The advantages of using simple anatomical diagrams and body charts for locating the injury are self-evident erectile dysfunction which doctor to consult cheap 10 mg levitra visa. It is a simple process to record the position of an injury accurately impotence 10 buy 20mg levitra visa, yet when medical records are reviewed erectile dysfunction in early age discount 20 mg levitra with amex, it is both surprising and disappointing to find only a vague indication of location. Aging Injuries Allotting a specific time or time frame to the infliction of an injury is one of the most frequently requested and most contentious of issues in foren- sic medicine. Injuries inflicted shortly before examination (both of the living and the dead) show no sign of healing. The healing process depends on sev- eral variables, including the site of injury, the force applied, the severity of tissue damage, infection, treatment, etc. Bruises often become more prominent a few hours or even days after infliction because of diffusion of blood closer to the skin surface; on occasion, a recent deep bruise may be mistaken for an older, more superficial lesion. Bruises resolve over a variable period ranging from days to weeks; the larger the bruise, the longer it will take to disappear. The colors of a bruise can include (dependent on the exam- iner) blue, mauve, purple, brown, green, and yellow, and all tints and hues associated with these. Thus, coloration of bruises and the progress and change of color patterns cannot, with the exception of a yellow bruise, which may be considered to be more than 18 hours old, be used to time the injury. It should be emphasized that estimation of bruise age from color photographs is also imprecise and should not be relied on because the color values are not accu- rate (6). This has recently been confirmed in another study (7) that identified great interobserver variability in color matching both in vivo and in photo- graphic reproductions. Abrasions sustained during life are usually red-brown and exude serum and blood, which hardens to form a scab. This scab organizes over a period of days before detaching to leave a pink, usually intact, surface. In the absence of medical intervention, lacerations tend to heal with scar- ring, usually over a period of days or weeks, whereas incisions, the edges of which may be apposed, can heal within a few days, although some may scar significantly. Transient Lesions Swelling, redness, and tenderness, although frequently caused by trauma, are not specific signs of injury. Although it is important to record whether these features are present, it must be remembered that there also may be nontraumatic causes for these lesions (e. Red marks outlining an apparent injury, for example, the imprint of a hand on the slapped face or buttock of a child, should be photographed immediately because such images may fade within an hour or so and leave no residual marks. Bruises The terms contusion and ecchymosis have been used to differentiate between different types of injury that can more simplistically be called bruis- ing. These terms have been used variously to describe different injury sizes but do not enhance understanding of either causation or mechanism of injury and should no longer be used. A hematoma is best used to refer to a collection of blood forming a fluctuant mass under the skin and may be associated with substantial trauma. The difference between that and a standard bruise is that a hematoma may be capable of being aspirated in the same way a collection of Injury Assessment 135 Fig. Bruising is caused when an impact damages blood vessels so that blood leaks into the perivascular tissues and is evident on the skin surface as discoloration. Such discoloration changes in color, shape, and location as the blood pigment is broken down and resorbed. In some cases, although blood vessels may be damaged, there may be no visible evidence on the skin. In certain cases, it may take hours or days for any bruise to become apparent because the blood diffuses through damaged tissue. The blunt force ruptures small blood vessels beneath the intact skin, and blood then escapes to infil- trate the surrounding subcutaneous tissues under the pumping action of the heart (see Fig. In fact, severe blows inflicted after death may cause some degree of bruising, although this is usually only slight.
Other features of skeletal injury suggestive of abuse include the following: • Absence of an appropriate history impotence grounds for annulment philippines order levitra australia. Precise dating of fractures cannot be achieved impotence urban dictionary discount 10 mg levitra with mastercard, although ranges of frac- ture ages are available erectile dysfunction gabapentin 10 mg levitra overnight delivery. Advice from an experienced pediatric radiologist should be sought to assist with dating injuries, to obtain further radiological or other imaging views, and to exclude other causes of skeletal abnormality. Detecting occult injury is particularly important in the younger child and infant and recommended indications for a skeletal survey include the follow- ing (17,25,28,32): • Any child younger than 2 years when there is a suspicion of physical abuse. Differential Diagnosis of Skeletal Injury • Accidental injury—appropriate, consistent history, and prompt presentation. Intracranial Injury There is a high incidence of mortality and morbidity after inflicted head injury, and it is the most common cause of traumatic death in infancy (34). It has been generally accepted from research evidence that serious or fatal injury from accidental injury, other than that sustained in road traffic accidents or falls from major heights, is rare in children under 2 years and that simple skull fractures in accidental trauma have a low risk of intracranial sequelae (26). The mechanism of brain injury is considered to be a whiplash motion of acceleration and deceleration, coupled with a rotational force, during a shak- ing episode of an infant, where the head is unsupported. Shaking alone may lead to brain injury, although in many instances there may be other forms of head trauma, including impact injuries (35,36). Impact may be against a hard surface, leading to external injury and an associated skull fracture, or against a soft surface, with no associated external injury. Hypoxia may also lead to brain injury from impairment of ventilation during chest squeezing, suffoca- tion, or strangulation (26). Retinal hemorrhages are strongly suggestive of abuse when accompanied by intracranial injuries and in the absence of a confirmed history of severe accidental injury. Unilateral or bilateral retinal hemorrhages are present in 75– 90% of cases of shaken baby syndrome (36). Retinal hemorrhages can also be found after severe closed chest injury, asphyxia, coagulation disorders, carbon monoxide poisoning, acute hypertension, sepsis, meningitis, and normal birth (usually disappearing by 2 weeks, rarely persisting to 6 weeks). When shaking injuries are suspected, retinal examination is essential and should include di- rect and indirect ophthalmoscopy preferably by an ophthalmologist. Subhyaloid hemorrhages and local retinal detachment occur earliest, are often peripheral, and are found only by indirect ophthalmology. When intraocular injury is present, subdural hemorrhage is likely, and the presence of retinal detachment and multiple hemorrhages may indicate additional cerebral lacerations or in- tracerebral hemorrhages (35). Children with acute intracranial injury may present with fits, lethargy, irritability, apnea, unconsciousness and signs of shock, a tense fontanelle, increasing head circumference, and low hemoglobin. Children with chronic subdural hematomas may present with poor feeding, failure to thrive, vom- Nonaccidential Injury in Children 173 iting, increasing head circumference, and fits. The presentation may suggest sepsis, meningitis, encephalitis, or toxic or metabolic bone disease. The find- ings of retinal hemorrhages, other signs of abuse, and blood-stained cere- brospinal fluid may assist with the differential diagnosis. Milder forms of shaking may go undetected or present with nonspecific signs that may be minimized by physicians or attributed to a viral illness (36). Injuries arise mainly from blunt trauma (punching, kicking, trampling, or stamping) or sudden acceleration/deceleration injuries (swinging or throw- ing a child into a solid object) and include contusion, laceration, and rupture of solid or hollow viscera. Fabricated or Induced Illness The fabrication or induction of illness in children by a caregiver is referred to by several different terms, most commonly Munchausen syndrome by proxy, factitious illness by proxy or illness induction syndrome.
