A 46 years, nondiabetic, nonhypertensive woman presented with headache, vomiting, low grade intermittent fever, behavioral abnormality and seizures for last three months. Clinically she had meningism with bilateral papilloedema. Based on CSF analysis, normal CT scan of brain and suspicious lesion in X-ray chest, she was put on anti-tuberculosis therapy. As the patient further deteriorated clinically, MRI of brain was carried out and revealed bilateral increased signal intensities in both medial temporal lobes in T2 and flair sequences. Inj. acyclovir was added considering the diagnosis of herpes simplex encephalitis. In spite of receiving treatment patient gradually became more drowsy and repeat X-ray chest with CT guided FNAC showed picture of adenocarcinoma of lung. So finally, we concluded it to be a case of limbic encephalitis.

Proliferation of the lymphoid system should arouse suspicion of a potentially serious illness. We present a 4.5-year-old boy who developed fever, vomiting, diarrhea, lymphadenopathy, hepatosplenomegaly, lymphocytosis, anemia, thrombocytopenia, and increased liver enzymes. Lymph node and bone marrow biopsies showed lymphoproliferation, Epstein-Barr virus (EBV) infection, and hemophagocytosis leading to the diagnosis of hemophagocytic lymphohistiocytosis (HLH). Chemotherapy was initiated for HLH with dexamethasone, etoposide, and cyclosporine. Because of a high level of EBV viremia, rituximab was added a few days later and resulted in a remarkable drop in the EBV in the circulation but not in the cerebrospinal fluid. However, the patient succumbed to encephalitis, pneumonia, and cardiopulmonary failure. Autopsy revealed the presence of EBV in the brain, indicating the ineffectiveness of rituximab therapy in treating central nervous system infection with EBV.

Here we describe a case of Reye syndrome diagnosed at postmortem liver biopsy of a three-year old girl who presented with vomiting, low grade fever for three days and loss of consciousness for 18 hours. Clinically, the differential diagnoses were meningitis, encephalitis and septicemia. No history of past illness or any drug ingestion including aspirin were present. Laboratory investigations indicated a diagnosis of Reye syndrome. The child was given supportive treatment but died after two days of admission and postmortem needle-biopsy of the liver showed microvesicular steatosis consistent with Reye syndrome.

Panayiotopoulos syndrome is a common multifocal autonomic childhood epileptic disorder with significant clinical, pathophysiological and management implications. It affects otherwise normal children with onset at around 3-6 years. It is characterized by seizures, often prolonged, with predominantly autonomic symptoms and mainly ictal vomiting. EEG shows shifting and/or multiple foci, often with occipital dominance. Despite characteristic clinical and EEG manifestations Panayiotopoulos syndrome is often confused with occipital epilepsy and acute non-epileptic disorders such as encephalitis, syncope, cyclic vomiting or atypical migraine. This review aims to describe Panayiotopoulos syndrome on the basis of independent major studies and provide clinical clues for diagnosis and management.

Posterior reversible encephalopathy syndrome (PRES) is described neurological condition identifiable by clinical and radiological presentation. It occurs due to elevated blood pressure which exceeds auto-regulatory capacity of brain vasculature. PRES is characterized by headache, confusion, seizures, and altered mental function. In this report we describe a case of eleven-year-old boy who was hospitalized, because of nausea, vomiting, intermittent fever, headache, confusion and distress. Because of suspicion of encephalitis CT and MRI examinations were performed immediately where was established diagnose of PRES syndrome.

Cardioviruses (e.g., Theiler's murine encephalomyelitis virus [TMEV]) are members of the Picornaviridae family that cause myocarditis and encephalitis in rodents. Recently, several studies have identified human cardioviruses, including Saffold virus (SAFV) and a related virus named human TMEV-like cardiovirus (HTCV). At least eight cardiovirus genotypes are now recognized, with SAFV and most strains of HTCV belonging to genotypes 1 and 2, respectively; genotype 2 strains are the most common in the population. Although a genotype 3 cardiovirus has recently been cultured (SAFV-3), the genotype 1 and 2 cardioviruses have been difficult to propagate in vitro, hindering efforts to understand their seroprevalence and pathogenicity. Here we present the isolation and characterization of a genotype 2 human cardiovirus (HTCV-UC6). Notably, successful cultivation of HTCV-UC6 from stool required the addition of cytokine-blocking antibodies to interrupt downstream antiviral pathways. Unlike SAFV-3, HTCV-UC6 exhibited slow replication kinetics and demonstrated only a moderate cytopathic effect. Serologic assays revealed that 91% of U.S. adults carry antibodies to the genotype 2 cardioviruses, of which 80% generate neutralizing antibodies, in agreement with previous data showing that cardiovirus infection is widespread in humans. We also demonstrate an acute cardiovirus seroconversion event in a child with diarrhea and vomiting, thus reporting for the first time evidence linking cardiovirus infection to diarrheal disease in humans.

An unusual number of cases of rhomb encephalitis have occurred in Chile because of the increased frequency of infections caused by Listeria monocytogenes. We report three females aged 36, 40 and 55 years, with the disease. All presented with a prodrome characterized by headache, nausea, vomiting and fever, followed by ataxia and unilateral palsies of the third, seventh and twelfth cranial nerves. One patient presented also a hemi-hypoesthesia. Magnetic resonance showed lesions in the posterior aspect of the brain stem, specifically in relation to the floor of the fourth ventricle. Blood cultures were positive for Listeria monocytogenes.

Rotavirus, one of the major causes of severe gastroenteritis in children, occasionally causes central nervous system complications. Recently several patients with acute encephalitis/encephalopathy due to rotavirus associated with cerebellar signs and symptoms have been reported. The condition is characterized by disturbances of consciousness at onset and cerebellar signs and symptoms such as hypotonia, ataxia, dysmetria, and speech disorders, including mutism, slow speech, and dysarthria at convalescence. We report two patients (3-year-old girl, 2-year-old boy) who developed acute encephalitis due to rotavirus and showed cerebellar signs and symptoms. Both patients had characteristic history of consciousness disturbances subsequent to several days of diarrhea, vomiting and fever, and cerebellar symptoms such as hypotonia, ataxia, dysmetria, and speech disorders during the recovery period. Electroencephalography showed diffuse high-voltage delta wave activity in each patient. Brain magnetic resonance imaging showed cerebellar edema in the acute phase followed by cerebellar atrophy on follow-up images in both patients. In the first patient, diffusion-weighted images (DWI) revealed high signals at the left cerebellar peduncle region and apparent diffusion coefficient (ADC) maps showed decreased ADC values of the lesion in the acute phase. The first patient had dysmetria at 1-year follow-up. However, she had normal motor and cognitive functions and could lead her daily life without impairment. In the second patient, no further symptoms were apparent at 1-year follow-up. Acute encephalitis/encephalopathy due to rotavirus with cerebellar signs and symptoms might be diagnosed on DWI, by demonstrating decreased ADC values in acute phase.

Phenytoin can produce significant dose-related toxicity because of its zero order pharmacokinetics and is an important issue in pediatric emergency medicine. It is important to differentiate phenytoin toxicity manifesting with symptoms like fever, vomiting, seizures, ataxia masquerading as acute meningo-encephalitic illness, more so at centers where facilities to measure serum phenytoin levels are not available. Here we describe two children with phenytoin toxicity, presenting to the emergency department with features suggestive of acute meningo-encephalitis.

In 2010 the High Court of Australia in Tabet v Gett (2010) 240 CLR 537 determined an appeal in a medical negligence case concerning a six-year-old girl who had presented to a major paediatric hospital with symptoms over several weeks of headaches and vomiting after a recent history of chicken pox. The differential diagnosis was varicella, meningitis or encephalitis and two days later, after she deteriorated neurologically, she received a lumbar puncture. Three days later she suffered a seizure and irreversible brain damage. A CT scan performed at that point showed a brain tumour. As Australia does not have a no-fault system providing compensation to cover the long-term care required for such a condition, the girl (through her parents and lawyers) sued her treating physician. She alleged that, because a cerebral CT scan was not performed when clinically indicated after the diagnosis of meningitis or encephalitis and before the lumbar puncture, she had "lost the chance" to have her brain tumour treated before she sustained permanent brain damage. She succeeded at first instance, but lost on appeal. The High Court also rejected her claim, holding unanimously that there were no policy reasons to allow recovery of damages based on possible (less than 50%) "loss of a chance" of a better medical outcome. The court held that the law of torts in Australia required "all or nothing" proof that physical injury was caused or contributed to by a negligent party. The High Court, however, did not exclude loss of chance as forming the substance of a probable (greater than 50%) claim in medical negligence in some future case. In the meantime, patients injured in Australia as a result of possible medical negligence (particularly in the intractable difficult instances of late diagnosis) must face the injustice of the significant day-to-day care needs of victims being carried by family members and the taxpayer-funded public hospital system. The High Court in Tabet v Gett again provides evidence that, as currently constituted, it remains deaf to the injustice caused by State legislation excessively restricting the access to reasonable compensation by victims of medical negligence.
