Hyperparathyroidism is an excess of parathyroid hormone in the bloodstream due to overactivity of one or more of the body's four parathyroid glands. These glands are about the size of a grain of rice and are located in your neck. The parathyroid glands produce parathyroid hormone, which helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper functioning. Two types of hyperparathyroidism exist. In primary hyperparathyroidism, an enlargement of one or more of the parathyroid glands causes overproduction of the hormone, resulting in high levels of calcium in the blood (hypercalcemia), which can cause a variety of health problems. Surgery is the most common treatment for primary hyperparathyroidism. Secondary hyperparathyroidism occurs as a result of another disease that initially causes low levels of calcium in the body and over time, increased parathyroid hormone levels occur.
The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.
A peritonsillar abscess forms in the tissues of the throat next to one of the tonsils. An abscess is a collection of pus that forms near an area of infected skin or other soft tissue. The abscess can cause pain, swelling, and, if severe, blockage of the throat. If the throat is blocked, swallowing, speaking, and even breathing become difficult. When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result. Peritonsillar abscesses are generally uncommon. When they do occur they are more likely among young adults, adolescents, and older children.
Though you might think of your spinal cord as one single piece, it's actually a column of nerves protected by a sheath of myelin and then further secured by 31 butterfly-shaped vertebrae (singular: vertebra). Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12.

Epilepsy surgery is reserved for people whose seizures are not well controlled by seizure medicines. This situation is sometimes called being "medically refractory" or "drug resistant." In children, the definition of medically refractory is even more individualized to the specific child's situation. Surgery may be considered for some children after weeks to months of treatment with seizure medicines.

In breech position, the baby's bottom is down. There are a few types of breech: Complete breech means the baby is bottom-first, with knees bent. Frank breech means the baby's legs are stretched up, with feet near the head. Footling breech means one leg is lowered over the mother's cervix. You are more likely to have a breech baby if you: Go into early labor Have an abnormally shaped uterus, fibroids, or too much amniotic fluid Have more than one baby in your womb Have placenta previa (when the placenta is on the lower part of the uterine wall, blocking the cervix)
When United Airlines decides their employees flying to Kentucky is more important than a doctor or any passenger who paid for their ticket it is time to STOP FLYING UNITED!!! Here are United employees dragging the man off the plane like a criminal.
This is a video which discusses the Vioptix tOX system of near infrared spectroscopy for the monitoring of free tissue transfer. Having information as to the health of the microvascular anastomosis is critical to improved patient outcome and free tissue survival. With better monitoring, supplementing clinical evaluation, surgeons are able to assess the health of the free tissue better and potentially improve patient outcome. The example in this video is of a free breast reconstruction where the tOX system was used to remotely monitor the free flap. The surgeon can follow the flap real time and more importantly follow trend lines to help predict flap complications.
TransMedicsโ proprietary Organ Care System (OCS) is the first commercial and portable warm blood perfusion organ transport system. With the OCS, doctors are able to perform โliving organ transplants,โ where organs are kept warm and functioning in a controlled environment from the time they are recovered to the moment they are placed in the recipientโs body.
A Pfannenstiel incision /หfษหnแตปnสtiหl/ is a type of abdominal surgical incision that allows access to the abdomen. It is used for gynecologic and orthopedics surgeries, and it is the most common method for performing Caesarian sections today.
Tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating an abdominal profile that is smoother and firmer. A flat and well-toned abdomen is something many of us strive for through exercise and weight control. Sometimes these methods cannot achieve our goals. Even individuals of otherwise normal body weight and proportion can develop an abdomen that protrudes or is loose and sagging. The most common causes of this include: Aging Heredity Pregnancy Prior surgery Significant fluctuations in weight What tummy tuck surgery can't do A tummy tuck is not a substitute for weight loss or an appropriate exercise program. Although the results of a tummy tuck are technically permanent, the positive outcome can be greatly diminished by significant fluctuations in your weight. For this reason, individuals who are planning substantial weight loss or women who may be considering future pregnancies would be advised to postpone a tummy tuck. A tummy tuck cannot correct stretch marks, although these may be removed or somewhat improved if they are located on the areas of excess skin that will be excised.
An abscess is a tender mass generally surrounded by a colored area from pink to deep red. Abscesses are often easy to feel by touching. The middle of an abscess is full of pus and debris. Painful and warm to touch, abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina(Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Inflammation around a hair follicle can also lead to the formation of an abscess, which is called a boil (furuncle). Unlike other infections, antibiotics alone will not usually cure an abscess. In general an abscess must open and drain in order for it to improve. Sometimes draining occurs on its own, but generally it must be opened by a doctor in a procedure called incision and drainage (I&D).
Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst may enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms. Syringomyelia has several possible causes, though the majority of cases are associated with a condition in which brain tissue protrudes into your spinal canal (Chiari malformation). Other causes of syringomyelia include spinal cord tumors, spinal cord injuries and damage caused by inflammation around your spinal cord. If syringomyelia isn't causing any problems, monitoring the condition may be all that's necessary. But if you're bothered by symptoms, you may need surgery.
Pregnancy occurs when an egg is fertilized by a sperm, grows inside a woman's uterus (womb), and develops into a baby. In humans, this process takes about 264 days from the date of fertilization of the egg, but the obstetrician will date the pregnancy from the first day of the last menstrual period (280 days 40 weeks).
Nephrotic syndrome is a kidney disorder that causes your body to excrete too much protein in your urine. Nephrotic syndrome is usually caused by damage to the clusters of small blood vessels in your kidneys that filter waste and excess water from your blood. Nephrotic syndrome causes swelling (edema), particularly in your feet and ankles, and increases the risk of other health problems. Treatment for nephrotic syndrome includes treating the underlying condition that's causing it and taking medications. Nephrotic syndrome can increase your risk of infections and blood clots. Your doctor may recommend medications and dietary changes to prevent these and other complications of nephrotic syndrome.
The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).
