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.

A nephron (from Greek νεφρός (nephros) meaning "kidney") is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.

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.

This is the CT of a 43 year old male patiënt with infected necrotizing pancreatitis that will undergo a VARD procedure; Videoscopic Assisted Retroperitoneal Debridment. Two weeks before this procedure two large bore percutaneous drains were placed in the peripancreatic collection. The patient i...s placed in supine position with the left side 30 degrees elevated. A 5-7 cm subcostal incision is made in the left flank. With help of CT images and by following the percutaneous drain, the subcutaneous tissue and the fascia are dissected and we enter the retroperitoneal peripancreatic collection. First, with a regular suction device any pus encountered is removed. Two long sympathectomy hooks are inserted in order to keep in the incision open. We than insert the zero degree laparoscope. The first necrosis encountered is removed under direct sight with the use of long grasping forceps. Following the percutaneous drain deeper into the cavity, parts of loosely adherent necrotic material are removed. Gently pulling we remove the necrotic tissue. The suction device is helpful in removing any fluid obstructing the view. Complete necrosectomy is not the ultimate aim of this procedure. Only loosely adherent pieces of necrosis are removed thereby keeping the risk of tearing underlying blood vessels to a minimum. In the rare case of extensive bleeding, the retroperitoneal cavity can be easily packed, either awaiting the bleeding to definitely stop or to act as a bridge to angiographic coiling. This patient is now 6 weeks after onset of disease. We always try to postpone surgical intervention, if possible up to 30 days. On the left side of the collection is the percutaneous drain. In this patient the drain had worked well for 2 weeks. When the patient deteriorated again it was decided to perform the VARD procedure. Large pieces of necrotic pancreas can be removed with VARD. This is a big advantage ov VARD over pure endosopic or percutaneous techniques. When all the necrotic tissue is removed we clean the cavity. Two drains are left in situ as a postoperative lavage system. The VARD procedure is performed via a 6 cm incision, which is closed and continuous postoperative lavage started immediately.

arteriovenous hemodialysis access has been the "gold standard" for patients needing hemodialysis for the past 30 years. Despite the reported advantages of autologous access, the availability of prosthetic graft material, coupled with the challenging dialysis candidate, has led to a trend of primary prosthetic graft dialysis access in the 1980s and 1990s. In recognition of this unfortunate trend, the National Kidney Foundation Dialysis Outcomes Quality Initiative (DOQI) used evidence from published studies and summary articles to generate clinical practice guidelines, emphasizing a shift back to autologous arteriovenous fistula (AVF) as the key to long-term successful hemodialysis.[1,2] These initial guidelines proposed a goal of 50% autologous AVF as the initial access, with a 40% prevalence of autologous access for a given practice or unit.

Hemophilia A, also called factor VIII (FVIII) deficiency or classic hemophilia, is a genetic disorder caused by missing or defective factor VIII, a clotting protein. Although it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous mutation, a change in a gene. According to the US Centers for Disease Control and Prevention, hemophilia occurs in approximately 1 in 5,000 live births. There are about 20,000 people with hemophilia in the US. All races and ethnic groups are affected. Hemophilia A is four times as common as hemophilia B while more than half of patients with hemophilia A have the severe form of hemophilia.

The abortion pill is a medicine called mifepristone that ends an early pregnancy.In general, it's used up to 70 days — 10 weeks — after the first day of a woman's last period. Patients over this mark can have an in-clinic abortion procedure.

Hemophilia B is a hereditary bleeding disorder caused by a lack of blood clotting factor IX. Without enough factor IX, the blood cannot clot properly to control bleeding.

This video: Blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.
