Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are absent due to the development of the frontal lobes as a child transitions normally into child development.
Dr. Jeffrey Ojemann, director of epilepsy surgery at Seattle Children's Hospital, explains a cutting-edge treatment for epilepsy: minimally invasive MRI-guided laser ablation surgery. Laser ablation surgery is much safer and more precise than other treatments, with fewer side effects.
A special thanks to patient Keoni Giauque.

Giant cell arteritis is an inflammation of the lining of arteries. Most often, it affects the arteries in your head, especially those in your temples. For this reason, giant cell arteritis is sometimes called temporal arteritis. Giant cell arteritis frequently causes headaches, scalp tenderness, jaw pain and vision problems. If left untreated, it can lead to stroke or blindness. Prompt treatment with corticosteroid medications usually relieves symptoms of giant cell arteritis and may prevent loss of vision. You'll likely begin to feel better within days of starting treatment. But even with treatment, relapses are common. You'll need to visit your doctor regularly for checkups and treatment of any side effects from taking corticosteroids.
Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow. Examples of beta blockers Some beta blockers mainly affect your heart, while others affect both your heart and your blood vessels. Which one is best for you depends on your health and the condition being treated. Examples of oral beta blockers include: Acebutolol (Sectral) Atenolol (Tenormin) Bisoprolol (Zebeta) Metoprolol (Lopressor, Toprol-XL) Nadolol (Corgard) Nebivolol (Bystolic) Propranolol (Inderal LA, InnoPran XL)
Rubber band ligation is a procedure in which the hemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the hemorrhoid. This treatment is only for internal hemorrhoids. To do this procedure, a doctor inserts a viewing instrument (anoscope) into the anus. The hemorrhoid is grasped with an instrument, and a device places a rubber band around the base of the hemorrhoid. The hemorrhoid then shrinks and dies and, in about a week, falls off. A scar will form in place of the hemorrhoid, holding nearby veins so they don't bulge into the anal canal. The procedure is done in a doctor's office. You will be asked whether the rubber bands feel too tight. If the bands are extremely painful, a medicine may be injected into the banded hemorrhoids to numb them. After the procedure, you may feel pain and have a sensation of fullness in the lower abdomen. Or you may feel as if you need to have a bowel movement. Treatment is limited to 1 to 2 hemorrhoids at a time if done in the doctor's office. Several hemorrhoids may be treated at one time if the person has general anesthesia. Additional areas may be treated at 4- to 6-week intervals.
Hyponatremia is defined as a serum sodium of less than 135 Meq per litre and occurs in upto 22 % of hospitalised patients. The causes of hyponatremia may be understood based on the pre-existing volume status of the patient which may either be hypovolemic, euvolemic or hypervolemic hyponatremia. This presentation discusses in detail, the causes of these underlying conditions. Also mentioned are the clinical features and management options and therapeutic sodium targets in patients with hyponatremia. Drugs such as demeclocycline and vaptans (Tolvaptan, Conivaptan) are also mentioned as management options which may be used on a case to case basis. Finally, the all important targets of sodium correction over 24 hours are also mentioned, along with a practical formula for calculation of sodium deficit which is explained with an example.
Your baby's sex is set at conception. At around 7 weeks, your baby's internal sex organs – such as ovaries and testes – begin to form in the abdomen. Male and female sex organs and genitalia look the same at this stage because they're derived from the same structures. At around 9 weeks, boys and girls begin to develop differently. In girls, a tiny bud emerges between the tissue of the legs. This bud will become the clitoris. The membrane that forms a groove below the bud separates to become the labia minora and the vaginal opening. By 22 weeks, the ovaries are completely formed and move from the abdomen to the pelvis. They already contain a lifetime supply of 6 million eggs. In boys, the bud develops into the penis and starts to elongate at around 12 weeks. The outer membrane grows into the scrotal sac that will later house the testicles. By 22 weeks, the testes have formed in the abdomen. They already contain immature sperm. Soon they'll begin their descent to the scrotum, but it's a long journey. They'll reach their destination late in pregnancy, or for some boys, after birth. If you're eager to find out whether you're having a girl or a boy, you'll have to wait until you're at least 17 weeks pregnant. That's when the genitals have developed enough to be seen on an ultrasound.
3D scans show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension. It's natural to be really excited by the prospect of your first scan. But some mums find the standard 2D scans disappointing when all they see is a grey, blurry outline.
An ectopic pregnancy (EP) is a condition in which a fertilized egg settles and grows in any location other than the inner lining of the uterus. The vast majority of ectopic pregnancies are so-called tubal pregnancies and occur in the Fallopian tube.
The bone marrow aspiration is usually done first. The doctor makes a small incision, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging.
