Easy bruising and bleeding are commonly seen in primary care. Use of a bleeding assessment tool and a comprehensive history, physical examination, and patient-provided photographs can help identify causes of abnormal bleeding and bruising. Family history can aid diagnosis of a heritable cause. Nonaccidental trauma should be considered, especially in vulnerable populations. Initial laboratory testing includes a complete blood cell count, peripheral blood smear, prothrombin time (PT), international normalized ratio, activated partial thromboplastin time (aPTT), and fibrinogen. Normal PT and aPTT results may indicate a platelet disorder. A normal PT result with a prolonged aPTT result indicates a disorder of the intrinsic coagulation pathway, and a prolonged PT result with a normal aPTT result may indicate a disorder of the extrinsic coagulation pathway. Consultation with a hematologist is recommended when initial evaluation indicates a bleeding disorder or when suspicion remains high despite a normal laboratory workup result.

Background: The thresholds of mechanical inputs for bruising caused by blunt impact are important in the fields of machine safety and forensics. However, reliable data on these thresholds remain inadequate owing to a lack of in vivo experiments, which are crucial for investigating the occurrence of bruising. Since experiments involving live human participants are limited owing to ethical concerns, finite-element method (FEM) simulations of the bruising mechanism should be used to compensate for the lack of experimental data by estimating the thresholds under various conditions, which requires clarifying the mechanism of formation of actual bruises. Therefore, this study aimed to visualize the mechanism underlying the formation of bruises caused by blunt impact to enable FEM simulations to estimate the thresholds of mechanical inputs for bruising., Methods: In vivo microscopy of a transparent glass catfish subjected to blunt contact with an indenter was performed. The fish were anesthetized by immersing them in buffered MS-222 (75-100 mg/L) and then fixed on a subject tray. The indenter, made of transparent acrylic and having a rectangular contact area with dimensions of 1.0 mm × 1.5 mm, was loaded onto the lateral side of the caudal region of the fish. Blood vessels and surrounding tissues were examined through the transparent indenter using a microscope equipped with a video camera. The contact force was measured using a force-sensing table., Results: One of the processes of rupturing thin blood vessels, which are an essential component of the bruising mechanism, was observed and recorded as a movie. The soft tissue surrounding the thin blood vessel extended in a plane perpendicular to the compressive contact force. Subsequently, the thin blood vessel was pulled into a straight configuration. Next, it was stretched in the axial direction and finally ruptured., Conclusion: The results obtained indicate that the extension of the surrounding tissue in the direction perpendicular to the contact force as well as the extension of the thin blood vessels are important factors in the bruising mechanism, which must be reproduced by FEM simulation to estimate the thresholds., (© 2024.

Bruising rarely presents in infants younger than 9 months who are not ambulatory and is more prevalent among children beginning to walk, or "cruisers." We present the case of a healthy 3-month-old infant with asymptomatic, symmetric, bilateral, large bruises on the bony chest sparing the mid-chest/sternum with a negative non-accidental trauma work-up. The noted pattern of bruises matched the bilateral shoulder straps of a 5-point harness of the car seat belt designed for infants. Awareness of this unique pattern of bruises will help elicit a better-informed history to guide care in an appropriate setting., (© 2024 The Authors.

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., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

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., (© 2023. The Author(s).)

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.

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.

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/m 2 ), 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., (© 2022.

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., (© 2023. The Author(s).)

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., (© 2023 The Authors.

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., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Ltd.

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., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

A bruise in a premobile infant is an uncommon finding and often results in referral to the paediatric or emergency departments, acknowledging the potential for physical abuse in this vulnerable cohort. Our role as clinicians is to undertake a thorough assessment, consider potential differentials and organise appropriate investigations, with involvement of the wider multidisciplinary team. In this article, we use a case vignette to discuss how one would approach a bruise in the premobile infant including the evidence base., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

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 Author(s) 2022. Published by Oxford University Press on behalf of The Aesthetic Society.)

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., (Copyright © 2022 Arthroscopy Association of North America.

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.

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., (© 2022 The Author.

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., (© 2022.

Purpose: Lateral meniscus posterior root tears (LMPRTs) are commonly found in patients with anterior cruciate ligament (ACL) injuries. However, risk factors for LMPRTs are not well known. This study was designed to systematically review the available evidence regarding risk factors associated with LMPRTs., Methods: The PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for papers containing the key words "lateral meniscus posterior root tears", "LMPRTs" and "risk factor". Inclusion screening, data extraction, and quality assessment of the included articles were conducted independently by two authors. Statistical analysis was conducted to determine risk factors for LMPRTs., Result: Seventeen studies with a total sample size of 6, 589 patients were identified. The pooled prevalence of LMPRTs was 9.6% (range, 5.1-33.8%) for ACL injury. Significant risk factors included a patient age of < 30 [OR = 1.4, 95% CI (1.07, 1.84), p = 0.01], male sex [OR = 1.50, 95% CI (1.24,1.81), p = 0.01], higher body mass index (BMI) [MD = 0.45, 95% CI (0.13, 0.76), p < 0.01], higher lateral posterior tibial slope (LPTS) [MD = 2.22, 95% CI (1.37, 3.07), p < 0.01], deep sulcus sign [OR = 5.76, 95% CI (1.35, 24.52), p < 0.01] and bone bruises on lateral femoral condyle [OR = 4.88, 95% CI (1.27, 18.77), p < 0.01], lateral meniscal extrusion > 1 mm [OR = 5.56, 95% CI (1.52, 20.29), p < 0.01] and > 3 mm [OR = 12.91 95% CI (1.28, 130.01), p < 0.01], medial meniscal tears [OR = 1.40, 95% CI (1.12, 1.75), p < 0.01], and medial ramp lesions [OR = 2.29, 95% CI (1.35, 3.89), p < 0.01]., Conclusion: Age below 30, male, higher BMI, higher LPTS, deep sulcus sign, bone bruises on lateral femoral condyle, lateral meniscal extrusion, medial meniscal tear, and medial ramp lesion are risk factors for LMPRTs., Level of Evidence: Level IV., (© 2022.

Introduction: Albeit described since 1763, cardiac contusions is still an under-recognised clinical condition in the acute care setting. This evidence-based review aims to provide an overview of the topic by focusing on etiopathogenesis, classification and clinical presentation of patients with cardiac contusions, as well as on the diagnostic work-up and therapy options available for this subset population in the acute care setting., Methods: A targeted research strategy was performed using PubMed, MEDLINE, Embase and Cochrane Central databases up to June 2022. The literature search was conducted using the following keywords (in Title and/or Abstract): ("cardiac" OR "heart" OR "myocardial") AND ("contusion"). All available high-quality resources written in English and containing information on epidemiology, etiopathogenesis, clinical findings, diagnosis and management of cardiac contusions were included in our research., Results: Biochemical samples of cardiac troponins together with a 12‑lead ECG appear to be sufficient screening tools in hemodynamically stable subjects, while cardiac ultrasound provides a further diagnostic clue for patients with hemodynamic instability or those more likely to have a significant cardiac contusion., Conclusions: The management of patients with suspected cardiac contusion remains a challenge in clinical practice. For this kind of patients a comprehensive diagnostic approach and a prompt emergency response are required, taking into consideration the degree of severity and clinical impairment of associated traumatic injuries., Competing Interests: Declaration of Competing Interest the authors declare they have no conflicts of interest, financial or otherwise to disclose., (Copyright © 2022 Elsevier Inc.

Bruising or bleeding in a child can raise the concern for child abuse. Assessing whether the findings are the result of trauma and/or whether the child has a bleeding disorder is critical. Many bleeding disorders are rare, and not every child with bruising/bleeding that may raise a concern for abuse requires an evaluation for bleeding disorders. However, in some instances, bleeding disorders can present in a manner similar to child abuse. Bleeding disorders cannot be ruled out solely on the basis of patient and family history, no matter how extensive. The history and clinical evaluation can be used to determine the necessity of an evaluation for a possible bleeding disorder, and prevalence and known clinical presentations of individual bleeding disorders can be used to guide the extent of laboratory testing. This clinical report provides guidance to pediatricians and other clinicians regarding the evaluation for bleeding disorders when child abuse is suspected., (Copyright © 2022 by the American Academy of Pediatrics.)

Child abuse might be suspected when children present with cutaneous bruising, intracranial hemorrhage, or other manifestations of bleeding. In these cases, it is necessary to consider medical conditions that predispose to easy bleeding or bruising. When evaluating for the possibility of bleeding disorders and other conditions that predispose to hemorrhage, it is important for pediatricians to consider the child's presenting history, medical history, and physical examination findings before initiating a laboratory investigation. Many medical conditions can predispose to easy bleeding. Before ordering laboratory tests for a disease, it is useful to understand the biochemical basis and clinical presentation of the disorder, condition prevalence, and test characteristics. This technical report reviews the major medical conditions that predispose to bruising or bleeding and should be considered when evaluating for abusive injury., (Copyright © 2022 by the American Academy of Pediatrics.)

Thoracic injuries are significant causes of morbidity and mortality in trauma patients. Traumatic pulmonary contusion and/or laceration are often observed in patients with chest trauma, explosion injuries or a shock wave associated with penetrating trauma. A pulmonary contusion is an injury to the lung parenchyma without actual structural damage. As a result of damage to alveoli and capillaries, it results in leakage of blood and other interstitial fluids across the alveolar-capillary membrane into lung tissue and alveolar space. Since oxygenated air can not enter into fluid-filled alveoli, hypoventilation and decreased perfusion by reflux vasoconstriction result in hypoxemia and hypercapnia. Pulmonary laceration is a lung injury with disruption of the architecture of the lung, while pulmonary contusion does not. There is almost always concurrent pulmonary contusion, and pneumothorax, hemothorax, or hemopneumothorax. In addition, pulmonary laceration can be a cause of forming a cyst or hematoma, which usually disappears over a period of weeks or months. However, pneumatocele can occur in some cases when lacerations are enlarged with air-filled cavity. It is important for thoracic surgeons to understand pathophysiology of traumatic lung injury, and to know the diagnosis and treatment.

Background: Blunt pulmonary contusions are associated with severe chest injuries and are independently associated with worse outcomes. Previous preclinical studies suggest that contusion progression precipitates poor pulmonary function; however, there are few current clinical data to corroborate this hypothesis. We examined pulmonary dynamics and oxygenation in subjects with pulmonary contusions to evaluate for impaired respiratory function., Methods: A chest injury database was reviewed for pulmonary contusions over 5 years at an urban trauma center. This database was expanded to capture mechanical ventilation parameters for the first 7 days on all patients with pulmonary contusion and who were intubated. Daily [Formula: see text]:[Formula: see text], oxygenation indexes (OI), and dynamic compliances were calculated. Pulmonary contusions were stratified by severity. The Fisher exact and chi square tests were performed on categorical variables, and Mann-Whitney U-tests were performed on continuous variables. Significance was assessed at a level of 0.05., Results a Total of: 1,176 patients presented with pulmonary contusions, of whom, 301 subjects (25.6%) required intubation and had available invasive mechanical ventilation data. Of these, 144 (47.8%) had mild-moderate pulmonary contusion and 157 (52.2%) had severe pulmonary contusion. Overall injury severity score was high, with a median injury severity score of 29 (interquartile range, 22-38). The median duration of mechanical ventilation for mild-moderate pulmonary contusion was 7 d versus 10 d for severe pulmonary contusion ( P = .048). All the subjects displayed moderate hypoxemia, which worsened until day 4-5 after intubation. Severe pulmonary contusion was associated with significantly worse early hypoxia on day 1 and day 2 versus mild-moderate pulmonary contusion. Severe pulmonary contusion also had a higher oxygenation index than mild-moderate pulmonary contusion. This trend persisted after adjustment for other factors, including transfusion and fluid administration., Conclusions: Pulmonary contusions played an important role in the course of subjects who were acutely injured and required mechanical ventilation. Contusions were associated with hypoxemia not fully characterized by [Formula: see text]: [Formula: see text], and severe contusions had durable elevations in the oxygenation index despite confounders., Competing Interests: The authors have disclosed no conflicts of interest.

Infants (children <12 months of age) are maltreated at more than twice the rate of any other child age group, and infants die because of maltreatment at 3 times the rate of any other age group in childhood. The incidence of hospitalization for serious physical abuse in children also is highest for infants. Successful recognition of medically mild signs of physical abuse in infants, such as certain bruising patterns, can, therefore, lead to lifesaving interventions. The importance of the recognition of medically mild injuries due to physical abuse is underscored by the finding that a high percentage of infants (27.5%) hospitalized with serious physical abuse were found to have previously sustained milder injuries, such as bruising. Clinicians must be aware of patterns of bruising suggestive of abuse to distinguish between infants who have been abused and those who have been accidentally injured. To maximize the likelihood that abused infants will be identified and protected, as well to minimize the likelihood that an accidentally injured infant will be mischaracterized as abused, the application of an evidence-based approach to the evaluation of bruised infants should be applied. A consistent, evidence-based practice in this setting also may reduce the influence of racial and socioeconomic bias and decrease disparities in care., (© American Academy of Pediatrics, 2022.

Methods: Six children's hospitals identified infants with an initial injury and recurrent injury over a 1-year period using 2 methods: (1) diagnostic code method - infants 6 months or younger presenting with at least 1 diagnostic code for injury were tracked for 12 months to determine the frequency of recurrent injury, and (2) consult method - all available medical records of children 18 months or younger seen for an inpatient consultation for suspected child abuse were reviewed to identify history of a first injury at 6 months or younger., Results: Using the diagnostic code method, 682 unique infants were identified with initial injuries, most commonly fractures (37.0%), bruising/ecchymosis (35.9%), and superficial injuries (28.3%). Forty-two infants (6.2%) returned with a second injury, and no demographic factors were significantly associated with the likelihood of a second injury. Using the consult method, 37 of 342 consults (10.8%) were identified as having a history of at least 1 initial injury. Of the initial injuries identified, the most common was bruising/ecchymosis (64.9%). The number of injuries identified with either method varied significantly across hospitals, as did completion of skeletal surveys for infants with bruising (range, 4.5%-71.1%; P < 0.001) and any injury (range, 4.4%-62.7%; P < 0.001)., Conclusions: Our study demonstrates that young infants who experience 1 injury often experience a second injury. There exists significant variability in the identification of injury and the completion of skeletal surveys across a network of 6 children's hospitals. A standardized quality improvement approach may improve identification of injury and reduce the variability in practice observed., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: The objective of the study is to investigate diagnostic and clinical processes performed for cardiac contusion in patients with blunt thoracic trauma., Methods: This study was conducted retrospectively on 65 patients admitted with isolated blunt thoracic trauma to the Emergency Medicine Department. The CT images, the cardiac enzyme levels, the periodic 4-h follow-up electrocardiography (ECGs) in the emer-gency department, and the results of echocardiography, performed at admission and when required according to the clinical status, were investigated. The 1-h and 4-h high-sensitivity troponin I levels were studied, and values above 0.04 ng/ml were considered as positive., Results: Sixty-five patients with isolated thoracic trauma were included in the study, 23 (35.38%) had pulmonary and cardiac contu-sions both. In 23 (35.38%) patients, pulmonary contusion had been present, and cardiac contusion had not been identified at the initial evaluation. However, during clinical follow-up, troponin became positive, dysrhythmia developed, and the trauma affected the heart in four of these patients. In six (9.24%) patients, cardiac contusion was identified without pulmonary contusion. In 13 (20%) patients, no cardiac or pulmonary contusion was identified. troponin elevation was detected in 10 patients without a diagnosis of cardiac contusion who had a pulmonary contusion, hemothorax, and/or pneumothorax at the time of hospital admission and then with normal troponin levels at 4-h control. We found that there was a statistical agreement between cardiac contusion and troponin-ECG results at 4th h., Conclusion: We advise that all blunt thoracic trauma patients should be screened for cardiac contusion by continuous ECG monitoring and troponin levels.

Deliberate airway obstruction is a well-recognised form of child abuse and one of the most common causes of death in cases of child homicide. Although classical signs such as petechial haemorrhages can be helpful in raising the suspicion of mechanical asphyxia, they are not always present. Therefore, distinguishing between bruising caused by accidents, medical conditions or non-accidental injury remains challenging. We aimed to characterise bruising patterns which are potentially more consistent with deliberate airway obstruction by means of an experimental modelling study. The first results of our project were previously published and demonstrated that bruising anywhere on the head may be consistent with deliberate upper airway obstruction. In this paper, we present the findings of a questionnaire carried out during the modelling to assess participants' perception of force and consider how variables such as age, use of adjuncts and force distribution may affect bruising patterns in deliberate airway obstruction. Statistical analysis of our results showed that participants felt they were using less force in scenarios involving the infant rather than the child resuscitation dummy as well as when using adjuncts, meaning marks are likely to be more subtle. Therefore, in such cases it is important to examine for other signs of asphyxiation (such as petechiae) and consider the possibility that adjuncts might have been used which could make picking up localised injuries more difficult. Our results also showed that participants often felt force was not distributed evenly across the digits, reporting the greatest force through either the thumb in isolation or the thumb plus another digit in up to nearly 50% of cases. This suggests that just one or two bruises may be consistent with deliberate airway obstruction., (Crown Copyright © 2022. Published by Elsevier Ltd. All rights reserved.)

Purpose: The presence of soft tissue injury in pediatric supracondylar humerus fractures (SCHFs) has been shown to be an independent predictor of any neurovascular injury. Potentially expanding this concept, the specific neurovascular structure injured around the elbow is thought to be dependent upon the direction and magnitude of fracture displacement and subsequent soft tissue injury. Therefore, it was hypothesized that the bruise location following SCHF is indicative of the anatomic location of maximal soft tissue injury and therefore is a specific prognosticator of which neurovascular structure may be injured., Methods: Retrospective chart review of all SCHFs treated at a tertiary pediatric hospital from 2007 to 2017 collected information on bruise location, neurovascular injury patterns, and outcomes. Bruise location was classified as anterior, anterolateral, anteromedial, or posterior. Injury radiographs were reviewed by a blinded pediatric orthopaedic surgeon to neurovascular structure injured., Results: Of 2845 SCHFs identified, 267 (9.4%) had concomitant neurovascular injury-of which 128 (47.9%) met inclusion criteria. Among the vascular injuries, all bruising was anteromedial (28/45, 62.2%, P<0.05) or anterior (17/45, 37.8%, P>0.05). Fractures with anteromedial bruising correlated with median nerve injury (24/27, 88.9%, P<0.05), whereas fractures with anterolateral bruising correlated with radial nerve injuries (24/25, 96.0%, P<0.05). Bruising or radiographic evaluation correctly identified 60.2% and 64.1% of neurovascular injuries, respectively, whereas the combination identified 82.0% of neurovascular injuries correctly. Bruise location identified 23 neurovascular injuries not predicted by radiographic evaluation alone., Conclusion: Bruise location is an important physical examination finding that can be used as an adjunct to improve the diagnostic accuracy of neurovascular injury in SCHFs in conjunction with neurovascular physical examination and radiographic evaluation. SCHFs with anterior or anteromedial bruising should raise concern for vascular injury. In addition, anteromedial bruising is predictive of a median nerve injury and anterolateral bruising is predictive of radial nerve injury. This adjunct diagnostic is particularly helpful in a noncooperative child or if performed by a clinician with limited experience in diagnosing neurovascular injuries or interpreting pediatric elbow radiographs., Level of Evidence: Level IV, case series., Competing Interests: J.G.S. receives research funding from OrthoPediatrics, served as a board member of Pediatric Society of North America (POSNA) and research support from IONIS Pharmaceuticals.

Introduction: A challenge of minimally invasive esthetic procedures (eg, injectables and threads) is managing adverse events (AEs), such as post-procedural bruising. Implementation of post-procedural camouflage therapy may minimize the appearance of bruising and mitigate AEs., Aims: A physician and patient user experience program was designed to evaluate the safety and efficacy of a concealer for the cosmetic camouflage of post-procedural bruising., Methods: Thirty female patients with a mean age of 42.03 years participated in the program. Physicians and patients completed various questionnaires regarding the safety and efficacy of the investigational product (Dermablend™ Professional Cover Care Full Coverage Concealer) at three timepoints: Visit 1 (Day 0); Visit 2 (Day 3); and Visit 3 (Day 14 ± 3 days)., Results: All patients presented with mild-to-moderate bruising following treatment with either esthetic injectables or threads. On average, users required 1.55 (SD: 0.72) coats to sufficiently cover their bruise(s). After application of the concealer, 78.18% of users displayed "clear skin with no signs of erythema" and 21.82% displayed "almost clear skin, with slight redness." No physician-reported AEs related to product use were reported throughout the evaluation period. No allergic reactions upon application nor intolerance to the product after prolonged use (ie, up to 14 days ± 3 days) was observed. Throughout the duration of use, 98.81% of subjects were at least slightly satisfied with results. At Visits 1 and 2, 100% of physicians were at least slightly satisfied with results., Conclusion: Cosmetic concealer use can ameliorate the post-procedural experience for patients presenting with mild-to-moderate bruising., (© 2021 Wiley Periodicals LLC.)

Objectives: The aim of this study was to determine how reliable scalp bruising and soft tissue swelling/cephalohematomas (STS) are for underlying young child skull fractures., Methods: This was a retrospective clinical and imaging review from 2011 to 2012 of children younger than 4 years with skull fractures from 2 tertiary care hospitals. Imaging was reread by 3 pediatric radiologists. Descriptive statistics were utilized. The retrospective review had institutional review board approval., Results: We identified 218 subjects for review: 210 unintentional and 8 abusive. One hundred forty-three had available 3-dimensional computed tomography reconstructions: 136 unintentional and 7 abused. Two-thirds were younger than 1 year. Twelve subjects had visible scalp bruising, but 73% had clinically and 93% radiologically apparent fracture-associated STS. There was no difference in clinical STS with simple (79%) versus complex (68%) fractures. Nor was there difference in subjects with fractures from minor (77%) versus major (70%) trauma. Unintentionally injured infants did not differ from abused for detectable STS (74% vs 50%). Parietal and frontal bones most frequently sustained fractures and most consistently had associated STS., Conclusions: Clinically apparent STS is present in approximately three-fourths of children with skull fractures. It may not be important to consistently identify skull fractures in unintentionally injured children. Point-of-care ultrasound may be adequate. For abuse concerns, it is important to identify skull fractures as evidence of cranial impacts and intracranial hemorrhages. The most sensitive, widely available imaging technique, cranial computed tomography scan with 3-dimensional skull reconstruction, should be utilized. Scalp bruising is present in a minority of young children with skull fractures. Its absence does not exclude cranial impact injury., Competing Interests: Disclosure: J.B.M., J.P.O., S.L.D., E.C.B.B., R.T.W., C.J., and K.W.F. have provided medical legal consultation and testimony.

Abstract: Pinna bruising can be associated with abuse, but can also be due to accidental injury. We present 3 cases of pinna bruises and discuss features associated with accidental and nonaccidental injury. Attention to the history, the pattern of bruising, and any other findings identified on a careful, thorough examination will help differentiate the two., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

Background:  Thorax trauma frequently occurs in which injuries to the bony chest, lung contusions (LCs), and others are diagnosed. The significance of this violation is described very differently and is mostly based on monocentric data., Methods:  A retrospective analysis of the TraumaRegister DGU ® (TR-DGU) dataset (Project 2014-062) was performed between 2009 and 2014 (injury severity score [ISS] ≥ 16, primary admission to a trauma center, no isolated traumatic brain injury). Patients with LC (Abbreviated Injury Scale [AIS] 3 + 4) were compared with the control group, and an analysis of different age groups was performed., Results:  A total of 49,567 patients were included, thereunder 14,521 (29.3%) without relevant thoracic trauma (TT); 95.9% blunt traumas. 18,892 patients (38.1%) had LC and 14,008 (28.3%) had severe LC with AIS 3 + 4; thereunder 72.7% males. For severe LC, the average age was the lowest (44.7 ± 19.7 years) and ISS the highest (30.4 ± 12.1 points).Intubation, intensive care, (multi-) organ failure, sepsis, and extrathoracic injuries were most common in severe LC. Shock, chest tubes, further thoracic injuries, and patient death occurred most frequently in TT without LC.Younger patients showed a higher incidence of LC than the older ones; however, high patient age was a highly significant risk factor for the development of complications and poor outcome., Conclusion:  Since LC was present in almost 40% of the severely injured and was related to higher morbidity, LC should be detected and managed at the earliest possible time.

The current standard technique for cardiopulmonary resuscitation (CPR), initially described in the early 1960s, has quickly become the expected response for all persons found without a pulse or respiration. Despite the potentially lifesaving properties of external cardiac massage, the mainstay of resuscitation, it consists of repeated blunt force trauma to the chest, which can lead to extensive traumatic skeletal and nonskeletal injuries. Numerous autopsy-based studies have documented the incidence and patterns of rib and sternal fractures associated with attempted CPR, but there is relatively little data on the incidence and severity of nonskeletal CPR-related injuries. We reviewed reports from 1878 autopsies performed between September 2017 and December 2019 (inclusive), for documentation of CPR-related injuries. Among these cases, there were 93 cases with resuscitation-related nonskeletal injuries. The most common type of injury identified were visceral contusions, documented in 57.0% of cases. These contusions predominantly involved the heart, lungs, neck soft tissue, and surrounding structures. Resuscitation-related lacerations were seen in 17.2% of the cases, most predominantly involving the pericardium, heart, and liver. Statistical analysis of the data demonstrated that lacerations were more likely to be seen in females and with associated sternal fractures. Additionally, hemothoraces were present in 34.4% of cases and hemopericardium was seen in 8.6% of cases. This study provides additional documentation of the range, severity, and incidence of various types of resuscitation-related visceral injuries to better assist autopsy pathologists in distinguishing these injuries from other antecedent traumatic injuries., (© 2021 American Academy of Forensic Sciences.)
