Spinal anesthesia is done in a similar way. But the anesthetic medicine is injected using a much smaller needle, directly into the cerebrospinal fluid that surrounds the spinal cord. The area where the needle will be inserted is first numbed with a local anesthetic. Then the needle is guided into the spinal canal, and the anesthetic is injected. This is usually done without the use of a catheter. Spinal anesthesia numbs the body below and sometimes above the site of the injection. The person may not be able to move his or her legs until the anesthetic wears off.

Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small (at 6 weeks gestation, the baby is only 5-9mm long) and a transvaginal ultrasound may be required to get a better image of the baby. Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.

Only about a third of people with lupus get the tell-tale butterfly-shaped rash on their face. What you should know:

Experience with endoscopic retrograde cholangiopancreatography (ERCP) in children has been limited due to multiple factors, including the relatively low incidence of diseases requiring ERCP in this age group, the impression that the procedure is technically difficult in children, and because the indications and safety of ERCP in children have not been well defined. As a result, patients are generally referred to a tertiary care facility or to adult endoscopists who perform a high volume of procedures.

An abdominal hysterectomy is a surgical procedure that removes your uterus through an incision in your lower abdomen. Your uterus — or womb — is where a baby grows if you're pregnant. A partial hysterectomy removes just the uterus, leaving the cervix intact. A total hysterectomy removes the uterus and the cervix. Sometimes a hysterectomy includes removal of one or both ovaries and fallopian tubes, a procedure called a total hysterectomy with salpingo-oophorectomy (sal-ping-go-o-of-uh-REK-tuh-me). A hysterectomy can also be performed through an incision in the vagina (vaginal hysterectomy) or by a laparoscopic or robotic surgical approach — which uses long, thin instruments passed through small abdominal incisions.

A tapeworm is a ribbon-shaped parasite that lives in human or animal intestines. They are uncommon in developed countries. There are a number of different types which all have slightly different life cycles. Tapeworm infection can come from animals such as pigs, sheep, cattle, fish, dogs and cats. Eating undercooked food contaminated with tapeworm cysts and eggs causes the infection. Tapeworm eggs are shed in stools and it is possible for infection to spread from person to person through the oral/anal route.

A craniotomy involves making an incision in the scalp and creating a hole known as a bone flap in the skull. The hole and incision are made near the area of the brain being treated. During open brain surgery, your surgeon may opt to: remove tumors. clip off an aneurysm

Letting children patients play the role of a dentist may be a good way to introduce them to the different types of instruments used in a dental clinic. This in turn may also reduce thier anxiety or fear of the dentist and make them more easy-going and compliant towards dental treatments. Ofcourse instruments should be clean and steril and care should be taken to not give them pointed or sharp objects.

Beta-blockers, also known as beta antagonists, beta-adrenergic blocking agents, or beta-adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, migraine, glaucoma, and overactive thyroid symptoms.

Intra-abdominal abscess continues to be an important and serious problem in surgical practice. Appropriate treatment is often delayed because of the obscure nature of many conditions resulting in abscess formation, which can make diagnosis and localization difficult. Associated pathophysiologic effects may become life threatening or lead to extended periods of morbidity with prolonged hospitalization. Delayed diagnosis and treatment can also lead to increased mortality; therefore, the economic impact of delaying treatment is significant.

Retro-sigmoid craniotomy (often called "keyhole" craniotomy) is a minimally-invasive surgical procedure performed to remove brain tumors. This procedure allows for the removal of skull base tumors through a small incision behind the ear, providing access to the cerebellum and brainstem. Neurosurgeons may use this approach to reach certain tumors, such as meningiomas and acoustic neuromas (vestibular schwannomas).

Shigellosis is a diarrheal disease caused by a group of bacteria called Shigella. Shigella causes about 500,000 cases of diarrhea in the United States annually 1. There are four different species of Shigella:

Acanthamoeba keratitis is a rare disease in which amoebae invade the cornea of the eye. It may result in permanent visual impairment or blindness.

Scoliosis (pronounced sko-lee-o-sis) is a three-dimensional deformity that occurs when the spine becomes abnormally rotated and curved sideways. Most often this deformity has no known cause, in which case it is called idiopathic scoliosis. While the cause is unknown, idiopathic scoliosis does tend to run in families. The specific genes involved have not all been identified yet, and there could be factors beyond genetics as well

Skin grafting is a surgical procedure that involves removing the skin from one area of the body and moving it, or transplanting it, to a different area of the body. This surgery may be done if a part of your body has lost its protective covering of skin due to burns, injury, or illness. Skin grafts are performed in a hospital. Most skin grafts are done using general anesthesia, which means you’ll be asleep throughout the procedure and won’t feel any pain.

Most cataracts are associated with the aging process and are common among older Americans. In fact, according to the National Eye Institute (NEI), 68.3 percent of Americans 80 and older had cataracts in 2010. And the prevalence of cataracts in the U.S. is expected to grow significantly in the years ahead, due in part to the aging of the population. In 2010, roughly 24.4 million Americans had cataracts, and that number is projected to grow to 50.2 million by the year 2050, according to NEI.
