<p><strong>What Is Vaginitis?</strong></p>
<p>Vaginitis is a disorder of the vagina caused by infection or inflammation. It is often a result of infection by one of various microorganisms, but vaginitis may also be caused by irritation from soaps or medications, an allergic reaction, or hormonal changes.

A review article by Murali Rao and Julie Alderson in this month”s Current Psychiatry outlines four overlapping theories of depression. Let’s look at three of them:
Differences in neuron densities in various regions of the brain.
The effect of stress on neural growth and death.
Alterations in feedback pathways connecting the pre-frontal cortex to the limbic system.
The common denominator is what happens when the brain is exposed to chronic stress. Among other things, stress promotes the release of glucocorticoids. O...
