Epidemiology of work-related hand and wrist injuries in a referral center: A descriptive study

BACKGROUND Occupational hand and wrist injuries(OHWIs)account for 25%of work-related accidents in low-and middle-income countries.In Colombia,more than 500000 occupational accidents occurred in 2021,and although the rate declined to less than 5%in 2020 and 2021,at least one in four accidents involved a hand or wrist injury.AIM To describe the OHWIs in workers seen at the emergency room at a second-level hospital in Colombia.METHODS An observational study was performed using data from workers who experienced OHWIs and attended a second-level hospital,between June,2020 and May,2021.The overall frequency of OHWIs,as well as their distribution by sociodemo-graphic,clinical,and occupational variables,are described.Furthermore,association patterns between sex,anatomical area(fingers,hand,wrist),and type of job were analyzed by correspondence analysis(CA).RESULTS There were 2.101 workers treated for occupational accidents,423(20.3%)were cases of OHWIs,which mainly affected men(93.9%)with a median age of 31 years and who worked mainly in mining(75.9%).OHWIs were more common in the right upper extremity(55.3%)and comprised different types of injuries,such as contusion(42.1%),laceration(27.9%),fracture(18.7%),and crush injury(15.6%).They primarily affected the phalanges(95.2%),especially those of the first finger(25.7%).The CAs showed associations between the injured anatomical area and the worker’s job that differed in men and women(explained variance>90%).CONCLUSION One out of five workers who suffered occupational accidents in Cundinamarca,Columbia had an OHWI,affecting mainly males employed in mining.This occupational profile is likely to lead to prolonged rehabilitation,and permanent functional limitations.Our results might be useful for adjusting preventive measures in cluster risk groups.

Epidemiology of isolated hand injuries in the United Arab Emirates

AIM To provide suggestions for hand injury prevention by study the demography and risk factors of casualties suffering from isolated hand injuries.METHODS All trauma patients with isolated hand injuries who were admitted to Al Ain Hospital for more than 24 h during a period of 3 years were studied. Patient demographics,location, mechanism/time of injury, and length of hospital stay were all analyzed.RESULTS Two hundred and ten patients were studied. Their mean age was 29.7 years. Males constituted 92%. Sixty-five point one percent of all cases were from the Indian subcontinent. The workplace was the most common location of injury(67.1%), followed by the home(17.1%)and road(6.2%). Machinery caused 36.2% of all injuries,followed by heavy object(20.5%) and fall(11%). Cases injured at home were young(P < 0.0001) with an associated higher incidence of females(P < 0.0001).CONCLUSION Male workers in Al Ain city are at greater risk of sustaining hand injuries, predominantly from machinery. Safety education, personal protection, and the enforcement of safety standards are essential to the prevention and avoidance of hand injury.

Epidemiology and Sequelae of Workplace Hand Injuries at a Tertiary Trauma Care Centre

Aims & Objectives: To study the epidemiology of workplace hand injuries, to understand relation between mode of injury and prognosis, to investigate into the possible contributing factors and to study the Socio-economic impact. Design of Study: For the prospective study there were 2 sources of data: 1) Proforma which was filled by the hand surgeon and 2) A questionnaire that was filled up by safety officer. For the retrospective study case, sheets were retrieved from the Medical Records section and a telephonic or personal interview was carried out by a single interviewer. Setting: Department of Plastic and Reconstructive Surgery, Parvathy Hospital, Chennai, India. Patients: A total of 419 industrial injury patients treated from January 2008 to January 2013 were included in the study. Further follow-up regarding return to work and residual disability continues. Main Outcome Measures: Personal details (Age, Gender, Handedness, Work experience, Income). Type of injury, mode of injury, day and time of injury, treatment given, disability and number of working days lost were measured. Results: Those workers who were experienced less than 6 months had more workplace injuries and the commonest contributing factor was co-workers carelessness followed by long working hours and faulty machinery. Maximum injuries occurred on Monday and morning shift. Conclusions: Constant supervision of trainees for 2 years, shorter working hours with regular breaks, regular health checkups for personnel, regular servicing of machines can prevent occurrence of hand injuries. Corrective surgery within 6 hours, systematic and protocol based physiotherapy and rehabilitation can reduce the economic loss and disability arising out of work place injuries.

A Workable Solution for Reducing the Large Number of Vehicle and Pedestrian Accidents Occurring on a Yellow Light

Traffic intersections are incredibly dangerous for drivers and pedestrians. Statistics from both Canada and the U.S. show a high number of fatalities and serious injuries related to crashes at intersections. In Canada, during 2019, the National Collision Database shows that 28% of traffic fatalities and 42% of serious injuries occurred at intersections. Likewise, the U.S. National Highway Traffic Administration (NHTSA) found that about 40% of the estimated 5,811,000 accidents in the U.S. during the year studied were intersection-related crashes. In fact, a major survey by the car insurance industry found that nearly 85% of drivers could not identify the correct action to take when approaching a yellow traffic light at an intersection. One major reason for these accidents is the “yellow light dilemma,” the ambiguous situation where a driver should stop or proceed forward when unexpectedly faced with a yellow light. This situation is even further exacerbated by the tendency of aggressive drivers to inappropriately speed up on the yellow just to get through the traffic light. A survey of Canadian drivers conducted by the Traffic Injury Research Foundation found that 9% of drivers admitted to speeding up to get through a traffic light. Another reason for these accidents is the increased danger of making a left-hand turn on yellow. According to the National Highway Traffic Safety Association (NHTSA), left turns occur in approximately 22.2% of collisions—as opposed to just 1.2% for right turns. Moreover, a study by CNN found left turns are three times as likely to kill pedestrians than right turns. The reason left turns are so much more likely to cause an accident is because they take a driver against traffic and in the path of oncoming cars. Additionally, most of these left turns occur at the driver’s discretion—as opposed to the distressingly brief left-hand arrow at busy intersections. Drive Safe Now proposes a workable solution for reducing the number of accidents occurring during a yellow light at intersections. We believe this fairly simple solution will save lives, prevent injuries, reduce damage to public and private property, and decrease insurance costs.

Blood-letting punctures at twelve Jing-Well points of the hand can treat cerebral ischemia in a similar manner to mannitol

A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method. Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand, and/or by injecting mannitol into the caudal vein twice daily. Brain tissue was collected at 24, 48 and 72 hours after modeling, and blood was collected through the retinal vein before Evans blue was injected, approximately 1 hour prior to harvesting of brain tissue. Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats. Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees. There was no significant difference between single treatment and combined treatment. Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion, and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection.

The risk of wound infection after simple hand laceration

BACKGROUND: This prospective observational study aimed to determine the infection rate of simple hand laceration(SHL), and to compare infection rates between patients who were prescribed antibiotics and those who were not.METHODS: The study was performed at two urban hospitals enrolling 125 emergency department(ED) patients with SHL. Exclusion criteria included patients with lacerations for more than 12 hours, immunocompromized patients, patients given antibiotics, and patients with gross contamination, bites or crush injuries. Wound infection was defined as clinical infection at a follow-up visit(10–14 days) or wound was treated with antibiotics. Patient satisfaction was also measured using a visual analogue scale 1–10, asking the patients about wound appearance. Demographic data and wound characteristics were compared between the infected and non-infected wounds. The infection rates were also compared between patients who received prophylactic antibiotics and those who did not. The results were presented with medians and quartiles or percentages with 95% confidence intervals(CI).RESULTS: In the 125 patients with SHL [median age: 28(18, 43); range: 1–102 years old; 36% female], 44(35%, 95% CI: 27%–44%) were given antibiotics in the ED. Wound infection was reported in 6 patients(4.8%, 95% CI: 2%–10%). Age, gender, history of diabetes and wound closure were not associated with wound infection(P>0.05). The infection rate was not significantly different between patients with or without antibiotic prophylaxis [7%(3/44), 95% CI: 2%–10% vs. 4%(3/81), 95% CI: 1%–11%, P=0.66]. Patient's satisfaction with appearance ofinfected and non-infected wounds were significantly different [7.5(6, 8) vs. 9(8, 10), P=0.01].CONCLUSION: Approximately 5% of simple hand lacerations become infected. Age, gender, diabetes, prophylactic antibiotics and closure technique do not affect the risk ofinfection.

Bilateral Pedicled Superficial Epigastric Flap in the Management of Circumferential Combined Degloving and Full Thickness Burn Hand Injury—A Case Report

We report a case of combined hand trauma in the form of circumferential degloving injury of the hand with full thickness friction burns of the hand, forearm and the distal part of the upper arm. On exploration the hand was found avascular with loss of vital structures and full thickness burns. As a salvage procedure the hand was embedded in the subcutaneous tissue of the abdomen for 4 weeks and after that elevated as an inferiorly based flap on the bilateral superficial inferior epigastric arteries. Two weeks later the hand was freed by division of the base of the flap bilaterally. The details and description of the injury, the procedure and the outcome are discussed.

Effects of erigeron breviscapus (Vant.) Hand-Mazz pretreatment on pathology and oxyradical level following spinal cord ischemia-reperfusion injury in rabbits

Objective To investigate the effects of erigeron breviscapus (Vant.) Hand-Mazz (erigeron breviscapus) pretreatment on pathology and oxyradical level in the spinal cord after ischemia-reperfusion (I/R) injury in rabbits. Methods A total of 40 New Zealand white rabbits were randomly divided into three groups: sham-operation group with 10 rabbits treated with only abdominal aorta exposure without occlusion,control group with 15 rabbits that underwent ischemia for 50 minutes and treated with matched saline,and experimental group with 15 rabbits that underwent ischemia for 50 minutes and treated with erigeron breviscapus (9mg/kg) injection before ischemia. Malondialdehyde (MDA) level and superoxide dismutase (SOD) activity in the spinal cord were examined at 6 and 24 hours after I/R,respectively. The morphological changes and the number of the spinal cord anterior horn motor neurons were observed and counted under the light microscope and electron microscope,respectively. Results The level of MDA was markedly decreased and SOD activity was increased in the experimental group compared with those in the control group (P<0.01). Compared with that in the control group,the number of motor neurons in the experimental group significantly increased at 24h after I/R (P<0.01) and the morphous of the motor neurons improved. Conclusion Erigeron breviscapus can reduce oxyradical production and the apoptosis of nerve cells,and protect nerve tissue structure and function after spinal cord I/R.

Supplementary motor area deactivation impacts the recovery of hand function from severe peripheral nerve injury

Although some patients have successful peripheral nerve regeneration,a poor recovery of hand function often occurs after peripheral nerve injury.It is believed that the capability of brain plasticity is crucial for the recovery of hand function.The supplementary motor area may play a key role in brain remodeling after peripheral nerve injury.In this study,we explored the activation mode of the supplementary motor area during a motor imagery task.We investigated the plasticity of the central nervous system after brachial plexus injury,using the motor imagery task.Results from functional magnetic resonance imaging showed that after brachial plexus injury,the motor imagery task for the affected limbs of the patients triggered no obvious activation of bilateral supplementary motor areas.This result indicates that it is difficult to excite the supplementary motor areas of brachial plexus injury patients during a motor imagery task,thereby impacting brain remodeling.Deactivation of the supplementary motor area is likely to be a serious problem for brachial plexus injury patients in terms of preparing,initiating and executing certain movements,which may be partly responsible for the unsatisfactory clinical recovery of hand function.

Three Reverse Adipofascial Cross Finger Flaps Used for Coverage of Raw Areas on Two Fingers of a Patient with Blast Injury of the Hand—Case Report

We report a case of blast injury to the left hand which resulted in fractures of the fingers with exposure of bones and joints of the phalanges. We used three reverse adipofascial cross finger flaps raised at the same time from 2 fingers to reconstruct adjacent fingers of the patient. The patient recovered well postoperatively and had good range of movement of the fingers. This avoided the complications of the use of regional or distal flaps. To our knowledge, this is the first case reported in which three reverse adipofascial cross fingers flaps are raised at the same time, two of them from an injured finger, to cover three raw areas on two fingers of a patient.

FMRI and EEG Reactions to Hand Motor Tasks in Patients with Mild Traumatic Brain Injury: Left-Hemispheric Sensitivity to Trauma

Background: Mild traumatic brain injury (mTBI) is one of the most common forms of cerebral pathology in young people and disorders involve dysfunctions in cognitive and motor spheres. We would like to examine the structural and functional alterations of the brain in patients with mTBI while performing hand movements. Methods: Twenty healthy right-handed subjects (age 25.1 ± 3.9) and 10 patients (age 27.9 ± 7.3) with mTBI without hemiparesis participated in the study using functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). FMRI and EEG reactions were analysed during right- and left-hand movements. Results: It was shown that fMRI reactive changes have a larger inter-individual variability of activation during left-hand movements in comparison with right-hand ones in healthy subjects. The TBI patients demonstrated an increase of a diffuse component of fMRI reactive changes compared to healthy people. A greater number of the brain structures was involved, mainly at the subcortical level, mostly in the left hemisphere during right-hand movement. EEG study demonstrated coherence changes for the slow (delta) frequency bands in the left hemisphere, while performing both hand movements. In healthy persons, EEG coherence changes were observed in the fast (alhpa2) frequency band predominantly in contralateral hemispheres, while performing hand movements. Conclusion: So, fMRI and EEG studies revealed the most expressed pathological reactive changes in the left hemisphere and the brain cortical structures during right-hand movements in patients after mTBI. These data allowed us to propose that the younger brain structures were the most sensitive to mTBI.
