Most of us have taken a sex education class or two. We know what condoms are supposed to be used for. Whether or not people use condoms every time they are necessary is a totally different story. You were probably taught the necessary but embarrassing lesson of how to put a condom on by the visual aids your sex education teacher provided. Of course, these tactics are a little more modern, so depending on how old you are, you may not have learned the basics of condom use until after high school. Yes, condoms are a pretty smart invention and they’re pretty safe to use. They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners. However, with all the things we know about condoms, there’s still so much we don’t know. Here are 10 facts about condoms that are just as interesting as the condoms themselves.
A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done.

hemothorax is most often defined as rapid accumulation of ≥ 1000 mL of blood. Shock is common. Patients with large hemorrhage volume are often dyspneic and have decreased breath sounds and dullness to percussion (often difficult to appreciate during initial evaluation of patients with multiple injuries).
Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.
How do you assess cerebellar function? Ask them to do this as fast as possible while you slowly move your finger. Repeat the test with the other hand. Perform the heel-to-shin test. Have the patient lying down for this and get them to run the heel of one foot down the shin of the other leg, and then to bring the heel back up to the knee and start again.
Rheum is made up of mucus, skin cells, oils and dust. The rheum that comes from the eyes and forms eye boogers is called gound, which you may know as eye sand, eye gunk, sleep dust, sleep sand, sleep in your eyes, or eye shnooters. When you're awake, gound doesn't cause any problems.
A pneumothorax can be caused by a blunt or penetrating chest injury, certain medical procedures, or damage from underlying lung disease. Or it may occur for no obvious reason. Symptoms usually include sudden chest pain and shortness of breath. On some occasions, a collapsed lung can be a life-threatening event.
Cholecystectomy means removal of the gallbladder. The most common reasons
your doctor might recommend a cholecystectomy are biliary colic, cholecystitis,
choledocolithiasis, or gallstone pancreatitis. Biliary colic, also known as symptomatic
cholelithiasis, is caused by gallstones, which are hardened deposits of bile. Gallstones are
common in the general population, and gallstones alone are not a reason for gallbladder
removal if they do not cause symptoms. However, sometimes gallstones can get caught at the
neck of the gallbladder, causing pain when the gallbladder contracts against them trying to
release its bile, especially after a fatty meal. With biliary colic, the pain typically resolves within
an hour or so. Occasionally, a stone or some other blockage may prevent the gallbladder from
emptying over a long period of time, causing an increase in pressure and trapped fluid within the
gallbladder. This can cause inflammation and infection of the gallbladder, which we call
cholecystitis. Choledocholithiasis is when there are one or more stones in the bile ducts, which
can cause back up of bile into the liver, and depending on the location of the stones, could
cause pancreatitis, which is inflammation of the pancreas. Other reasons for gallbladder
removal, though less common, are gallbladder polyps and cancer. All of these are reasons for
gallbladder removal.
Pain in the affected bone is the most common complaint of patients with bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used (for example, leg pain when walking). As the cancer grows, the pain will be there all the time. The pain increases with activity and the person might limp if a leg is involved.
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).
Experts do not know the exact cause of Zollinger-Ellison syndrome. About 25 to 30 percent of gastrinomas are caused by an inherited genetic disorder called multiple endocrine neoplasia type 1 (MEN1). MEN1 causes hormone-releasing tumors in the endocrine glands and the duodenum.
A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child's having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity. Febrile seizures represent a unique response of a child's brain to fever, usually the first day of a fever. Fortunately, they're usually harmless and typically don't indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.
