimaging findings, invasive ventilation requirement, myoclonic seizures, central nervous system malformation, and congenital metabolic disease as risk factors for the development of epilepsy. Of these, a family history of epilepsy, abnormal neurological examination findings at discharge, and use of at least two antiepileptic drugs to antiseizure medication at discharge were found as independent risk factors in multivariate analysis. ConclusionsNeonatal seizures appear to be associated with epilepsy in more than one-third of the patients. Of the newborns with seizures, those with a family history of epilepsy, abnormal neurological examination findings at discharge, and those using at least two antiepileptic drugs to antiseizure medication at discharge should be monitored more carefully for the development of epilepsy.

On-Field and Pitch-Side (Sideline) Assessment of Sports Concussion in Collision Sports: An Expert Consensus Statement Using the Modified Delphi Technique

To perform a Delphi consensus for on-field and pitch-side assessment of sports-related concussion (SRC). Open-ended questions in rounds 1 and 2 were answered. The results of the first 2 rounds were used to develop a Likert-style questionnaire for round 3. If agreement at round 3 was ≤80% for an item, if panel members were outside consensus, or there were >30% neither agree/disagree responses, the results were carried forward into round 4. The level of agreement and consensus was defined as 90%. Loss of consciousness (LOC) or suspected LOC, motor incoordination/ataxia, balance disturbance, confusion/disorientation, memory disturbance/amnesia, blurred vision/light sensitivity, irritability, slurred speech, slow reaction time, lying motionless, dizziness, headaches/pressure in the head, falling to the ground with no protective action, slow to get up after a hit, dazed look, and posturing/seizures were clinical signs of SRC and indicate removal from play. Video assessment is helpful but should not replace clinical judgment. LOC/unresponsiveness, signs of cervical spine injury, suspicion of other fractures (skull/maxillo-facial), seizures, Glasgow Coma Scale score <14 and abnormal neurologic examination findings are indications for hospitalization. Return to play should only be considered when no clinical signs of SRC are present. Every suspected concussion should be referred to an experienced physician. Consensus was achieved for 85% of the clinical signs indicating concussion. On-field and pitch-side assessment should include the observation of the mechanism, a clinical examination, and cervical spine assessment. Of the 19 signs and red flags requiring removal from play, consensus was reached for 74%. Normal clinical examination and HIA with no signs of concussion allow return to play. Video assessment should be mandatory for professional games but should not replace clinical decision-making. Sports Concussion Assessment Tool, Glasgow Coma Scale, vestibular/ocular motor screening, Head Injury Assessment Criteria 1, and Maddocks questions are useful tools. Guidelines are helpful for non-health professionals. Level V, expert opinion.

Adverse Effects of Topiramate in Neonate with Moderate to Severe Perinatal Asphyxia: A Randomized Controlled Trial

Introduction: A harmful pregnancy condition that harms both the mother and the fetus is perinatal asphyxia. It frequently happens as a result of challenges during labour, including protracted or challenging delivery, concerns with the umbilical cord, placental abnormalities, or maternal health conditions. Topiramate, an anticonvulsant, works through a variety of different methods. Topiramate looks to be effective as a neuroprotective agent as well as an anti-seizure medication in animal models of newborn brain injury. Angiogenesis, neurogenesis, and neuronal anti-apoptotic pathways are all stimulated and regulated by topiramate. In light of this, this observational study was conducted to ascertain Topiramate's negative consequences in kids with mild to moderate neonatal hypoxia. Methods: This observational case-control study was carried out in the Neonatal ward and ICU of Dhaka Shishu Hospital from April 2015 to March 2016. A total of 64 neonates were enrolled in this study and were assigned Group A -the interventional group (n=32) received topiramate and standard treatment protocol, and Group B or the control group (n=32) received only standard treatment protocol. The data were analyzed according to standard procedure. Results: Among the study neonates, based on sex in case and control groups, respectively, seventeen (17,53%) and twenty-one (21,66%) neonates were male, and fifteen (15,47%) and eleven (11,44%) neonates were female. Statistically, the sex distribution between groups was not significant (p=0.44). USG finding of the neonates after treatment was normal in 12 (48%) and 13(41%), and abnormal in 20(32%) and 19 (59%) neonates in the control and case groups, respectively. Out of 27 neonates in the control group, 11 (41%) were neurologically normal, and 16 (59%) had abnormal neurological findings. Out of 29 neonates in the case group, 24 (73%) were neurologically normal, and 5(17%) showed abnormal neurological findings. Statistically, significant variation ..

Occult fractures detected on radiographs in young children with a concern for abusive head trauma.

To determine the incidence of children < 2 years old with suspected abusive head trauma, to evaluate usage of dedicated skeletal radiographs and the incidence of clinically occult fractures on dedicated skeletal radiographs. This is a retrospective single centre study of children < 2 years old with traumatic brain injury, referred to the University Hospital's Social Services Department between December 31, 2012 and December 31, 2020. Clinical and demographic data was retrieved from medical notes and imaging was reviewed by paediatric radiologists. 26 children (17 males), 2 weeks to 21 months of age (median age 3 months) were included. Eleven children (42%) had traumatic history, fourteen children (54%) had one or more bruises, eighteen children (69%) had abnormal neurological findings. 16 children (62%) had dedicated skeletal radiographs, 7 children (27%) had radiographs of part of the skeleton and 3 children (11%) had no skeletal radiographs. 5 out of 16 children (31%) with dedicated skeletal radiographs had a clinically occult fracture. 15 (83%) of clinically occult fractures had high specificity for abuse. The incidence of suspected abusive head trauma in children < 2 years old is low. Clinically occult fractures were detected in one third of children with dedicated skeletal radiographs. The majority of these fractures have high specificity for abuse. Dedicated skeletal imaging is not performed in more than one third of the children and hence fractures may be missed. Efforts should be taken to increase awareness of child abuse imaging protocols.

Neurologic Consultations and Headache during Pregnancy and in Puerperium: A Retrospective Chart Review.

Headache is a common symptom during pregnancy and in puerperium that requires careful consideration, as it may be caused by a life-threatening condition. Headaches in pregnant women and women in puerperium are classified as primary or secondary; acute, severe and newly diagnosed headaches should prompt further investigation. We aimed to further characterise the demographic features, symptoms, examination findings, and neuroimaging results of cases of headache during pregnancy and in puerperium. All pregnant women or women in postpartum conditions who attended neurological consultations at the emergency department of the clinic for Gynaecology, Obstetrics and Reproductive Medicine of Saarland University/Germany between 2001/2015 and 2012/2019 were enrolled in this retrospective chart review. Data collected from the charts included demographic/pregnancy characteristics, clinical features and imaging findings. Descriptive statistics as well as binary logistic regression were performed. More than 50% of 97 patients had abnormal findings in their neurological examination. Magnetic resonance imaging findings were pathological for almost 20% of patients-indicating conditions such as cerebral venous thrombosis, reversible posterior leukoencephalopathy, brain tumour and intracranial bleeding. The odds of abnormal neuroimaging results were 2.2-times greater among women with abnormal neurological examination findings than among those with normal examination results. In cases of headache during pregnancy and in puerperium, neuroimaging should be indicated early on. Further research is needed to determine which conditions indicate a need for immediate neuroimaging.

Sensitization of Hoffmann’s sign in response to a reverse Lhermitte’s sign: a case report

ABSTRACT Background Neurologic clustering of findings is recommended with Cervical Spondylotic Myelopathy (CSM). Hoffmann’s Sign and Reverse Lhermitte’s Sign have been associated with CSM, which, however, have not been discussed as the only objective findings that may cause clinical uncertainty. Case Description This case report describes how sensitizing Hoffmann’s Sign following a Reverse Lhermitte’s Sign guided reasoning, with a 66-year-old male presenting with a right lumbar radiculopathy diagnosis. Local lumbar symptoms and impairments were identified, however, a Reverse Lhermitte’s Sign with cervical extension was the only finding that reproduced right lower extremity (LE) pain. Hoffmann’s Sign, the only abnormal neurologic finding, became exaggerated when performed in cervical extension. Concern of an early presenting CSM accounting for right LE pain was considered. A neurosurgical consultation was initiated with concurrent guideline-based lumbar spine treatment and continued monitoring of neurologic status. Outcomes Seven weeks after evaluation, sudden worsening of right LE symptoms, hand numbness, ataxia, and grip weakness occurred. Cervical magnetic resonance imaging demonstrated C3-6 cord compression. A multi-level cervical decompression surgery was performed. Discussion Using a sensitized Hoffmann’s Sign-in response to a Reverse Lhermitte’s Sign aided differential diagnosis of an early presenting CSM with reports of LE pain. The diagnostic utility of a sensitized Hoffmann’s Sign is unknown.

Patterns of MRI Findings in Patients with Chronic Headache: A Retrospective Study from a Private Diagnostic Center in Addis Ababa, Ethiopia.

Headache is one of the most common complaints that lead the patient to seek medical advice however only a few patients with recurrent headaches have a secondary cause like intracranial mass. The appropriate utilization of neuroimaging is important to rule-out secondary cause of headache in resource-limited regions. The objective of this study is to describe the patterns of MRI findings in the evaluation of patients with chronic headache and to determine the clinical variables helpful in identifying patients with intracranial lesions. This cross sectional study was conducted among 590 selected patients who underwent an MRI scan of the head from September 2016 to January 2018 at Wudassie Diagnostic center in Addis Ababa, Ethiopia. Siemens Magnetom 0.35T MRI was used. Out of 590 patients, 372 (63.1%) were females and 218 (36.9%) were males; 300 (50.8%) patients with the mean age of 38.6 ± 0.5 years and a median of 37 ± 16.7years have normal brain MRI and 290(49.2%) have abnormal brain MRI reports. The abnormal findings further divided into non-significant findings were 166(28%) that did not alter patient management and clinically significant findings were 124 (21%) which included by decreasing order of frequency tumors, infection, hydrocephalus, hemorrhage, and vascular abnormalities. It was 1.3 times higher rate of positive brain MR findings in patients who had headaches plus abnormal neurologic findings as compared to patients without neurologic abnormality (P-value = 0.01). There is a high rate of significant abnormal MRI findings in this study as compared to studies from developed nations.

Low-back pain in adolescents with an osteopathic component

Low-back pain (LBP) is a common symptom presenting in adolescents. Most back pain in adolescents is benign and musculoskeletal in nature, due to trauma or congenital anomalies. Other less common causes include infection, inflammatory conditions or neoplasm. A comprehensive history and physical focusing on posture, muscle tenderness, range of motion, muscle strength and neurological function is essential in understanding the cause of low-back pain. Identification of risk factors for low-back pain will help the clinician in managing their patient. Treatment includes rest, avoiding activities that cause pain, physical therapy, osteopathic manipulative treatment, limited use of non-steroidal anti-inflammatory drugs and family and patient education. Assessing for warning signs or red flags of serious causes of LBP is a fundamental part of the clinical assessment. Pain that awakens from sleep, pain lasting longer than 4 weeks, sudden onset pain, systemic findings such as fever or weight loss and abnormal neurological findings should warrant immediate evaluation as these may suggest serious infectious conditions, malignancy or fracture. This article presents a comprehensive review of the epidemiology, relevant anatomy, biomechanics, causes and major risk factors for adolescent low-back pain. A diagnostic algorithm utilizing a step-by-step approach is also introduced to aid the clinician in management of the patient. Finally, the article presents guidelines for management of the adolescent with low-back pain including conservative, pharmacologic, as well as the osteopathic approach to treatment. Evidence-based recommendations on osteopathic approach to treatment has been reviewed from meta-analysis data and randomized controlled trials.

Congenital Rubella syndrome cases (based on WHO criteria) one decade after Measle and Rubella vaccination campaign in Tehran; Iran.

Background: Active CRS surveillance is recommended strongly even in country with full rubella vaccination. Objective: Searching the CRS based on WHO criteria one decade after MR vaccination campaign (2003) Methods: a prospective case control study carried out in a third referral educational hospital (Rasoul Akram hospital) in Tehran, IRAN during five years (2013 -2018). From 89 CRS suspected infants (according to WHO criteria); serum samples were tested for rubella-specific IgG and IgM by ELISA method. Selected samples (positive Rubella IgM) were tested for rubella RNA by reverse transcriptase–polymerase chain reaction (RT–PCR). Findings: “Confirmed CRS” based on positive IgM was found in 5.6% (5/89) all were &lt; 4 months old. Positive RT–PCR detected in 1.2 % (1/89) of “CRS suspected” infants.Except a good correlation between abnormal neurologic findings and positive IgM in “Confirmed CRS “cases, other clinical findings were not related to serologic tests. The “Compatible CRS” cases in the 31 patients who had primary negative IgM serology and did not have sufficient laboratory evidence to confirm CRS, but clinical symptoms favoured CRS. Conclusion: Despite MR vaccination in Iran, after one decade “confirmed CRS” and “compatible CRS” were diagnosed in 5 and 31 from 89 CRS suspected cases. The incidence of “confirmed CRS” in every 100 CRS suspected infants (after campaign) is 5.6 %; and 31 CRS Compatible cases are so important. Without active CRS surveillance; mild infection such as IUGR, hearing loss,heart abnormalities, impaired vision, and mental retardation even in developed country might be missed.Fetal infection is persistent which impose additional costs on the country..Another mass vaccination in women and girls is needed. Also, the antirubella IgG testing before pregnancy in women who were not vaccinated; vaccination of women before marriage /preganacy should be obligatory in order to prevent the CRS.

Prenatally diagnosed isolated perimembranous ventricular septal defect: Genetic and clinical implications.

ObjectiveTo evaluate the incidence of chromosomal aberrations and the clinical outcomes following the prenatal diagnosis of isolated perimembranous ventricular septal defect (pVSD).MethodsThis retrospective study was composed of a cohort of pregnant women whose fetuses were diagnosed with isolated pVSD. Complete examinations of the fetal heart were performed, as well as a postnatal validation echocardiography follow‐up at 1 year of age. The collected data included: spontaneous closure of the pVSD, need for intervention, chromosomal aberrations and postnatal outcome.ResultsFifty‐five pregnant women were included in the study. 34/55 (61.8%) of the fetuses underwent prenatal genetic workup which revealed no abnormal results. No dysmorphic features or abnormal neurological findings were detected postnatally in those who declined a prenatal genetic workup during the follow‐up period of 2 years. In 25/55 of the cases (45.4%), the ventricular septal defects (VSD) closed spontaneously in utero, whereas in 17 cases of this group (30.9%) the VSD closed during the first year of life. None of the large 3 VSDs cases (>3 mm), closed spontaneously.ConclusionPrenatally isolated perimembranous VSD has a favorable clinical outcome when classified as small‐to‐moderate size, children in our cohort born with such findings had no macroscopic chromosomal abnormalities.

Nivolumab-related myasthenia gravis with myositis requiring prolonged mechanical ventilation: a case report

BackgroundNivolumab is an immune checkpoint inhibitor that blocks inhibitors of T-cell activation and blunts antitumor immunity and is used in the treatment of various cancers. However, immune checkpoint inhibitors have immune-related adverse effects on various organs due to promoting T-cell activity against host tissues by blocking inhibition of T-cell function. Although immune-related adverse effects including hepatitis, colitis, pneumonitis, dermatitis, nephritis, endocrinopathies, and hypophysitis are well recognized with established treatment guidelines, neuromuscular immune-related adverse effects are rare phenomena.Case presentationA 55-year-old Asian (Japanese) woman was diagnosed with nivolumab-related myasthenia gravis with myositis and myocarditis. She had a past history of thymectomy for large thymoma with a high anti-acetylcholine receptor antibody level without any symptoms. Nivolumab was administered for the treatment of malignant melanoma. Creatine kinase levels began to rise 2 weeks after the administration, and abnormal neurological findings appeared 3 weeks after the administration. Ventricular arrhythmia, wide QRS complex, and dyssynchrony of the left ventricle also appeared. Intravenous immunoglobulin and corticosteroids were administered, and plasma exchange was performed. The patient required intensive care and prolonged mechanical ventilation with tracheostomy owing to weakness of the diaphragm; she was eventually weaned from the ventilator and discharged. Diaphragm ultrasound was used for the decision-making of the weaning strategy and evaluation of the diaphragmatic function.ConclusionsNivolumab-induced severe myasthenia gravis with myositis and myocarditis required intensive care and prolonged mechanical ventilation. Although immune checkpoint inhibitor-related myasthenia gravis is a rare adverse event, appropriate and prompt treatment is required because of its severity and rapid progression. Diaphragm ultrasound was useful not only in diagnosing diaphragm dysfunction and deciding the strategy for weaning from mechanical ventilation but also in evaluating the recovery of the diaphragmatic function.

Neurological manifestations and etiological risk factors in patients hospitalized with COVID-19 in Turkey.

Coronavirus disease 2019 (COVID-19) can affect the neurological as well as the respiratory system. Neurological manifestations may involve the central or peripheral nervous systems, or musculoskeletal system. Findings can range from mild presentations, such as headache and anosmia, to severe complications, such as stroke and seizure. To evaluate the neurological findings and to determine etiological risk factors for mortality in patients hospitalized for COVID-19. Medical records of patients with COVID-19 who were hospitalized and sought neurological consultation between March 2020 and March 2021 at a reference pandemic hospital in Turkey were reviewed retrospectively in a cross-sectional study design. We included data from 150 (94 male) patients. Their mean age ± standard deviation was 68.56 ± 16.02 (range 21-97) years. The patients were categorized into 2 groups according to any acute neurological event or progression of neurological disease. Ischemic cerebrovascular events, seizures, and encephalopathy were the most common acute neurological events, while deterioration in consciousness, epileptic seizures, and Parkinson disease were observed in those with progression of neurological disease. Abnormal neurological findings were found at a mean of 7.8 ± 9.7 days following COVID-19 diagnosis and 50 (a third of) patients died. A logistic regression model found that advanced age, increased Modified Charlson Comorbidity Index (MCCI) score, and prolonged duration of hospitalization were factors significantly associated with increased mortality; however, sex and day of abnormal neurological findings after COVID-19 diagnosis were not. Common conditions accompanying neurological events were hypertension, coronary artery disease-heart failure, and diabetes mellitus. COVID-19 may present with neurological symptoms in our Turkish patients and comorbidities are often present.

Postneonatal Epilepsy and Psychomotor Developmental Retardation Risk Factors in Term Neonatal Convulsions Without Hypoxic Ischemic Encephalopathy

Objective: Neonatal convulsions may be an early sign of brain injury and the presence of convulsions in the neonatal period has been associated with long-term sequelaes such as mental retardation, postnatal epilepsy and death. We aimed to determine associations of etiological factors with neurodevelopment and postneonatal epilepsy and evaluate the risk factors in newborns with neonatal convulsions that were not related to hypoxic-ischemic encephalopathy. Material and Methods: This study included full-term infants who were born between January 2010 and December 2014 and had neonatal convulsion history, had no history of hypoxic-ischemic encephalopathy and were followed for at least 1 year at our neurology clinic. Results: Forty-nine patients were included to the study. Among the identified etiologies on first clinical visit, hypoglycemia was the most common cause which was presented in 11 (40.74%; 11/27 patients) patients. During follow-up, 22.4% (n=11) of patients developed postneonatal epilepsy. In 4 of 7 patients with abnormal Bayley II test results, epilepsy developed in the follow-up. The risk for development of postneonatal epilepsy was significantly associated with abnormal neurological findings, such as cerebral palsy or significant delays in developmental stages; being not benefited from acute treatment and follow-up abnormal EEG findings of the patients. Conclusion: Hypoglycemia should be primarily investigated and treated in term neonatal seizures without hypoxia. Abnormal neurological findings, being not benefited from the acute treatment and follow-up EEG findings were associated with developing epilepsy. In the literature, most of the studies were limited due to short follow-up periods. More information about prognostic factors in neonatal convulsions and the occurrence of postneonatal epilepsy is needed.

Rapidly progressive brain atrophy in septic ICU patients: a retrospective descriptive study using semiautomatic CT volumetry

BackgroundSepsis is often associated with multiple organ failure; however, changes in brain volume with sepsis are not well understood. We assessed brain atrophy in the acute phase of sepsis using brain computed tomography (CT) scans, and their findings’ relationship to risk factors and outcomes.MethodsPatients with sepsis admitted to an intensive care unit (ICU) and who underwent at least two head CT scans during hospitalization were included (n = 48). The first brain CT scan was routinely performed on admission, and the second and further brain CT scans were obtained whenever prolonged disturbance of consciousness or abnormal neurological findings were observed. Brain volume was estimated using an automatic segmentation method and any changes in brain volume between the two scans were recorded. Patients with a brain volume change < 0% from the first CT scan to the second CT scan were defined as the “brain atrophy group (n = 42)”, and those with ≥ 0% were defined as the “no brain atrophy group (n = 6).” Use and duration of mechanical ventilation, length of ICU stay, length of hospital stay, and mortality were compared between the groups.ResultsAnalysis of all 42 cases in the brain atrophy group showed a significant decrease in brain volume (first CT scan: 1.041 ± 0.123 L vs. second CT scan: 1.002 ± 0.121 L, t (41) = 9.436, p < 0.001). The mean percentage change in brain volume between CT scans in the brain atrophy group was –3.7% over a median of 31 days, which is equivalent to a brain volume of 38.5 cm3. The proportion of cases on mechanical ventilation (95.2% vs. 66.7%; p = 0.02) and median time on mechanical ventilation (28 [IQR 15–57] days vs. 15 [IQR 0–25] days, p = 0.04) were significantly higher in the brain atrophy group than in the no brain atrophy group.ConclusionsMany ICU patients with severe sepsis who developed prolonged mental status changes and neurological sequelae showed signs of brain atrophy. Patients with rapidly progressive brain atrophy were more likely to have required mechanical ventilation.

Clinical profile and outcome of children with acute bacterial meningitis in a tertiary care centre in eastern Nepal

Background: Bacterial meningitis is a severe infection of the central nervous system with varied clinical presentations. It is associated with substantial mortality and morbidity. Objectives: The objective of this study was to assess the clinical profile, including the clinical features, laboratory and radiological parameters, clinical course, treatment, response to treatment, complications, and outcome of children at discharge. Methods: A prospective observational study was conducted among 52 inpatient children of acute bacterial meningitis aged one month to 14 years over a period of six months. The patients were enrolled during admission and followed up daily till discharge. Socio-demographic, clinical, and diagnostic details and outcomes were recorded and analysed using statistical package for social sciences version 20. Results: The median age of the patients was two years with male to female ratio of 2:1. Fever (45, 87%), vomiting (37, 71%), seizure (33, 64%) and headache (22, 46%) were the most common symptoms. The cerebrospinal fluid culture was positive in three (6%) cases. Complications were seen in 20 (39%) patients including four (7.7%) deaths. Patients with prolonged fever, malnutrition, loss of consciousness, ear discharge, presence of meningeal signs, abnormal pupil, high cerebrospinal fluid protein, positive cerebrospinal fluid, and blood culture, low blood pH, and hyperlactataemia were significantly associated with complications (p &lt;0.05). Conclusion: Factors like malnutrition, longer duration of fever, and abnormal neurological and laboratory findings were associated with higher rates of complications.
