There is nothing that compares to the fresh-faced feeling you have when you leave the aesthetician after a facial. There is just something so freeing about knowing that nasty little buggers like blackheads, whiteheads and all other kinds of heads have been given the heave-ho. That could be why this Facebook video of a blackhead being removed has gone viral. With more than 24 million views, the popular video is weirdly difficult to stop watching.

Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

A cervical herniated disc may be treated by removing part of the disc through a small incision (microdiscectomy). If this is done from the back (posteriorly) rather than from the front of the neck, a spinal fusion is not necessary. The alternative is an anterior cervical discectomy and fusion procedure.

A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Cerebral hydatid disease (neurohydatidosis) is caused by Echinococcus granulosus or less commonly E. alveolaris or E. multilocularis. The larval stage is the cause of hydatid disease in humans 1. Epidemiology Cerebral hydatid disease is a rare parasitic infestation and accounts for 1-2 % of all cystic echinococcosis. Hydatid disease is endemic in the Mediterranean region, the Middle East, Africa, eastern part of Turkey, Australia and parts of South America 2. Clinical presentation Symptoms and signs include: focal neurological deficits headaches increased intracranial pressure hydrocephalus papilloedema and loss of vision altered mental status seizures (rare)

The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body's tissues. With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells.

People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.

The primary goal of treatment for each patient is to help relieve pain and other symptoms resulting from the herniated disc. To achieve this goal, each patient’s treatment plan should be individualized based on the source of the pain, the severity of pain and the specific symptoms that the patient exhibits.
