Bacterialvaginosis is a disease that's caused by the overgrowth of a type of bacteria that's called Gardnerella vaginalis, Gardnerella vaginalis. And as the name might suggest, this is the most common vaginal infection. Now I wanna put these really big quotes
around the term infection because the thing that's interesting about Gardnerella vaginalis is that it's a bacteriathat's naturally foundthe vagina. Now some may consider this to be a sexually transmitted infection, which is interestingbecause it doesn't cause
any problems until there'stoo much of it there. So when we look to the causes of bacterial vaginosis, they are all things that change the vaginal environment. That can include acts like douching, so douching, or rinsing of the vagina. The other is having newor multiple sex partners.
And finally, another known cause is the use of antibiotics. This could bethe case of somebody that has a throat infection or a pneumonia that's on antibiotics which will then attackthe bacteria that exists within the vagina andallow Gardnerella vaginalis to overgrow and cause bacterial vaginosis.
So we've touched a little bit on it here, but I wanna aw it out. So when we talk about the pathophysiology of a disease, we'retalking about the mechanism by which that disease occurs. Soorder to understandthe pathophysiology of bacterial vaginosis, we need to take a look at a sample of bacteria
that existsthe vagina. So I'll aw out someGardnerella vaginalis bacteria, and so I'll put this upour key. This is the symbol forGardnerella vaginalis. And I'll aw a few of them around here, but I also wanna show that there are a lot of other bacteriathat existthis sample. So if you really look at it here,
DermTV The Difference Between Canker Sores and Herpes DermTV Epi 103
Hello, I'm Neal Schultz pause and welcome to DermTV. When we get sores inside our mouth or on ourlips, usually they're very painful. And almost all of them are causedby one of two thingsâ€”either a herpes virus outbreak or canker sores, andI find that not only do most people get them confused, but can you believethis, most s get them confused also. So let's talk about it.
Canker sores are not contagious. They'revery painful, especially when you're eating and food touches the areawhere you have the canker sore. Canker sores occur almost exclusively insideyou mouth, not outside, not on your outer lip, and not on your chin. Andwhen they occur inside your mouth, which can be on this part of the skinor seen inside the cheeks, you see a gray or tan, round area with a brightred rim right around it. They go awaya couple of days and they'reeasily treated with topical antibiotics. Usually, we take tetracycline,open a capsule, put ita
little glass of water, and take just a pieceof cotton, dip itthat water, and hold it against the canker sorefor a few minutes and, after 2 of 3 days, it will go away. This is very,very different from herpes outbreaks. Herpes outbreaks usually are notthat painful although right before you get them, you feel a tingling ora burningthe skin where you're going to get the outbreak. They arevery contagious. They usually don't occur inside your mouth, they occuroutside your mouth. They can be right on the lip, on the edge of the lip,or around the mouth, or really
any place on your face. And when they happen,usually they occur with blisters, and those blisters are often clusteredtogether and with a red ear around it but not a red, sharp rim likeyou see with a canker sore. Over a period of a couple of days, they yand crust and scab. They're very easy to treat. They're treated withoral mediion, oral mediion for only a day may become not contagious bythe second or third day. If you're getting sore inside your mouth oraround your mouth or on your lips, and you're not sure what it is and you don'tknow how to treat it, see your
dermatologist who can give you some medicineto make sure that the sores go away faster and you become comfortable muchsooner.
