Injuries and deaths associated with off-road recreational vehicles among children in Manitoba.

Injuries and deaths associated with off-road recreational vehicles are of increasing concern in North America. We reviewed all hospital admissions and deaths attributed to these vehicles in Manitoba from April 1979 to April 1985 among children 16 years of age or younger. Of the 693 hospital admissions and deaths 480 were associated with motorbikes, snowmobiles or all-terrain vehicles (ATVs). The incidence of injuries resulting from snowmobile and dirtbike accidents remained stable over the study period; however, there was an almost exponential increase in the number of admissions because of ATV-related injuries. There were 21 deaths during the study period. Preventive measures through legislation are necessary to reduce the numbers of injuries and deaths; these include mandatory registration, licensing and enhanced safety regulations.     

Epidemiology of Waterskiing Injuries

Coast Guard statistics indicate a national boating fatality rate of 9.6 deaths per 100,000 crafts. In 1977 in California, five fatalities and 70 serious injuries were directly attributable to waterskiing. The four cases reported here include three patients with propeller injuries, including one nearly fatal amputation. In each case basic measures for boating safety were overlooked.     

Injuries from antipersonnel mines: the experience of the International Committee of the Red Cross.

OBJECTIVE--To describe and quantify patterns of injury from antipersonnel mines in terms of distribution of injury, drain on surgical resources, and residual disability. DESIGN--Retrospective analysis. SETTING--Two hospitals for patients injured in war. SUBJECTS--757 patients with injuries from antipersonnel mines. MAIN OUTCOME MEASURES--Distribution and number of injuries; number of blood transfusions; number of operations; disability. RESULTS--Pattern 1 injury results from standing on a buried mine. These patients usually sustain traumatic amputation of the foot or leg; they use most surgical time and blood and invariably require surgical amputation of one or both lower limbs. Pattern 2 injury is a more random collection of penetrating injuries caused by multiple fragments from a mine triggered near the victim. The lower limb is injured but there is less chance of traumatic amputation or subsequent surgical amputation. Injuries to the head, neck, chest, or abdomen are common. Pattern 3 injury results from handling a mine: the victim sustains severe upper limb injuries with associated face injuries. Eye injuries are common in all groups. CONCLUSIONS--Patients who survive standing on a buried mine have greatest disability. Non-combatants are at risk from these weapons; in developing countries their social and economic prospects after recovery from amputation are poor.     

Haemophilus influenzae meningitis in Manitoba and the Keewatin District,NWT: potential for mass vaccination.

A community-based surveillance study of all central nervous system infections was carried out in Manitoba and the Keewatin District, NWT, between Apr. 1, 1981, and Mar. 31, 1984. There were 201 cases of bacterial meningitis in Manitoba over the study period, 81 (40%) caused by Haemophilus influenzae; all but one isolate tested were type b (Hib). There were nine cases of H. influenzae meningitis in the Keewatin District. The overall annual incidence rate of H. influenzae meningitis in Manitoba was 2.5/100,000; for children under 5 years the rate was 32.1/100,000. For the Keewatin District the corresponding rates were 69.6/100,000 and 530/100,000. A total of 85% and 100% of the cases of H. influenzae meningitis occurred by 24 months of age in Manitoba and the Keewatin District respectively. The age at onset was earlier in native Indian children (22 cases) and Inuit children (9 cases) than in non-native children (59 cases) (p less than 0.005); thus, vaccine prevention of Hib meningitis will likely be more difficult in native Indian and Métis children. Without evaluating the increased potential of H. influenzae vaccines to prevent nonmeningitic forms of disease, we concluded that mass childhood vaccination with polyribosylribitolphosphate (PRP) vaccine is not warranted in Manitoba or the Keewatin District. Immunogenicity studies suggest that administration of conjugated Hib vaccines such as PRP-D in infancy may prevent approximately one-third to two-thirds of cases of H. influenzae meningitis; these vaccines warrant consideration for use in mass childhood vaccination programs.

目的:探讨MESS评分在治疗肢体严重软组织损伤中的应用价值。方法:回顾性分析我科2010年8月至2014年5月收治的50例肢体严重软组织损伤患者的临床资料,其中男34例,女16例,年龄23~53岁,平均38岁。所有患者入院时均采用MESS评分表进行评分,根据病情给予清创、保肢或截肢以及创面修复等系列治疗,并随访3个月~3年。按照治疗结果将患者分为保肢组、Ⅰ期截肢组和Ⅱ期截肢组,分析和比较三组的MESS分值、住院天数、手术次数、并发症的发生率及患者满意率。结果:保肢组32例,MESS评分6-11分,平均8.63±1.26分。截肢组18例,MESS评分11-14分,其中Ⅰ期截肢组10例,平均12.60±0.97分;Ⅱ期截肢组8例,平均12.88±0.83分。保肢组患者的MESS分值显著低于Ⅰ期截肢组(P0.05)和Ⅱ期截肢组(P0.05)。此外,保肢组患者满意率显著高于Ⅰ期截肢组(P0.05)和Ⅱ期截肢组(P0.05)。而Ⅰ期截肢组的住院时间、手术次数和并发症发生率均短于或少于Ⅱ期截肢组,患者满意率高于Ⅱ期截肢组(P0.05)。结论:对于MESS评分11分的患者行保肢治疗可收到满意的效果,而对MESS评分11分的患者,采取Ⅰ期截肢的治疗效果优于Ⅱ期截肢。     

Mobile hearing program in central rural Manitoba.

A mobile hearing program was developed to detect and alleviate deafness and rehabilitate deaf individuals in rural Manitoba. The first project was established in central Manitoba in December 1973 for children, whose school performance can be affected by minimal hearing loss. Volunteers from the community, trained by an audiologist, conduct screening procedures, and children with possible hearing impairment receive audiologic and otolaryngologic assessment. Close clinical liaison between audiologist and otologist is important.     

Salvage after severe lower-extremity trauma: are the outcomes worth the means?

Advances in reconstructive surgery have allowed for impressive salvage after severe lower-extremity trauma but not without complications when compared with immediate below-knee amputation. Several amputation index scores have been developed to help predict successful salvage as defined by a viable rather than a functional extremity. The purpose of this study was to evaluate retrospectively the predictive value of the amputation index scores and to assess prospectively overall health status and specific dysfunction in successful limb salvage and primary and secondary amputation by administering standardized generic and specific outcomes questionnaires (Medical Outcomes Study 36-Item Short-Form Health Survey, Western Ontario and MacMaster Universities Osteoarthritis Index). A retrospective chart review identified 55 severe lower-extremity injuries (Gustilo Type IIIB and IIIC) over a 12-year period (1984 to 1996). Forty-six severe open tibial fractures in 45 patients underwent attempted salvage. All required soft-tissue coverage by either local or free flap or vascular repair for leg salvage. The attempted-salvage group was subdivided into successful salvage and secondary amputation. The other nine patients underwent a primary amputation. There were no statistically significant differences in terms of patient demographics or other injuries (Injury Severity Score) in the three groups. Forty-eight of 54 patients with an average 5-year follow-up completed a validated generic and specific outcomes health questionnaire. In the attempted-salvage group, 89 percent of patients had a successful salvage and 11 percent came to a secondary amputation. The amputation index scores correctly predicted an amputation in 32 percent of patients. The magnitude of the amputation index scores did not correlate with the physical outcomes scores and were not found to add any significant value of information to the surgeon's decision making. Patients undergoing primary and secondary amputation had a worse physical outcomes score (28 versus 38) than successful salvage (p < 0.007). Even so, the SF-36 (physical component score) outcomes score for this group of injured extremities, regardless as to whether salvaged or amputated, was as low as or lower than that of many serious medical illnesses, suggesting that severe lower-extremity trauma impairs health as much as or more than being seriously ill. The mental component score in this group was comparable to that of a healthy population (49 versus 50), which implies the disability is primarily physical rather than psychological. Ninety-two percent of patients preferred their salvaged leg to an amputation at any stage of their injury, and none would have preferred a primary amputation.     

Bicycle-related injuries: a survey in a pediatric emergency department.

The number of bicycle-related injuries has risen significantly with the increased popularity of bicycle riding in Canada. The risk of injury is highest among children. To assess the magnitude of the problem and to identify the contributing factors we used a questionnaire, injury reports and patient charts to survey bicycle-related injuries among children brought to the emergency department of the Children''s Hospital of Eastern Ontario, Ottawa, between May 1 and Sept. 30, 1988. The questionnaire was completed for 517 (91%) of the 568 children; 70% were boys, and the mean age was 9.4 years. Only 2% of the patients had been wearing a helmet at the time of injury, although 13% claimed to own one for cycling. Over 60% of the accidents were attributable to carelessness or poor bicycle control; mechanical failure and environmental hazards were minor factors. Over 80% of the injuries occurred within a kilometre of the child''s home. Of the 97 children admitted to hospital 49% had head and skull injuries and 40% had limb fractures. Bicycle-related injuries represented 14.8% of all nonwinter (Apr. 1 to Oct. 31) trauma admissions among children 5 years or older. Our results further document bicycle-related injuries as an important childhood problem and underscore the need for improved safety measures.     

Preventing injuries in children: cluster randomised controlled trial in primary care

ObjectiveTo assess the effectiveness of safety advice at child health surveillance consultations, provision of low cost safety equipment to families receiving means tested state benefits, home safety checks, and first aid training on frequency and severity of unintentional injuries in children at home.DesignCluster randomised controlled trial.Setting36 general practices in Nottingham.SubjectsAll children aged 3-12 months registered with participating practices.InterventionsA package of safety advice at child health surveillance consultations at 6-9, 12-15, and 18-24 months; provision of low cost safety equipment to families on means tested state benefits; and home safety checks and first aid training by health visitors.ResultsAt baseline, both groups had similar risk factors for injury, sociodemographic characteristics, safety practices, possession and use of safety equipment, knowledge and confidence in dealing with first aid, and perceptions of risk. No significant difference was found in frequency of at least one medically attended injury (odds ratio 0.97, 95% confidence interval 0.72 to 1.30), at least one attendance at an accident and emergency department for injury (1.02, 0.76 to 1.37), at least one primary care attendance for injury (0.75, 0.48 to 1.17), or at least one hospital admission for injury (0.69, 0.42 to 1.12). No significant difference in the secondary outcome measures was found between the intervention and control groups. ConclusionsThe intervention package was not effective in reducing the frequency of minor unintentional injuries in children at home, and larger trials are required to assess the effect on more severe injuries.

Key messages

• A package of activities for preventing injuries, as suggested by the Health of the Nation, delivered to families with children aged under 3 in primary care did not reduce the frequency of minor injuries
• The findings were consistent with a reduction in the frequency of more severe injuries, and larger primary care based studies are required to test this hypothesis
• The effectiveness of each of the interventions, delivered singly, is not known

     

Lacerations from glass in childhood.

A study of 62 glass injuries to children serious enough to warrant admission to hospital showed that 30 were due to architectural glass in doors or windows and 26 of these occurred in houses. Glass bottles caused 12 injuries. Architectural glass produced more serious injuries affecting major arteries, nerves and tendons, and internal viscera. In view of the frequency and severity of architectural glass injuries in houses, safety glass in recommended for all glass doors, French windows, patio doors, and the lower parts of windows.

A Pilot Study to Evaluate an Elementary School-Based Dog Bite Prevention Program

ABSTRACT

The primary objective of this program evaluation was to determine if a school-based education program is an effective means of informing elementary school-aged children enrolled in second through fourth grades about dog bite safety—the awareness of proper behavior when in the company of dogs to prevent bites, injuries, or fatalities. The pilot program, featuring written materials and a video, was developed to teach dog bite safety, and questionnaires were designed to assess the program. Students (n=486) from seven schools from Montgomery and Prince George's Counties in Maryland, USA participated. Pre- and post-program questionnaires assessed students' interactions, encounters, and relationships with dogs, as well as use of program materials, and changes in understanding about dog behavior, body language, and bite avoidance. The program results appeared to be highly effective in helping children understand how to prevent or avoid potentially threatening situations involving dogs. The program was most effective at teaching children that: (1) neighborhood and family dogs are most likely to cause dog bite-related injuries, (2) they should never run away from a dog, and (3) they should never touch a dog that is sleeping or eating. For most groups, there was also an increased level of recognition of canine body language. Almost half of the participants indicated that they had been bitten in the past, and over 80% knew the attacking dog. Finally, the findings suggest that an age-appropriate dog bite safety program delivered in an elementary school setting can be effective in producing awareness about preventing dog bite-related injuries. Future investigations should concentrate on monitoring actual changes in child behavior.     

Where Manitoba children obtain their cigarettes.

People who start to smoke as children put themselves at greater risk of dying prematurely or being disabled by tobacco-induced disease. One solution is to restrict children''s access to cigarettes, thereby reducing consumption of the product and, ultimately, damage to health. This study found that in 1985 the majority of Manitoba public school children 8 to 15 years of age who smoked "regularly" (defined as usually every day) obtained their cigarettes from stores. This source could be reduced, if not eliminated, were a federal regulation passed in 1908 enforced. Under Canada''s Tobacco Restraint Act it is illegal for merchants to sell tobacco to anyone under the age of 16 years. By implementing this existing law, authorities would not only be keeping the profit from almost a million dollars in cigarette sales in Manitoba alone out of tobacco company coffers but also be having an impact on the leading cause of preventable premature death and disability in Canada.     

High pressure paint gun injuries.

Despite their use for the past 20 years the dangers of injuries from high pressure paint guns are not widely known. Two cases treated incorrectly through ignorance in our casualty department resulted in amputation of digits. Paint solvents are far moe damaging than paint of grease injection. All cases should be treated urgently by an experienced surgeon as fairly extensive surgery may be needed.     

Spin Dryer Injuries

Three children were injured by putting their arms into spin dryers. In each case the injuries were severe. Though not common, these accidents should be preventable. Warning notices are useless for toddlers, and a built-in safety mechanism seems the only certain means of stopping such accidents.     

Wound infection by multiresistant Staphylococcus sciuri identified by molecular methods

We describe a case of wound infection by multidrug-resistant Staphylococcus sciuri in a patient admitted to hospital for injuries in Agreste Alagoas, Brazil, identified through broad-spectrum PCR and sequencing of 16S rDNA gene. Due to its high resistance profile, the infection was characterized as methicillin-resistant Staphylococcus presenting sensitive only to vancomycin and chloramphenicol. The injury resulting from trauma associated with infection resulted in amputation of the infected limb.     

Minimizing impairment in laborers with finger losses distal to the proximal interphalangeal joint by second toe transfer

Traditionally, toe-to-hand transfers have been reserved for thumb amputations or for use after severe mutilating injuries. The authors report their experience with the use of second toe-for-finger amputations with preserved or reconstructible proximal interphalangeal joints in manual workers. The aim of the procedure was to reduce impairment and to upgrade the hand from a functional and cosmetic standpoint. Fifteen second-toe wrap-around or variations were carried out on 11 adults (18 to 41 years old). Four patients with two or more finger amputations received two sequential second toes; four patients with two finger amputations received one toe; and each of three patients with single-digit amputation received a single toe. All but one amputation were performed less than 3 weeks after the accident. All toes survived. Range of motion at the native proximal interphalangeal joint was more than 90 percent in all patients but one; however, it was minimal at the transplanted joints. Patient satisfaction was high from a cosmetic and functional standpoint. Ten of 11 laborers resumed their previous activity. On the basis of this experience, a classification with aesthetic and functional implications is proposed to help in the decision-making process when dealing with multidigital injuries. It is concluded that second-toe transfer is an excellent choice for finger amputation distal to the proximal interphalangeal joint in laborers. Its prime indication is for amputations of two fingers where at least one toe should be transferred, as required, to achieve an "acceptable hand" (three-fingered hand). Early transfer allows salvage of critical structures from the damaged finger, such as joints, tendons, and bone, that otherwise would be lost. Early transplantation is highly recommended.     

The Management of Lower Extremity Multilevel Arterial Injuries: A 10-Year Experience

Background

Limb amputation due to lower extremity arterial injury is not uncommon and multilevel arterial injury is even more limb-threatening and easily missed with potentially devastating consequences. There is limited information on multilevel arterial injuries.

Purpose

We undertook a review of our experience to gain insight on multilevel arterial injury patterns associated with lower extremity trauma and to analyze the results of management of such injuries with a special focus on the influence of initial diagnosis on limb salvage.

Patients and Methods

Between August 2002 and September 2012, 38 patients with lower extremity multilevel arterial injuries were reviewed, retrospectively. The injury patterns and amputation rates associated with initial diagnosis or misdiagnosis were analyzed.

Results

According to their injury levels, three multilevel arterial injury patterns were seen in this series: arterial injuries with the involvement of femoral artery and popliteal artery (pattern A), femoral artery and anterior or (and) posterior artery (pattern B), and popliteal artery and anterior or (and) posterior artery (pattern C). The general missed diagnosis rate was 31.6%. Pattern B had a much higher missed diagnosis rate than the other two patterns. The missed diagnosis rate was significantly correlated with the amputation rates (Odds Ratio =10.7, 95% CI: 2.04-56.61). The definite diagnosis rate was only 14.8% using duplex ultrasonography examination.

Conclusions

Diagnosis of pattern B injury is more prone to be missed. DUS has low specificity in the detection of multilevel arterial injuries. Aggressive intraoperative exploration is considered to be valuable in the definitive diagnosis of highly suspected cases when other diagnostic tools are unavailable.     

Traction avulsion amputation of the major upper limb: a proposed new classification, guidelines for acute management, and strategies for secondary reconstruction.

Major replantation of a traction avulsion amputation is undertaken with the goal of not only the reestablishment of circulation, but also functional outcome. This type of amputation is characterized by different levels of soft-tissue divisions involving crushing, traction, and avulsion injuries to various structures. Between 1985 and 1998, 27 cases were referred for secondary reconstruction following amputation of the upper extremity involving both arm and forearm. Replantation was performed by at least 12 qualified plastic surgeons using different approaches and management, resulting in different outcomes. Initial replantation management significantly affects the later reconstruction. For comparing studies and prognostic implications, the authors propose a new classification according to the level of injury to muscles and innervated nerves: type I, amputation at or close to the musculotendinous aponeurosis with muscles remaining essentially intact; type II, amputation within the muscle bellies but with the proximal muscles still innervated; type III, amputation involving the motor nerve or neuromuscular junction, thereby causing total loss of muscle function; and type IV, amputation through the joint; i.e., disarticulation of the elbow or shoulder joint. Some patients required further reconstruction for functional restoration after replantation, but some did not. Through this retrospective study based on the proposed classification system, prospective guidelines for the management of different types of traction avulsion amputation are provided, including the value of replantation, length of bone shortening, primary or delayed muscle or nerve repair, necessity of fasciotomy, timing for using free tissue transfer for wound coverage, and the role of functioning free muscle transplantation for late reconstruction. The final functional outcome can also be anticipated prospectively through this classification system.
