Basics of CT Scan Head and Trauma Radiographs
Published in Kajal Jain, Nidhi Bhatia, Acute Trauma Care in Developing Countries, 2023
Ujjwal Gorsi, Chirag Kamal Ahuja
The most common cause of opacities in lung in chest trauma is contusion. On radiograph, pulmonary contusion is seen as focal or multifocal areas of consolidation not contained by segmental boundaries. They commonly involve basal segments. After injury, contusions usually develop within 6 hours and resolve over 3 to 10 days. Acute respiratory distress syndrome (ARDS) or secondary infections should be suspected if lung opacities do not clear or increase in this time frame.
Mammography and Interventional Breast Procedures

A contusion may appear as very subtle, diffuse infiltration of tissues by blood or edema. It produces mild architectural changes with some thickening of the breast trabeculations. If trauma results in a true hematoma, a fairly circumscribed lesion may usually develop in the mammogram (Fig. 19). They usually resolve spontaneously, and permanent architectural distortion is fairly unusual [31]. On rare occasions, architectural distortion and scarring may persist, forming a worrisome spiculated density.
Contusional brain injury and intracerebral haemorrhage
Published in Helen Whitwell, Christopher Milroy, Daniel du Plessis, Forensic Neuropathology, 2021
Contusional and lacerating brain injury are characteristic of blunt head trauma. A contusion is ‘bruising’ of the surface of the brain as a result of damage to the small blood vessels. The pia arachnoid is not breached in contusional injury; however, with lacerating injury both the pia arachnoid and the underlying brain substance are torn. Contusional injury may produce varying sizes of intracerebral haematoma.
Lower limb injuries in an english professional football club: injury analysis and recommendations for prevention

Muscle and ligament tears were the most common types of lower limb injuries recorded in our study. Football players face prominently strenuous physical demands both during training and during the matches. As a result, overuse injuries are understandably inevitable. One study showed that during a 90-min match, professional players cover a mean distance of 10,714 (± 991 m), out of which, 2492 (± 625 m) was at high speed [25]. This overwhelming pace, the highly congested fixture and training schedule, and the lack of sufficient recovery periods, predispose the players to a high risk of muscle strain and tears [19]. In addition, the involvement of dribbling, sprinting and pivoting at high speeds increase the risk of ligamentous injuries [26]. As a result, it would be reasonable to find that muscle and ligament tears were the most prevalent. Other injury types like fractures, lacerations and contusions were also present in our study, mainly due to the nature of this contact sport, which often involves traumatic collisions between players, like tackles and bumps [27].

We found the overall incidence rate of injury to be 43.62% in our study. Lacerations and fractures represented the majority of injuries sustained by bare knuckle boxers, accounting for 79.7% and 13.8% of the total recorded injuries, respectively. Hand fractures specifically represented 6.5% of the injuries sustained. In comparison, Karpman et al. [4] identified an overall injury rate of 49.8% for boxers of Edmonton, Canada, while a rate of 59.5% was found for MMA competitors in the same geographic region. In contrast to our study, these authors classified contusions as injuries. Another study, by Zazryn et al. [5], tracked injuries sustained by 545 boxers in Australia over an 8.5-year period. An overall injury rate of 23.6% was reported. Lacerations represented 64% of injuries – although these almost never occurred on the hands. Fractures of the hand represented only 4.7% of all injuries. Finally, Loosemoore et al. [6] reported on injuries sustained by boxers in Great Britain over a 5-year period of time in both training and competition. The hand and wrist were found to be the most commonly injured, accounting for 33% of injuries. In contrast to our findings, hand fractures amongst these boxers represented only 3.4% of all injuries documented and hand lacerations were effectively non-existent. The majority of reported hand injuries were sprains or ligamentous injuries.
Q-switch nanosecond laser as innovative and instant management for bruises discoloration, a case report

Contusion or Ecchymosis, commonly known as bruising, is considered the most common adverse events of injections, due to the disruption in the dermis and epidermis layers of the skin (4,5) while contusion is not considered medically serious, in comparison with other adverse events such as vascular occlusion, facial bruises might take over two weeks to spontaneously resolve (5). Thus, bruises could contribute to longer downtimes which would be distressing to clients, especially those with more social obligations (4). Moreover, the risk of bruising could deter clients from receiving injectable treatments, especially in the facial area (4). Indeed, facial bruises can affect the client’s satisfaction rate after the procedure, which creates a stressful situation for both the client and provider (6). In fact, hemoglobin released during the hemorrhage poses inflammatory and oxidizing effects, thus treating bruises in the early stages would be helpful in preventing local inflammation signs and symptoms (6). While the risk of bruising is common in all clients, it is more prevalent in those receiving antithrombotic medications such as Aspirin or Warfarin (5). Moreover, the injection technique itself might have an impact on the risk of bruising (4). Traditionally, bruises have been managed using over the counter Vit K preparations, cold compresses, and Arnica cream; however, these treatments do not provide instant results (5).
