A surgeon creates an arteriovenous fistula by making a connection between an artery (which carries blood away from the heart) and a vein (which carries blood back to the heart). This artificial connection allows the vein to become larger and for the walls of the vein to thicken, a process termed maturation. A mature fistula makes it easier for the vein to be punctured repeatedly for dialysis. Maturation typically takes three to six months to occur, but in rare cases, can take up to a year. This makes advance planning for an arteriovenous fistula important. When a patient is felt to be approximately a year away from requiring dialysis, the patient should be referred for evaluation for possible creation of an arteriovenous fistula.
minimally invasive procedure is the new gold standard for hemorrhoidectomy, according to American and European experts in the field. The procedure, known as PPH (procedure for prolapse and hemorrhoids) stapled hemorrhoidectomy, combines hemorrhoidal devascularization and repositioning to return the veins to the anal canal. “This year, this is the revolutionary new procedure in the United States,” Gary Hoffman, MD, clinical faculty member in general and colorectal surgery, Cedars-Sinai Medical Center, Los Angeles, told General Surgery News after moderating a live PPH telesurgery at the 2003 annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons.
The thyroid gland lies in the midline of the anterior neck, just caudal to the thyroid cartilage. To inspect the thyroid gland, the examiner stands in front of the patient. The examiner asks the seated patient to dorsiflex (extend) the neck and swallow a sip of water. Minor enlargement of the gland may only become apparent on inspection in this position. Palpation of the thyroid gland is typically performed with the examiner standing behind the patient. Both lobes and the isthmus of the thyroid gland should be palpated for any nodules or diffuse enlargement. Mobility of the thyroid gland with swallowing should be assessed with palpation. Nodules arising from the thyroid gland typically move with swallowing. A hard, fixed thyroid gland could indicate malignancy. If a central nodule is identified, the patient is asked to protrude the tongue. Upward movement of the central nodule on protrusion of the tongue indicates a thyroglossal cyst. Auscultation is performed at the superior poles of bilateral lobes as this is where the superior thyroid artery is most superficial and bifurcates into its terminal branches. A bilateral bruit over the superior poles suggests Graves disease. Examination of the thyroid gland is completed by palpating the regional cervical lymph nodes for any enlargement.

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, often the kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in a woman whose blood pressure had been normal. Even a slight rise in blood pressure may be a sign of preeclampsia. Left untreated, preeclampsia can lead to serious — even fatal — complications for both you and your baby. If you have preeclampsia, the only cure is delivery of your baby. If you're diagnosed with preeclampsia too early in your pregnancy to deliver your baby, you and your doctor face a challenging task. Your baby needs more time to mature, but you need to avoid putting yourself or your baby at risk of serious complications.
What Happens During an Erection?
In order to attain an erection, messages from the brain and other sense organs trigger the arteries of the penis to dilate. This allows an increased amount of blood to flow into three columns of spongy tissue in the penis.
As the arteries supplying blood to the corpus spongiosum and to the two larger columns, the corpus cavernosa, become filled with blood; the penis grows and becomes rigid. Pressure of the engorged tissue against the veins in the penis effectively traps blood within the penis until climax is reached or the sensation wanes.
What Are Penile Implants?
Impotence, or the inability to attain or maintain an erection, can be caused by a disruption at any stage in this process. Several types of penile implants are available that create an artificial erection. Two common types of implants are the semi-rigid malleable rod and the inflatable implant.
•The semirigid malleable rod is usually made of plastic with a core of flexible wire. These rods can be bent down to conceal the penis under clothing or raised to form an artificial erection.
•The inflatable implant is more complex and involves several working parts: a reservoir of fluid that is implanted into the abdomen, a pump system located in the scrotal sac near the testes, and two inflatable cylinders.
How Penile Implants Help Erectile Fuctioning
In order to attain an erection, the scrotal pump must be squeezed repeatedly to propel fluid into the penile cylinders. When an erection is no longer desired, a release valve is pressed on the side of the pump and the cylinders deflate.
Before Having Penile Implant Surgery
Persons considering these types of implants should speak with their physician or healthcare professional about possible risks and complications.
