De Quervain's tenosynovitis (dih-kwer-VAINS ten-oh-sine-oh-VIE-tis) is a painful condition affecting the tendons on the thumb side of your wrist. If you have de Quervain's tenosynovitis, it will probably hurt when you turn your wrist, grasp anything or make a fist. Although the exact cause of de Quervain's tenosynovitis isn't known, any activity that relies on repetitive hand or wrist movement — such as working in the garden, playing golf or racket sports, or lifting your baby — can make it worse.

Before ovulation occurs, the average diameter of the dominant follicle is 22 to 24 mm (range 18-36 mm). It is the only marker that can predict ovulation with ease. * In stimulated cycle (hormonal treatment), generally, all or most of the antral follicles grow. The growth rate will be different for each of them.
Tracheotomy is a surgical procedure which consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole), or tracheostomy, can serve independently as an airway or as a site for a tracheostomy tube to be inserted; this tube allows a person to breathe without the use of his or her nose or mouth. Both surgical and percutaneous techniques are widely used in current surgical practice. It is among the oldest described procedures.
The complex circuitry interconnecting different areas in the brain, known collectively as white matter, is composed of millions of axons organized into fascicles and bundles. Upon macroscopic examination of sections of the brain, it is difficult to discern the orientation of the fibers. The same is true for conventional imaging modalities. However, recent advancements in magnetic resonance imaging (MRI) make such task possible in a live subject. By sensitizing an otherwise typical MRI sequence to the diffusion of water molecules it is possible to measure their diffusion coefficient in a given direction1. Normally, the axonal membrane and myelin sheaths pose barriers to the movement of water molecules and, thus, they diffuse preferentially along the axon2. Therefore, the direction of white matter bundles can be elucidated by determining the principal diffusivity of water. The three-dimensional representation of the diffusion coefficient can be given by a tensor and its mathematical decomposition provides the direction of the tracts3; this MRI technique is known as diffusion tensor imaging (DTI). By connecting the information acquired with DTI, three-dimensional depictions of white matter fascicles are obtained4. The virtual dissection of white matter bundles is rapidly becoming a valuable tool in clinical research.
Our journey begins with a transverse section of tightly packed axons as seen through light microscopy. Although represented as a two-dimensional "slice", we see that these axons in fact resemble tubes. A simulation of water molecules diffusing randomly inside the axons demonstrates how the membranes and myelin hinder their movement across them and shows the preferred diffusion direction --along the axons. The tracts depicted through DTI slowly blend in and we ride along with them. As we zoom out even more, we realize that it is a portion of the corpus callosum connecting the two sides of the brain we were traveling on and the great difference in relative scale of the individual axons becomes evident. The surface of the brain is then shown, as well as the rest of the white matter bundles--a big, apparently chaotic tangle of wires. Finally, the skin covers the brain.
With the exception of the simulated water molecules, all the data presented in the animation is obtained through microscopy and MRI. Computer algorithms for the extraction of the cerebral structures and a custom-built graphics engine make our journey through the brain's anatomy possible in a living person.

This is the incredible moment a new-born baby arrived still inside its amniotic sac, completely intact. The tiny infant can be seen moving and stretching still inside the sac, as medics prepare to snip the new born free. The amniotic sac is a thin but durable membrane filled with fluid which helps keep a baby warm and safe from bumps during pregnancy. When it breaks, this is typically referred to as a woman's 'waters breaking' shortly before she gives birth. But in rare cases, less than 1-in-80,000 births, the baby is delivered with the membranes still intact and this is known as a 'caul birth'. Some babies are born with part of the membrane still attached to them, but to be born completely encased in the intact membrane is incredibly rare. Many people still believe the phenomenon to be a good omen for the child's infancy and it is has even been suggested, but not proven, that caul babies will always have a natural affinity for water. The video was taken in Spain on Saturday and captures the rare moment the baby was born with the membrane covering its entire body, just minutes after its twin was delivered normally.
Femoroacetabular impingement (FAI) is a condition in which extra bone grows along one or both of the bones that form the hip joint — giving the bones an irregular shape. Because they do not fit together perfectly, the bones rub against each other during movement. Over time this friction can damage the joint, causing pain and limiting activity.
Today, hair transplant physicians are able to make use of different techniques to extract and transplant large numbers of hair follicles (follicular units). There are two primary techniques for hair transplantation currently in use. The FUE (Follicular Unit Extraction) and the FUT (Follicular Unit Transplantation) methods. They differ primarily in the way hair follicles are extracted from the donor area. Follicular Unit Transplantation (FUT) The FUT process involves removing a small strip of tissue from the back of the head, from which the donor hair follicles will be extracted. The hair follicles are harvested from the strip by a skilled clinical team before being individually transplanted to the recipient areas. In most cases, and especially cases of advanced hair loss, FUT is the preferred method because it allows the physician to fully utilize the scalp area to deliver results consistent with patient expectations. FUT typically allows for the greatest number of grafts to be transplanted in a single session. Pain Management Some patients report higher levels of discomfort with FUT procedures compared to FUE due the potential swelling in the area where the strip of tissue was removed, but both methods have a very manageable recovery period and pain medication can be prescribed by your physician if needed. Both techniques of hair transplantation are relatively simple. Hair transplantation procedures are outpatient surgeries with some patients going back to work as soon as the very next day. Scarring The FUT strip extraction method typically results in a very narrow linear scar in the back of the head (typically 1mm in diameter or less in size). Since the scar is very thin, it’s easily concealed by all but the shortest of haircut styles. A short to moderate crop setting on most clippers is sufficient to conceal the scar for the majority of patients, and over time the scar will become less noticeable as it fades. Costs The industry norm for pricing is on a per-graft basis. This allows each individual to pay for only what they need and receive in number of grafts, and not a flat rate that in the end may cost you more. The per-graft cost of a FUT procedure is generally lower than that of a FUE procedure. Lately however, in response to the rising popularity of the FUE technique, many hair transplantation clinics have started lowering the per graft cost on FUE procedures, so that the cost difference between the two types of procedure are not as much as most people think. The costs of medical procedures always vary by patients’ conditions, needs and objectives. For the most accurate assessment of your hair loss and the associated cost of your hair restoration, you will need to speak to a physician. Follicular Unit Extraction (FUE) In an FUE hair transplantation, each follicular unit is individually taken directly from the scalp with no strip of tissue being removed. Hair follicles are removed in a random fashion and the result is less density in the donor area that many say is not even noticeable. This is the main difference between FUE & FUT. Since follicles are removed one at a time, fewer follicles can be harvested during a typical session, making FUE a better option to restore hair in smaller cases (number of grafts) compared to the traditional FUT method. FUE is constantly evolving and what was once utilized for only smaller cases is now being utilized for larger and larger cases. Some people that prefer the FUE method may have the option of splitting their procedure into two days in order to complete their recommended transplantation goals. Pain Management With no stitches required and no linear scar left to heal, FUE procedures do have a faster healing time and less post-procedure discomfort compared to the traditional FUT procedure. Scarring Since FUE procedures involve removing hairs individually from the scalp, there is no linear scar left behind. However, there will be tiny 1mm in diameter or less puncture marks that tend to heal by themselves after scabbing-over in the days following the procedure. These tiny wounds typically heal within three to seven days. Costs Since the physician must remove each hair follicle individually, the time-sensitive nature of an FUE procedure typically makes it more expensive than an FUT procedure. As stated earlier, FUE technology is improving as well as gaining popularity and many hair restoration practices (including Bosley) have started to lower the cost per graft price for FUE procedures. Nowadays, the cost difference between a FUE and a FUT procedures is less disparate.
Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12. In the body, phenylalanine hydroxylase converts the amino acid phenylalanine to tyrosine, another amino acid.

You are most fertile at the time of ovulation, (when an egg is released from your ovaries) which usually occurs 12-14 days before your next period starts. This is the time of the month when you are most likely to get pregnant. It is unlikely that you will get pregnant just after your period, although it can happen.
Orthopedic spine surgeons and vascular surgeons at UW Health in Madison, WI work together to perform minimally invasive anterior lumbar interbody fusion (Mini-ALIF). With this type of spinal fusion surgery, patients have smaller incisions, usually spend less time in the hospital and typically return to daily activities more quickly.

Guillain-Barre syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your extremities are usually the first symptoms. These sensations can quickly spread, eventually paralyzing your whole body. In its most severe form Guillain-Barre syndrome is a medical emergency. Most people with the condition must be hospitalized to receive treatment. The exact cause of Guillain-Barre syndrome is unknown. But it is often preceded by an infectious illness such as a respiratory infection or the stomach flu. There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Most people recover from Guillain-Barre syndrome, though some may experience lingering effects from it, such as weakness, numbness or fatigue.
Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental illnesses. It often works when other treatments are unsuccessful. Much of the stigma attached to ECT is based on early treatments in which high doses of electricity were administered without anesthesia, leading to memory loss, fractured bones and other serious side effects. ECT is much safer today. Although ECT still causes some side effects, it now uses electric currents given in a controlled setting to achieve the most benefit with the fewest possible risks.
