Racoon Eyes
Raccoon eyes, also known as panda eyes or periorbital ecchymosis, is a sign of basal skull fracture or subgaleal hematoma, a craniotomy that ruptured the meninges, or (rarely) certain cancers. Bilateral hemorrhage occurs when damage at the time of a facial fracture tears the meninges and causes the venous sinuses to bleed into the arachnoid villi and the cranial sinuses. In lay terms, blood from skull fracture seeps into the soft tissue around the eyes. Raccoon eyes may be accompanied by Battle's sign, an ecchymosis behind the ear. These signs may be the only sign of a skull fracture, as it may not show on an X-ray. They normally appear between 48 and 72 hours (2-3 days) after the injury. It is recommended that the patient not blow their nose, cough vigorously, or strain, to prevent further tearing of the meninges. Raccoon eyes may be bilateral or unilateral. If unilateral, it is highly suggestive of basilar skull fracture, with a positive predictive value of 85%. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSF Leak
A cerebrospinal fluid leak (CSF leak or CSFL) is a medical condition where the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord leaks out of one or more holes or tears in the dura mater. A CSF leak is classed as either spontaneous (primary), having no known cause (sCSF leak), or nonspontaneous (secondary) where it is attributed to an underlying condition. Causes of a primary CSF leak are those of Major trauma, trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. A lumbar puncture can give the symptom of a post-dural-puncture headache. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. A spinal CSF leak can be caused by one or more meninges, meningeal diverticulum, diverticula or CSF-venous fistulas not associated with an epidural space, epidural leak. A spo ...

Basilar Skull Fracture
A basilar skull fracture is a bone fracture, break of a bone in the base of skull, base of the skull. Symptoms may include Battle sign, bruising behind the ears, periorbital ecchymosis, bruising around the eyes, or hemotympanum, blood behind the ear drum. A Cerebrospinal fluid leak, cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in rhinorrhea, fluid leaking from the nose or otorrhea, ear. Meningitis occurs in about 14% of cases. Other complications include injuries to the cranial nerves or blood vessels. A basilar skull fracture typically requires a significant degree of trauma to occur. It is defined as a fracture of one or more of the temporal bone, temporal, occipital bone, occipital, sphenoid bone, sphenoid, frontal bone, frontal or ethmoid bone. Basilar skull fractures are divided into anterior fossa, middle fossa and Posterior cranial fossa, posterior fossa fractures. Facial fractures often also occur. Diagnosis is typically by CT scan.

Periorbital Conditions
The periorbita is the area around the orbit. Sometimes it refers specifically to the layer of tissue surrounding the orbit that consists of periosteum. However, it may refer to anything that is around the orbit, such as in periorbital cellulitis Periorbital cellulitis, or preseptal cellulitis, is an inflammation and infection of the eyelid and portions of skin around the eye anterior to the orbital septum. It may be caused by breaks in the skin around the eye, and subsequent spread to the .... References {{Authority control Tissues (biology) Human eye anatomy ...

Periorbital Puffiness
Periorbital puffiness, also known as puffy eyes, or swelling around the eyes, is the appearance of swelling in the tissues around the eyes, called the orbits. It is almost exclusively caused by fluid buildup around the eyes, or periorbital edema. Minor puffiness usually detectable below the eyes only is often called eye bags. Such transient puffiness is distinct from the age related and gradual increase in the size of the fat pad lying below the lower eyelids (suborbicularis oculi fat) which can also be colloquially referred to as eye bags. Causes While some degree of puffiness may be normal for a given individual, factors such as age and fatigue may make the swelling more prominent. The periorbital tissues are most noticeably swollen immediately after waking, perhaps due to the gravitational redistribution of fluid in the horizontal position. Eye puffiness may also be caused by: *Normal aging – As a person grows older, the skin around the eyes becomes thinner and may swell or ...

Periorbital Dark Circles
Periorbital dark circles (including dark circles of the lower eyelid) are dark blemishes around the eyes. There are many causes of this symptom, including heredity and bruising. Causes Anatomical factors Bony structure and prominence of the orbicularis oculi muscle can contribute to infraorbital dark circles. Skin in the lower eyelid is very thin which accentuates subdermal features. Allergies, asthma, and eczema Any condition that causes the eyes to itch can contribute to darker circles due to rubbing or scratching the skin around them. Hay fever sufferers in particular will notice under-eye "smudges" during the height of the allergy season. Atopy can lead to frequent rubbing of the eyes, leading to local inflammation and increased pigmentation. Also, dark circles from allergies are caused by superficial venous congestion in the capillaries under the eyes. Medications Any medications that cause blood vessels to dilate can cause circles under the eyes to darken. The skin under ...

Medical
Medicine is the science and Praxis (process), practice of caring for patients, managing the Medical diagnosis, diagnosis, prognosis, Preventive medicine, prevention, therapy, treatment, Palliative care, palliation of their injury or disease, and Health promotion, promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention (medical), prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, medical genetics, genetics, and medical technology to diagnosis (medical), diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, splint (medicine), external splints and traction, medical devices, biologic medical product, biologics, and Radiation (medicine), ionizing radiation, amongst others.

Surgical
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance ( cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require a surgi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinoplasty
Rhinoplasty (, nose + , to shape), commonly called nose job, medically called nasal reconstruction, is a plastic surgery procedure for altering and reconstructing the human nose, nose. There are two types of plastic surgery used – plastic surgery#reconstructive surgery, reconstructive surgery that restores the form and functions of the nose and Plastic surgery#Cosmetic surgery procedures, cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injury, injuries caused by various Trauma (medicine), traumas including blunt trauma, blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, Respiratory disease, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a nasal septum deviation, devi ...

Multiple Myeloma
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibody, antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, anemia, Kidney failure, renal insufficiency, and infections may occur. Complications may include hypercalcemia and amyloidosis. The cause of multiple myeloma is unknown. Risk factors include obesity, radiation exposure, family history, age and certain chemicals. There is an increased risk of multiple myeloma in certain occupations. This is due to the occupational exposure to aromatic hydrocarbon solvents having a role in causation of multiple myeloma. Multiple myeloma is the result of a multi-step malignant transformation, and almost universally originates from the pre-malignant stage monoclonal gammopathy of undetermined significance (MGUS). As MGUS evolves into MM, another pre-stage of the disease is reached, known as Smouldering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaposi’s Sarcoma
Kaposi's sarcoma (KS) is a type of cancer that can form masses on the skin, in lymph nodes, in the mouth, or in other organs. The skin lesions are usually painless, purple and may be flat or raised. Lesions can occur singly, multiply in a limited area, or may be widespread. Depending on the sub-type of disease and level of immune suppression, KS may worsen either gradually or quickly. Except for classic KS where there is generally no immune suppression, KS is caused by a combination of immune suppression (such as due to HIV/AIDS) and infection by Human herpesvirus 8 (HHV8 – also called KS-associated herpesvirus (KSHV)). Classic, endemic, immunosuppression therapy-related (also known as iatrogenic), and epidemic (also known as AIDS-related) sub-types are all described. Classic KS tends to affect older men in regions where KSHV is highly prevalent (Mediterranean, Eastern Europe, Middle East), is usually slow-growing, and most often affects only the legs. Endemic KS is most comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amyloidosis
Amyloidosis is a group of diseases in which abnormal proteins, known as amyloid fibrils, build up in tissue. There are several non-specific and vague signs and symptoms associated with amyloidosis. These include fatigue, peripheral edema, weight loss, shortness of breath, palpitations, and Orthostatic hypotension, feeling faint with standing. In AL amyloidosis, specific indicators can include enlargement of the tongue and periorbital purpura. In wild-type ATTR amyloidosis, non-cardiac symptoms include: bilateral carpal tunnel syndrome, lumbar spinal stenosis, biceps tendon rupture, Small fiber peripheral neuropathy, small fiber neuropathy, and autonomic dysfunction. There are about 36 different types of amyloidosis, each due to a specific Proteopathy, protein misfolding. Within these 36 proteins, 19 are grouped into Organ-limited amyloidosis, localized forms, 14 are grouped as Systemic disease, systemic forms, and three proteins can identify as either. These proteins can become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
