Background: Dengue is a common endemic infection in India. Neurological complications involving various parts of the neuro-axis have been reported. We report neurological complications amongst dengue patients admitted to a tertiary hospital in Western India. Materials and Methods: Patients admitted in a tertiary hospital in Western India with dengue infection and having neurological symptoms were included in this study. Their history, physical examination, laboratory investigations and imaging studies were obtained from the inpatient records and analysed. Results: Between January 2014 to December 2019, a total of 5821 patients were diagnosed with dengue. Of these, 154 (2.64%) had neurological manifestations. Encephalopathy in a setting of multisystem involvement was seen in 31.2% patients, encephalitis with focal features, abnormal imaging and/or abnormal cerebrospinal fluid (CSF) examination was seen in 15.6%, syncope in 27.3% and acute symptomatic seizure in 11.0%. Less common presentations were intracranial haemorrhage (4.5%), Guillain-Barre syndrome (GBS) (3.2%), optic neuritis (1.9%), myositis (1.3%), hypokalemic paralysis (1.3%), ischemic stroke (0.6%), posterior reversible encephalopathy syndrome (PRES) (0.6%), myoclonus (0.6%) and brachial plexopathy (0.6%). Conclusions: In this study of patients admitted with dengue, neurological complications due to dengue were seen in 2.64%. Encephalopathy, encephalitis and syncope were the commonest manifestations, followed by acute symptomatic seizures, intracranial haemorrhage and GBS. The entire neuroaxis can be involved in dengue infection. To the best of our knowledge, this is the largest reported study of neurological complications of dengue.
Background: There has been an increase an alarming rise in invasive mycoses during COVID-19 pandemic, especially during the second wave. Aims: Compare the incidence of invasive mycoses in the last three years and study the risk factors, manifestations and outcomes of mycoses in the COVID era. Methodology: Multicentric study was conducted across 21 centres in a state of western India over 12-months. The clinico-radiological, laboratory and microbiological features, treatment and outcomes of patients were studied. We also analysed yearly incidence of rhino-orbito-cerebral mycosis. Results: There was more than five-times rise in the incidence of invasive mycoses compared to previous two-years. Of the 122 patients analysed, mucor, aspergillus and dual infection were seen in 86.9%, 4.1%, and 7.4% respectively. Fifty-nine percent had simultaneous mycosis and COVID-19 while rest had sequential infection. Common presenting features were headache (91%), facial pain (78.7%), diplopia (66.4%) and vison loss (56.6%). Rhino-orbito-sinusitis was present in 96.7%, meningitis in 6.6%, intracranial mass lesions in 15.6% and strokes in 14.8%. A total of 91.8% patients were diabetic, while 90.2% were treated with steroids during COVID-19 treatment. Mortality was 34.4%. Conclusion: Invasive fungal infections having high mortality and morbidity have increased burden on already overburdened healthcare system. Past illnesses, COVID-19 itself and its treatment and environmental factors seem responsible for the rise of fungal infection. Awareness and preventive strategies are the need of hours and larger studies are needed for better understanding of this deadly disease.
Background: Discovery of serum myelin oligodendrocyte glycoprotein (MOG) antibody testing in demyelination segregated MOG-IgG disease from AQ-4-IgG positive NMOSD. Aims: To study clinico-radiological manifestations, pattern of laboratory and electrophysiological investigations and response to treatment through follow up in MOG-IgG positive patients. Method: Retrospective data of MOG-IgG positive patients was collected. Demographics, clinical manifestations at onset and at follow up and relapses, anti AQ-4-IgG status, imaging and all investigations were performed, treatment of relapses and further immunomodulatory therapy were captured. Results: In our 30 patients, F: M ratio was 2.75:1 and adult: child ratio 4:1. Relapses at presentation were optic neuritis {ON}(60%), longitudinally extensive transverse myelitis {LETM}(20%), acute disseminated encephalomyelitis {ADEM}(13.4%), simultaneous ON with myelitis (3.3%) and diencephalic Syndrome (3.3%). Salient MRI features were ADEM-like lesions, middle cerebellar peduncle fluffy infiltrates, thalamic and pontine lesions and longitudinally extensive ON {LEON} as well as non-LEON. Totally, 50% patients had a relapsing course. Plasma exchange and intravenous immunoglobulin worked in patients who showed a poor response to intravenous methylprednisolone. Prednisolone, Azathioprine, Mycophenolate and Rituximab were effective attack preventing agents. Conclusions: MOG-IgG related manifestations in our cohort were monophasic/recurrent/simultaneous ON, myelitis, recurrent ADEM, brainstem encephalitis and diencephalic Syndrome. MRI features suggestive of MOG-IgG disease were confluent ADEM-like lesions, middle cerebellar peduncle fluffy lesions, LETM, LEON and non-LEON. Where indicated, patients need to go on immunomodulation as it has a relapsing course and can accumulate significant disability. Because of its unique manifestations, it needs to be considered as a distinct entity. To the best of our knowledge, this is the largest series of MOG-IgG disease reported from India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
