Cerebral salt wasting syndrome can occur in children with encephalitis. Clinicians should be aware of hyponatremia in patients who develop polyuria with the signs of dehydration and deteriorated consciousness. Furthermore, patients who present with status epilepticus or who are suspected to have high intracranial pressure may have an increased risk of cerebral salt wasting syndrome.

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain...

BACKGROUND: Directly-transmitted rodent-borne zoonotic viruses, such as lymphocytic choriomeningitis virus (LCMV) can cause nervous system infections. Rodent-borne Ljungan virus (LV) is considered potentially zoonotic possibly causing neurological symptoms. Our objective was to understand the role of these two viruses compared to other pathogens in causing neurological infections in Finnish patients. METHODS: Routine screening data were available for 400 patients aged 5-50 years, collected from December 2013-December 2014 with suspected neurological infection...

Mycoplasmas of humans and animals are usually associated with respiratory, autoimmune, genital and joint diseases. Human mycoplasmas have also been known to affect the brain. Severe central nervous system (CNS) diseases, such as encephalitis, have been linked to Mycoplasma pneumoniae and ureaplasma infections. Less well known is the sheep and goat pathogen, Mycoplasma agalactiae, which has been found in large quantities in the brain where it may be responsible for non-purulent encephalitis as well as ataxia in young animals...

BACKGROUND: Clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinico-radiological syndrome characterized by transient mild symptoms of encephalopathy and a reversible lesion in the splenium of the corpus callosum on magnetic resonance imaging (MRI). It is often triggered by infection. The common pathogens of MERS are viruses, especially influenza virus. However, Mycoplasma pneumoniae (M.pneumoniae) are relatively rare pathogens for MERS. CASE PRESENTATION: Here we report two paediatric cases of M...

A broad range of neurologic disorders has been described in children infected with Mycoplasma pneumoniae, of which encephalitis is among the most common. In contrast, the association between optic neuritis and Mycoplasma pneumoniae infection has been rarely described in children. We report a case of a 12-year-old girl who was seropositive for antibodies against Mycoplasma pneumoniae and presented with optic neuritis without respiratory symptoms or other neurologic findings.

Investigations of patients with suspected Mycoplasma pneumoniae infection have been undertaken in England since the early 1970s. M. pneumoniae is a respiratory pathogen that is a common cause of pneumonia and may cause serious sequelae such as encephalitis and has been documented in children with persistent cough. The pathogen is found in all age groups, with higher prevalence in children aged 5-14 years. In England, recurrent epidemic periods have occurred at ~4-yearly intervals. In addition, low-level sporadic infection occurs with seasonal peaks from December to February...

The list of extrapulmonary manifestations due to Mycoplasma pneumoniae infection can be classified according to the following three possible mechanisms derived from the established biological activity of M. pneumoniae; (1) a direct type in which the bacterium is present at the site of inflammation and local inflammatory cytokines induced by the bacterium play an important role (2) an indirect type in which the bacterium is not present at the site of inflammation and immune modulations, such as autoimmunity or formation of immune complexes, play an important role, and (3) a vascular occlusion type in which obstruction of blood flow induced either directly or indirectly by the bacterium plays an important role...

Histophilus somni is responsible for sporadic disease worldwide in cattle and, to a lesser extent, in small ruminants, bighorn sheep (Ovis canadensis), and North American bison (Bison bison). The importance of H. somni diseases can be attributed to improved clinical and laboratory recognition, combined with the growth in intensive management practices for cattle. Although outbreaks of bovine histophilosis can occur year-round, in northern and southern hemispheres, it is most frequent in late fall and early winter...

We report a case of a child whose EEG demonstrated extreme spindles (ES) after acute lymphoblastic leukemia treatment. This finding has not been reported previously. In 1962, Gibbs and Gibbs described the ES EEG pattern due to its high amplitude (200 to 400 μV). ES are a rare spindle variant that is found in EEGs of 0.05% of normal children (average age, 3 years, with a range of 1 to 12 years), and are even rarer after 11 years. Moreover due to changes in the white matter of the frontal lobe, ES have been associated with such conditions as cerebral palsy and mental retardation, residual brain damage, undefined infections, infantile neuroaxonal dystrophy, Menkes' kinky-hair syndrome, congenital muscular dystrophy, hydrocephalus, porencephaly, epilepsy, progressive cerebellar degeneration, and mycoplasma encephalitis...

Anti-N-methyl-D-aspartate-receptor (NMDA-R) encephalitis is a new autoimmune, often paraneoplastic disorder that presents with complex neuropsychiatric symptoms. It was first described in 2007 by Dalmau et al. Our patient presented with headache, behavioral changes and then seizures with hallucinations. She was initially misdiagnosed to have schizophrenia and was prescribed antipsychotics. She deteriorated and developed further seizures with hypoventilation and choreoathetosis. Her blood investigations were positive for mycoplasma IGM...

We report seven children with recent Mycoplasma pneumoniae infection and severe Guillain-Barré syndrome (GBS) that presented to two European medical centres from 1992 to 2012. Severe GBS was defined as the occurrence of respiratory failure, central nervous system (CNS) involvement, or death. Five children had GBS, one Bickerstaff brain stem encephalitis (BBE), and one acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP). The five patients with severe GBS were derived from an original cohort of 66 children with GBS...
