What to do if worsened potency
The introduction of topical steroids TS of varying potency have rendered the therapy of inflammatory cutaneous disorders more effective and less time-consuming. However the usefulness of these has become a double edged sword with constantly rising instances of abuse and misuse leading to serious local, systemic and psychological side effects. These side effects occur more with TS of higher potency and on particular areas of the body like face and genitalia. The article reviews the side effects of TS with special mention about peadiatric age group, also includes the measures for preventing the side effects.VIDEO ON THE TOPIC: How fentanyl is making the opioid epidemic even worse

A new neurobiological study has found that a synthetic form of THC, the active ingredient in cannabis, is an effective anti-depressant at low doses. However, at higher doses, the effect reverses itself and can actually worsen depression and other psychiatric conditions like psychosis. It has been known for many years that depletion of the neurotransmitter serotonin in the brain leads to depression, so SSRI-class anti-depressants like Prozac and Celexa work by enhancing the available concentration of serotonin in the brain.
However, this study offers the first evidence that cannabis can also increase serotonin, at least at lower doses. Laboratory animals were injected with the synthetic cannabinoid WIN55, and then tested with the Forced Swim test -- a test to measure "depression" in animals; the researchers observed an antidepressant effect of cannabinoids paralleled by an increased activity in the neurons that produce serotonin.
However, increasing the cannabinoid dose beyond a set point completely undid the benefits, said Dr. Gabriella Gobbi of McGill University.
So we actually demonstrated a double effect: At low doses it increases serotonin, but at higher doses the effect is devastating, completely reversed. The anti-depressant and intoxicating effects of cannabis are due to its chemical similarity to natural substances in the brain known as "endo-cannabinoids," which are released under conditions of high stress or pain, explained Dr.
They interact with the brain through structures called cannabinoid CB1 receptors. This study demonstrates for the first time that these receptors have a direct effect on the cells producing serotonin, which is a neurotransmitter that regulates the mood.
Gobbi and her colleagues were prompted to explore cannabis' potential as an anti-depressant through anecdotal clinical evidence, she said. And in the scientific literature, we had some evidence that people treated with cannabis for multiple sclerosis or AIDS showed a big improvement in mood disorders.
But there were no laboratory studies demonstrating the anti-depressant mechanism of action of cannabis. Because controlling the dosage of natural cannabis is difficult -- particularly when it is smoked in the form of marijuana joints -- there are perils associated with using it directly as an anti-depressant. Instead, she and her colleagues are focusing their research on a new class of drugs which enhance the effects of the brain's natural endo-cannabinoids.

This is especially true when it comes to your face, which is a sensitive and unique area of skin. In the United States, topical steroid creams are categorized by their potency, or how strong they are. Group 7 contains the least potent topical steroid creams, referred to as low potency. Only the lowest potency topical steroids should be used on your face.
Topical Steroids for Eczema
Topical steroids are medicated creams that are put on the skin. They are used in addition to moisturisers also called emollients for treating eczema. Topical steroids reduce skin inflammation. A short course will usually clear a flare-up of eczema. Side-effects are unlikely to occur with short courses. The terms eczema and dermatitis mean much the same.

Topical corticosteroids are one of the oldest and most useful treatments for dermatologic conditions. There are many topical steroids available, and they differ in potency and formulation. Although use of topical steroids is common, evidence of effectiveness exists only for select conditions, such as psoriasis, vitiligo, eczema, atopic dermatitis, phimosis, acute radiation dermatitis, and lichen sclerosus. Evidence is limited for use in melasma, chronic idiopathic urticaria, and alopecia areata.

Prescribing for the first time is a nerve-wracking experience. Of all the tasks performed by new doctors, it is probably the one with greatest direct impact on the wellbeing of patients. Safe and effective practice rests on a good understanding of both clinical pharmacology and practical prescribing. Acquiring this is not easy, particularly when faced with reams of information about hundreds of unfamiliar drugs, often presented in a way that appears detached from clinical reality.
