Karate kick-induced myocardial contusion.

Myocardial contusion should be suspected in a selected patient group with blunt thoracic trauma, who have elevated troponin, ECG changes and/or haemodynamical instability. Echocardiography is useful for direct visualisation of possible complications. In stable conditions, MRI allows for good visualisation of the heart and can confirm a suspected myocardial contusion as well as demonstrate the extent of myocardial damage. Based on the present literature, the authors developed a diagram for the diagnostic approach of a patient with suspected myocardial contusion.

Fall-related ocular trauma in patients over 90 years in tertiary ophthalmic center in Germany: 90-TOSG Report 1.

PURPOSE: To investigate the clinical characteristics of fall-related ocular trauma in patients over 90 years of age. METHODS: Retrospective, medical record reviews. Patients over the age of 90 years treated in a tertiary center with fall-related ocular trauma were included in the study. RESULTS: Fifty consecutive patients (fifty eyes) were analyzed. The mean age was 93.6 ± 1.8 years and 41 patients (82%) were female. The most common site of the injuries was orbital fracture (18 patients, 36%), accompanied with open globe rupture (OGR) in three patients, and globe contusion in two patients. Seventeen patients (34%) presented with OGR. Ocular trauma score in those patients was category 1 in 10 patients (58.8%) and category 2 in the others. Conjunctival hemorrhage and/or periocular contusion was seen in 14 patients (28%) and globe contusion in six patients (12%). At the presentation, the mean best corrected visual acuity (BCVA) was 2.82 ± 0.24 logMAR in patients with OGR and 1.98 ± 0.81 logMAR in six patients with globe contusion. Three of the patients with OGR had a final vision of 20/200 or better whereas the remaining patients had hand movements or less. The most common risk factors were female gender (82%) and use of antihypertensive drugs (46%). CONCLUSION: Patients with OGR had a poor visual outcome despite the early treatment. It is important to raise public awareness about of the poor prognosis of ocular injuries due to falls in the elderly population in order to establish preventive measures.

Posterolateral tibial plateau bone bruises in anterior cruciate ligament (ACL) injuries and its association with lateral meniscal injuries.

INTRODUCTION: This study examined the prevalence of posterolateral tibial bone bruising in isolated anterior cruciate ligament (ACL) injuries, prevalence of meniscal injuries in ACL injuries, as well as the association between posterolateral tibial bone bruising and lateral meniscal tears among those with ACL injury undergoing Primary ACL Reconstruction. MATERIALS AND METHODS: Retrospective data on 130 patients who underwent primary ACL reconstructions was analysed. Their preoperative magnetic resonance images (MRI) were reviewed for the presence of posterolateral tibial bone bruise. The presence of meniscal injuries was recorded based on the arthroscopic findings from the operative records. RESULTS: 95 patients were recruited into the study. The prevalence of posterolateral bone bruise in this study was 41%. There was a statistically significant difference when comparing the prevalence of bone bruising to the time of injury to MRI (p<0.001). The prevalence of an injury to at least one meniscus at the time of ACLR surgery was 83.2%. The prevalence of lateral meniscus injuries in patients with bone bruise was found to be 53.9%. The crude odds ratio of a patient having a lateral meniscal tear in the presence of bone bruising was 1.56 (0.68, 3.54). This figure was even higher when it was adjusted for time to MRI and was 2.06 (0.77, 5.46). CONCLUSION: Prevalence of posterolateral tibial bone bruising in our study was 41%, and the prevalence of meniscal injury to either meniscus at the point of surgery was 83.2%, out of which the lateral meniscus tears were identified during ACLR surgery in 47.3% of the patients. We found there was no association between posterolateral tibial bone bruising to sex, age and mode of injury, but was sensitive to the interval between time of injury and MRI. The overall prevalence of lateral meniscal tears was higher in patients with posterolateral bone bruising but was not statistically significant with a P value of 0.31; however, the Crude odd ratio was 1.56 (0.68, 3.54) and was higher when adjusted to time of injury to MRI 2.06 (0.77, 5.46). We suggest for MRI to be done as soon as possible after injury in regard to bone bruising identification. We should be vigilant to look for lateral meniscal tears and anticipate for its repair in ACL injuries, especially so when we identify posterolateral tibial bruising on the preoperative MRI.

[Severe contusion of the eyeball as a risk factor for the development of proliferative vitreoretinopathy]. / Kontuziya glaznogo yabloka tyazheloi stepeni kak faktor riska razvitiya proliferativnoi vitreoretinopatii.

The article is devoted to the problem of proliferative vitreoretinopathy (PVR) developing after severe contusions of the eyeball. Some experts doubt the possibility of developing such a severe complication after a closed eye injury, however, the accumulated literature data and research by scientists demonstrate a high probability of developing PVR in such cases, which could lead to adverse outcomes. The article presents the views of different authors and systematizes information about the frequency and the risk factors of developing PVR after different types of closed eye injury. The main purpose of this review is to demonstrate a high probability of developing PVR after a closed eye injury, which should alert specialists at the first stages of treatment in such patients and stimulate timely prevention and treatment of this complication.

Safety of infraorbital hyaluronic acid injections: Outcomes of a meta-analysis on prospective clinical trials.

BACKGROUND: Hollowing of the infraorbital region represents a common concern among aesthetic patients. In the past decade, an increasing number of patients have resorted to noninvasive aesthetic procedures to treat these concerns. The objective of this study was to evaluate the safety profile of infraorbital hyaluronic acid injections for aesthetic rejuvenation. METHODS: Through a systematic review and meta-analysis of prospective clinical trials, investigators sought to answer the research question "Does the use of needle versus cannula during infraorbital HA injections result in the same incidence rate of adverse events?" The primary outcomes of interest were the incidence rates of ecchymosis and edema in subject groups treated with a needle or cannula. RESULTS: Subjects treated with needles had a statistically significant greater incidence rate of ecchymosis, compared to those treated with cannula. Conversely, subjects treated with cannula had a statistically significant greater incidence rate of edema, compared to those treated with needles. CONCLUSIONS: The incidence rates of adverse events following the administration of hyaluronic acid injections in the infraorbital region vary depending on whether a needle or cannula is used; with needles being associated with a greater risk of ecchymosis and cannulas being associated with a greater risk of edema. These findings should be discussed with patients prior to treatment consultation. Finally, as with most techniques, it is usually prudent to develop expertise with one technique before using a second, especially in cases where both approaches can be used and have different adverse event profiles.

Survey of practices for documenting evidence of bruises from physical abuse during child protection proceedings.

Accurate recording of forensically important information on bruises is vital in child protection proceedings (Royal College of Paediatrics and Child Health (RCPCH)). An online survey was distributed to the RCPCH child protection committees to assess compliance with guidance. 56 individuals were contacted by email, 47 (84%) completed the survey. Results showed that the paediatricians always or usually record size (n=41; 87%), site (n=45; 96%), shape (n=32; 68%) and colour (n=36; 77%); n=10; 22% of the paediatricians stated that they 'always' used a ranking system for likelihood of abuse; n=12; 35% of those surveyed 'sometimes' estimated the size of the bruise. Results showed that paediatric bruise reporting is inconsistent and incomplete for some fields compared with national guidance.

[Bilateral thoracic trauma-"double the trouble"?] / Beidseitiges Thoraxtrauma ­ "double the trouble"?

BACKGROUND: Thoracic trauma is associated with a high morbidity and mortality. Assessing the risk for complications is essential for planning the further treatment strategies and managing resources in thoracic trauma. OBJECTIVE: The aim of the study was to analyze concomitant injuries in unilateral and bilateral rib fractures and pulmonary contusions and evaluate differences in complication rates between the two. MATERIAL AND METHODS: In a retrospective study, data from all patients diagnosed with thoracic trauma at a level I trauma center were analyzed. Bivariate and multivariate analysis were used to examine an association of unilateral or bilateral rib fractures, serial rib fractures, and pulmonary contusions with multiple injuries and outcomes. In addition, multivariate regression analysis was utilized to determine the impact of age, gender and additional injuries on outcome. RESULTS: A total of 714 patients were included in the analysis. The mean Injury Severity Score (ISS) was 19. Patients with an additional thoracic spine injury had a significantly higher incidence of bilateral rib fractures. Pulmonary contusions were associated with younger age. Abdominal injuries were predictors for bilateral pulmonary contusions. Complications occurred in 36% of the patients. Bilateral injuries increased the complication rate up to 70%. Pelvic and abdominal injuries as well as the need for a chest drain were significant risk factors for complications. The mortality rate was 10%, with higher age, head and pelvic injuries as predictors. CONCLUSION: Patients with bilateral chest trauma had an increased incidence of complications and a higher mortality rate. Bilateral injuries and significant risk factors must therefore be considered. Injury of the thoracic spine should be excluded in those patients.

Bleeding Events After Image-Guided Breast Biopsies: Comparison of Patients Temporarily Discontinuing Versus Maintaining Antithrombotic Therapy During Biopsy.

BACKGROUND. Antithrombic (AT) therapy is commonly temporarily discontinued before breast core needle biopsy (CNB), introducing risks of thrombotic events and diagnostic delay. OBJECTIVE. The purpose of this article was to compare the frequency of postbiopsy bleeding events among patients without AT use, patients temporarily discontinuing AT therapy, and patients maintaining AT therapy during breast CNB. METHODS. This retrospective study included 5302 patients (median age, 52 years) who underwent image-guided breast or axillary CNB between January 1, 2014, and December 31, 2019. From January 1, 2014, to December 31, 2016, patients temporarily discontinued all AT therapy for 5 days before CNB; from January 1, 2017, to December 31, 2019, patients maintained AT therapy during CNB. Immediate postbiopsy mammograms were reviewed for imaging-apparent hematoma. Patients were called 24-48 hours after biopsy and asked regarding palpable hematoma and breast bruise. The EMR was reviewed for clinically significant postbiopsy hematoma (i.e., hematoma requiring drainage, primary care or emergency department visit for persistent symptoms, or hospital admission). Bleeding events were compared among groups, including Firth bias-reduced multivariable logistic regression analysis. RESULTS. During CNB, 4665 patients were not receiving AT therapy, 423 temporarily discontinued AT therapy, and 214 maintained AT therapy. Imaging-apparent hematoma occurred in 3% of patients without AT use, 6% of patients discontinuing AT therapy, and 7% of patients maintaining AT therapy (p = .60 [discontinuing vs maintaining]). Palpable hematoma occurred in 2% of patients without AT use, 4% of patients maintaining AT therapy, and 4% of patients discontinuing AT therapy (p = .92 [discontinuing vs maintaining]). Breast bruise occurred in 2% of patients without AT use, 1% of patients discontinuing AT therapy, and 6% of patients maintaining AT therapy (p < .001 [discontinuing vs maintaining]). In multivariable analysis adjusting for age, biopsy imaging modality, needle gauge, number of biopsy samples, and pathologic result, discontinued AT therapy (using maintained AT therapy as reference) was not a significant independent predictor of imaging-apparent hematoma (p = .23) or palpable hematoma (p = .91) but independently predicted decreased risk of bruise (OR = 0.11, p < .001). No patient developed clinically significant postbiopsy hematoma. CONCLUSION. Frequencies of imaging-apparent and palpable hematoma were not significantly different between patients temporarily discontinuing versus maintaining AT therapy. CLINICAL IMPACT. The findings support the safety of continuing AT therapy during CNB. Patients who maintain AT therapy should be counseled regarding risk of bruise.

Effects of certain risk factors on presence and severity of carcass bruising in cattle: A study in Turkey.

The aim of the study was to examine the effects of some pre-slaughter factors on the total carcass bruise severity score and the presence of carcass bruises. Bruises on 1027 cattle carcasses were evaluated with the "The Australian Carcass Bruise Scoring System," and at least one bruise score was determined in 92.7% of the carcasses. The total carcass bruise severity score increased as the animal's age, transport time, and AWACT (the Welfare Impact Score of Stockperson Actions) score increased (P < 0.001). The probability of the presence of carcass bruising increased 2.751 times in the autumn (P = 0.031) and 2.200 times in the summer (P = 0.072) compared to the winter. Carcass bruises tended to be 1.747 times more common in females than males (P = 0.065), and 65.9% less in the Simmental than Brown Swiss breed (P = 0.060). Human contact (OR = 1.685; P = 0.079) and electric goad using (OR = 1.762; P = 0.069) on the slaughter corridor tended to increase the probability of the presence of carcass bruises. In conclusion, to reduce the presence and severity of carcass bruises, it may be beneficial to focus on the improvement of handling and coercion practices applied by the stock person, to slaughter the cattle in the nearest slaughterhouse, and to pay more care to the handling of culled cattle.

[Lung contusion after jumping from a 10 meter tower in a swimming pool]. / Lungenkontusion nach Sprung ins Wasser.

BACKGROUND: Lung contusions often occur in the context of polytrauma, but much less frequently in sports injuries. CASE DESCRIPTION: We report on a 22-year-old patient who presented to our emergency room. On the same day he jumped from a 10 meter tower in a swimming pool and hit the surface of the water with his thorax and abdomen. He complained of pain in the right chest and hemoptysis immediately after the jump.The examination findings remained without further abnormalities.In the chest x-ray no abnormalities were found.The CT thorax with contrast medium revealed homogeneous ground-glass opacities in the middle lobe and less in the ventrobasal upper lobe on the right, consistent with the pulmonary contusion with parenchymal bleeding. In addition, there was a minimal pneumothorax border on the paracardial right side.Bronchoscopy performed on the same day showed evidence of blood in the middle lobe bronchus.The hemoptysis stopped spontaneously. On the 3rd day of the hospital stay, the patient was discharged with stable vital parameters and asymptomatic. CONCLUSION: Hemoptysis immediately after a sports chest injury may occur as a result of pulmonary contusion. In contrast to conventional chest x-rays, computed tomography is of great importance in the diagnosis of pulmonary contusion.

Probability and number of bruises in bovine carcasses according to animal type, handling and transport.

The aim of this study was to evaluate pre-slaughter risk factors on the probability of bruising and the number of bruises in different regions of the bovine carcass. The study evaluated the data from 4061 batches of slaughtered cattle, totalling 199,026 carcasses, from Hereford and Aberdeen Angus animals in crosses with continental European breeds and Zebu cattle. The factors that caused injury were sex, handling conditions (score), vehicle type, vehicle load density (kg/m2), travel time (minutes), travel distance (kilometres), physiological maturity (dentition), animal reactivity (score), and carcass fat (score). The type of vehicle had the greatest influence on the probability of carcass bruising and affected all carcass cuts. More bruising occurred in vehicles with a greater load capacity. A higher chance of bruising was seen in groups of older animals, those with an excitable temperament and, especially, in groups of females. Higher load densities during transport resulted in a greater chance of bruising occurring in all cuts except the hindquarters. Distance and travel time are unstable in the models, but also detrimental, increasing the probability of bruising and the number of bruises in the various cuts. The results of this study suggest that good practices in the welfare, handling and transport of the animals, as well as training the personnel responsible for their handling, should be adopted to minimise the risk of injury at different locations on the carcass.

Over One-Third of Patients With Multiligament Knee Injuries and an Intact Anterior Cruciate Ligament Demonstrate Medial Meniscal Ramp Lesions on Magnetic Resonance Imaging.

PURPOSE: To determine the incidence of ramp lesions and posteromedial tibial plateau (PMTP) bone bruising on magnetic resonance imaging (MRI) in patients with multiligament knee injuries (MLKIs) and an intact anterior cruciate ligament (ACL). METHODS: A retrospective review of consecutive patients surgically treated for MLKIs at 2 level I trauma centers between January 2001 and March 2021 was performed. Only MLKIs with an intact ACL that received MRI scans within 90 days of the injury were included. All MLKIs were diagnosed on MRI and confirmed with operative reports. Two musculoskeletal radiologists retrospectively rereviewed preoperative MRIs for evidence of medial meniscus ramp lesions (MMRLs) and PMTP bone bruises using previously established classification systems. Intraclass correlation coefficients were used to calculate the reliability between the radiologists. The incidence of MMRLs and PMTP bone bruises was quantified using descriptive statistics. RESULTS: A total of 221 MLKIs were identified, of which 32 (14.5%) had an intact ACL (87.5% male; mean age of 29.9 ± 8.6 years) and were included. The most common MLKI pattern was combined injury to the posterior cruciate ligament and posterolateral corner (n = 27, 84.4%). PMTP bone bruises were observed in 12 of 32 (37.5%) patients. Similarly, MMRLs were diagnosed in 12 of 32 (37.5%) patients. A total of 8 of 12 (66.7%) patients with MMRLs demonstrated evidence PMTP bone bruising. CONCLUSIONS: Over one-third of MLKI patients with an intact ACL were diagnosed with MMRLs on MRI in this series. PMTP bone bruising was observed in 66.7% of patients with MMRLs, suggesting that increased vigilance for identifying MMRLs at the time of ligament reconstruction should be practiced in patients with this bone bruising pattern. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Treatment of bruising after injection to reduce cellulite.

BACKGROUND: Cellulite 80%-98% of post-pubertal women and results in cutaneous dimples in the affected area. AIMS: Therapies that target collagenous fibrous septae often provide successful outcomes. MATERIALS & METHODS: Collagenase clostridium histolyticum-aaes (CCH) for injection consists of two collagenases which, under physiologic conditions, disrupt collagen structures by hydrolyzing Type I and III collagen. RESULTS: Subcutaneous CCH was approved in the United States in 2020 for the treatment of moderate-to-severe cellulite in the buttocks of adult women. Although bruising is primarily an aesthetic concern, a conspicuous procedure-induced bruise may limit a patient's social activities and result in hesitation to undergo a similar cosmetic procedure in the future. CONCLUSION: The purpose of this review is to describe the available techniques for hastening bruise resolution and how they apply to resolving bruises associated with a CCH injectable.

Injection Adipocytolysis for Body and Jawline Contouring: Real-World Experience and Treatment Considerations.

BACKGROUND: The role of ATX-101 in submental fat reduction has been well documented; however, its applicability across multiple anatomic areas is to be explored. OBJECTIVES: The authors sought to describe the experience with ATX-101 subcutaneous injections for body and jawline contouring and evaluate its safety. METHODS: This single-arm, single-center observational study included 201 patients who underwent injection adipocytolysis with ATX-101 (area-adjusted dose of 2 mg/cm2) in the jowl, abdomen (upper/lower), thigh (inner/outer/banana roll), arm, anterior periaxillary fat, back (lower/upper/nape/lipoma), knee (anterior/medial), chest, and/or neck. The number of treatment sessions, treatment volumes, doses, injections required for each anatomic area, and associated adverse events were recorded. RESULTS: The mean number of treatment sessions conducted was 1.8. Multiple sessions were common for the jowl (mean: 2.0 and mean volume administered varied significantly between persons receiving 1 or multiple sessions [P = 0.005]). The mean volume and mean number of injections per session were highest in the chest (84.7 mL and 423.5, respectively) and lowest in the jowl (0.8 mL and 4.6, respectively). The chest (0.2 mL) and nape (0.2 mL) received the highest mean ATX-101 dose per injection site per session, whereas the inner thigh (0.11 mL) and upper back (0.11 mL) received the least. Adverse events observed were localized to the injection site. All patients experienced edema after each session, whereas numbness, tenderness, bruising, and paresis were experienced by 99.6%, 94.2%, 33.1%, and 2.6% of patients, respectively. Alopecia was not observed. CONCLUSIONS: ATX-101 was well tolerated for body and jawline contouring.

The injury mechanism correlation between MRI and video-analysis in professional football players with an acute ACL knee injury reveals consistent bone bruise patterns.

PURPOSE: To analyze the MRI features, in particular bone bruises pattern, of Anterior Cruciate Ligament (ACL) injured footballers, and to correlate them with the characteristics of injury mechanism and situation obtained from direct video footage. METHODS: Nineteen professional football (soccer) players that sustained ACL injury while playing during an official match of First League Championship were included in the study. The video of injury was obtained from the Television broadcast. Knee Magnetic Resonance (MRI) was obtained within 7 days from the injury. BB and meniscal lesions were analyzed on MRI, while a video-analysis of mechanisms of ACL injury and injury dynamic were assessed from the videos. RESULTS: The most commonly involved Bone Bruise areas in the knee were the Posterior Lateral Tibial Plateau (LTp) in 16 cases (84%) and the Central Lateral Femoral Condyle (LFc) in 11 cases (58%). Three patients (16%) had bone bruise in the Posterior Medial Tibial Plateau (MTp) while none (0%) had bone bruise in the Medial Femoral Condyle. Based on the bone bruise pattern, 11 (58%) had simultaneous LFc and LTp and were defined "Typical" while 8 (42%) had other locations or no bone bruise and were defined "Atypical". 9 out of 11 injuries (82%) of athletes with "Typical" pattern occurred with a "Pivoting" action", in contrast to only 1 case (12%) in those with "Atypical" bone bruise pattern (p = 0.0055). The most common situational mechanism pattern on video analysis was "pressing" (n = 7) accounting for the 47% of the "indirect" ACL injuries. In terms of movement pattern, ten injuries (52%) occurred during a "Pivoting" movement (7 pressing, 1 dribbling, 1 tackled, 1 goalkeeping), whereas the remaining were classified as "Planting" in four cases, "Direct Blow" in four cases and "Landing". CONCLUSION: A well-defined and consistent bone bruise pattern involving the posterior tibial plateau and central femoral condyle of lateral compartment is present in footballers that sustained non-contact and indirect ACL injuries during pivoting with sudden change of direction/deceleration, while heterogeneous patterns were present in those with direct contact or injury mechanisms involving high horizontal velocity. LEVEL OF EVIDENCE: Level IV.
