Living with Lewy Body Dementia - Mayo Clinic
Living with Lewy Body Dementia - Mayo Clinic samer kareem 1,835 Views • 3 years ago

LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD. LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms. While it may take more than a year or two for enough symptoms to develop for a doctor to diagnose LBD, it is critical to pursue a formal diagnosis. Early diagnosis allows for important early treatment that may extend quality of life and independence. LBD is a multisystem disease and typically requires a comprehensive treatment approach. This approach involves a team of physicians from different specialties who collaborate to provide optimum treatment of each symptom without worsening other LBD symptoms. Many people with LBD enjoy significant improvement of their symptoms with a comprehensive approach to treatment, and some can have remarkably little change from year to year. Some people with LBD are extremely sensitive or may react negatively to certain medications used to treat Alzheimer’s or Parkinson’s in addition to certain over-the-counter medications.

Strep Throat to Rheumatic Heart Disease
Strep Throat to Rheumatic Heart Disease samer kareem 1,530 Views • 3 years ago

What causes rheumatic fever? Rheumatic fever is not an infection itself, but rather the result of an untreated strep infection. When your body senses the strep infection, it sends antibodies to fight it. Sometimes, these antibodies attack the tissues of your joints or heart instead. If the antibodies attack your heart, they can cause your heart valves to swell, which can lead to scarring of the valve "doors" (called leaflets or cusps). Who is at risk for rheumatic fever? Fewer than 0.3% of people who have strep throat also get rheumatic fever. Rheumatic fever is most common among children aged 5 to 15, but adults may have the condition as well. Doctors think that a weakened immune system may make some people more likely to get rheumatic fever. And, although antibiotic medicines have reduced the number of cases of rheumatic fever in developed countries, there are still thousands of reported cases. What are the symptoms of rheumatic fever and how is it diagnosed? Symptoms of rheumatic fever usually begin 1 to 6 weeks after you have had a strep infection. They are Fever Joint pain or swelling in your wrists, elbows, knees, or ankles Small bumps under the skin over your elbows or knees (called nodules) A raised, red rash on your chest, back, or stomach Stomach pain or feeling less hungry Weakness, shortness of breath, or feeling very tired Your doctor will begin by doing a throat culture to find out if you have a strep infection. Then, your doctor will use a stethoscope to listen to your heart. He or she will also look for nodules on your joints. Sometimes, blood tests, chest x-rays, or an electrocardiogram (ECG or EKG) may be needed for a more definite diagnosis. How is rheumatic fever treated? Rheumatic fever must be treated right away. If you have a sore throat that lasts longer than 3 days, or if you have a fever and headache along with your sore throat, you should see your doctor for a throat culture. Even if you do not have a sore throat but have a fever and a skin rash, this could also mean a strep infection, and you should get tested. Remember rheumatic fever can result from an untreated strep infection, so it is very important to treat the infection before it leads to a worse condition.

Knee Injection
Knee Injection samer kareem 3,123 Views • 3 years ago

When oral medications do not relieve knee pain, but you're not to the point of pursuing knee surgery, one of the following injections or procedures may help. Hyaluronic acid supplements – Although not technically medications, these substances are injected into knee joints to supplement naturally occurring hyaluronic acid. In healthy joints hyaluronic acid acts as a shock absorber and lubricant, allowing joints to move smoothly over each other. However, the acid appears to break down in people with osteoarthritis. Injecting it into a joint may lessen pain and inflammation. The injections are given weekly for three or five weeks, depending on the product (examples are Synvisc and Hyalgan). A small amount of joint fluid is removed first to make room for the hyaluronic acid. Corticosteroid Injections – Doctors sometimes inject corticosteroids directly into the knee joint for quick relief of pain and inflammation. Their benefits may last anywhere from a few days to more than six months. While the injections bring targeted relief to the joint and lack many of the side effects of oral corticosteroid medications, they are not without risks. Repeated knee injections may actually contribute to cartilage breakdown. For that reason your doctor will likely put a limit on the number of injections you can receive. Read a report from the British Medical Journal on corticosteroid injections for knee osteoarthritis. Arthrocentesis – Also called joint fluid aspiration, arthrocentesis is removal of joint fluid through a hollow needle inserted into the joint space of the knee. Although the purpose of removing joint fluid from the knee is usually so that it can be tested in the lab, removing excess fluid can also quickly ease pain and swelling. Often after withdrawing fluid, doctors use the same puncture site where the fluid was removed to inject a corticosteroid preparation and/or anesthetic into the knee joint to further relieve pain and inflammation.

Management and Treatment of COPD
Management and Treatment of COPD samer kareem 1,646 Views • 3 years ago

This Video COPD, or chronic obstructive pulmonary (PULL-mun-ary) disease, is a progressive disease that makes it hard to breathe. "Progressive" means the disease gets worse over time. COPD can cause coughing that produces large amounts of mucus (a slimy substance), wheezing, shortness of breath, chest tightness, and other symptoms. Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. Long-term exposure to other lung irritants—such as air pollution, chemical fumes, or dust—also may contribute to COPD.

More than 1 million Americans suffer a heart attack every year. Traditional symptoms—chest pain or pressure, cold sweat, extreme weakness—are well known. But there are more subtle signs you’re having or are about to have a heart attack that can be easy to miss. If you experience any of the following symptoms, see a doctor. Noticing heart attack signs early and getting prompt treatment can save your life.

Interventional Stroke
Interventional Stroke samer kareem 5,366 Views • 3 years ago

The management of acute ischemic stroke has advanced greatly over the past 2 decades. New interventions, including intravenous and endovascular treatment strategies, have evolved to recanalize arteries and salvage the ischemic brain. The evolution of interventional approaches to the treatment of acute stroke has been prompted by the limitations of intravenous therapy and intended to extend the treatment window, improve recanalization rates, and subsequently long-term clinical outcomes. The major techniques that have defined the current field of interventional acute stroke management and the relevant past and current data, and ongoing clinical trials on interventional stroke therapy will be reviewed. New issues, such as futile recanalization, and time to microcatheter, will also be discussed.

Subcuticular Suture
Subcuticular Suture samer kareem 18,772 Views • 3 years ago

The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.

Parkinson's part 1
Parkinson's part 1 samer kareem 6,144 Views • 3 years ago

Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson's disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease can't be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,319 Views • 3 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Laparoscopic Colectomy
Laparoscopic Colectomy samer kareem 6,177 Views • 3 years ago

On the day of your surgery, your health care team will take you to a preparation room. Your blood pressure and breathing will be monitored. You may receive an antibiotic medication through a vein in your arm. You will then be taken to an operating room and positioned on a table. You'll be given a general anesthesia medication to put you in a sleep-like state so that you won't be aware during your operation. The surgical team will then proceed with your colectomy. Colon surgery may be performed in two ways: Open colectomy. Open surgery involves making a longer incision in your abdomen to access your colon. Your surgeon uses surgical tools to free your colon from the surrounding tissue and cuts out either a portion of the colon or the entire colon. Laparoscopic colectomy. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Your surgeon passes a tiny video camera through one incision and special surgical tools through the other incisions. The surgeon watches a video screen in the operating room as the tools are used to free the colon from the surrounding tissue. The colon is then brought out through a small incision in your abdomen. This allows the surgeon to operate on the colon outside of your body. Once repairs are made to the colon, the surgeon reinserts the colon through the incision. The type of operation you undergo depends on your situation and your surgeon's expertise. Laparoscopic colectomy may reduce the pain and recovery time after surgery. But not everyone is a candidate for this procedure. Also, in some situations your operation may begin as a laparoscopic colectomy, but circumstances may force your surgical team to convert to an open colectomy. Once the colon has been repaired or removed, your surgeon will reconnect your digestive system to allow your body to expel waste. Options may include: Rejoining the remaining portions of your colon. The surgeon may stitch the remaining portions of your colon together, creating what is called an anastomosis. Stool then leaves your body as before. Connecting your intestine to an opening created in your abdomen. The surgeon may attach your colon (colostomy) or small intestine (ileostomy) to an opening created in your abdomen. This allows waste to leave your body through the opening (stoma). You may wear a bag on the outside of the stoma to collect stool. This can be permanent or temporary. Connecting your small intestine to your anus. After removing both the colon and the rectum (proctocolectomy), the surgeon may use a portion of your small intestine to create a pouch that is attached to your anus (ileoanal anastomosis). This allows you to expel waste normally, though you may have several watery bowel movements each day. As part of this procedure, you may undergo a temporary ileostomy.

AIDS Dementia:
AIDS Dementia: samer kareem 6,470 Views • 3 years ago

ADC was first identified early in the AIDS epidemic as a common and novel CNS syndrome.(4,5) The three components of the term, AIDS dementia complex embody central features of the condition. AIDS emphasizes its morbidity and poor prognosis, particularly when its severity is at stage 2 or greater (see Table 1), a severity comparable to other clinical AIDS-defining complications of HIV-1 infection. Dementia designates the acquired and persistent cognitive decline with preserved alertness that usually dominates the clinical presentation and determines its principal disability. Complex emphasizes that this disease not only impairs the intellect, but also concomitantly alters motor performance and, at times, behavior. This involvement of the nervous system beyond cognition is evidence of a wider involvement of the CNS than occurs in some other types of dementia such as Alzheimer's disease. Additionally, myelopathy may be an important, indeed predominating, aspect of ADC, and organic psychosis may also be a feature in a subset of patients (see Rheumatologic and Musculoskeletal Manifestations of HIV). These manifestations are therefore also encompassed within this term. By contrast, neither neuropathy nor functional psychiatric disturbance are included in ADC.
