Breast Cysts
Breast Cysts samer kareem 6,027 Views • 3 years ago

The lumps may be hard or rubbery and can appear as a single breast lump that may be large or small. Fibrocystic changes also can appear as thickening of the breast tissue. Fibrocystic changes can occur in one or both breasts and are the most common cause of benign breast lumps in women age 35 to 50.

Closure of Wound by Stress Relaxation
Closure of Wound by Stress Relaxation samer kareem 1,747 Views • 3 years ago

Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The TopClosure tension-relief system (TRS) is a novel device for wound closure closure, providing secured attachment to the skin through a wide area of attachment, in an adjustable manner, enabling primary closure of medium to large skin defects. The aim of this study was to evaluate the efficiency of the TopClosure TRS as a substitute for skin grafting and flaps for primary closure of large soft tissue defects by stress-relaxation. We present three demonstrative cases requiring resection of large to huge tumors customarily requiring closure by skin graft or flaps. TRS was applied during surgery serving as a tension-relief platform for tension sutures, to enable primary skin-defect closure by cycling of stress-relaxation, and following surgery as skin-secure system until complete wound closure. All skin defects ranging from 7 to 26 cm in width were manipulated by the TRS through stress-relaxation, without undermining of skin, enabling primary skin closure and eliminating the need for skin grafts and flaps. Immediate wound closure ranged 26 to 135 min. TRS was applied for 3 to 4 weeks. Complications were minimal and donor site morbidity was eliminated. Surgical time, hospital stay and costs were reduced and wound aesthetics were improved. In this case series we present a novel technology that enables the utilization of the viscoelastic properties of the skin to an extreme level, extending the limits of primary wound closure by the stress-relaxation principle. This is achieved via a simple device application that may aid immediate primary wound closure and downgrade the complexity of surgical procedures for a wide range of applications on a global scale.

Superior Capsular Reconstruction
Superior Capsular Reconstruction samer kareem 1,401 Views • 3 years ago

Superior capsule reconstruction (SCR) is a promising alternative treatment for irreparable posterosuperior rotator cuff tears (Figure 1). It utilizes a graft from the superior glenoid to the greater tuberosity to stabilize the humeral head. In a study by Mihata and colleagues of 23 patients who underwent SCR with a fascia lata autograft at a minimum of 2 years follow-up, the American Shoulder and Elbow Surgeons (ASES) score improved significantly from 23.5 preoperatively to 92.9. Postoperative MRI showed 83% of patients had intact reconstructions with no progression of muscle atrophy.

Croup is a common respiratory camera.gif problem in young children. It tends to occur in the fall and winter. Its main symptom is a harsh, barking cough. Croup causes swelling and narrowing in the voice box, windpipe, and breathing tubes that lead to the lungs. This can make it hard for your child to breathe. An attack of croup can be scary, but it is rarely serious. Children usually get better in several days with rest and care at home.

Yannas had been studying collagen, a protein found in human skin. Teaming up during the 1970s, the two made a polymer (a chemical compound made of multiple repeating units). Using collagen fibers and a long sugar molecule, they formed a porous (full of small holes) material resembling skin.

This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.

Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.

Most times, a pulmonary embolism is caused by blood clots that travel from the legs or, rarely, other parts of the body (deep vein thrombosis, or DVT). Symptoms include shortness of breath, chest pain, and cough. Prompt treatment to break up the clot greatly reduces the risk of death. This can be done with blood thinners and drugs or procedures. Compression stockings and physical activity can help prevent clots from forming in the first place.

Primary sclerosing  cholangitis
Primary sclerosing cholangitis samer kareem 2,500 Views • 3 years ago

Primary sclerosing (skluh-ROHS-ing) cholangitis (koh-lan-JIE-tis) is a disease of the bile ducts, which carry the digestive liquid bile from your liver to your small intestine. In primary sclerosing cholangitis, inflammation causes scars within the bile ducts. These scars make the ducts hard and narrow and gradually cause serious liver damage. In most people with primary sclerosing cholangitis, the disease progresses slowly and can lead to liver failure, repeated infections, and tumors of the bile duct or liver. Liver transplant is the only known cure for primary sclerosing cholangitis. The search for other treatments to slow or stop primary sclerosing cholangitis is ongoing, and scientists have turned up many promising leads. Until better treatments are proved safe and effective, though, care for primary sclerosing cholangitis focuses on monitoring liver function, managing symptoms and, when possible, doing procedures that temporarily open blocked bile ducts.

Spleen Anatomy and Physiology
Spleen Anatomy and Physiology samer kareem 3,044 Views • 3 years ago

The spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.
