Colonoscopy of Juvenile Polyposis
Colonoscopy of Juvenile Polyposis samer kareem 7,896 Views • 2 years ago

Juvenile polyposis syndrome (JPS) is a hereditary condition that is characterized by the presence of hamartomatous polyps in the digestive tract. Hamartomas are noncancerous (benign) masses of normal tissue that build up in the intestines or other places. These masses are called polyps if they develop inside a body structure, such as the intestines. The term “juvenile polyposis” refers to the type of polyp (juvenile polyp) that is found after examination of the polyp under a microscope, not the age at which people are diagnosed with JPS.

Blood Transfusion
Blood Transfusion samer kareem 1,588 Views • 2 years ago

A blood transfusion is a routine medical procedure that can be lifesaving. During a blood transfusion, donated blood is added to your own blood. A blood transfusion may also be done to supplement various components of your blood with donated blood products. In some cases, a blood transfusion is done with blood that you've donated ahead of time before you undergo elective surgery. During a typical blood transfusion, certain parts of blood are delivered through an intravenous (IV) line that's placed in one of the veins in your arm. A blood transfusion usually takes one to four hours, though in an emergency it can be done much faster.

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.

Constitutional Puberty Delay
Constitutional Puberty Delay samer kareem 4,046 Views • 2 years ago

Delayed puberty is defined as the absence of any signs suggestive of puberty by 14 years of age. In this case, the patient's pubertal delay appears to be constitutional because of his positive family history, absence of syndromic features or systemic illness, and bone age of 12 years. Puberty correlates more closely with bone age than chronological age. On follow-up, the patient will most likely demonstrate a similar onset of puberty as his father.
