Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,156 Views • 3 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

Giant Cell (Benign) Tumor of the Finger
Giant Cell (Benign) Tumor of the Finger samer kareem 22,381 Views • 3 years ago

Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar)

Penile Implant Surgery Treatment
Penile Implant Surgery Treatment samer kareem 13,808 Views • 3 years ago

A penile prosthesis is another treatment option for men with erectile dysfunction. These devices are either malleable (bendable) or inflatable. The simplest type of prosthesis consists of a pair of malleable rods surgically implanted within the erection chambers of the penis. With this type of implant the penis is always semi-rigid and merely needs to be lifted or adjusted into the erect position to initiate sex. This type of implant is a good choice for men with spinal cord injuries and/or limited hand strength. Today, many men choose a hydraulic, inflatable prosthesis, which allows them to have an erection when they choose, and it's easier to conceal. It is also more natural. A penile implant is usually used when there is a clear medical cause for ED and when the problem is unlikely to resolve or improve naturally or with other medical treatments. Sometimes a penile prosthesis is implanted during surgery to reconstruct the penis when scarring has caused erections to curve (Peyronie's disease). Penile implant surgeries take about an hour and are typically done in an outpatient center. A man can resume sexual intercourse by 6 weeks after surgery.

In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem. Treatment involves compression stockings, exercise, or procedures to close or remove the veins.

Epley Maneuver to Treat BPPV
Epley Maneuver to Treat BPPV samer kareem 5,569 Views • 3 years ago

The Epley maneuver is a series of movements, normally carried out on a person by a doctor, to relieve the symptoms of BPPV. Research has found it to be an easy, safe, and effective treatment for the condition in both the long- and short-term. The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.

Doctors give soldier New Ear after growing it in her arm

Shamika Burrage survived a near-fatal car accident two years ago, but not without losing something pretty important: her left ear. Now, thanks to a novel procedure performed at an Army medical center in Texas, Burrage is getting that ear back in a most unusual way. Plastic surgeons harvested cartilage from Burrage's ribs to create a new ear and then grew it under the skin of her forearm. Then the doctors at William Beaumont Army Medical Center in El Paso successfully transplanted the ear from her arm to her head. The technique -- a first time in the Army -- is called prelaminated forearm free flap, said Lt. Col. Owen Johnson III, chief of plastic and reconstructive surgery at William Beaumont Army Medical Center. Some of the big advantages of it is that it reduced the chance of more scarring around Burrage's ear. Also, growing the ear under the skin of her forearm allows new blood vessels to form. "(The ear) will have fresh arteries, fresh veins and even a fresh nerve so she'll be able to feel it," Johnson said on the US Army's website. Burrage, a 21-year-old private, still has to endure two more surgeries, but she's feeling more optimistic about the future than ever in the years since her accident. "It's been a long process for everything, but I'm back," said Burrage.

Amputation of the Index Finger
Amputation of the Index Finger Surgeon 25,407 Views • 3 years ago

An amputation is the removal of an extremity or appendage from the body. Amputations in the upper extremity can occur as a result of trauma, or they can be performed in the treatment of congenital or acquired conditions. Although successful replantation represents a technical triumph to the surgeon, the patient's best interests should direct the treatment of amputations. The goals involved in the treatment of amputations of the upper extremity include the following : Preservation of functional length Durable coverage Preservation of useful sensibility Prevention of symptomatic neuromas Prevention of adjacent joint contractures Early return to work Early prosthetic fitting These goals apply differently to different levels of amputation. Treatment of amputations can be challenging and rewarding. It is imperative that the surgeon treat the patient with the ultimate goal of optimizing function and rehabilitation and not become absorbed in the enthusiasm of the technical challenge of the replantation, which could result in poorer outcome and greater financial cost due to lost wages, hospitalization, and therapy.

Starting dialysis at age 75 years or older -- outcomes data to help in shared decision making. Scott 108 Views • 3 years ago

Research from Mayo Clinic finds that half of elderly patients who start dialysis after age 75 will die within one year.

Lead study author and a health care delivery scholar with the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery, Dr. Bjorg Thorsteinsdottir says many elderly patients and their families feel that they have no choice but to start dialysis, with several expressing regret from having initiated therapy.

The findings were presented at the American Society of Nephrology's Kidney Week 2013 in Atlanta.
