Condoms: Facts you should know
Condoms: Facts you should know Alicia Berger 4,163 Views • 3 years ago

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.

Priapism
Priapism samer kareem 4,160 Views • 3 years ago

Priapism is a prolonged erection of the penis. The persistent erection continues hours beyond or isn't caused by sexual stimulation. Priapism is usually painful. Although priapism is an uncommon condition overall, it occurs commonly in certain groups, such as people who have sickle cell anemia. Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction). Priapism is most common in men in their 30s.

New flu vaccines are released every year to keep up with rapidly adapting flu viruses. Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. After vaccination, your immune system produces antibodies that will protect you from the vaccine viruses.

Pyogenic Granuloma Surgery
Pyogenic Granuloma Surgery samer kareem 4,139 Views • 3 years ago

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.

ALPHA & BETA BLOCKERS
ALPHA & BETA BLOCKERS samer kareem 4,136 Views • 3 years ago

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.

Lower High Blood Sugar
Lower High Blood Sugar samer kareem 4,135 Views • 3 years ago

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.
