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.

Computed tomography (CT)-guided transthoracic needle biopsy is a well-established, minimally invasive diagnostic tool for pulmonary lesions. Few large studies have been conducted on the diagnostic performance and adequacy for molecular testing of transthoracic core needle biopsy (TCNB) for small pulmonary lesions.

Fulminant hepatic failure (FHF) or acute liver failure (ALF) is defined as the rapid development of acute liver injury with severe impairment of the synthetic function and hepatic encephalopathy in a patient without obvious, previous liver disease.

Pompe disease is a rare multisystem genetic disorder that is characterized by absence or deficiency of the lysosomal enzyme alpha-glucosidase (GAA). This enzyme is required to breakdown (metabolize) the complex carbohydrate glycogen and convert it into the simple sugar glucose.

Hemophilia B is a hereditary bleeding disorder caused by a lack of blood clotting factor IX. Without enough factor IX, the blood cannot clot properly to control bleeding.

PKU is inherited in families in an autosomal recessive pattern. Autosomal recessive inheritance means that a person has two copies of the gene that is altered. Usually, each parent of an individual who has PKU carries one copy of the altered gene. ... Gene alterations (mutations) in the PAH gene cause PKU.

A semen analysis, also called "seminogram" evaluates certain characteristics of a male's semen and the sperm contained therein. It is done to help evaluate male fertility, whether for those seeking pregnancy or verifying the success of vasectomy

Delayed puberty is defined as the absence of any signs suggestive of puberty by 14 years of age. In this case, the patient's pubertal delay appears to be constitutional because of his positive family history, absence of syndromic features or systemic illness, and bone age of 12 years. Puberty correlates more closely with bone age than chronological age. On follow-up, the patient will most likely demonstrate a similar onset of puberty as his father.

If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc.

Nearly 300 million people experience the world without certain colors every day. ‘Color For the Colorblind’ is a short documentary about what happened when we partnered with EnChroma, maker of color blindness-correcting glasses, to help people experience colors for the first time.

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.

A ureteroscopy is an examination or procedure using a ureteroscope. A ureteroscope, like a cystoscope, is an instrument for examining the inside of the urinary tract. The urologist can insert small instruments through the cystoscope to treat problems in the urethra and bladder or perform a biopsy. For a ureteroscopy, the urologist passes the ureteroscope through the bladder and into a ureter.

Pyogenic granuloma (lobular capillary hemangioma[1] ) is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown. Also see the Medscape Reference article Oral Pyogenic Granuloma. Pyogenic granulomas are misnamed; they are neither infectious nor granulomatous. The lesion usually occurs in children and young adults as a solitary, glistening red papule or nodule that is prone to bleeding and ulceration. Pyogenic granulomas typically evolve rapidly over a period of a few weeks, most often on the head, neck, extremities, and upper trunk. Pyogenic granuloma often arises in pregnancy (or rarely with oral contraceptive usage), particularly on the gingiva or elsewhere in the oral mucosa, and then is termed the "pregnancy tumor." Other pyogenic granuloma variants that have been well documented include the disseminated, subcutaneous, intravenous, and medication-induced (for example, retinoid, antiretroviral, and oncologic agent) subtypes. Removal of pyogenic granuloma is indicated to alleviate any bleeding, discomfort, cosmetic distress, and diagnostic uncertainty. A number of malignant tumors may clinically mimic pyogenic granuloma, making histopathologic confirmation important if the presentation is atypical. Aside from cutaneous and oral lesions, pyogenic granuloma has been reported throughout the gastrointestinal tract and upper airway, at various ocular locations, the central nervous system, the bladder, and the internal vasculature. This article discusses only cutaneous and oral involvement.

Before deciding how to treat one episode of high blood glucose, it is important to figure out why the number is high. Some possible causes include eating a heavy meal, not getting enough physical activity, forgetting to take diabetes medication, and dealing with illness and stress. Insulin is the medication that will bring blood glucose down the fastest. Someone who uses mealtime insulin can take correction doses to lower blood glucose. This requires a thorough understanding of when to inject, how often to give correction doses, and how much insulin to use. You will need to work with your doctor or diabetes educator to learn how to do this. Apart from administering insulin, the fastest way to lower your blood glucose is to engage in physical activity. Exercise results in an increased sensitivity to insulin. It causes your muscle cells to take up more glucose, leaving less of it to circulate in your bloodstream during and after the physical activity (which means a lower blood glucose when you test). Frequent, regular exercise is very important to good blood glucose control no matter what type of diabetes you have. Research has shown that it is vital in warding off long-term complications like neuropathy, retinopathy, and heart and kidney diseases. Don't forget to check with a doctor, though, before making any major changes to your exercise routine. And, if you have type 1 diabetes and your glucose is 250 mg/dl or higher, check for urine ketones. You should not exercise if ketones are present.

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.
