What is Laparoscopic Cholecystectomy?
What is Laparoscopic Cholecystectomy? Surgeon 38 Views • 2 years ago

Cholecystectomy means removal of the gallbladder. The most common reasons
your doctor might recommend a cholecystectomy are biliary colic, cholecystitis,
choledocolithiasis, or gallstone pancreatitis. Biliary colic, also known as symptomatic
cholelithiasis, is caused by gallstones, which are hardened deposits of bile. Gallstones are
common in the general population, and gallstones alone are not a reason for gallbladder
removal if they do not cause symptoms. However, sometimes gallstones can get caught at the
neck of the gallbladder, causing pain when the gallbladder contracts against them trying to
release its bile, especially after a fatty meal. With biliary colic, the pain typically resolves within
an hour or so. Occasionally, a stone or some other blockage may prevent the gallbladder from
emptying over a long period of time, causing an increase in pressure and trapped fluid within the
gallbladder. This can cause inflammation and infection of the gallbladder, which we call
cholecystitis. Choledocholithiasis is when there are one or more stones in the bile ducts, which
can cause back up of bile into the liver, and depending on the location of the stones, could
cause pancreatitis, which is inflammation of the pancreas. Other reasons for gallbladder
removal, though less common, are gallbladder polyps and cancer. All of these are reasons for
gallbladder removal.

Burns Degrees Classification
Burns Degrees Classification Mohamed Ibrahim 9,807 Views • 2 years ago

What are the classifications of burns? Burns are classified as first-, second-, or third-degree, depending on how deep and severe they penetrate the skin's surface. First-degree (superficial) burns. First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example. Long-term tissue damage is rare and usually consists of an increase or decrease in the skin color. Second-degree (partial thickness) burns. Second-degree burns involve the epidermis and part of the dermis layer of skin. The burn site appears red, blistered, and may be swollen and painful. Third-degree (full thickness) burns. Third-degree burns destroy the epidermis and dermis and may go into the subcutaneous tissue. The burn site may appear white or charred Fourth degree burns. Fourth degree burns also damage the underlying bones, muscles, and tendons. There is no sensation in the area since the nerve endings are destroyed.

Diagnosis To determine the most appropriate treatment for your stroke, your emergency team needs to evaluate the type of stroke you're having and the areas of your brain affected by the stroke. They also need to rule out other possible causes of your symptoms, such as a brain tumor or a drug reaction. Your doctor may use several tests to determine your risk of stroke, including: Stroke consultation Stroke consultation Stroke consultation at Mayo Clinic Brain tissue damaged by stroke CT scan of brain tissue damaged by stroke Cerebral angiogram Cerebral angiogram Physical examination. Your doctor will ask you or a family member what symptoms you've been having, when they started and what you were doing when they began. Your doctor then will evaluate whether these symptoms are still present. Your doctor will want to know what medications you take and whether you have experienced any head injuries. You'll be asked about your personal and family history of heart disease, transient ischemic attack and stroke. Your doctor will check your blood pressure and use a stethoscope to listen to your heart and to listen for a whooshing sound (bruit) over your neck (carotid) arteries, which may indicate atherosclerosis. Your doctor may also use an ophthalmoscope to check for signs of tiny cholesterol crystals or clots in the blood vessels at the back of your eyes. Blood tests. You may have several blood tests, which tell your care team how fast your blood clots, whether your blood sugar is abnormally high or low, whether critical blood chemicals are out of balance, or whether you may have an infection. Managing your blood's clotting time and levels of sugar and other key chemicals will be part of your stroke care. Computerized tomography (CT) scan. A CT scan uses a series of X-rays to create a detailed image of your brain. A CT scan can show a hemorrhage, tumor, stroke and other conditions. Doctors may inject a dye into your bloodstream to view your blood vessels in your neck and brain in greater detail (computerized tomography angiography). There are different types of CT scans that your doctor may use depending on your situation. Magnetic resonance imaging (MRI). An MRI uses powerful radio waves and magnets to create a detailed view of your brain. An MRI can detect brain tissue damaged by an ischemic stroke and brain hemorrhages. Your doctor may inject a dye into a blood vessel to view the arteries and veins and highlight blood flow (magnetic resonance angiography, or magnetic resonance venography). Carotid ultrasound. In this test, sound waves create detailed images of the inside of the carotid arteries in your neck. This test shows buildup of fatty deposits (plaques) and blood flow in your carotid arteries. Cerebral angiogram. In this test, your doctor inserts a thin, flexible tube (catheter) through a small incision, usually in your groin, and guides it through your major arteries and into your carotid or vertebral artery. Then your doctor injects a dye into your blood vessels to make them visible under X-ray imaging. This procedure gives a detailed view of arteries in your brain and neck. Echocardiogram. An echocardiogram uses sound waves to create detailed images of your heart. An echocardiogram can find a source of clots in your heart that may have traveled from your heart to your brain and caused your stroke. You may have a transesophageal echocardiogram. In this test, your doctor inserts a flexible tube with a small device (transducer) attached into your throat and down into the tube that connects the back of your mouth to your stomach (esophagus). Because your esophagus is directly behind your heart, a transesophageal echocardiogram can create clear, detailed ultrasound images of your heart and any blood clots. Treatment Emergency treatment for stroke depends on whether you're having an ischemic stroke blocking an artery — the most common kind — or a hemorrhagic stroke that involves bleeding into the brain. Ischemic stroke To treat an ischemic stroke, doctors must quickly restore blood flow to your brain. Emergency treatment with medications. Therapy with clot-busting drugs must start within 4.5 hours if they are given into the vein — and the sooner, the better. Quick treatment not only improves your chances of survival but also may reduce complications. You may be given: Intravenous injection of tissue plasminogen activator (tPA). This injection of recombinant tissue plasminogen activator (tPA), also called alteplase, is considered the gold standard treatment for ischemic stroke. An injection of tPA is usually given through a vein in the arm. This potent clot-busting drug ideally is given within three hours. In some instances, tPA can be given up to 4.5 hours after stroke symptoms begin. This drug restores blood flow by dissolving the blood clot causing your stroke, and it may help people who have had strokes recover more fully. Your doctor will consider certain risks, such as potential bleeding in the brain, to determine if tPA is appropriate for you. Emergency endovascular procedures. Doctors sometimes treat ischemic strokes with procedures performed directly inside the blocked blood vessel. These procedures must be performed as soon as possible, depending on features of the blood clot: Medications delivered directly to the brain. Doctors may insert a long, thin tube (catheter) through an artery in your groin and thread it to your brain to deliver tPA directly into the area where the stroke is occurring. This is called intra-arterial thrombolysis. The time window for this treatment is somewhat longer than for intravenous tPA, but is still limited. Removing the clot with a stent retriever. Doctors may use a catheter to maneuver a device into the blocked blood vessel in your brain and trap and remove the clot. This procedure is particularly beneficial for people with large clots that can't be completely dissolved with tPA, though this procedure is often performed in combination with intravenous tPA. Several large and recent studies suggest that, depending on the location of the clot and other factors, endovascular therapy might be the most effective treatment. Endovascular therapy has been shown to significantly improve outcomes and reduce long-term disability after ischemic stroke. Other procedures. To decrease your risk of having another stroke or transient ischemic attack, your doctor may recommend a procedure to open up an artery that's narrowed by plaque. Doctors sometimes recommend the following procedures to prevent a stroke. Options will vary depending on your situation: Carotid endarterectomy. In a carotid endarterectomy, a surgeon removes plaques from arteries that run along each side of your neck to your brain (carotid arteries). In this procedure, your surgeon makes an incision along the front of your neck, opens your carotid artery and removes plaque that blocks the carotid artery. Your surgeon then repairs the artery with stitches or a patch made from a vein or artificial material (graft). The procedure may reduce your risk of ischemic stroke. However, a carotid endarterectomy also involves risks, especially for people with heart disease or other medical conditions. Angioplasty and stents. In an angioplasty, a surgeon usually accesses your carotid arteries through an artery in your groin. Here, your surgeon can gently and safely navigate to the carotid arteries in your neck. A balloon is then inflated to expand the narrowed artery. Then a stent can be inserted to support the opened artery. Hemorrhagic stroke Emergency treatment of hemorrhagic stroke focuses on controlling your bleeding and reducing pressure in your brain. You might also need surgery to help reduce future risk. Emergency measures. If you take warfarin (Coumadin, Jantoven) or anti-platelet drugs such as clopidogrel (Plavix) to prevent blood clots, you may be given drugs or transfusions of blood products to counteract the blood thinners' effects. You may also be given drugs to lower pressure in your brain (intracranial pressure), lower your blood pressure, prevent vasospasm or prevent seizures. Once the bleeding in your brain stops, treatment usually involves supportive medical care while your body absorbs the blood. Healing is similar to what happens while a bad bruise goes away. If the area of bleeding is large, your doctor may perform surgery to remove the blood and relieve pressure on your brain. Surgical blood vessel repair. Surgery may be used to repair blood vessel abnormalities associated with hemorrhagic strokes. Your doctor may recommend one of these procedures after a stroke or if an aneurysm or arteriovenous malformation (AVM) or other type of vascular malformation caused your hemorrhagic stroke: Surgical clipping. A surgeon places a tiny clamp at the base of the aneurysm, to stop blood flow to it. This clamp can keep the aneurysm from bursting, or it can prevent re-bleeding of an aneurysm that has recently hemorrhaged. Coiling (endovascular embolization). A surgeon inserts a catheter into an artery in your groin and guides it to your brain using X-ray imaging. Tiny detachable coils are guided into the aneurysm (aneurysm coiling). The coils fill the aneurysm, which blocks blood flow into the aneurysm and causes the blood to clot. Surgical AVM removal. Surgeons may remove a smaller AVM if it's located in an accessible area of your brain, to eliminate the risk of rupture and lower the risk of hemorrhagic stroke. However, it's not always possible to remove an AVM if its removal would cause too large a reduction in brain function, or if it's large or located deep within your brain. Stereotactic radiosurgery. Using multiple beams of highly focused radiation, stereotactic radiosurgery is an advanced minimally invasive treatment used to repair vascular malformations. Stroke recovery and rehabilitation Brain hemisphere connections Brain hemisphere connections After emergency treatment, stroke care focuses on helping you recover as much function as possible and return to independent living. The impact of your stroke depends on the area of the brain involved and the amount of tissue damaged. If your stroke affected the right side of your brain, your movement and sensation on the left side of your body may be affected. If your stroke damaged the brain tissue on the left side of your brain, your movement and sensation on the right side of your body may be affected. Brain damage to the left side of your brain may cause speech and language disorders. In addition, if you've had a stroke, you may have problems with breathing, swallowing, balancing and vision. Most stroke survivors receive treatment in a rehabilitation program. Your doctor will recommend the most rigorous therapy program you can handle based on your age, overall health and degree of disability from your stroke. Your doctor will take into consideration your lifestyle, interests and priorities, and the availability of family members or other caregivers. Your rehabilitation program may begin before you leave the hospital. After discharge, you might continue your program in a rehabilitation unit of the same hospital, another rehabilitation unit or skilled nursing facility, an outpatient unit, or your home. Every person's stroke recovery is different. Depending on your condition, your treatment team may include: Doctor trained in brain conditions (neurologist) Rehabilitation doctor (physiatrist) Nurse Dietitian Physical therapist Occupational therapist Recreational therapist Speech pathologist Social worker Case manager Psychologist or psychiatrist Chaplain Speech therapy session Speech therapy is often a part of stroke rehabilitation. Treatment outcomes One way to evaluate the care of patients diagnosed with stroke is to look at the percentage of patients receiving the timely and effective care measures that are appropriate. The goal is 100 percent. The graphs below display the percentage of eligible Mayo Clinic patients diagnosed with stroke receiving all of the appropriate care measures.

First Aid for Burns
First Aid for Burns Mohamed Ibrahim 10,662 Views • 2 years ago

A burn is tissue damage that results from scalding, overexposure to the sun or other radiation, contact with flames, chemicals or electricity, or smoke inhalation. Is it a major or minor burn? Call 911 or seek immediate care for major burns, which: Are deep Cause the skin to be dry and leathery May appear charred or have patches of white, brown or black Are larger than 3 inches (about 8 centimeters) in diameter or cover the hands, feet, face, groin, buttocks or a major joint A minor burn that doesn't require emergency care may involve: Superficial redness similar to a sunburn Pain Blisters An area no larger than 3 inches (about 8 centimeters) in diameter Treating major burns Until emergency help arrives: Protect the burned person from further harm. If you can do so safely, make sure the person you're helping is not in contact with the source of the burn. For electrical burns, make sure the power source is off before you approach the burned person. Make certain that the person burned is breathing. If needed, begin rescue breathing if you know how. Remove jewelry, belts and other restrictive items, especially from around burned areas and the neck. Burned areas swell rapidly. Cover the area of the burn. Use a cool, moist bandage or a clean cloth. Don't immerse large severe burns in water. Doing so could cause a serious loss of body heat (hypothermia). Elevate the burned area. Raise the wound above heart level, if possible. Watch for signs of shock. Signs and symptoms include fainting, pale complexion or breathing in a notably shallow fashion. Treating minor burns For minor burns: Cool the burn. Hold the burned area under cool (not cold) running water or apply a cool, wet compress until the pain eases. Remove rings or other tight items from the burned area. Try to do this quickly and gently, before the area swells. Don't break blisters. Fluid-filled blisters protect against infection. If a blister breaks, clean the area with water (mild soap is optional). Apply an antibiotic ointment. But if a rash appears, stop using the ointment. Apply lotion. Once a burn is completely cooled, apply a lotion, such as one that contains aloe vera or a moisturizer. This helps prevent drying and provides relief. Bandage the burn. Cover the burn with a sterile gauze bandage (not fluffy cotton). Wrap it loosely to avoid putting pressure on burned skin. Bandaging keeps air off the area, reduces pain and protects blistered skin. If needed, take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or acetaminophen (Tylenol, others).
