Summary
Retinoids, synthetic vitamin A derivatives, offer effective treatments for severe skin conditions like acne and psoriasis. While generally safe, their teratogenic nature limits use in women of childbearing potential.
Area of Science:
- Dermatology
- Pharmacology
- Oncology
Background:
- Vitamin A (retinol) has known therapeutic potential for skin diseases but is limited by toxicity.
- Development of synthetic retinoids offers safer alternatives for treating resistant dermatological conditions.
Purpose of the Study:
- To evaluate the efficacy of non-toxic synthetic retinoids in treating various skin diseases.
- To explore the potential antineoplastic effects of retinoids in epithelial cancers.
Main Methods:
- Clinical application of synthetic retinoids, specifically isotretinoin and etretinate.
- Observation of treatment outcomes in patients with acne, psoriasis, and other keratinization disorders.
- Investigation into the mechanisms of retinoid action on epidermal tissues and polyamines.
Main Results:
- Isotretinoin demonstrated high efficacy in cystic and conglobate acne.
- Etretinate proved useful in severe psoriasis and other keratinization disorders.
- Retinoids show potential for epithelial cancer prevention and treatment.
Conclusions:
- Synthetic retinoids provide effective therapeutic options for severe and resistant skin diseases.
- Retinoids modulate epidermal differentiation and proliferation, with polyamine influence a potential mechanism.
- Teratogenicity necessitates caution in prescribing retinoids to women of childbearing potential due to persistence in the body.

01:32The Retina
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
01:15Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
