Differences in illness perception about hand injury may partly explain the variation in health behaviours such as adherence to post-operative therapy, coping strategy, emotional response and eventual clinical outcome. This study examined the illness perception of patients with hand injuries in the acute trauma setting.

Complex injuries of the hand remain a therapeutic challenge for surgeons. We present the case of a male who suffered a devastating injury of the hand caused by a conveyor belt. The patient developed a progressive Absidia corymbifera infection of the affected soft tissues. Initial treatments with serial surgical debridement and topical and intravenous itraconazole were unsuccessful in eliminating the infection. We decided to use maggot debridement therapy in a new special design to debride all necrotic, devitalized tissue and preserve only healthy tissue and functioning structures. This maneuverer followed by negative pressure therapy allowed progressive healing. In such complex hand injuries, maggot debridement combined with negative pressure therapy could be considered to achieve effective and considerable results, although future functional morbidity may occur (Fig. 4, Ref. 18).

Full Text Available Background High-pressure injections into the hand, burden devastating and permanent functional impairments. Many materials including paint, paint thinner, gasoline, oil and grease are reported as the causative agents. These injuries need multiple procedures and reconstructions most of the time and 40% of the injuries may end with amputation of the injured part. Objectives The aim of this study was to report the treatment outcomes and methods of treatments of patients with high-pressure injection injuries of the hand. Methods We retrospectively reviewed the medical records, imaging files and demographic data of patients, who were treated at our center due to the high-pressure injuries to their hands. We recorded the kind of the injected materials, time to the first treatment procedure, times of operation, and methods of their treatments. The outcomes of the injuries as well as the deficiency of the digital joints motion were also reported. Results Nine cases with high-pressure injury of the hand were enrolled in this study. All patients were male with mean age of 26.88 ± 7.52. Mean follow-up time was 28.55 ± 12.49 months. The dominant hand was the right side in seven patients and left in two patients. Injury was in the left hand of seven patients and right hand of two patients. Index finger was the most common involved part (five cases followed by the thumb (two cases. Injected material was grease in seven cases, water-base paint and water, each in one case.Mean time delay to the first treatment procedure was 29.16 ± 25.66 hours for seven patients. This was exceptionally long for two patients (seven days and 24 months. Type of treatment was debridement and skin graft for three cases, debridement and cross finger flap for two cases, debridement for two cases and nerve graft for one case. Amputation of the necrotic digit was performed for one case. Mean hospitalization time was 8.33 ± 3.64 days for all patients.Mean total active range of motion

Previous studies have shown that young men have the highest frequency of occupational hand injuries. This study investigated their incidence and severity in relation to age and sex. For occupational hand injuries in general the estimated incidence rate was 17.1 per 1,000 person years. The incidence...... was found to be higher among men than women in all age groups below 60 years. The incidence for minor injuries declines with increasing age, but the rates for significant injuries are independent of age. The higher incidence rate for minor injuries among young patients could be real, but it could also...

Although hand injuries due to kite strings seem to be trivial, these injuries could be serious enough to lose the function of hand. This case series in the division of Plastic and Reconstructive Surgery of our institution from August 2014 to January 2016 evaluated the clinic-etiological profile, severity and management of hand injuries due to kite strings assessed clinically and radiologically. Eleven patients reported kite related injuries during two years, and 5 presented during 17 months. Of 11 patients, 8 were male and 3 were female with a M:F ratio of 2.66:1. The majority of patients presented with the mean age of 19.9±4.27 years. Eight patients presented acutely to the emergency while 3 believed the injury to be trivial and had delayed presentation. Injuries in the right hand were 8 and 3 in the left hand. Seven patients had injuries in zone II of the hand while 4 presented with zone III injuries. Total number of injured digits was 14 (1.4±1.11), total number of injured tendons was 26 (2.36±2.18), only one patient had nerve injury (mean=0.09), and no patient had any major vessel injury. So strict attention to safety measures and parental/guardian supervision while flying kites can avoid many preventable injuries to life and limb and also let the sport be an enjoyable and safe.

[Prevention of Occupational Injuries Related to Hands: Calculation of Subsequent Injury Costs for the Austrian Social Occupational Insurance Institution (AUVA)].

Occupational injuries cause short-term, direct costs as well as long-term follow-up costs over the lifetime of the casualties. Due to shrinking budgets accident insurance companies focus on cost reduction programmes and prevention measures. For this reason, a decision support system for consequential cost calculation of occupational injuries was developed for the main Austrian social occupational insurance institution (AUVA) during three projects. This so-called cost calculation tool combines the traditional instruments of accounting with quantitative methods such as micro-simulation. The cost data are derived from AUVA-internal as well as external economic data sources. Based on direct and indirect costs, the subsequent occupational accident costs from the time of an accident and, if applicable, beyond the death of the individual casualty are predicted for the AUVA, the companies in which the casualties are working, and the other economic sectors. By using this cost calculation tool, the AUVA classifies risk groups and derives related prevention campaigns. In the past, the AUVA concentrated on falling, accidents at construction sites and in agriculture/forestry, as well as commuting accidents. Currently, among others, a focus on hand injuries is given and first prevention programmes have been initiated. Hand injuries represent about 38% of all casualties with average costs of about 7,851 Euro/case. Main causes of these accidents are cutting injuries in production, agriculture, and forestry. Beside a low, but costly, number of amputations with average costs of more than 100,000 Euro/case, bone fractures and strains burden the AUVA-budget with about 17,500 and 10,500 € per case, respectively. Decision support systems such as this cost calculation tool represent necessary instruments to identify risk groups and their injured body parts, causes of accidents, and economic activities, which highly burden the budget of an injury company, and help derive

Injuries caused by firewood splitting machines.

Hellstrand, P H

1989-01-01

The aim of this paper is to present the types of injury caused by firewood splitting machines and also to elucidate the accident mechanism. The study is based on 15 cases. The machine has a rotating spiral cone, and usually the victims' gloved fingertips were caught by the point of the cone. This led to either amputations, usually of radial fingers and/or penetrating wounds through the middle of the hand. In most cases the accidents could not be blamed on bad working techniques. The study of the mechanisms of injury points to insufficient protective devices in a machine construction which has a potentially dangerous working principle.

Treatment of disorders caused by radiation injury in the hand and fingers

Watanabe, Yoshihiro

1976-01-01

In this paper, a report was made on 8 cases of disorders caused by radiation injury in the hand and fingers and on those treatment. In 5 cases of them, keratosis of the skin (an average of 10 years after the initial fluoloscopy) and ulceration (an average of 17 years after the initial one) due to x-ray fluoloscopy were noted. Cancer was found in 2 cases of them and precancer in the other 2 cases of them. The lesions continued to develop after radiation was stopped. In 2 cases which had received x-ray irradiation for the treatment, one case developed erosion one year after the institution of the therapy and the other had the similar change two years after that. In both of the cases, precancerous state was noticed. In the last case, erosion appeared 6 years after the patient had dealt with radium in giving treatment. Ulceration appeared 16 years after the patient had dealt with radium in giving treatment. In 4 cases in which lesions had been restricted in the corium layer, the treatment was the resection of the skin and dermatoplasty, and thus the function of the fingers recovered. In the other 4 cases in which the pathological changes had spreaded over the deeper layers, the fingers were severed. (Serizawa, K.)

Tag rugby is one of the fastest growing sports in Ireland. It is a soft-contact team game that is loosely based on the rugby league format except players try to remove Velcro tags from their opponents' shorts rather than engage in a typical rugby tackle. The purpose of this study was to examine all tag rugby associated hand injuries over a five-year period in three large tertiary referral hospitals in Ireland. Using the patient corresponding system, 228 patients with hand injury related tag rugby injuries were observed from 2010 to 2015. There were 138 males and 90 females in the study and over 40% of patients required surgery. Most of the patients were young professionals with an average age of 30. Twenty-five patients worked in the financial services whilst there were 23 teachers. Fractures accounted for 124 of the 228 injuries and mallet injuries accounted for 53. Eighty percent of all injuries occurred during the tackle. The mean number of days missed from work was 9.1±13.8 days. These injuries resulted in an average of seven hospital appointments per patient. Considering it is a soft-contact sport, it is surprising the number of hand injuries that we have observed. Although safety measures have been introduced to decrease the number of hand injuries in recent years, there is a need for further improvements. Better player education about seeking prompt medical attention once an injury occurs, coupled with longer shorts worn by players may improve measures for the sport. Copyright © 2016.

Ninety-one (85.04% patients injured within one year of employment and 57(53.27% patients were not satisfied with instructions and orientation before starting their job. Hand injury is one of the most common injuries in the oil industry and overtime work further increases incidence of this injury.

The Avocado Hand

LENUS (Irish Health Repository)

Rahmani, G

2017-11-01

Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut\\/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non-dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the “avocado hand”. We present a case of a 32-year-old woman who sustained a significant hand injury while preparing an avocado. She required exploration and repair of a digital nerve under regional anaesthesia and has since made a full recovery.

Systematic review. Traumatic hand injuries are frequent cause of work related injuries and can result in prolonged durations of time loss from work. To systematically review available evidence to determine which prognostic factors predict return-to-work (RTW) following work-related traumatic hand injuries. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO from 1980 to September 2013 and reference lists of articles. Studies investigating any prognostic factors of RTW after traumatic hand injury were included. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Identified factors were grouped into conceptual prognostic factor categories. We assessed 8 studies, which addressed 11 potential prognostic factors (i.e., sociodemographic factors, occupation, work compensation status, treatment related factors, impairment severity, location of injury, etc.). The quality of the studies was low to moderate. Across all included studies, RTW (original or modified work) occurred in over 60% of individuals by 6 months. There was consistent low-moderate quality evidence that individuals with more severe impairments and lower pre-injury income were less likely to RTW, and low-moderate quality evidence that age, gender and level of education had no impact on RTW. Evidence on other commonly cited prognostic factors were limited in the literature. Impairment severity and lower pre-injury income showed a consistent association with RTW following occupational hand injury, while other factors demonstrated no or variable effects across studies. Additional high-quality studies are warranted toward improving our understanding of the complex factors that mediate RTW following a traumatic work-related hand injury. 2a.

Overall, 41% of all work-related accidents lead to a hand injury. In the younger generation, the incidence rate even rises to 50%. In Austria, these accidents result in approximately half a million sick leave days per annum, an average of 12.5 days per accident. In comparison, leisure-time hand injuries show a significantly higher accident rate: 60% of hand injuries occur during leisure time. Far fewer safety measures are taken and a lack of adequate training and a disregard for safety recommendations are observed.This large number of hand injuries led to the launch of a campaign in Austria in 2014-2015 called "Hände gut - Alles Gut", (Hands well - all's well). This campaign was aimed at reducing the costs, a sum of 309 million Euros, incurred solely from work-related hand accidents, by at least 5-10%.These exorbitantly high costs are not only due to severe hand trauma, most result from a multitude of slight and superficial wounds.

To report the return to play from metacarpal fractures, phalangeal fractures, and thumb ligament tears in National Basketball Association (NBA) players over a 5-year period. Descriptive epidemiology study. The NBA transaction report was analyzed from January 2009 to May 2014. Players were identified if they were added to the inactive list (IL), missed games due to their injury, or underwent surgery as a result of hand injury. Number of games missed due to injury, days spent on the IL, and age at injury were calculated by injury type and location. One hundred thirty-seven injuries were identified: 39 injuries to the hand and 98 injuries to the finger. Three major injury patterns were identified and analyzed: metacarpal fractures (n = 26), phalangeal fractures (n = 33), and thumb ligament tears (n = 9). The type of injury sustained affected return to play ( P basketball players can lead to prolonged periods of time away from competition, especially after surgery. This study provides guidelines on expected return to play in the NBA after these common hand injuries.

Studies have been conducted at both area and individual levels, the bulk of which deal with road traffic, burn, and fall injuries. As a whole and for each injury cause separately, their results support the notion that low socioeconomic status is greatly detrimental to child safety but not in all instances and settings. In light of variations between causes and, within causes, between settings and countries, it is emphasized that the prevention of inequities in child safety requires not only that proximal risk factors of injuries be tackled but also remote and fundamental ones inherent to poverty.

2013-12-01

Recreational mountain biking continues to increase in popularity and is a significant source of traumatic injury, including injuries to the hand and wrist. A prospective survey of all hand and wrist injuries sustained while participating in recreational mountain biking presenting to the emergency department at the Municipality of Whistler and the District of Squamish was conducted over a 12-month consecutive period. An analysis of 765 unique emergency department visits with 1,079 distinct injuries was performed. Of these injuries, 511 were sustained to the upper limb. Injury to the metacarpal and metacarpal phalangeal joints was the most common hand injury (52) followed by proximal phalanx and proximal interphalangeal joint (20). Mountain biking is a frequent source of a variety of upper limb trauma, and preventative efforts are necessary to minimize the burden of these injuries.

The hands of "blast" resulting from the handling of unstable explosives. Their repercussion is functional and vital in trauma patients. The authors report their experience of care from the hands of blast in precarious health situation. Between 2001 and 2012, 33 hand blasts were supported in 30 injured civilians and military, received emergency, during and after armed conflict. Two women (6.7%) and 28 men (93.3%) were received, including four teenagers (13.3%) and 26 adults (86.7%). During the war, 15 officers weapon (50%) and three civilians (10%) underwent surgery, or 60% of hand injuries. In peacetime, civilians were mostly operated in 33.3% of cases, against 6.7% of cases of agents' weapon. Nineteen hands blast (57.6%) were observed during the war and 14 in peacetime, or 42.4% of cases. The average age was 25.2 years, with extremes of 12 and 50 years. Thirteen left hands (39.4%) and 20 right hands (60.6%) were operated. The lesion concerned all the anatomical structures of the hand. It was unilateral in 27 cases (81.9%) and bilateral in three cases (9.1%). Three types of hand trauma were observed and were as follows: trauma patients with injuries of the hand (18.2%), trauma of severe and isolated proximal hand or finger amputations (75.7%), and trauma of the hand without apparent seriousness (6.1%). The associated lesion was eye (one case), chest (one case), abdominal (five cases). Debridement was performed immediate emergency (93.9%) and delayed (6.1%). The treatment was surgical hemostasis, made mainly of amputations (69.7%) and regularization of digital stumps (12.1%). The repair was performed in 18.2% of cases. One death has been reported in a polytrauma patient with chest blast. Blast injuries of the hand are common in times of war in armed agents. The young people, manual workers and children are paying a heavy price in peacetime. As land mines which affect feet, instable hand grenades are left exposed in nature.

Full Text Available Abstract Background Cold sensitivity is a common and disabling complaint following hand injuries. The main purpose of this study was to describe self-reported consequences of cold sensitivity and the association with disability and health-related quality of life in patients with hand injuries or hand-arm vibration syndrome (HAVS and in normal subjects. Methods Responses to the Cold Intolerance Symptom Severity (CISS questionnaire, Potential Work Exposure Scale (PWES, Disability of the Arm, Shoulder and Hand (DASH and Short-Form 36 questionnaire (SF-36 were investigated in normal subjects (n = 94, hand injured patients (amputation and nerve injuries, n = 88 and patients with HAVS (n = 30. The results are presented as median (range, percent and mean deviation from norms. The Kruskal Wallis Test or Mann-Whitney U-Test were used to identify significant differences between multiple groups or subgroups. The Spearman rank correlation was used to study the relationship between cold sensitivity and disability. Results Abnormal cold sensitivity (CISS score > 50 was seen in 75% and 45% of patients with HAVS and a traumatic hand injury, respectively. Patients were significantly more exposed to cold in their work environment than the normal population, with a consequently negative effect on work ability due to cold sensitivity. Patients with abnormal cold sensitivity were more seriously disabled and had a poorer health-related quality of life than patients with normal cold sensitivity [higher DASH scores and e.g. significantly larger mean deviation from norms in the subscales Role Physical and Bodily Pain (SF-36]. Conclusion Severe and abnormal cold sensitivity may have a profound impact on work capacity, leisure, disability and health-related quality of life. It is frequently seen in patients with traumatic hand injuries and particularly apparent in patients with HAVS.

2016-01-01

The purpose of this study was to describe the role of public exercise equipment in pediatric hand traumas as a preventable etiological factor. Pediatric patients with hand injuries referred from the emergency department were evaluated retrospectively. Age and gender of the patients, timing, etiology, mechanism of hand trauma, localization of the injury, diagnoses of the patients, and hospitalization rates were reviewed. Amongst the 310 pediatric patients evaluated, 31 patients (10%) experienced injury related to public exercise equipment. Within this group of patients, most were between 5 to 9 years of age, and all injuries were blunt and crush type. Lacerations and fractures were the main diagnoses. Complex injuries that required inpatient care were reported in 19.3% of the patients. Public exercise equipment-related injuries are increasingly prevalent in pediatric hand traumas. Preventive actions such as shielding the moving parts should be taken to reduce these rates.

Full Text Available Background: Currently, analyzing the economic losses caused by health problems in population is of particular importance since it stipulates calculations of the volumes invested in healthcare systems in order to improve population’s health. Objective: The aim of our study was to find out economic losses caused by traumatic brain injury (TBI in children. Methods: The given work has utilized governmental statistical reports for Russia, for federal regions as well as for individual subjects. Direct medical expenses (medical services and indirect expenses (losses due to a temporary disability of parents having a sick child were calculated both in general and per patient. Results: Among all the direct medical costs of treatment of children with TBI inpatient care costs account for 85%. In the Central and Volga Federal District accounted for half of nationwide spending in general, brain injury and to provide certain kinds of healthcare. The structure of Russian costs as a result of the incidence of TBI children Moscow accounts for 20%. In Moscow, the cost of treating cases of traumatic brain injury in children is 3.2 times higher than the average for Russia. The resulting calculations of the value of health care costs attributable to a case of child head injury, behind the cost of treatment of the case of a child with head trauma, calculated according to the standards of Russia and the territories. This difference in the whole RF is 23%. Conclusion: The obtained findings have shown that in 2010 in Russia the magnitude of losses caused by TBI incidence in children amounted to 3 billion roubles or 0.008% of the gross product 1.2 billion roubles of which were direct expenses. However, this figure is considerably lower of the real amount; it becomes evident after the analysis of direct medical expenses per one case of pediatric TBI. Our calculations have shown that in Russia and in its regions the amount of expenses per one TBI patient is a quarter less

2014-01-01

The aim of this research study was to gain an understanding of how rural and remote residents in North Queensland, Australia, engaged in work, activities of daily living tasks and social activities following a traumatic hand injury. Findings from a previous retrospective survey with these participants revealed that patients experienced difficulties such as pain for many years after their injury; however, because of the survey methodology, the voices of participants were not heard. This study contributes to a larger project that seeks to propose a model of service delivery to rural and remote residents who have sustained a traumatic injury. Utilising an interpretive phenomenological research design, data were gathered through in-depth, semistructured interviews. Fifteen participants were recruited into this study and questions were designed to explore the experience of having a traumatic hand injury in rural and remote areas of North Queensland. The thematic analysis indicated five major themes: injury and impairment, pain, occupation and activity, and resilience. Participants reported that having a hand injury often caused further injury due to the impairment. The pain experienced could be 'all consuming' yet participants reported 'pushing through' this pain to complete daily tasks. Participants reported that they would 'go mad' if they did not work and highlighted the importance of activity in their recovery. Participants felt grateful at having their hand and thought towards the future. Being self-reliant was important but they were willing to accept support from others when needed. Incorporating activity and occupation in rehabilitation programs as opposed to focusing on strict protocols is an important consideration in the recovery process of rural and remote residents. In particular, engaging in activity and occupation was an important part of managing the pain associated with the hand trauma. This research also found that participants demonstrated resilient

Clinicians hand position and advised pushing techniques may impact on rates of perineal injury. To assess the association of four techniques used in management of second stage with risk of moderate and severe perineal injury. Retrospective cross-sectional study. A metropolitan maternity hospital and a private maternity hospital in Brisbane, Australia. Term women with singleton, cephalic presentation experiencing a non-operative vaginal birth from January 2011 to December 2016. The research sites perinatal database recorded data on clinicians approach to instructing women during second stage and hand position at birth. Women were identified from matching the inclusion criteria (n = 26,393) then grouped based on combinations of hands-on, hand- poised, directed and undirected pushing. The associations with perineal injury were estimated using odds ratios obtained by multivariate analysis. Primary outcomes were the risk of moderate and severe perineal injury. The significance was set at 0.001. In Nulliparous women there was no difference in the risk of moderate or severe perineal injury between the different techniques. In multiparous women the use of a hands-on/directed approach was associated with a significant increase in the risk of moderate (AOR 1.18, 95% CI 1.10-1.27, p < 0.001) and severe perineal injury (AOR 1.50, 95% CI 1.20-1.88, p < 0.001) compared to hands-poised/undirected. A hands poised/undirected approach could be utilised in strategies for the prevention of moderate and severe perineal injury. Copyright © 2018 Elsevier Ltd. All rights reserved.

High-pressure injection injuries of the hand have a reputation for being dangerous for individual fingers and even for whole hand. Usually appearing innocuous at presentation because of small puncture entry wound, these injuries result in severe damage of most internal structures in finger and hand due to extensive penetration of injected substance. This paper reviews the outcome of the treatment of such injuries in 10 patients: 9 sustained injection of toxic paint, and one lead shot. All the patients were operated on: eight a few hours after injury and two with 3 days delay. The surgical technique included wide exposure from site of injection up to the farthest place in which foreign substance was seen. Thorough debridment of injected material and contaminated tissue was performed with careful preservation of neurovascular structures and tendons. Wounds were not closed, but managed by open technique. In all patients wounds healed well: in 3 by secondary intention, in 6 by delayed closure and 2 were covered by skin grafts. No amputation was performed. Final results were assessed form 1.5 to 3.5 years after initial injury (mean at 2.5 years). Two patients complained of moderate pain related to the weather, five of cold intolerance and two of impaired sensation on fingertips. Active range of motion of affected fingers was in whole group from 90% to 104% (mean 97%) of the range of motion of unaffected fingers from the other side. Range of motion of the wrist (2 patients) was 76% and 117% of range of motion of the other side. Pinch grip strength was from 81% to 116% (mean 99%), and global grip strength from 77% to 119% (mean 97%) of the other side. All patients went back to their previous jobs and periods of sick leave were from 2 weeks to 6 months (mean 3 mo). Excellent results achieved in this study--full functional recovery in 9 of 10 patients confirm the effectiveness of aggressive treatment by open wound technique of such injuries.

Alcohol-related hand injuries: an unnecessary social and economic cost.

OpenAIRE

Marston, R. A.

1992-01-01

Severe hand injuries constitute the largest number of acute referrals to this plastic surgery unit, the admission of these patients often displacing routine admissions due to bed shortages, thus increasing waiting list time. This study showed that a high percentage of these injuries were alcohol-related and were therefore preventable. The economic cost to the unit is discussed.

Elbow, forearm, wrist, and hand injuries among sport rock climbers.

Holtzhausen, L M; Noakes, T D

1996-07-01

Sport rock climbing with its repetitive high-torque movements in gaining the ascent of a rock face or wall, often in steep overhanging positions, is associated with a unique distribution and form of upper limb injuries. In this article, we review the biomechanical aspects of sport rock climbing and the types of injuries commonly encountered in the forearm, wrist, and hand regions of elite sport rock climbers. Because elbow, forearm, wrist, and hand injuries predominate, representing 62% of the total injuries encountered, these anatomical areas have been selected for review. The predominant source of data are the published work of Bollen et al. The remaining sources were obtained through electronic search of the Medline and Current Contents Databases (last searched May 1995). German and French articles were included in the search criteria. Only studies dealing with acute soft tissue and overuse injuries amongst sport rock climbers were selected. Data were extracted directly from the sourced articles. The following injuries have been described in detail with regard to their presentation, diagnosis, treatment, and prevention amongst sport rock climbers: medial epicondylitis, brachialis tendonitis, biceps brachii tendonitis, ulnar collateral ligament sprain of the elbow, carpal tunnel syndrome, digital flexor tendon pulley sheath tears, interphalangeal joint effusions, fixed flexion deformities of the interphalangeal joints, and collateral ligament tears of the interphalangeal joints. Many of the injuries are specific to the handhold types used by the rock climber. Accurate diagnosis and effective treatment of these unique injuries will be facilitated by a wider understanding of the biomechanical aspects of rock climbing and an awareness of the patterns and incidence of injuries in this sport.

Retrospective study of work related traumatic hand injuries

Full Text Available The hand is an instrument extensively used in daily life activities- practical and professional; and it is, consequently, often injured, causing impact on productivity and on the country’s economy, also affecting the quality of life of individuals. When the lesion is work-related, it should be reported and referred by the service unit to Worker Health Reference Centre (CEREST. However, systems of records of occupational accidents are still little explored in Brazil. The aim of this work was to conduct a retrospective data survey on hand traumatic injuries of patients treated at CEREST in the municipality of Jundiaí, Sao Paulo state, in order to know the profile of these victims. Data were collected from the records of SINAN card - Severe Accident Research Sheet, in 2009. Of the 416 cases reported at SINAN, 45.2% were accidents involving the hand, which were reported mostly by private hospitals. 70.7% of the accidents reported occurred in the city (Jundiai and 88.3% of them took place within the premises of companies. Men aged between 19 and 39 years old were the most affected. Machine operators presented the highest accident incidence and fracture was the most frequent diagnosis. Temporary disability reached 80.3% of workers. 89.3% worked under formal contracts. Investment in record systems of labor accidents is essential because it would prevent underreporting and improve awareness of employees and public agencies regarding prevention and rehabilitation, thus avoiding inability of workers and damage to businesses and the government.

2011-01-01

Full Text Available Thorough research has been done on the characteristics of surgical anatomy and mechanogenesis of the explosion-related hand injuries received during military campaigns and in non-military explosion-related accidents. This research consisted of clinical, statistical and experimental-anatomical parts. 241 patient data files of the wounded during the military campaign in Afghanistan have been analysed as well as 70 patient data files of the injured in non-military explosion-related accidents. The most common, according to the patient data analysis, morphological variations of the explosion-related hand injuries were simulated during 24 in-field experiments by exploding hands of cadavers. The characteristics of the explosion-related hand injuries were analysed using radiography and precision preparation of the extremities after the in-field experiments. The correlations between the hand damage levels, the types of explosive materials, their orientation and position in hand during explosion have been identified.

Mole gun injury.

A mole gun is a weapon, which is used to trap and kill moles. This report provides an overview of the state of knowledge of mole gun injuries, comparable to blast injuries caused by fireworks, explosive or gunshot. Over a 2-year period, the authors reported their experience with ten hand injuries caused by mole gun. Radial side of the hand was often concerned, particularly the thumb. The authors explain their choices in the management of such lesions. Surgery was performed primarily and a large debridement currently seemed to offer the best outcome for the patient. Blast, crush, burns and lacerations may explain the higher rate of amputation to the digits. A long period of physiotherapy, specifically of the hand, was needed before the patient could return to work. This ballistic hand trauma encountered by surgeons requires knowledge and understanding of these injuries. It should be in accordance with firearms law because of severe injuries encountered and possible lethal wounds. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Imaging of hand injuries. Anatomic and radiodiagnostic considerations

International Nuclear Information System (INIS)

Schmitt, Rainer

2011-01-01

Imaging recommendations for assessing injuries of the forearm, wrist, metacarpus and the digits are given with respect to anatomic considerations. Furthermore, dedicated algorithms of advanced imaging are introduced with radiography as the primary diagnostic tool. High-resolution CT is used for detecting and staging the complex fractures of the radius and the wrist, whereas contrast-enhanced MRI serves for depicting the injured soft tissues. At the wrist, tears of the intrinsic ligaments and the TFCC are assessed with high accuracy when applying MR arthrography or CT arthrography. Dedicated radiologic tools as well as comprehensive reports are suggested in the management of the various hand injuries. (orig.)

2016-12-01

Injuries sustained to the hand and wrist are common, accounting for 20% of all emergency presentations. The economic burden of these injuries, comprised of direct (medical expenses incurred), indirect (value of lost productivity) and intangible costs, can be extensive and rise sharply with the increase of severity. This paper systematically reviews cost-of-illness studies and health economic evaluations of acute hand and wrist injuries with a particular focus on direct, indirect and intangible costs. It aims to provide economic cost estimates of burden and discuss the cost components used in international literature. A search of cost-of-illness studies and health economic evaluations of acute hand and wrist injuries in various databases was conducted. Data extracted for each included study were: design, population, intervention, and estimates and measurement methodologies of direct, indirect and intangible costs. Reported costs were converted into US-dollars using historical exchange rates and then adjusted into 2015 US-dollars using an inflation calculator RESULTS: The search yielded 764 studies, of which 21 met the inclusion criteria. Twelve studies were cost-of-illness studies, and seven were health economic evaluations. The methodology used to derive direct, indirect and intangible costs differed markedly across all studies. Indirect costs represented a large portion of total cost in both cost-of-illness studies [64.5% (IQR 50.75-88.25)] and health economic evaluations [68% (IQR 49.25-73.5)]. The median total cost per case of all injury types was US$6951 (IQR $3357-$22,274) for cost-of-illness studies and US$8297 (IQR $3858-$33,939) for health economic evaluations. Few studies reported intangible cost data associated with acute hand and wrist injuries. Several studies have attempted to estimate the direct, indirect and intangible costs associated with acute hand and wrist injuries in various countries using heterogeneous methodologies.

Morgan, W J; Slowman, L S

2001-01-01

Acute hand and wrist injuries in the athlete constitute a unique orthopaedic challenge. Because of the particular demands on the athlete (e.g., financial implications, coaching and administration pressures, self-esteem issues), a specialized management approach is often necessary. Common sites of injury include the ulnar collateral ligament of the thumb metacarpophalangeal joint, proximal interphalangeal joint, metacarpals and phalanges, scaphoid, hamate, and distal radius. Treatment of these injuries varies depending on the patient's age, sport, position played, and level of competition, but departures from standard practice as regards surgery, rehabilitation, and return to competition should never compromise care.

Hand safety for specialty crop production workers: a pilot study investigating frequencies of minor open-wound hand injuries and presence of pathogenic bacteria.

Science.gov (United States)

Pate, M L; Nummer, B

2013-10-01

The purpose of this study was to quantify the presence of minor open-wound hand injuries in addition to Salmonella, Staphylococcus aureus, coliforms, and Escherichia coli on the hands of farm workers who hand-harvest fruit crops in Utah. Data collection was conducted on four farms without USDA Good Agricultural Practices (GAP) certification and on two farms with GAP certification. This study identified essential safety issues that need to be addressed for improving the effectiveness of safety training for migrant farm workers. Farms that have a food safety audit program in place are less likely to have farm workers exposed to pathogenic bacteria and open-wound injuries to their hands. High frequency of S. aureus may indicate a potentially higher risk for wound infection within this worker population. This could lead to infections that are resistant to the antibiotics commonly used to treat ordinary staph infections, resulting in greater work loss time and medical expenses for these workers. Higher frequencies of bacterial presence on workers' hands on non-certified farms indicate a need to identify essential practices to improve worker hygiene habits and on-farm management practices to promote healthy hygiene. Open-wound injuries to migrant farm workers during hand-harvesting could create additional health problems with the possibility of infection and the spread of diseases. Continued research is needed to understand workers' acceptance of these injuries and barriers to personal protection.

Clavicle fractures in children occur twice as often as in adults. During a child's growth period they account for 10-15% of all fractures sustained. The questions which should be asked are how these fractures are sustained and under which circumstances are the children injured. In the study 256 children with clavicle fractures treated during the period 2008-2013 were analyzed. The underlying cause and place of injuries were classified using the ICD-10 classification system, using environmental causes of injury. The circumstances were in each case accidental injury. Environmental causes were traffic accidents (V01-V99) or mishaps/accidents (W00-X59). Fracture injuries were caused in traffic accidents in 24 (9.4%), and in mishaps/accidents in 232 (90.6%) children. Of the injuries caused by mishaps/accidents, in 204 children these were caused by falls (W00-W19). In 123 of them the injuries were caused by falls from a ground level, and in 81 were from a greater height. Direct blow injuries, caused by another person or a blunt instrument, weere the causes of fractures seen in 28 children. Place of fracture sustainment was dominantly at home. This was followed by injuries sustained outside in recreational areas, while least were suffered at school or kindergarden facilities. Bicycle riding was the cause of clavicle fractures in 48 children, which was 18.7% of all fractures seen. Sports related injuries and fractures were seen in 47 (18.4%) out of 256 children: 30 in football, 10 in defensive sports (wrestling, judo, karate), three in hockey, while basketball and gymnastics accounted for two each. Preschool children were injured more often while in the care of their parents while school aged children were adaquately protected, but in after-school activities they were often injured. The most common injuries after school were those suffered in traffic accidents and recreational sports activities. In the adolescent period, the most common injuries seen were again those in

Background: The purpose of this investigation was to explore prospectively the nature and duration of hand and wrist injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2012. Methods: Longitudinal prospective injury surveillance of the GB boxing squad was performed from 2005 to 2012. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 hours. Results: Finger carpometacarpal instability and finger metacarpophalangeal joint extensor hood and capsule sprain also known as "boxer's knuckle" injuries were significantly more common than other injury diagnoses. The number of injuries during training or competition was similar, which is remarkable given the far greater number of training hours than competition hours performed. Injury rate for hand and wrist injuries in competition was 347 injuries per 1000 hours, while the estimated injury rate in training was <0.5 injuries per 1000 hours. Conclusion: Carpometacarpal instability and boxer's knuckle were more common than any other kind of hand and wrist injury in this cohort of elite amateur boxers. The rate of hand and wrist injuries was higher in competition than in training. Our study highlights the importance of hand and wrist injury prevention in the competition environment.

Extraction of an impacted third molar is one of the most frequently performed techniques in oral and maxillofacial surgery. Surgeons can suffer numerous external injuries while extracting a tooth, with percutaneous injuries to the hand being the most commonly reported. In this article, we present a case involving a percutaneous injury of the surgeon's femoral region caused by breakage of the fissure bur connected to the handpiece during extraction of the third molar. We also propose precautions to prevent such injuries and steps to be undertaken when they occur.

Restoring tactile awareness through the rubber hand illusion in cervical spinal cord injury.

2013-10-01

Bodily sensations are an important component of corporeal awareness. Spinal cord injury can leave affected body parts insentient and unmoving, leading to specific disturbances in the mental representation of one's own body and the sense of self. Here, we explored how illusions induced by multisensory stimulation influence immediate sensory signals and tactile awareness in patients with spinal cord injuries. The rubber hand illusion paradigm was applied to 2 patients with chronic and complete spinal cord injury of the sixth cervical spine, with severe somatosensory impairments in 2 of 5 fingers. Both patients experienced a strong illusion of ownership of the rubber hand during synchronous, but not asynchronous, stroking. They also, spontaneously reported basic tactile sensations in their previously numb fingers. Tactile awareness from seeing the rubber hand was enhanced by progressively increasing the stimulation duration. Multisensory illusions directly and specifically modulate the reemergence of sensory memories and enhance tactile sensation, despite (or as a result of) prior deafferentation. When sensory inputs are lost, and are later illusorily regained, the brain updates a coherent body image even several years after the body has become permanently unable to feel. This particular example of neural plasticity represents a significant opportunity to strengthen the sense of the self and the feelings of embodiment in patients with spinal cord injury.

Causes of electrical deaths and injuries among construction workers.

2003-04-01

Contact with electrical current is the fourth leading cause of deaths of construction workers. This study evaluates electrical deaths and injuries to construction workers. Two sources of data were analyzed in detail: (1) 1,019 electrical deaths identified by the Bureau of Labor Statistics, Census of Fatal Occupational Injuries (CFOI) for the years 1992-1998; and (2) 61 electrical injuries identified between November 1, 1990 and December 31, 1998 from a George Washington University Emergency Department injury surveillance database. Contact with "live" electrical wiring, equipment, and light fixtures was the main cause of electrical deaths and injuries among electrical workers, followed by contact with overhead power lines. Among non-electrical workers, contact with overhead power lines was the major cause of death. Other causes included contact with energized metal objects, machinery, power tools, and portable lights. Arc flash or blast caused 31% of electrical injuries among construction workers, but less than 2% of electrical deaths. Adoption of a lockout/tagout standard for construction, and training for non-electrical workers in basic electrical safety would reduce the risk of electrical deaths and injuries in construction. Further research is needed on ways to prevent electrical deaths and injuries while working "live". Copyright 2003 Wiley-Liss, Inc.

More with less: A comparative kinematical analysis of Django Reinhardt's adaptations to hand injury.

Science.gov (United States)

Wininger, Michael; Williams, David J

2015-06-01

At the age of 18 years, jazz guitarist Django Reinhardt (1910-1953) sustained significant burns to his left-hand ring and little fingers; yet, subsequently, he relearned to play and achieved international fame, despite his injuries. Archive film footage and novel motion analysis software were used to compare movements of Django's fretting hand with that of six other guitarists of the same genre. Django employed greater abduction of index and middle fingers (-9.11 ± 6.52° vs -5.78 ± 2.41°; p < 0.001) and more parallel alignment of fingers to the guitar neck (157.7 ± 3.37° vs 150.59 ± 2.67°; p < 0.001) compared to controls. In response to debilitating hand injury, Django developed quantifiable compensatory adaptation of function of his remaining functional fingers by developing an original playing technique. Hand function following injury may be optimized by maximizing latent degrees of freedom in remaining digits, rather than through extensive surgical reconstruction or complex prostheses. Further study of adaptation strategies may inform prosthesis design. © The International Society for Prosthetics and Orthotics 2014.

MRI of the hand and wrist joint of climbers. Imaging of lesions and overstrain injury

Heuck, A.; Hochholzer, T.; Keinath, C.

1992-01-01

The hands and wrists of 20 top-level rock climbers with sports injuries and overstress abnormalities were compared with the hands and wrists of 10 normal volunteers. They were all studied with MR imaging at 1.5 T. The imaging protocol included spin-echo and gradient-echo sequences with 1- to 5-mm-thick contiguous slices in the axial, coronal and/or sagittal planes, depending on the location and nature of the suspected injury. Typical hand and wrist lesions depicted with MRI in climbers consisted of annular ligament tears, lesions of the flexor tendons, tenosynovitis, ganglion cysts, joint effusion and functional carpal tunnel syndrome. The MRI findings on these abnormalities were compared to normal findings and those with ultrasound and plain films. In addition, hypertrophic changes in the muscles, tendons, ligaments, and bones of top-level rock climbers were assessed morphometrically. MRI proved to be the superior imaging modality in the diagnosis of sports injuries and overstress abnormalities of the hand the wrist in rock-climbing athletes. (orig.) [de

Hand injury is the second most common work-related musculoskeletal injury among physical therapists (PTs) and other manual therapy professionals such as osteopaths, physiotherapists, chiropractors, acupuncturists and massage therapists. However, the nature and extent of this problem have not been fully explored yet. Therefore, the objective of this study was to review the existing literature published on the prevalence, risk factors, consequences, and prevention of hand injuries among PTs and similar healthcare professionals. The lifetime prevalence of hand injuries was about 15%-46%, and the annual prevalence was reported as 5%-30%. Thumb injuries were found to be the most prevalent of all injuries, accounting more than 50% of all hand-related problems. The most significant risk factors for job-related hand injuries were performing manual therapy techniques, repetitive workloads, treating many patients per day, continued work while injured or hurt, weakness of the thumb muscles, thumb hypermobility, and instability at the thumb joints. PTs reported modifying treatment technique, taking time off on sick leave, seeking intervention, shifting the specialty area, and decreasing patient contact hours as the major consequences of these injuries. The authors recommend that PTs should develop specific preventive strategies and put more emphasis on the use of aids and equipment to reduce the risk of an unnecessary injury.

Liquefied petroleum gas (LPG) is an odorless and colorless gas that is a mixture of hydrocarbons (propane and butane). It is now more commonly preferred among drivers as an auto-gas throughout the world because it is cheaper than petrol or diesel and produces the same amount of energy. Because of its rapid vaporization and consequent lowering of temperature, it may cause severe cold injuries. A 33-year-old male who suffered from hand burn due to LPG is presented in this article. In LPG-converted cars, if the conversion has not been done properly, LPG may leak. Thus, the public must be informed of this potential danger while undertaking repairs of their vehicles.

To describe and analyze the prevalence and epidemiological features of people with disability caused by injury in the Chinese population, and to provide scientific basis for developing the prevention and control programs on injuries. Statistics and intervention measures were used to analyze the data from the Second China National Sample Survey on injury-caused Disability. Cluster analysis was used to analyze the differences in regions. The overall prevalence of disability caused by injury was 99.68/10 000 which occupied 15.59% of all the disability, with multiple disability excluded. Physical disability and hearing disability accounted for 65.59% and 23.35% of all the injury-caused disability respectively, while those ranked Grade IV and III making up the majority (55.14% and 25.83%) of the disability, respectively. There were significant differences in the distribution of injury-caused disability among different age groups (χ(2) = 23 106.14, P Problems discovered by injury-caused disability in the Chinese population should not be ignored. Both physical and hearing disabilities appeared to be the two main types of disability while age, gender and region were related to injury-caused disability. Targeted strategies should be developed to decrease the injury-caused disability in China.

Commentary: Rehabilitation for Rural and Remote Residents Following a Traumatic Hand Injury

Directory of Open Access Journals (Sweden)

Gail A Kingston

Full Text Available A traumatic hand injury can involve damage to a number of structures including skin, nerves, tendons, muscle bone, and soft tissue. Impairments such as pain or stiffness and loss of range of motion can last for many years and result in a moderate to extreme impact on a person’s day-to-day life. Work, leisure, financial security, and emotional well-being often most affected. This commentary provides an analysis of those factors that inhibit (barriers and support (enablers the provision of hand therapy rehabilitation in rural and remote areas. Providing a collaborative and flexible rehabilitation programme to rural and remote residents following a traumatic hand injury can be seen as a challenge due to issues such as a limited access to health care services. Established protocols that work in regional or metropolitan locations are unlikely to be effective and innovative and pragmatic strategies are required. The provision of a collaborative and flexible rehabilitation programme regardless of residential location is an important part of the therapist’s intervention plan.

A main goal of rehabilitation strategies in humans with spinal cord injury is to strengthen transmission in spared neural networks. Although neuromodulatory strategies have targeted different sites within the central nervous system to restore motor function following spinal cord injury, the role of cortical targets remain poorly understood. Here, we use 180 pairs of transcranial magnetic stimulation for ∼30 min over the hand representation of the motor cortex at an interstimulus interval mimicking the rhythmicity of descending late indirect (I) waves in corticospinal neurons (4.3 ms; I-wave protocol) or at an interstimulus interval in-between I-waves (3.5 ms; control protocol) on separate days in a randomized order. Late I-waves are thought to arise from trans-synaptic cortical inputs and have a crucial role in the recruitment of spinal motor neurons following spinal cord injury. Motor evoked potentials elicited by transcranial magnetic stimulation, paired-pulse intracortical inhibition, spinal motor neuron excitability (F-waves), index finger abduction force and electromyographic activity as well as a hand dexterity task were measured before and after both protocols in 15 individuals with chronic incomplete cervical spinal cord injury and 17 uninjured participants. We found that motor evoked potentials size increased in spinal cord injury and uninjured participants after the I-wave but not the control protocol for ∼30 to 60 min after the stimulation. Intracortical inhibition decreased and F-wave amplitude and persistence increased after the I-wave but not the control protocol, suggesting that cortical and subcortical networks contributed to changes in corticospinal excitability. Importantly, hand motor output and hand dexterity increased in individuals with spinal cord injury after the I-wave protocol. These results provide the first evidence that late synaptic input to corticospinal neurons may represent a novel therapeutic target for improving motor function

Three cases of hand injury caused by meat grinders are presented. All 3 injuries involved the dominant hand and resulted in varying degrees of deformity. Two of the 3 patients arrived in the emergency room with the injured hand still firmly wedged in the meat grinder. Although these injuries continue to prove very mutilating, maximum restoration of the injured hand can be accomplished by careful extrication, followed by preservation and reconstruction of all viable tissues. Perioperative antibiotics and wound irrigation with antibiotic solution are recommended. Microsurgical technique can be of value in treating selected patients.

Sports activities were thought to be the major cause of meniscus injury in both men and woman, but our observations of non-athletic females show that the cause of meniscus injury was unrelated to any type of sports activity. This study revealed squat winnowing to be a major cause of meniscus injury in non-athletic females. This retrospective study was conducted in a tertiary care orthopaedic hospital which caters to a population of 10 million people. We assessed 120 non-athletic females who had received treatment in our hospital over a period of 2 years. The most probable cause of knee injury, per initial patient history, was recorded for all non-athletic females who presented clinical signs and symptoms of meniscus injury. The diagnoses were confirmed by relevant MRI and arthroscopy of patients' knees. All females who engaged in athletic activity and other females with unrelated, non-traumatic knee pathologies were excluded from the study. Through our study, we found that 42% (n = 50) of females suffered an injury during squat winnowing of rice, either at home or at work. Another 29% (n = 35) of females cited a history of slipping and spraining their knee as a cause of knee injury, while 19% (n = 16) of females suffered a knee injury during complex accidents such as a traffic accident. Finally, 13% (n = 16) of the females had no definite history of knee injury. Our observations add to the knowledge base of the various causes of meniscus tears; this study also revealed that socio-cultural factors influence and contribute to the mechanism of various types of knee injury.

Smoked marijuana as a cause of lung injury.

Science.gov (United States)

Tashkin, D P

2005-06-01

In many societies, marijuana is the second most commonly smoked substance after tobacco. While delta9-tetrahydrocannabinol (THC) is unique to marijuana and nicotine to tobacco, the smoke of marijuana, like that of tobacco, consists of a toxic mixture of gases and particulates, many of which are known to be harmful to the lung. Although far fewer marijuana than tobacco cigarettes are generally smoked on a daily basis, the pulmonary consequences of marijuana smoking may be magnified by the greater deposition of smoke particulates in the lung due to the differing manner in which marijuana is smoked. Whereas THC causes modest short-term bronchodilation, regular marijuana smoking produces a number of long-term pulmonary consequences, including chronic cough and sputum, histopathologic evidence of widespread airway inflammation and injury and immunohistochemical evidence of dysregulated growth of respiratory epithelial cells, that may be precursors to lung cancer. The THC in marijuana could contribute to some of these injurious changes through its ability to augment oxidative stress, cause mitochondrial dysfunction, and inhibit apoptosis. On the other hand, physiologic, clinical or epidemiologic evidence that marijuana smoking may lead to chronic obstructive pulmonary disease or respiratory cancer is limited and inconsistent. Habitual use of marijuana is also associated with abnormalities in the structure and function of alveolar macrophages, including impairment in microbial phagocytosis and killing that is associated with defective production of immunostimulatory cytokines and nitric oxide, thereby potentially predisposing to pulmonary infection. In view of the growing interest in medicinal marijuana, further epidemiologic studies are needed to clarify the true risks of regular marijuana smoking on respiratory health.

Forty-Year Follow-up of Full-Thickness Skin Graft After Thermal Burn Injury to the Volar Hand.

Weeks, Dexter; Kasdan, Morton L; Wilhelmi, Bradon J

2016-01-01

The hands are commonly affected in severe thermal burn injuries. Resulting contractures lead to significant loss of function. Burn contracture release and skin grafting are necessary to restore hand function. We report a case in which surgical reconstruction of a volar hand burn was performed with full-thickness skin grafting. The patient had a 40-year follow-up to assess the function and cosmesis of the repaired hand. We report a case in which a 15-month-old boy presented after receiving third-degree burns to the left volar hand, including the flexural aspects of the index, long, and ring fingers by placing it on a hot kitchen stove burner. The patient subsequently underwent scar contracture release and full-thickness skin grafting. Eleven years after reconstruction, further contractures developed associated with the patient's growth, which were reconstructed with repeat full-thickness skin graft from the inguinal region. No recurrence was witnessed afterward and 40 years after initial injury, the patient maintains full activities of daily living and use of his hand in his occupation. There is debate regarding the superiority of split-thickness versus full-thickness grafts during reconstruction. Our case strengthens the argument for durability of a full-thickness skin graft following thermal burn injury.

The aim of the research is to investigate work injuries among 13-17-year-old teenagers in Iceland, their causes and seriousness. Firstly, the prevalence of work injuries among the age-group is examined, as is the length of their absence from work, as well as the gender and age differences of both factors. Secondly, the type and the cause of the injuries are investigated. Thirdly, the most serious injuries and their causes are studied further. A survey was carried out amongst 2000 teenagers, aged 13-17, randomly selected from the Registers Iceland. The response rate was 48.4%. The teenagers were asked in a closed question about whether they had had an accident at work, and in an open one about the type and cause of the injury. A Chi-square test was used to test statistical significance: 95% confidence interval (CI). A fifth of the young people had had an accident at work, one quarter of the injured workers were absent from work because of the injury of which 5.9% for more than a week. The percentage of injured workers increases with age and has reached 30,7% among the 17-year-olds. Cuts and sprains were the most common injuries, whereas back injuries and bone fractures caused the longest absences. Sharp instruments were the most common cause of an injury, but lifting/carrying a (heavy) object as well as a fall of an object caused the longest absences. The prevalence of young workers' injuries and the seriousness of some of these injuries are of concern. In addition to education on occupational health and safety (OHS) and OHS training, future research must analyse if their labour market position threaten the young people's safety, and if it is the case, how to prevent it.

2003-10-01

Missed diaphragmatic perforation caused by penetrating trauma can lead to subsequent strangulation of a hollow viscus, which has prompted the use of invasive diagnostic procedures to exclude occult diaphragmatic injuries in asymptomatic, high-risk patients. The objective of this study was to determine the incidence of occult diaphragmatic injuries caused by stab wounds of the lower chest and upper abdomen, and to examine the natural history and consequences of missed diaphragmatic injuries. On the basis of patient data from two previous randomized studies from our institution, a retrospective analysis was performed on 97 patients treated for anterior stab wounds located between the nipple line, the umbilical level, and the posterior axillary lines not having indications for immediate surgical exploration. The patients were divided into two groups on the basis of their initial randomized management (open or laparoscopic exploration vs. expectant observation). In the exploration group (n = 47), four diaphragmatic injuries (9%) were detected (three left-sided and one right-sided). Excluding patients with associated injuries requiring surgical repair, the incidence of occult diaphragmatic injuries was 3 of 43 (7%). In the observation group (n = 50), there were two patients (4%) with delayed presentation of missed left-sided diaphragmatic injury 2 and 23 months later, respectively. Both injuries resulted from stab wounds of the left flank and presented with herniation of the stomach or small bowel and colon. The overall incidence of occult diaphragmatic injuries in left-sided thoracoabdominal stab wounds was 4 of 24 (17%), and was much lower after stab wounds of left epigastrium (0%), right lower chest (0%), and right epigastrium (4%). In asymptomatic patients with anterior or flank stab wounds of the lower chest or upper abdominal area, the risk of an occult diaphragmatic injury is approximately 7% which, if undetected, is associated with a high risk of subsequent

The hands and wrists of 20 top-level rock climbers with sports injuries and overstress abnormalities were compared with the hands and wrists of 10 normal volunteers. They were all studied with MR imaging at 1.5 T. The imaging protocol included spin-echo and gradient-echo sequences with 1- to 5-mm-thick contiguous slices in the axial, coronal and/or sagittal planes, depending on the location and nature of the suspected injury. Typical hand and wrist lesions depicted with MRI in climbers consisted of annular ligament tears, lesions of the flexor tendons, tenosynovitis, ganglion cysts, joint effusion and functional carpal tunnel syndrome. The MRI findings on these abnormalities were compared to normal findings and those with ultrasound and plain films. In addition, hypertrophic changes in the muscles, tendons, ligaments, and bones of top-level rock climbers were assessed morphometrically. MRI proved to be the superior imaging modality in the diagnosis of sports injuries and overstress abnormalities of the hand the wrist in rock-climbing athletes. (orig.).

Correlates of undefined cause of injury coded mortality data in Australia.

Science.gov (United States)

McKenzie, Kirsten; Chen, Linping; Walker, Susan M

The objective of this research was to identify the level of detail regarding the external causes of death in Australia and ascertain problematic areas where data quality improvement efforts may be focused. The 2003 national mortality dataset of 12,591 deaths with an external cause of injury as the underlying cause of death (UCOD) or multiple cause of death (MCOD) based on ICD-10 code assignment from death certificate information was obtained. Logistic regression models were used to examine the precision of coded external cause of injury data. It was found that overall, accidents were the most poorly defined of all intent code blocks with over 30% of accidents being undefined, representing 2,314 deaths in 2003. More undefined codes were identified in MCOD data than for UCOD data. Deaths certified by doctors were more likely to use undefined codes than deaths certified by a coroner or government medical office. To improve the quality of external cause of injuries leading to or associated with death, certifiers need to be made aware of the importance of documenting all information pertaining to the cause of the injury and the intent behind the incident, either through education or more explicit instructions on the death certificate and accompanying instructional materials. It is important that researchers are aware of the validity of the data when they make interpretations as to the underlying causes of fatal injuries and causes of injury associated with deaths.

To analyze the epidemiology status and risk factors of disabilities caused by injury in Guangdong province. Stratified multi-stage cluster sampling was used to identify 1530 subjects with disabilities (among them, 415 disabilities caused by injury), in the villages or districts in the four regions of Guangzhou, Qingyuan, Zhaoqing and Huizhou in 2010. Subjects were interviewed by trained staff with self-made questionnaires about the status of the disabled, then 415 disabled caused by injury were interviewed about the process of the injury causing disability. The variables in this survey included gender, regions, rural (urban) residences, occupation, age and injury style. The difference of injury were analyzed through χ(2) test, and the influencing factors were explored through classification tree model. The top five causes of disability were road traffic injury, fall, work-related injury, medical accident, scald or burn, accounting for 32.53% (135/415), 21.45% (89/415), 12.77% (53/415), 8.43% (35/415) and 5.06% (21/415), respectively. The proportion of male was higher than female in all disabilities caused by injury (295 male, 117 female, 3 unknown). Female had higher proportion 8.55% (10/117) than male 3.05% (9/295) with the cause of scald or burn (χ(2) = 6.302, P = 0.012), the proportion of rural residents 38.89%(84/216)was also higher than urban residents 25.63% (51/199) in disabilities caused by traffic accident (χ(2) = 43.850, P work-injury mainly caused disability in 25 - 44 age group, 85.71% (30/35) medical accident and 76.20% (16/21) scald or burn mainly caused disability in 0 - 14 age group, the injury caused by the fall was 62.50% (5/8) in 65- age group.

Objective To apply human performance concepts in an attempt to understand the causes of and prevent laparoscopic bile duct injury. Summary Background Data Powerful conceptual advances have been made in understanding the nature and limits of human performance. Applying these findings in high-risk activities, such as commercial aviation, has allowed the work environment to be restructured to substantially reduce human error. Methods The authors analyzed 252 laparoscopic bile duct injuries according to the principles of the cognitive science of visual perception, judgment, and human error. The injury distribution was class I, 7%; class II, 22%; class III, 61%; and class IV, 10%. The data included operative radiographs, clinical records, and 22 videotapes of original operations. Results The primary cause of error in 97% of cases was a visual perceptual illusion. Faults in technical skill were present in only 3% of injuries. Knowledge and judgment errors were contributory but not primary. Sixty-four injuries (25%) were recognized at the index operation; the surgeon identified the problem early enough to limit the injury in only 15 (6%). In class III injuries the common duct, erroneously believed to be the cystic duct, was deliberately cut. This stemmed from an illusion of object form due to a specific uncommon configuration of the structures and the heuristic nature (unconscious assumptions) of human visual perception. The videotapes showed the persuasiveness of the illusion, and many operative reports described the operation as routine. Class II injuries resulted from a dissection too close to the common hepatic duct. Fundamentally an illusion, it was contributed to in some instances by working too deep in the triangle of Calot. Conclusions These data show that errors leading to laparoscopic bile duct injuries stem principally from misperception, not errors of skill, knowledge, or judgment. The misperception was so compelling that in most cases the surgeon did not

This study was undertaken to analyze the characteristics and risk factors relating to fatalities and injuries caused by paragliding. The judicial examination reports and hospital documents of 82 patients traumatized in 64 accidents during 242 355 paragliding jumps between August 2004 and September 2011 were analyzed. In these accidents, 18 of the 82 patients lost their lives. In the patients with a confirmed cause of accident, most of them were involved with multiple fractures and internal organ injuries (n=8, 44.4%). We investigated the incidence of paragliding injuries, the types of the injuries, and the severity of affected anatomical regions. The findings are significant for the prevention of paragliding injuries and future research.

2017-10-01

A 51-year-old man with an incomplete C6 spinal cord injury sustained 26 yrs ago attended twenty 2-hr visits over 10 wks for robot-assisted hand training driven by myoelectric pattern recognition. In each visit, his right hand was assisted to perform motions by an exoskeleton robot, while the robot was triggered by his own motion intentions. The hand robot was designed for this study, which can perform six kinds of motions, including hand closing/opening; thumb, index finger, and middle finger closing/opening; and middle, ring, and little fingers closing/opening. After the training, his grip force increased from 13.5 to 19.6 kg, his pinch force remained the same (5.0 kg), his score of Box and Block test increased from 32 to 39, and his score from the Graded Redefined Assessment of Strength, Sensibility, and Prehension test Part 4.B increased from 22 to 24. He accomplished the tasks in the Graded Redefined Assessment of Strength, Sensibility, and Prehension test Part 4.B 28.8% faster on average. The results demonstrate the feasibility and effectiveness of robot-assisted training driven by myoelectric pattern recognition after spinal cord injury.

Modulation of hand aperture during reaching in persons with incomplete cervical spinal cord injury.

Stahl, Victoria A; Hayes, Heather B; Buetefisch, Cathrin M; Wolf, Steven L; Trumbower, Randy D

2015-03-01

The intact neuromotor system prepares for object grasp by first opening the hand to an aperture that is scaled according to object size and then closing the hand around the object. After cervical spinal cord injury (SCI), hand function is significantly impaired, but the degree to which object-specific hand aperture scaling is affected remains unknown. Here, we hypothesized that persons with incomplete cervical SCI have a reduced maximum hand opening capacity but exhibit novel neuromuscular coordination strategies that permit object-specific hand aperture scaling during reaching. To test this hypothesis, we measured hand kinematics and surface electromyography from seven muscles of the hand and wrist during attempts at maximum hand opening as well as reaching for four balls of different diameters. Our results showed that persons with SCI exhibited significantly reduced maximum hand aperture compared to able-bodied (AB) controls. However, persons with SCI preserved the ability to scale peak hand aperture with ball size during reaching. Persons with SCI also used distinct muscle coordination patterns that included increased co-activity of flexors and extensors at the wrist and hand compared to AB controls. These results suggest that motor planning for aperture modulation is preserved even though execution is limited by constraints on hand opening capacity and altered muscle co-activity. Thus, persons with incomplete cervical SCI may benefit from rehabilitation aimed at increasing hand opening capacity and reducing flexor-extensor co-activity at the wrist and hand.

Objective: To observe the effects of functional training combined with self-made hand flexing training band in treatment of scar contracture after burn injury of dorsal hand. Methods: Forty-six patients with scar contracture after deep partial-thickness or full-thickness burn injury of dorsal hand hospitalized in our department from March 2013 to February 2015 were divided into routine training group (RT, n =18) and comprehensive training group (CT, n =28) according to their willingness. Two weeks after the wounds were healed, patients in group RT were treated with functional training of hands and self-made pressure gloves, while patients in group CT were treated with self-made hand flexing training band (consisting of nylon strap, flexing band, and velcro) on the basis of those in group RT. All patients were treated for 3 months. Before and after treatment, scar condition of affected hands was assessed with Vancouver Scar Scale (VSS). The range of motion of joints of affected hands was measured by Total Active Movement (TAM) Scale. The function of affected hands was evaluated by Carroll Upper Extremity Function Test. Data were processed with t test, chi-square test, and Mann-Whitney U test. Results: (1) The score of VSS in patients of group RT was (10.0±1.9) points before treatment and (4.4±1.4) points after treatment, with the improved score of (5.6±1.0) points. The score of VSS in patients of group CT was (10.5±1.8) points before treatment and (4.6±1.4) points after treatment, with the improved score of (5.9±1.2) points. There was no statistically significant difference in the improved score of patients between the two groups ( t =0.834, P >0.05). The score of VSS in patients of groups RT and CT after treatment was significantly lower than that before treatment (with t values respectively 14.014 and 10.003, P values below 0.01). (2) Before treatment, the ratios of excellent and good results according to TAM were 2/9 in patients of group RT and 3/14 in

In the pediatric gymnast, stress-related physeal injuries have been well described with characteristic imaging findings. However, a spectrum of overuse injuries, some rarely reported in the literature, can be encountered in the gymnast's hand and wrist. To demonstrate the MR appearance of a spectrum of overuse injuries in the skeletally immature wrist and hand of pediatric gymnasts. A total of 125 MR exams of the hand and wrist in skeletally immature children were performed at our institution during a 2-year period. Clinical histories were reviewed for gymnastics participation. MR studies of that subpopulation were reviewed and abnormalities tabulated. Of the MR studies reviewed, ten gymnasts were identified, all girls age 12-16 years (mean age 14.2 years) who presented with wrist or hand pain. Three of these children had bilateral MR exams. Abnormalities included chronic physeal injuries in three children. Two girls exhibited focal lunate osteochondral defects. Triangular fibrocartilage tears were present in three girls, one of whom had a scapholunate ligament tear. Two girls manifested metacarpal head flattening and necrosis. A variety of soft-tissue and osseous lesions can be encountered in the skeletally immature gymnast. Familiarity with these stress-related injuries is important for accurate diagnosis. (orig.)

The use of hand sanitizer is effective in preventing the transmission of disease. Many hand sanitizers are alcohol-based, and significant intoxications have occurred, often in health care facilities, including the emergency department (ED). We present this case to highlight potential toxicity after the ingestion of an ethanol-based hand sanitizer. A 36-year-old man presented to the ED with ethanol intoxication. Ethanol breath analysis was measured at 278 mg/dL. After 4 h, the patient was less intoxicated and left the ED. Thirty minutes later, he was found apneic and pulseless in the ED waiting room bathroom after having ingested an ethanol-based hand sanitizer. Soon after a brief resuscitation, his serum ethanol was 526 mg/dL. He never regained consciousness and died 7 days later. No other cause of death was found. The case highlights the potential for significant toxicity after the ingestion of a product found throughout health care facilities. Balancing the benefit of hand sanitizers for preventing disease transmission and their potential misuse remains a challenge. Copyright © 2013 Elsevier Inc. All rights reserved.

Recent studies have raised the possibility of a predisposition to mononeuropathies in a number of professions including musicians, cleaners, and industrial workers. There are, however, no previous reports of increased rates of mononeuropathies in the culinary arts. The authors report three cases of mononeuropathies occurring in professional chefs that presented over a 3-month period in the same outpatient clinic, with a case each of distal ulnar neuropathy, distal median motor neuropathy (thenar motor syndrome) and posterior interosseous neuropathy. There was no history of direct hand trauma in any of the patients. In all three patients, the injuries occurred exclusively in the dominant hand, further strengthening the argument for an occupational link.

Pilots of fixed wing commercial aircraft face numerous occupational hazards. Low back pain is among the most common and costly workplace injury, though relatively little is known about causes of back injuries among pilots. The awkward lifting and twisting maneuvers in the flight deck to position flight bags has not been described as a cause of occupational back injury among pilots. A case series of low back injuries among pilots was identified and described by a retrospective review of charts at an airport-based clinic. Circumstances of occupational back injury, initial direct medical costs, treatment, and work status following evaluation were described. Over a 6-yr period, 37 occupational low back injuries among 35 pilots were evaluated and treated. Of these, 24 (65%) involved flight bags. Only 27% of pilots with flight bag-associated injuries were returned to work after initial evaluation; medications with sedating properties were frequently required for treatment. Injuries due to slips, trips, and falls, typically in jet bridges or associated with hotel shuttles, were common among pilots with back injuries not related to flight bags. The majority of occupational low back injuries seen among pilots in an airport based clinic were attributable to use of flight bags. Substituting electronic flight bags for traditional flight bags could contribute to back injury prevention among pilots.

In Sub-Saharan Africa, infections and undernutrition are the leading causes of childhood death; however injuries are now contributing significantly to childhood morbidity and mortality. To determine the aetiology, morbidity and mortality associated with injuries in children in South-Western Nigeria. This was an observational cross-sectional study of consecutive childhood injury attendances and admissions into the hospital's Children Emergency Room (CHER) over a one-year period. Socio-demographic data as well as the data on the cause, site, and possible risks of injury; parts of the body affected and eventual outcome of the patients were documented. Injury accounted for 382 (10.6%) of the 3,604 attendances, 142 (11.9%) of 1193 admissions and 11 (20.4%) of 54 deaths in CHER. Their ages ranged from six weeks to 15 years, with a mean (SD) of 6.7 (3.9) years, and a male:female ratio of 1.6:1. Road traffic accidents, 130 (34.0%), were the most common cause, followed by falls 119 (31.2%), cuts 44 (11.5%), bits 26 (6.8%), and burns 24 (6.3%). Injuries occurred mostly at home 154 (40.1%), on the road 142 (37.4%), and at school 59 (15.2%). Lack of supervision and/or poor anticipation of potential dangers were the leading risks associated with childhood injuries. Injuries contribute significantly to childhood deaths in South-Western Nigeria. A well-orchestrated public enlightenment programme to improve home, school, and road supervision of children as well as concerted efforts to make these places safer could help ameliorate the situation.

In France, hand injuries are the number one cause of all accidents referred to our hospital casualty departments. Their human and economic consequences are very serious. Two thirds of these accidents arise during everyday living activities and a third of them happen at work. The specific prevention of hand injuries in each of these domains has not been sufficiently developed. The authors present the national prevention campaign recently set up by the FESUM. The campaign took place in the form of events held in different towns in France. Each event, lasting from a minimum of 2 days to 10 days maximum, included press conferences, prevention workshops specific to hand injuries, theatrical animation for youngsters, conferences for the general public, meetings in industrial or training college environments, photography and video exhibitions, and the publication of pamphlets and posters. These manifestations were carried out in partnership with the association APAVC and the voluntary involvement of surgeons from the FESUM hand centres in each town visited. Over a period of 2 years, 22 large or medium-sized towns were able to hold these campaign events. By this means, thousands of people - adults, schoolchildren or young, professional apprentices - were made aware of hand injuries and how to prevent them. We were able to reinforce the broadcasting of simple prevention messages launched by the campaign, particularly with regard to wearing gloves for all manual activities, with the help of heavy local, regional and national media coverage. This campaign was the first widespread action of its kind, aimed specifically at the prevention of hand injuries. Furthermore, it was a way of strengthening the credibility of the FESUM hand emergency centres with the health authorities and to promote the services available to patients. © Georg Thieme Verlag KG Stuttgart · New York.

Worldwide, approximately 3 500 000 people die every year as a result of injuries from external causes, in Venezuela these arte the third leading cause of overall morbidity. Nevertheless, in the country there are no records of the defining aspects of prehospital emergency care as a tool to address this socio-health problem, the aim of this investigation. A descriptive, transversal, field study based on the information recorded daily for a year paramedics was performed. A total 1493 injured by external causes were reported, with a mean age of 29.5 ± 12 years, 84.5% male. Injuries mostly less-moderate (69.4%) were due to severe land transport accidents (70.9%) occurred during the day (75.9%), between monday and friday (72.9%), attended in 20 minutes or less, and transferred in 97.3% of cases. The economically productive young men in areas with higher population density and urbanism are mostly affected by injuries from external causes. In both genres land transport accidents are the most common causes of injury with lower-moderate severity. The care that paramedics provide can be considered adequate.

To identify the leading causes of injury in children aged 0-4 years by single year of age using injury submechanisms and present a brief epidemiologic profile of each cause. Hospitalisation data for New South Wales from 1999 to 2009 were used to identify the leading causes of injury for children aged 0-4 years by single year of age. For each leading cause, rates over time and by sex were calculated by single year of age. Associated age and sex risk ratios were estimated. The leading causes of injury for children aged leading injury cause exhibited an age pattern that remained stable over time and by sex. Age predicted falls while being carried and both age and sex predicted the remaining leading injury causes, with age and sex interacting to predict burns by hot non-aqueous substances. Epidemiologic analysis using single-year age intervals and injury submechanisms results in a clearer picture of injury risk for young children. The findings of this study provide detailed information regarding the leading causes of hospitalised injury in young children by age and sex. Child health-care providers can use this information to focus discussions of child development and injury risk with families of young children and suggest appropriate prevention measures in terms of a child's age and sex. © 2012 The Authors.

Retrospective and prospective observational. Analyse causes of death after traumatic spinal cord injury (tSCI) in persons surviving the first year post injury, and establish any trend over time. Two spinal centres in Great Britain. The sample consisted of 5483 patients with tSCI admitted to Stoke Mandeville and Southport spinal centres who were injured between 1943 and 2010, survived first year post injury, had residual neurological deficit on discharge and were British residents. Mortality information, including causes of death, was collected up to 31 December 2014. Age-standardised cause-specific mortality rates were calculated for selected causes of death, and included trends over time and comparison with the general population. In total, 2322 persons (42.3% of the sample) died, with 2170 (93.5%) having a reliable cause of death established. The most frequent causes of death were respiratory (29.3% of all certified causes), circulatory, including cardiovascular and cerebrovascular diseases (26.7%), neoplasms (13.9%), urogenital (11.5%), digestive (5.3%) and external causes, including suicides (4.5%). Compared to the general population, age-standardised cause-specific mortality rates were higher for all causes, especially skin, urogenital and respiratory; rates showed improvement over time for suicides, circulatory and urogenital causes, no significant change for neoplasms, and increase for skin and respiratory causes. Leading causes of death after tSCI in persons surviving the first year post injury were respiratory, circulatory, neoplasms and urogenital. Cause-specific mortality rates showed improvement over time for most causes, but were still higher than the general population rates, especially for skin, urinary and respiratory causes.

Full Text Available Abstract Background Premature death from suicide is a leading cause of death worldwide. However, the pattern and risk factors for suicide and other external cause injuries are not well understood. This study investigates mortality from suicide and other injuries and associated risk factors in China. Methods A prospective cohort study of 169,871 Chinese adults aged 40 years and older was conducted. Mortality due to suicide or other external cause injuries was recorded. Results Mortality from all external causes was 58.7/100,000 (72.3 in men and 44.4 in women: 14.1/100,000 (14.2 in men and 14.2 in women for suicide and 44.6/100,000 (58.1 in men and 30.2 in women for other external cause injuries. Transport accidents (17.2/100,000 overall, 23.4 in men and 10.8 in women, accidental poisoning (7.5/100,000 overall, 10.2 in men and 4.8 in women, and accidental falls (5.7/100,000 overall, 6.5 in men and 5.0 in women were the three leading causes of death from other external cause injuries in China. In the multivariable analysis, male sex (relative risk [RR] 1.56, 95% confidence interval [CI] 1.03-2.38, age 70 years and older (2.27, 1.29-3.98, living in north China (1.68, 1.20-2.36 and rural residence (2.82, 1.76-4.51 were associated with increased mortality from suicide. Male sex (RR 2.50, 95% CI 1.95-3.20, age 60-69 years (1.93, 1.45-2.58 and 70 years and older (3.58, 2.58-4.97, rural residence (2.29, 1.77-2.96, and having no education (1.56, 1.00-2.43 were associated with increased mortality from other external cause injuries, while overweight (0.60, 0.43-0.83 was associated with decreased risk of mortality from other external cause injuries. Conclusions External cause mortality has become a major public health problem in China. Developing an integrated national program for the prevention of mortality due to external cause injuries in China is warranted.

We studied the epidemiology of paediatric firework-related injury in the urban population of Delhi during the festival of lights (Diwali). In this prospective observational study, data were collected on the day of Diwali for two consecutive years, 2010 and 2011. All children with firework injuries coming to the emergency room were included in the study. Data were recorded in a predesigned proforma. Of the 65 cases, 75% were males and 25% were females; most children were more than 10 years of age and majority (90%) of them were unsupervised. Half (49%) of the cases were due to misuse of the fireworks or erratic behaviour, among which the most common observed mode was igniting cracker while holding it (18 cases; 24% of total injuries), which led to injuries to the hand and palm. Device failure was the next common cause for firework injuries, including unexpected blast of the crackers and string bomb as the most common. Overall, the most commonly injured body sites were hands (62%), face (32%) and eyes (10%). Crackers and string bomb mainly caused injuries to hands; fountains and gunpowder caused injuries to the face. Sixty (94%) children were managed conservatively and 5 (6%) required skin grafting and tendon repair. We recommend parental supervision especially for males, wearing non-synthetic and non-flowing clothes, promoting branded crackers and educational campaigns in schools to curtail the rising trend in firework-related injuries in the paediatric population. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Esparza, Erick; Pinos, Angel; Mayorga Patricio; Torres, Neira

2005-01-01

The raquimedular injury constitutes an important chapter inside the Neurotraumatology, due to its frequent association in the politrauma it forms part of and to the serious consequences that it causes. The collection of data for this is taken from the patient's medical histories: age, causes, associated wounds, the surgical procedure carried out, and the results obtained are taken into consideration. The backbone is divided in various segments with the purpose of classifying the wound as well as to appreciate the treatment performed in each case. The Frankel scale that's reports the neurological commitment in this type of wound is utilized in the initial appraisal and in the monitoring of the patient. Of the total of cases (n=55), the most frequent age of presentation was in the rank from 30 to 60 years old, with 35 cases (63%) free falls and traffic accidents are registered as the most frequent causes with 36 cases (65%), and 11 cases (20%) respectively, the raquideo level most affected is found in the lower cervical column with 20 cases (36.3%) and the hinge toracolumbar with 22 cases (40%). We found 17 cases (30.9) in the degree A of the Frankel scale, and of these, 12 cases (21%) corresponds to cervical injury. Imaging studies, computer tomography CT and magnetic nuclear resonance MRI were used. (The author)

To describe and analyze the causes of emergency care services for intentional injuries, especially those caused by domestic violence, at four public hospitals in Mexico City. A cross-sectional study was conducted between January and April 1998, which included variables related with the victim, the aggressor, and the medical care provided to the victim. A questionnaire was applied to individuals who had been injured intentionally. Statistical analysis of data consisted of simple frequencies, the chi 2 test, and odds ratios (OR) with 95% confidence intervals (CI). A logistic regression model was also used to adjust for variables associated with the injury requiring emergency medical care. A total of 598 cases of intentional injuries were analyzed, 16% of which were due to domestic violence. Females were the most frequent victims (76%), followed by young people between 15 and 29 years old (46%). Variables associated with medical care due to injuries by domestic violence were: age 30 or older (OR 2.36, 95% CI 1.13-4.90), female gender (OR 8.60 95% CI 4.25-17.40), history of injuries (OR 4.93 95% CI 2.03-11.95), home as place of occurrence (OR 36.25 95% CI 16.59-79.18), and low education level (OR 2.33 95% CI 1.03-5.26). Study findings are consistent with those from other studies and call for enforcement of the Mexican Official Norm for Medical Care of Domestic Violence (Norma Oficial Mexicana para la Atención Médica de la Violencia Familiar) established in March 2000.

Cost per case or total cost? The potential of prevention of hand injuries in young children – Retrospective and prospective studies

Directory of Open Access Journals (Sweden)

Carlsson Katarina

2008-07-01

Full Text Available Abstract Background Health-care costs for hand and forearm injuries in young children are poorly documented. We examined costs in 533 children injured years 1996–2003. Methods Health-care costs and costs for lost productivity were retrospectively calculated in children from three catchment areas in Sweden. Seven case categories corresponding to alternative prevention strategies were constructed. Results Over time, diminishing number of ward days reduced the health-care cost per case. Among children, the cost of lost productivity due to parental leave was 14 percent of total cost. Fingertip injuries had low median costs but high total costs due to their frequency. Complex injuries by machine or rifle had high costs per case, and despite a low number of cases, total cost was high. Type of injury, surgery and physiotherapy sessions were associated with variations in health-care cost. Low age and ethnic background had a significant effect on number of ward days. Conclusion The costs per hand injury for children were lower compared to adults due to both lower health-care costs and to the fact that parents had comparatively short periods of absence from work. Frequent simple fingertip injuries and rare complex injuries induce high costs for society. Such costs should be related to costs for prevention of these injuries.

Types and severity of operated supraclavicular brachial plexus injuries caused by traffic accidents.

Kaiser, Radek; Waldauf, Petr; Haninec, Pavel

2012-07-01

Brachial plexus injuries occur in up to 5% of polytrauma cases involving motorcycle accidents and in approximately 4% of severe winter sports injuries. One of the criteria for a successful operative therapy is the type of lesion. Upper plexus palsy has the best prognosis, whereas lower plexus palsy is surgically untreatable. The aim of this study was to evaluate a group of patients with brachial plexus injury caused by traffic accidents, categorize the injuries according to type of accident, and look for correlations between type of palsy (injury) and specific accidents. A total of 441 brachial plexus reconstruction patients from our department were evaluated retrospectively(1993 to 2011). Sex, age, neurological status, and the type and cause of injury were recorded for each case. Patients with BPI caused by a traffic accident were assessed in detail. Traffic accidents were the cause of brachial plexus injury in most cases (80.7%). The most common type of injury was avulsion of upper root(s) (45.7%) followed by rupture (28.2%), complete avulsion (16.9%) and avulsion of lower root(s) (9.2%). Of the patients, 73.9% had an upper,22.7% had a complete and only 3.4% had a lower brachial plexus palsy. The main cause was motorcycle accidents(63.2%) followed by car accidents (23.5%), bicycle accidents(10.7%) and pedestrian collisions (3.1%) (paccidents had a higher percentage of lower avulsion (22.7%) and a lower percentage of upper avulsion (29.3%), whereas cyclists had a higher percentage of upper avulsion (68.6%) based on the data from the entire group of patients (paccidents (9.3%,paccidents),significantly more upper and fewer lower palsies were present. In the bicycle accident group, upper palsy was the most common (89%). Study results indicate that the most common injury was an upper plexus palsy. It was characteristic of bicycle accidents, and significantly more common in car and motorcycle accidents. The results also indicate that it is important to consider the

Objective To describe the causes of underreporting of occupational injuries and adverse events as identified in the international literature and by key informants in the area of health and risk prevention in Chile. Methods The study uses a qualitative descriptive approach. This includes a systematized literature review that follows the SALSA method (Search, Appraisal, Synthesis and Analysis) and is in line with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). In addition, interviews were conducted with informants in the area of health and risk prevention in Chile. Results The leading causes of underreporting of occupational injuries as described in the literature and by key informants were economic factors and ignorance. With regard to adverse events, the principal causes indicated were fear of sanctions, limited support provided by the authorities, lack of knowledge, and excessive workload. Conclusions It is important to continue working to strengthen the reporting of occupational injuries and adverse events and to implement measures aimed at minimizing factors that appear to be the leading causes of underreporting. In the case of occupational injuries, this means making sure that economic factors are not an impediment but rather an incentive to reporting. With respect to adverse events, steps should be taken to eliminate the fear of sanctions and to develop recommendations, focusing more on systemic improvements than on individuals, to promote joint learning. In both cases it will be necessary to combat ignorance through continuous, systematic training and support.

The injuries sustained in 295 karate contests were analysed. It was noted that in 25 per cent of the contests there was some sort of injury, and in 10 per cent the injury was severe enough to cause the withdrawal of the participant. Injury seemed to occur most commonly among lower-grade participants and more often in the first hour of each day's competition. Protective padding of the arms, legs, feet and hands, and the use of gumshields and protective boxes appeared to reduce the incidence and severity of injury.

This article examines the stages in developing an information system for injuries from external causes (Sistema de Información de Lesiones de Causa Externa-SILEX), as well as its limitations and achievements. SILEX is a Web-based application for collection, quality control, presentation, and analysis of data available from the hospital system for surveillance of injuries from external causes created by Ministry of Health of El Salvador with data from the hospital emergency services. This system maintains comprehensive information on the injured person-type of injury, intention, injury site, activity being performed at the time of injury, risk factors, etc.-in the form of tables, graphs, and maps, which streamlines the development of intervention plans and prevention initiatives for these types of injuries in El Salvador. This experience is an example of what can be done to close the information gap on injuries by external causes in the Region of the Americas.

Full Text Available Perforating globe injury is the leading cause of monocular blindness and vision loss. A 58-year-old male was injured by acupuncture needle during acupuncture treatment for his cerebral infarction. To the best of our knowledge, this is the first case report of perforating injury of the eyeball and traumatic cataract caused by acupuncture. The patient was hospitalized due to diagnosis of perforating ocular injury, traumatic cataract, and corneal and iris perforating injury. Moreover, he had to accept treatments of phacoemulsification, anterior vitrectomy along with intraocular lens implantation in the sulcus to improve his visual acuity. As acupuncture therapy has been widely performed for various diseases and achieved highly approval, the aim of this report is to remind acupuncturists operating accurately to avoid unnecessary injury during the treatment process, or the cure can also become the weapon.

Maxillofacial injuries are among the commonest forms of body injuries. There are three divisions, namely, facial bone fractures, soft tissue injuries, and dentoalveolar injuries. Etiologies include motor vehicle accidents, assaults, falls, and sporting injuries. The aim of this study was to determine the profiles including the causes of maxillofacial injuries seen in an urban government hospital in the mainland of Penang State, Malaysia. This was a cross-sectional study that recruited cases reported within a period of 1 year. The source population was maxillofacial injury patients presenting to the Oral and Maxillofacial Surgery Department of an urban hospital in the Penang Mainland, North Malaysia between May 2007 and May 2008. Cases of patients involved in accidents that occurred outside the reference vicinity were excluded. A case report form was developed and completed by the attending clinicians. Data were analyzed using spss version 12.0. A total of 194 cases were studied, with the mean patient age being 27.8 (SD 15.20) years. The majority of patients were Malay men between 20 and 29 years of age. The main cause of injury was motorcycle accident (53.6%). The commonest injury (in isolation/combination with other injuries) involved the soft tissues (87.2%), dentoalveolar region (33.4%), and facial bones (23.9%). Laceration was the commonest soft tissue injury, and crown fracture was the most frequent dentoalveolar injury. The facial bone that was most highly involved in the injury was the zygoma. Subjects involved in motorcycle accidents had a significantly higher incidence of sustaining facial bone fractures. Motorcycle accidents were the commonest cause of maxillofacial injuries in the Penang Mainland, Malaysia. Most patients were young men. Hence, it is prudent to reinforce appropriate road safety and awareness interventions particularly focusing young male motorcyclists so as to reduce the risk of accidents. © 2011 John Wiley & Sons A/S.

Oligodendrocyte Injury and Pathogenesis of HIV-1-Associated Neurocognitive Disorders

2016-07-01

Full Text Available Oligodendrocytes wrap neuronal axons to form myelin, an insulating sheath which is essential for nervous impulse conduction along axons. Axonal myelination is highly regulated by neuronal and astrocytic signals and the maintenance of myelin sheaths is a very complex process. Oligodendrocyte damage can cause axonal demyelination and neuronal injury, leading to neurological disorders. Demyelination in the cerebrum may produce cognitive impairment in a variety of neurological disorders, including human immunodeficiency virus type one (HIV-1-associated neurocognitive disorders (HAND. Although the combined antiretroviral therapy has markedly reduced the incidence of HIV-1-associated dementia, a severe form of HAND, milder forms of HAND remain prevalent even when the peripheral viral load is well controlled. HAND manifests as a subcortical dementia with damage in the brain white matter (e.g., corpus callosum, which consists of myelinated axonal fibers. How HIV-1 brain infection causes myelin injury and resultant white matter damage is an interesting area of current HIV research. In this review, we tentatively address recent progress on oligodendrocyte dysregulation and HAND pathogenesis.

Maguiña, Pirko; Palmieri, Tina L; Greenhalgh, David G

2004-01-01

Treadmills are a burn risk for children. A child's hand can get trapped in the conveyor belt, causing friction burns to the underlying tissue. The purpose of this retrospective study was to review the characteristics and treatment of treadmill-related burns in children from 1998 to 2002. Ten patients, at a mean age of 3.4 years, sustained injuries associated with treadmill use. Trapping of the hand between the conveyor belt and the base was the most frequent injury mechanism. Burn location was predominantly on fingers and palms. Four patients required operative intervention. All patients required specialized wound care as well as scar management and occupational therapy. Treadmills pose a danger to children. Current safety devices are ineffective for preventing serious hand injuries in children. New design modifications and public awareness are needed to improve child safety.

We gathered seven specialists from various fields who are interested in worker injury prevention programs, based on cases of patients who had suffered refractory injuries requiring hand surgery because of industrial accidents. The patients were asked to write their thoughts and ideas on the theme, "Measures that must be implemented to prevent arm injuries." The content obtained was classified into different categories, using the KJ method, and was scripted to sort out the items. As a result, the following eleven points were identified as measures to prevent serious hand surgery-related injuries: 1. Purchase safe machinery, 2. Create a list of machines that require caution, 3. Enclose a machine's various rotating parts, 4. Carry out periodic maintenance work on the machines, 5. Indicate dangerous areas by putting up signs that attract attention, 6. Illuminate the rotating parts more brightly and avoid placing objects around them, 7. Systematically carry out safety education that creates a strong impact, 8. Encourage workers to look after their own health, 9. Announce policies on health and safety, 10. Re-examine the operational procedures, and 11. Be prepared in case an accident occurs. A perspective based on the results of this research is deemed important in creating a workplace improvement manual in the future.

The aim of this study was to highlight the differences in injury rates between populations through a descriptive epidemiological study of population-level trends in injury mortality for the high-income countries of Australia, Canada and the United States. Mortality data were available for the US from 2000 to 2014, and for Canada and Australia from 2000 to 2012. Injury causes were defined using the International Classification of Diseases, Tenth Revision external cause codes, and were grouped into major causes. Rates were direct-method age-adjusted using the US 2000 projected population as the standard age distribution. US motor vehicle injury mortality rates declined from 2000 to 2014 but remained markedly higher than those of Australia or Canada. In all three countries, fall injury mortality rates increased from 2000 to 2014. US homicide mortality rates declined, but remained higher than those of Australia and Canada. While the US had the lowest suicide rate in 2000, it increased by 24% during 2000-2014, and by 2012 was about 14% higher than that in Australia and Canada. The poisoning mortality rate in the US increased dramatically from 2000 to 2014. Results show marked differences and striking similarities in injury mortality between the countries and within countries over time. The observed trends differed by injury cause category. The substantial differences in injury rates between similarly resourced populations raises important questions about the role of societal-level factors as underlying causes of the differential distribution of injury in our communities.

Road accidents are a serious problem of the modern world. They are one of the main causes of injuries and are the third most frequent cause of death. Every year, about one million people, adults and children, die on the roads and several millions get injured. Mortality rate due to injuries from road accidents amounts to 2.2% of all deaths in the world. The research presents epidemiology of road accidents in the period 2004-2015 with particular emphasis on the key issues of road safety in Poland, related to the dangerous behaviour of road users (disregard toward traffic rules). Between years 2004 and 2015 on Polish roads took place more than 508000 accidents with 53155 fatalities and more then 572000 casualties. Despite the various measures which are taken to improve safety on Polish roads, the number of dead and wounded in the vehicle mishap is still large, and losses borne by society are high. To improve safety on Polish roads, it is necessary to continue multi- action plan to systematically progress in the level of road safety.

Hand injuries are common, contributing up to 30% of accident and emergency (A&E) attendances. The aim of this study was to prospectively analyse the pathological demographics of hand injuries in a level 1 trauma centre with a Hand Trauma Unit and direct A&E links, and compare clinical and intra-operative findings. The null hypothesis was that there would be no differences between clinical and intra-operative findings (100% diagnostic concordance). Data were prospectively collected for referrals during 2012. Referral diagnosis, additional pathologies found on clinical assessment and intra-operative findings were documented on a live database accessible from both the Hand Unit and associated operating theatres. Odds ratios were calculated using SAS. Injuries (1526) were identified in 1308 patients included in the study. Diagnostic concordance between Hand Unit clinical examination and intra-operative findings was 92.5% ± 2.85% (mean ± SEM); this was lower for flexor tendon injuries (56.3%) because a greater number of additional pathologies were found intra-operatively (2.25 ± 0.10). This 'trend' was noted across multiple referral pathologies including phalangeal fractures (1.28 ± 0.02; 82.9%), lacerations (1.33 ± 0.04; 79.1%), extensor tendon injuries (1.30 ± 0.05; 87.8%) and dislocations (1.18 ± 0.05; 87.8%). Odds ratio analysis indicated a relationship between primary referral diagnoses that were more or less likely to be associated with additional injuries (p management of hand trauma. Our findings, coupled with the presented relevant literature reports, lead us to advocate that A&E departments should move towards a system wherein links to specialist hand trauma services are in place; we hereby present useful data for hospitals implementing such services.

2018-04-01

Full Text Available History of present illness: A 27-year-old female sustained an injury to her left hand after she tripped and fell on a vase. She presented to the emergency department (ED complaining of pain over the laceration. Upon examination, patient presented with multiple small abrasions of the medial aspect of the left 5thdigit that are minimally tender. Additionally, she has one 0.5cm linear laceration of the medial aspect of the 5thmetacarpal with severe tenderness in the area and palpable underlying foreign body. Significant findings: Left hand plain radiography demonstrated a subcutaneous foreign body medial to the 5thmetacarpal that is radiopaque, trapezoidal in shape, and measures approximately 11mm x 3mm. Discussion: Laceration repairs are amongst the most common procedures in the emergency department; however, consideration for foreign body is often underdiagnosed. Imaging is performed in only about 11% of all traumatic wounds in the ED.1 Of those injuries relating to the hand that are subsequently imaged, about 15% are found to have a foreign body.2,3 Additionally, it is estimated that foreign bodies are present in 7% to 8.7% of all wounds caused by glass objects.4,5 Glass is among the most common foreign bodies in lacerations, and fortunately they are radiopaque and relatively well visualized radiographically. It has been demonstrated that 2mm glass foreign bodies have a 99% detection rate with radiography, and 1mm glass foreign bodies an 83% detection rate.6 Patient perception of foreign body has a positive predictive value of 31%, making it a poor source in influencing clinical decision-making to obtain wound radiographs.3 Clinicians should have a high suspicion for foreign body in lacerations, particularly those caused by glass, and utilize close physical examination and imaging for evaluation.

The mechanism of dorsal dislocation of the metacarpophalangeal (MCP) joint is with forced hyperextension of the joint and the main structure injured is the volar plate. A simple dislocation can be reduced by closed means whereas a complex dislocation cannot. Care must be taken not to put traction across the joint, which may cause the volar plate to slip into the joint, converting a simple dislocation into a complex dislocation. Volar dislocations are rare and mainly treated nonoperatively. Sagittal band injuries can be treated with extension splinting or surgical management with direct repair or reconstruction. A locked MCP joint can usually be treated with closed manipulation. This article discusses these injuries and management options.

Full Text Available Acute kidney injury (AKI is characterized by an abrupt decline in renal function, resulting in an inability to secrete waste products and maintain electrolyte and water balance, and is associated with high risks of morbidity and mortality. This study retrospectively analyzed clinical data, treatment, and prognosis of 271 hospitalized patients (172 males and 99 females diagnosed with AKI from December, 2008 to December, 2011. In addition, this study explored the association between the cause of AKI and prognosis, severity and treatment of AKI. The severity of AKI was classified according to the Acute Kidney Injury Network (AKIN criteria. Renal recovery was defined as a decrease in a serum creatinine level to the normal value. Prerenal, renal, and postrenal causes accounted for 36.5% (99 patients, 46.5% (126 patients and 17.0% (46 patients, respectively, of the incidence of AKI. Conservative, surgical, and renal replacement treatments were given to 180 (66.4%, 30 (11.1% and 61 patients (22.5%, respectively. The overall recovery rate was 21.0%, and the mortality rate was 19.6%. Levels of Cl(-, Na(+ and carbon dioxide combining power decreased with increasing severity of AKI. Cause and treatment were significantly associated with AKI prognosis. Likewise, the severity of AKI was significantly associated with cause, treatment and prognosis. Multivariate logistic regression analysis found that respiratory injury and multiple organ dysfunction syndrome (MODS were associated with AKI patient death. Cause, treatment and AKIN stage are associated with the prognosis of AKI. Respiratory injury and MODS are prognostic factors for death of AKI patients.

Full Text Available Drug-induced liver injury (DILI is the most common cause of acute liver failure in the Unites States and accounts for 10% of acute hepatitis cases. We report the only known case of diphenhydramine-induced acute liver injury in the absence of concomitant medications. A 28-year-old man with history of 13/14-chromosomal translocation presented with fevers, vomiting, and jaundice. Aspartate-aminotransferase and alanine-aminotransferase levels peaked above 20,000 IU/L and 5,000 IU/L, respectively. He developed coagulopathy but without altered mental status. Patient reported taking up to 400 mg diphenhydramine nightly, without concomitant acetaminophen, for insomnia. He denied taking other medications, supplements, antibiotics, and herbals. A thorough workup of liver injury ruled out viral hepatitis (including A, B, C, and E, autoimmune, toxic, ischemic, and metabolic etiologies including Wilson’s disease. A liver biopsy was consistent with DILI without evidence of iron or copper deposition. Diphenhydramine was determined to be the likely culprit. This is the first reported case of diphenhydramine-induced liver injury without concomitant use of acetaminophen.

Our research group has described both morphological and electrophysiological changes in motor cortex pyramidal neurons associated with contralateral facial nerve injury in rats. However, little is known about those neural changes, which occur together with changes in surrounding glial cells. To characterize the effect of the unilateral facial nerve injury on microglial proliferation and activation in the primary motor cortex. We performed immunohistochemical experiments in order to detect microglial cells in brain tissue of rats with unilateral facial nerve lesion sacrificed at different times after the injury. We caused two types of lesions: reversible (by crushing, which allows functional recovery), and irreversible (by section, which produces permanent paralysis). We compared the brain tissues of control animals (without surgical intervention) and sham-operated animals with animals with lesions sacrificed at 1, 3, 7, 21 or 35 days after the injury. In primary motor cortex, the microglial cells of irreversibly injured animals showed proliferation and activation between three and seven days post-lesion. The proliferation of microglial cells in reversibly injured animals was significant only three days after the lesion. Facial nerve injury causes changes in microglial cells in the primary motor cortex. These modifications could be involved in the generation of morphological and electrophysiological changes previously described in the pyramidal neurons of primary motor cortex that command facial movements.

Full Text Available Inadequate ventilator settings may cause overwhelming inflammatory responses associated with ventilator-induced lung injury (VILI in patients with acute respiratory distress syndrome (ARDS. Here, we examined potential benefits of glutamine (GLN on a two-hit model for VILI after acid aspiration-induced lung injury in rats. Rats were intratracheally challenged with hydrochloric acid as a first hit to induce lung inflammation, then randomly received intravenous GLN or lactated Ringer’s solution (vehicle control thirty min before different ventilator strategies. Rats were then randomized to receive mechanical ventilation as a second hit with a high tidal volume (TV of 15 mL/kg and zero positive end-expiratory pressure (PEEP or a low TV of 6 mL/kg with PEEP of 5 cm H2O. We evaluated lung oxygenation, inflammation, mechanics, and histology. After ventilator use for 4 h, high TV resulted in greater lung injury physiologic and biologic indices. Compared with vehicle treated rats, GLN administration attenuated lung injury, with improved oxygenation and static compliance, and decreased respiratory elastance, lung edema, extended lung destruction (lung injury scores and lung histology, neutrophil recruitment in the lung, and cytokine production. Thus, GLN administration improved the physiologic and biologic profiles of this experimental model of VILI based on the two-hit theory.

Data outlining the mortality and the causes of death in patients with type 1 myocardial infarction, type 2 myocardial infarction, and those with myocardial injury are limited. During a 1-year period from January 2010 to January 2011, all hospitalized patients who had cardiac troponin I measured on clinical indication were prospectively studied. Patients with at least one cardiac troponin I value >30 ng/L underwent case ascertainment and individual evaluation by an experienced adjudication committee. Patients were classified as having type 1 myocardial infarction, type 2 myocardial infarction, or myocardial injury according to the criteria of the universal definition of myocardial infarction. Follow-up was ensured until December 31, 2014. Data on mortality and causes of death were obtained from the Danish Civil Registration System and the Danish Register of Causes of Death. Overall, 3762 consecutive patients were followed for a mean of 3.2 years (interquartile range 1.3-3.6 years). All-cause mortality differed significantly among categories: Type 1 myocardial infarction 31.7%, type 2 myocardial infarction 62.2%, myocardial injury 58.7%, and 22.2% in patients with nonelevated troponin values (log-rank test; P causes, vs 42.6% in patients with type 2 myocardial infarction (P = .015) and 41.2% in those with myocardial injury (P causes of death did not differ substantially between patients with type 2 myocardial infarction and those with myocardial injury. Patients with type 2 myocardial infarction and myocardial injury exhibit a significantly higher long-term mortality compared with patients with type 1 myocardial infarction . However, most patients with type 1 myocardial infarction die from cardiovascular causes in contrast to patients with type 2 myocardial infarction and myocardial injury, in whom noncardiovascular causes of death predominate.

Paparone, Pamela

2013-01-01

The motorized mobility scooter (MMS) provides considerable benefits to patients with mobility limitations. Nevertheless, safety concerns related to MMS use are an issue. With increased use because of increased life expectancy and chronic illness, there are a growing number of reports of MMS-related injuries, ranging from lacerations and contusions to fatalities. Comorbidities may also exacerbate wound care. Prevention of these injuries is greatly needed. The author presents 5 patients with lower-extremity ulceration caused by MMS injuries. To prevent these injuries, health care providers must carefully evaluate and monitor patients. Clinicians and MMS manufacturers also need to educate and train patients on the safe use of MMS devices, including the regular use of footwear. Copyright © 2013 Mosby, Inc. All rights reserved.

Correction of severe postburn claw hand.

Davami, Babak; Pourkhameneh, Golnar

2011-12-01

Burn scar contractures are perhaps the most frequent and most frustrating sequelae of thermal injuries to the hand. Unfortunately, stiffness occurs in the burned hand quickly. A week of neglect in the burned hand can lead to digital malpositioning and distortion that may be difficult to correct. The dorsal contracture is the most common of all the complications of the burned hand. It is the result of damage to the thin dorsal skin and scant subcutaneous tissue, which offers little protection to the deeper structures. Consequently, these injuries are deep resulting in a spectrum of deformities that has remained the bane of reconstructive surgery. Flap coverage will be required in the event of exposure of joints and tendons with absent paratenons. Multiple different flap types are available to treat complex severe postburn hand contractures. In our center, which is the largest regional burn center in northwest Iran, we have considerable experience in the treatment of thermal hand injuries. Between 2005 and 2010, we treated 53 consecutive patients with 65 severe postburn hand deformities. There were 35 men and 18 women with a mean age of 35±3 years. Flame injury was the inciting traumatic event in each patient. The severity of original injury and inadequate early treatment resulted in all of the fingers developing a severe extension contracture with scarred and adherent extensor tendons and subluxed metacarpophalangeal joints. In 36 cases, the injury was in the patients' dominant hand. We first incised the dorsal aspect of the contracted hands where there was maximum tension, then tenolysed the extensor tendons and released the volar capsules, collateral ligaments, and volar plate in all cases. In 30 cases, we also tenolysed the flexor tendons. We reduced the subluxed metacarpophalangeal joints and fixed them with Kirschner wires in 70 to 90 degrees flexion. Then, we planned and performed axial groin flaps to reconstruct the defects in all of them. In all of these

Full Text Available Purpose. Hand infections are common, usually resulting from an untreated injury. In this retrospective study, we report on hand infection cases needing surgical drainage in order to assess patient demographics, causation of infection, clinical course, and clinical management.Methods. Medical records of patients presenting with hand infections, excluding post-surgical infections, treated with incision and debridement over a one-year period were reviewed. Patient demographics; past medical history; infection site(s and causation; intervals between onset of infection, hospital admission, surgical intervention and days of hospitalization; gram stains and cultures; choice of antibiotics; complications; and outcomes were reviewed.Results. Most infections were caused by laceration and the most common site of infection was the palm or dorsum of the hand. Mean length of hospitalization was 6 days. Methicillin-resistant Staphylococcus aureus, beta-hemolytic Streptococcus and methicillin-susceptible Staphylococcus aureus were the most commonly cultured microorganisms. Cephalosporins, clindamycin, amoxicillin/clavulanate, penicillin, vancomycin, and trimethoprim/sulfamethoxazole were major antibiotic choices. Amputations and contracture were the primary complications.Conclusions. Surgery along with medical management were key to treatment and most soft tissue infections resolved without further complications. With prompt and appropriate care, most hand infection patients can achieve full resolution of their infection.

We evaluated demographic and occupational features of patients with phalangeal fractures of the hand, etiologies and types of injuries, and the results of rehabilitation. The study included 91 fingers of 62 patients (54 males, 8 females; mean age 28+/-13 years; range 4 to 59 years) who were referred to our hand rehabilitation unit for phalangeal fractures. Demographic features, the cause and localization of injury, the type of surgery, time from surgery to rehabilitation, and the follow-up period were determined. At the end of rehabilitation, range of motion (ROM) of the phalangeal joint and total ROM of the injured fingers were assessed using the Strickland-Glogovac rating system. A great majority of injuries were caused by work accidents, followed by sport injuries and falls occurring in students. Sixty patients (96.8%) were right-handed. The fractures occurred in the dominant hand in 29 patients (46.8%). The majority of patients (n=45) were primary school graduates. The most common mechanism of injury was accidents related to heavy work machinery (n=18). The most commonly injured finger and the phalanx were the third finger (n=25, 27.5%) and the proximal phalanx (n=59, 56.7%), respectively. Only 27 patients (43.6%) had a sufficient follow-up with a mean of 79.7+/-46.6 days (range 30 to 254 days). Following rehabilitation, the mean ROM and the total ROM were 45.0+/-22.9 degrees and 63.3+/-16.1 degrees for the injured joint and the thumb, and 31.3+/-22.5 degrees and 122+/-60.3 degrees for the injured joint and the other fingers, respectively. Our data provide important insight into appropriate treatment and rehabilitation of phalangeal fractures, in particular, shortcomings in the treatment and follow-up.

Traumatic brain injury (TBI) causes brain dysfunction in many patients. However, some patients have severe brain dysfunction but display no abnormalities on magnetic resonance imaging (MRI). There have been some reports of hypometabolism even in such patients. The purpose of this study was to investigate the relationship between metabolic abnormality and loss of neuronal integrity in TBI patients with some symptoms but without MRI abnormalities. The study population comprised ten patients with TBI and ten normal volunteers. All of the patients were examined at least 1 year after the injury. 15 O-labelled gas PET and [ 11 C]flumazenil (FMZ) positron emission tomography (PET) were carried out. The cerebral metabolic rate of oxygen (CMRO 2 ) and binding potential (BP) images of FMZ were calculated. Axial T2WI, T2*WI and FLAIR images were obtained. Coronal images were added in some cases. All of the patients had normal MRI findings, and all showed areas with abnormally low CMRO 2 . Low uptake on BP images was observed in six patients (60%). No lesions that showed low uptake on BP images were without low CMRO 2 . On the other hand, there were 14 lesions with low CMRO 2 but without BP abnormalities. These results indicate that there are metabolic abnormalities in TBI patients with some symptoms after brain injury but without abnormalities on MRI. Some of the hypometabolic lesions showed low BP, indicating a loss of neuronal integrity. Thus, FMZ PET may have potential to distinguish hypometabolism caused by neuronal loss from that caused by other factors. (orig.)

Case reports do not consider the population which is injured and therefore are inappropriate for finding causal relationships. A review of three epidemiological studies, which take the population into account, showed that the only reasonably well-established cause of running injuries is the number of miles run per week.

Collaterals lessen tissue injury in occlusive disease. However, aging causes progressive decline in their number and smaller diameters in those that remain (collateral rarefaction), beginning at 16 months of age in mice (i.e., middle age), and worse ischemic injury-effects that are accelerated in even 3-month-old eNOS(-/-) mice. These findings have found indirect support in recent human studies. We sought to determine whether other cardiovascular risk factors (CVRFs) associated with endothelial dysfunction cause collateral rarefaction, investigate possible mechanisms, and test strategies for prevention. Mice with nine different models of CVRFs of 4-12 months of age were assessed for number and diameter of native collaterals in skeletal muscle and brain and for collateral-dependent perfusion and ischemic injury after arterial occlusion. Hypertension caused collateral rarefaction whose severity increased with duration and level of hypertension, accompanied by greater hindlimb ischemia and cerebral infarct volume. Chronic treatment of wild-type mice with L-N (G)-nitro-arginine methylester caused similar rarefaction and worse ischemic injury which were not prevented by lowering arterial pressure with hydralazine. Metabolic syndrome, hypercholesterolemia, diabetes mellitus, and obesity also caused collateral rarefaction. Neither chronic statin treatment nor exercise training lessened hypertension-induced rarefaction. Chronic CVRF presence caused collateral rarefaction and worse ischemic injury, even at relatively young ages. Rarefaction was associated with increased proliferation rate of collateral endothelial cells, effects that may promote accelerated endothelial cell senescence.

Functional Extravehicular Mobility Units (EMUs) with high precision gloves are essential for the success of Extravehicular Activity (EVA). Previous research done at NASA has shown that total strength capabilities and performance are reduced when wearing a pressurized EMU. The goal of this project was to characterize the human-space suit glove interaction and assess the risk of injury during common EVA hand manipulation tasks, including pushing, pinching and gripping objects. A custom third generation sensor garment was designed to incorporate a combination of sensors, including force sensitive resistors, strain gauge sensors, and shear force sensors. The combination of sensors was used to measure the forces acting on the finger nails, finger pads, finger tips, as well as the knuckle joints. In addition to measuring the forces, data was collected on the temperature, humidity, skin conductance, and blood perfusion of the hands. Testing compared both the Phase VI and Series 4000 glove against an ungloved condition. The ungloved test was performed wearing the sensor garment only. The project outcomes identified critical landmarks that experienced higher workloads and are more likely to suffer injuries. These critical landmarks varied as a function of space suit glove and task performed. The results showed that less forces were acting on the hands while wearing the Phase VI glove as compared to wearing the Series 4000 glove. Based on our findings, the engineering division can utilize these methods for optimizing the current space suit glove and designing next generation gloves to prevent injuries and optimize hand mobility and comfort.

This study compares surgical techniques and surgeon's standing position during laparoscopic cholecystectomy (LC), investigating each with respect to surgeons' learning, performance, and ergonomics. Little homogeneity exists in LC performance and training. Variations in standing position (side-standing technique vs. between-standing technique) and hand technique (one-handed vs. two-handed) exist. Thirty-two LC procedures performed on a virtual reality simulator were video-recorded and analyzed. Each subject performed four different procedures: one-handed/side-standing, one-handed/between-standing, two-handed/side-standing, and two-handed/between-standing. Physical ergonomics were evaluated using Rapid Upper Limb Assessment (RULA). Mental workload assessment was acquired with the National Aeronautics and Space Administration-Task Load Index (NASA-TLX). Virtual reality (VR) simulator-generated performance evaluation and a subjective survey were analyzed. RULA scores were consistently lower (indicating better ergonomics) for the between-standing technique and higher (indicating worse ergonomics) for the side-standing technique, regardless of whether one- or two-handed. Anatomical scores overall showed side-standing to have a detrimental effect on the upper arms and trunk. The NASA-TLX showed significant association between the side-standing position and high physical demand, effort, and frustration (p<0.05). The two-handed technique in the side-standing position required more effort than the one-handed (p<0.05). No difference in operative time or complication rate was demonstrated among the four procedures. The two-handed/between-standing method was chosen as the best procedure to teach and standardize. Laparoscopic cholecystectomy poses a risk of physical injury to the surgeon. As LC is currently commonly performed in the United States, the left side-standing position may lead to increased physical demand and effort, resulting in ergonomically unsound conditions for

Full Text Available Ballistic injuries of oral and maxillofacial region are usually fatal due to close propinquity with the vital structures. The severity of injury depends on the caliber of the weapon used and distance from which the patient is shot. The preliminary care of facial ballistic wounds strictly adheres to the basics of trauma resuscitation. Early and appropriate surgical management has proved to be influential on the final outcome and esthetic result. Treatment of facial gunshot wounds should be planned and carried out carefully to avoid esthetic complications. It takes even multiple-staged corrections to achieve the targeted functional and esthetic treatment plan. Prevention and control of infection is one of the most important goals to achieve the success of the treatment. Herewith, we present a case of facial gunshot injury with fractures in the orbital floor, medial wall maxillary sinus, and buttress of the zygomatic bone causing deficit, which was successfully managed by surgical reconstruction.

Pseudo-aneurysm of the anterior tibial artery, a rare cause of ankle swelling following a sports injury

Directory of Open Access Journals (Sweden)

McAteer Eamon

2005-10-01

Full Text Available Abstract Background Ankle pain and swelling following sports injuries are common presenting complaints to the accident and emergency department. Frequently these are diagnosed as musculoskeletal injuries, even when no definitive cause is found. Vascular injuries following trauma are uncommon and are an extremely rare cause of ankle swelling and pain. These injuries may however be limb threatening and are important to diagnose early, in order that appropriate treatment can be delivered. We highlight the steps to diagnosis of these injuries, and methods of managing these injuries. It is important for clinicians to be aware of the potential for this injury in patients with seemingly innocuous trauma from sports injuries, who have significant ankle pain and swelling. Case presentation A young, professional sportsman presented with a swollen, painful ankle after an innocuous hyper-plantar flexion injury whilst playing football, which was initially diagnosed as a ligamentous injury after no bony injury was revealed on X-Ray. He returned 2 days later with a large ulcer at the lateral malleolus and further investigation by duplex ultrasound and transfemoral arteriogram revealed a Pseudo-Aneurysm of the Anterior Tibial Artery. This was initially managed with percutaneous injection of thrombin, and later open surgery to ligate the feeding vessel. The patient recovered fully and was able to return to recreational sport. Conclusion Vascular injuries remain a rare cause of ankle pain and swelling following sports injuries, however it is important to consider these injuries when no definite musculo-skeletal cause is found. Ultrasound duplex and Transfemoral arteriogram are appropriate, sensitive modalities for investigation, and may allow novel treatment to be directed percutaneously. Early diagnosis and intervention are essential for the successful outcome in these patients.

Overview of causes and costs of injuries in Massachusetts: a methodology for analysis of state data.

1995-01-01

Massachusetts has developed the first State profile of the causes and costs of injury based on the national study, "Cost of Injury in the United States: A Report to Congress." Incidence of fatal injuries is based on Massachusetts data; nonfatal hospitalized injuries, on Massachusetts age and sex rates and U.S. cause data; and nonhospitalized injuries, on U.S. rates applied to Massachusetts census data. Lifetime costs per injured person are based on national data adjusted for higher personal health care expenditures and for higher mean annual earnings in Massachusetts. The estimated total lifetime cost for the 1.4 million injuries that occurred in 1989 is $4.4 billion--$1.7 billion for health care and $2.7 billion for lost earnings. Injuries attributed to motor vehicles and falls account for more than half of the total cost. The other cause categories are poisonings, fire-burns, firearms, drowings-near drownings, and other. For every person who dies from an injury, 17 people are hospitalized, and an estimated 535 people require outpatient treatment, consultation, or restricted activity. Development of a State-based cost report can be useful in monitoring the contribution of injuries to health status and in planning effective injury prevention strategies in a community-based health care system. The methodology described in this paper can be replicated by other States through accessing their State-specific mortality and hospital discharge data bases. PMID:7610211

Mountain biking injuries in children and adolescents.

Aleman, Kylee B; Meyers, Michael C

2010-01-01

Over the last decade, the sport of mountain biking has experienced extensive growth in youth participation. Due to the unpredictable nature of outdoor sport, a lack of rider awareness and increased participation, the number of injuries has unnecessarily increased. Many believe that the actual incidence of trauma in this sport is underestimated and is just the 'tip of the iceberg'. The most common mechanism of injury is usually attributed to downhill riding and forward falling. Although rare, this type of fall can result in serious cranial and thoraco-abdominal trauma. Head and neck trauma continue to be documented, often resulting in concussions and the possibility of permanent neurological sequelae. Upper limb injuries range from minor dermal abrasions, contusions and muscular strains to complex particular fracture dislocations. These are caused by attempting to arrest the face with an outstretched hand, leading to additional direct injury. Common overuse injuries include repeated compression from the handlebars and vibration leading to neurovascular complications in the hands. Along with reports of blunt abdominal trauma and lumbar muscle strains, lower extremity injuries may include various hip/pelvic/groin contusions, patellofemoral inflammation, and various muscle strains. The primary causes of mountain biking injuries in children and adolescents include overuse, excessive fatigue, age, level of experience, and inappropriate or improperly adjusted equipment. Additional factors contributing to trauma among this age group involve musculoskeletal immaturity, collisions and falls, excessive speed, environmental conditions, conditioning and fitness status of the rider, nonconservative behavioural patterns, and inadequate medical care. The limited available data restrict the identification and understanding of specific paediatric mountain biking injuries and injury mechanisms.

Hand injuries are very common in sports, such as skiing and ball sports. One of the major reasons causing hand and finger deformity is due to ligament and tendon injury. The aim of this study was to investigate if the high-resolution 3T magnetic resonance imaging (MRI) can demonstrate the complex anatomy of the fingers and thumb, especially the tendons and ligaments, and provide the accurate diagnosis of clinically important fingers and thumbs deformity due to ligamentous and tendinous injuries during sport activities. Sixteen fresh un-embalmed cadaveric hands were harvested from eight cadavers. A total of 20 healthy volunteers' hands and 44 patients with fingers or thumb deformity due to sports-related injuries were included in this study. All subjects had MR examination with T1-weighted images and proton density-weighted imaging with fat suppression (PD FS) in axial, coronal, and sagittal plane, respectively. Subsequently, all 16 cadaveric hands were sliced into 2-mm thick slab with a band saw (six in coronal plane, six in sagittal plane, and four in axial plane). The correlation of anatomic sections and the MRI characteristics of tendons of fingers and the ulnar collateral ligament (UCL) at the metacarpal phalangeal joint (MCPJ) of thumb between 20 healthy volunteers and 44 patients (confirmed by surgery) were analyzed. The normal ligaments and tendons in 16 cadaveric hands and 20 volunteers' hands showed uniform low-signal intensity on all the sequences of the MRI. Among 44 patients with tendinous and ligamentous injuries in the fingers or thumb, 12 cases with UCL injury at MCPJ of the thumb (Stener lesion = 8 and non-Stener lesion = 4), 6 cases with the central slip injury, 12 cases with terminal tendon injury, and 14 cases with flexor digitorum profundus injury. The ligaments and tendons disruption manifested as increased signal intensity and poor definition, discontinuity, and heterogeneous signal intensity of the involved ligaments and tendons. Sports

Your hands are precious, look after them!

CERN Multimedia

With their 27 bones, 33 muscles and 22 joints, hands are the most complicated and at the same time the most useful parts of the body. Without them, we would not be able to grip things between our fingers, pick them up, turn them, lift them, hold them or handle them. Due to this very usefulness, however, they are more prone to injury than any other part of the body. This year, over 30% of CERN's industrial accidents involved hand injuries. Many of these accidents could have been avoided if the people concerned had worn suitable gloves or, quite simply, made proper use of tools adapted to the work they were doing. 1. Mechanically sustained injuries Most hand injuries are mechanically sustained. - Cuts and pricks often occur during the use or handling of sharp objects and tools. The Medical Service has treated many patients with cuts received when handling iron plates or when using cutters without taking adequate precautions. Such injuries range from superficial cuts to deep wounds with severed tendons or bl...

We present the case of a patient who sustained a penetrating injury to the chest caused by an attenuated energy rubber bullet and review the literature on thoracic injuries caused by plastic and rubber "less-lethal" munitions. The patient of this report underwent a right thoracotomy to extract the projectile as well as a wedge resection of the injured lung parenchyma. This case demonstrates that even supposedly safe riot control munition fired at close range, at the torso, can provoke serious injury. Therefore a thorough investigation and close clinical supervision are justified.

Importance of external cause coding for injury surveillance: lessons from assessment of overexertion injuries among U.S. Army soldiers in 2014.

Injuries are a barrier to military medical readiness, and overexertion has historically been a leading mechanism of injury among active duty U.S. Army soldiers. Details are needed to inform prevention planning. The Defense Medical Surveillance System (DMSS) was queried for unique medical encounters among active duty Army soldiers consistent with the military injury definition and assigned an overexertion external cause code (ICD-9: E927.0-E927.9) in 2014 (n=21,891). Most (99.7%) were outpatient visits and 60% were attributed specifically to sudden strenuous movement. Among the 41% (n=9,061) of visits with an activity code (ICD-9: E001-E030), running was the most common activity (n=2,891, 32%); among the 19% (n=4,190) with a place of occurrence code (ICD-9: E849.0-E849.9), the leading location was recreation/sports facilities (n=1,332, 32%). External cause codes provide essential details, but the data represented less than 4% of all injury-related medical encounters among U.S. Army soldiers in 2014. Efforts to improve external cause coding are needed, and could be aligned with training on and enforcement of ICD-10 coding guidelines throughout the Military Health System.

Gross Domestic Product (GDP) and unemployment has a strong documented impact on injury mortality. The aim of our study is to investigate the relationship of GDP per capita and unemployment with gender- and cause-specific injury mortalities in the member nations of Organization for Economic Cooperation and Development (OECD). Country-based data on injury mortality per 100,000 population, including males and females aged 1-74, for the 4 year period 1996-1999, were gathered from the World Health Organization's Statistical Information System. We selected fourteen cause-specific injury mortalities. Data on GDP, unemployment rate and population growth were taken from World Development Indicators. GDP and unemployment rate per 100 separately were regressed on total and cause-specific injury mortality rate per 100,000 for males and females. Overall in the OECD countries, GDP per capita increased 12.5% during 1996-1999 (P = 0.03) where as unemployment rate decreased by 12.3% (P = 0.05). Among males, most cause-specific injury mortality rates decreased with increasing GDP except motor vehicle traffic crashes (MTC) that increased with increasing GDP (coefficient = 0.75; P GDP (coefficient = 0.31; P = 0.04). When we modeled cause-specific injury mortality rates with unemployment, injuries due to firearm missiles (coefficient = 0.53; P GDP is more related to cause-specific injury mortality than unemployment. Injury mortality does not relate similarly to each diagnosis-specific cause among males and females. Further research on causation with more predictors is needed.

The causes of blunt ocular trauma are many and diverse. We present two cases of ocular injury caused by an unusual form of weapon called a "Johnny Popper". There follows a theoretical and experimental evaluation of the velocity of the projectiles fired by this device. A Johnny Popper was constructed under expert guidance. The elastic properties of the device were measured and this allowed calculation of a theoretical exit velocity of the projectiles fired. The weapon was subsequently fired under test conditions which permitted the exit velocity of the projectiles fired to be measured directly. The theoretical velocity of the projectiles was calculated as 80 ms-1 and the experimentally measured velocity was 57 ms-1. Johnny Poppers are a previously undescribed and unique form of home made weapon. They are intended for playful mischief, but have the potential to cause serious ocular trauma.

The construction sector is associated with various accidents and fatal injuries. These occupational accidents are caused by numerous factors, such as lack of supervision; lack of adherence to safe work technique; failure to wear personal protective equipment; and failure to comply with the safe use of tools, vehicles, and machines. Using 2013–2016 secondary data from the Department of Occupational Safety and Health and Social Security Organization, this study conducted a descriptive exploration survey to identify common fatal occupational injuries associated with the Malaysian construction sector, as well as their causes and accidental agents. Results indicated that construction, followed by manufacturing, agriculture, forestry, logging, and fishery, are the riskiest job sectors in Malaysia. The highest incidences of occupational casualties were reported in Sarawak, Johor, and Selangor. These states accounted for approximately 13.33% to 18.18% of all cases of fatal occupational accidents. In these states, the lack of safety and health regulations and poor execution of risk management increased the risk of occupational accidents. Falls from heights accounted for 46.28% of fatal occupational injuries. Furthermore, being crushed by objects, materials, or vehicles accounted for 9.09% to 17.36% of fatal occupational injuries. Substandard work environment and transportation and lifting equipment, such as scaffolds, are primary accidental agents. Results of this study could enhance the knowledge and awareness of construction workers and management of job-related injuries to decrease the incidence of fatal occupational accidents.

The diagnostics of thermal injuries caused by inflammation of combustible fluids should be based on the comprehensive assessment of the results of examination of the scene of the accident, autopsy studies, forensic chemical expertise, and analysis of the circumstances of the case and/or medical documentation. Special attention should be given to the choice of adequate methods for taking samples to be used in forensic chemical studies. The assessment of thermal injuries caused by inflammation of combustible fluids must take into consideration the time and conditions under which they were inflicted (e.g. closed or open space, vertical or horizontal position, etc.).

Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity. This study linked different data sources to measure the numbers of deaths and serious injuries and to estimate the percentage of corrections regarding the underlying cause of death, cause of injury, and the severity injury in victims in matched pairs from record linkage in five representative state capitals of the five macro-regions of Brazil. This cross-sectional, population-based study used data from the Hospital Information System (HIS), Mortality Information System (MIS), and Police Road Traffic database of Belo Horizonte, Campo Grande, Curitiba, Palmas, and Teresina, for the year 2013 for Teresina, and 2012 for the other capitals. RecLink III was used to perform probabilistic record linkage by identifying matched pairs to calculate the global correction percentage of the underlying cause of death, the circumstance that caused the road traffic injury, and the injury severity of the victims in the police database. There was a change in the cause of injury in the HIS, with an overall percentage of correction estimated at 24.4% for Belo Horizonte, 96.9% for Campo Grande, 100.0% for Palmas, and 33.2% for Teresina. The overall percentages of correction of the underlying cause of death in the MIS were 29.9%, 11.9%, 4.2%, and 33.5% for Belo Horizonte, Campo Grande, Curitiba, and Teresina, respectively. The correction of the classification of injury severity in police database were 100.0% for Belo

To learn more about the causes of nonfatal construction worker injuries, and to identify injury cases for further work-site investigations or prevention programs, an emergency department-based surveillance program was established. Construction workers with work-related injuries or illnesses were identified by reviewing the medical records of all patients treated at the George Washington University Emergency Department between November 1, 1990 and November 31, 1992. Information regarding the worker, the injury, and the injury circumstances were abstracted from medical records. Information was obtained on 592 injured construction workers from numerous trades. Lacerations were the most commonly treated injuries among these workers, followed by strains and sprains, contusions, and eye injuries. Injuries were most commonly caused by sharp objects (n = 155, 26%), falls (n = 106, 18%), and falling objects (n = 70, 12%). Thirty-five percent of injuries were to the hands, wrists, or fingers. Among the twenty-eight injuries severe enough to require hospital admission, eighteen (64%) were caused by falls. Laborers and Hispanic workers were overrepresented among these severe cases. Emergency Department records were a useful surveillance tool for the initial identification and description of work-related injuries. Although E codes were not that useful for formulating prevention strategies, detailed review of injury circumstances from Emergency Department records was valuable and has helped to establish priorities for prevention activities.

To identify those risk factors that have the greatest impact on the incidence of head and neck injuries in international football. A case-control study of players sustaining head and neck injuries during 20 FIFA tournaments (men and women) from 1998 to 2004. Video recordings of incidents were used to identify a range of parameters associated with the incidents. Team physicians provided medical reports describing the nature of each injury. chi2 tests (pvideo sequences. The commonest injuries were contusions (53%), lacerations (20%), and concussions (11%). The incidence of all head and neck injuries was 12.5/1000 player hours (men 12.8, women 11.5) and 3.7 for lost-time injuries (men 3.5, women 4.1). The commonest causes of injury involved aerial challenges (55%) and the use of the upper extremity (33%) or head (30%). The unfair use of the upper extremity was significantly more likely to cause an injury than any other player action. Only one injury (a neck muscle strain) occurred as a result of heading the ball throughout the 20 tournaments equivalent to 0.05 injuries/1000 player hours. Players' actions most likely to cause a head or neck injury were the use of the upper extremity or the head but in the majority of cases these challenges were deemed to be fair and within the laws of the game.

A data acquisition from the medical sector may give one important view of the burden on the society caused by vehicle related injuries. The official police-reported statistics may only reflect a part of all vehicle-related injured seeking medical attention. The aim is to provide a comprehensive picture of the burden of vehicle related injuries on the medical sector (2013), and to compare with official police-reported statistics and the development year 2000-2013. The data set includes 1085 injured from the Injury Data Base at Umeå University Hospital's catchment area with 148,500 inhabitants in 2013. Bicyclists were the most frequently injured (54%). One-third had non-minor (MAIS2+) injuries, and bicyclists accounted for 58% of the 1071 hospital bed days for all vehicle-related injuries. Car occupants represented 23% of all injured, and only 9% had MAIS2+ injuries. They accounted for 17% of the hospital bed days. Motorized two wheel vehicle riders represented 11% of the injured and 39% had MAIS2+ injuries and they occupied 11% of the hospital bed days. Of the 1085 medically treated persons, 767 were injured in public traffic areas, and, therefore, should be included in the official police statistics; however, only a third (232) of them were reported by the police. The annual injury rate had not changed during 2000-2013 for bicyclists, motor-cycle riders, pedestrians or snowmobile riders. However, for passenger car occupants a decrease was observed after 2008, and for mopedists the injury rate was halved after 2009 when a licensing regulation was introduced. The Swedish traffic injury reducing strategy Vision Zero, may have contributed to the reduction of injured car occupants and moped riders. The official police-reported statistics was a biased data source for vehicle related injuries and the total number medically treated was in total five times higher. Bicyclists caused the heaviest burden on the medical sector; consequently, they need to be prioritized in

To analyze the incidence of ACL and meniscal injuries in a population of recreational and elite athletes from Brazil and the relation of these injuries with their sports activities. This was a prospective observational study of 240 patients with ACL and/or meniscal injuries submitted to surgical treatment. Data of patients and sport modality, as well as Tegner score were registered in the first clinical evaluation. The patients were divided into three groups: (1) isolated rupture of the ACL; (2) ACL injury associated with meniscal injury; (3) isolated menisci injury. The majority of the patients belonged to group 1 (44.58%), followed by group 2 (30.2%) and 3 (25%). Most patients were soccer players. The mean time from sport practice to injury in group 1 was 17.81 years. In group 2, it was 17.3 years, and in group 3, 26.91 years. Soccer athletes presented ACL injury in 0.523/1000 h of practice and meniscal injury in 0.448/1000 h of practice. Before the injury, the mean Tegner score obtained for groups 1, 2, and 3 were 7.18, 7.34, and 6.53, respectively. After knee injury, those values were 3.07, 3.18, and 2.87, respectively. Soccer was the sport that caused the majority of lesions, regardless the group. Furthermore, patients from groups 1 and 2 had less time of practice prior to the injury (17.81 and 17.3 years) than the patients of group 3 (26.91 years). Women presented a higher risk to develop ACL and meniscal injuries in 1000 h of game/practice. Running, volleyball, and weightlifting are in ascending order of risk for ACL and/or meniscal injury. Regarding the return to sport practice, the efficiency of all athletes was impaired because of the injury.

Full Text Available Injuries caused by venomous animals reported by the agricultural workers from the municipality of Cuité, Curimataú region of Paraiba State, Northeast of Brazil, and the practices of folk medicine which they use to treat these cases were studied in this work from June to August 2010. The farmers studied aged from 11 to 90 years. The number of people who reported cases of injury by these animals in their families was high (89.3%. Scorpions, wasps, bees and snakes were the most cited and the extremities of the body (hands, feet, legs and head were the most affected. The practice of folk medicine to treat these injuries includes various procedures ranging from ritualistic treatments, use of animals or parts of them, and some herbal preparations. The folk treatment was reported as effective by most of the workers injured (63.9%. Body parts of dead snakes are used in various zootherapic treatments. In the imaginary of the agricultural workers the venomous animals are considered hazardous (48.7% or disgusting (11.3%, and several parts of such animals as the rattle, bee sting or snake leather are used as amulet. Several legends have also been reported about snakes, scorpions and bees. The need for educational activities that aim to clarify these workers about the dangers of such practices is urgent.

Penetrating injury to the chest by an attenuated energy projectile: a case report and literature review of thoracic injuries caused by "less-lethal" munitions

Full Text Available Abstract We present the case of a patient who sustained a penetrating injury to the chest caused by an attenuated energy rubber bullet and review the literature on thoracic injuries caused by plastic and rubber "less-lethal" munitions. The patient of this report underwent a right thoracotomy to extract the projectile as well as a wedge resection of the injured lung parenchyma. This case demonstrates that even supposedly safe riot control munition fired at close range, at the torso, can provoke serious injury. Therefore a thorough investigation and close clinical supervision are justified.

Management of a Low-Energy Penetrating Brain Injury Caused by a Nail

Full Text Available Low-energy penetrating nail injury to the brain is an extremely rare neurosurgical emergency. The most common cause of nail gun injury is work related accidents; other causes result from accidental firing of a nail gun, suicide attempts by firing nail guns into the brain, and bomb blasts containing pieces of nails. Neurosurgical treatment performed by craniotomy still seems to be the safest one; there are reports of complications such as subdural hematoma and intraparenchymal hemorrhages following the blind removal of foreign bodies leading to suggestions that all penetrating foreign bodies should be removed under direct vision. We report a rarely described neurosurgical approach for removal of a penetrating nail from the brain and skull without evidence of associated hematoma and other brain lesions.

Recently injury has become a major world-wide health problem. But studies in Korea about injuries were very few. Thus, this study was conducted to analyze the trend of major injuries from 1991 to 2006 and to provide basic data for preventing injuries. This study was based on the National Statistical Office data from 1991 to 2006 and calculated to estimate the burden of major injuries by using the standard expected years of life lost (SEYLL) and total lost earnings equation. For transport accidents, mortality, SEYLL and total lost earnings were increased from 1991 to 1996 and decreased from 2000 to 2006. On the other hand, for suicides, these were increased gradually. Since 2003, falls were included in ten leading causes of death. This study showed that injury causes major social and economical losses. We could reduce injury related premature death through active interest in injury prevention program.

Sim, Taeyong; Jang, Dong-Jin; Oh, Euichaul

2014-01-01

A new methodological approach employing mechanical work (MW) determination and relative portion of its elemental analysis was applied to investigate the biomechanical causes of golf-related lumbar spine injuries. Kinematic and kinetic parameters at the lumbar and lower limb joints were measured during downswing in 18 golfers. The MW at the lumbar joint (LJ) was smaller than at the right hip but larger than the MWs at other joints. The contribution of joint angular velocity (JAV) to MW was much greater than that of net muscle moment (NMM) at the LJ, whereas the contribution of NMM to MW was greater rather than or similar to that of JAV at other joints. Thus, the contribution of JAV to MW is likely more critical in terms of the probability of golf-related injury than that of NMM. The MW-based golf-related injury index (MWGII), proposed as the ratio of the contribution of JAV to MW to that of NMM, at the LJ (1.55) was significantly greater than those at other joints ( golf-related injuries around the lumbar spine. Therefore, both MW and MWGII should be considered when investigating the biomechanical causes of lumbar spine injuries.

thirties to fifties, the age category most affected was in the forties range. Incident rate calculations (incidents per 100 training runs) revealed that the 2002, 2003, and 2004 time periods registered the highest reported incident rate levels (3.4, 6.1, and 4.1 respectively) when compared to the following years (all = 1.0). In addition to general hand-arm discomfort being the highest reported result from training, specific types of hand injuries or symptoms included erythema, fingernail delamination, abrasions, muscle soreness/fatigue, paresthesia, bruising, blanching, and edema. Specific body locations most affected by hand injuries included the metacarpophalangeal joints, fingernails, finger crotches, fingers in general, interphalangeal joints, and fingertips. Causes of injuries reported in the LSAH data were primarily attributed to the forces that the gloved hands were exposed to due to hand intensive tasks and/or poor glove sizing. DISCUSSION: Although the age data indicate that most injuries are reported by male crewmembers in their forties, that is also the dominant gender and age range of most EVA crew therefore it is not an unexpected finding. Age and gender analysis will continue as more details on the uninjured population is accrued. While there is a reasonable mechanism to link training quantity to injury, the results were inconsistent and point to the need for a consistent method of suit-related injury screening and documentation. For instance, the high-incident rate levels for the years 2002 to 2004 could be attributed to a comprehensive medical review of crewmembers post-NBL EVA training that occurred from July 19, 2002 to January 16, 2004. Furthermore, there could have been increased awareness from an investigation at the NBL. These investigations may have temporarily increased the fidelity of reported injuries and discomforts during these dates as compared to surrounding years, when injury signs and symptom were no longer actively being investigated but

[b]Abstract Objective.[/b] The aim of the study is to present four cases of lawn mowers injuries as a cause of serious visual acuity impairment. [b]Materials and Method[/b]. A retrospective study of four patients admitted in 2013-2015 to the Department of Vitreoretinal Surgery in Lublin with severe open or closed globe injury, one with an intraocular foreign body (IOFB). The presence of eye protective equipment was assessed, as well as visual acuity, eye tissue condition before and after treatment, and applied therapy. In all cases an improvement was achieved in local conditions. The intraocular foreign body was removed, wounds sutured and damaged tissues placed in position. All eyeballs were saved. In three cases, visual acuity was improved to a usable level. Three patients underwent pars plana vitrectomy, one with IOFB removal from the vitreous cavity. [b]Conclusions[/b]. Lawn mower induced eye injuries are a significant cause of serious visual acuity impairment or blindness. The presented study shows that lawn mower eye injuries are still a therapeutic, social and economic problem, yet are very preventable with proper eye protection and patients' education. Current prevention strategies are inadequate, and therefore should be updated.

The intestinal lymph pathway plays an important role in the pathogenesis of organ injury following superior mesenteric artery occlusion (SMAO) shock. We hypothesized that mesenteric lymph reperfusion (MLR) is a major cause of spleen injury after SMAO shock. To test this hypothesis, SMAO shock was induced in Wistar rats by clamping the superior mesenteric artery (SMA) for 1 h, followed by reperfusion for 2 h. Similarly, MLR was performed by clamping the mesenteric lymph duct (MLD) for 1 h, followed by reperfusion for 2 h. In the MLR+SMAO group rats, both the SMA and MLD were clamped and then released for reperfusion for 2 h. SMAO shock alone elicited: 1) splenic structure injury, 2) increased levels of malondialdehyde, nitric oxide (NO), intercellular adhesion molecule-1, endotoxin, lipopolysaccharide receptor (CD14), lipopolysaccharide-binding protein, and tumor necrosis factor-α, 3) enhanced activities of NO synthase and myeloperoxidase, and 4) decreased activities of superoxide dismutase and ATPase. MLR following SMAO shock further aggravated these deleterious effects. We conclude that MLR exacerbates spleen injury caused by SMAO shock, which itself is associated with oxidative stress, excessive release of NO, recruitment of polymorphonuclear neutrophils, endotoxin translocation, and enhanced inflammatory responses.

To examine trends in reporting injury as a cause of death among people with epilepsy in the U.S. during the past three decades. We analyzed the U.S. multiple causes of death data from death certificates in 1981-2010 to compare rate and odds ratios (OR) of reporting injury as cause of death among cases with vs. without mention of epilepsy across years. The trends in reporting epilepsy with and without injury were similar in most age groups but were inconsistent in most external causes of injury. The OR of reporting injury was 1.02 (95% confidence intervals (CI) 0.97-1.07) in 1981-1985 and decreased to 0.52 (95% CI 0.48-0.55) in 2006-2010. The decline in OR was prominent among people aged 15-24 followed by people aged 25-44. For the five external causes of injury, the OR of suffocation and drowning were 6.32 (95% CI 5.91-6.75) and 5.64 (95% CI 5.16-6.16) in 1981-1985 and decreased to 3.03 (95% CI 2.74-3.35) and 2.56 (95% CI 2.18-3.00) in 2006-2010. The OR for poisoning and traffic crashes were 0.70 (95% CI 0.57-0.85) and 0.08 (95% CI 0.07-0.09) in 1981-1985 and 0.21 (95% CI 0.18-0.25) and 0.06 (95% CI 0.05-0.08) in 2006-2010. The risk of fatal injury among people with epilepsy decreased drastically during the past three decades in most age groups and for most external causes of injury except falls. People with epilepsy had lower risks of dying from injury due to poisoning or traffic crashes, had higher risks of dying from suffocation and drowning. Copyright © 2014 British Epilepsy Association.

To assess the effect of virtual reality distraction on pain among patients with a hand injury undergoing a dressing change. Virtual reality distraction can effectively alleviate pain among patients undergoing a dressing change. Clinical research has not addressed pain control during a dressing change. A randomised controlled trial was performed. In the first dressing change sequence, 98 patients were randomly divided into an experimental group and a control group, with 49 cases in each group. Pain levels were compared between the two groups before and after the dressing change using a visual analog scale. The sense of involvement in virtual environments was measured using the Pearson correlation coefficient analysis, which determined the relationship between the sense of involvement and pain level. The difference in visual analog scale scores between the two groups before the dressing change was not statistically significant (t = 0·196, p > 0·05), but the scores became statistically significant after the dressing change (t = -30·792, p virtual environment and pain level during the dressing was statistically significant (R(2) = 0·5538, p Virtual reality distraction can effectively alleviate pain among patients with a hand injury undergoing a dressing change. Better results can be obtained by increasing the sense of involvement in a virtual environment. Virtual reality distraction can effectively relieve pain without side effects and is not reliant on a doctor's prescription. This tool is convenient for nurses to use, especially when analgesics are unavailable. © 2014 John Wiley & Sons Ltd.

Full Text Available Introduction. Optic nerve avulsion is a serious injury of the eye. The objective of the paper was to present the peculiarity of the eye injury caused by a penetrating orbital wound with foreign body being retained in the orbit. Case report. A 15-year-old boy who sustained injury by chain link is presented. While he was turning the chain round in his hand, the last link broke off, piercing the lower lid, penetrated the left orbital cavity and remained behind the eyeball at the top of orbit. While passing towards the top of the orbit, the foreign body caused a blunt injury of the eyeball and avulsion of the ocular nerve. The accurate localization of the foreign body was verified by X-ray and CT imaging. The foreign body was removed through the entry wound. The eye injury resulted in amaurosis. Conclusion. This injury was one of those that could have been prevented.

Does the cause of the mild traumatic brain injury affect the expectation of persistent postconcussion symptoms and psychological trauma?

Science.gov (United States)

Sullivan, Karen A; Wade, Christina

2017-05-01

A controlled experiment of the effect of injury cause on expectations of outcome from mild traumatic brain injury (TBI) was conducted. Ninety-three participants were randomly assigned to one of four conditions. The participants read a vignette that described a mild TBI (with fixed injury parameters) from a different cause (sport, domestic assault, fall, or motor vehicle accident). The effect of the manipulation on expectations of persistent postconcussion symptoms and psychological trauma was assessed with standard measures and a novel "threat-to-life" measure. The Kruskal-Wallis H test for group differences revealed a significant but selective effect of group on symptom and trauma outcomes (ŋ 2 s ≥ .10; large effects). Post hoc pairwise tests showed that, in most cases, there was an expectation of a worse outcome following mild TBI from a domestic assault than from the other causes (small-to-medium effects). Expectations were selectively altered by an experimental manipulation of injury cause. Given that expectations of outcome are known to affect mild TBI prognosis, the findings suggest the need for greater attention to injury cause.

The first step in infection control is hand hygiene.

Science.gov (United States)

Canham, Leslie

2011-01-01

A dental health care worker (DHCW) has an obligation to prevent the spread of health care associated infections. Adhering to proper hand hygiene procedures, selecting appropriate hand hygiene products and the use of gloves are all important elements of infection control. The CDC Guidelines for Hand Hygiene state that improved hand hygiene practices can reduce transmission of pathogenic microorganisms to patients and personnel in health care settings. DHCWs must also protect themselves by recognizing pitfalls such as irritants or allergies that may pose obstacles to proper hand hygiene. Occupational irritants and allergies can be caused by frequent hand washing, exposure to hand hygiene products, exposure to chemicals and shear forces associated with wearing or removing gloves. Since the primary defense against infection and transmission of pathogens is healthy, unbroken skin, DHCWs must take steps to ensure that their skin remains healthy and intact. These steps include evaluating different types of hand hygiene products, lotions and gloves for the best compatibility. If the DHCW sees a breakdown of his or her skin barrier, steps should be taken to determine the cause and remedy. Remedies can include the use of alcohol-based hand sanitizers containing emollients and moisturizers and regular use of a medical grade hand lotion. The bottom line: healthy skin protects you at work and at home. Selection and use of appropriate hand hygiene products, including moisturizers, are an essential part ofa dental office infection control program. My coworker lost the use of her thumb for several months due to complications of a staph infection. She was unable to work and found even simple tasks such as closing a button hard to do. Think of how difficult your work would be if something happened to your hands. Injury, irritation or allergies could alter your ability to work or even perform routine tasks. Our hands provide us with the ability to work in clinical dentistry. It makes

Slaughterer's guns ("humane killers") are powder-activated cattle skull impacting tools. Today mechanical stunning is typical for country like regions, because in the municipal slaughter-houses electrical stunning of pigs and ruminants is preferred. In rare cases these weapons are used for suicide. They then cause penetrating brain lesions and if the victim survives the brain-damage, an encephalitis caused by the impacted material results. The neurosurgical treatment is to revise the gunshot canal and to remove impacted fragments of bone and contaminated skin (imprimat) under antibiotic cover. A psychiatric treatment of the mostly underlying depression and a rehabilitative treatment should complete therapy. So treatment of slaughterer's gun injury should have a multidisciplinary approach.

Regaining upper extremity function is the primary concern of persons with tetraplegia caused by spinal cord injury (SCI). Robotic rehabilitation has been inadequately tested and underutilized in rehabilitation of the upper extremity in the SCI population. Given the acceptance of robotic training in stroke rehabilitation and SCI gait training, coupled with recent evidence that the spinal cord, like the brain, demonstrates plasticity that can be catalyzed by repetitive movement training such as that available with robotic devices, it is probable that robotic upper-extremity training of persons with SCI could be clinically beneficial. The primary goal of this pilot study was to test the feasibility of using a novel robotic device for the upper extremity (RiceWrist) and to evaluate robotic rehabilitation using the RiceWrist in a tetraplegic person with incomplete SCI. A 24-year-old male with incomplete SCI participated in 10 sessions of robot-assisted therapy involving intensive upper limb training. The subject successfully completed all training sessions and showed improvements in movement smoothness, as well as in the hand function. Results from this study provide valuable information for further developments of robotic devices for upper limb rehabilitation in persons with SCI. © 2011 IEEE

Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries. A 24-question online survey was distributed to rock climbers about upper extremity injuries sustained during rock climbing. Statistical analysis was used to study association between participants' demographics and injuries. A total of 397 participants responded to the survey. Mean age was 32.5 years with males comprising 85%. No significant differences in demographics or climbing behaviors were found between males and females. Ninety percent of participants reported sustaining an upper extremity injury. Fingers were the most common injury followed by shoulder/arm and elbow/forearm. Our study found females to be more likely to report a rock climbing-related injury, and more likely to undergo surgery for it. Female rock climbers were significantly more likely to report a shoulder/upper arm injury and were also more likely to report undergoing surgery compared with males, where these differences were not due to age or climbing behaviors. Further investigation is warranted into the association between shoulder injuries and female athletes to determine how the gender differences relate to extent of injury as well as health service utilization behaviors.

Acute kidney injury (AKI) with hyperparathyroidism caused by nitrite was rare, and renal function and parathyroid hormone (PTH) decreased to normal range after therapy. Acute kidney injury was diagnosed in a 40-year-old male with hyperparathyroidism and cyanosis of his hands and both forearms. The patient ate some recently pickled vegetables, and he experienced nausea, vomiting and diarrhoea without oliguria or anuria; Additionally, his hands and both forearms had a typical blue ash appearance. After admission, the laboratory findings indicated theincreasing serum creatinine (Scr) and parathyroid hormone (PTH). He was diagnosed as acute kidney injury with hyperparathyroidism caused by nitrite. The patient stopped eating the pickled vegetables and was given rehydration, added calories and other supportive therapy without any glucocorticoids. According to his clinical manifestations, laboratory findings and imaging results, the patient was diagnosed with acute kidney injury with secondary hyperparathyroidism. He was given symptomatic supportive care therapy. After one week, the serum creatinine, parathyroid hormone (PTH), hypercalcemia, hyperphosphatemia, proteinuria, and urine red blood cell values decreased to normal range. Nitrite-induced acute kidney injury with secondary hyperparathyroidism was relatively rare. After therapy, the function of the kidney and parathyroid returned to normal. This case suggests that detailed collection of medical history, physical examination and correct symptomatic treatment is very important.

Full Text Available Introduction. Injuries caused by aircraft bombs cause severe damages to the human body. They are characterized by massive destruction of injured tissues and organs, primary contamination by polymorph bacterial flora and modified reactivity of the body. Upon being wounded by aircraft bombs projectiles a victim simultaneously sustains severe damages of many organs and organ systems due to the fact that a large number of projectiles at the same time injure the chest, stomach, head and extremities. Case report. We presented a patient, 41 years of age, injured by aircraft bomb with hemo-pneumothorax and destruction of the bone and soft tissue structures of the foot, as well as the treatment result of such heavy injuries. After receiving thoracocentesis and short reanimation, the patient underwent surgical procedure. The team performed thoracotomy, primary treatment of the wound and atypical resection of the left lung. Thoracic drains were placed. The wounds on the lower leg and feet were treated primarily. Due to massive destruction of bone tissue of the right foot by cluster bomb splinters, and impossibility of reconstruction of the foot, guillotine amputation of the right lower leg was performed. Twelve days after the wounding caused by cluster bomb splinters, soft tissue of the left lower leg was covered by Tirsch free transplantant and the defect in the area of the left foot was covered by dorsalis pedis flap. The transplant and flap were accepted and the donor sites were epithelized. Twenty-six days following the wounding reamputation was performed and amputation stump of the right lower leg was closed. The patient was given a lower leg prosthesis with which he could move. Conclusion. Upon being wounded by aircraft bomb splinters, the injured person sustains severe wounds of multiple organs and organ systems due to simultaneous injuries caused by a large number of projectiles. It is necessary to take care of the vital organs first because they

A high incidence of anterior cruciate ligament (ACL) injuries related to sports activities has been reported; however, the injury situation of ACL injury in badminton has not been elucidated. This study investigated the mechanism of ACL injury in badminton using a questionnaire. Information on injury mechanism was gathered from interviews with six male and 15 female badminton players who received a non-contact ACL injury playing badminton and underwent ACL reconstruction. The most common injury mechanism (10 of 21 injuries) was single-leg landing after overhead stroke. Nine of 10 players had injured the knee opposite to the racket-hand side. The second most frequent injury mechanism (eight of 21 injuries) was plant-and-cut while side-stepping or backward stepping. All eight players injured the knee of the racket-hand side. Eleven injuries occurred in the rear court, and six of the 11 injuries occurred during single-leg landing after an overhead stroke. The knee opposite to the racket-hand side tended to sustain the ACL injuries during single-leg landing after a backhand overhead stroke, whereas the knee of the racket-hand side tended to be injured by plant-and-cut during side or backward stepping. These injury patterns appear to be due to specific movements during badminton.

To characterize the types and external causes of pediatric injury-related visits (IRVs) to emergency departments (EDs), in particular, sports-related injuries. To compare the characteristics of children with IRVs with those with non-IRVs, specifically, differences in IRV rates by race and ethnicity and by health insurance. This was a stratified random-sample survey of EDs in the National Hospital Ambulatory Medical Care Survey (NHAMCS), including all IRVs for patients less than 19 years of age in 1998 (n = 2,656). National estimates of pediatric IRVs were obtained using the assigned patient visit weights in the NHAMCS databases and SUDAAN analyses. Measures of association between predictor variables (patient and health insurance characteristics) and whether a child had an IRV were calculated using multivariate logistic regression analyses to determine adjusted odds ratios with 95% confidence intervals. Pediatric IRVs accounted for more than 11 million ED visits annually. The most common diagnoses for IRVs were open wounds, contusions, sprains and strains, and fractures and dislocations. The leading external causes of IRVs were sports-related injuries, accidental falls, being struck by objects, and motor vehicle collisions. Children with IRVs differed from those who presented for non-IRVs in many characteristics: they were more likely to be male, to be older, to be of white race, and to have private insurance, and less likely to be of Asian or Hispanic ethnicity. Sports and recreation are the leading external causes of pediatric IRVs to EDs in the United States. There are different patterns of IRVs according to gender, age, race, ethnicity, and insurance. Identification of specific patterns of injury is necessary for the design of effective prevention strategies.

Injuries to the hands are common among astronauts who train for extravehicular activity (EVA). When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. Glove injuries, both anecdotal and recorded, have been reported during EVA training and flight persistently through NASA's history regardless of mission or glove model. Theories as to causation such as glove-hand fit are common but often lacking in supporting evidence. Previous statistical analysis has evaluated onycholysis in the context of crew anthropometry only. The purpose of this study was to analyze all injuries (as documented in the medical records) and available risk factor variables with the goal to determine engineering and operational controls that may reduce hand injuries due to the EVA glove in the future. A literature review and data mining study were conducted between 2012 and 2014. This study included 179 US NASA crew who trained or completed an EVA between 1981 and 2010 (crossing both Shuttle and ISS eras) and wore either the 4000 Series or Phase VI glove during Extravehicular Mobility Unit (EMU) spacesuit EVA training and flight. All injuries recorded in medical records were analyzed in their association to candidate risk factor variables. Those risk factor variables included demographic characteristics, hand anthropometry, glove fit characteristics, and training/EVA characteristics. Utilizing literature, medical records and anecdotal causation comments recorded in crewmember injury data, investigators were able to identify several risk factors associated with increased risk of glove related injuries. Prime among them were smaller hand anthropometry, duration of individual suited exposures, and improper glove-hand fit as calculated by the difference in the anthropometry middle finger length compared to the baseline EVA glove middle finger length.

Fireworks are the leading cause of injuries such as burns and amputations during the Persian Wednesday Eve Festival (Chaharshanbeh Soori). This study was designed to explore the age of the high-risk population, the type of fireworks most frequently causing injury, the pattern of injury, and the frequency of permanent disabilities. This cohort study was performed by Tehran Emergency Medical Services at different medical centers all around Tehran, Iran, in individuals referred due to firework-related injuries during 1 month surrounding the festival in the year 2007. The following information was extracted from the patients' medical records: demographic data, the type of fireworks causing injury, the pattern and severity of the injury, the pre-hospital and hospital care provided for the patient, and the patient's condition at the time of discharge. In addition, information on the severity of the remaining disability was recorded 8 months after the injury. There were 197 patients enrolled in the study with a mean age of 20.94 ± 11.31 years; the majority of them were male. Fuse-detonated noisemakers and homemade grenades were the most frequent causes of injury. Hand injury was reported in 39.8% of the cases. Amputation and long-term disability were found in 6 and 12 cases, respectively. None of the patients died during the study period. The fireworks used during a Chaharshanbe Soori ceremony were responsible for a considerable number of injuries to different parts of the body, and some of them led to permanent disabilities.

Full Text Available Abstract Background Aim of the study was to determine the effect of the regular use of a hand cream after washing hands on skin hydration and skin roughness. Methods Twenty-five subjects washed hands and forearms with a neutral soap four times per day, for 2 minutes each time, for a total of two weeks. One part of them used a hand cream after each hand wash, the others did not (cross over design after a wash out period of two weeks. Skin roughness and skin hydration were determined on the forearms on days 2, 7, 9 and 14. For skin roughness, twelve silicon imprint per subject and time point were taken from the stratum corneum and assessed with a 3D skin analyzer for depth of the skin relief. For skin hydration, five measurements per subject and time point were taken with a corneometer. Results Washing hands lead to a gradual increase of skin roughness from 100 (baseline to a maximum of 108.5 after 9 days. Use of a hand cream after each hand wash entailed a decrease of skin roughness which the lowest means after 2 (94.5 and 14 days (94.8. Skin hydration was gradually decreased after washing hands from 79 (baseline to 65.5 after 14 days. The hand wash, followed by use of a hand cream, still decreased skin hydration after 2 days (76.1. Over the next 12 days, however, skin hydration did not change significantly (75.6 after 14 days. Conclusion Repetitive and frequent hand washing increases skin dryness and roughness. Use of a hand cream immediately after each hand wash can confine both skin dryness and skin roughness. Regular use of skin care preparations should therefore help to prevent both dry and rough skin among healthcare workers in clinical practice.

There has been no comprehensive injury report of elite-level amateur boxers in competition and training. We reviewed injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2009. Longitudinal, prospective injury surveillance over 5 years of the GB boxing squad from 2005 to 2009. 66 boxers passed through the squad. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training, and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 h. More injuries affected the hand than any other body location. This was the case overall, in training and competition individually, and for both new and recurrent injuries. More injuries occurred during training than during competition, and most injuries were new rather than recurrent. Total injury rate during competition was 828 per 1000 h and hand injury rate in competition was 302 injuries per 1000 h. Hand injury rate in competition was significantly higher than at the other locations. The incidence of concussion is comparatively low. Injury prevention should aim to protect the hands and wrists of elite amateur boxers. Published by the BMJ Publishing Group Limited.

To survey participants at various experience levels of different martial arts (MA) about upper extremity injuries sustained during training and fighting. A 21-s question survey was designed and utilised. The survey was divided into four groups (Demographics, Injury Description, Injury Mechanism, and Miscellaneous information) to gain knowledge about upper extremity injuries sustained during martial arts participation. Chi-square testing was utilised to assess for significant associations. Males comprised 81% of respondents. Involvement in multiple forms of MA was the most prevalent (38%). The hand/wrist was the most common area injured (53%), followed by the shoulder/upper arm (27%) and the forearm/elbow (19%). Joint sprains/muscle strains were the most frequent injuries reported overall (47%), followed by abrasions/bruises (26%). Dislocations of the upper extremity were reported by 47% of participants while fractures occurred in 39%. Surgeries were required for 30% of participants. Females were less likely to require surgery and more likely to have shoulder and elbow injuries. Males were more likely to have hand injuries. Participants of Karate and Tae Kwon Do were more likely to have injuries to their hands, while participants of multiple forms were more likely to sustain injuries to their shoulders/upper arms and more likely to develop chronic upper extremity symptoms. With advanced level of training the likelihood of developing chronic upper extremity symptoms increases, and multiple surgeries were required. Hand protection was associated with a lower risk of hand injuries. Martial arts can be associated with substantial upper extremity injuries that may require surgery and extended time away from participation. Injuries may result in chronic upper extremity symptoms. Hand protection is important for reducing injuries to the hand and wrist.

Injury and poisoning are a growing public health concern in China due to rapid economic growth, which has resulted in many cases with an injury-prone environment, such as overcrowded traffic, booming construction, and work-related stress. This study investigates the distribution and trends of deaths from injury and poisoning in Tianjin, China, by age, sex and urban/rural status, from 1999 to 2006. The study used data from the all-cause mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Each death certificate recorded 53 variables. Cause of death was coded using the International Classification of Diseases (ICD). Standardized mortality rates and proportions of deaths were analyzed. Traffic accidents, suicide, poisoning, drowning and fall were the leading causes of fatal injuries in Tianjin from 1999 to 2006. Injury mortality rates were high in males, in rural areas, and in the older age groups. Despite low injury mortality rates, injury accounted for close to 50% of all deaths amongst the 5-29 year age group. Traffic accident mortality rates increased, although not significantly so, during the period from 1999 to 2006. Injury prevention and control is a high public health priority in Tianjin. Our detailed table on the number of deaths by causes of fatal injuries and by age group provides important information to set prevention strategies in the nurseries, schools, workplace and seniors homes. 2009 Elsevier Ltd.

The aim of this study was to evaluate defects caused by torsional fatigue in used hand and rotary nickel-titanium (Ni-Ti) instruments by stereomicroscopic examination. One hundred five greater taper Ni-Ti instruments were used including Protaper universal hand (Dentsply Maillefer, Ballaigues, Switzerland), Protaper universal rotary (Dentsply Maillefer, Ballaigues, Switzerland), and Revo-S rotary (MicroMega, Besançon, France) files. Files were used on lower anterior teeth. After every use, the files were observed with both naked eyes and stereomicroscope at 20× magnification (Olympus, Shinjuku, Tokyo, Japan) to evaluate defects caused by torsional fatigue. Scoring was assigned to each file according to the degree of damage. The results were statistically analyzed using the Mann-Whitney U test and the Kruskal-Wallis test. A greater number of defects were seen under the stereomicroscope than on examining with naked eyes. However, the difference in methods of evaluation was not statistically significant. Revo-S files showed minimum defects, while Protaper universal hand showed maximum defects. The intergroup comparison of defects showed that the bend in Protaper universal hand instruments was statistically significant. Visible defects in Ni-Ti files due to torsional fatigue were seen by naked eyes as well as by stereomicroscope. This study emphasizes that all the files should be observed before and after every instrument cycle to minimize the risk of separation.

Robot-assisted training provides an effective approach to neurological injury rehabilitation. To meet the challenge of hand rehabilitation after neurological injuries, this study presents an advanced myoelectric pattern recognition scheme for real-time intention-driven control of a hand exoskeleton. The developed scheme detects and recognizes user's intention of six different hand motions using four channels of surface electromyography (EMG) signals acquired from the forearm and hand muscles, and then drives the exoskeleton to assist the user accomplish the intended motion. The system was tested with eight neurologically intact subjects and two individuals with spinal cord injury (SCI). The overall control accuracy was [Formula: see text] for the neurologically intact subjects and [Formula: see text] for the SCI subjects. The total lag of the system was approximately 250[Formula: see text]ms including data acquisition, transmission and processing. One SCI subject also participated in training sessions in his second and third visits. Both the control accuracy and efficiency tended to improve. These results show great potential for applying the advanced myoelectric pattern recognition control of the wearable robotic hand system toward improving hand function after neurological injuries.

Hand fractures are the second most common fracture of the upper extremity, and management of patients with these injuries is common for most hand surgery practices. In this article, we outline the principles of management of these injuries with a special focus on those that are common or complex. We also highlight recent innovations in the context of these injuries. From this cross-section of contemporary evidence on phalangeal and metacarpal fracture treatment, we have noted a trend toward minimally invasive surgery with immediate postoperative mobilization, the use of wide-awake anesthesia, as well as sustained investigation and innovation in the biomechanics and treatment of proximal interphalangeal joint fracture dislocations.

Background: Vinyl chloride (VC) causes toxicant-associated steatohepatitis at high exposure levels. Recent work by this group suggests that underlying liver disease may predispose the liver to VC hepatotoxicity at lower exposure levels. The most common form of underlying liver disease in the developed world is non-alcoholic fatty liver disease (NAFLD). It is well-known that the type of dietary fat can play an important role in the pathogenesis of NAFLD. However, whether the combination of dietary fat and VC/metabolites promotes liver injury has not been studied. Methods: Mice were administered chloroethanol (CE - a VC metabolite) or vehicle once, 10 weeks after being fed diets rich in saturated fatty acids (HSFA), rich in poly-unsaturated fatty acids (HPUFA), or the respective low-fat control diets (LSFA; LPUFA). Results: In control mice, chloroethanol caused no detectable liver injury, as determined by plasma transaminases and histologic indices of damage. In HSFA-fed mice, chloroethanol increased HSFA-induced liver damage, steatosis, infiltrating inflammatory cells, hepatic expression of proinflammatory cytokines, and markers of endoplasmic reticulum (ER) stress. Moreover, markers of inflammasome activation were increased, while markers of inflammasome inhibition were downregulated. In mice fed HPUFA all of these effects were significantly attenuated. Conclusions: Chloroethanol promotes inflammatory liver injury caused by dietary fatty acids. This effect is far more exacerbated with saturated fat, versus poly-unsaturated fat; and strongly correlates with a robust activation of the NLRP3 inflammasome in the saturated fed animals only. Taken together these data support the hypothesis that environmental toxicant exposure can exacerbate the severity of NAFLD/NASH. - Highlights: • CE promotes inflammatory liver injury caused by dietary fatty acids. • This effect is stronger with saturated than with unsaturated fatty acids. • Damage caused by saturated fat and CE

Moreover, markers of inflammasome activation were increased, while markers of inflammasome inhibition were downregulated. In mice fed HPUFA all of these effects were significantly attenuated. Conclusions: Chloroethanol promotes inflammatory liver injury caused by dietary fatty acids. This effect is far more exacerbated with saturated fat, versus poly-unsaturated fat; and strongly correlates with a robust activation of the NLRP3 inflammasome in the saturated fed animals only. Taken together these data support the hypothesis that environmental toxicant exposure can exacerbate the severity of NAFLD/NASH. - Highlights: • CE promotes inflammatory liver injury caused by dietary fatty acids. • This effect is stronger with saturated than with unsaturated fatty acids. • Damage caused by saturated fat and CE

To investigate tree-related injuries in Solomon Islands by the types of trees involved, who is affected and the types of injuries caused. Descriptive case series of all cases of injuries related to trees presenting to the National Referral Hospital in Honiara from 1994 to 2011. Data were collected by the attending clinician using a Trauma Epidemiology form, which provides information on age, sex, cause of injury and type of fracture. Number of injuries by tree type, sex and age. Of the 7651 injuries in the database, 1107 (14%) were caused by falls from trees. Falls from coconut trees led to the highest number of injuries, followed by falls from mango, guava, apple and nut trees. Overall, 85% of injuries occurred in individuals aged trees, 77% of patients were aged tree types. Overall, 71% of injuries occurred among males. Of all injuries, 92% were fractures, 3% were dislocations and 5% were non-fracture, non-dislocation injuries. The arm (including wrist, elbow and hand) was the most common location of injury across all tree types. Distal radius fractures in the forearm were particularly common, as were ulna fractures. While mangos and guavas are undeniably delicious, the quest for their flesh can be hazardous. Children will always climb trees, but the search for food among children in lower-income settings may lead to higher rates of injury.

Electronic cigarettes (e-cigarettes) contain lithium batteries that have been known to explode and/or cause fires that have resulted in burn injury. The purpose of this article is to present a case study, review injuries caused by e-cigarettes, and present a novel classification system from the newly emerging patterns of burns. A case study was presented and online media reports for e-cigarette burns were queried with search terms "e-cigarette burns" and "electronic cigarette burns." The reports and injury patterns were tabulated. Analysis was then performed to create a novel classification system based on the distinct injury patterns seen in the study. Two patients were seen at our regional burn center after e-cigarette burns. One had an injury to his thigh and penis that required operative intervention after ignition of this device in his pocket. The second had a facial burn and corneal abrasions when the device exploded while he was inhaling vapor. The Internet search and case studies resulted in 26 cases for evaluation. The burn patterns were divided in direct injury from the device igniting and indirect injury when the device caused a house or car fire. A numerical classification was created: direct injury: type 1 (hand injury) 7 cases, type 2 (face injury) 8 cases, type 3 (waist/groin injury) 11 cases, and type 5a (inhalation injury from using device) 2 cases; indirect injury: type 4 (house fire injury) 7 cases and type 5b (inhalation injury from fire started by the device) 4 cases. Multiple e-cigarette injuries are occurring in the United States and distinct patterns of burns are emerging. The classification system developed in this article will aid in further study and future regulation of these dangerous devices.

In order to evaluate the special injury pattern of aggressive inline skating, a field study was conducted in a local, non-commercial skate park equipped with all the typical features like ramps, halfpipes, gully areas. 66 unselected aggressive inline skaters were randomly enrolled and interviewed concerning their skating habits and their skating injury history. Average age was 15 (10 to 41) years, skating was performed since 2.1 (0.1 to 6) years, as aggressive skating since 1.3 (0.1 to 4) years. Medical treatment in a doctor's practice or in a hospital had been necessary in 66 cases, averaging 1.4 times per skater and year, averaging one injury per 586 hours of aggressive skating. The injury pattern reflected the regions typically injured in fitness skating, too, with a higher percentage of injuries concerning knee, tibia and ankle region. The use of protective devices varied from 41 % (wrist guards) to 94 % (knee pads), with an average of 69 %. Only 32 % of skaters wore all protective devices. As the personal thrill is an important motivation for aggressive skating, safer skating campaigns are quite unlikely to decrease the risk of injury in aggressive skaters.

Full Text Available The mechanical harvesting causes injuries on seeds and may affect their quality. Different threshing mechanisms and their adjustments may also affect the intensity of impacts that machines cause on seeds. So, this study aimed at diagnosing and evaluating the effect of two combines: the first one with a threshing system of axial flow and the other one with a threshing system of tangential flow, under adjustments of concave opening (10 mm, 30 mm and 10 mm for a combine with axial flow and 3.0 mm, 15 mm and 3.0 mm for a combine with tangential flow and three cylinder rotations on the quality of soybean seeds harvested at two moisture contents. Soybean seeds of cultivar 'ND 4910' were harvested at 16.6% moisture (mid - morning and 13.7% moisture in the afternoon. The seeds quality was evaluated by germination tests, germination speed index (GSI, germination rate, moisture content, percentage of purity and vigor by tetrazolium test. Despite the combine, the results showed that the mechanical injury has most reduced seeds quality, at 16.6% moisture content, concave opening of 30 mm (axial and 10 mm (tangential and cylinder rotation of 1100 rpm (axial and 1000 (tangential, both with the highest rotations used. The combine with tangential flow had the highest degree of seeds purity. When seeds moisture content at harvest was close to 13.7%, there was the highest seed injury, while, at 16.6%, there was the highest number of crushed soybeans, regardless the combine adjustment.

The upper hand on compartment syndrome.

Metacarpal fractures are common injuries, accounting for approximately 30% to 40% of all hand fractures and with a lifetime incidence of 2.5%. Traditionally regarded as an innocuous injury, metacarpal fractures tend to be associated with successful outcomes after closed reduction and immobilization. Hand compartment syndrome (HCS) is a rare clinical entity with potential devastating consequences in terms of loss of function and quality-of-life outcomes. We discuss the case of a 44-year-old woman presenting with multiple closed metacarpal fractures as a result of low-energy trauma, complicated by acute HCS. We review the presentation, clinical assessment, and optimal surgical management of acute HCS with reference to international literature.

The purpose of this study was to observe the occurrence and character of firework injuries on the two days around New Year in Denmark over the last decade. Since 1995/1996 all Accident and Emergency Departments in Denmark have registered all contacts where fireworks were the cause of injury on 31st December and 1st January. Data comprised hospital, sex, age, type of firework, diagnosis and final treatment. Follow-up and reminder by phone secured a 100% response rate. The total number of injured patients was 4,447. The number of firework injuries on the 31st of December and 1st of January was reduced by half over the 12-year period. Furthermore, the number of firework injuries caused by illegal fireworks in 2006/2007 was only 10% of the number in 1996/1997. Only 8% of injuries on last New Year's Eve were caused by illegal firewoks compared to almost 50% at the beginning of the period. A similar halving is seen in serious injuries. Roughly one quarter sustained injuries to the eyes, one quarter to the head/neck and 38% to hands. Firework injuries are now half of the level in 1996/1997. Injuries caused by illegal fireworks and serious injuries have shown a downward tendency throughout the period. The actual number of severe injuries from illegal fireworks is now only 10% of the level in the mid-1990s. This reduction can be attributed to preventive campaigns, greater knowledge of the risk of fireworks in general as well as legislation. Continued focus on preventive campaigns, control of fireworks for the general public and control of firework distribution to professionals is recommended.

Full Text Available The aim of this study to analyse the occurrence of injuries in undergraduates of the Physical Education Course at the State University of Maringá. Types of injuries were diagnosed, the opinion of students and professors with regard to their probable causes was taken and the factors that could render injuries less damaging were identified. Research was carried out in the second semester of 1991 when 231 students were regularly enlisted. Data were collected by means of questionnaires for professors and for students. Forty injury cases were verified, 13 with males and 27 with females. The most common type of injury was bruises (55% followed by strain (18%. The inferior members were the most affected region. Judo was the subject in which the greatest number of injuries occurred. Students stated that salient probable causes were: agressivity of colleages in practical exercises (33% and defective sports facilities (25%. In the professors opinion, however, the two chief causes were: students’ distraction (20% and physical inability (20%. The establishment of an Internal Commission for the Prevention of Accidents has been suggested made up of professors, under graduate students and personnel of the Physical Education Department at the State University of Maringá. Its aims are to carry out a following up of this situation, to promote the prevention of injuries and to suggest possible improvements in the premises.

Objective: Rhabdomyolysis (RM) is a common disorder resulting from a large variety of causes. Acute injury is one of the main reasons. The purpose is to describe the MRI manifestations of rhabdomyolysis caused by 5.12 Wenchuan earthquake in Sichuan province and to discuss their importance in diagnosis and treatment of rhabdomyolysison in clinic practice. Methods: Three patients with rhabdomyolysis caused by earthquake were studied via 1.5 T MRI. In all the patients, T 1 and T 2 weighted sequences with and without fat suppression, and short time inversion recovery (STIR) of both lower extremities were obtained in axial, coronal and sagittal planes. All patients were given contrast material during imaging, and MRA (magnetic resonance angiography) of both lower extremity vessels were performed. The MRI characteristics of damaged extremities in 3 cases were studied. Results: MRI showed swelling of the affected muscles and subcutaneous fat tissue on both T 1 and T 2 weighted images. The margins of involved muscles were blurred. On T 1 weighted images, swollen muscles showed equal or slightly decreased intensity with small patterns of increased intensity in some local areas. On T 2 weighted and STIR sequences, the affected muscles showed inhomogeneous increased signal intensity with clearer margin. Slight fluid collection in spatium intermusculare was observed. Contrast-enhanced scanning showed nonhomologous intensification of damaged muscles, the enhancement inside the muscles was decreased when compared with normal muscles. The locations of all these abnormal intensity were correlated with the injury history and clinic physical examinations. MRA showed no lower extremity vessels were affected. Conclusion: MRI has very high sensitivity in detecting the injury of muscles. It's very useful in evaluating the extent and severity of muscles affected in rhabdomyolysis caused by trauma. Also it's very valuable to evaluate the condition of blood vessels in involved extremity

Instability of the knee after the medial collateral ligament (MCL) injury is usually assessed with the manual valgus stress test, even though, in recent years, it has become possible to apply magnetic resonance imaging (MRI) to the assessment of the damage of the ligament. The valgus instability of 24 patients (12 isolated injuries and 12 multiple ligament injuries) who suffered MCL injury between 1993 and 1998 was evaluated with the Hughston and Eilers classification, which involves radiographic assessment under manual valgus stress to the injured knees. We developed a novel system for classifying the degree of injury to the MCL by calculating the percentage of injured area based on MRI and investigated the relationship between this novel MRI classification and the magnitude of valgus instability by the Hughston and Eilers classification. There was a significant correlation between the 2 classifications (p=0.0006). On the other hand, the results using other MRI based classification systems, such as the Mink and Deutsch classification and the Petermann classification, were not correlated with the findings by the Hughston and Eilers classification in these cases (p>0.05). Since MRI is capable of assessing the injured ligament in clinical practice, this novel classification system would be useful for evaluating the stability of the knee and choosing an appropriate treatment following MCL injury.

Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

Splenic irradiation in the course of therapy for lymphoma can result in functional deficit, sometimes as severe as that caused by splenectomy, placing the patient at risk for fatal infection. We examined 33 spleens obtained at necropsy from patients irradiated for lymphomas (mainly Hodgkin's disease) and compared them with 18 nonirradiated spleens from similar patients. One to 8 years after a mean radiation dose of 3899 rads, fractionated over 5-6 weeks, most irradiated spleens were small (average weight 75 g) and had thick, wrinkled capsules, often with focal hemorrhage. There was collapse of the parenchyma, with close apposition of trabeculae and mild to severe diffuse fibrosis of the red pulp. Lymphocyte depletion was obvious in more than 50% of the specimens. The most consistent alteration was myointimal proliferation of arteries. Significant intimal thickening was seen only in the irradiated specimens. Similar myointimal changes were found in the veins of three cases. While none of these changes is specific, their combination appears to be characteristic of delayed radiation injury to the spleen

Trauma is the most common etiologic factor leading to disability in the hand and wrist. Judicious radiographic evaluation is required for accurate assessment in practically all but the most minor of such injuries. Frequently serial radiographic evaluation is essential for directing the course of treatment and for following the healing process. A meaningful radiographic evaluation requires a comprehensive knowledge of the normal radiographic anatomy, an overview of the spectrum of pathology, and an awareness of the usual mechanisms of injury, appropriate treatment options, and relevant array of complications

This study sought to describe variations in the risk of motor vehicle collision (MVC) injury and death by occupant body mass index (BMI) class and vehicle type. We hypothesized that the relationship between BMI and the risk of MVC injury or mortality would be modified by vehicle type. This is a retrospective cohort study of occupants involved in MVCs using data from the Crash Injury Research and Engineering Network and the National Automotive Sampling System Crashworthiness Data System. Occupants were grouped based on vehicle body style (passenger car, sport utility vehicle, or light truck) and vehicle size (compact or normal, corresponding to below- or above-average curb weight). The relationship between occupant BMI class (underweight, normal weight, overweight, or obese) and risk of injury or mortality was examined for each vehicle type. Odds ratios (ORs) adjusted for various occupant and collision characteristics were estimated. Of an estimated 44 million occupants of MVCs sampled from 2000 to 2009, 37.1% sustained an injury. We limited our analysis to injuries achieving an Abbreviated Injury Scale (AIS) score of 2 or more severe, totaling 17 million injuries. Occupants differed substantially in terms of demographic and collision characteristics. After adjustment for confounding factors, we found that obesity was a risk factor for mortality caused by MVC (OR, 1.6; 95% confidence interval [CI], 1.2-2.0). When stratified by vehicle type, we found that obesity was a risk factor for mortality in larger vehicles, including any-sized light trucks (OR, 2.1; 95% CI, 1.3-3.5), normal-sized passenger cars (OR, 1.6; 95% CI, 1.1-2.3), and normal-sized sports utility vehicles or vans (OR, 2.0; 95% CI, 1.0-3.8). Being overweight was a risk factor in any-sized light trucks (OR, 1.5; 95% CI, 1.1-2.1). We identified a significant interaction between occupant BMI class and vehicle type in terms of MVC-related mortality risk. Both factors should be taken into account when

Esophageal Foreign Body Causing Direct Aortic Injury

Directory of Open Access Journals (Sweden)

ECS Lam

2003-01-01

Full Text Available Foreign bodies in the esophagus are uncommon causes of esophageal perforation. Many nonperforating cases are successfully managed by flexible gastroscopy. However, complicated foreign bodies such as those that result in esophageal perforation and vascular injury are best managed surgically. Gastroscopy remains the primary method of diagnosis. A case of a 59-year-old woman who developed retrosternal and intrascapular pain, odynophagia and hematemesis after eating fish is reported. Flexible gastroscopy showed arterial bleeding from the midthoracic esophagus. Computed tomography scan localized a 3 cm fish bone perforating the esophagus with surrounding hematoma. An aortogram did not reveal an actively bleeding aortoesophageal fistula. The fish bone was surgically removed and the patient recovered with no postoperative complications. This case illustrates the importance of early consideration for surgical intervention when confronted with a brisk arterial bleed from the esophagus with suggestive history of foreign body ingestion.

Full Text Available Objective 　Through the establishment of adjacent cabin blast injury model of Beagle dog, to investigate the pathophysiological changes in the experimental animals in this scenario, then speculate on the mechanisms of injury. Methods 　Several adjacent cabins were built in the same size with the real warship. Seven Beagle dogs were subjected to injuries from the explosion, from whom one was selected randomly to implant intracranial pressure transducers before blast, the others were tested on the pathophysiological changes after blast. The dogs were mounted on the platform of a cabinet in the adjacent cabin, subjected to injury from 650g bare TNT explosive blast. The transducers recorded the value of space and intracranial shock wave pressure. Following blast treatment, the serum levels of IL -6, IL -8, neuron specific enolase (NSE, brain and chest CT and pathological changes of the brain tissue were observed. Results 　Serum levels of IL-6, IL-8 and NSE were elevated to varying degrees after blast. All of them increased significantly at different time points after blast (P<0.05. Brain and chest CT examinations did not show any significant positive results. Pathological results showed that there was a little necrosis in the brain, some neurons had karyopycnosis, karyolysis or disappearance of the nucleoli, and the cell boundaries were blurred. The blast wave was blocked greatly by the scalp and skull (about 90%, but could still penetrate them and cause brain injuries. Conclusions 　Explosion in the adjacent cabin causes mainly mild traumatic brain injuries. Blast wave can be blocked by the scalp and skull greatly. DOI: 10.11855/j.issn.0577-7402.2017.03.11

Objective Aging is a major risk factor for increased ischemic tissue injury. Whether collateral rarefaction and impaired remodeling contribute to this is unknown. We quantified the number and diameter of native collaterals, and their remodeling in 3-, 16-, 24-, and 31-months-old mice. Methods and Results Aging caused an “age-dose-dependent” greater drop in perfusion immediately after femoral artery ligation, followed by a diminished recovery of flow and increase in tissue injury. These effects were associated with a decline in collateral number, diameter and remodeling. Angiogenesis was also impaired. Mechanistically, these changes were not accompanied by reduced recruitment of T-cells or macrophages to remodeling collaterals. However, eNOS signaling was dysfunctional, as indicated by increased protein nitrosylation and less phosphorylated eNOS and VASP in collateral wall cells. The cerebral circulation exhibited a similar age-dose-dependent loss of collateral number and diameter and increased tortuosity, resulting in an increase in collateral resistance and infarct volume (e.g., 6- and 3-fold, respectively, in 24-months-old mice) after artery occlusion. This was not associated with rarefaction of similarly-sized arterioles. Collateral remodeling was also reduced. Conclusions Our findings demonstrate that aging causes rarefaction and insufficiency of the collateral circulation in multiple tissues, resulting in more severe ischemic tissue injury. PMID:21617137

the Series 4000 glove had a lower injury risk than the Phase VI, which provides a platform for further evaluation. General interventions that reduce hand overexertion and repetitive use exposure through tool development, procedural changes and shorter exposures may be one mitigation path, but due to the way the training event times were reported, we cannot provide a guideline for a specific event duration change. When the finger length was different from the glove length, the risk of injury increased indicating that the use of larger finger take-ups could be contributing to injury and therefore may not be recommended. Prior to this investigation, there was one previous investigation indicating hand anthropometry may be related to onycholysis. We found different hand anthropometry variables indicated by this investigation as compared to the prior, specifically differences in middle finger length compared to glove finger length, which point more towards a sizing issue than a specific anthropometry issue. Additionally, although this investigation has identified sizing as an issue, the force and environmental-related variables of the EVA glove that could also cause injury were not accounted for.

Objectives: Adenosine has been shown in animal and human studies to decrease the post-ischemic myocardial injury by lowering the levels of tumor necrosis factor-a. The objectives of the study was to examine the protective effects of adenosine on the organ injury (liver, kidney, pancreas) associated with hemorrhagic shock in rats. Methodology: The study was conducted at Cardiovascular Physiology laboratory, King Saud University, Riyadh in 2007-2008. Anesthetized male Sprague- Dawley rats were assigned to hemorrhage and resuscitation treated with 20mM adenosine , untreated, or similar time matched control groups (n=6 per group). Rats were hemorrhaged for one hour using a reservoir model. Arterial blood pressure was monitored for one hour, and maintained at a mean arterial blood pressure of 40 mmHg. Adenosine 20mM was injected intra-arterially, before resuscitation in the adenosine treated group. Resuscitation was performed by re infusion of the sheded blood for 30 minutes. Arterial blood samples were analyzed for biochemical indicators of multiple organ injury: 1) liver function: aspartate aminotransferase (AST), alanine aminotransferase (ALT), 2) renal function: urea and creatinine, 3) pancreatic function: amylase. Results: In the control group there was no significant rise in the serum levels of (i) urea and creatinine, (ii) aspartate aminotransferase (AST) and alanine aminotransferase (ALT), (iii) amylase. While in the adenosine treated group, resuscitation from one hour of hemorrhagic shock resulted in significant rises in the serum levels of (i) urea and creatinine, (ii) aspartate aminotransferase (AST) and alanine aminotransferase (ALT), (iii) amylase. Treatment of rats with 20mM adenosine before resuscitation following one hour of hemorrhagic shock decreased the multiple organ injury and dysfunction caused by hemorrhagic shock. Conclusion: Adenosine attenuated the renal, liver and pancreatic injury caused by hemorrhagic shock and resuscitation in rats. Thus

Full Text Available Objective　To reproduce and evaluate a rat model of inhalation lung injury caused by black gunpowder smog. Methods　The smog composition was analyzed and a rat model of inhalation lung injury was reproduced. Forty two healthy male Wistar rats were randomly divided into normal control (NC group and 1h, 2h, 6h, 24h, 48h and 96h after inhalation group (n=6. The arterial blood gas, wet to dry weight ratio (W/D of lung, leukocyte count, and protein concentration in broncho-alveolar lavage fluid (BALF were determined. Macroscopic and microscopic changes in lung tissue were observed. Results　The composition of black gunpowder smog was composed mainly of CO2 and CO, and their concentrations remained stable within 12 minutes. Smog inhalation caused a significant hypoxemia, the concentration of blood COHb reached a peak value 1h, and the W/D of lung reached peak value 2h after inhalation (P<0.05. The amount of leukocytes and content of protein in BALF increased significantly within 24h after inhalation (P<0.05. Histopathological observation showed diffuse hemorrhage, edema and inflammatory cell infiltration in lung tissue as manifestations of acute lung injury, and the injury did not recover at 96h after inhalation. Conclusion　The rat model of inhalation lung injury can be reproduced using black gunpowder smog, and it has the advantages of its readiness for reproduction, reliability and stability, and it could be used for the experiment of inhalation injury in a battlefield environment.

Commercially available bioethanol-fueled fireplaces have become increasingly popular additions for interior home decoration in Europe and more recently in the United States. These fireplaces are advertised as smokeless, ecologically friendly, and do not require professional installation, formal gas lines, or venting. Although manufacturers and businesses promote their safety, recent presentations of injuries have alerted the authors to the relevant danger bioethanol fireplaces can pose for the incautious user. Are bioethanol fireplaces going to become the future threat in domestic burn accidents beside common barbeque burns? A Medline literature search on barbeque and domestic fireplace accidents was performed to compare and stratify the injury patterns reported and to identify a risk profile for contemporary bioethanol-fueled fireplaces. To exemplify, two representative clinical cases of severe burn accidents caused by bioethanol-fueled fireplaces, both treated in the burn unit of the authors, are being presented. Design fireplaces are being recognized as an increasing source of fuel and fire-related danger in the home. This risk may be underestimated by the uninformed customer, resulting in severe burn injuries. Because bioethanol-fueled fireplaces have become more commonplace, they may overtake barbecue-related injury as the most common domestic burn injury.

2001-01-01

In this paper we present the case of a radiologist performing interventional procedures. The radiologist works for number of interventional procedures, but we reported only percutaneous nephrostomy and percutaneous biliary drainage which represent about 30% of his occupational exposure. The radiologist is occupationally exposed for eighteen years and from 1995 has radiation injuries. From 1999, art. hypertension, cataract complicata incip.ou., onychodystrophia and hyperceratosis mani bill. The most important are hands skin injuries. In ordinary dosimetric control low doses less than 10 mGy per year were recorded, so personal dosimetry results and biological results are not in accordance. For that reason we performed additional measurements during many procedures and in this paper we present results for two chosen procedures. Radiation exposure of the radiologist's hands during 200 percutaneous nephrostomy and 63 percutaneous biliary drainage per year are reported. Exposures were measured with thermoluminescent dosemeters (TLD) type CaF 2 :Mn. Hand doses of equivalent of 221 μSv in average per drainage and 31 μSv in average per nephrostomy were recorded.

The incidence of femoral neck and trochanteric fractures reportedly differ by age and regionality. We investigated differences in monthly variations of the occurrence of femoral neck and trochanteric fractures as well as place and cause of injury in the Kyoto prefecture over a 6-year period. Fracture type (neck or trochanteric fracture), age, sex, place of injury, and cause of injury were surveyed among patients aged ≥ 65 years with hip fractures that occurred between 2008 and 2013 who were treated in 1 of 13 participating hospitals (5 in an urban area and 8 in a rural area). The proportion of sick beds in the participating hospitals was 24.7% (4,151/16,781). Monthly variations in the number of patients were investigated in urban and rural areas in addition to the entire Kyoto prefecture. Place of injury was classified as indoors or outdoors, and cause of injury was categorized as simple fall, accident, or uncertain. There were 2,826 patients with neck fractures (mean age, 82.1 years) and 3,305 patients with trochanteric fractures (mean age, 85.0 years). There were similarities in the monthly variation of the number of fractures in addition to the place and cause of injury between neck and trochanteric fractures. Indoors (approximately 74%) and simple falls (approximately 78%) were the primary place and cause of injury, respectively. The place of injury was not significantly different by fracture type with each age group. Significantly more patients with neck fracture had "uncertain" as the cause of injury than trochanteric fracture in all age groups. Based on the results of the present study, the injury pattern might not have a great effect on the susceptibility difference between neck and trochanteric fractures.

The SHAM Insurance Company in Lyon, France, estimated that inadequate hand wound exploration in the emergency room (ER) accounted for 10% of all ER-related personal injury claims in 2013. The objective of this study was to conduct a critical analysis of 80 claims that were related to hand wound management in the ER and led to compensation by SHAM. Eighty claims filed between 2007 and 2010 were anonymised then included into the study. To be eligible, claims had to be filed with SHAM, related to the ER management of a hand wound in an adult, and closed at the time of the study. Claims related to surgery were excluded. For each claim, we recorded 104 items (e.g., epidemiology, treatments offered, and impact on social and occupational activities) and analysed. Of the 70 patients, 60% were manual workers. The advice of a surgeon was sought in 16% of cases. The most common wound sites were the thumb (33%) and index finger (17%). Among the missed lesions, most involved tendons (74%) or nerves (29%). Many patients had more than one reason for filing a claim. The main reasons were inadequate wound exploration (97%), stiffness (49%), and dysaesthesia (41%). One third of patients were unable to return to their previous job. Mean sick-leave duration was 148 days and mean time from discharge to best outcome was 4.19%. Most claims (79%) were settled directly with the insurance company, 16% after involvement of a public mediator, and 12% in court. The mean compensatory damages award was 4595Euros. Inadequate surgical exploration of hand wounds is common in the ER, carries a risk of lasting and sometimes severe residual impairment, and generates considerable societal costs. IV.

2014-05-01

We report a case of an orbital fracture and an eyeball rupture caused by a golf-club injury. A 75-year-old man was struck in his right eye by a golf club while watching behind his son swinging a hybrid-type golf club at his home. A 70-mm muscle-depth laceration was present in the infraorbital area with active bleeding. Computed tomographic imaging of the face revealed a rupture of the right eyeball; fractures in the superior, medial, lateral, and inferior wall of the right orbit; a fracture in the right zygomaticofrontal junction; and a small amount of pneumocephalus in the parafalx region. Under general anesthesia, evisceration of the right eyeball was performed. Not only golfers but also people just watching or passing by can be injured by an errantly struck golf ball or swung golf club. Elderly people as well as children should be instructed in technique and safety and also be supervised when playing golf. Also, the public should be educated about the risk of eye injuries and the benefits of wearing a protective eyewear.

Occupational injuries are a major problem in agriculture worldwide. In the Northeast region of India, most of the farm operations are carried out manually with hand operated tools and equipment. These tools also cause some nonfatal accidents. In the absence of reliable data on accidents in this region, injury prevention policy cannot be madeOBJECTIVE:The aim of this study was to survey injury causing agricultural accidents occurring during 2010 to 2013 in Arunachal Pradesh of the northeast region to know their magnitude, causes and severity. In this study, four districts of Arunachal Pradesh namely Papum Pare, Lower Subansiri, West Siang and East Siang were chosen using purposive sampling. From each district, 15 villages were selected. In these villages, a total of 50614 agricultural workers participated and 174 and 48 injuries were found for male and female workers respectively. A case-control study was carried out in Arunachal Pradesh. The questionnaire-based approach was used for data collection. The questionnaire contains detailed information on the demographic and injury characteristics. The Demographic information included gender, age, educational background, etc. and injury characteristics included the nature of the injury, the body part injured, and type of tools and equipment that caused the injury. The results showed that farm tools and equipment-related accidents were maximum i.e. 144 (60%) caused due to dao followed by 19 from spade (8%), 18 from sickle (7%) and 8 from axe (3%). The foot and legs were the most frequently injured body parts. From this study, it was also revealed that male agricultural workers are more affected as compared to their female counterparts. Agricultural accident incident rate (AIR) was found to be 589 per 1,00,000 workers per year. The AIR for males is 462 per 100,000 workers per year which is 3.6 times higher than female workers. The root causes of accidents are the use of traditional tools and equipment in various

Preventable thermal injuries in professional kitchen workers have been identified, and we have introduced a protective garment. Because of the nature of their occupation, kitchen workers are prone to thermal injuries. It has been our experience that the majority of these injuries are scald injuries on the ankles and dorsum of the feet. We propose that a protective garment, such as a waterproof shoe and garter, could reduce the incidence of these injuries.

A bi-modal visual processing model is supported by research to affect dysfunction following a traumatic brain injury (TBI). TBI causes dysfunction of visual processing affecting binocularity, spatial orientation, posture and balance. Research demonstrates that prescription of prisms influence the plasticity between spatial visual processing and motor-sensory systems improving visual processing and reducing symptoms following a TBI. The rationale demonstrates that visual processing underlies the functional aspects of binocularity, balance and posture. The bi-modal visual process maintains plasticity for efficiency. Compromise causes Post Trauma Vision Syndrome (PTVS) and Visual Midline Shift Syndrome (VMSS). Rehabilitation through use of lenses, prisms and sectoral occlusion has inter-professional implications in rehabilitation affecting the plasticity of the bi-modal visual process, thereby improving binocularity, spatial orientation, posture and balance Main outcomes: This review provides an opportunity to create a new perspective of the consequences of TBI on visual processing and the symptoms that are often caused by trauma. It also serves to provide a perspective of visual processing dysfunction that has potential for developing new approaches of rehabilitation. Understanding vision as a bi-modal process facilitates a new perspective of visual processing and the potentials for rehabilitation following a concussion, brain injury or other neurological events.

2017-08-01

Many stroke and spinal cord injury patients suffer from paralysis which range from severe to nominal. Some of them, after therapy, could regain most of the motor control, particularly in hands if the severity level is not so high. In this paper we propose a hand orthosis for such patients whose stroke and spinal cord injury severity is nominal and the motor control in hands can be regained by therapy as part of their rehabilitation process. The patients can wear this orthosis and the therapy can be done with simple Human Computer Interface. The physicians, the physiotherapists and the patients themselves can carry out the therapy with the help of this device. The tests conducted in the lab and the results obtained are very promising that this can be an effective mechanism for stroke and spinal cord injury patients in their rehabilitation process. The hand orthosis is designed and fabricated locally so that it can be made available to such patients at an affordable cost.

Injurious mechanical ventilation in the normal lung causes a progressive pathologic change in dynamic alveolar mechanics

OpenAIRE

Pavone, Lucio A; Albert, Scott; Carney, David; Gatto, Louis A; Halter, Jeffrey M; Nieman, Gary F

2007-01-01

Introduction Acute respiratory distress syndrome causes a heterogeneous lung injury, and without protective mechanical ventilation a secondary ventilator-induced lung injury can occur. To ventilate noncompliant lung regions, high inflation pressures are required to 'pop open' the injured alveoli. The temporal impact, however, of these elevated pressures on normal alveolar mechanics (that is, the dynamic change in alveolar size and shape during ventilation) is unknown. In the present study we ...

Penetrating head injuries with impacted foreign bodies are rare, associated with a high incidence of morbidity and potentially life-threatening. In this study, we aimed at investigating the outcome of these cases as well as analyzing the factors affecting the prognosis. A retrospective study in which the records of 16 patients who had penetrating head injuries caused by low-velocity impacted foreign bodies were revised. All patients were males with a mean age of 28.9 years (range, 18 to 50 years). The follow-up period ranged from 4 to 13 months with a mean of 8.1 months. Causes of injury were construction accidents in 6 (37.5 %) patients, assault in 6 (37.5 %) and road traffic accidents in 4 (25 %). The impacted objects included a bar of iron, a piece of wood, a nail, a sickle and a piece of glass. Diagnostic computerized tomography (CT) of the brain was carried out on admission in all patients. Thirteen (81.3 %) patients were submitted to surgery, and all had the appropriate management in the form of antibiotics and dehydrating measures as required. The primary outcome measure was the Glasgow Outcome Scale (GOS) at the end of follow-up. At the end of follow-up, ten (62.5 %) patients had a GOS score of 5, two (12.5 %) patients had a score of 4, and four (25 %) patients had a score of 1. Low-velocity penetrating head injuries are most common in young adult males. With the appropriate management, a majority of even the most severe cases can have a favorable outcome.

Biofeedback training is widely used for rehabilitative intervention in patients with central or peripheral nervous impairment to train correct movement patterns; however, no biofeedback apparatus is currently available to correct pinch force ratios for patients with sensory deficiencies. A cross-sectional and longitudinal design was used in an observational measurement study for establishing a prototype and to determine the effects of biofeedback intervention, respectively. This study aimed to develop a computerized evaluation and re-education biofeedback (CERB) prototype for application in clinical settings. A CERB prototype was developed integrating pinch apparatus hardware, a biofeedback user-controlled interface, and a data processing/analysis interface to detect momentary pinch performances in 79 people with normal hand sensation. Nine patients with hand sensory impairments were recruited to investigate the effects of training hand function with the CERB prototype. Hand dominance, pinch pattern, and age significantly affected the peak pinch force and force ratio for lifting a 480-g object with a steel surface. In the case of the 79 volunteers with normal hand sensation, hand dominance affected the time lag between peak pinch force and maximum load; however, it was unaffected by pinch pattern or age. Training with the CERB prototype produced significant improvements in force ratio and better performance in the pin insertion subtests, although the results for both 2-point discriminative and Semmes-Weinstein monofilament tests did not change significantly. The intervention findings are preliminary. This study developed a conjunct system suited for evaluating and restoring sensorimotor function for patients with impaired hand sensibility. The results from the participants with normal hand sensation could serve as a reference database for comparison with patients with nerve injuries.

Causes of ring-related leg injuries in birds - evidence and recommendations from four field studies.

Full Text Available One of the main techniques for recognizing individuals in avian field research is marking birds with plastic and metal leg rings. However, in some species individuals may react negatively to rings, causing leg injuries and, in extreme cases, the loss of a foot or limb. Here, we report problems that arise from ringing and illustrate solutions based on field data from Brown Thornbills (Acanthiza pusilla (2 populations, Siberian Jays (Perisoreus infaustus and Purple-crowned Fairy-wrens (Malurus coronatus. We encountered three problems caused by plastic rings: inflammations triggered by material accumulating under the ring (Purple-crowned Fairy-wrens, contact inflammations as a consequence of plastic rings touching the foot or tibio-tarsal joint (Brown Thornbills, and toes or the foot getting trapped in partly unwrapped flat-band colour rings (Siberian Jays. Metal rings caused two problems: the edges of aluminium rings bent inwards if mounted on top of each other (Brown Thornbills, and too small a ring size led to inflammation (Purple-crowned Fairy-wrens. We overcame these problems by changing the ringing technique (using different ring types or larger rings, or using different adhesive. Additionally, we developed and tested a novel, simple technique of gluing plastic rings onto metal rings in Brown Thornbills. A review of studies reporting ring injuries (N = 23 showed that small birds (35 g tend to get rings stuck over their feet. We give methodological advice on how these problems can be avoided, and suggest a ringing hazard index to compare the impact of ringing in terms of injury on different bird species. Finally, to facilitate improvements in ringing techniques, we encourage online deposition of information regarding ringing injuries of birds at a website hosted by the European Union for Bird Ringing (EURING.

Full Text Available Kidney stone disease is a common and important healt problem. For many years invasive surgical procedures are used for treatment. But, for 30 years, new options have emerged with the use of SWL. At first, clinicians supposed that SWL doesn%u2019t cause any damage to the kidney and other tissues nearby. But this idea has changed today, depending on the clinical experimental studies. By the time, clinical studies have revealed that the method had early and late side effects. Ischemia / reperfusion injury occurs during SWL, because renal blood flow changes during SWL. Thus, free oxygen radicals increases in kidney tissue, total antioxidant capacity decreases and acute kidney injury occurres, as shown in several studies. When the kidney proximal tubule cells are damaged, various molecules (especially glicoproteins are relesed from there. For example, KIM-1, IL-18, IL-6, NGAL, ICAM-1, %u03B22-microglobulin are some of the molecules used in the diagnosis and management of this injury. According to the results of studies, KIM-1 seems as the most useful marker in predicting the renal damage caused by SWL.

Approximately 100 firefighters suffer fatal injuries annually and tens of thousands receive nonfatal injuries. Many of these injuries require medical attention and restricted activity but may be preventable. This study was designed to elucidate etiology, circumstances, and patterns of firefighter burn injury so that further prevention strategies can be designed. In particular, modification of protective equipment, or turnout gear, is one potential strategy to prevent burn injury. An Institutional Review Board-approved retrospective review was conducted with records of firefighters treated for burn injury from 2005 to 2009. Data collected included age, gender, TBSA, burn depth, anatomic location, total hospital days per patient, etiology, and circumstances of injury. Circumstances of injury were stratified into the following categories: removal/dislodging of equipment, failure of equipment to protect, training errors, and when excessive external temperatures caused patient sweat to boil under the gear. Over the 4-year period, 20 firefighters were treated for burn injury. Mean age was 38.9 ± 8.9 years and 19 of 20 patients were male. Mean burn size was 1.1 ± 2.7% TBSA. Eighteen patients suffered second-degree burns, while two patients suffered first-degree burns. Mean length of hospitalization was 2.45 days. Scald burns were responsible for injury to 13 firefighters (65%). Flame burns caused injury to four patients (20%). Only three patients received contact burns (15%). The face was the site most commonly burned, representing 29% of injuries. The hand/wrist and ears were the next largest groups, with 23 and 16% of the injuries, respectively. Other areas burned included the neck (10%), arm (6.5%), leg (6.5%), knees (3%), shoulders (3%), and head (3%). Finally, the circumstance of injury was evaluated for each patient. Misuse and noncontiguous areas of protective equipment accounted for 14 of the 20 injuries (70%). These burns were caused when hot steam

Summary Background The incidence of femoral neck and trochanteric fractures reportedly differ by age and regionality. We investigated differences in monthly variations of the occurrence of femoral neck and trochanteric fractures as well as place and cause of injury in the Kyoto prefecture over a 6-year period. Methods Fracture type (neck or trochanteric fracture), age, sex, place of injury, and cause of injury were surveyed among patients aged ≥ 65 years with hip fractures that occurred between 2008 and 2013 who were treated in 1 of 13 participating hospitals (5 in an urban area and 8 in a rural area). The proportion of sick beds in the participating hospitals was 24.7% (4,151/16,781). Monthly variations in the number of patients were investigated in urban and rural areas in addition to the entire Kyoto prefecture. Place of injury was classified as indoors or outdoors, and cause of injury was categorized as simple fall, accident, or uncertain. Results There were 2,826 patients with neck fractures (mean age, 82.1 years) and 3,305 patients with trochanteric fractures (mean age, 85.0 years). There were similarities in the monthly variation of the number of fractures in addition to the place and cause of injury between neck and trochanteric fractures. Indoors (approximately 74%) and simple falls (approximately 78%) were the primary place and cause of injury, respectively. The place of injury was not significantly different by fracture type with each age group. Significantly more patients with neck fracture had “uncertain” as the cause of injury than trochanteric fracture in all age groups. Conclusions Based on the results of the present study, the injury pattern might not have a great effect on the susceptibility difference between neck and trochanteric fractures. PMID:27252738

Full Text Available Little is known about disability caused by unintentional injury (accidents worldwide. This study estimates the prevalence of disability caused by unintentional injury amongst people aged 15-60 years across different cities in the People’s Republic of China with the aim of providing a scientific basis for developing prevention and control programmes. The prevalence of disability caused by unintentional injury in this target group in sampled cities across the country was estimated from data from the Second Chinese National Sample Survey on Disability. Using the statistical evolution tree approach, cities automatically clustered into a tree structure according to the level of social security and industrial structure. The Kruskal- Wallis test was applied to compare the prevalence in various types of city. The results show that the prevalence of disability due to unintentional injury in the target population group varied significantly across the 16 types of city investigated, but that it was particularly common among the unemployed and poor. With regard to occupational structure, cities with activities oriented towards transport and construction had the highest average prevalence despite access to local, relatively sound social security systems and adequate medical resources. It was also found that people struck by unintentional injury were treated in various ways depending on the availability of social assistance, medical care and job training, which differed widely between cities depending on each city’s main occupational activity. High-risk cities areas were identified for that would benefit particularly by additional medical resource allocation as it would reduce their burden of unintentional injury.

2004-08-01

This study reports three cases of ulnar neuropathy after trampoline injuries in children. A chart review was performed on children who sustained an ulnar nerve injury from a trampoline accident. In all cases, surgical intervention was required. Injuries included upper-extremity fractures in two cases and an upper-extremity laceration in one case. All cases required surgical exploration with internal neurolysis and ulnar nerve transposition. Nerve grafts were used in two cases and an additional nerve transfer was used in one case. All patients had return of intrinsic hand function and sensation after surgery. Children should be followed for evolution of ulnar nerve neuropathy after upper-extremity injury with consideration for electrical studies and surgical exploration if there is no improvement after 3 months.

Šenolt, Ladislav

Hand osteoarthritis (OA) is a common chronic disorder causing pain and limitation of mobility of affected joints. The prevalence of hand OA increases with age and more often affects females. Clinical signs obviously do not correlate with radiographic findings - symptomatic hand OA affects approximately 26 % of adult subjects, but radiographic changes can be found in up to two thirds of females and half of males older than 55 years.Disease course differ among individual patients. Hand OA is a heterogeneous disease. Nodal hand OA is the most common subtype affecting interphalangeal joints, thumb base OA affects first carpometacarpal joint. Erosive OA represents a specific subtype of hand OA, which is associated with joint inflammation, more pain, functional limitation and erosive findings on radiographs.Treatment of OA is limited. Analgesics and nonsteroidal anti-inflammatory drugs are the only agents reducing symptoms. New insights into the pathogenesis of disease should contribute to the development of novel effective treatment of hand OA.

We tested the hypothesis that somatosensory system injury would more strongly affect movement than motor system injury in children with unilateral cerebral palsy (USCP). This hypothesis was based on how somatosensory and corticospinal circuits adapt to injury during development; whereas the motor system can maintain connections to the impaired hand from the uninjured hemisphere, this does not occur in the somatosensory system. As a corollary, cortical injury strongly impairs sensory function, so we hypothesized that cortical lesions would impair hand function more than subcortical lesions. Twenty-four children with unilateral cerebral palsy had physiological and anatomical measures of the motor and somatosensory systems and lesion classification. Motor physiology was performed with transcranial magnetic stimulation and somatosensory physiology with vibration-evoked electroencephalographic potentials. Tractography of the corticospinal tract and the medial lemniscus was performed with diffusion tensor imaging, and lesions were classified by magnetic resonance imaging. Anatomical and physiological results were correlated with measures of hand function using 2 independent statistical methods. Children with disruptions in the somatosensory connectivity and cortical lesions had the most severe upper extremity impairments, particularly somatosensory function. Motor system connectivity was significantly correlated with bimanual function, but not unimanual function or somatosensory function. Both sensory and motor connectivity impact hand function in children with USCP. Somatosensory connectivity could be an important target for recovery of hand function in children with USCP.

Alcohol abuse increases the risk for pancreatitis. The pattern of alcohol drinking may impact its effect. We tested a hypothesis that chronic ethanol consumption in combination with binge exposure imposes more severe damage to the pancreas. C57BL/6 mice were divided into four groups: control, chronic ethanol exposure, binge ethanol exposure and chronic plus binge ethanol exposure. For the control group, mice were fed with a liquid diet for two weeks. For the chronic ethanol exposure group, mice were fed with a liquid diet containing 5% ethanol for two weeks. In the binge ethanol exposure group, mice were treated with ethanol by gavage (5 g/kg, 25% ethanol w/v) daily for 3 days. For the chronic plus binge exposure group, mice were fed with a liquid diet containing 5% ethanol for two weeks and exposed to ethanol by gavage during the last 3 days. Chronic and binge exposure alone caused minimal pancreatic injury. However, chronic plus binge ethanol exposure induced significant apoptotic cell death. Chronic plus binge ethanol exposure altered the levels of alpha-amylase, glucose and insulin. Chronic plus binge ethanol exposure caused pancreatic inflammation which was shown by the macrophages infiltration and the increase of cytokines and chemokines. Chronic plus binge ethanol exposure increased the expression of ADH1 and CYP2E1. It also induced endoplasmic reticulum stress which was demonstrated by the unfolded protein response. In addition, chronic plus binge ethanol exposure increased protein oxidation and lipid peroxidation, indicating oxidative stress. Therefore, chronic plus binge ethanol exposure is more detrimental to the pancreas. - Highlights: • Chronic plus binge alcohol drinking causes more pancreatic injury. • Chronic plus binge alcohol drinking induces more pancreatic inflammation. • Chronic plus binge alcohol causes more endoplasmic reticulum stress and oxidative stress.

Terbinafine is an effective antimicrobial agent against dermatophytes, cryptococcus and other fungi. It is the preferred drug to treat onychomycosis. However, severe acute hepatitis from oral terbinafine administration has been recently reported. To describe a representative case, and review the literature regarding the best evidence on treatment and prognosis of severe acute hepatitis caused by oral terbinafine. The literature was searched for publications on severe hepatitis caused by terbinafine using MEDLINE, China Biology Medicine Disc, and the VIP Medical Information Resource System. Related references were searched manually. Seventeen English and three Chinese references of case reports were included after eliminating duplicate publications. No randomized control studies were found. Liver enzyme levels were found to have been increased significantly. Abdominal ultrasound demonstrated cholestasis. Severe acute liver injury is a known, but unusual complication of terbinafine exposure. The prognosis is often good with appropriate treatment. Liver function assessment before treatment and periodic monitoring 4-6 weeks after initiation of treatment is recommended.

Full Text Available Introduction: Gender-based violence (GBV against women has been identified as a global health and development issue. We reported a case of GBV causing sever, multiple injuries in a middle-aged female. Case report: A 47-year-old woman presented to emergency room with disturbed level of consciousness, shortness of breath and multiple patches of skin discoloration. On examination, the patient was semi-conscious, with multiple ecchymosis and bilateral decreased air entry. Computed tomography scan of the neck and chest showed six rib fractures on the left side, and eight rib fractures on the right side, sternal fracture, manubriosternal dislocation, bilateral hemothorax, fracture of body of eleventh thoracic vertebra, and fracture of cervical spine of fifth and seventh vertebrae. The patient was intubated and admitted to intensive care unit. She was discharged with good health condition after 23 days of hospital admission. Conclusion: GBV is still a cause of severe trauma that puts the patient’s life at risk.

Injuries in epilepsy: a review of its prevalence, risk factors, type of injuries and prevention

Full Text Available Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Seizures occurring in precarious situations and resulting in injuries are still an important concern for patients with epilepsy, their employers and their caregivers. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. These concerns seem valid because the hallmark of epilepsy, episodic impairment of consciousness and motor control, may occur during interictal EEG epileptiform discharges, even in the absence of a clinical seizure. In addition, psychomotor comorbidity and side effects of antiepileptic drugs may contribute to the risk of injuries in patients with epilepsy. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, epidemiological information about incidence of injuries has been conflicting and sparse. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based on non-selected populations of people with epilepsy have not shown an increased frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include: more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. Potentially the high rate of

Enterovirus 96 (EV-96) is a recently described member of the species Enterovirus C and is associated with paralysis and myelitis. In this study, using metagenomic sequencing, we identified a new enterovirus 96 strain (EV-96-SZ/GD/CHN/2014) as the sole pathogen causing hand, foot, and mouth disease (HFMD). A genomic comparison showed that EV-96-SZ/GD/CHN/2014 is most similar to the EV-96-05517 strain (85% identity), which has also been detected in Guangdong Province. This is the first time that metagenomic sequencing has been used to identify an EV-96 strain shown to be associated with HFMD.

Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2,565) showed that the oldest categories (19-22 and 23-30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to "dropping" and "pinching" in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines.

Full Text Available ABSTRACT INTRODUCTION: the fishing activity throughout the Upper Paraguay River Basin has huge financial and biological importance. This retrospective study investigated the occurrence of injuries caused by fish of the Pseudoplatystoma genus (spotted catfish or pintado and striped catfish or cachara in professional fishermen of the Pantanal of Mato Grosso do Sul State. METHODS: we collected information through a questionnaire, showing that fishing is carried out by workers with low level of education, mainly adults or seniors with low financial gains. RESULTS: in Miranda town, 126 of 315 fishermen were interviewed and 38 individuals reported injuries (30.16%. In Corumbá town, 355 of 627 fishermen were interviewed, and 111 (56,61% reported injuries. The lacerated lesions were the most common, associate with edema, erythema, radiating pain to the root of the limb, paresthesias and local necrosis. More rarely, they reported the occurrence of fever, cardiac arrhythmias and cold sweating. These manifestations may be associated with late secondary infections or envenomations caused by the toxins in the stingers of the fish. Many questionable and inappropriate treatments are used, sometimes aggravating the injuries. CONCLUSIONS: the freshwater professional fishermen need guidance on first aid measures and prevention of accidents caused by these venomous fish.

[The neuroprotective effect of erigeron breviscapus (vant) hand-mazz on retinal ganglion cells after optic nerve crush injury].

To investigate whether a Chinese herbal medicine, erigeron breviscapus (vant) hand-mazz (EBHM), can protect the retinal ganglion cells (RGC) damaged by calibrated optic nerve crush injury. Forty-two Sprague-Dawley rats were randomly divided into two groups. Calibrated optic nerve crush injury model was induced in the right eyes by a special designed optic nerve clip. The left eyes served as a control. All 42 rats were randomly divided into 2 groups. Group A consisted of the rats with calibrated optic nerve crush injury and group B consisted of rats with calibrated optic nerve crush injury treated with EBHM. In group B, EBHM solution was given once after the crush injury. According to the time interval between the optic nerve crush and the sacrifice, both groups A and B were further divided into three subgroups (day 4, day 14 and day 21). Therefore, there were 7 rats in each subgroup. Three days before sacrifice, 3% fast blue was injected into superior colliculi bilaterally. The eyes were enucleated after the rat was sacrificed, and flat mounts of the retina from both eyes were prepared on a slide and observed under a fluorescence microscope. Four photos with 400 x magnification were taken from each of the four quadrants of the retina 1 mm away from the optic disc. The labeled RGC were counted by a computerized image analyzer. The labeled RGC rate was used for statistical analysis (the labeled RGC rate = number of RGC in injured eye/control eye x 100%). In group A, the labeled RGC rate was (77.79 +/- 7.11)%, (63.76 +/- 3.79)% and (54.66 +/- 4.75)% on day 4, day 14 and day 21, respectively. In group B, the labeled RGC rate was (80.13 +/- 12.03)%, (78.17 +/- 9.19)% and (83.59 +/- 12.61)% on day 4, day 14 and day 21, respectively. In group B, which was treated with EBHM after injury, the labeled RGC rate was significantly higher than that of group A on day 14 and day 21. In the experimental optic nerve crush model in rats, EBHM therapy can increase the survival rate of

To evaluate whether low energy shock wave preconditioning could reduce renal ischemic reperfusion injury caused by renal artery occlusion. The right kidneys of 64 male Sprague Dawley rats were removed to establish an isolated kidney model. The rats were then divided into four treatment groups: Group 1 was the sham treatment group; Group 2, received only low-energy (12 kv, 1 Hz, 200 times) shock wave preconditioning; Group 3 received the same low-energy shock wave preconditioning as Group 2, and then the left renal artery was occluded for 45 minutes; and Group 4 had the left renal artery occluded for 45 minutes. At 24 hours and one-week time points after reperfusion, serum inducible nitric oxide synthase (iNOS), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), creatinine (Cr), and cystatin C (Cys C) levels were measured, malondialdehyde (MDA) in kidney tissue was detected, and changes in nephric morphology were evaluated by light and electron microscopy. Twenty-four hours after reperfusion, serum iNOS, NGAL, Cr, Cys C, and MDA levels in Group 3 were significantly lower than those in Group 4; light and electron microscopy showed that the renal tissue injury in Group 3 was significantly lighter than that in Group 4. One week after reperfusion, serum NGAL, KIM-1, and Cys C levels in Group 3 were significantly lower than those in Group 4. Low-energy shock wave preconditioning can reduce renal ischemic reperfusion injury caused by renal artery occlusion in an isolated kidney rat model.

Chemical irritants used in crowd control, such as tear gases and pepper sprays, are generally considered to be safe and to cause only transient pain and lacrimation. However, there are numerous reports that use and misuse of these chemicals may cause serious injuries. We aimed to review documented injuries from chemical irritants to better understand the morbidity and mortality associated with these weapons. We conducted a systematic review using PRISMA guidelines to identify injuries, permanent disabilities, and deaths from chemical irritants worldwide between January 1, 1990 and March 15, 2015. We reviewed injuries to different body systems, injury severity, and potential risk factors for injury severity. We also assessed region, context and quality of each included article. We identified 31 studies from 11 countries. These reported on 5131 people who suffered injuries, two of whom died and 58 of whom suffered permanent disabilities. Out of 9261 total injuries, 8.7% were severe and required professional medical management, while 17% were moderate and 74.3% were minor. Severe injuries occurred to all body systems, with the majority of injuries impacting the skin and eyes. Projectile munition trauma caused 231 projectile injuries, with 63 (27%) severe injuries, including major head injury and vision loss. Potentiating factors for more severe injury included environmental conditions, prolonged exposure time, and higher quantities of chemical agent in enclosed spaces. Although chemical weapons may have a limited role in crowd control, our findings demonstrate that they have significant potential for misuse, leading to unnecessary morbidity and mortality. A nuanced understanding of the health impacts of chemical weapons and mitigating factors is imperative to avoiding indiscriminate use of chemical weapons and associated health consequences.

The aim of this article was to explore retrospectively the Takei dynamometer as a valid and reliable outcome measure tool for hand and wrist pathology in the Great Britain amateur boxing squad between 2010 and 2014. Longitudinal retrospective injury surveillance of the Great Britain boxing squad was performed from 2010 to 2014. The location, region affected, description, and duration of each injury were recorded by the team doctor and team physiotherapists. For each significant injury, we recorded hand grip scores using the Takei handheld dynamometer and compared the scores with baseline measures. At the hand, fractures and dislocations were highly detected with an average difference of 40.2% ( P 20% should be highly considered for significant pathology. The Takei dynamometer is a valid and reliable outcome measure tool for hand and wrist pathologies in boxing. Our study highlights the importance of appropriate clinical tools to guide injury management in this sport.

Fall from height is one of the important causes of musculoskeletal injuries. Fall from walnut trees constitutes an important entity that leads to a significant mortality and morbidity amongst those engaged in fruit collection. The present study aimed to determine the prevalence of different musculoskeletal injuries in these victims and to highlight the importance of recognizing this incident as an occupational injury. A retrospective study of all patients admitted to the Orthopedic Department of the Sher-i-Kashmir Institute of Medical Sciences (SKIMS) Medical College from January 2003 to December 2007 was conducted. The medical records were studied for the different types of bony injuries, associated injuries and delay in the referral of patients. 94% of falls occurred from August to October. Of the 115 patients, 63 (54.7%) had associated non-orthopedic injuries. Head injury was the most common associated injury, presenting in 34 patients (29.5%). Thoracolumbar (16.5%), calcaneum (10.5%) and distal radius (8.7%) fractures constituted the common fractures encountered in the victims. Walnut tree injuries mostly involve young males who form the productive group of the population. Being a seasonal injury, it puts a considerable load on the health resources of the region over a small period of time.

During extra-vehicular activities (EVAs) or spacewalks astronauts over use their fingertips under pressure inside the confined spaces of gloves/space suits. The repetitive hand motion is a probable cause for discomfort and injuries to the fingertips. We describe a new wireless fiber-optic probe that can be integrated inside the astronaut glove for noninvasive blood perfusion measurements in distal fingertips. In this preliminary study, we present blood perfusion measurements while performing hand-grip exercises simulating the use of space tools.

Previously, we showed that the ventral premotor cortex (PMv) underwent neurophysiological remodeling after injury to the primary motor cortex (M1). In the present study, we examined cortical connections of PMv after such lesions. The neuroanatomical tract tracer biotinylated dextran amine was injected into the PMv hand area at least 5 months after ischemic injury to the M1 hand area. Comparison of labeling patterns between experimental and control animals demonstrated extensive proliferation of novel PMv terminal fields and the appearance of retrogradely labeled cell bodies within area 1/2 of the primary somatosensory cortex after M1 injury. Furthermore, evidence was found for alterations in the trajectory of PMv intracortical axons near the site of the lesion. The results suggest that M1 injury results in axonal sprouting near the ischemic injury and the establishment of novel connections within a distant target. These results support the hypothesis that, after a cortical injury, such as occurs after stroke, cortical areas distant from the injury undergo major neuroanatomical reorganization. Our results reveal an extraordinary anatomical rewiring capacity in the adult CNS after injury that may potentially play a role in recovery.

Mazur, L J; Yetman, R J; Risser, W L

1993-07-01

The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the use of weight machines, most apparently happen during the aggressive use of free weights. Prepubescent and older athletes who are well trained and supervised appear to have low injury rates in strength training programmes. Good coaching and proper weightlifting techniques and other injury prevention methods are likely to minimise the number of musculoskeletal problems caused by weight-training.

Serum and bronchoalveolar fluid IL-6 are increased in patients with acute respiratory distress syndrome (ARDS) and predict prolonged mechanical ventilation and poor outcomes, although the role of intra-alveolar IL-6 in indirect lung injury is unknown. We investigated the role of endogenous and exogenous intra-alveolar IL-6 in AKI-mediated lung injury (indirect lung injury), intraperitoneal (IP) endotoxin administration (indirect lung injury) and, for comparison, intratracheal (IT) endotoxin administration (direct lung injury) with the hypothesis that IL-6 would exert a pro-inflammatory effect in these causes of acute lung inflammation. Bronchoalveolar cytokines (IL-6, CXCL1, TNF-α, IL-1β, and IL-10), BAL fluid neutrophils, lung inflammation (lung cytokines, MPO activity [a biochemical marker of neutrophil infiltration]), and serum cytokines were determined in adult male C57Bl/6 mice with no intervention or 4 hours after ischemic AKI (22 minutes of renal pedicle clamping), IP endotoxin (10 µg), or IT endotoxin (80 µg) with and without intratracheal (IT) IL-6 (25 ng or 200 ng) treatment. Lung inflammation was similar after AKI, IP endotoxin, and IT endotoxin. BAL fluid IL-6 was markedly increased after IT endotoxin, and not increased after AKI or IP endotoxin. Unexpectedly, IT IL-6 exerted an anti-inflammatory effect in healthy mice characterized by reduced BAL fluid cytokines. IT IL-6 also exerted an anti-inflammatory effect in IT endotoxin characterized by reduced BAL fluid cytokines and lung inflammation; IT IL-6 had no effect on lung inflammation in AKI or IP endotoxin. IL-6 exerts an anti-inflammatory effect in direct lung injury from IT endotoxin, yet has no role in the pathogenesis or treatment of indirect lung injury from AKI or IP endotoxin. Since intra-alveolar inflammation is important in the pathogenesis of direct, but not indirect, causes of lung inflammation, IT anti-inflammatory treatments may have a role in direct, but not indirect, causes of ARDS.

IT IL-6 also exerted an anti-inflammatory effect in IT endotoxin characterized by reduced BAL fluid cytokines and lung inflammation; IT IL-6 had no effect on lung inflammation in AKI or IP endotoxin.IL-6 exerts an anti-inflammatory effect in direct lung injury from IT endotoxin, yet has no role in the pathogenesis or treatment of indirect lung injury from AKI or IP endotoxin. Since intra-alveolar inflammation is important in the pathogenesis of direct, but not indirect, causes of lung inflammation, IT anti-inflammatory treatments may have a role in direct, but not indirect, causes of

This report evaluates the June 2008 onychomadesis outbreak in Valencia, Spain. The study sample consisted of 221 onychomadesis cases and 77 nonaffected individuals who lived close to those affected. We collected data on dietary variables, hygiene products, and individual pathological histories. Feces and blood specimens were collected from 44 cases and 24 controls to evaluate exposure to infectious agents. Pathological background data revealed a high frequency (61%) of hand, foot, and mouth disease among the onychomadesis cases. Coxsackievirus A10 was the most commonly detected enterovirus in both case and control groups (49%). Other enteroviruses such as coxsackieviruses A5, A6, A16, B1, and B3; echoviruses 3, 4, and 9; and enterovirus 71 were present in low frequencies in the case and control groups (3-9%). The 2008 onychomadesis outbreak in the metropolitan area of Valencia was associated with an outbreak of hand, foot, and mouth disease primarily caused by coxsackievirus A10. © 2010 Wiley Periodicals, Inc.

Full Text Available ABSTRACTPostmortem injuries are a source of misinterpretations in forensic analysis and therefore are subject matter of taphonomic interest. Many types of injuries can cause different artifacts, which deserve attention of the forensic pathologists when evaluating corpses, either at the crime scene or during an autopsy. Insects can be important biotaphonomic agents and their activity may result in artifacts that resemble antemortem injuries. Here, we describe postmortem injuries caused by the Neotropical wasp Agelaia fulvofasciata (Degeer, 1773 on domestic pig carcasses weighting 15 kg. The specimens showed extensive injuries to the lower lip, similar to lacerations, and some minor lesions on the snout and anus. In addition, we observed the same wasp species preying on larvae of Sarcophagidae (Peckia sp.. Besides causing postmortem injuries, the ability of this species to detect carcasses in the early and fresh decomposition stages should be noted. Thus, future applications aiming criminal, any biotaphonomic events caused by carrion insects need to be disclosed.

Smog inhalation is associated with acute respiratory symptoms in exposed victims. However, despite the evidence from cell injury caused by smog, a stable and practical apparatus used to treat cells with smog is necessary. The aim of this study is to develop a cell research platform of smoke inhalation injury. In the smog-generation device, a wireless electromagnetic heater was used to ignite gunpowder and generate smog. The quality of black powder was checked by the black powder burn rate, and experimental smog was indirectly checked by the amount of cell damage. The temperature and humidity were set at 37 °C ± 1 °C and ≥95% in the smog-cells reaction chamber, respectively. Factors including gunpowder dosages, smog-exposure time, the cell density, modes of exposure, volumes of smog, test durations, volumes of the cell culture medium and combustion velocity were measured. Coefficient variation of different batches of gunpowder and smog were less than 4% and 9%, respectively. With larger gunpowder dosage and longer exposure time, cell injury appeared to increase. When cells were cultured in 4 × 10(4)/well density in culture medium (1 mL/well), exposed to more than 10 L smog with filter screens above plates, detected after 24 h culture in cell incubator and gunpowder burned out within 5 s, smog had the best effect on cell injury. In conclusion, the experimental device can produce test smog stably and safely. The apparatus treating cells with smog can induce cell injury effectively, and the injury is positively correlated with smog concentration and exposure time.

Full Text Available Background . Childhood injuries and accidents constitute an important health, social and economic problem. Serious injuries require surgical intervention and hospitalization. In other cases, patients leave hospital within several hours after diagnosis and non-operative treatment, and then they receive outpatient care. Despite a downward trend, injuries remain the main cause of death among children and adolescents. Therefore, understanding their epidemiology, which would allow us to create prevention programs based on scientific evidence (evidence based medicine, is so important. Objectives. The study’s objective was an attempt at analyzing childhood injuries treated in outpatient clinics. Material and methods. The study comprised 2182 children aged 0–18, including 692 females and 1490 males. Among them 1024 children treated surgically and 1158 outpatients. In the retrospective study the authors used a method of analysis of medical records of patients treated in 2012 at the Department of Child Surgery and Traumatology and Orthopaedics with the Operating Theatre in the Nicolaus Copernicus Province Hospital in Koszalin. The analysis was conducted on the basis of operative reports in the case of afflictions and injuries requiring surgery, and outpatient admissions reports in the case of outpatients. Results. Among the outpatients, the biggest group of injuries (34.83% or 403 included bruises, cuts, lacerations etc. Regarding frequency, injuries of hand area – 14.35% (166 and arm fractures – 13.4% (159 followed. Conclusions . 1. The age and gender of patients were factors determining injuries. 2. Seasons of the year have an influence on the structure of injuries among children. 3. It is necessary to increase social awareness on the prevention and negative effects of burns.

A Proposed Treatment for Visual Field Loss caused by Traumatic Brain Injury using Interactive Visuotactile Virtual Environment

Science.gov (United States)

Farkas, Attila J.; Hajnal, Alen; Shiratuddin, Mohd F.; Szatmary, Gabriella

In this paper, we propose a novel approach of using interactive virtual environment technology in Vision Restoration Therapy caused by Traumatic Brain Injury. We called the new system Interactive Visuotactile Virtual Environment and it holds a promise of expanding the scope of already existing rehabilitation techniques. Traditional vision rehabilitation methods are based on passive psychophysical training procedures, and can last up to six months before any modest improvements can be seen in patients. A highly immersive and interactive virtual environment will allow the patient to practice everyday activities such as object identification and object manipulation through the use 3D motion sensoring handheld devices such data glove or the Nintendo Wiimote. Employing both perceptual and action components in the training procedures holds the promise of more efficient sensorimotor rehabilitation. Increased stimulation of visual and sensorimotor areas of the brain should facilitate a comprehensive recovery of visuomotor function by exploiting the plasticity of the central nervous system. Integrated with a motion tracking system and an eye tracking device, the interactive virtual environment allows for the creation and manipulation of a wide variety of stimuli, as well as real-time recording of hand-, eye- and body movements and coordination. The goal of the project is to design a cost-effective and efficient vision restoration system.

Investigate the epidemiology of lawn mower-related injuries to children in the US. A retrospective analysis was conducted of children younger than 18years of age treated in US emergency departments for a lawn mower-related injury from 1990 through 2014 using data from the National Electronic Injury Surveillance System. An estimated 212,258 children lawn mower-related injuries from 1990 through 2014, equaling an average annual rate of 11.9 injuries per 100,000 US children. The annual injury rate decreased by 59.9% during the 25-year study period. The leading diagnosis was a laceration (38.5%) and the most common body region injured was the hand/finger (30.7%). Struck by (21.2%), cut by (19.9%), and contact with a hot surface (14.1%) were the leading mechanisms of injury. Patients Lawn mower-related injuries continue to be a cause of serious morbidity among children. Although the annual injury rate decreased significantly over the study period, the number of injuries is still substantial, indicating the need for additional prevention efforts. In addition to educational approaches, opportunities exist for improvements in mower design and lawn mower safety standards. Copyright © 2017 Elsevier Inc. All rights reserved.

Hand and foot burns in children are difficult to dress. The authors have developed a soft casting technique to manage burns to these areas. The aim of this study is to report the outcomes using weekly dressing changes with a soft casting technique to manage pediatric hand and foot burns in the outpatient setting. A retrospective chart review was performed on children with burns to the hands or feet, who underwent dressing changes with a soft casting technique at the Children's Hospital Colorado Burn Center. Soft casting was performed by placing antibiotic ointment-impregnated nonadherent gauze over the burn wound(s), wrapping the extremity using rolled gauze, applying soft cast pad, plaster, soft cast tape, and an elastic bandage. This was changed weekly. Two hundred ninety-eight children with hand burns had a mean age of 16.8 ± 2 months. Two hundred forty-eight children had partial thickness burn injuries (83%), 50 had full thickness burn injuries (17%), and the mean total body surface area (TBSA) was 1 ± 2.4%. The mean time to heal was 10.1 ± 1.7 days for all subjects. Sixty-six children with foot burns were identified with a mean age of 24 ± 2.6 months. Forty-six children had partial thickness injuries (70%), 20 had full thickness burn injuries (30%), and the mean TBSA was 2.3 ± 2.9%. The mean time to heal was 14.1 ± 2.2 days for all subjects. Weekly dressing changes using a soft casting technique are effective for the outpatient management of pediatric hand and foot burns. This method avoids costly inpatient hospital care, reduces the number of painful dressing changes, and allows children to heal in their own environment.

An essential assumption of injury prevention programs is the common cause hypothesis that the causal pathways of near misses and minor injuries are similar to those of major injuries. The rates of near miss, minor injury and major injury of all reported incidents and musculoskeletal incidents (MSIs) were calculated for three health regions using information from a surveillance database and productive hours from payroll data. The relative distribution of individual causes and activities involved in near miss, minor injury and major injury were then compared. For all reported incidents, there were significant differences in the relative distribution of causes for near miss, minor, and major injury. However, the relative distribution of causes and activities involved in minor and major MSIs were similar. The top causes and activities involved were the same across near miss, minor, and major injury. Finding from this study support the use of near miss and minor injury data as potential outcome measures for injury prevention programs. (c) 2008 Wiley-Liss, Inc.

Inhalation but not transdermal resorption of hand sanitizer ethanol causes positive ethyl glucuronide findings in urine.

Ethyl glucuronide (EtG) in urine is considered a specific marker of recent ethanol consumption. There is an ongoing debate about whether inhalation or transdermal resorption of sanitizer ethanol is the underlying cause for positive EtG findings after hand disinfection. Desderman(®) pure (Schülke & Mayr GmbH, Norderstedt) with 78.2g 96% (v/v) ethanol/100g and approx. 10% 2-propanol was used for multiple hand disinfection without and under an exhauster. Simulating a common working day in a clinic, 5 co-workers of our lab used the sanitizer 32 fold within 8h and 2 persons were merely exposed to the sanitizer vapor but without any dermal sanitizer contact. Any additional ethanol intake or exposition was reliably excluded. Spot urine was collected at baseline, after 1, 2, 4, 6 … 14, and finally 24h after the first sanitizer use. A validated LC-MS/MS was used for MRM and MS(3) of EtG and qualitative analyses of ethyl sulfate and 2-propyl glucuronide. Multiple hand disinfection caused positive EtG findings of up to 2.1mg/L or 1.7mg/g creatinine in 4 out of 5 test persons and even of 0.6mg/L or 0.8mg/g for 2 controls which were merely exposed to the sanitizer vapor but without any sanitizer contact. EtG results between the clinical (0.5mg/g) and the forensic (0.1mg/g) cut-off were obtained even 6h after the last sanitizer exposition. An exhauster prevented the sanitizer vapor inhalation and reduced the EtG excretion to mostly below the detection limit of 0.02mg/g. The maximum value was 0.09mg/g. Ethyl sulfate and 2-propyl glucuronide (2-PpG) were detectable only in the EtG positive samples. 2-PpG is a metabolite of 2-propanol, which is quite frequently used in disinfectants. Thus, the detection of this substance can be used in cases of odd EtG results as an indicator of (unintended) sanitizer exposition. Ethanol from hand sanitizers is predominantly incorporated by the respiratory tract but not via the skin. It can cause a distinct ethyl glucuronide excretion and thus

We studied lung clearance of aerosolized technetium-labeled diethylenetriamine pentaacetic acid (/sup 99m/TcDTPA), plasma concentrations of 6-keto-PGF1 alpha and thromboxane B2, and pulmonary edema as indices of lung injury in rabbits exposed to cigarette smoke (CSE). Forty-six rabbits were randomly assigned to 4 groups: control sham smoke exposure (SS, N = 9), sham smoke exposure ibuprofen-pretreated (SS-I, N = 10), CSE (N = 9), sham smoke exposure ibuprofen-pretreated (SS-I, N = 10), CSE (N = 9), and CSE ibuprofen-pretreated (CSE-I, N = 19). Ibuprofen (cyclooxygenase eicosanoid inhibitor) was administered as a single daily intramuscular injection (25 mg/kg) for 7 days before the experiment. Cigarette or sham smoke was delivered by syringe in a series of 5, 10, 20, and 30 tidal volume breaths with a 15-min counting period between each subset of breaths to determine /sup 99m/TcDTPA biological half-life (T1/2). In the ibuprofen pretreated group, CSE caused significant decreases in /sup 99m/TcDTPA T1/2 and dynamic lung compliance. Furthermore, these changes in lung function were accompanied by severe injury to type I alveolar cell epithelium, pulmonary edema, and frequently death of the rabbits. These findings suggest that inhibition of the cyclooxygenase pathway before CSE exacerbates lung injury in rabbits.

The star fruit belongs to the family Oxalidacea, species Averrhoa carambola. It is rich in minerals, vitamin A, C, B complex vitamins and oxalic acid. Recent studies show that the toxicity of the fruit differs between the patients and may be explained by single biological responses, age, and the intake quantity of the neurotoxin in each fruit in addition to glomerular filtration rate given by each patient. Additionally, the nephrotoxicity caused by the fruit is dose-dependent and may lead to the deposition of crystals of calcium oxalate intratubular, as well as by direct injury to the renal tubular epithelium, leading to apoptosis of the same. We report the case of a patient who after ingestion of the juice and fresh fruit, developed acute renal failure requiring dialysis, evolving with favourable outcome and recovery of renal function.

The relationships of the site of impact to the CT findings and to the severity and outcome of an injury were analysed based on 50 cases of diffuse brain injury (DBI). The CT findings of DBI were classified into 5 types: diffuse cerebral swelling (DCS); isodensity hemispheric swelling (IHS); deep-seated brain injury (DSI); subarachnoid hemorrhage (SAH), and normal finding (N). The sites of the impact were frontal in 19 cases, temporal in 8 cases, parietal in 4 cases, occipital in 12 cases, and multiple or undetermined in 7 cases. Frontal blows resulted in the lowest mortality rate (5.3%); on the other hand, occipital blows resulted in the highest (58%). Additionally, occipital blows caused the highest primary brain-stem injury, i.e., 41.7%. The frontal region was the most common impact area, revealing DCS and N. Temporal blows commonly resulted in DSI. Parietal blows were characteristic causes of IHS cases. However, occipital blows generally demonstrated no specific tendencies with regard to the type of CT finding. Based on this study, it is evident that CT findings and outcomes are influenced by the location of the impact. It is the authors' impression that, in severe head-injury cases, occipital blows, which are usually associated with primary brain-stem injuries, are the most serious. (author)

Full Text Available We performed a 2-year follow-up survey of 523 patients with peripheral nerve injuries caused by the earthquake in Wenchuan, Sichuan Province, China. Nerve injuries were classified into three types: type I injuries were nerve transection injuries, type II injuries were nerve compression injuries, and type III injuries displayed no direct neurological dysfunction due to trauma. In this study, 31 patients had type I injuries involving 41 nerves, 419 had type II injuries involving 823 nerves, and 73 had type III injuries involving 150 nerves. Twenty-two patients had open transection nerve injury. The restoration of peripheral nerve function after different treatments was evaluated. Surgical decompression favorably affected nerve recovery. Physiotherapy was effective for type I and type II nerve injuries, but not substantially for type III nerve injury. Pharmacotherapy had little effect on type II or type III nerve injuries. Targeted decompression surgery and physiotherapy contributed to the effective treatment of nerve transection and compression injuries. The Louisiana State University Health Sciences Center score for nerve injury severity declined with increasing duration of being trapped. In the first year after treatment, the Louisiana State University Health Sciences Center score for grades 3 to 5 nerve injury increased by 28.2% to 81.8%. If scores were still poor (0 or 1 after a 1-year period of treatment, further treatment was not effective.

Plain X-ray films including some special radiographic views are still the basis of the radiological evaluation of injuries of the distal forearm, the wrist, and the hand. Especially, in the diagnosis of fractures of the distal radius the exact positioning of the arm and hand is essential. For the description of fractures of the distal forearm the AO classification of fractures should be used, which is comprehensive and universally applicable. Conventional tomography and computed tomography (CT) of the radio-ulnar joint and the wrist are used in patients with persisting complaints or equivocal findings on plain radiographs, and difficult anatomical situations. Suspected ligamentous injuries of the wrist including tears of the triangular fibrocartilage complex (TFCC) are evaluated by wrist arthrography or magnetic resonance imaging (MRI), the latter requiring a highly skilled imaging and interpretation technique. MRI is the method of choice for the detection of osteonecrosis. Ultrasound examinations are of minor importance in the work up of wrist and hand injuries. (orig.)

BACKGROUND: Astronaut spacewalk training can result in a variety of symptom complaints and possible injuries. This study quantified and characterized signs, symptoms, and injuries resulting from extravehicular activity spacesuit training at NASA's Neutral Buoyancy Laboratory, Johnson Space Center, Houston, TX, immersion facility. METHODS: We identified the frequency and incidence of symptoms by location, mechanisms of injury, and effective countermeasures. Recommendations were made to improve injury prevention, astronaut training, test preparation, and training hardware. At the end of each test, a questionnaire was completed documenting signs and symptoms, mechanisms of injury, and countermeasures. RESULTS: Of the 770 tests, there were 190 in which suit symptoms were reported (24.6%). There were a total of 352 reported suit symptom comments. Of those symptoms, 166 were in the hands (47.16%), 73 were in the shoulders (20.7%), and 40 were in the feet (11.4%). Others ranged from 6.0% to 0.28%, respectively, from the legs, arms, neck, trunk, groin, and head. Causal mechanisms for the hands included moisture and hard glove contacts resulting in fingernail injuries; in the shoulders, hard contact with suit components and strain mechanisms; and in the feet, hard boot contact. The severity of symptoms was highest in the shoulders, hands, and feet. CONCLUSIONS: Most signs and symptoms were mild, self-limited, of brief duration, and were well controlled by available countermeasures. Some represented the potential for significant injury with consequences affecting astronaut health and performance. Correction of extravehicular activity training-related injuries requires a multidisciplinary approach to improve prevention, medical intervention, astronaut training, test planning, and suit engineering.

The pathological characteristics of an extremely high dose radiation in the legs and hands of a patient is reported. the patient was exposed to 192 Ir γ-rays for 9 hours and 20 minutes, the activity of which was 2.76 TBq. The amputations of the right thigh and left forearm had to be performed 8 days after the irradiation and the debridements and skin graftings were performed on the right hand and the inner side of left knee 55 days after the radiation. Microscopically, massive necrosis of cells of the epidermis, cutaneous appendages, hypodermics and skeletal muscles, and hemorrhage in the dermis, hypodermics and skeletal muscles were seen in the local irradiated parts of the right shank. But the arrector pili muscles in the dermis of the right shank remained. On the fingers and the palm of the left hand, vacuolar degeneration and massive necrosis of the cells of epidermis were present with extensive neutrophil infiltration. Cysts of large or small size were formed from the necrotic cells, separating epidermis from dermis. There were degeneration and necrosis of glandular epithelium cells of sweat glands. Hemorrhage was present in dermis and hypodermics. All the hematopoietic tissues in the bone marrow in the upper ends of the tibia and fibula and in the lower ends of the femur, the radius and the ulna disappeared. Acute radiation ulcers were present on the skin of the left knee and on the skin of the thumb, index finger and middle finger of the right hand. The extremely severe acute radiation injury caused by extremely high dose of 192 Ir led to the necrosis of the extensive soft tissues deep to skeletal muscles and the disappearance of the hematopoietic tissues in the bone marrow

The effects of second-hand smoke on biological processes important in atherogenesis

Full Text Available Abstract Background Atherosclerosis is the leading cause of death in western societies and cigarette smoke is among the factors that strongly contribute to the development of this disease. The early events in atherogenesis are stimulated on the one hand by cytokines that chemoattract leukocytes and on the other hand by decrease in circulating molecules that protect endothelial cells (ECs from injury. Here we focus our studies on the effects of "second-hand" smoke on atherogenesis. Methods To perform these studies, a smoking system that closely simulates exposure of humans to second-hand smoke was developed and a mouse model system transgenic for human apoB100 was used. These mice have moderate lipid levels that closely mimic human conditions that lead to atherosclerotic plaque formation. Results "Second-hand" cigarette smoke decreases plasma high density lipoprotein levels in the blood and also decreases the ratios between high density lipoprotein and low density lipoprotein, high density lipoprotein and triglyceride, and high density lipoprotein and total cholesterol. This change in lipid profiles causes not only more lipid accumulation in the aorta but also lipid deposition in many of the smaller vessels of the heart and in hepatocytes. In addition, mice exposed to smoke have increased levels of Monocyte Chemoattractant Protein–1 in circulation and in the heart/aorta tissue, have increased macrophages in the arterial walls, and have decreased levels of adiponectin, an EC-protective protein. Also, cytokine arrays revealed that mice exposed to smoke do not undergo the switch from the pro-inflammatory cytokine profile (that develops when the mice are initially exposed to second-hand smoke to the adaptive response. Furthermore, triglyceride levels increase significantly in the liver of smoke-exposed mice. Conclusion Long-term exposure to "second-hand" smoke creates a state of permanent inflammation and an imbalance in the lipid profile that

EU legislation has reduced the epidemic of nickel contact allergy affecting the consumer, and shifted the focus towards occupational exposure. The acid wipe sampling technique was developed to quantitatively determine skin exposure to metals. To assess the clinical usefulness of the acid wipe sampling technique as part of the diagnostic investigation for occupational nickel allergy-associated hand dermatitis. Six patients with vesicular dermatitis on the hands were included. Acid wipe sampling of skin and patch testing with a nickel sulfate dilution series were performed. Nickel was detected in all samples from the hands. In all patients, the nickel content on the hands was higher than on the non-exposed control area. Occupational exposure to nickel-releasing items raised the nickel content on exposed skin as compared with a non-exposed control site. Nickel-reducing measures led to complete symptom relief in all cases. In cases of a positive nickel patch test reaction and hand eczema, patients should perform the dimethylglyoxime (DMG) test on metallic items at home and at work. The acid wipe sampling technique is useful for the diagnosis of occupational hand eczema following screening with the inexpensive DMG test. © 2010 John Wiley & Sons A/S.

Whiplash injuries.

Whiplash injuries are very common and usually are associated with rear-end collisions. However, a whiplash injury can be caused by any event that results in hyperextension and flexion of the cervical spine. These injuries are of serious concern to all consumers due to escalating cost of diagnosis, treatment, insurance, and litigation. Most acute whiplash injury cases respond well to conservative treatments, which result in resolution of symptoms usually within weeks to a few months after the injury occurred. Chronic whiplash injuries often are harder to diagnose and treat and often result in poor outcomes. Current research shows that various structures in the cervical spine receive nociceptive innervation and potentially may be the cause of chronic pain symptoms. One potential pain generator showing promise is the facet or zygapophyseal joints. Various researchers have proven that these joints are injured during whiplash injuries and that diagnosis and temporary pain relief can be obtained with facet joint injections. The initial evaluation of any patient should follow an organized and stepwise approach, and more serious causes of neck pain must first be ruled out through the history, physical examination, and diagnostic testing. Treatment regimens should be evidence-based, focusing on treatments that have proven to be effective in treating acute and chronic whiplash injuries.

A series of complications caused by enteroviruses, including meningitis, encephalitis, acute flaccid paralysis, acute cardiopulmonary failure, respiratory infection, and myocardial injury have been reported in hand, foot and mouth disease/herpangina (HFMD/HA). However, the complication of diarrhoea caused by enteroviruses has been neglected, and a summary of its clinical features and impact on HFMD/HA is unavailable. We included inpatients with HFMD/HA admitted to the Paediatric Department of Zhujiang Hospital during 2009-2012. We summarised and compared clinical data for cases with and without diarrhoea, and determined enterovirus serotypes by reverse transcriptase polymerase chain reaction and genotyping based on a partial-length fragment of viral protein 1 or the 5'-untranslated region. There were 804 inpatients with HFMD/HA and 28 (3.5%) presented with diarrhoea. Gastrointestinal symptoms were mild in most cases of diarrhoea (82.1%), with high prevalence of no dehydration (82.1%), short duration of diarrhoea (78.6%) and watery stools (75.0%). The prevalence of multi-organ dysfunction syndrome (10.7 vs 0.40%) (p = 0.001), hepatic injury (14.3 vs 3.4%) (p = 0.019), myocardial injury (21.4 vs 6.1%) (p = 0.002) and convulsion (21.4 vs 7.2%) (p = 0.016) was significantly higher in the diarrhoea than no diarrhoea group. There was no significant difference between the two groups regarding prevalence of death, altered consciousness, paralysis, central nervous system involvement, or acute respiratory infection. Most patients with diarrhoea caused by enteroviruses circulating in Guangdong Province in 2009-2012 had mild or moderate gastrointestinal symptoms. Although enterovirus-related diarrhoea caused additional multi-organ dysfunction syndrome, hepatic injury and myocardial injury in children with HFMD/HA, timely intervention efficiently reduced disease severity and improved outcome.

J Strength Cond Res 23(7): 2054–2060, 2009—Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for “Weightlifting.” Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as “accidental” if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4, 111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p injuries (n = 2, 565) showed that the oldest categories (19–22 and 23–30 yr) demonstrated a greater percentage of sprains and strains relative to younger age categories (p injuries sustained in the 8 to 13 group were to the hand and foot and were most often related to “dropping” and “pinching” in the injury descriptions, and there was an increased percentage of fractures in the 8 to 13 group relative to all other groups (p injuries are the result of accidents that are potentially

Cerebral Palsy (CP) is the leading cause of childhood motor disability, with a global incidence of 1.6 to 2.5/1,000 live births. Approximately 23% of children with CP are dependent upon assistive technologies. Some children with developmental disabilities have self-injurious behaviors such as finger biting but also have therapeutic needs. The purpose of this technical note is to describe design considerations for a protective glove and finger covering that maintains finger dexterity for children who exhibit finger and hand chewing (dermatophagia) and require therapeutic range of motion and may benefit from sensory stimulation resulting from constant contact between glove and skin. Protecting Little and Adolescent Youth (PLAY) Hands are protective gloves for children with developmental disorders such as CP who injure themselves by biting their hands due to pain or sensory issues. PLAY Hands will be cosmetically appealing gloves that provide therapeutic warmth, tactile sensory feedback, range of motion for donning/ doffing, and protection to maximize function and quality of life for families of children with developmental disorders. The technology is either a per-finger protective orthosis or an entire glove solution designed from durable 3D-printed biodegradable/bioabsorbable materials such as thermoplastics. PLAY Hands represent a series of protective hand wear interventions in the areas of self-mutilating behavior, kinematics, and sensation. They will be made available in a range of protective iterations from single- or multi-digit finger orthoses to a basic glove design to a more structurally robust and protective iteration. To improve the quality of life for patients and caregivers, they are conceptualized to be cosmetically appealing, protective, and therapeutic.

The running portion of the triathlon represents the final leg of the competition and, by some reports, the most important part in determining a triathlete's overall success. Although most triathletes spend most of their training time on cycling, running injuries are the most common injuries encountered. Common causes of running injuries include overuse, lack of rest, and activities that aggravate biomechanical predisposers of specific injuries. We discuss the running-associated injuries in the hip, knee, lower leg, ankle, and foot of the triathlete, and the causes, presentation, evaluation, and treatment of each.

The popularity of bicycle riding for recreation, exercise and transportation has grown enormously in recent years, which has led to an increased incidence of bicycle-related injuries. While these injuries involve mainly the musculoskeletal system, data on shoulder-specific injuries incurred while bike riding are lacking. Classifying these shoulder injuries may provide insight and assistance in the creation and implementation of effective protective gear and measures. To investigate the types and mechanisms of shoulder injuries among cyclists. This study retrospectively examined all cyclists who incurred shoulder injuries while riding and were admitted to the emergency department and shoulder clinic between January 2008 and November 2013. The study included 157 subjects with various bicycle-related shoulder injuries treated with either conservative or surgical measures. Eighty-four percent of injuries were caused by a direct blow to the shoulder, 7% by falling on an outstretched hand, 6% were traction injuries, and 3% were due to hyperabduction. Nine different clinical types of injury were observed; the most common injuries were clavicle fractures (32%), followed by acromioclavicular joint dislocations (22%), rotator cuff tears (22%), and humeral fractures (8%). Fifty-one percent of subjects were managed with conservative care and the remaining patients required surgical interventions. Shoulder injuries incurred while riding a bicycle span the entire spectrum of shoulder injuries and often result in debilitating conditions. Although the use of helmets is increasing, there is currently no effective protective gear or measures to prevent riders from suffering shoulder injuries.

Explaining away the body: experiences of supernaturally caused touch and touch on non-hand objects within the rubber hand illusion.

Full Text Available In rubber hand illusions and full body illusions, touch sensations are projected to non-body objects such as rubber hands, dolls or virtual bodies. The robustness, limits and further perceptual consequences of such illusions are not yet fully explored or understood. A number of experiments are reported that test the limits of a variant of the rubber hand illusion.A variant of the rubber hand illusion is explored, in which the real and foreign hands are aligned in personal space. The presence of the illusion is ascertained with participants' scores and temperature changes of the real arm. This generates a basic illusion of touch projected to a foreign arm. Participants are presented with further, unusual visuotactile stimuli subsequent to onset of the basic illusion. Such further visuotactile stimulation is found to generate very unusual experiences of supernatural touch and touch on a non-hand object. The finding of touch on a non-hand object conflicts with prior findings, and to resolve this conflict a further hypothesis is successfully tested: that without prior onset of the basic illusion this unusual experience does not occur.A rubber hand illusion is found that can arise when the real and the foreign arm are aligned in personal space. This illusion persists through periods of no tactile stimulation and is strong enough to allow very unusual experiences of touch felt on a cardboard box and experiences of touch produced at a distance, as if by supernatural causation. These findings suggest that one's visual body image is explained away during experience of the illusion and they may be of further importance to understanding the role of experience in delusion formation. The findings of touch on non-hand objects may help reconcile conflicting results in this area of research. In addition, new evidence is provided that relates to the recently discovered psychologically induced temperature changes that occur during the illusion.

To review the current evidence for the epidemiology of pediatric injuries in martial arts. The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure. Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

The purpose of this study was to provide new insight into the etiology of primarily nonfatal, work-related electrical injuries. We developed a multistage, case-selection algorithm to identify electrical-related injuries from workers' compensation claims and a customized coding taxonomy to identify pre-injury circumstances. Workers' compensation claims routinely collected over a 1-year period from a large U.S. insurance provider were used to identify electrical-related injuries using an algorithm that evaluated: coded injury cause information, nature of injury, "accident" description, and injury description narratives. Concurrently, a customized coding taxonomy for these narratives was developed to abstract the activity, source, initiating process, mechanism, vector, and voltage. Among the 586,567 reported claims during 2002, electrical-related injuries accounted for 1283 (0.22%) of nonfatal claims and 15 fatalities (1.2% of electrical). Most (72.3%) were male, average age of 36, working in services (33.4%), manufacturing (24.7%), retail trade (17.3%), and construction (7.2%). Body part(s) injured most often were the hands, fingers, or wrist (34.9%); multiple body parts/systems (25.0%); lower/upper arm; elbow; shoulder, and upper extremities (19.2%). The leading activities were conducting manual tasks (55.1%); working with machinery, appliances, or equipment; working with electrical wire; and operating powered or nonpowered hand tools. Primary injury sources were appliances and office equipment (24.4%); wires, cables/cords (18.0%); machines and other equipment (11.8%); fixtures, bulbs, and switches (10.4%); and lightning (4.3%). No vector was identified in 85% of cases. and the work process was initiated by others in less than 1% of cases. Injury narratives provide valuable information to overcome some of the limitations of precoded data, more specially for identifying additional injury cases and in supplementing traditional epidemiologic data for further

Firework related injury and legislation: the epidemiology of firework injuries and the effect of legislation in Northern Ireland.

Fogarty, B J; Gordon, D J

1999-02-01

The efficacy of legislation in reducing firework associated injuries is uncertain as is the nature of the problem within the United Kingdom (UK). In September 1996 the legislation governing firework sale in Northern Ireland was relaxed thus equalling that of the rest of the UK. For the 2 years following the change in legislation we prospectively assessed those patients who were admitted with a firework injury over the Halloween period. We then compared these results with retrospective data for the 3 years prior to the change in firework law. In the pre-legislation series the mean number of patients admitted annually was 0.38 per 100,000 while in the post-legislation series the mean was 0.43 per 100,000. Blast injury to the hand was the commonest injury accounting for 53% of cases in both series. Burn injuries were the second commonest form of injury comprising 30% of all admissions. Of those admitted with a hand injury 47% had at least one finger terminalised and nearly half of those patients admitted with burns (44%) required skin grafting. We conclude that early evidence suggests that liberalisation of the law on firework sale has not resulted in a significant increase in firework related injuries requiring hospital admission.

Powerlifting is a discipline of competitive weightlifting. To date, no investigations have focused on pain encountered during routine training. The aim of the study was to identify such pain, assign it to particular exercises and assess the data regarding injuries as well as the influence of intrinsic and extrinsic factors. Data of 245 competitive and elite powerlifters was collected by questionnaire. Information regarding current workout routines and retrospective injury data was collected. Study subjects were selected from 97 incorporated powerlifting clubs. A percentage of 43.3% of powerlifters complained of problems during routine workouts. Injury rate was calculated as 0.3 injuries per lifter per year (1 000 h of training=1 injury). There was no evidence that intrinsic or extrinsic factors affected this rate. Most commonly injured body regions were the shoulder, lower back and the knee. The use of weight belts increased the injury rate of the lumbar spine. Rate of injury to the upper extremities was significantly increased based on age >40 years (shoulder/p=0.003, elbow/p=0.003, hand+wrist/p=0.024) and female gender (hand+wrist/p=0.045). The daily workout of a large proportion of powerlifters is affected by disorders which do not require an interruption of training. The injury rate is low compared to other sports. © Georg Thieme Verlag KG Stuttgart · New York.

Transplantation of human embryonic stem cell-derived oligodendrocyte progenitors into rat spinal cord injuries does not cause harm.

Demyelination contributes to loss of function following spinal cord injury. We have shown previously that transplantation of human embryonic stem cell-derived oligodendrocyte progenitors into adult rat 200 kD contusive spinal cord injury sites enhances remyelination and promotes recovery of motor function. Previous studies using oligodendrocyte lineage cells have noted a correlation between the presence of demyelinating pathology and the survival and migration rate of the transplanted cells. The present study compared the survival and migration of human embryonic stem cell-derived oligodendrocyte progenitors injected 7 days after a 200 or 50 kD contusive spinal cord injury, as well as the locomotor outcome of transplantation. Our findings indicate that a 200 kD spinal cord injury induces extensive demyelination, whereas a 50 kD spinal cord injury induces no detectable demyelination. Cells transplanted into the 200 kD injury group survived, migrated, and resulted in robust remyelination, replicating our previous studies. In contrast, cells transplanted into the 50 kD injury group survived, exhibited limited migration, and failed to induce remyelination as demyelination in this injury group was absent. Animals that received a 50 kD injury displayed only a transient decline in locomotor function as a result of the injury. Importantly, human embryonic stem cell-derived oligodendrocyte progenitor transplants into the 50 kD injury group did not cause a further decline in locomotion. Our studies highlight the importance of a demyelinating pathology as a prerequisite for the function of transplanted myelinogenic cells. In addition, our results indicate that transplantation of human embryonic stem cell-derived oligodendrocyte progenitor cells into the injured spinal cord is not associated with a decline in locomotor function.

Purpose-designed compliant flooring and carpeting have been promoted as a means for reducing fall-related injuries in high-risk environments, such as long-term care. However, it is not known whether these surfaces influence the forces that long-term care staff exert when pushing residents in wheelchairs. We studied 14 direct-care staff who pushed a loaded wheelchair instrumented with a triaxial load cell to test the effects on hand force of flooring overlay (vinyl versus carpet) and flooring subfloor (concrete versus compliant rubber [brand: SmartCells]). During straight-line pushing, carpet overlay increased initial and sustained hand forces compared to vinyl overlay by 22-49% over a concrete subfloor and by 8-20% over a compliant subfloor. Compliant subflooring increased initial and sustained hand forces compared to concrete subflooring by 18-31% when under a vinyl overlay. In contrast, compliant flooring caused no change in initial or sustained hand forces compared to concrete subflooring when under a carpet overlay. Copyright © 2018 Elsevier Ltd. All rights reserved.

Specimens and clinical data were collected from 243 hand, foot and mouth disease patients in Beijing in 2013. In total, 130 stool specimens were genotyped for enterovirus. Hand, foot and mouth disease was mainly detected in suburban areas and at the edges of urban areas between May and August. Coxsackievirus (CV) A6 replaced enterovirus (EV) 71 and CVA16, becoming the main causative agent of hand, foot and mouth disease. CVA6 infection led to significantly reduced fever duration and glucose levels compared with EV71 infection.

Nonanastomotic strictures (NAS) are common biliary complications after liver transplantation (LT). Delayed rearterialization induces biliary injury in several hours. However, whether this injury can be prolonged remains unknown. The correlation of this injury with NAS occurrence remains obscure. Different delayed rearterialization times were compared using a porcine LT model. Morphological and functional changes in bile canaliculus were evaluated by transmission electron microscopy and real-time PCR. Immunohistochemistry and TUNEL were performed to validate intrahepatic bile duct injury. Three months after LT was performed, biliary duct stricture was determined by cholangiography; the tissue of common bile duct was detected by real-time PCR. Bile canaliculi were impaired in early postoperative stage and then exacerbated as delayed rearterialization time was prolonged. Nevertheless, damaged bile canaliculi could fully recover in subsequent months. TNF-α and TGF-β expressions and apoptosis cell ratio increased in the intrahepatic bile duct only during early postoperative period in a time-dependent manner. No abnormality was observed by cholangiography and common bile duct examination after 3 months. Delayed rearterialization caused temporary injury to bile canaliculi and intrahepatic bile duct in a time-dependent manner. Injury could be fully treated in succeeding months. Solo delayed rearterialization cannot induce NAS after LT. © 2014 The Authors. Transplant International published by John Wiley & Sons Ltd on behalf of Steunstichting ESOT.

Injury of young cucumber plants caused by dust containing fluorine emitted by industrial concerns; changes in the green leaf pigments

Particulates containing fluorine obtained at an aluminum production facility were applied at a rate of 1 gram per square meter to the cotyledons of cucumber plants, and caused (sequentially) acute and chronic injury. Reduced chlorophyll content was correlated with the acute phase, and retardation of normal chlorophyll degradation was correlated with the chronic phase. The true leaves, which did not come into direct contact with the particulates, displayed chronic injury symptoms, the most noticeable of which was reduced growth. Pigment content of experimental plants was lower than controls. Overhead watering caused more severe symptom development of symptoms than did watering the soil. 6 references, 1 figure, 1 table.

OBJECTIVE To characterize and compare injuries found in dogs involved in spontaneously occurring dogfights with those of dogs used in illegal organized dogfighting. DESIGN Retrospective case-control study. ANIMALS 36 medium-sized dogs evaluated following spontaneous fights with a dog of the same sex and similar weight (medium dog-medium dog [MDMD] fights), 160 small dogs examined following spontaneous fights with a larger dog (big dog-little dog [BDLD] fights), and 62 dogs evaluated after being seized in connection with dogfighting law enforcement raids. PROCEDURES Demographic characteristics and injuries were recorded from medical records. Prevalence of soft tissue injuries in predetermined body surface zones, as well as dental or skeletal injuries, was determined for dogs grouped by involvement in BDLD, MDMD, and organized dogfights. The extent of injuries in each location was scored and compared among groups by 1-factor ANOVA. Patterns of injuries commonly incurred by each group were determined by use of prevalence data. RESULTS Mean extent of injury scores differed significantly among groups for all body surface zones except the eye and periorbital region. Mean scores for dental injuries and rib fractures also differed significantly among groups. Organized fighting dogs more commonly had multiple injuries, particularly of the thoracic limbs, dorsal and lateral aspects of the head and muzzle or oral mucosa, dorsal and lateral aspects of the neck, and ventral neck and thoracic region. CONCLUSIONS AND CLINICAL RELEVANCE To the authors' knowledge, this was the first study to compare injuries incurred during spontaneous and organized dogfighting. Establishing evidence-based patterns of injury will help clinicians identify dogs injured by organized dogfighting and aid in the prosecution of this crime.

Hand osteoarthritis: diagnosis, pathogenesis, treatment

Full Text Available Due to the development of synovitis, early-stage hand osteoarthritis (HOA mimics hand joint injury in rheumatoid arthritis (RA. However, the topography of synovitis is diverse in these diseases:  distal interphalangeal and thumb joints are involved in the process in HOA. In the latter, tests are negative for immunological markers  (anti-cyclic citrullinated peptide antibodies, which is typical of RA.  The differences between HOA and RA are prominent, as evidenced  by hand X-rays and magnetic resonance imaging. Investigations  suggest that cytokine profile imbalance is implicated in the  pathogenesis of osteoarthritis, which brings it closer to RA. However, therapy for HOA has not been practically developed; there are only a few works on the use of disease-modifying antirheumatic drugs and  biological agents in these patients. It is necessary to work out Russian guidelines for the treatment of HOA.

In Turkey, the construction sector is responsible for the largest number of work-related fatalities among all industries. This study's objective is to determine the characteristics of the fatalities in the construction sector in Kocaeli Province. The study was carried out retrospectively by investigating the records of occupational deaths between 1990 and 2001 in the Kocaeli District of Turkey. Fatal occupational injuries in the construction sector were investigated in detail by evaluating the records. The analysis was based on data from 153 deaths. The incidence of occupational injuries was found overall to be 4.5% in Kocaeli, while the annual mortality rate was 60.4 in Kocaeli and 79.0 in Turkey per 100,000 workers over the entire time period. On the other hand, the fatality rate of occupational injuries was found to be 12.0 per 1,000 in Turkey and 6.4 per 1,000 in Kocaeli. The evaluation of the type of injuries in construction sector has revealed that in 69 of cases (45.1%) fell down from high altitude, in 22 cases (14.4%) vehicle accident, and in 22 (14.4%) electrocution were the cause of death. The leading causes of death have been found to be blunt-force trauma (37.9%) and head trauma (25.5%). Fourty one percent of those who had occupational accidents have had less than one year work experience. Only in 7.8% of deaths, the cause was determined through an autopsy.

Hand, foot and mouth disease (HFMD) is usually caused by coxsackievirus A16 or enterovirus 71 (EV71). Between 2011 and 2013, HFMD cases were reported from different Cuban provinces. A total of 42 clinical specimens were obtained from 23 patients. Detection, identification and phylogenetic analysis of enterovirus-associated HFMD were carried out by virus isolation, specific enterovirus PCR and partial VP1 sequences. HEV was detected in 11 HFMD cases. Emerging genetic variants of coxsackievirus A6 and EV71 were identified as the causative agents of the Cuban HFMD cases.

Full Text Available Brazilian jiu-jitsu (BJJ is a martial art that focuses on groundwork, joint locks, and chokeholds. The purpose of this study is to determine the prevalence of injuries sustained during BJJ training. A 27-question research survey was e-mailed to 166 BJJ gyms in the United States. Demographic information, belt level, weight class, training hours, competition experience, and injury prevalence data were collected. The majority of respondents were Caucasian (n = 96 males (n = 121 with an average age of 30.3 years. Overall, the most common injury locations were to the hand and fingers (n = 70, foot and toes (n = 52, and arm and elbow (n = 51. The most common medically diagnosed conditions were skin infections (n = 38, injuries to the knee (n =26, and foot and toes (n = 19. The most common non-medically diagnosed injuries occurred to the hand and fingers (n = 56, arm and elbow (n = 40, and foot and toes (n = 33. In general, athletes were more likely to sustain distal rather than proximal injuries. Athletes reported more frequent medically diagnosed injuries to the lower extremity and more frequent self-diagnosed injuries to the upper extremity. Upper extremity injuries appear to be more frequent but less severe than lower extremity injuries with the opposite being true for lower extremity injuries.

We aimed to determine the causes ofileal injury in two models of microbial sepsis resulted from infectionwith Aeromonas hydrophila or its endotoxin. We alsoevaluated the protective effect of phytic acid.Methods: Thin sections of ileum from 60 Swiss male mice incontrol, bacteria-infected or lipopolysaccharides (LPS andbacteria-infected or LPS-infected co-administered with phyticacid were subjected to histopathological and TdT-mediateddUTP nick-end labeling (TUNEL assay for apoptotic cellsdetection while ultra thin sections were stained with uranylacetate and lead citrate for cytological changes examination.Also, ileum images were exposed to the image analysis softwareto determine some related morphometric measures.Results: Necrosis and apoptosis were observed in ileum injuryin both examined sepsis models. The ileum injury was moresevere in LPS model. Phytic acid showed the ability to attenuateileum injury in Aeromonas hydrophila and its endotoxinmodels of sepsis after four weeks administration where itssupplementation significantly minimized the histopathologicaland cytological complications and morphometric alterationsresulted from the injury.Conclusion: The protective effects of phytic acid may becaused by increased mucous secretion, decreased apoptoticindex, attenuating the inflammatory and lymphocytic cellscount or increasing the renewal of the crypt cells and villousepithelial cells proliferation.

Acute Compartment Syndrome Which Causes Rhabdomyolysis by Carbon Monoxide Poisoning and Sciatic Nerve Injury Associated with It: A Case Report.

Science.gov (United States)

Ji, Jung-Woo

2017-09-01

Rhabdomyolysis is most frequently caused by soft tissue injury with trauma to the extremities. Non-traumatic rhabdomyolysis may be caused by alcohol or drug abuse, infection, collagen disease, or intensive exercise, but incidence is low. In particular, rhabdomyolysis resulting from carbon monoxide poisoning is especially rare. If caught before death, carbon monoxide poisoning has been shown to cause severe muscle necrosis and severe muscle damage leading to acute renal failure. In cases of carbon-monoxide-induced rhabdomyolsis leading to acute compartment syndrome in the buttocks and sciatic nerve injury are rare. We have experience treating patients with acute compartment syndrome due to rhabdomyolysis following carbon monoxide poisoning. We report the characteristic features of muscle necrosis observed during a decompression operation and magnetic resonance imaging findings with a one-year follow-up in addition to a review of the literature.

To survey the American Society for Surgery of the Hand membership to determine the nature and distribution of nerve injuries treated after elbow arthroscopy. An online survey was sent to all members of the American Society for Surgery of the Hand under an institutional review board-approved protocol. Collected data included the number of nerve injuries observed over a 5-year period, the nature of treatment required for the injuries, and the outcomes observed after any intervention. Responses were anonymous, and results were securely compiled. We obtained 372 responses. A total of 222 nerve injuries were reported. The most injured nerves reported were ulnar, radial, and posterior interosseous (38%, 22%, and 19%, respectively). Nearly half of all patients with injuries required operative intervention, including nerve graft, tendon transfer, nerve repair, or nerve transfer. Of the patients who sustained major injuries, those requiring intervention, 77% had partial or no motor recovery. All minor injuries resolved completely. Our results suggest that major nerve injuries after elbow arthroscopy are not rare occurrences and the risk of these injuries is likely under-reported in the literature. Furthermore, patients should be counseled on this risk because most nerve injuries show only partial or no functional recovery. With the more widespread practice of elbow arthroscopy, understanding the nature and sequelae of significant complications is critically important in ensuring patient safety and improving outcomes.

The purpose of this study was to analyze traumatic dental injuries in children visiting the dental hospital emergency department in Samsun of Turkey, in the period from 2007 to 2011. Data of age, gender, causes of dental trauma, injured teeth, type of dental injuries, the application period, the dental treatments, and traumatic dental injuries according to the seasons were obtained from the records at dental hospital. Of all 320 patients with traumatic dental injury, 205 were boys and 115 were girls with a boys/girls ratio 1.78:1. Traumatic dental injury was observed more frequently in the 7-12 age groups: 52.5% in girls and 67.8% in boys. Falls are the major cause of traumatic dental injury in the age group 6-12 (51.4%). Sport activities are a common cause of traumatic dental injury in the 7-12 age group (34.2%). Patients visited a dentist within approximately 2 h (57.1%). The upper anterior teeth were subjected to trauma more frequently than the lower anterior teeth. The maxillary central incisors were the most commonly affected teeth, and the mandibular canins were the least affected teeth. In primary teeth, avulsion was the most common type of dental injury (23%); on the other hand, enamel fractures were the most common type of dental injury (30.6%) observed in permanent teeth. In the primary dentition, the most commonly performed treatments were dental examination and prescribing (70%). The most common treatment choices in permanent teeth were restoration and dental examination (49.7 and 15.8%, respectively). The results of the study show that the emergency intervention to traumatized teeth is important for good prognosis of teeth and oral tissues. Therefore, the parents should be informed about dental trauma in schools, and dental hospital physicians should be subjected to postgraduate training.

A dance floor is often the only support of movements in dance. A dance floor surface that shows deficiencies, can result in acute injuries and chronic problems. Although the significance of an adequate dance floor is well known, there is still a lack of differentiated analyses of dance floor-related acute injuries. This study presents data on acute injuries exclusively caused by the dance floor. The data were obtained from standardized work accident reports from consultants (F 1000), documentary accident records from all Berlin theatres, a state ballet school (n=2,281), and case records from the Berlin State Accident Insurance (UKB) covering a period of 17 years. All analyses and descriptive statistics were conducted with Excel 2007 and SPSS 18. Dance floor surfaces were the causative factor in 12.8% of all accidents (n=291, female 183, male 108). Almost two thirds (62.6%) of all accidents in professional dancers happened on stage, and almost half (49.5%) occurred during performances. As for causative factors, 53.1% of the professional dancers (P) and 42.5% of the dance students (S) claimed that the floor had been "too slippery," with "getting stuck" or (tripping) as the second most common problem (P 18.4%, S 11.3%). Of the injured dancers, 41.8% were older than 30 years and can therefore be categorized as experienced. Dance floors play a significant role in the occurrence of acute injuries, even in experienced dancers. Performances on stage seem to be a particular risk. However, injury prevention measures should include all work locations (P) as well as non-dance-specific locations (S).

Athletes typically maintain rigorous training and work programs to be able to participate in competitions. An injury that occurs during the competition that causes withdrawal from the competition and a possible departure from sports, can render results athletes' and their support staff's efforts as meaningless. The early detection of injuries in the competition and developing preventive training programs can help ensure that participating in competitions and the associated preparatory efforts are not wasted. In this study, the sports injuries discussed occurred during training and competition events of the Turkish Shooting Sportive group. Body parts of injuries are determined and exercise programs focused on the affected body parts are developed. A total of 729 athletes (285 female, 444 male) who participated in Turkish Shooting Sports Championship during the 2010-2011 competition period participated in the study. Athletes were given a questionnaire that was developed prior to the event, and the questionnaire was filled in during interviews conducted one-on-one. Data was collected from the questionnaire and SPSS v.16.0 was used to analyze the results. The study was completed in six months. The results showed that the most of the injuries that occurred during training were strain and muscle tears whereas most of the injuries occurred during the actual competition were strain, muscle tears, tendinitis, and sprain. The results also indicated that during training, the most frequently-occurring injuries were in shoulder, calf-thigh, hand and wrist; whereas during the competition, it was manifested in the shoulder, foot and ankle. Muscle strengthening, stretching and proprioception exercises for these body parts should be included as part of the athletic training program.

Introduction With more than 10 million of daily users, e-cigarettes encountered a great success. But in the past few years, the number of medical reports of injuries caused by the explosion of e-cigarettes has significantly increased. This article aims at reporting our series and reviewing the literature to propose a new classification based on the mechanisms of injuries related to e-cigarettes that can guide non-specialists and specialists in the management of these patients. Method We performed a retrospective review of our institutional burn database from June 2016 to July 2017 for injuries caused by or in the context of using an e-cigarette. The patients' demographics (age, gender), burn injury mechanisms, depth, localization, surface and interventions were described. Results Ten patients suffered from burns related to the use of e-cigarettes. The burns were located at the thigh (80%) and the hand (50%) with a mean surface of 3% of TBSA. Four different mechanisms could be described: Type A: thermal burns with flames due to the phenomenon of "thermal runaway", Type B: blasts lesions secondary to the explosion, Type C: chemical alkali burns caused by spreading of the electrolyte solution and Type D: thermal burns without flames due to overheating. These different mechanisms suggest specific surgical and non-surgical management. Conclusion Management of injuries sustained from e-cigarettes' explosions should be approached from the standpoint of mechanisms. Different mechanisms could be associated and should be considered in specific management. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

This study assessed the relationships of job tasks and living conditions with occupational injuries among coal miners. The sample included randomly selected 516 underground workers. They completed a standardized self-administred questionnaire. The data were analyzed via logistic regression method. The rate of injuries in the past two years was 29.8%. The job tasks with significant crude relative risks were: power hammer, vibrating hand tools, pneumatic tools, bent trunk, awkward work posture, heat, standing about and walking, job tasks for trunk and upper/lower limbs, pain caused by work, and muscular tiredness. Logistic model shows a strong relationship between the number of job tasks (JT) and injuries and significant ORs=1.71 for face work, not-good-health-status, and psychotropic drug use. Musculoskeletal disorders and certain personality traits were also significant in univariate analysis. Therefore job tasks and living conditions strongly increase the injuries, and occupational physicians could help workers to find remedial measures.

The Effect of Antibacterial Formula Hand Cleaners on the Elimination of Microbes on Hands

Coleman, J. R.

2002-05-01

: The purpose of this project is to find out which one of the antibacterial hand cleanser (antibacterial bar soap, antibacterial liquid hand soap, and liquid hand sanitizer) is more effective in eliminating microbes. If antibacterial- formula liquid hand soap is used on soiled hands, then it will be more effective in eliminating microbes. Germs are microorganisms that cause disease and can spread from person-to-person. Bacteria are a kind of microbe, an example of which is Transient Flora that is often found on hands. Hand washing prevents germs from spreading to others. During the procedure, swabs were used to take samples before and after the soiled hands had been washed with one of the antibacterial hand cleansers. Nutrient Easygel was poured into petri dishes to harden for 1 day, and then samples were swabbed on the gel. The Petri dishes were placed in an incubator for 24 hours, and then data was recorded accordingly. The antibacterial liquid hand soap was sufficient in eliminating the majority of bacteria. The hands had 65% of the bacteria on them, and after the liquid hand soap was used only 37% of the bacteria remained.

Paulo Afonso Martins Abati

Full Text Available Abstract INTRODUCTION Freshwater stingray envenomations are an important cause of morbidity in riverine populations living in various regions of Brazil. The sequelae include temporary or permanent disability. This study aimed to identify sociodemographic, clinical, and therapeutic aspects related to stingray injuries in such populations. METHODS This cross-sectional study was conducted in the Extractive Reserve of Tapajos-Arapiuns, located in the municipalities of Santarém and Aveiro (Pará State. A convenience sample comprising 300 local adults was used to obtain data by means of a questionnaire/ interview. RESULTS Overall, 19 (6.3% participants reported having sustained a stingray injury in the 12 months prior to the study. All 19 were injured either while fishing (n=13 [68.4%] or engaging in other riverine activities. Most injuries [n=14 (73.7%] occurred from September through November, and most injured respondents [n=15 (78.9%] reported seeing stingrays at beaches. Severe pain and the appearance of ulcers in the later stages of envenomation were described by 18 (94.7% and 12 (63.2% participants, respectively. CONCLUSIONS Freshwater stingray injuries, which should be considered occupational injuries, are common in the study area, especially in places like beaches or in the lakes that form during the dry season, when stingrays are routinely observed. A significant proportion of respondents was unaware of the correct first aid measures and had insufficient resources to treat the complications of these injuries in the locality where they reside. Interactive activities involving local residents - such as lectures and the distribution of simple pamphlets providing information about stingray injuries - are needed.

Concomitant rupture of the subclavian vessels and the left main bronchus caused by blunt trauma is a serious condition. Moreover, the diagnosis of a tracheobronchial injury with rupture of the subclavian vessels can be difficult. This report describes the case of a 33-year-old man who suffered from blunt trauma that resulted in the rupture of the left subclavian artery and vein. The patient underwent an operation for vascular control. On postoperative day 3, the left main bronchus was found to be transected on a computed tomography scan and bronchoscopy. The transected bronchus was anastomosed in an end-to-end fashion. He recovered without any notable problems. Although the bronchial injury was not detected early, this case of concomitant rupture of the great vessels and the airway was successfully treated after applying extracorporeal membrane oxygenation.

Juvenile osteoarthritis as consequence of enchondral injuries.. Frostbite, Kashin-Beck disease, rat bites and other causes

2000-01-01

Purpose. To review the similarities of the radiographic changes in frostbite, the Asian disease of Kashin-Beck, and long term growth damage from injury such as rate bite. Materials and Methods. Radiographs and literature from subjects with these diagnoses were analyzed for the common features and differences. Included was an infant with hand changes 8 months after unwitnessed rat bites. Results. Each condition revealed findings consistent with the hypothesis of localized damage to sites of enchondral ossification, including at acrophyses - the growth plates that are not between epiphysis and metaphysis, but instead lie at the margins of growth centers, including carpal and tarsal bones, and the non-epiphyseal ends of small tubular bones. Discussion. The patterns observed support a final common pathway of damage in frostbite due to cold injury, Kashin-Beck disease (endemic in China) of unknown etiology, and damage from toxines associated, for example, with rat bite. In frostbite, the distribution is acral because of the site of exposure, while the distribution in Kashin-Beck is more diffuse and often less contiguous. In each condition, arthrotic sequelae may be expected in the natural course of follow-up. MRI may play a role in acute diagnosis that might modify the course of each disease. (orig.) [de

Road traffic accidents (RTAs) have been identified by public health organizations as being of major global concern. Traumatic brain injuries (TBIs) are among the most severe injuries and are in a large part caused by RTA. The objective of this article is to analyse the severity and outcome of TBI caused by RTA in different types of road users in five European countries. The demographic, severity and outcome measures of 683 individuals with RTA-related TBI from Austria, Slovakia, Bosnia, Croatia and Macedonia were analysed. Five types of road users (car drivers, car passengers, motorcyclists, bicyclists and pedestrians) were compared using univariate and multivariate statistical methods. Short-term outcome [intensive care unit (ICU) survival] and last available long-term outcome of patients were analysed. In our data set, 44% of TBI were traffic related. The median age of patients was 32.5 years, being the lowest (25 years) in car passengers. The most severe and extensive injuries were reported in pedestrians. Pedestrians had the lowest rate of ICU survival (60%) and favourable long-term outcome (46%). Drivers had the highest ICU survival (73%) and car passengers had the best long-term outcome (59% favourable). No differences in the outcome were found between countries with different economy levels. TBI are significantly associated with RTA and thus, tackling them together could be more effective. The population at highest risk of RTA-related TBI are young males (in our sample median age: 32.5 years). Pedestrians have the most severe TBI with the worst outcome. Both groups should be a priority for public health action.

Full Text Available Bilateral-hand amputation is extremely rare and double-hand replantation is even rarer. Only one case of successful double replantation at arm level has been reported from India. We present a case of double-hand replantation at proximal palmar level in a young adult executed in a small nursing home. The patient presented 5 h after injury with limbs preserved well in ice. There were difficulties in executing such an unusual case in a small nursing home set-up. The patient is performing his activities of daily living and basic functions independently. We share our experience of this double-hand replantation with special emphasis on problems encountered.

Ozone (O 3 )-related cardiorespiratory effects are a growing public health concern. Ground level O 3 can exacerbate pre-existing respiratory conditions; however, research regarding therapeutic interventions to reduce O 3 -induced lung injury is limited. In patients with chronic obstructive pulmonary disease, hypoxia-associated pulmonary hypertension (HPH) is a frequent comorbidity that is difficult to treat clinically, yet associated with increased mortality and frequency of exacerbations. In this study, we hypothesized that established HPH would confer vulnerability to acute O 3 pulmonary toxicity. Additionally, we tested whether improvement of pulmonary endothelial barrier integrity via rho-kinase inhibition could mitigate pulmonary inflammation and injury. To determine if O 3 exacerbated HPH, male C57BL/6 mice were subject to either 3 weeks continuous normoxia (20.9% O 2 ) or hypoxia (10.0% O 2 ), followed by a 4-h exposure to either 1 ppm O 3 or filtered air (FA). As an additional experimental intervention fasudil (20 mg/kg) was administered intraperitoneally prior to and after O 3 exposures. As expected, hypoxia significantly increased right ventricular pressure and hypertrophy. O 3 exposure in normoxic mice caused lung inflammation but not injury, as indicated by increased cellularity and edema in the lung. However, in hypoxic mice, O 3 exposure led to increased inflammation and edema, along with a profound increase in airway hyperresponsiveness to methacholine. Fasudil administration resulted in reduced O 3 -induced lung injury via the enhancement of pulmonary endothelial barrier integrity. These results indicate that increased pulmonary vascular pressure may enhance lung injury, inflammation and edema when exposed to pollutants, and that enhancement of pulmonary endothelial barrier integrity may alleviate such vulnerability. - Highlights: • Environmental exposures can exacerbate chronic obstructive pulmonary disease (COPD). • It is unknown if comorbid

Hand osteoarthritis is one of the most common forms of arthritis which impact millions of people worldwide. The disabling problem occurs when the protective cartilage on the boundaries of bones wear off over time. Currently, in order to identify hand osteoarthritis, special instruments namely X-ray scanning and MRI are used for the detection but it also has its limitations such as radiation exposure and can be quite costly. In this work, an optical metrology system based on digital fringe projection which comprises of an LCD projector, CCD camera and a personal computer has been developed to anticipate abnormal growth or deformation on the joints of the hand which are common symptoms of osteoarthritis. The main concept of this optical metrology system is to apply structured light as imaging source for surface change detection. The imaging source utilizes fringe patterns generated by C++ programming and is shifted by 3 phase shifts based on the 3 steps 2 shifts method. Phase wrapping technique and analysis were applied in order to detect the deformation of live subjects. The result has demonstrated a successful method of hand deformation detection based on the pixel tracking differences of a normal and deformed state.

Acute lung injury (ALI) is the leading cause of death in intensive care units. Extracellular histones have recently been recognized to be pivotal inflammatory mediators. Heparin and its derivatives can bind histones through electrostatic interaction. The purpose of this study was to investigate 1) the role of extracellular histones in the pathogenesis of ALI caused by acid aspiration and 2) whether N-acetyl-heparin (NAH) provides more protection than heparin against histones at the high dose. ALI was induced in mice via intratracheal instillation of hydrochloric acid (HCl). Lethality rate, blood gas, myeloperoxidase (MPO) activity, lung edema and pathological changes were used to evaluate the degree of ALI. Heparin/NAH was administered intraperitoneally, twice a day, for 3 days or until death. Acid aspiration caused an obvious increase in extracellular histones. A significant correlation existed between the concentration of HCl aspirated and the circulating histones. Heparin/NAH (10 mg/kg) improved the lethality rate, blood gas, MPO activity, lung edema and pathological score. At a dose of 20 mg/kg, NAH still provided protection, however heparin tended to aggravate the injury due to hemorrhagic complications. The specific interaction between heparin and histones was verified by the binding assay. In summary, high levels of extracellular histones can be pathogenic in ALI caused by acid aspiration. By neutralizing extracellular histones, heparin/NAH can offer similar protection at the moderate doses. At the high dose, NAH provides better protection than heparin.

In pedestrian-vehicle accidents, pedestrians typically suffer from secondary impact with the ground after the primary contact with vehicles. However, information about the fundamental mechanism of pedestrian head injury from ground impact remains minimal, thereby hindering further improvement in pedestrian safety. This study addresses this issue by using multi-body modeling and computation to investigate the influence of vehicle front-end shape on pedestrian safety. Accordingly, a simulation matrix is constructed to vary bonnet leading-edge height, bonnet length, bonnet angle, and windshield angle. Subsequently, a set of 315 pedestrian-vehicle crash simulations are conducted using the multi-body simulation software MADYMO. Three vehicle velocities, i.e., 20, 30, and 40km/h, are set as the scenarios. Results show that the top governing factor is bonnet leading-edge height. The posture and head injury at the instant of head ground impact vary dramatically with increasing height because of the significant rise of the body bending point and the movement of the collision point. The bonnet angle is the second dominant factor that affects head-ground injury, followed by bonnet length and windshield angle. The results may elucidate one of the critical barriers to understanding head injury caused by ground impact and provide a solid theoretical guideline for considering pedestrian safety in vehicle design.

In the absence of adequate premarketing efficacy and safety evaluations, adverse events from over-the-counter supplements are emerging as a public health concern. Specifically, bodybuilding products are being identified as a frequent cause of drug-induced liver injury. We present a case of a 20-year-old Hispanic male who presented with acute nausea and vomiting accompanied by severe right upper quadrant abdominal pain, shivering, and shortness of breath. Laboratory data pointed to mixed cholestatic and hepatocellular damage, and after exclusion of known alternate etiologies, the patient was diagnosed with acute drug-induced liver injury secondary to the use of "Friction," a bodybuilding supplement. Treatment with N-acetylcysteine (NAC) 20% oral solution was initiated empirically at a dose of 4000 mg [DOSAGE ERROR CORRECTED] (70 mg/kg) every 4 hours and was continued once the diagnosis was made. Within 48 hours of admission to our hospital, the patient began to show clinical resolution of right abdominal pain and tolerance to oral diet associated with a significant decline toward normal in his liver function tests and coagulopathy. The WHO-UMC causality assessment system suggested a "certain causality" between exposure to the supplement and the acute liver injury. In the event of suspected drug-induced liver injury, treatment with NAC should be considered given its favorable risk-benefit profile. © 2015 Pharmacotherapy Publications, Inc.

The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity caused by conventional medications as well as herbals and dietary supplements (HDS). To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The study took place among eight U.S. referral centers that are part of the DILIN. Consecutive patients with liver injury referred to a DILIN center were eligible. The final sample comprised 130 (15.5%) of all subjects enrolled (839) who were judged to have experienced liver injury caused by HDS. Hepatotoxicity caused by HDS was evaluated by expert opinion. Demographic and clinical characteristics and outcome assessments, including death and liver transplantation (LT), were ascertained. Cases were stratified and compared according to the type of agent implicated in liver injury; 45 had injury caused by bodybuilding HDS, 85 by nonbodybuilding HDS, and 709 by medications. Liver injury caused by HDS increased from 7% to 20% (P Bodybuilding HDS caused prolonged jaundice (median, 91 days) in young men, but did not result in any fatalities or LT. The remaining HDS cases presented as hepatocellular injury, predominantly in middle-aged women, and, more frequently, led to death or transplantation, compared to injury from medications (13% vs. 3%; P bodybuilding HDS or medications, as evidenced by differences in unfavorable outcomes (death and transplantation).

We describe a case of methaemoglobinaemia (MtHb) in a previously healthy 39-year-old gentleman who presented with a traumatic glass laceration to his right wrist that required emergency surgery to control bleeding and repair his ulnar artery. The MtHb was noted on blood gas analysis by the anaesthetist after the patient had a drop in arterial oxygen saturation under general anaesthetic. We initially suspected the lidocaine local anaesthetic injected proximal to his wound for pain control in the emergency department an hour preoperatively, but then discovered that the patient was a recreational user of 'poppers' and had in fact been using these drugs just before his injury and hospitalisation. The patient's condition stabilised overnight with conservative management. Given how commonly hand surgeons and other clinical staff use local anaesthetics, we reviewed the literature on this uncommon, but potentially fatal, complication, its causes and evidence-based management.

Hand surgery fellowship programs in the United States are predominately sponsored by departments or divisions of orthopaedic surgery or plastic surgery. This study compares the operative experiences of hand surgery fellows graduating from orthopaedic or plastic surgery hand surgery fellowships. Operative case logs of 3 cohorts of hand surgery fellows graduating during the academic years of 2012-2013, 2013-2014, and 2014-2015 were analyzed. The median case volumes were compared by specialty via Mann-Whitney U tests. An arbitrary 1,000% change between the 90th and 10th percentiles of fellows was used as a threshold to highlight case categories with substantial variability. In this study, 413 orthopaedic hand surgery fellows (87%) and 62 plastic surgery hand surgery fellows (13%) were included. Plastic surgery fellows reported more cases in the following categories: wound closure with graft; wound reconstruction with flap; vascular repair, reconstruction, replantation, or microvascular; closed treatment of fracture or dislocation; nerve injury; and congenital (p < 0.05). Orthopaedic surgery fellows reported more cases in the following categories: wound irrigation and debridement fasciotomy or wound preparation; hand reconstruction or releases; wrist reconstruction, releases, or arthrodesis; forearm, elbow, or shoulder reconstruction or releases; hand fractures, dislocation, or ligament injury; wrist fractures or dislocations; forearm and proximal fractures or dislocations; miscellaneous insertion or removal of devices; shoulder arthroscopy, elbow arthroscopy, and wrist arthroscopy; decompression of tendon sheath, synovectomy, or ganglions; nerve decompression; Dupuytren; and tumor or osteomyelitis (p < 0.05). Plastic surgery fellows reported substantial variability for 12 case categories (range, 1,024% to 2,880%). Orthopaedic surgery fellows reported substantial variability for 9 case categories (range, 1,110% to 9,700%). Orthopaedic and plastic hand surgery

To report the epidemiology, mechanism, anatomical location, distribution, and severity of open extensor tendon injuries in the digits, hand, and forearm as well as the frequency of associated injuries to surrounding bone and soft tissue. Retrospective chart review was conducted for patients who had operative repair of open digital extensor tendon injuries in all zones within an 11-year period. Data was grouped according to patient characteristics, zone of injury, mechanism of injury, and presence of associated injury. Statistical analysis was used to determine the presence of relevant associations. Eighty-six patients with 125 severed tendons and 105 injured digits were available for chart reviews. Patients were predominantly males (83%) with a mean age of 34.2 years and the dominant extremity was most often injured (60%). The thumb was the most commonly injured (25.7%), followed by middle finger (24.8), whereas small finger was least affected (10.5%). Sharp laceration was the most common mechanism of injury (60%), and most of these occurred at or proximal to the metacarpophalangeal joints. Most saw injuries occurred distal to the metacarpophalangeal joint. Zone V was the most commonly affected in the fingers (27%) while zone VT was the most commonly affected in the thumb (69%). Associated injuries to bone and soft tissue occurred in 46.7% of all injuries with saw and crush/avulsions being predictive of fractures and damage to the underlying joint capsule. The extensor mechanism is anatomically complex, and open injuries to the dorsum of the hand, wrist, and forearm, especially of crushing nature and those inflicted by saws, must be thoroughly evaluated. Associated injuries should be ruled out in order to customize surgical treatment and optimize outcome.

Full Text Available Background: There is no study available on the frequency, predisposing factors and outcome of needle stick injury (NSI in cytopathologists who perform fine needle aspiration (FNA. Aim: To know the frequency, circumstances and sequlae of NSI sustained by cytopathologists, assess their knowledge about risks of NSI and attitudes and practices towards use of standard precautions and post-injury wound care. Materials and Methods: Study design: cross sectional. Setting: Tertiary care teaching and non-teaching hospitals and private laboratories. Data collection method: Knowledge, attitude and practices survey using a questionnaire. Results: Majority (90.5% of the respondents have had NSI in their total career. In the previous year, more than half (71.4% had at least one NSI (mean 3.2. NSI was the most common in index finger of non-dominant hand (59.6% and occurred during step two of FNA procedure when the needle was being manipulated within the lump. The major predisposing factors were uncooperative patients (88.9%, small children (54%, deep masses (36.5%, hot humid climate (88.9%, heavy workload (76.2% and poor administrative arrangement (54%. The adherence to standard precautions was not optimal (74.6%. None of them reported NSI to the authorities, nor investigated source patient or themselves. 82.5% of the respondents were not aware of any formal exposure reporting system in their hospital. Conclusion: Cytopathologists frequently experience NSI while performing FNA. Frequency of injury is also related to patient characteristics and work site factors. Education and motivation for adhering to standard precautions and post-exposure prophylaxis are often lacking.

Background: In literature, the competitive sport of modern karate is almost always characterised as a combat sport involving injuries caused by impact effects and physical contact with opponents. There is a lack of data regarding the outcome after karate injuries, specifically with a view to the contact-free Kata karate. Methods: Performing a random test using a questionnaire, we collected data concerning regular medical treatment, prior surgeries of the locomotor system, and medical care. This study included 300 athletes from 65 countries (average age: 24.1 years; 176 male, 124 female) participating in the Karate World Cup 2014. Seven participants competed in both disciplines, 87 only in the Kata discipline, and 206 only in Kumite (the discipline involving physical contact with opponents). The statistical analysis was performed using a two-sided Chi-square test and the Fisher's exact test. Results : Recurrent medical treatment was most commonly required for the knee region (Kata 28.7 %, Kumite 26.7 %). In Kata the shoulder region came second (22.9 %), in Kumite the ankle region (21.8 %), followed by hand and foot in both groups. Medical treatment of the elbow area was more frequent in the Kata Group (p = 0.033), while in Kumite athletes' hand (p = 0.002) and foot injuries (p = 0.007) prevailed. Prior surgeries of athletes of both disciplines most commonly concerned the knee, followed by the ankle region in the Kata group and by the hand and head region in the Kumite group. Statistically significant differences between the two disciplines were found in head injuries (p = 0.004), which commonly do not occur in the Kata discipline. During the World Cup, 56.0 % of the athletes had no individual medical care and 24.6 % received no sports-related medical care in their home countries. Conclusion: Although the risk of injuries in Kumite Karate has been reduced by the introduction of gumshields, hand and foot protectors as well as a reform of

Pathophysiology and Treatment of Alien Hand Syndrome

2014-12-01

Full Text Available Background: Alien hand syndrome (AHS is a disorder of involuntary, yet purposeful, hand movements that may be accompanied by agnosia, aphasia, weakness, or sensory loss. We herein review the most reported cases, current understanding of the pathophysiology, and treatments.Methods: We performed a PubMed search in July of 2014 using the phrases “alien hand syndrome,” “alien hand syndrome pathophysiology,” “alien hand syndrome treatment,” and “anarchic hand syndrome.” The search yielded 141 papers (reviews, case reports, case series, and clinical studies, of which we reviewed 109. Non‐English reports without English abstracts were excluded.Results: Accumulating evidence indicates that there are three AHS variants: frontal, callosal, and posterior. Patients may demonstrate symptoms of multiple types; there is a lack of correlation between phenomenology and neuroimaging findings. Most pathologic and functional imaging studies suggest network disruption causing loss of inhibition as the likely cause. Successful interventions include botulinum toxin injections, clonazepam, visuospatial coaching techniques, distracting the affected hand, and cognitive behavioral therapy.Discussion: The available literature suggests that overlap between AHS subtypes is common. The evidence for effective treatments remains anecdotal, and, given the rarity of AHS, the possibility of performing randomized, placebo‐controlled trials seems unlikely. As with many other interventions for movement disorders, identifying the specific functional impairments caused by AHS may provide the best guidance towards individualized supportive care.

Hypoglycemia is induced by many causes, especially over-dose of insulin or oral hypoglycemic agents in diabetic subjects. In such a case, hyperinsulinemic hypoglycemia is usually observed. On the other hand, it is important to classify secondary hypoglycemia and hypoinsulinemic hypoglycemia. Liver injury-induced hypoglycemia is one of the causes of hypoinsulinemic hypoglycemia but rarely observed in clinical practice. Herein, we experienced similar 2 cases of non-diabetic hypoinsulinemic hypoglycemia. Both of them were elderly subjects with low body weight. Furthermore, it is likely that hypoinsulinemic hypoglycemia in both subjects was triggered by severe liver injury, at least in part, due to possible limited liver glycogen store. In elderly subjects with low body weight and/or malnutrition, metabolism in the liver is reduced and glycogen accumulation is decreased. Such alteration brings out acute and marked liver injury, which finally leads to the onset of severe hypoglycemia. It is known that not only liver injury but also multiple organ failure could be induced due to extreme emaciation in subjects. It is likely that in elderly subjects with low body weight and/or malnutrition, multiple organ failure including liver failure could be induced due to the similar reason. Therefore, we should be very careful of such subjects in order to avoid the development of multiple organ failure which leads to life-threatening situations. In conclusion, we should keep in mind the possibility of hypoinsulinemic hypoglycemia when we examine severe liver injury, especially in elderly or starving subjects with low body weight and limited liver glycogen stores. It is important to classify secondary hypoglycemia and hypoinsulinemic hypoglycemia.Liver injury-induced hypoglycemia is one of the causes of hypoinsulinemic hypoglycemia but rarely observed in everyday clinical practice.Herein, we reported similar 2 cases of hypoinsulinemic hypoglycemia without diabetes presumably triggered

Management of High-Voltage Burns of the Hand and Wrist with Negative Pressure Dressing

2017-12-01

Full Text Available Objective: Negative pressure dressing stimulates wound healing by promoting cellular proliferation and regeneration. It also removes interstitial edema and increases local blood flow, resulting in rapid growth of the granulation tissue. We used the dressing method in deep hand and wrist burns caused by high-voltage electrical current, which leads to progressive tissue necrosis, elevated compartment pressure, and deep tissue edema, to reveal if subatmospheric pressure could limit the zone of injury or ongoing tissue necrosis after electrical burn. Material and Methods: Six hands of five patients, who came in contact with high-voltage electrical wire carrying more than 1000 volts, are presented in this study. Hands and wrists were seriously injured and contracted. After the initial treatment involving fluid resuscitation, fasciotomy, carpal tunnel release, and debridement, a negative pressure dressing was applied to the wounds of hand, wrist, and forearm with 125 mm Hg continuous pressure, and maintained for 20 days. Results: When negative pressure dressing was stopped on the 20th day, significant granulation tissue developed over the hand and forearm wounds. However, wrist wounds needed more debridement and repeated dressings because of the presence of necrosis. Edema of the hands subsided significantly during the use of negative pressure dressing. Time to closure for hand and forearm wounds decreased considerably. Moreover, in one wrist, spontaneous closure was achieved at about one month. All hands except one treated with negative pressure dressing could be saved from amputation; however, significant tissue loss developed, needing complex reconstruction procedures. One hand was amputated because of the permanent loss of blood perfusion. Conclusion: The management of high-voltage burns of hand and wrist with subatmospheric pressure appears to be capable of reducing hand edema and accelerating closure of the wounds. It seems that negative
