Dermato-neuro syndrome is a potentially fatal neurological complication of scleromyxedema consisting of fever, seizures, and coma. This is an overlooked scleromyxedema case of a 62-year-old female patient from 2-years ago. She was admitted to our ICU because of high fever, colloid speech, muscle ache, and nausea. Molecular methods in the cerebrospinal fluid for neurotropic viruses ruled out acute infectious encephalitis. Her thyroid hormones were within normal values while the serum protein electrophoresis confirmed the monoclonal gammopathy of immunoglobulin G lambda (IgG(λ)), known for the last 2 years. The subsequent bone-marrow biopsy excluded the development of multiple myeloma. The patient fulfilled fundamental diagnostic criteria of scleromyxedema (monoclonal gammopathy, normal thyroid function and the appearance of marked sclerosis and induration of the skin papules on the face, neck, extremities, and skin creases) presenting as dermato-neuro syndrome, which was histologically confirmed. She demonstrated a remarkable improvement after intravenous immunoglobulin treatment during the first 24 hours. Mimics of non-infectious acute encephalitis should include the clinical diagnosis of scleromyxedema, especially when patients present in the emergency department with acute fever, coma, and skin lesions of diffuse sclerodermoid and papular type., (Copyright © 2020 Southern Society for Clinical Investigation.

Febrile infection-related epilepsy syndrome (FIRES) is a severe epilepsy disorder that affects previously healthy children. It carries high likelihood of unfavourable outcome and putative aetiology relates to an auto-inflammatory process. Standard antiepileptic drug therapies including intravenous anaesthetic agents are largely ineffective in controlling status epilepticus in FIRES. Deep brain stimulation of the centromedian thalamic nuclei (CMN-DBS) has been previously used in refractory status epilepticus in only a few cases. The use of Anakinra (a recombinant version of the human interleukin-1 receptor antagonist) has been reported in one case with FIRES with good outcome. Here we describe two male paediatric patients with FIRES unresponsive to multiple anti-epileptic drugs, first-line immune modulation, ketogenic diet and cannabidiol. They both received Anakinra and underwent CMN-DBS. The primary aim for CMN-DBS therapy was to reduce generalized seizures. CMN-DBS abolished generalized seizures in both cases and Anakinra had a positive effect in one. This patient had a favourable outcome whereas the other did not. These are the first reported cases of FIRES where CMN-DBS has been used., (Crown Copyright © 2019. Published by Elsevier Ltd. All rights reserved.)

Aim: To determine the use of high b value diffusion-weighted imaging (DWI) in the diagnosis and assessment of acute febrile encephalopathy/encephalitis in childhood., Subjects and Methods: We enrolled 22 children, for whom we examined DWI with b=1000s/mm 2 , DWI with b=3000s/mm 2 , and apparent diffusion coefficient (ADC) map with b=1000 during the acute phase of febrile encephalopathy/encephalitis. Clinical diagnoses included acute encephalopathy with biphasic seizures and late reduced diffusion (AESD; n=6), clinically mild encephalopathy/encephalitis with a reversible splenial lesion (MERS; n=6), and herpes simplex virus encephalitis (HSE; n=3), unclassified acute encephalopathy/acute encephalitis (n=2); acute encephalitis with refractory, repetitive partial seizures (AERRPS; n=1); other encephalopathy (n=1); infarction (n=1); head injury (n=1); or mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (n=1). The diagnostic quality of brain lesions was compared between b=1000 and b=3000 DWI images by visual inspection. In addition, we attempted a quantitative assessment using apparent diffusion coefficient (ADC) value and an index of signal intensity (SI) ratio, defined as the mean SI at the affected lesion divided by the mean SI at the pons., Results: High intensity lesions were either visible only on b=3000 DWI (n=5; 2 AESD, 1 MERS, 1 HSE, and 1 unclassifiable encephalopathy) or more effectively identified on b=3000 DWI than on b=1000 DWI (n=17). The outcome of the former five subjects was favorable, without motor or intellectual sequelae. The mean SI ratio of b=3000 was significantly greater than that of b=1000 in AESD and MERS subgroups as well as in all 22 subjects. Mean ADC values were lower in the AESD and MERS than that in the HSE subgroups., Conclusion: We concluded that b=3000 DWI was superior to b=1000 DWI in detecting abnormal lesions in acute encephalopathy/encephalitis during childhood., (Copyright © 2017 The Japanese Society of Child Neurology.

Context: Acute encephalitis syndrome (AES) is a serious public health problem, caused mainly by viruses. However, the profile of viruses causing AES in Rajasthan is not well characterised., Aims: The present study was undertaken to identify the viruses causing AES and develop diagnostic algorithm so as to help in improved diagnosis, treatment, prevention and control., Settings and Design: The present study is a hospital-based descriptive, observational study. Samples were processed at Grade-1 DHR/ICMR Viral Research and Diagnostic Laboratory at SMS, Jaipur., Subjects and Methods: Cerebrospinal fluid (CSF) samples were processed for IgM antibody detection by enzyme-linked immunosorbent assay (ELISA) for mumps virus (MPV), measles virus (MV), Rubella virus (RV), Japanese encephalitis virus (JEV), West Nile virus (WNV) and Dengue virus using commercial kits. Nucleic acid was extracted from CSF using automated extraction system. Real-time polymerase chain reaction was done using specific primers and probes for Herpes simplex virus (HSV), Varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV) and enterovirus (EV)., Statistical Analysis Used: Statistical analysis was done using ANOVA., Results: Among 3088 patients, 702 (22.7%) patients were positive for one or more viruses. HSV (261;8.45%) was the most common followed by EBV (173;5.6%), VZV (97;3.1%), CMV (68;2.2%), EV (32;1.03%), MPV (27;0.9%), DV (28;0.9%), MV (19;0.6%) and RV (6;0.2%)., Conclusions: AES occurred sporadically in Rajasthan, samples should be tested first for herpes group of viruses followed by EV or/and for arboviruses depending on season or measles, mumps and RVs in children.

A 14-year-old previously healthy female was transferred from a local emergency department after being found unresponsive at home. Parental questioning revealed she had fever and pharyngitis 2 weeks before presentation. Past mental health history was negative, including concern for past or present suicidal ideation/attempts, suspected substance use, or toxic ingestion. In the emergency department, she was orotracheally intubated due to a Glasgow Coma Scale of 3. She was hemodynamically stable and euglycemic. Electrocardiogram showed sinus tachycardia. She underwent a noncontrast head computed tomography that was normal and subsequently underwent a lumbar puncture. She had a seizure and was given a loading dose of diazepam and fosphenytoin that led to cessation of extremity movements. She was subsequently transferred to the PICU for additional evaluation. Initial examination without sedation or analgesia demonstrated dilated and minimally responsive pupils, intermittent decorticate posturing, and bilateral lower extremity rigidity and clonus, consistent with a Glasgow Coma Scale of 5. Serum studies were unremarkable with the exception of mild leukocytosis. Chest radiograph only showed atelectasis. She was empirically started on antibiotics to cover for meningitis pending final cerebral spinal fluid test results. The pediatric neurology team was consulted for EEG monitoring, and the patient was eventually sent for computed tomography angiogram and magnetic resonance angiogram/venogram. We will review diagnostic evaluation and management of an adolescent patient with acute encephalopathy with decorticate posturing of unclear etiology., (Copyright © 2017 by the American Academy of Pediatrics.)
