Head injuries range from minor scalp injuries to serious traumatic brain injuries. The most common causes of traumatic brain injury are motor vehicle accidents, violence, and falls. Damage to the brain occurs through primary injury at the time of impact and secondary injury over subsequent hours and days from swelling or bleeding. Skull fractures are classified based on their location and characteristics. Diagnosis involves physical examination, imaging like CT or MRI to identify injuries, and monitoring for complications. Treatment depends on the severity and location of the injury, and may involve surgery, antibiotics, reducing swelling and pressure on the brain.
A head injury is any trauma to the scalp, skull, or brain. The injury may be only a minor bump on the skull or a serious brain injury. Head injury can be either closed or open (penetrating). A closed head injury means you received a hard blow to the head from striking an object, but the object did not break the skull.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.

Head injury.pptx
1.
2. Head Injury
Head injury is a broad classification that includes injury to the scalp,
skull, or brain.
Traumatic brain injury is the most serious form of head injury.
The most common causes of traumatic brain injury are motor vehicle
crashes, violence, and falls.
Groups at highest risk for traumatic brain injury are persons age 15 to
24 years and males, who suffer traumatic brain injury at a rate almost
twice that of females.
The very young (under 5) and the very old (over 75) are also at
increased risk.
3. Damage to the brain from traumatic injury takes two forms: primary
injury and secondary injury.
Primary injury is the initial damage to the brain that results from the
traumatic event.
This may include contusions, lacerations, and torn blood vessels from
impact, acceleration/deceleration, or foreign object penetration.
Secondary injury evolves over the ensuing hours and days after the
initial injury and is due primarily to brain swelling or ongoing
bleeding.
4. An injured brain is different from other injured body areas due to its
unique characteristics.
It resides within the skull, which is a rigid closed compartment.
Unlike an injured ankle, in which the covering skin expands with
swelling, the confines of the skull do not allow for the expansion of
cranial contents.
Thus, any bleeding or swelling within the skull increases the volume
of contents within a container of fixed size and so can cause increased
intracranial pressure (ICP).
5. If the increased pressure is high enough, it can cause a downward or
lateral displacement of the brain through or against the rigid structures
of the skull.
This causes restriction of blood flow to the brain, decreasing oxygen
delivery and waste removal.
Cells within the brain become anoxic and cannot metabolize properly,
producing ischemia, infarction, irreversible brain damage, and
eventually brain death
8. SCALP INJURY
Isolated scalp trauma is generally classified as a minor head injury.
Because its many blood vessels constrict poorly, the scalp bleeds
profusely when injured.
Trauma may result in an abrasion (brush wound), contusion,
laceration, or hematoma beneath the layers of tissue of the scalp
(subgaleal hematoma).
Large avulsions of the scalp may be potentially life-threatening and are
true emergencies.
9. Diagnosis of any scalp injury is based on physical examination,
inspection, and palpation.
Scalp wounds are potential portals of entry of organisms that cause
intracranial infections.
Therefore, the area is irrigated before the laceration is sutured to
remove foreign material and to reduce the risk for infection.
Subgaleal hematomas (hematomas below the outer covering of the
skull) usually absorb on their own and do not require any specific
treatment.
10. SKULL FRACTURES
A skull fracture is a break in the continuity of the skull caused by
forceful trauma.
It may occur with or without damage to the brain.
Skull fractures are classified as linear, comminuted, depressed, or
basilar.
A fracture may be open, indicating a scalp laceration or tear in the
dura , or closed, in which the dura is intact.
11. Clinical Manifestations
The symptoms, apart from those of the local injury, depend on the
severity and the distribution of brain injury.
Persistent, localized pain usually suggests that a fracture is present.
Fractures of the cranial vault may or may not produce swelling in the
region of the fracture; therefore, an x-ray is needed for diagnosis.
12. Fractures of the base of the skull tend to traverse the paranasal sinus of
the frontal bone or the middle ear located in the temporal bone.
Thus, they frequently produce hemorrhage from the nose, pharynx, or
ears, and blood may appear under the conjunctiva.
An area of ecchymosis (bruising) may be seen over the mastoid
(Battle’s sign).
Basal skull fractures are suspected when cerebrospinal fluid escapes
from the ears (CSF otorrhea) and the nose (CSF rhinorrhea).
13. A halo sign (a blood stain surrounded by a yellowish stain) may be
seen on bed linens or the head dressing and is highly suggestive of a
CSF leak.
Drainage of CSF is a serious problem because meningeal infection can
occur if organisms gain access to the cranial contents through the nose,
ear, or sinus through a tear in the dura.
Bloody CSF suggests a brain laceration or contusion.
14. Assessment and Diagnostic Findings
Although a rapid physical examination and evaluation of neurologic
status detect the more obvious brain injuries, a computed tomography
(CT) scan can detect less apparent abnormalities by the degree to
which the soft tissue absorbs the x-rays.
It is a fast, accurate, and safe diagnostic study that shows the presence,
nature, location, and extent of acute lesions.
15. It is also helpful in the ongoing management of patients with head
injury as it can disclose cerebral edema, contusion, intracerebral or
extracerebral hematoma, subarachnoid and intraventricular
hemorrhage, and late changes (infarction, hydrocephalus).
Magnetic resonance imaging (MRI) is used to evaluate patients with
head injury when a more accurate picture of the anatomic nature of the
injury is warranted and when the patient is stable enough to undergo
this longer diagnostic study.
16. Cerebral angiography may also be used; it identifies supratentorial,
extracerebral, and intracerebral hematomas and cerebral contusions.
Lateral and anteroposterior views of the skull are obtained.
17. Medical Management
Nondepressed skull fractures generally do not require surgical
treatment; however, close observation of the patient is essential.
Nursing personnel may observe the patient in the hospital, but if no
underlying brain injury is present, the patient may be allowed to
return home.
If the patient is discharged home, specific instructions must be given to
the family.
Many depressed skull fractures are managed conservatively; only
contaminated or deforming fractures require surgery.
18. If surgery is necessary, the scalp is shaved and cleansed with copious
amounts of saline to remove debris.
The fracture is then exposed.
After the skull fragments are elevated, the area is débrided.
Large defects can be repaired immediately with bone or artificial
grafts; if significant cerebral edema is present, repair of the defect can
be delayed for 3 to 6 months.
19. Penetrating wounds require surgical débridement to remove foreign
bodies and devitalized brain tissue and to control hemorrhage.
Antibiotic treatment is instituted immediately, and blood component
therapy is administered if indicated.
20. As stated previously, fractures of the base of the skull are serious
because they are usually open (involving the paranasal sinuses or
middle or external ear) and result in CSF leakage.
The nasopharynx and the external ear should be kept clean.
Usually a piece of sterile cotton is placed loosely in the ear, or a sterile
cotton pad may be taped loosely under the nose or against the ear to
collect the draining fluid.
21. The patient who is conscious is cautioned against sneezing or blowing
the nose.
The head is elevated 30 degrees to reduce ICP and promote
spontaneous closure of the leak, although some neurosurgeons prefer
that the bed be kept flat.
Persistent CSF rhinorrhea or otorrhea usually requires surgical
intervention.
Thanking you.
