Outcome and patients' satisfaction after functional treatment of acute lateral ankle injuries at emergency departments versus family doctor offices

BACKGROUND: In some Western countries, more and more patients seek initial treatment even for minor injuries at emergency units of hospitals. The initial evaluation and treatment as well as aftercare of these patients require large amounts of personnel and logistical resources, which are limited and costly, especially if compared to treatment by a general practitioner. In this study, we investigated whether outsourcing from our level 1 trauma center to a general practitioner has an influence on patient satisfaction and compliance. METHODS: This prospective, randomized study, included n = 100 patients who suffered from a lateral ankle ligament injury grade I-II (16, 17). After radiological exclusion of osseous lesions, the patients received early functional treatment and were shown physical therapy exercises to be done at home, without immobilization or the use of stabilizing ortheses. The patients were randomly assigned into two groups of 50 patients each: Group A (ER): Follow-up and final examination in the hospital's emergency unit. Group B (GP): Follow-up by general practitioner, final examination at hospital's emergency unit. The patients were surveyed regarding their satisfaction with the treatment and outcome of the treatment. RESULTS: Female and male patients were equally represented in both groups. The age of the patients ranged from 16 - 64 years, with a mean age of 34 years (ER) and 35 years (GP). 98% (n = 98) of all patients were satisfied with their treatment, and 93% (n = 93) were satisfied with the outcome. For these parameters no significant difference between the two groups could be noted (p = 0.7406 and 0.7631 respectively). 39% of all patients acquired stabilizing ortheses like ankle braces (Aircast, Malleoloc etc.) on their own initiative. There was a not significant tendency for more self-acquired ortheses in the group treated by general practicioners (p = 0,2669). CONCLUSION: Patients who first present at the ER with a lateral ankle ligament injury grade I-II can be referred to a general practitioner for follow-up treatment without affecting patient satisfaction regarding treatment and treatment outcome.

Gunshot injuries detected by post-mortem multislice computed tomography (MSCT): a feasibility study

Modern cross-sectional imaging techniques are being increasingly implemented in forensic pathology. These methods may serve as an adjuvant to classic forensic autopsies or even replace them altogether in the future. In order to assess the practicability of such a method, namely post-mortem multislice computed tomography (MSCT) in fatal gunshot injuries, 22 corpses underwent such an examination prior to forensic autopsy. The cardinal questions of the location of entrance and exit wounds, the detection of bullets and bullet fragments in the body, the bullet course, inflicted injuries and cause of death were addressed at MSCT and autopsy. The results of the two techniques revealed that post-mortem MSCT can answer these questions reliably and is therefore a useful tool in the assessment of such injuries.

Vacuum-assisted closure therapy increases local interleukin-8 and vascular endothelial growth factor levels in traumatic wounds

BACKGROUND: Clinical observations are suggesting accelerated granulation tissue formation in traumatic wounds treated with vacuum-assisted closure (VAC). Aim of this study was to determine the impact of VAC therapy versus alternative Epigard application on local inflammation and neovascularization in traumatic soft tissue wounds. METHODS: Thirty-two patients with traumatic wounds requiring temporary coverage (VAC n = 16; Epigard n = 16) were included. At each change of dressing, samples of wound fluid and serum were collected (n = 80). The cytokines interleukin (IL)-6, IL-8, vascular endothelial growth factor (VEGF), and fibroblast growth factor-2 were measured by ELISA. Wound biopsies were examined histologically for inflammatory cells and degree of neovascularization present. RESULTS: All cytokines were found to be elevated in wound fluids during both VAC and Epigard treatment, whereas serum concentrations were negligible or not detectable. In wound fluids, significantly higher IL-8 (p < 0.001) and VEGF (p < 0.05) levels were detected during VAC therapy. Furthermore, histologic examination revealed increased neovascularization (p < 0.05) illustrated by CD31 and von Willebrand factor immunohistochemistry in wound biopsies of VAC treatment. In addition, there was an accumulation of neutrophils as well as an augmented expression of VEGF (p < 0.005) in VAC wound biopsies. CONCLUSION: This study suggests that VAC therapy of traumatic wounds leads to increased local IL-8 and VEGF concentrations, which may trigger accumulation of neutrophils and angiogenesis and thus, accelerate neovascularization.

Anterior Cruciate Ligament Injuries in Children and Adolescents: A Review of the Recent Literature

In contrast to the treatment of avulsion lesions of the anterior cruciate ligament (ACL) the management of intrasubstance ACL tears in the skeletally immature patient remains controversial. Prospective studies could show that conservative treatment results in severe instability with concomitant intraarticular damage and poor function of the knee. Reconstruction of a torn ACL always carries the risk of damaging the open growth plates; with consecutively affecting the longitudinal or axial growth of the lower extremity either on the femoral or the tibial side. Thus, several surgical procedures are available to prevent adverse events mentioned above. The purpose of this study is to review the recent literature regarding the treatment algorithm for ACL injuries in skeletally immature patients. This review will (1) investigate the indications for ACL surgery in children; (2) determine if a surgical procedure is clinically superior in skeletally immature patients; and (3) correlate the adverse events with the surgical technique.

First results on the mandatory notification of dog bite injuries in Switzerland: a questionnaire survey among physicians and veterinarians

In order to expedite targeted interventions, mandatory notification of treated dog bite injuries for Swiss physicians and veterinarians was implemented in 2006. Since the number of notified cases was much lower than expected, the validity of the annually produced statistics with respect to the real situation in Switzerland was discussed controversially. In this study a questionnaire survey among physicians and veterinarians was carried out to evaluate the amount of and reasons for non-compliance with the mandatory notification. 81 % of the physicians and 97 % of the veterinarians reported the treatment of dog bite injuries in the year 2009. Among those, 60 % of the physicians and 41 % of the veterinarians indicated notification of less than 50 % of the treated cases. Our results indicate that the most relevant cases for targeted interventions seem to be notified, but that the statistical analyses have to be interpreted carefully.

Acetabulum injuries in infancy and childhood

In this article, the anatomical and morphological features of the acetabulum in infancy and childhood are presented. The pathology and treatment of older children and adolescents is deliberately not covered, because the fracture morphology and treatment of patients aged 13 to 15 years is based on the criteria of adult medicine. Especially in the younger child, the anatomical differences are of particular importance. The younger the child is, the more difficult the diagnosis. Therefore today, MRI examinations should be generous used, even if anesthesia is necessary. If the injured child is hemodynamic stable, anesthesia can be electively used for a more complex diagnosis. Acetabular fractures are particularly problematic in infancy because even with optimal treatment and perfect reduction growth disturbances can occur. These manifest as so-called secondary dysplasia. During treatment, care should be taken to ensure that a surgical team having experience with the infant and juvenile skeleton is available and that appropriate implants are available.

Dog Bite Injuries: Primary and Secondary Emergency Department Presentations-A Retrospective Cohort Study

Dog bites in humans are a complex problem, embracing both public health and animal welfare. The primary aim of this study is to examine primary and secondary presentations related to dog bite injuries in adults. Methods. We retrospectively assessed all adult patients admitted with a dog bite injury to the Emergency Department of Bern University Hospital. Results. A total of 431 patients were eligible for the study. Forty-nine (11.4%) of all patients were admitted with secondary presentations. Bites to the hands were most common (177, 41.1%). All patients (47, 100%) with secondary presentations were admitted because of signs of infection. The median time since the dog bite was 3.8 days (SD 3.9, range 1–21). Thirty-one patients had already been treated with antibiotic; coamoxicillin was the most common primary antibiotic therapy (27/47 patients, 57.4%). Patients with injuries to the hand were at increased risk of secondary presentations (OR 2.08, 95% CI 1.21–3.55, < 0.006). Conclusion. Dog bite injuries to the hands are a major problem. They often lead to infectious complications. Immediate antibiotic therapy should carefully be evaluated for each patient.

Injuries in agriculture-injury severity and mortality

PRINCIPALS Accidents in agriculture are a problem of global importance. The hazards of working in agriculture are manifold (machines, animals, heights). We therefore assessed injury severity and mortality from accidents in farming. METHODS We retrospectively analysed all farming accidents treated over a 12-year period in the emergency department (ED) of our level I trauma centre. RESULTS Out of 815 patients 96.3% were male and 3.7% female (p <0.0001). A total of 70 patients (8.6%, 70/815) were severely injured. Patients with injuries to the chest were most likely to suffer from severe injuries (odds ratio [OR] 9.45, 95% confidence interval [CI] 5.59-16.00, p <0.0001), followed by patients with injuries to the abdomen (OR 7.06, 95% CI 3.22-15.43, p <0.0001) and patients with injuries to the head (OR 5.03, 95% CI 2.99-8.66, p <0.0001). Hospitalisation was associated with machine- and fall-related injuries (OR 22.39, 95% CI 1.95-4.14, p <0.0001 and OR 2.84 95% CI 1.68-3.41 p <0.001, respectively). Patients suffering from a fall and patients with severe injury were more likely to die than others (OR 3.32, 95% CI 1.07-10.29, p <0.037 and OR 9.17, 95% CI 6.20-13.56, p <0.0001, respectively). Fall height correlated positively with the injury severity score , hospitalisation and mortality (all p <0.0001). CONCLUSION Injuries in agriculture are accompanied by substantial morbidity and mortality, and range from minor injuries to severe multiple injuries. Additional prospective studies should be conducted on injury severity, long-term disability and mortality.

Outcomes of truncal vascular injuries in children.

BACKGROUND: Pediatric truncal vascular injuries occur infrequently and have a reported mortality rate of 30% to 50%. This report examines the demographics, mechanisms of injury, associated trauma, and outcome of patients presenting for the past 10 years at a single institution with truncal vascular injuries. METHODS: A retrospective review (1997-2006) of a pediatric trauma registry at a single institution was undertaken. RESULTS: Seventy-five truncal vascular injuries occurred in 57 patients (age, 12 +/- 3 years); the injury mechanisms were penetrating in 37%. Concomitant injuries occurred with 76%, 62%, and 43% of abdominal, thoracic, and neck vascular injuries, respectively. Nonvascular complications occurred more frequently in patients with abdominal vascular injuries who were hemodynamically unstable on presentation. All patients with thoracic vascular injuries presenting with hemodynamic instability died. In patients with neck vascular injuries, 1 of 2 patients who were hemodynamically unstable died, compared to 1 of 12 patients who died in those who presented hemodynamically stable. Overall survival was 75%. CONCLUSIONS: Survival and complications of pediatric truncal vascular injury are related to hemodynamic status at the time of presentation. Associated injuries are higher with trauma involving the abdomen.

Frederiksenia canicola gen. nov., sp. nov. isolated from dogs and human dog-bite wounds.

Polyphasic analysis was done on 24 strains of Bisgaard taxon 16 from five European countries and mainly isolated from dogs and human dog-bite wounds. The isolates represented a phenotypically and genetically homogenous group within the family Pasteurellaceae. Their phenotypic profile was similar to members of the genus Pasteurella. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry clearly identified taxon 16 and separated it from all other genera of Pasteurellaceae showing a characteristic peak combination. Taxon 16 can be further separated and identified by a RecN protein signature sequence detectable by a specific PCR. In all phylogenetic analyses based on 16S rRNA, rpoB, infB and recN genes, taxon 16 formed a monophyletic branch with intraspecies sequence similarity of at least 99.1, 90.8, 96.8 and 97.2 %, respectively. Taxon 16 showed closest genetic relationship with Bibersteinia trehalosi as to the 16S rRNA gene (95.9 %), the rpoB (89.8 %) and the recN (74.4 %), and with Actinobacillus lignieresii for infB (84.9 %). Predicted genome similarity values based on the recN gene sequences between taxon 16 isolates and the type strains of known genera of Pasteurellaceae were below the genus level. Major whole cell fatty acids for the strain HPA 21(T) are C14:0, C16:0, C18:0 and C16:1 ω7c/C15:0 iso 2OH. Major respiratory quinones are menaquinone-8, ubiquinone-8 and demethylmenaquinone-8. We propose to classify these organisms as a novel genus and species within the family of Pasteurellaceae named Frederiksenia canicola gen. nov., sp. nov. The type strain is HPA 21(T) (= CCUG 62410(T) = DSM 25797(T)).

Return to Work after Traumatic Hand Injuries: Medical, Personal and Work-related Factors

PURPOSE This study aimed to examine the work-related impact of open hand injuries, specifically, the amount of lost work days subsequent to the injury and factors associated with work-related rehabilitation. PATIENTS AND METHODS We retrospectivley included consecutive patients with acute hand injuries who were operated between 2008 and 2009 in the Division of Hand Surgery (n=435) at the Department of Orthopaedic, Plastic and Hand Surgery. Information was obtained from the medical records and via a self-reported questionnaire sent out in 2011. Patients younger than 18 or older than 65 years, as well as the unemployed were excluded from the study. Descriptive group analysis was used to establish statistical relationships between time off work (TOW) and possible influencing variables. Multiple linear regression was applied to analyse the impact of injury, personal and/or work-related factors on TOW. RESULTS The sample included 290 patients with a mean age of 38.9 (SD 13.2) years of whom 98.6% returned to work after a median absence of 45.5 days. Univariate analysis demonstrated an association of length of absence from work with socio-demographic, clinical and work-related factors. Multiple regression analysis indicated that the location of injury, the number of injured regions, the need for secondary surgery, age, and the type of occupation were independently associated with TOW. CONCLUSION Most factors associated with TOW after traumatic hand injuries could not be influenced. Possible interventions should probably target improved injury prevention, optimal clinical treatment and rehabilitation starting early after injury. Whether improvements in communication and enhancement of cooperation between the treatment teams, the workplace and the insurance carrier may support a staged and earlier return to work remains to be investigated.
