Wounds and Injuries
Brain Injuries
Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

Trauma sites and clinical features associated with acute hyperextension spinal cord injury without bone damage--relationship between trauma site and severity. (1/21)
To elucidate whether a relationship exists between the site of trauma and severity of acute hyperextension spinal cord injury without bone damage, we examined the clinical features of 25 male and 10 female patients aged 13 to 88 years. None of the patients had vertebral damage such as fracture and dislocation. The site of impact was classified as the buccal, forehead, or mandibular region. The neurological findings were assessed according to Frankel's classification at admission and at follow up after 3 months or more to assess outcome. Eleven patients suffered trauma in the buccal region, one patient in Frankel's grade B, three in grade C, and seven in grade D at admission. All 11 of these patients showed an improvement of one grade or more to an outcome of C in one patient, D in one, and E in nine. Trauma occurred at the forehead region in 18 patients, four in grade B, 10 in grade C, and four in grade D. Improvement was seen at follow up by one grade or more to C in one patient, D in 10, and E in seven. Trauma occurred at the mandibular region in six patients, four in grade B and two in grade C. Four of these patients showed improvement of one grade or more to grade B in one, grade C in four, and grade E in one. Overall, seven patients had poor outcomes, five of whom suffered trauma to the mandibular region, indicating that impact to the mandibular region tends to have an unfavorable clinical outcome. Our findings indicate that the site of trauma greatly influences the severity of hyperextension spinal cord injury. (+info)Spontaneous bone regeneration of the mandible in an elderly patient: a case report and review of the literature. (2/21)
Spontaneous bone regeneration is an unexpected phenomenon that may take place in large mandibular defects secondary to trauma and tumor resection. One explanation for this unusual healing course is that it may be derived from the mechanism of fracture healing. A review of the literature presents several factors that may influence this process, such as the presence of periosteum and bony fragments, mandibular stabilization, soft tissue protection, the presence of infection, and a young age. Previous reports of spontaneous mandibular regeneration have all taken place in relatively young patients (5-35 years old). This paper reports a case of spontaneous bone regeneration in a 58-year-old woman who sustained an injury to her mandible from an explosive blast, and presents some explanations on how such an event could take place. (+info)THE TREATMENT OF FRACTURES OF THE MANDIBLE. (3/21)
One hundred and eleven cases of mandibular fracture in 67 patients who were seen at the San Francisco General Hospital from 1960 to 1962 were reviewed. With the exception of two cases in which displaced fragments interfered with the mandibular range of motion, condylar fractures were successfully treated with closed reduction. Undisplaced fractures of the angle were treated successfully by intermaxillary fixation alone, but the significantly displaced fractures were treated by open reduction and interosseous wire fixation. Fractures of the anterior body and midbody were usually treated with closed reduction if adequate teeth were present for satisfactory intermaxillary fixation. Some fractures of the anterior body, particularly those in the region of the symphysis require open reduction because of the strong pull of the muscles in that area. In this series of patients, clinical infection and non-union were most commonly associated with fractures communicating with teeth. If open reduction is necessary, the results in this series suggest that it should be delayed until the oral tract left by extraction is healed. Prophylactic antibiotics did not appear to be of value in preventing infection or non-union in this small series of patients, although sufficient data were not available for a statistical conclusion. (+info)Hemifacial spasm following a blow to the mandible causing blunt injury to the peripheral facial nerve. (4/21)
A 40-year-old male presented with hemifacial spasm manifesting as paroxysmal spontaneous twitches in the left peribuccal region persisting for 3 months. The symptoms began 7 days after an accident, when a signboard hit his left mandibular angle. Physical examination showed no trauma-related change in his face, and no neurological abnormality except for the twitches. Magnetic resonance imaging also showed no abnormalities of the facial nerve and adjacent regions. Electrophysiological studies showed synkinesis, so hemifacial spasm caused by peripheral facial nerve injury was suspect- ed. The symptoms subsided 4 months after the injury. Blunt injury to the facial nerve branches might cause hemifacial spasm. (+info)Loss of permanent mandibular lateral incisor and canine tooth buds through extraoral sinus: report of a case. (5/21)
Extraoral sinus tract may occur as a result of an inflammatory process associated with the necrotic pulp. Several non odontogenic disorders may also produce an extraoral sinus tract, the differential diagnosis of these clinical findings is of prime importance in providing appropriate clinical care. Presented here is a case report of 4 year old female child with extraoral sinus tract through which the tooth buds of mandibular permanent left lateral incisor and mandibular permanent left canine were lost. The extraoral sinus was due to mandibular left primary canine with class IX fracture (Ellis and Davey's classification). (+info)Orthognathic surgery for occlusal reconstruction of old malunited jaw fracture. (6/21)
Old malunited jaw fractures of nine patients who underwent orthognathic surgery for occlusal reconstruction were clinically evaluated. Early surgery on fractures of the jaw is the optimal treatment when due attention must be paid to occlusion. Since occlusal revision surgery subsequent to inaccurate diagnosis and inappropriate surgery is certainly very difficult and often unsuccessful, surgeons need to pay special attention to this situation. (+info)Defect repair in rat mandible with hydroxyapatite cement compared to small intestine submucosa. (7/21)
AIM: The aim of this study was to evaluate the bone formation in surgically created defects of rabbit mandibles by synthetic hydroxyapatite of calcium compared to small Intestine Submucosa. MATERIAL AND METHOD: 24 mice lineage Wisthar-Furth were used. A bony defect of 0,75 cm x 1,5 cm in mandibular ramus was accomplished in all animals. The hydroxyapatite implants were placed on the left hemimandiblein group I, small Intestine submucosa in group II, and the right served as control. The euthanasia was accomplished in the 40 degrees postoperative day, it was proceeded the macroscopic and histological analysis. RESULTS: medium length in millimeters of the hemimandibless in the hydroxyapatite group was of 3,75, in the small intestine submucosa 3,03 and the control group was of 2,63 (p: 0,022). Histomorphometry study revealed new bone grown in 76,64% of the total area in hydroxyapatite group (p: 0,022). In Small Intestinal submucosa group new bone grown in 63,64% do total (p: 0,0022). DISCUSSION: satisfactory bone integration was observed of the synthetic hydroxyapatite in that experimental model. Small intestinal submucosa cause osteoinduction CONCLUSION: using hydroxyapatite of calcium resulted in formation of significantly larger volume fractions of new bone when compared to small intestinal submucosa group. (+info)Evaluation of different rotary devices on bone repair in rabbits. (8/21)
In oral surgery, the quality of bone repair may be influenced by several factors that can increase the morbidity of the procedure. The type of equipment used for ostectomy can directly affect bone healing. The aim of this study was to evaluate bone repair of mandible bone defects prepared in rabbits using three different rotary devices. Fifteen New Zealand rabbits were randomly assigned to 3 groups (n=5) according to type of rotary device used to create bone defects: I--pneumatic low-speed rotation engine, II--pneumatic high-speed rotation engine, and III--electric low-speed rotation engine. The anatomic pieces were surgically obtained after 2, 7 and 30 days and submitted to histological and morphometric analysis. The morphometric results were expressed as the total area of bone remodeling matrix using an image analysis system. Increases in the bone remodeling matrix were noticed with time along the course of the experiment. No statistically significant differences (p>0.05) were observed among the groups at the three sacrificing time points considering the total area of bone mineralized matrix, although the histological analysis showed a slightly advanced bone repair in group III compared to the other two groups. The findings of the present study suggest that the type of rotary device used in oral and maxillofacial surgery does not interfere with the bone repair process. (+info)Mandibular injuries refer to damages or traumas inflicted on the mandible, or lower jawbone, which may include fractures, dislocations, soft tissue wounds, or dental trauma, often resulting from various causes such as road accidents, sports mishaps, physical assaults, or falls.
Mandibular injuries refer to damages or traumas that affect the mandible, which is the lower part of the jawbone. These injuries can result from various causes, such as road accidents, physical assaults, sports-related impacts, or falls. Mandibular injuries may include fractures, dislocations, soft tissue damage, or dental injuries.
Symptoms of mandibular injuries might include pain, swelling, bruising, difficulty speaking, chewing, or opening the mouth wide, and in some cases, visible deformity or misalignment of the jaw. Depending on the severity and type of injury, treatment options may range from conservative management with pain control and soft diet to surgical intervention for fracture reduction and fixation. Immediate medical attention is crucial to ensure proper diagnosis, appropriate treatment, and prevention of potential complications.
"Wounds and injuries refer to physical traumas causing damage to living tissues, which may result from surgical procedures, accidents, violence, or specific disease processes, potentially leading to functional impairment, disfigurement, or life-threatening conditions."
A wound is a type of injury that occurs when the skin or other tissues are cut, pierced, torn, or otherwise broken. Wounds can be caused by a variety of factors, including accidents, violence, surgery, or certain medical conditions. There are several different types of wounds, including:
* Incisions: These are cuts that are made deliberately, often during surgery. They are usually straight and clean.
* Lacerations: These are tears in the skin or other tissues. They can be irregular and jagged.
* Abrasions: These occur when the top layer of skin is scraped off. They may look like a bruise or a scab.
* Punctures: These are wounds that are caused by sharp objects, such as needles or knives. They are usually small and deep.
* Avulsions: These occur when tissue is forcibly torn away from the body. They can be very serious and require immediate medical attention.
Injuries refer to any harm or damage to the body, including wounds. Injuries can range from minor scrapes and bruises to more severe injuries such as fractures, dislocations, and head trauma. It is important to seek medical attention for any injury that is causing significant pain, swelling, or bleeding, or if there is a suspected bone fracture or head injury.
In general, wounds and injuries should be cleaned and covered with a sterile bandage to prevent infection. Depending on the severity of the wound or injury, additional medical treatment may be necessary. This may include stitches for deep cuts, immobilization for broken bones, or surgery for more serious injuries. It is important to follow your healthcare provider's instructions carefully to ensure proper healing and to prevent complications.
"Brain injuries, also known as traumatic brain injuries (TBIs), refer to damages to the brain caused by an external force, often resulting in physical, cognitive, and psychological impairments."
A brain injury is defined as damage to the brain that occurs following an external force or trauma, such as a blow to the head, a fall, or a motor vehicle accident. Brain injuries can also result from internal conditions, such as lack of oxygen or a stroke. There are two main types of brain injuries: traumatic and acquired.
Traumatic brain injury (TBI) is caused by an external force that results in the brain moving within the skull or the skull being fractured. Mild TBIs may result in temporary symptoms such as headaches, confusion, and memory loss, while severe TBIs can cause long-term complications, including physical, cognitive, and emotional impairments.
Acquired brain injury (ABI) is any injury to the brain that occurs after birth and is not hereditary, congenital, or degenerative. ABIs are often caused by medical conditions such as strokes, tumors, anoxia (lack of oxygen), or infections.
Both TBIs and ABIs can range from mild to severe and may result in a variety of physical, cognitive, and emotional symptoms that can impact a person's ability to perform daily activities and function independently. Treatment for brain injuries typically involves a multidisciplinary approach, including medical management, rehabilitation, and supportive care.
Radiation Oncology is a branch of medical science that deals with the application and management of ionizing radiation in the treatment, alleviation, and prevention of cancerous diseases.
Radiation oncology is a branch of medicine that uses ionizing radiation in the treatment and management of cancer. The goal of radiation therapy, which is the primary treatment modality in radiation oncology, is to destroy cancer cells or inhibit their growth while minimizing damage to normal tissues. This is achieved through the use of high-energy radiation beams, such as X-rays, gamma rays, and charged particles, that are directed at the tumor site with precision. Radiation oncologists work in interdisciplinary teams with other healthcare professionals, including medical physicists, dosimetrists, and radiation therapists, to plan and deliver effective radiation treatments for cancer patients.
Hypochondriasis is a psychological disorder characterized by the persistent and unwarranted belief that one has a serious illness, despite having no or only mild symptoms and receiving negative test results from physical examinations.
Hypochondriasis is a psychological disorder where an individual has an unrealistic and persistent fear or belief that they have one or more serious medical conditions, based on the interpretation of bodily symptoms. These fears or beliefs are not alleviated by appropriate medical evaluation and reassurance. The person may be extremely anxious about their health, repeatedly check their body for signs of illness, and seek medical help frequently. However, it's important to note that this term is no longer used in the current diagnostic manuals like DSM-5 or ICD-10. Instead, similar symptoms are often encompassed under Illness Anxiety Disorder.
Tooth extraction is a dental procedure involving the removal of a tooth from its socket in the alveolar bone, typically performed due to severe tooth decay, infection, or trauma that cannot be restored or preserved.
Tooth extraction is a dental procedure in which a tooth that is damaged or poses a threat to oral health is removed from its socket in the jawbone. This may be necessary due to various reasons such as severe tooth decay, gum disease, fractured teeth, crowded teeth, or for orthodontic treatment purposes. The procedure is performed by a dentist or an oral surgeon, under local anesthesia to numb the area around the tooth, ensuring minimal discomfort during the extraction process.
"Radiation injuries refer to the damages caused to living tissues by exposure to ionizing radiation, resulting in cellular dysfunction or death, which can lead to acute and chronic symptoms depending on the intensity and duration of exposure."
Radiation injuries refer to the damages that occur to living tissues as a result of exposure to ionizing radiation. These injuries can be acute, occurring soon after exposure to high levels of radiation, or chronic, developing over a longer period after exposure to lower levels of radiation. The severity and type of injury depend on the dose and duration of exposure, as well as the specific tissues affected.
Acute radiation syndrome (ARS), also known as radiation sickness, is the most severe form of acute radiation injury. It can cause symptoms such as nausea, vomiting, diarrhea, fatigue, fever, and skin burns. In more severe cases, it can lead to neurological damage, hemorrhage, infection, and death.
Chronic radiation injuries, on the other hand, may not appear until months or even years after exposure. They can cause a range of symptoms, including fatigue, weakness, skin changes, cataracts, reduced fertility, and an increased risk of cancer.
Radiation injuries can be treated with supportive care, such as fluids and electrolytes replacement, antibiotics, wound care, and blood transfusions. In some cases, surgery may be necessary to remove damaged tissue or control bleeding. Prevention is the best approach to radiation injuries, which includes limiting exposure through proper protective measures and monitoring radiation levels in the environment.
Radiotherapy, also known as radiation therapy, is a medical treatment using ionizing radiation to manage diseases, primarily cancer, by killing cells or inhibiting their ability to multiply, while minimizing harm to normal tissues.
Radiotherapy, also known as radiation therapy, is a medical treatment that uses ionizing radiation to kill cancer cells, shrink tumors, and prevent the growth and spread of cancer. The radiation can be delivered externally using machines or internally via radioactive substances placed in or near the tumor. Radiotherapy works by damaging the DNA of cancer cells, which prevents them from dividing and growing. Normal cells are also affected by radiation, but they have a greater ability to repair themselves compared to cancer cells. The goal of radiotherapy is to destroy as many cancer cells as possible while minimizing damage to healthy tissue.
'Radiation injuries, experimental' refers to intentional exposure of living organisms or tissues to controlled levels of ionizing radiation in a laboratory setting to study the biological effects, cellular responses, and medical countermeasures against radiation-induced damage.
'Radiation injuries, experimental' is not a widely recognized medical term. However, in the field of radiation biology and medicine, it may refer to the study and understanding of radiation-induced damage using various experimental models (e.g., cell cultures, animal models) before applying this knowledge to human health situations. These experiments aim to investigate the effects of ionizing radiation on living organisms' biological processes, tissue responses, and potential therapeutic interventions. The findings from these studies contribute to the development of medical countermeasures, diagnostic tools, and treatment strategies for accidental or intentional radiation exposures in humans.
'Dose fractionation' in medical terms refers to the practice of dividing the total dose of radiation therapy into smaller amounts given over a number of treatment sessions, allowing normal tissues to recover while maintaining tumor control.
Dose fractionation is a medical term that refers to the practice of dividing the total dose of radiation therapy or chemotherapy into smaller doses, which are given over a longer period. This approach allows for the delivery of a higher total dose of treatment while minimizing damage to healthy tissues and reducing side effects.
In radiation therapy, fractionation is used to target cancer cells while sparing surrounding normal tissues. By delivering smaller doses of radiation over several treatments, healthy tissue has time to recover between treatments, reducing the risk of complications. The number and size of fractions can vary depending on the type and location of the tumor, as well as other factors such as the patient's overall health.
Similarly, in chemotherapy, dose fractionation is used to maximize the effectiveness of the treatment while minimizing toxicity. By administering smaller doses of chemotherapy over time, the body has a chance to recover between treatments, reducing side effects and allowing for higher total doses to be given. The schedule and duration of chemotherapy fractionation may vary depending on the type of drug used, the type and stage of cancer, and other factors.
Overall, dose fractionation is an important technique in both radiation therapy and chemotherapy that allows for more effective treatment while minimizing harm to healthy tissues.
