Cerebral edema is a life threatening homeostatic imbalance that may be caused by many things and can be treated if the diagnosis, recognition and management is timely. (ScienceDirect: Cerebral Edema) There are three categories of cerebral edema: vasogenic, cytotoxic and interstitial. Vasogenic edema happens when there is increased permeability of the blood brain barrier. Some of the most common vasogenic causes of edema include: brain tumors/abscesses, lead toxicity, stroke, diabetic ketoacidosis and hypercapnia.
Common causes of this type of hemorrhage are hypertension, trauma, and the use of blood thinners. Subarachnoid hemorrhage occurs when an artery within the surface of the brain bursts and spills in the space between the surface of the brain and skull. The leakage is most commonly caused by an aneurysm. A transient ischemic attack is also known as TIA or “mini stroke”.
Particularly, SDC is an epithelial tumor of high malignancy with formation of relatively large cell aggregates resembling distended salivary ducts. The neoplastic epithelium shows a combination of cribriform, looping and solid growth patterns, often with central necrosis, both in the primary lesion and the lymph node metastases. This extremely rare carcinoma looks like comedocarcinoma of the breast. The most important histologic attribute of this neoplasm is its similarity to ductal carcinoma of the breast. According to WHO annual incidence of all salivary gland tumors varies about
ABSTRACT Odontogenic keratocyst is the common cyst of odontogenic origin, which draws the attention because of its peculiarity. Now the lesion is renamed as Keratocystic odontogenic tumour (KCOT) because of its neoplastic nature and its tendency to recur. KCOT occurs most commonly in the mandibular ramus area. Maxillary anterior region is a rare site of occurrence. We present a rare case of maxillary KCOT with its clinical features, radiographic and histopathological and surgical management.
Marfan syndrome is not the only genetic disorder that affects connective tissue and has conditions including Thoracic Aortic Aneurysm. Marfan syndrome is a genetic disorder that messes with the connective tissue throughout the body (Marfan Foundation) and was discovered by Antoine Marfan in France back in 1896 (KidsHealth). Features of this genetic disorder are mostly found in the heart, blood vessels, bones, joints, and eyes. (Marfan Foundation) But it affects each person differently.
Symptoms may include dizziness, nausea and confusion. Although the loss of consciousness is possible, it is usually brief. The diagnosis of mild brain injury such as a concussion, usually made based on symptoms and a CT scan, which is used to rule out more serious injuries. The treatment is often not necessary.
If brain transplants were possible in the future, the identity of the person may change and be more like the identity of the donor of the brain.  This is because it is unlike a normal transplant, such as a transplanted heart, but the brain is where memory, identity and personality are all stored, so the outcomes may be
The nervous system is the body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) are made of nerves. The brain is made of three main parts which are the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus. The midbrain consists of the tectum and tegmentum.
The amelanotic form of metastatic melanoma of the skin is a less common presentation and appears as a skin-colored, pink or red skin lesion. The three types of melanoma include ocular, cutaneous, and mucosal malignant melanoma. All of these subtypes have the potential to spread to the skin with advanced disease. However, cutaneous melanoma is the most common source of skin metastases of the three types. Melanoma skin metastases tend to occur on the chest, back, and extremities of men and on the lower extremities in
Let me start off by explaining what MS is. Multiple Sclerosis is when, for reasons scientists are not yet sure of, a person’s immune system attacks the myelin that covers and protects the spinal cord and nerve fibers in your brain. After the myelin is damaged, the nerve fibers then are attacked by the immune system as well. This causes nerve damage, fatigue, vision loss, poor balance, and more unpleasant side effects. Multiple Sclerosis itself isn’t necessarily the cause of death, however, it 's the complications of MS that take a great toll on one’s health.
The brain is the most complex organ in our body. It serves as the command center of the human nervous system. The brain is composed of different parts and functions that are dependent upon each other. The brain consists of two distinct sides: the right and left cerebral hemispheres. The side of the brain that endures damage will impact the function on the opposite side of the body and impairs mental capabilities.
