Traumatic spinal cord injuries in Turkey.

Spinal cord lesions have various aetiologies, and trauma is one of the leading causes. Patients with spinal cord injuries (SCI) often have motor, sensory and autonomic dysfunctions and require a multidisciplinary rehabilitation programme. In this study 1694 SCI patients were investigated, including the frequency, and the distribution by age, sex, profession, aetiology, clinical status and year of occurrence. Traumatic SCI is more frequent among males than females and among those between the ages of 15 and 39 years. Regarding the aetiology, traffic accident comprised 35.41% of the total cases, the second most common cause was falls with 29.51%, and the third was high velocity bullet wounds: 21.95%.     

Theophylline for Bradycardia Secondary to Cervical Spinal Cord Injury

Background  

Spinal cord injury (SCI) is a devastating disease process that can occur as a consequence of motor vehicle collisions, falls, or other traumatic injuries. Persistent bradycardia was found to be universally present in all high cervical SCI patients. Limited data exists to suggest the most effective therapy for the bradycardia associated with high cervical SCI. Treatment includes atropine, epinephrine, dopamine, and even implantable cardiac pacemakers, all of which have their risks and side effects. There are no prospective studies to evaluate methylxanthines for the treatment of bradycardia secondary to cervical SCI.     

Contribution of incidence to increasing prevalence of multiple sclerosis in Alberta, Canada

Alberta Health Care Insurance Plan (AHCIP) data were used to calculate prevalence and incidence rates for multiple sclerosis (MS) in the general population of Alberta from 1990 to 2004. Multiple sclerosis prevalence rose steadily each year over this time period, from 217.6/100,000 individuals in 1990 to 357.6/100,000 in 2004. Multiple sclerosis incidence fluctuated with a slight increase from 1990 to 2004, at 20.9/100,000 and 23.9/100,000, respectively. Age-specific prevalence rates were higher between ages 30 and 60 in 2004 than in 1990. The pattern of age-specific incidence rates was similar in 1990 and 2004, with a slight shift toward diagnosis in younger years. Gender-specific prevalence rates were higher for females in both 1990 and 2004, with a greater increase in females (43%) than males (29%). Gender-specific incidence rates were higher for females than males in both years, but there was no differential increase in incidence by gender from 1990 to 2004. The 2004 Alberta MS prevalence rate remains among the highest reported worldwide. Both increasing incidence and longer duration have likely contributed to increasing MS prevalence in the province.     

Severe traumatic brain injury in a large Canadian health region

BACKGROUND: Although severe traumatic brain injury (sTBI) is a devastating condition with tremendous public health implications, the epidemiology of this disease has not previously been described in Canada. We sought to define the incidence, risk factors and outcome of patients suffering sTBI in a large Canadian region. METHODS: A population-based surveillance cohort design was utilized to identify all Calgary Heath Region residents who were victims of trauma with an injury severity score > or = 12. Subsequent application of a specific sTBI case definition defined the final cohort. RESULTS: The annual incidence of sTBI was 11.4 per 100,000 population. The incidence of sTBI was significantly higher for males as compared to females [17.1 vs. 5.9 per 100,000; relative risk (RR) = 2.91, 95% confidence interval; 2.17, 3.94; p<0.0001]. There was a striking increase in the annual age specific population incidence of sTBI observed among those older than 74 years of age. The relative risk among the highest risk group of elderly (>85 years) males as compared to the lowest risk female group (50-64 years) was 19.78 (95% CI; 6.27, 62.3; p<0.0001). One hundred and eight patients died prior to hospital discharge for a mortality rate of 5.1 per 100,000 per year. CONCLUSIONS: Severe traumatic brain injury is common among residents of the Calgary Health Region and is associated with a high mortality rate. Males and the elderly are at the highest risk for acquiring sTBI and may represent target groups for preventive efforts.     

The incidence of injuries in persons with and without epilepsy—A population‐based study

Purpose: To compare the 1‐year population‐based incidence and types of injuries in persons with and without epilepsy. Methods: Three administrative databases (inpatient visits, physician claims, and emergency room visits) were linked from fiscal years 1996–2003 using a provincial insurance plan registry, which captures 99% of a population of 1.4 million in a large Canadian health region. Epilepsy cases (all age groups) from fiscal year 1996–2002 were identified. Three people without epilepsy were matched to one person with epilepsy for age (±1 year) and sex. Injuries were defined as any of 16 types of injuries for which medical attention was sought that occurred within fiscal year 2003. Results: Eight thousand eight hundred ninety subjects with epilepsy were identified and matched to 26,670 controls for age and sex. The mean age was 37.4 years (range 0.01–96.4 years), and 51.3% of subjects were male. The 1‐year incidence of one or more injuries was 20.6% among persons with epilepsy and 16.1% among those without epilepsy (p < 0.001). Of the 16 types of injuries studied, 11 were higher in persons with epilepsy compared to those without epilepsy, and included fractures, crushing injuries, intracranial injuries, other types of head injuries, and multiple injuries. The difference was still significant after adjusting for age, gender, and comorbidities. Discussion: The 1‐year incidence of injuries in this study was greater in persons with epilepsy compared to those without epilepsy, for nearly all injury types. Injury prevention should be discussed during routine visits in persons with epilepsy.     

The older adult with a spinal cord injury.

Sixty-two consecutive acute spinal cord injury (SCI) patients who were aged 55 years or older were studied and compared to 296 SCI patients of age less than 55 years. Compared to younger patients, the older group had significantly more females (29%), preexisting medical conditions (87%), associated injuries (55%), incomplete quadriplegic patients (63%), and persons whose injuries resulted from falls (53%). There were no differences between groups in frequency of ventilator use, occurrence of medical complications, or acute length of stay, but older patients tended to have fewer surgical spinal fusions (40%), shorter rehabilitation stays (66.5 days), more indwelling urethral cathteters (31%), and more nursing home discharges (19%). With other factors being controlled, advancing age was predictive only of nursing home discharge, and not of acute or rehabilitation lengths of stay. Among older SCI patients, those with complete injuries were nearly 3 times as likely to have been discharged to nursing homes in our series compared to older patients with incomplete lesions. Although many aspects of the presentation, course, and care of older SCI individuals are similar to those of younger patients, there are several unique features of older adults with a SCI.     

Spinal cord injuries in Taipei, Taiwan, 1978-1981

This survey of spinal cord injuries in Taipei city from January 1978 to December 1981 was carried out by a review of the hospital records. During these four years 560 patients with acute spinal cord injury (SCI) were admitted to the hospitals in the city of Taipei. Of these, 123 were inhabitants of Taipei city, showing the annual incidence of SCI in Taipei to be 14.6 per million population. As a result of injury 118 patients were paraparetic, 180 were paraplegic, 117 tetraparetic and 145 were tetraplegic. The average age was 36 years and 2 months and one third were in the 20 to 29 year age group. The male/female ratio was 4.9. The causes of SCI were traffic accidents (44.5%), accidental falls (28.5%), struck by object (14.6%) and sports injury (3.4%). The mortality rate was 6.0%. Respiratory complication was the leading cause of death, accounting for 58% of the total deaths.     

Factors in the rising prevalence of multiple sclerosis in the north-east of Ireland

BACKGROUND: Northern Ireland is recognized as an area of high risk for multiple sclerosis. The original study of Allison and Millar in 1951 found a prevalence of 51/100,000 and mean annual incidence of 2.74/100,000/year. Subsequent studies in 1961, 1986, and 1996 suggested rising prevalence--80, 138, and 168.2/100,000, respectively. METHODS: In 2004, we surveyed the North-East of Northern Ireland (population 160,446, area 2030 km(2)) using multiple sources of case ascertainment, all satisfying the Poser criteria for definite or probable multiple sclerosis (MS) or the McDonald criteria. RESULTS: From a provisional list of 469 cases, 370 (123 males, 247 females) were identified. The prevalence was 230.6 per 100,000 (95% CI 207.0-255.4) with significantly higher prevalence in females (300.8/100,000) than males (157.0/100,000). Direct standardization to the 1961 Northern Ireland population reduced the overall prevalence rate to 200.5/100,000 (95% CI 193.2-208.0), in females to 270.2/100,000 (95% CI 258.8-282.4) and in males to 131.1/100,000 (95% CI 122.8-139.9). In 1996, incidence had risen to 9.3/100,000/year (14 cases in population of 151,000) with a higher incidence in females (10.3/100,000/year) than males (8.3/100,000/year). CONCLUSIONS: Northern Ireland continues to have a rising prevalence of MS. The increase in incidence suggests a true increase in the disease.     

An epidemiological study of children with status epilepticus in Okayama, Japan

BACKGROUND: The incidence of status epilepticus (SE) in Asian children, including Japanese, has not been reported. METHODS: In 2003, we performed an epidemiological study of SE on Japanese children (31 days or older to <15 years of age) in Okayama City by ascertaining all lifetime first episodes of SE. RESULTS: Thirty-seven patients (22 males and 15 females) were identified. The annual incidence of SE was 38.8 per 100,000 population (95% CI: 24.5-49.5). Febrile SE in the absence of CNS infection accounted for 17. Acute symptomatic etiologies other than febrile SE were observed in eight patients, including three cases of influenza encephalitis/encephalopathy. Five were classified as remote symptomatic and the remaining seven as cryptogenic. The highest incidence (155.1/100,000) was seen in the age range of 31 days or older to <1 year, followed by 101.5/100,000 in the age range of one year, and the incidence decreased after eight years. In 26 of the 37 patients, SE was their first seizure. As for seizure types, 32 had convulsive SE, including tonic status in one. Five others showed nonconvulsive SE, including complex partial SE in four and absence status in one. No one died of SE. Two patients who brought on SE because of influenza encephalitis/encephalopathy suffered from motor disturbance with or without mental disturbance after SE. CONCLUSIONS: The incidence of SE tended to be higher in Japanese children than reported in Caucasians. The Japanese had an age-specific incidence pattern similar to that of Caucasians.     

Achalasia: incidence,prevalence and survival. A population‐based study

Background Studies of achalasia epidemiology are important as they often yield new insights into disease etiology. In this study, our objective was to carry out the first North American population‐based study of achalasia epidemiology using a governmental administrative database. Methods All residents in the province of Alberta, Canada receive universal healthcare coverage as a benefit. The provincial health ministry, Alberta Health and Wellness, maintains a central stakeholder database of patient demographic information and physician billing claims. We defined an achalasia case as a billing claim submitted for the years 1996–2007 with an ICD‐9‐CM code of 530.0 or 530 and a Canadian Classification of Procedure treatment code of 54.92A (endoscopic balloon dilation) or 54.6 (esophagomyotomy). A preliminary validation study of the case definition demonstrated a sensitivity of 85% and specificity of 99% for known cases and controls. Key Results A total of 463 achalasia cases were identified from 1995 to 2008 (59.6% males). Mean age at diagnosis was 53.1 years. In 2007, the achalasia incidence was 1.63/100 000 (95% CI 1.20, 2.06) and the prevalence was 10.82/100 000 (95% CI 9.70, 11.93). We observed a steady increase in the overall prevalence rate from 2.51/100 000 in 1996 to 10.82/100 000 in 2007. Survival of achalasia cases was significantly less than age–sex matched population controls (P < 0.0001). Conclusions & Inferences Using a population‐based approach, the incidence and prevalence of treated achalasia is 1.63/100 000 and 10.82/100 000, respectively. The disease appears to have a stable incidence but a rising prevalence. Survival of achalasia cases is significantly less than age‐matched healthy controls.     

Respiratory management of pediatric patients with spinal cord injuries: retrospective review of the duPont experience

Pulmonary complications contribute to morbidity and mortality in spinal cord injuries (SCIs). A retrospective review of 20 years of experience with tracheostomy- and ventilator-dependent SCI children is presented. The authors developed and analyzed a database of 47 children (average age = 11.4 years). Of the patients, 27% had concomitant brain injuries, 6% had prior histories of reactive airway disease, and 2% had thoracic fractures. Injuries were caused by motor vehicle accidents (53%); gunshot wounds (19%); sports-related accidents (19%); and vascular injuries, transverse myelitis, or spinal tumors (8%). Of the injuries, 52% were high level (C1 to C2) and 48% were mid- or low level (C3 to C5). Two groups were analyzed for demographic information. Complications included tracheitis, atelectasis, and pneumonia. Mean tidal volume was 14 cm2/kg (maximum = 22 cm2/kg). Bedside lung function parameters were attempted to assess readiness and the rapidity of weans. T-piece sprints were used to successfully wean 63% of patients. Successfully weaned patients were compared with those not weaned. No deaths or readmissions for late-onset respiratory failure postwean occurred. The authors' clinical impression favors higher tidal volumes and aggressive bronchial hygiene to minimize pulmonary complications and enhance weaning. Successfully weaned patients had fewer complications. A critical pathway for respiratory management of SCI children is presented.     

A nationwide epidemiological study of spinal cord injuries in Taiwan from July 1992 to June 1996

Abstract

This prospective epidemiological survey of spinal cord injury (SCI) In Taiwan was carried out by recruiting patients attended by physicians from various medical centers and general hospitals all over Taiwan from july 1992 to june 1996. A total of 6,410 cases of traumatic spirtal fracture were registered among which were 1,586 new cases of SCI. The results represented 70% of the scope of SCI in Taiwan. The observed average annual incidence ofSCI in Taiwan was 18.8 per million population. The mean age was 46. 1 yearsold with a plateau distribution for over 20 years and older. Geriatric victims are a major group of SCI in Taiwan. The male to female ratio was 3 to 1. The leading causes of SCI were traffic accidents and accidental falls. Motorcycle collisions accounted for 62% of the traffic accidents, and as most of the motorcycle riders were not helmet users, head injüry became the major associated injury of SCI in Taiwan. The effectiveness of the comprehensive care system for SCI patients in Taiwan is relatively good, as reflected by the low rates of complications of SCI, the low mortality rate (6.6%), and the high percentage (67.4%) of SCI patients achieving self-care ultimately at home after rehabilitation. The analysis of person days healthy life loss and quality adjusted survival time revealed that SCI patients in Taiwan required 4 years to cope with the morbidity, and on average, could return to the main stream of life for another 30 years.

A community based study of the incidence of dementia in subjects aged 85 years and over.

The aim was to investigate the incidence rate of dementia for community residents aged 85 years and over. It was a two wave community study of 224 subjects (community residents including those residing in a nursing home) older than 85 years, restudied 4.1 years after a community prevalence study. A two stage method was used, comprising the mini mental state examination followed in a stratified sample by the geriatric mental state schedule (A3)/AGECAT. Incidence rates were based on person-years at risk. The overall incidence of dementia was 6.9 (95% confidence interval (95% CI) 4.8-9.1) per 100 person-years at risk. The incidence was significantly higher for women than for men; respectively 8.9 (95% CI 5.9-11.9) v 2.7 (95% CI 0.5-4.9) per 100 person-years at risk. In the fastest growing age group seven out of 100 persons develop dementia each year. Women, who constitute two thirds of the oldest old, seem to have a higher risk. Further research is needed into the risk factors for dementia in this age group.     

Affective disorders in motor neuron disease: a population-based study

Several studies have suggested that there may be an increased prevalence of affective disorders in people with motor neuron disease (MND). However, the literature is inconsistent, possibly because of small sample sizes in the existing studies. The Canadian province of Alberta has a universal health care system in which physician contacts are recorded along with ICD-9-CM diagnostic codes. In this analysis, diagnostic codes indicative of MND and affective disorders were used. Stratified analysis and logistic regression were used in the analysis. There were 336 cases of MND leading to a prevalence of 14.5 per 100,000 in provincial residents > or =20 years old. Affective disorders were identified in 8.6% of the total population during the same year. The crude odds ratio for affective disorders in MND was 2.3 (95% CI = 1.7-3.0). However, the prevalence of affective disorders declined with increasing illness duration.     

Some observations on whiplash injuries.

Motor vehicle accidents with a whiplash mechanism of injury are one of the most common causes of neck injuries, with an incidence of perhaps 1 million per year in the United States. Proper adjustment of head restraints can reduce the incidence of neck pain in rear-end collisions by 24%. Persistent neck pain is more common in women by a ratio of 70:30. Whiplash injuries usually result in neck pain owing to myofascial trauma, which has been documented in both animal and human studies. Headaches, reported in 82% of patients acutely, are usually of the muscle contraction type, often associated with greater occipital neuralgia and less often temporomandibular joint syndrome. Occasionally migraine headaches can be precipitated. Dizziness often occurs and can result from vestibular, central, and cervical injury. More than one third of patients acutely complain of paresthesias, which frequently are caused by trigger points and thoracic outlet syndrome and less commonly by cervical radiculopathy. Some studies have indicated that a postconcussion syndrome can develop from a whiplash injury. Interscapular and low back pain are other frequent complaints. Although most patients recover within 3 months after the accident, persistent neck pain and headaches after 2 years are reported by more than 30% and 10% of patients. Risk factors for a less favorable recovery include older age, the presence of interscapular or upper back pain, occipital headache, multiple symptoms or paresthesias at presentation, reduced range of movement of the cervical spine, the presence of an objective neurologic deficit, preexisting degenerative osteoarthritic changes; and the upper middle occupational category. There is only a minimal association of a poor prognosis with the speed or severity of the collision and the extent of vehicle damage. Whiplash injuries result in long-term disability with upward of 6% of patients not returning to work after 1 year. Although litigation is very common and always raises questions of secondary gain in patients with persistent symptoms, most patients are not cured by a verdict. Acute treatment of neck pain consists of ice for 24 hours followed by heat applications, pain pills, NSAIDs, and muscle relaxants. Trigger point injections can be beneficial in both the acute and the persistent phases. Use of cervical collars should probably be kept to a minimum during the first 2 to 3 weeks after the injury and then avoided. Early passive mobilization and range of motion exercises may accelerate recovery. Physical therapy and transcutaneous nerve stimulators may be helpful in reducing pain and improving movement.(ABSTRACT TRUNCATED AT 400 WORDS)     

Fatigability during volitional walking in incomplete spinal cord injury: cardiorespiratory and motor performance considerations

Fatigability describes the decline in force production(i.e., performance fatigability) and/or changes in sensations regulating performance(i.e., perceived fatigability) during whole-body activity and poses a major challenge to those living with spinal cord injuries(SCI). After SCI, the inability to overcome disruptions to metabolic homeostasis due to cardiorespiratory limitations and physical deconditioning may contribute to increased fatigability severity. The increased susceptibility to fatigability may have implications for motor control strategies and motor learning. Locomotor training approaches designed to reduce fatigability and enhance aerobic capacity in combination with motor learning may be advantageous for promoting functional recovery after SCI. Future research is required to advance the understanding of the relationship between fatigability, cardiorespiratory function and motor performance following SCI.     

The prevalence of motor neurone disease in the Province of Alberta.

Using data from the Alberta Health Care Insurance Plan, the prevalence of motor neurone disease (MND) was estimated for the Province of Alberta, Canada. Between January 1, 1994 and December 31, 1995, 208 cases of MND (125 males, 83 females) were identified from physician billing records giving a period prevalence of 7.38 (8.9 for males, 5.9 for females) per 100,000 population. On prevalence day, July 1, 1995, there were 171 cases (103 males, 68 females) of MND giving a point prevalence estimate of 6.07 (7.3 for males, 4.8 for females) per 100,000 population. Males were more likely to be diagnosed (OR = 1.52, 95% CI 1.1, 2.1) with MND and there was an increased risk of receiving a diagnosis with increasing age (chi 2trend = 281, p < 0.001). The mean age of the cases was 59.2 years (58.5 for males, 60.3 for females) and did not differ significantly between the sexes. Geographically, there was no statistically significant difference in the prevalence across regions of the Province. During the study period, 28% of the cases had died (30% of males, 25% of females). The prevalence of MND in Alberta, is among the highest reported in the literature and requires additional investigation to verify these estimates and identify possible causative factors.     

Incidence of dementia in older adults with intellectual disabilities

Dementia may be more common in older adults with intellectual disability (ID) than in the general population. The increased risk for Alzheimer's disease in people with Down syndrome (DS) is well established, but much less is known about dementia in adults with ID who do not have DS. We estimated incidence rates from a longitudinal study of dementia in older adults with ID without DS and compared them to general population rates. 222 participants with ID without DS aged 60 years and older were followed up an average of 2.9 years later to identify those who had declined in functional or cognitive abilities. Those who screened positive had a comprehensive assessment for dementia, diagnosed using ICD 10 and DSM IV criteria. 134 participants who did not have dementia at initial assessment were alive and interviewed at follow up; 21 (15.7%) were diagnosed with dementia. Overall incidence rate for those aged ≥60 was 54.6/1000 person years (95% CI 34.1–82.3). The highest incidence rate (97.8/1000 person years) was in the age group 70–74. Standardised incidence ratio for those aged ≥65 was 4.98 (95% CI 1.62–11.67). Incidence of dementia in older people with intellectual disabilities are up to five times higher than older adults in the general population. Screening may be useful in this population given the high incident rates, particularly as more effective treatments become available. Studies to explore the underlying aetiological factors for dementia associated with intellectual disability could help to identify novel protective and risk factors.     

Impact of mandatory physician reporting on accident risk in epilepsy

BACKGROUND: In some jurisdictions, physicians are required by law to report patients with seizures to the department of motor vehicles. We assessed the hypothesis that mandatory reporting reduces the risk of automobile accidents in people with epilepsy. METHODS: A retrospective survey of driving and accident rates was done by mailed questionnaire to two groups of subjects with epilepsy in Canada, one living in Ontario where reporting is mandatory and the other in Alberta where it is not. Responses were obtained from a control group without epilepsy for comparison. RESULTS: The epilepsy (n = 425) and control (n = 375) groups were comparable in age and sex. Seventy-three percent of the epilepsy group were or had been licensed drivers compared to 94% of the controls (rr 0.77, 95% CI 0.73-0.83, p < 0.001). Lifetime accident rate of licensed drivers was 58% in epilepsy and 60% in controls (rr 0.99, 95%CI 0.82-1.19, ns) while 9% of the epilepsy group and 9% of the controls had an accident in the previous year (rr 1.00, 95%CI 0.95-1.06, ns). All those with epilepsy in Ontario (n = 202) and Alberta (n = 223), also comparable in age and sex, had equal lifetime accident rates of 45 and 46% (rr 0.99, 95%CI 0.67-1.47, ns) and 1-year rates of 11 and 8% (rr 1.38, 95%CI 0.59-3.27, ns). In Ontario, 20% of drivers were unlicensed compared to 9% in Alberta (rr 2.39, 95%CI 1.17-4.89, p = 0.01) CONCLUSION: Although it is clearly dangerous for many people with ongoing seizures to drive, the findings provide no support for the hypothesis that mandatory reporting of patients by physicians reduces accident risk and suggest that concerns about the impact of epilepsy on driving compared to other medical and nonmedical risk factors may be excessive.
