RESULTS: Based on 517 cases of AFP reported during this 5-year period, the overall rate of AFP was 1.2 per 100 000 children below 15 years old. The major clinical diagnosis associated with AFP were Guillain-Barre syndrome (30.2%), central nervous system infection (16.2%), transverse myelitis (10.6%) non-polio enterovirus infection (6.2%), and hypokalaemic paralysis (5.2%). This unusual pattern with an excess of CNS infection and non-polio enterovirus infection was attributed to the outbreak of enterovirus 71 infection nation-wide in 1997. According to the WHO virological classification, there was no case of poliomyelitis due to wild poliovirus. Three cases were 'polio compatible', there were no cases of vaccine-associated paralytic polio (VAPP), while 62 cases (12.0%) were merely classified as 'non-polio AFP'.
CONCLUSION: Overall, these data suggest the absence of circulation of wild poliovirus in Malaysia from 1997 to 2001. The pattern of AFP in this study is different from other published reports.
OBJECTIVES: Work-related disability is common in persons with spinal cord injury (SCI). The aims of this study are to examine the associations of employment with self-perceived health (SPH) and quality of life (QoL) across 22 countries and to explore the covariates around employment and SPH and QoL.
SETTING: Community.
METHODS: We analyzed 9494 community-dwelling persons with SCI aged 18-65. We performed an adjusted regression and path analysis. The independent variable was 'employment' and the dependent variables were two single items: QoL (very poor to very good) and SPH (excellent to poor). Covariates included the Gross Domestic Product (GDP), education, time since SCI, age, gender, years of employment after SCI, SCI level (paraplegia, tetraplegia), and completeness of SCI.
RESULTS: Participants' mean age was 47, 74% were male, and 63% had paraplegia. We found an association between employment and QoL and SPH. While the magnitude of the effect of employment on QoL did not differ across GDP quartiles, its perceived effect on QoL was found to be significant in the highest GDP quartile. Employment was predictive of good SPH in two GDP quartiles (Q1 and Q4), but significant across all quartiles when predicting poor perceptions, with the magnitude of effect varying significantly.
CONCLUSIONS: Employment is closely related to QoL and SPH depending on the GDP. We may positively influence the QoL and SPH in the SCI population to promote better employment outcomes by considering the infrastructure and economy.
METHODS: In this study, 0.05 mM KA was administered at dose of 10 µL/100 g body weight, at a rate of 10 µL/min, to induce spinal injury by intra-spinal injection between the T12 and T13 thoracic vertebrae. In this protocol, detailed description of a dorsal laminectomy was explained to expose the spinal cord, following intra-spinal kainic acid administration at desired location. The dose, rate and technique to administer kainic acid were explained extensively to reflect a successful paraplegia and spinal cord injury in rats. The postoperative care and complication post injury of paraplegic laboratory animals were also explained, and necessary requirements to overcome these complications were also described to help researcher.
RESULTS: This injury model produced impaired hind limb locomotor function with mild seizure. Hence this protocol will help researchers to induce spinal cord injury in laboratories at extremely low cost and also will help to determine the necessary supplies, methods for producing SCI in rats and treatments designed to mitigate post-injury impairment.
CONCLUSIONS: Kainic acid intra-spinal injection at the concentration of 0.05 mM, and rate 10 µL/min, is an effective method create spinal injury in rats, however more potent concentrations of kainic acid need to be studied in order to create severe spinal injuries.
