If you develop persistent fever or have a history of recurrent or chronic sinusitis or if you have sinus symptoms that don't improve or get worse, you should contact your doctor.However, seek medical care immediately if you develop Acute bronchitis in children also my include runny nose, fever, and chest pain.And if you’re a land snail, there’s one more step before you can inseminate each other. You might be tempted to think that “love dart” is some kind of euphemism. It is an actual sharp, spiky dart that they shoot at each other.Or more specifically, that one of the snails manages to shoot first in order to inject the other snail with spermicidal hormones so that their partner has fewer offspring. Unlike your typical dart, love darts aren’t shot through the air. Their little eye stalks can detect light and some movement, but they certainly can’t see well enough to aim a dart from any distance away.But the snails Lefty and Tomeu weren’t really digging Jeremy, and instead chose to mate with each other. This is good news for the biologists studying Jeremy, because all they really needed was for two left-spiraled snails to mate.It turns out that two lefty snails do not lefty-offspring make.
Now, alas, both of the potential mates who came to live with Jeremy have rejected him in favor of copiously reproducing with each other. See, Jeremy (and his lefty buddies) have a rare genetic condition called situs inversus, which is exactly what it sounds like.
Other experts say that sinus infections, although caused by bacteria and viruses, occur because the conditions in the individual's sinuses are optimal for infection.
Moreover, infection can be caused bacteria, viruses, or fungi that are already present in a person so that person-to-person transfer is not required for them to develop.
However, a "cure" is often a temporary condition in some people that either have chronic or recurrent sinus infections.
Bacterial sinus infections may benefit from antibiotic treatment (sometimes long-term antibiotic treatment is required before the patient is "cured" of a bacterial sinusitis), but there is no antibiotic treatment for viral sinusitis.
Pond snails fortunately don’t have to experience this pain, and instead make love in a far sweeter way: both partners get to play both roles and everyone ends up satisfied (or at least not stabbed).
