Summary
Topical isotretinoin shows promise as a new skincare treatment, potentially offering better tolerability and stability than existing options. Further research is needed to fully understand its long-term effects and safety profile.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Topical retinoids are common dermatologic treatments.
- Topical isotretinoin is being investigated as an alternative.
- Challenges include limited research, formulation issues, and regulatory hurdles.
Purpose of the Study:
- To explore the potential of topical isotretinoin as a dermatologic treatment.
- To compare its efficacy and tolerability with existing topical retinoids.
- To identify its potential benefits, such as formulation stability and use in combination therapies.
Main Methods:
- Review of existing literature on topical isotretinoin.
- Analysis of formulation challenges and regulatory considerations.
- Assessment of potential clinical utility and comparison with other topical retinoids.
Main Results:
- Topical isotretinoin demonstrates similar performance to other topical retinoids.
- Potential benefits include improved tolerability and enhanced formulation stability.
- It may be suitable for integration into combination therapies.
Conclusions:
- Topical isotretinoin presents a promising therapeutic option in dermatology.
- Further randomized controlled trials are essential to establish optimal use, long-term effects, and safety.
- Its potential to broaden treatment choices warrants continued investigation.

01:19Clinical Applications of Epidermal Stem Cells
3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:14Changes in Skin Color: Clinical Perspectives
3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:16Drug Delivery: Overview
724
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
