Smallpox disease is a serious, highly contagious, and often life-threatening infection marked by a rash of round pox (blisters) on the face, arms, and legs. It is caused by the Variola virus. The last case of smallpox in the United States was in 1949.

Hepatitis E
Hepatitis E samer kareem 2,274 Views • 3 years ago

The hepatitis E virus, responsible for major epidemics of viral hepatitis in subtropical and tropical countries, was cloned only 7 years ago.1 Hepatitis E was found to belong to the family of Caliciviridae, which includes the Norwalk virus—a common cause of gastroenteritis in humans—and consists of a single, plus-strand RNA genome of approximately 7.2 kb without an envelope (Fig. 1). The virus contains at least three open reading frames encoding viral proteins against which antibodies are made on exposure. These antibodies, especially those against the capsid protein derived from the second open reading frame2 and a protein of unknown function derived from the third open reading frame, are detected by currently available serologic assays. Retrospective studies on stored sera of past epidemics of viral hepatitis in Mexico, Africa, Afghanistan, Pakistan, India, Bangladesh, Burma, Nepal, and Borneo have revealed that all were caused by strains of hepatitis E. In addition, hepatitis E was found to be responsible for the hepatitis epidemic in the southern part of Xinjiang, China, in which 120,000 persons became infected between September 1986 and April 1988.3 Hepatitis E predominantly affects young adults (15 to 40 years old). The symptoms of hepatitis E are similar to those of hepatitis A. Frequently, a prodrome consisting of anorexia, nausea, low-grade fever, and right upper abdominal pain is present 3 to 7 days before jaundice develops. Aminotransferase levels peak (usually between 1,000 and 2,000 U/L) near the onset of symptoms; bilirubin levels (10 to 20 mg/dL) peak later. Jaundice usually resolves after 1 to 2 weeks. In about 10% of cases, the disease is fulminant—especially in pregnant women, among whom mortality rates as high as 20% due to hemorrhagic and thrombotic complications have been reported. No evidence has suggested that hepatitis E can cause chronic infection. Transmission is by the fecal-oral route, predominantly through fecally contaminated drinking water supplies. In addition, however, preliminary reports have suggested transmission of the hepatitis E virus through blood transfusions. Volunteer studies confirmed the presence of the virus in serum and feces before and during clinical disease.4 The virus is shed into feces approximately 1 week before symptoms develop. The incubation period varies from 2 to 9 weeks (mean duration, approximately 45 days). Until now, a few reports had described symptomatic hepatitis E acquired in Europe;5, 6 all patients with symptomatic hepatitis E in the United States were travelers returning from Mexico, Africa, or the Far East, in whom hepatitis E developed after their return home.7 In this issue of the Mayo Clinic Proceedings (pages 1133 to 1136), Kwo and associates describe a case of hepatitis E in a man who had not left the United States during the previous 10 years. Specific serologic tests for hepatitis E virus IgG (enzyme immunoassays and a fluorescent antibody blocking assay) and IgM8 (US strain-specific enzyme-linked immunosorbent assay with use of synthetic polypeptides deduced from the viral genome, as shown in Figure 1), developed at Abbott Laboratories (IgG and IgM) as well as at the Centers for Disease Control and Prevention (IgG), were used to prove that the patient indeed had acute hepatitis E. Researchers at Abbott Laboratories have prepared a report that describes most of the viral genome in this patient (Fig. I).8 Their results are interesting because this strain from the United States differs considerably from hepatitis E strains isolated in Mexico, Burma, Pakistan, or China. Furthermore, the sequence of the US strain is highly homologous (98% and 94% homology at the amino acid level to the second and third open reading frames, respectively) to a recently isolated hepatitis E strain from American swine.9 This finding suggests that, in the United States, hepatitis E is a zoonosis with the swine population as one of its hosts. This relationship would confirm earlier studies in Asia, where swine were also found to carry variants of the hepatitis E virus.10 Why are these two recent discoveries important for medicine in the United States? First, other sporadic, locally acquired cases of acute hepatitis may be caused by hepatitis E. Second, these back-to-back discoveries strongly suggest that a common natural host for hepatitis E is present in countries with more moderate climates. Because swine do not seem to experience any symptoms associated with infection and because symptoms in humans can be minor or absent, we now may also have an explanation for the 1 to 2% of positive hepatitis E serologic results in blood donors in the United States,11 Netherlands,12 and Italy,6 countries with large swine staples. Clearly, more research needs to be done to confirm this hypothesis. Third, in countries with more moderate climates, hepatitis E may often result in a subclinical infection. Is this variation in manifestation due to less virulent strains, and do sequence variations determine virulence? Fourth, swine may be used as an animal model for study of the disease as well as vaccine development.

heart failure
heart failure samer kareem 2,184 Views • 3 years ago

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life. One way to prevent heart failure is to control conditions that cause heart failure, such as coronary artery disease, high blood pressure, diabetes or obesity.

Coronary Stent Procedure
Coronary Stent Procedure samer kareem 2,237 Views • 3 years ago

Before the angioplasty procedure begins, you will receive some pain medicine. You may also be given medicine that relaxes you, and blood thinning medicines to prevent a blood clot from forming. You will lie on a padded table. Your doctor will insert a flexible tube (catheter) through a surgical cut into an artery. Sometimes the catheter will be placed in your arm or wrist, or in your upper leg or groin area. You will be awake during the procedure. The doctor will use live x-ray pictures to carefully guide the catheter up into your heart and arteries. Dye will be injected into your body to highlight blood flow through the arteries. This helps the doctor see any blockages in the blood vessels that lead to your heart. A guide wire is moved into and across the blockage. A balloon catheter is pushed over the guide wire and into the blockage. The balloon on the end is blown up (inflated). This opens the blocked vessel and restores proper blood flow to the heart. A wire mesh tube (stent) may then be placed in this blocked area. The stent is inserted along with the balloon catheter. It expands when the balloon is inflated. The stent is left there to help keep the artery open

Myocardial Infarction
Myocardial Infarction samer kareem 8,247 Views • 3 years ago

Myocardial infarction (MI), commonly known as a heart attack, is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Clinically, MI is a syndrome that can be recognized by a set of symptoms, chest pain being the hallmark of these symptoms in most cases, supported by biochemical laboratory changes, electrocardiographic (ECG) changes, or findings on imaging modalities able to detect myocardial injury and necrosis. According to the third universal definition of MI, implemented by a joint task force from the European Society of Cardiology (ESC), American College of Cardiology (ACC) Foundation, American Heart Association (AHA), and the World Heart Federation (WHF), MI is diagnosed when either of the following two criteria are met

Barbed Suture Technology in Plastic Surgery
Barbed Suture Technology in Plastic Surgery samer kareem 3,990 Views • 3 years ago

Barbed sutures first received US Food and Drug Administration approval for soft tissue approximation in 2005 and early adopters readily embraced this device to develop new techniques. It has become apparent that the advantages are more than just "skin deep." Superficial and deep fascia, cartilage, tendon, joint capsule, and fibrous periprosthetic capsules can also be manipulated. Barbed sutures have revolutionized our approach to facial rejuvenation and body contouring by enhancing our ability to quilt and powerfully lift tissue. The elimination of surgical drains and shorter surgical times has made this a true boon for plastic surgeons as well as many other surgical specialists. This article summarizes some of the current and evolving applications of this exciting new tool.

Dieta Alcalina Recetas, Listado De Alimentos Alcalinos, Que Es El Agua Alcalina, Menu Para Adelgazar-- http://dieta-alcalina-alimentos.good-info.co -- Entendiendo los Efectos del nivel de pH en el cuerpo El nivel de pH en el cuerpo tiene la habilidad de afectar cada célula del cuerpo. Cuando la sangre tiene un pH alcalino en vez de un pH ácido, ocurre un efecto positivo en cada función corporal del sistema. El cerebro, el sistema circulatorio, los nervios, los músculos, el sistema respiratorio, el sistema digestivo y reproductivo se pueden beneficiar de un nivel adecuado de pH. Por otro lado, cuando el pH del cuerpo es muy ácido, es susceptible a muchas enfermedades y problemas. Ganancia de peso, enfermedades del corazón, envejecimiento prematuro, fatiga, problemas nerviosos, alergias, enfermedades musculares y cáncer son las más probables a ocurrir cuando el pH del cuerpo no está al nivel óptimo. Ya que todos estos problemas son más probables a ocurrir cuando el pH del cuerpo está muy ácido, tiene sentido consumir una dieta rica en alimentos alcalinos. El objetivo principal es usualmente comer aproximadamente entre 75-80% de alimentos alcalinos junto con solamente entre 20-25% de alimentos ácidos. Si se mantiene este nivel en la dieta, el resultado final es un nivel de pH bajo en el cuerpo, el que se requiere para una salud óptima. Descubre como la dieta alcalina funciona & por qué los alimentos alcalinos son altamente recomendados para tu salud. Haz clic aquí http://dieta-alcalina-alimentos.good-info.co

chronic obstructive pulmonary disease
chronic obstructive pulmonary disease samer kareem 2,256 Views • 3 years ago

Pathologic changes in chronic obstructive pulmonary disease (COPD) occur in the large (central) airways, the small (peripheral) bronchioles, and the lung parenchyma. Most cases of COPD are the result of exposure to noxious stimuli, most often cigarette smoke. The normal inflammatory response is amplified in persons prone to COPD development. The pathogenic mechanisms are not clear but are most likely diverse. Increased numbers of activated polymorphonuclear leukocytes and macrophages release elastases in a manner that cannot be counteracted effectively by antiproteases, resulting in lung destruction. The primary offender has been found to be human leukocyte elastase, with synergistic roles suggested for proteinase-3 and macrophage-derived matrix metalloproteinases (MMPs), cysteine proteinases, and a plasminogen activator. Additionally, increased oxidative stress caused by free radicals in cigarette smoke, the oxidants released by phagocytes, and polymorphonuclear leukocytes all may lead to apoptosis or necrosis of exposed cells. Accelerated aging and autoimmune mechanisms have also been proposed as having roles in the pathogenesis of COPD.[5, 6] Cigarette smoke causes neutrophil influx, which is required for the secretion of MMPs; this suggests, therefore, that neutrophils and macrophages are required for the development of emphysema. Studies have also shown that in addition to macrophages, T lymphocytes, particularly CD8+, play an important role in the pathogenesis of smoking-induced airflow limitation. To support the inflammation hypothesis further, a stepwise increase in alveolar inflammation has been found in surgical specimens from patients without COPD versus patients with mild or severe emphysema. Indeed, mounting evidence supports the concept that dysregulation of apoptosis and defective clearance of apoptotic cells by macrophages play a prominent role in airway inflammation, particularly in emphysema.[7] Azithromycin (Zithromax) has been shown to improve this macrophage clearance function, providing a possible future treatment modality.[8] In patients with stable COPD without known cardiovascular disease, there is a high prevalence of microalbuminuria, which is associated with hypoxemia independent of other risk factors.[9] Chronic bronchitis Mucous gland hyperplasia (as seen in the images below) is the histologic hallmark of chronic bronchitis. Airway structural changes include atrophy, focal squamous metaplasia, ciliary abnormalities, variable amounts of airway smooth muscle hyperplasia, inflammation, and bronchial wall thickening.

Brazilian Butt Lift
Brazilian Butt Lift samer kareem 4,180 Views • 3 years ago

A Brazilian butt lift (BBL) uses a person's own fat to enhance the size and shape of the buttocks. A plastic surgeon first performs liposuction to remove fat from other areas of the body (often the stomach, hips, and thighs), then injects that fat into the backside. Additional liposuction can be done around the butt to improve the appearance of lift and contour.
