Gower Sign Video
Gower Sign Video Surgeon 12,501 Views • 2 years ago

Gowers' sign is a medical sign that indicates weakness of the proximal muscles, namely those of the lower limb. The sign describes a patient that has to use his hands and arms to "walk" up his own body from a squatting position due to lack of hip and thigh muscle strength. It is named for William Richard Gowers. Gowers' sign is classically seen in Duchenne muscular dystrophy, but also presents itself in centronuclear myopathy, myotonic dystrophy and various other conditions associated with proximal muscle weakness. For this maneuver, the patient is placed on the floor away from any objects that could otherwise be used to pull oneself to a standing position. It is also used in testing paraplegia.

WORM LIKE CREATURE REMOVED FROM EYE
WORM LIKE CREATURE REMOVED FROM EYE DrHouse 49,269 Views • 2 years ago

PARASITE REMOVED FROM THE EYEBALL OF A YOUNG N, NOT FOR THE SCREAMISH!Loa Loa worms (also known as the "eye worm") are classified as filarial worms, meaning they thrive in human tissue. The Loa Loa worm is also called the "eye worm" because they often migrate through the eye and surrounding subsurface areas. At one time, prior to the 1920s, loa loa worm infections occurred in the United States. Today, however, they mainly infect people who are native to Sudan, and those who live in or near Central and West Africa's swamps and rain forests.

Loiasis is the infestation of loa loa worms in humans. The larvae are first collected from an infected individual when a mango fly (horsefly) or a deer fly bites the individual, and acquires the larvae. The larvae then progress through the fly's body, finally reaching the feeding tube. They are then transferred to a human host when the fly bites the human. The larvae may remain unnoticed for months or years before becoming an adult, mating, and producing offspring.

Adult female Loa Loa worms can reach a length of 2 1/2 inches while males are approximately half that size. Loa Loa worms can live approximately fifteen years inside their human hosts. They travel continuously through connective and deep tissue, often without the victim experiencing any sensation other than occasional itching.

It is when the worm slows or reaches a sensitive spot that a person will often feel the greatest discomfort. At this point, immune reactions may also include localized redness and a condition called "Calabar" swelling. Skin eruptions and muscle pain may be evident.

When the Loa Loa worm reaches the eye tissue, it can be easily seen and felt within the eyeball for up to an hour. It is usually removed under local anesthesia if the patient is within proximity of a qualified physician. When an adult worm dies, the surrounding tissue may abscess and require excision. Encephalitis can occur if the worm reaches the brain.

After mating, the female will deposit eggs - called microfilariae. These tiny organisms then travel in a worm-like fashion in the bloodstream during daytime hours, when potential host flies are most abundant. They congregate in the lungs at night.

A Loa Loa worm infection is rarely fatal and treatments often cause more life-threatening side effects than the actual infestation, especially if the worms are widespread. The most common treatments are DEC (diethylcarbamazine) and Ivermectin

Cervical cerclage can be placed via transvaginal, open transabdominal, or laparoscopic transabdominal approach, preferably before pregnancy. Recurrent late miscarriages may be due to a weak (sometimes called an incompetent) cervix that shortens or opens too early in pregnancy. Cervical cerclage involves placing a stitch around the upper part of the cervix to keep it closed; the operation may be carried out through the vagina, or through the abdomen, as an open or laparoscopic ('keyhole') procedure.

Esophageal Dilation Procedure
Esophageal Dilation Procedure samer kareem 4,584 Views • 2 years ago

What is Esophageal Dilation?Esophageal dilation is a procedure that allows your doctor to dilate, or stretch, a narrowed area of your esophagus [swallowing tube]. Doctors can use various techniques for this procedure. Your doctor might perform the procedure as part of a sedated endoscopy. Alternatively, your doctor might apply a local anesthetic spray to the back of your throat and then pass a weighted dilator through your mouth and into your esophagus. Why is it Done? The most common cause of narrowing of the esophagus, or stricture, is scarring of the esophagus from reflux of acid occurring in patients with heartburn.

Wrist ganglion aspiration
Wrist ganglion aspiration samer kareem 19,472 Views • 2 years ago

A nonsurgical method of treating a ganglion is to drain the fluid from (aspirate) the ganglion sac. Your doctor can do this in the office using the following procedure: The ganglion area is cleaned with an antiseptic solution. A local anesthetic is injected into the ganglion area to numb the area. When the area is numb, the ganglion sac is punctured with a sterile needle. The fluid is drawn out of the ganglion sac. The ganglion collapses. A bandage and, in some cases, a splint are used for a few days to limit movement and prevent the ganglion sac from filling again. Treating a ganglion by draining the fluid with a needle may not work because the ganglion sac remains intact and can fill again, causing the ganglion to return. For this reason, your doctor may puncture the sac with the needle 3 or 4 times so the sac will collapse completely. Even then, the ganglion is likely to come back.

Vertigo Treatment
Vertigo Treatment samer kareem 2,784 Views • 2 years ago

Vertigo is a sensation of spinning. If you have these dizzy spells, you might feel like you are spinning or that the world around you is spinning. Causes of Vertigo Vertigo is often caused by an inner ear problem. Some of the most common causes include: BPPV. These initials stand for benign paroxysmal positional vertigo. BPPV occurs when tiny calcium particles (canaliths) clump up in canals of the inner ear. The inner ear sends signals to the brain about head and body movements relative to gravity. It helps you keep your balance. BPPV can occur for no known reason and may be associated with age. Meniere's disease. This is an inner ear disorder thought to be caused by a buildup of fluid and changing pressure in the ear. It can cause episodes of vertigo along with ringing in the ears (tinnitus) and hearing loss. Vestibular neuritis or labyrinthitis. This is an inner ear problem usually related to infection (usually viral). The infection causes inflammation in the inner ear around nerves that are important for helping the body sense balance

Genital warts are soft growths that appear on the genitals. Genital warts are a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). These skin growths can cause pain, discomfort, and itching. They are especially dangerous for women because some types of HPV can also cause cancer of the cervix and vulva.

Face transplantation surgery

Face transplant candidates go through an extensive screening process that is likely to last several months. This screening includes a psychiatric and social support evaluation and a series of imaging tests to help determine a patient’s physical and mental readiness for the procedure. If, upon completion of the screening process, it is determined that a patient is a suitable candidate, we will place the patient on a transplant waiting list. We will then begin working with the New England Organ Bank (NEOB) team to find a donor who matches the recipient’s tissue requirements – e.g., similar age, right blood type. This search could take many months, and, if a suitable donor is not found within one year, we will speak with the patient to determine whether they’re willing to continue waiting. When a donor is found, we will immediately inform the patient about when to arrive at the hospital for the operation. As the timing for this type of procedure is extremely important, patients are expected to be readily available, i.e., reside within a 12-hour travel radius of BWH.

Tibial Stress Fracture
Tibial Stress Fracture samer kareem 7,331 Views • 2 years ago

-Tibial stress fractures are common in athletes and nonathletes who suddenly increase their physical activity. Clinical features include pain, localized tenderness, and swelling. Plain x-ray is <50% sensitive for stress fractures, especially in the first 2-3 weeks after the onset of symptoms. MRI is preferred over bone scan or ultrasound as it can show the fracture line that extends through the cortex into the medullary line. MRI can also identify ligament, muscle, and cartilage injuries. However, MRI findings may be persistently abnormal for up to 1 year after the stress fracture has healed.

Basal Joint Arthroscopic Debridement

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.
