Osteoporosis and How to prevent it
Osteoporosis and How to prevent it samer kareem 2,941 Views • 3 years ago

Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced. Osteoporosis occurs when the creation of new bone doesn't keep up with the removal of old bone. Osteoporosis affects men and women of all races. But white and Asian women — especially older women who are past menopause — are at highest risk. Medications, healthy diet and weight-bearing exercise can help prevent bone loss or strengthen already weak bones.

In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.

Claudication, which is defined as reproducible ischemic muscle pain, is one of the most common manifestations of peripheral arterial occlusive disease (PAOD) caused by atherosclerosis. Claudication occurs during physical activity and is relieved after a short rest. Pain develops because of inadequate blood flow. Examination of a patient with claudication should include a complete lower-extremity evaluation and pulse examination, including measuring segmental pressures. Attempt to palpate pulses from the abdominal aorta to the foot, with auscultation for bruits in the abdominal and pelvic regions. When palpable pulses are not present, a handheld Doppler device may be used to assess circulation.

Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,558 Views • 3 years ago

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

In rare cases, the uvula can swell enough to block your airway. Swelling of the throat is a life-threatening event. If this happens, seek immediate medical attention. What causes a swollen uvula? Causes Inflammation is your body’s response when it’s under attack. Triggers for inflammation include: environmental and lifestyle factors an infection trauma genetics Environmental and Lifestyle Factors The most common food allergies are peanuts tree nuts milk eggs wheat soy fish, including shellfish You could be having an allergic reaction to something you touched, swallowed, or breathed in. Some common allergens include: food irritants , such as dust, animal dander, or pollen medication exposure to chemicals or other toxic substances, including tobacco Infection You can get viral infections or bacterial infections. Examples of viral infections include: the common cold the flu mononucleosis chickenpox measles croup The most common bacterial infection is strep throat, which occurs due to Streptococcus pyogenes, which is a type of group A Streptococcus. If you have infected tonsils, or tonsillitis, severe inflammation can cause them to push against and irritate your uvula. Trauma Trauma to the uvula can happen if you need an intubation, such as during surgery. Your uvula can also be injured during a tonsillectomy. This is a procedure to remove your tonsils, which are located on both sides of your uvula. Your throat and uvula can also become irritated if you have acid reflux disease or if you vomit frequently. Genetics A condition called hereditary angioedema (HAE) can cause swelling of the uvula and throat, as well as swelling of the face, hands, and feet. Other symptoms include nausea, vomiting, and abdominal pain. It’s an uncommon genetic mutation that occurs in 1 in 10,000 to 1 in 50,000 people. It’s rare, but there are case reports of individuals who have an elongated uvula, which can also interfere with breathing. What are the risk factors for a swollen uvula? Risk Factors Anyone can get uvulitis, but adults get it less often than children do.

It’s likely you’ll also need a throat swab to evaluate for strep or to obtain secretions for culture to determine if you have another bacterial or fungal infection. This test is known as the rapid strep test. You may also need a nasal swab to test for influenza. Blood testing can help identify or rule out some other infectious agents. If those tests are inconclusive, you may need to see an allergist. Blood and skin tests can help identify foods or other substances that cause a reaction. Learn more: Allergy testing » If necessary, imaging tests can provide a more detailed view of your throat and the surrounding area. What’s the treatment for a swollen uvula? Treatment When you have something like the common cold, swelling usually clears up on its own without treatment. Otherwise, treatment will depend on how severe your symptoms are, as well as what’s causing the inflammation. Infection Viral infections tend to clear up without treatment. The only upper respiratory infection for which an antiviral medication is available is influenza. Antibiotics can treat bacterial infections. Even after symptoms clear up, take all the medication as prescribed. If your condition may be contagious, stay home until your doctor tells you that you’re no longer at risk of spreading it to others. Allergy If you test positive for an allergy, try to avoid the allergen in the future. Doctors usually treat allergies with antihistamines or steroids. Anaphylaxis is a severe allergic reaction. Doctors use epinephrine to treat this reaction. Hereditary angioedema Your doctor may treat HAE with any of the following: anabolic steroids, or androgens antifibrinolytics C1 inhibitors, such as C1 esterase inhibitor (Berinert) or C1 esterase inhibitor (recombinant) (Ruconest) a plasma kallikrein inhibitor, such as ecallantide (Kalbitor) bradykinin receptor antagonist, such as icatibant injection (Firazyr) Tell your doctor if you have new or worsening symptoms, and follow up as necessary. Tips for relief home treatment If you have a swollen uvula or sore throat, it’s your body’s way of telling you that something is wrong. A few home remedies can help keep you strong and soothe your irritated throat. Make sure you’re getting enough fluids. If your throat hurts when you drink, try drinking small amounts throughout the day. Your urine should be light in color. If it’s dark yellow or brown, you’re not drinking enough and may be dehydrated. Additional tips include the following: Cool your throat by sucking on ice chips. Frozen juice bars or ice cream may also do the trick. Gargle with warm salt water to ease your dry, scratchy throat. Aim for a full night’s sleep, and nap during the day if you can. What’s the outlook? Outlook A swollen uvula isn’t a common occurrence. Most of the time it clears up without treatment. If you have an infection, prompt treatment should take care of the problem within a week or two. If you have allergies that lead to swelling of the uvula or throat, do your best to avoid that allergen. You should also be prepared to deal with an attack if you come into contact with the substance again. If you’ve ever had anaphylaxis, ask your doctor if you should carry injectable epinephrine (EpiPen) in case of emergency. People with HAE must learn to recognize triggers and early warning signs of an attack. Talk to your doctor about how to manage HAE.

Cervical Disc Surgical Technique
Cervical Disc Surgical Technique samer kareem 1,397 Views • 3 years ago

Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.

Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension samer kareem 1,771 Views • 3 years ago

The average time from symptom onset to diagnosis has been reported to be approximately 2 years. Despite recent attempts at increasing the awareness of pulmonary arterial hypertension (PAH), especially associated PAH (APAH), this delay in diagnosis has not changed appreciably in recent years. Early symptoms are nonspecific. Often, neither the patient nor the physician recognizes the presence of the disease, which leads to delays in diagnosis. Complicating matters, idiopathic PAH (IPAH) requires an extensive workup in an attempt to elucidate an identifiable cause of the elevated pulmonary artery pressure. The most common symptoms and their frequency, reported in a national prospective study, are as follows: Dyspnea (60% of patients) Weakness (19%) Recurrent syncope (13%) Additional symptoms include fatigue, lethargy, anorexia, chest pain, and right upper quadrant pain. Cough, hemoptysis, and hoarseness are less common symptoms. Women are more likely to be symptomatic than men.

Giant Blackheads Removal
Giant Blackheads Removal Scott 36,727 Views • 3 years ago

What are blackheads? Blackheads are small bumps that appear on your skin due to clogged hair follicles. These bumps are called blackheads because the surface looks dark or black. Blackheads are a mild type of acne that usually form on the face, but they can also appear on the following body parts: back chest neck arms shoulders Acne affects nearly 50 million Americans and is the most common skin disorder in the United States, according to the American Academy of Dermatology. What do blackheads look like? What causes blackheads? Blackheads form when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil. This oil, called sebum, helps keep your skin soft. Dead skin cells and oils collect in the opening to the skin follicle, producing a bump called a comedo. If the skin over the bump stays closed, the bump is called a whitehead. When the skin over the bump opens, exposure to the air causes it to look black and a blackhead forms. Some factors can increase your chances of developing acne and blackheads, including: producing too much body oil the buildup of the Propionibacterium acnes bacteria on the skin irritation of the hair follicles when dead skins cells don’t shed on a regular basis undergoing hormonal changes that cause an increase in oil production during the teen years, during menstruation, or while taking birth control pills taking certain drugs, such as corticosteroids, lithium, or androgens Some people believe that what you eat or drink can affect acne. Dairy products and foods that increase blood sugar levels, such as carbohydrates, may play a part in triggering acne, but researchers aren’t convinced that there’s a strong connection. ADVERTISING What are symptoms of blackheads? Because of their dark color, blackheads are easy to spot on the skin. They’re slightly raised, although they aren’t painful because they aren’t inflamed like pimples. Pimples form when bacteria invade the blockage in the hair follicle, causing redness and inflammation. How are blackheads treated? Over-the-counter (OTC) treatments Many acne medications are available at drug and grocery stores and online without a prescription. These medications are available in cream, gel, and pad form and are put directly on your skin. The drugs contain ingredients such as salicylic acid, benzoyl peroxide, and resorcinol. They work by killing bacteria, drying excess oil, and forcing the skin to shed dead skin cells. Prescription medications If OTC treatment doesn’t improve your acne, your doctor may suggest that you use stronger prescription medications. Medications that contain vitamin A keep plugs from forming in the hair follicles and promote more rapid turnover of skin cells. These medications are applied directly to your skin and can include tretinoin, tazarotene, or adapalene. Your doctor may also prescribe another type of topical medication that contains benzoyl peroxide and antibiotics. If you have pimples or acne cysts in addition to your blackheads, this type of medication may be particularly helpful. Manual removal Dermatologists or specially trained skin care professionals use a special instrument called a round loop extractor to remove the plug causing the blackhead. After a small opening is made in the plug, the doctor applies pressure with the extractor to remove the clog. Microdermabrasion During microdermabrasion, a doctor or skin care professional uses a special instrument that contains a rough surface to sand the top layers of your skin. Sanding the skin removes clogs that cause blackheads. Chemical peels Chemical peels also remove clogs and get rid of the dead skins cells that contribute to blackheads. During a peel, a strong chemical solution is applied to the skin. Over time, the top layers of the skin peel off, revealing smoother skin underneath. Mild peels are available over the counter, while stronger peels are performed by dermatologists or other skincare professionals. Laser and light therapy Laser and light therapies use tiny beams of intense light to decrease oil production or kill bacteria. Both lasers and light beams reach below the surface of the skin to treat blackheads and acne without damaging the top layers of the skin. How can blackheads be prevented? You can prevent blackheads without spending a lot of money by trying a few of the following ideas: Wash regularly Wash your face when you wake up and before you go to bed to remove oil buildup. Washing more than twice each day can irritate your skin and make your acne worse. Use a gentle cleanser that doesn’t make your skin red or irritated. Some acne cleansing products have antibacterial ingredients that kill P. acnes bacteria. Consider washing your hair every day, too, particularly if it’s oily. Hair oils can contribute to clogged pores. It’s also important to wash your face after you eat oily foods such as pizza, because oil from these foods can clog pores. Use oil-free products Any product that contains oil can contribute to new blackheads. Choose oil-free or noncomedogenic makeup, lotions, and sunscreens to avoid making your problem worse. Try an exfoliating product Exfoliating scrubs and masks remove dead skin cells from your face and can help reduce blackheads. Look for products that don’t irritate your skin.

Cerebral Palsy
Cerebral Palsy samer kareem 6,742 Views • 3 years ago

Cerebral palsy is a disorder of movement, muscle tone or posture that is caused by damage that occurs to the immature, developing brain, most often before birth. Signs and symptoms appear during infancy or preschool years. In general, cerebral palsy causes impaired movement associated with abnormal reflexes, floppiness or rigidity of the limbs and trunk, abnormal posture, involuntary movements, unsteady walking, or some combination of these. People with cerebral palsy may have problems swallowing and commonly have eye muscle imbalance, in which the eyes don't focus on the same object. People with cerebral palsy also may suffer reduced range of motion at various joints of their bodies due to muscle stiffness. Cerebral palsy's effect on functional abilities varies greatly. Some affected people can walk while others can't. Some people show normal or near-normal intellectual capacity, but others may have intellectual disabilities. Epilepsy, blindness or deafness also may be present.
