Nystagmus is a condition of involuntary (or voluntary, in rare cases) eye movement, acquired in infancy or later in life, that may result in reduced or limited vision. Due to the involuntary movement of the eye, it has been called "dancing eyes"

Laparoscopic liver abscess evacuation
Laparoscopic liver abscess evacuation samer kareem 2,813 Views • 3 years ago

Pyogenic liver abscesses are mainly treated by percutaneous aspiration or drainage under antibiotic cover. If interventional radiology fails, surgical drainage becomes necessary. Recently, we performed laparoscopic liver abscess drainage successfully, and we aimed to focus on the topic in light of a systematic review of the literature.

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism. The goal of the treatment is to reshape the cornea to correct the refractive error of the eye.
The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye's total optical power. Altering the curvature of the cornea changes the way light rays enter the eye. As a result, the light rays can be focused properly onto the retina for clearer vision.
For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape.
The outer layer of the cornea - the epithelium – is capable of replacing itself within a few days after being damaged or removed. The deeper layer of the cornea – the stroma, on the contrary, is a permanent corneal tissue with very limited regenerative capacity. The stroma, if reshaped by a laser, will remain that way permanently.
In this procedure, a thin, circular "FLAP" is created in the surface of the cornea to gain access to the permanent corneal tissue. This can be done with a mechanical cutting tool called a microkeratome, OR, for a blade-free experience, by a femtosecond laser. An excimer laser is then used to remove some corneal tissue to reshape the cornea. Excimer laser uses cool ultraviolet light beams to vaporize microscopic amounts of tissue in a precise manner to accurately reshape the cornea. The excimer laser is computer-controlled and is programmed based on the patient’s refractive error. The flap is then laid back in place and is allowed to heal.
LASIK eye surgery is mostly painless and can be completed within minutes. Improved vision can usually be seen overnight.

PRK, or photorefractive keratectomy, was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. In PRK, NO flap is created. Rather, the epithelial cells on the eye surface are simply removed. An excimer laser is then used to reshape the cornea just like it does in LASIK.
The vision correction outcomes of PRK surgery are comparable to those of LASIK, but the recovery period is longer. This is because the epithelium is completely removed in PRK and it takes a few days to regenerate. PRK patients also have more discomfort and haziness of vision in the first few days after the surgery. Improved vision also takes longer to achieve.
PRK does, however, offer certain advantages. Because PRK does not involve creation of a flap, which contains both epithelial and deeper stromal tissue, the entire thickness of the stroma is available for treatment. The treatment range is therefore higher. This is particularly useful for patients with high levels of myopia or for those whose cornea is too thin for LASIK. PRK is also free of flap-related complication risks.

Biceps Tenodesis
Biceps Tenodesis samer kareem 12,675 Views • 3 years ago

Biceps tenodesis surgery is performed when the biceps tendon is damaged, or the rotator cuff tendon or cartilage ring in the shoulder is torn. The biceps tendon is a strong rope‐like structure connecting the upper end of the biceps muscle to the bones in the shoulder. In biceps tenodesis surgery, the biceps tendon is separated from the shoulder and reattached to the humerus, or the upper arm bone.

Acromegaly is usually caused by a noncancerous tumor. Middle-aged adults are most commonly affected. Symptoms include enlargement of the face, hands, and feet. Prompt treatment is needed to avoid serious illness. Drugs can reduce the effects of growth hormone. If needed, surgery and radiation may be used to remove tumor cells.

Carotid Artery Disease
Carotid Artery Disease samer kareem 1,659 Views • 3 years ago

Carotid artery stenosis can be caused by cholesterol build-up in the blood vessels (atherosclerosis). Blood clots can form in this area and travel up to the brain. This condition may be present for a long time before symptoms appear. When symptoms do occur, stroke or brief stroke-like attacks are common. If this condition is discovered as a result of a stroke or stroke-like attack, cholesterol lowering medications and blood thinners may be used to improve blood flow to the brain. If the degree of narrowing is severe, surgery may be needed to open the blood vessel.

Serotonin Syndrome
Serotonin Syndrome samer kareem 3,449 Views • 3 years ago

Symptoms of serotonin syndrome include a classic triad of mental status changes (eg, anxiety, delirium, confusion, restlessness), autonomic dysregulation (eg, diaphoresis, tachycardia, hypertension, hyperthermia, diarrhea, mydriasis), and neuromuscular hyperactivity (eg, hyperreflexia, tremor, rigidity, myoclonus, ocular clonus). Serotonin syndrome is clinically diagnosed and laboratory tests are used to rule out other etiologies. It usually occurs due to inadvertent interactions between drugs, therapeutic use of multiple serotonergic agents, or serotonergic medication overdose. Treatment involves discontinuation of serotonergic drugs, supportive measures, and sedation with benzodiazepines. In severe cases, a serotonin antagonist (cyproheptadine) may be used.
