With so many antibiotics available, it isn't possible to list all of them here. But common antibiotics that are generally considered safe during pregnancy include penicillins (such as amoxicillin and ampicillin), cephalosporins (such as cephalexin), and erythromycin.

Basal Joint Arthroscopic Debridement
Basal Joint Arthroscopic Debridement samer kareem 1,206 विचारों • 2 वर्षों पहले

The procedure was performed under wrist block regional anesthesia with tourniquet control. A single Chinese finger trap was used on the thumb with 5 to 8 lb of ongitudinal traction. The arm was held down with wide tape around the tourniquet securing it to the hand table to serve as countertraction. A shoulder holder, rather than a traction tower, was used to facilitate fluoroscopic intervention more easily. The Trapeziometacarpal joint was detected by palpation. Joint distension was achieved by injecting 1 to 3 mL of normal saline (Fig. 1). It is important to distally direct the needle approximately 20 degrees to clear the dorsal flare of the metacarpal base and enter the joint capsule. This course should be reproduced upon entering with arthroscopic sleeve/ trocar assembly to minimize iatrogenic cartilage injury. Fluid distention is important to facilitate this. The incision for the 1-R (radial) portal, used for proper assessment of the dorsoradial ligament, posterior oblique ligament, and ulnar collateral ligament, was placed just volar to the abductor pollicis longus tendon. The incision for the 1-U (ulnar) portal, for better evaluation of the anterior oblique ligament and ulnar collateral ligament, was made just ulnar to the extensor pollicis brevis tendon. A short-barrel, 1.9-mm, 30- degree inclination arthroscope was used for complete visualization of the CMC joint surfaces, capsule, and ligaments, and then appropriate management was done, as dictated by the stage of the arthritis detected (Fig. 2A). A full-radius mechanical shaver with suction was used in all the cases, particularly for initial debridement and visualization. Most of the cases were augmented with radiofrequency ablation to perform a thorough synovectomy and radiofrequency was also used to perform chondroplasty in the cases with focal articular cartilage wear or fibrillation. Chondroplasty refers to thedebridement of the fibrillated cartilage to improve vascularity of the cartilage and enhance the growth of fibrocartilage. Ligamentous laxity and capsular attenu- ation were treated with thermal capsulorraphy using a radiofrequency shrinkage probe. We were careful to avoid thermal necrosis; hence, a striping technique was used to tighten the capsule of the lax joints. The striping technique refers to thermal shrinkage performed in longitudinal stripes on the lax capsule, so as to leave vascular zones between the stripes; hence, thermal necrosis is prevented. Arthroscopic stage I disease was characterized by synovitis without any cartilage wear, wherein a synovectomy coupled with thermal capsulor- raphy as described was performed.

Epstein Barr Virus
Epstein Barr Virus samer kareem 1,625 विचारों • 2 वर्षों पहले

Epstein-Barr is the virus that causes mononucleosis. You might know this disease better by its nickname, "mono." It's also called the "kissing disease" because of one way you can spread it to someone else. Even though Epstein-Barr virus (EBV) isn't a household name, you've probably been infected without knowing it. Lots of people carry the virus but don't get sick

arteriosclerosis
arteriosclerosis samer kareem 1,015 विचारों • 2 वर्षों पहले

Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.

Folic Acid & Pregnancy
Folic Acid & Pregnancy samer kareem 1,634 विचारों • 2 वर्षों पहले

If you're pregnant or might become pregnant, it's critically important to get enough folic acid, the synthetic form of vitamin B9, also known as folate. Folic acid helps prevent neural tube defects (NTDs) – serious birth defects of the spinal cord (such as spina bifida) and the brain (such as anencephaly).

Lumbar Fusion of L5-S1 Surgery
Lumbar Fusion of L5-S1 Surgery samer kareem 3,938 विचारों • 2 वर्षों पहले

At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may re­sult when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

Sinus infections caused by viruses can use home (over-the-counter, OTC) treatments such as pain and fever medications (acetaminophen [Tylenol]), decongestants, and mucolytics. In addition, some health-care professionals suggest nasal irrigation or a sinus rinse solution to help relieve symptoms of sinus infections, even chronic sinusitis symptoms.

Temporomandibular joint dysfunction (TMJD)
Temporomandibular joint dysfunction (TMJD) samer kareem 1,754 विचारों • 2 वर्षों पहले

Your temporomandibular joint is a hinge that connects your jaw to the temporal bones of your skull, which are in front of each ear. It lets you move your jaw up and down and side to side, so you can talk, chew, and yawn. Problems with your jaw and the muscles in your face that control it are known as temporomandibular disorders (TMD). But you may hear it wrongly called TMJ, after the joint.

Spina Bifida. NTD
Spina Bifida. NTD samer kareem 1,641 विचारों • 2 वर्षों पहले

Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way. When the neural tube doesn’t close all the way, the backbone that protects the spinal cord doesn’t form and close as it should. This often results in damage to the spinal cord and nerves. Spina bifida might cause physical and intellectual disabilities that range from mild to severe. The severity depends on: The size and location of the opening in the spine. Whether part of the spinal cord and nerves are affected.

Suturing Heart Valve
Suturing Heart Valve samer kareem 2,176 विचारों • 2 वर्षों पहले

There are several ways to do minimally invasive aortic valve surgery. Techniques include min-thoracotomy, min-sternotomy, robot-assisted surgery, and percutaneous surgery. To perform the different procedures: Your surgeon may make a 2-inch to 3-inch (5 to 7.5 centimeters) cut in the right part of your chest near the sternum (breastbone). The muscles in the area will be divided. This lets the surgeon reach the heart and aortic valve. Your surgeon may split only the upper portion of your breast bone allowing exposure to the aortic valve. For robotically-assisted valve surgery, the surgeon makes 2 to 4 tiny cuts in your chest. The surgeon uses a special computer to control robotic arms during the surgery. A 3D view of the heart and aortic valve are displayed on a computer in the operating room.
