During a canine distemper virus (CDV) outbreak in raccoons (Procyon lotor) from Cook County, Illinois, a juvenile female suffering from seizures was killed and necropsied. Gross and histologic findings of necrotizing encephalitis and proliferative bronchopneumonia were attributed to CDV infection and considered the cause of clinical signs. A section of cerebellum stained immunohistochemically for Neospora caninum revealed an approximately 40 microm diameter, round to oval cyst with a 2- to 3-microm-thick wall and filled with 1-2 microm diameter, round to oval bradyzoites. Polymerase chain reaction (PCR) results were positive for N. caninum using DNA extracted from the brain. Specific PCR for the closely related organisms Toxoplasma gondii and Hammondia heydorni yielded negative results. This case report provides histologic, immunohistochemical, and molecular evidence that raccoons are a naturally occurring intermediate host of N. caninum.

Phenobarbital (PB) has a reputation for safety, and it is commonly believed that PB-related increases in serum aminotransferase levels do not indicate or predict the development of significant chronic liver disease. Here we report of two adult patients with a long history of epilepsy treated with PB who died suddenly: one as consequence of cardiac arrest, the other of acute bronchopneumonia. At autopsy, analysis of liver parenchyma revealed rich portal inflammatory infiltrate, which consisted of mixed eosinophil and monocyte cells, associated with several foci of necrosis surrounded by a hard ring of non-specific granulomatous tissue. Inflammatory reactions of internal and external hepatic biliary ducts were also seen. Our findings illustrate that PB may be associated with chronic liver damage, which may lead to more serious and deleterious consequences. For this reason, each clinician should recognize this entity in the differential diagnosis of PB-related asymptomatic chronic hepatic enzyme dysfunction.

A 5-year-old male, drowsy, jaundiced child presented with fulminant hepatitis and had HAV and HEV infection. He had hepatic encephalopathy grade 1, fever, pallor, hypotension, crepitations in his right lung base and hepatosplenomegaly with dyspnoea. He had highly raised liver enzymes and hypoalbuminemia (2.8 g/dl) but anemia (hemoglobin of 7.7 g/dl and 5.7 g/dl 2 days later), reticulocytopenia and severe thrombocytopenia (44 x 10(9)/l) were unexplained. Parvovirus B19-specific IgM antibodies and B19 DNA were found in the serum of the child. Chest X-ray showed pleural effusion and bronchopneumonia, while blood culture isolated coagulase-negative staphylococci (BACTEC 9120) and he had low oxygen saturation. Hence, he was treated with IV amoxicillin+ clavulinic acid and oxygen inhalation. He had seizures and cardiac arrest but was revived. On the third day his condition worsened and the child died despite intensive care. Hence it is concluded that his anemia and thrombocytopenia were B19 induced and this might have aggravated or caused fulminant hepatitis.

Owing to the large size of chromosome 2, partial monosomy of the long arm of this chromosome gives rise to many specific phenotypes. We report on a 2-month-old girl with an interstitial deletion of 2q24.2q24.3, which was confirmed by microarray-based comparative genomic hybridization analysis. The patient showed delayed growth and mental retardation, early myoclonic seizures, and characteristic dysmorphic features including thick arched eyebrows, upslanting palpebral fissures, long eyelashes, depressed nasal bridge, short nose, long philtrum, small mouth, micrognathia, and low set ears. Her early myoclonic seizures were likely due to haploinsufficiency of SCN1A and SCN2A, which are included in the deletion region. When she experienced acute bronchopneumonia, she showed severe pulmonary emphysema. The deletion region of 2q24.2 includes the integrin beta6 gene (ITGB6), which may prevent acute lung injury and pulmonary emphysema. Many previously reported patients with deletions of 2q24.2 showed poor outcomes because of respiratory failure. These observations suggest the possibility of a strong relationship between haploinsufficiency of ITGB6 and pulmonary dysfunction.

Two infants developed encephalitis in the late neonatal period due to human parechovirus type 3 (HPeV-3). This finally resulted in intractable seizures leading to death. Both presented with classical signs and symptoms. HPeV-3 was detected in nasopharyngeal and rectal swabs, cerebrospinal fluid, serum and postmortem samples (for one infant). Ultrasound and magnetic resonance imaging findings showed severe white matter injury in one infant, and limited hippocampal injury in the other. Parents consented to autopsy in the latter, showing diffuse gliotic oedema of cerebral white matter, bilateral bronchopneumonia, and inflammation in spleen. We emphasise that polymerase chain reaction (PCR) testing for parechovirus in neonates with severe sepsis-like syndrome and meningoencephalitis is mandatory.

Human bocavirus (HBOV) has been reported as a worldwide distributed respiratory pathogen. It has also been associated with encephalitis recently by detection of the virus in cerebrospinal fluid (CSF) of patients presented with encephalitis. This retrospective study aimed to present clinical features of HBOV infections in children with respiratory symptoms and describe unexplained encephalopathy in a subgroup of these patients. Results of 1,143 pediatric nasal samples from mid-December 2013 to July 2014 were reviewed for detection of HBOV. A multiplex real time polymerase chain reaction assay was used for viral detection. Medical records of the patients were retrospectively analyzed. HBOV was detected in 30 patients (2.6%). Median age was 14 months (5-80). Clinical diagnoses were upper respiratory tract infection (n = 10), bronchopneumonia (n = 9), acute bronchiolitis (n = 5), pneumonia (n = 4), acute bronchitis (n = 1), and asthma execarbation (n = 1). Hospitalization was required in 16 (53.3%) patients and 10 (62.5%) of them admitted to pediatric intensive care unit (PICU). Noninvasive mechanical ventilation modalities was applied to four patients and mechanical ventilation to four patients. Intractable seizures developed in four patients while mechanically ventilated on the 2nd-3rd days of PICU admission. No specific reason for encephalopathy was found after a thorough investigation. No mortality was observed, but two patients were discharged with neurological sequela. HBOV may lead to respiratory infections in a wide spectrum of severity. This report indicates its potential to cause severe respiratory infections requiring PICU admission and highlights possible clinical association of HBOV and encephalopathy, which developed during severe respiratory infection.
