Healing Process of Bone Fracture
Healing Process of Bone Fracture samer kareem 3,522 Views • 3 years ago

How Does a Bone Heal? All broken bones go through the same healing process. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury. The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone. Diagram of inflammation in a fractured bone Bone production begins when the clotted blood formed by inflammation is replaced with fibrous tissue and cartilage (known as soft callus). As healing progresses, the soft callus is replaced with hard bone (known as hard callus), which is visible on x-rays several weeks after the fracture. Bone remodeling, the final phase of bone healing, goes on for several months. In remodeling, bone continues to form and becomes compact, returning to its original shape. In addition, blood circulation in the area improves. Once adequate bone healing has occurred, weightbearing (such as standing or walking) encourages bone remodeling.​

Treat HEMORRHOIDS
Treat HEMORRHOIDS samer kareem 2,942 Views • 3 years ago

Most of the time, treatment for hemorrhoids involves steps that you can take on your own, such as lifestyle modifications. But sometimes medications or surgical procedures are necessary. Medications If your hemorrhoids produce only mild discomfort, your doctor may suggest over-the-counter creams, ointments, suppositories or pads. These products contain ingredients, such as witch hazel or hydrocortisone, that can relieve pain and itching, at least temporarily. Don't use an over-the-counter cream or other product for more than a week unless directed by your doctor. These products can cause side effects, such as skin rash, inflammation and skin thinning. Minimally invasive procedures If a blood clot has formed within an external hemorrhoid, your doctor can remove the clot with a simple incision, which may provide prompt relief. For persistent bleeding or painful hemorrhoids, your doctor may recommend another minimally invasive procedure. These treatments can be done in your doctor's office or other outpatient setting. Rubber band ligation. Your doctor places one or two tiny rubber bands around the base of an internal hemorrhoid to cut off its circulation. The hemorrhoid withers and falls off within a week. This procedure — called rubber band ligation — is effective for many people. Hemorrhoid banding can be uncomfortable and may cause bleeding, which might begin two to four days after the procedure but is rarely severe. Injection (sclerotherapy). In this procedure, your doctor injects a chemical solution into the hemorrhoid tissue to shrink it. While the injection causes little or no pain, it may be less effective than rubber band ligation. Coagulation (infrared, laser or bipolar). Coagulation techniques use laser or infrared light or heat. They cause small, bleeding, internal hemorrhoids to harden and shrivel. While coagulation has few side effects, it's associated with a higher rate of hemorrhoids coming back (recurrence) than is the rubber band treatment. Surgical procedures If other procedures haven't been successful or you have large hemorrhoids, your doctor may recommend a surgical procedure. Surgery can be performed on an outpatient basis or you may need to stay in the hospital overnight. Hemorrhoid removal. During a hemorrhoidectomy, your surgeon removes excessive tissue that causes bleeding. Various techniques may be used. The surgery may be done with a local anesthetic combined with sedation, a spinal anesthetic or a general anesthetic. Hemorrhoidectomy is the most effective and complete way to treat severe or recurring hemorrhoids. Complications may include temporary difficulty emptying your bladder and urinary tract infections associated with this problem. Most people experience some pain after the procedure. Medications can relieve your pain. Soaking in a warm bath also may help. Hemorrhoid stapling. This procedure, called stapled hemorrhoidectomy or stapled hemorrhoidopexy, blocks blood flow to hemorrhoidal tissue. Stapling generally involves less pain than hemorrhoidectomy and allows an earlier return to regular activities. Compared with hemorrhoidectomy, however, stapling has been associated with a greater risk of recurrence and rectal prolapse, in which part of the rectum protrudes from the anus. Talk with your doctor about what might be the best option for you.

A small-bowel obstruction (SBO) is caused by a variety of pathologic processes. The leading cause of SBO in industrialized countries is postoperative adhesions (60%), followed by malignancy, Crohn disease, and hernias, although some studies have reported Crohn disease as a greater etiologic factor than neoplasia.

Split thickness skin graft

kin grafting is a type of graft surgery involving the transplantation of skin. The transplanted tissue is called a skin graft. Skin grafting is often used to treat: Extensive wounding or trauma Burns Areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans[2] Specific surgeries that may require skin grafts for healing to occur - most commonly removal of skin cancers Skin grafts are often employed after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reduce the course of treatment needed (and time in the hospital), and improve the function and appearance of the area of the body which receives the skin graft.

Benign Cervical Lesions samer kareem 3,191 Views • 3 years ago

By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

Femur Fracture  fixation
Femur Fracture fixation samer kareem 1,332 Views • 3 years ago

Open reduction and internal fixation (ORIF) is surgery used to stabilize and heal a broken bone. You might need this procedure to treat your broken thighbone (femur). The femur is the large bone in the upper part of your leg. Different kinds of trauma can damage this bone, causing it to fracture into 2 or more pieces. This might happen to the part of the femur near your knee, near the middle of the femur, or in the part of the femur that forms part of your hip joint. In certain types of femur fractures, your femur has broken, but its pieces still line up correctly. In other types of fractures (displaced fractures), the trauma moves the bone fragments out of alignment. If you fracture your femur, you usually need ORIF to bring your bones back into place and help them heal. During an open reduction, orthopedic surgeons reposition your bone pieces during surgery, so that they are back in their proper alignment. This contrasts with a closed reduction, in which a healthcare provider physically moves your bones back into place without surgically exposing your bone.

Homan’s sign test also called dorsiflexon sign test is a physical examination procedure that is used to test for Deep Vein Thrombosis (DVT). A positive Homan’s sign in the presence of other clinical signs may be a quick indicator of DVT. Clinical evaluation alone cannot be relied on for patient management, but when carefully performed, it remains useful in determining the need for additional testing (like D-dimer test, ultrasonography, multidetector helical computed axial tomography (CT), and pulmonary angiography) [1][2].

Genital warts are growths on the skin of the genital area and around the anus. They are caused by certain types of the human papilloma virus (HPV). There are more than 100 types of HPV. Some types of HPV produce warts on different parts of the body, like plantar warts on the feet and common hand warts. There is no specific treatment for HPV, but there are treatments for health problems caused by HPV. Genital warts can be treated by your healthcare provider, or with prescription medication. HPV-related cancers are more treatable when diagnosed and treated promptly. For more information, visit www.cancer.org.
