Prompted by the hormone prolactin, the alveoli take proteins, sugars, and fat from your blood supply and make breast milk. A network of cells surrounding the alveoli squeeze the glands and push the milk out into the ductules, which lead to a bigger duct.
Retinitis pigmentosa is a rare, inherited degenerative eye disease that causes severe vision impairment. Symptoms often begin in childhood. They include decreased vision at night or in low light and loss of side vision (tunnel vision). There's no effective treatment for this condition. Wearing sunglasses may help protect remaining vision.
Compromise of the blood supply from microvascular disease, often in association with lack of sensation because of neuropathy, predisposes persons with diabetes mellitus to foot infections. These infections span the spectrum from simple, superficial cellulitis to chronic osteomyelitis. Diabetic foot infections typically take one of the following forms: Cellulitis Deep-skin and soft-tissue infections Acute osteomyelitis Chronic osteomyelitis Cellulitis Tender, erythematous, nonraised skin lesions are present, sometimes with lymphangitis Lymphangitis suggests group A streptococcal infection Bullae are typical of Staphylococcus aureus infection, but occasionally occur with group A streptococci
Recommended range without diabetes is 70 to 130mg/dL. (The standard for measuring blood glucose is "mg/dL" which means milligrams per deciliter.) If your blood glucose level is above 130mg/dL, that's fasting hyperglycemia. Fasting hyperglycemia is a common diabetes complication.
The peroneal artery is closely positioned to the fibula. The artery arises from the tibioperoneal trunk, distal to the takeoff of the anterior tibial artery (seen in the illustration below perforating the interosseous membrane). The peroneal artery sends perforators laterally to the skin of the lower leg, sometimes in a septocutaneous fashion via the lateral intermuscular septum, but often with muscular perforators. The length of the pedicle is usually short, but can be increased substantially by dissecting the peroneal artery and its venae from the fibula and using the distal bone for reconstruction.
A detailed discussion of the causes, diagnosis and management of the causes of Meningitis and Encephalitis. Includes bacterial, viral, fungal and autoimmune conditions as well as treatment of these conditions. Includes antivirals such as Aciclovir and Ganciclovir as well as IVIG and plasma exchange for autoimmune encephalitis.
Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it. The term "root canal" comes from cleaning of the canals inside a tooth's root. Decades ago, root canal treatments often were painful. With dental advances and local anesthetics, most people have little if any pain with a root canal. In fact, it's probably more painful living with a decayed tooth. Root canal alternatives include extracting the damaged tooth and replacing it with a dental implant, bridge or removable partial denture.
How Does a Bone Heal? All broken bones go through the same healing process. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury. The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone. Diagram of inflammation in a fractured bone Bone production begins when the clotted blood formed by inflammation is replaced with fibrous tissue and cartilage (known as soft callus). As healing progresses, the soft callus is replaced with hard bone (known as hard callus), which is visible on x-rays several weeks after the fracture. Bone remodeling, the final phase of bone healing, goes on for several months. In remodeling, bone continues to form and becomes compact, returning to its original shape. In addition, blood circulation in the area improves. Once adequate bone healing has occurred, weightbearing (such as standing or walking) encourages bone remodeling.
A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is called the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs.
2016 marks 10 years when illegal injections started to gain momentum and become a popular alternative to butt implants. The Brazilian butt lift wasn't well know at the time but the goal of finding an unlicensed person to inject a foreign substance into the body was in high demand.
The shoulder and arm receives its nerve supply through the brachial plexus. The brachial plexus is a complex network of nerves which come out of the neck, passes down to the front of the shoulder and then splits into many separate nerves to travel to different muscles and parts of the skin. Normally an arm movement is produced by initially thinking of the movement, then a message passes from the brain, down through the spinal cord to the appropriate nerve. Then the instruction to move is conveyed along the nerve to the specific arm muscle which then contracts and moves the arm.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness. In 1983 Joao Lobo Antunes, a Portuguese doctor, implanted a bionic eye in a person born blind.
Hypercalcemia is a condition in which the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with the way your heart and brain works. Hypercalcemia most commonly results from overactive parathyroid glands. These four tiny glands are each about the size of a grain of rice and are located on or near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and excessive use of calcium and vitamin D supplements. Signs and symptoms of hypercalcemia may range from nonexistent to severe. Treatment depends on the underlying cause.
