Risk of a scaphoid fracture not healing
Risk of a scaphoid fracture not healing samer kareem 2,967 Views • 2 years ago

Despite the effective diagnostic and treatment options available today, Dr. Wolfe notes that he continues to see a high number of untreated scaphoid fractures that have progressed to nonunion. However, he adds that this may not be the result of a missed diagnosis, but rather more related to the relatively innocuous injury that causes a low level of suspicion. Recognition and awareness of scaphoid fractures is higher today among primary care providers, emergency room physicians, pediatricians, and sports trainers, but fully 15% of patients with suggestive physical findings and normal initial x-rays will have an “occult”, or concealed, scaphoid fracture. Specialized imaging studies are critical at an early stage to reduce the chance of scaphoid nonunion.

People with celiac disease may lose weight because their bodies are not able to absorb enough nutrients from food. Over time, a range of problems may develop as a result of the body's reaction to gluten — from skin rashes and lactose intolerance to infertility, bone weakness and nerve damage.

Correction of knock knee deformity

This is a technique of correcting knock knee (genu valgum) deformity by surgery. Highligh of the technique is that the bone is not cut, but merely weakened. The advantage is that it provides accuracy to the surgeon, and rapid healing. Once corrected, the bone is held in place with a special plate (Tomofix), which permits walking with crutches the very next day.

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,507 Views • 2 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

Frontotemporal degeneration (FTD) is a disease process that results in progressive damage to the temporal and/or frontal lobes of the brain. It causes a group of brain disorders that share many clinical features.

Digoxin mechanism of action

Digoxin is used to treat heart failure, usually along with other medications. It is also used to treat a certain type of irregular heartbeat (chronic atrial fibrillation). Treating heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treating an irregular heartbeat can decrease the risk for blood clots, an effect that may reduce your risk for a heart attack or stroke.

Elbow Joint Arthrocentesis
Elbow Joint Arthrocentesis samer kareem 1,156 Views • 2 years ago

Arthrocentesis involves both the puncture of a joint and the aspiration of its synovial fluid. It is typically used to make an accurate diagnosis of a painful, warm, swollen joint. Removal of excess fluid can be therapeutic. Analysis of the removed fluid helps to decipher its etiology. [1]

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.

arteriosclerosis
arteriosclerosis samer kareem 1,015 Views • 2 years ago

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.
