Laparoscopic pelvic urology
Laparoscopic pelvic urology Mohamed Ibrahim 16,767 Views • 2 years ago

Urological surgeons have become proficient at performing complex pelvic urological procedures, such as radical prostatectomy, using the laparoscopic approach. Declan Murphy and Daniel Moon share their experience of four less common procedures they have performed recently using laparoscopic techniques. These include: excision of a urachal cyst; partial cystectomy for endometriosis (combined endoscopic-laparoscopic approach); repair of an intra-peritoneal bladder rupture; and repair of a ureteric injury (combined endoscopic-laparoscopic approach).

A thin polymer film that seals surgical wounds could make sutures a relic of medical history.

Measuring just 50 microns, the film is placed on a surgical wound and exposed to an infrared laser, which heats the film just enough to meld it and the tissue, thus perfectly sealing the wound. Known as Surgilux, the device's raw material is extracted from crab shells and has Food and Drug Administration approval in the US

Weight loss is the most effective nonpharmacologic measure to decrease blood pressure in overweight individuals. Weight loss with other nonpharmacologic measures can prevent or delay the onset of hypertension and reduce the overall risk of cardiovascular events in such patients. In some patients with established hypertension, lifestyle changes alone may control their blood pressure.

Digoxin is derived from the leaves of a digitalis plant. Digoxin helps make the heart beat stronger and with a more regular rhythm. Digoxin is also used to treat atrial fibrillation, a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart).

Complications After Bone Marrow Transplantation
Complications After Bone Marrow Transplantation samer kareem 4,320 Views • 2 years ago

Graft-versus-host disease (GVHD) is a common complication after an allogeneic transplant, a transplant in which cells from a family member, unrelated donor or cord blood unit are used. In GVHD, the immune cells from the donated marrow or cord blood (the graft) attack the body of the transplant patient (the host).

Hypothalamus and Pituitary
Hypothalamus and Pituitary samer kareem 4,483 Views • 2 years ago

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

Adrenoleukodystrophy explained.
Adrenoleukodystrophy explained. samer kareem 4,241 Views • 2 years ago

X-linked adrenoleukodystrophy is a genetic disorder that occurs primarily in males. It mainly affects the nervous system and the adrenal glands, which are small glands located on top of each kidney. In this disorder, the fatty covering (myelin) that insulates nerves in the brain and spinal cord is prone to deterioration (demyelination), which reduces the ability of the nerves to relay information to the brain. In addition, damage to the outer layer of the adrenal glands (adrenal cortex) causes a shortage of certain hormones (adrenocortical insufficiency). Adrenocortical insufficiency may cause weakness, weight loss, skin changes, vomiting, and coma.

Parathyroid Cancer
Parathyroid Cancer samer kareem 4,070 Views • 2 years ago

Parathyroid cancer is a rare disease in which malignant (cancer) cells form in the tissues of a parathyroid gland. The parathyroid glands are four pea-sized organs found in the neck near the thyroid gland. The parathyroid glands make parathyroid hormone (PTH or parathormone). PTH helps the body use and store calcium to keep the calcium in the blood at normal levels.

How Does Diabetes Cause Silent Heart Attacks?
How Does Diabetes Cause Silent Heart Attacks? samer kareem 6,137 Views • 2 years ago

A silent heart attack is a heart attack that has few, if any, symptoms. You may have never had any symptoms to warn you that you've developed a heart problem, such as chest pain or shortness of breath. Having diabetes or prediabetes puts you at increased risk for heart disease and stroke. You can lower your risk by keeping your blood glucose (also called blood sugar), blood pressure, and blood cholesterol close to the recommended target numbersthe levels suggested by diabetes experts for good health.

Why You Got Fat
Why You Got Fat samer kareem 26,573 Views • 2 years ago

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:
