A myringotomy is a procedure in which your doctor creates a small hole in the eardrum so fluids such as water, blood, or pus can drain out. In many cases, your doctor will put in a tube so it won't get backed up again. The tube, which will usually fall out on its own in about six to 18 months, lets air flow through and keeps the middle ear dry. Tubes also: Reduce pain Improve hearing Cut down on the number of infections your child may have
The cardiac cycle is the sequence of events that occurs when the heart beats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood
It used to be when a woman needed a hysterectomy she could expect full abdominal surgery with a long recovery time. Dr. Melissa Lee uses less invasive methods that can cut the patients downtime in half.
"We were trained in more laparoscopic and minimally invasive cases so of course that's what I'm more comfortable with doing right now."
She sees a new generation of patients opting for laparoscopic surgery.
"Laparoscopy is the use of small cameras with small incisions and instruments that are guided by the hand, and you're able to see directly into the abdomen without actually fully opening the abdomen," says Dr. Lee, an obstetrician-gynecologist with Lee Memorial Health System.
Nowadays, even a large mass or uterus can be removed using the slender tools.
"There are multiple different laparoscopic instruments that you can use. Whether they're blunt dissections or just dissectors that hold and retract back or actual scissors or cutting instruments, there are multiple different options," says Dr. Lee.
While a standard abdominal hysterectomy requires a four to eight inch incision, the laparoscope needs only a quarter to half inch. It's enough to make a big difference in terms of recovery.
"They're able to get up and move around faster. They're able to recover faster, their pain level and their need for pain medicine is much lower," says Dr. Lee.
The laparoscopic procedure also cuts down on scarring and more importantly, shortens the hospital stay. The trend now is home within 24 hours.
"Where the patient is done early in the morning, they're doing well they're tolerating oral intake they're able to getup and move around. And those patients a lot of times will feel comfortable to go home that same nigh after a major surgery," says Dr. Lee.
New studies show women who've had a laparoscopic hysterectomy viewed their quality of life as better than those who had an open abdominal procedure, making this a good option for the right patient.

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.
Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen. Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis
Are most spiders poisonous? The majority of the 3,000 spiders in the United States aren’t poisonous. Even if most spiders did bite, their fangs are too small or weak to puncture human skin.

A peritonsillar abscess forms in the tissues of the throat next to one of the tonsils. An abscess is a collection of pus that forms near an area of infected skin or other soft tissue. The abscess can cause pain, swelling, and, if severe, blockage of the throat. If the throat is blocked, swallowing, speaking, and even breathing become difficult. When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result. Peritonsillar abscesses are generally uncommon. When they do occur they are more likely among young adults, adolescents, and older children.
