Disease Sequelae (disease + sequelae)
Selected AbstractsNeuropsychology of academic and behavioural limitations in school-age survivors of bacterial meningitisDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 11 2004Irene Koomen MD Neuropsychological impairments possibly underlying academic and/or behavioural limitations were studied in 149 school-age survivors of bacterial meningitis, 68 with and 81 without academic and/or behavioural limitations. Academic limitations affected mathematics, reading, and writing. Behavioural limitations were inferred from scores in the clinical range on the Child Behaviour Checklist. These children had been selected from a cohort of 674 children (57% males) who had recovered from non- Haemophilus influenzae type B bacterial meningitis and who had a mean age at infection of 2 years 4 months (range 1mo to 9y 5mo). They had neither,complex onset'meningitis, prior cognitive or behavioural problems, nor severe disease sequelae. They were assessed with standardized assessment methods a mean of 7.8 years (range 4 to 10.4) after meningitis. Children with limitations (32% of the cohort) performed generically poorly on measures of cognitive functioning, speed, and motor steadiness, rather than having impairments in specific neuropsychological domains. The presence of two or more minor neurological signs was more frequent in the group with than in the group without limitations (30% versus 9%); this may explain the relatively poor speed and motor steadiness of the group with limitations. [source] Detection and Management of an Outbreak of Equine Herpesvirus Type 1 Infection and Associated Neurological Disease in a Veterinary Teaching HospitalJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 5 2010L.S. Goehring Background: Because of the serious disease sequelae associated with equine herpesvirus type 1 (EHV-1) infections, awareness and control measures used to control outbreaks are important issues for all horse populations. Objectives: Describe the occurrence and management of an outbreak of EHV-1 infection at a veterinary hospital. Animals: Horses hospitalized at a referral veterinary hospital. Methods: A horse with myeloencephalopathy associated with EHV-1 infection (EHM) was admitted for diagnostic evaluation and treatment under strict infection control procedures. We describe the occurrence and management of a nosocomial outbreak of EHV-1 infections associated with admission of this patient. Results: Despite institution of rigorous biosecurity precautions at the time of admission of the index case, EHV-1 infections spread to 6 other horses that were hospitalized at the James L. Voss Veterinary Teaching Hopsital, including 2 that served as sources of infection for horses on their home premises after discharge. Infection with EHV-1 was confirmed by polymerase chain reaction (PCR) and by seroconversion documented by glycoprotein G ELISA. A voluntary quarantine was imposed and admissions were restricted to prevent additional horses from being exposed. Quarantine duration was abbreviated by serial testing of all horses with PCR. Conclusions and Clinical Importance: These findings illustrate the contagious disease risk that can accompany management of horses with EHM. Horses with active nasal EHV-1 shedding should be isolated in an airspace that is separate from other horses by strictly enforced biosecurity and isolation procedures. Serial testing with PCR may be a useful adjunct to determine when the risk of transmission has been minimized.

Methods:,A 31-item survey was administered to a convenience sample of people with PD recruited through Parkinson's NSW Inc. and its support groups. Results:,Four hundred and forty-four responses were received. Sexual limitations were reported by 73.5% of people with PD. Additionally, respondents indicated that health professionals did not necessarily understand what it is like to live with the disease. Conclusions:,Movement problems are most often presented as the major sequelae of PD. This study shows that for a large proportion of sufferers, sexual limitations are an issue. Additionally, it is important for health professionals to provide ample opportunity for the discussion of these difficulties. [source] Verotoxin 1 binding to intestinal crypt epithelial cells results in localization to lysosomes and abrogation of toxicityCELLULAR MICROBIOLOGY, Issue 2 2003D. E. Elaine Hoey Summary Verotoxins (VTs) are important virulence factors of enterohaemorrhagic Escherichia coli (EHEC), a group of bacteria associated with severe disease sequelae in humans. The potent cytotoxic activity of VTs is important in pathogenicity, resulting in the death of cells expressing receptor Gb3 (globotriaosylceramide). EHEC, particularly serotype O157:H7, frequently colonize reservoir hosts (such as cattle) in the absence of disease, however, the basis to avirulence in this host has been unclear. The objective of this study was assessment of interaction between VT and intestinal epithelium, which represents the major interface between the host and enteric organisms. Bovine intestinal epithelial cells expressed Gb3 in vitro in primary cell cultures, localizing specifically to proliferating crypt cells in corroboration with in situ immunohistological observations on intestinal mucosa. Expression of receptor by these cells contrasts with the absence of Gb3 on human intestinal epithelium in vivo. Despite receptor expression, VT exhibited no cytotoxic activity against bovine epithelial cells. Sub-cellular localization of VT indicated that this toxin was excluded from endoplasmic reticulum but localized to lysosomes, corresponding with abrogation of cytotoxicity. VT intracellular trafficking was unaffected by treatment of primary cell cultures with methyl-,-cyclodextrin, indicating that Gb3 in these cells is not associated with lipid rafts but is randomly distributed in the membrane. The combination of Gb3 isoform, membrane distribution and VT trafficking correlate with observations of other receptor-positive cells that resist verocytotoxicity. These studies demonstrate that intestinal epithelium is an important determinant in VT interaction with major implications for the differential consequences of EHEC infection in reservoir hosts and humans.
