Conclusion: oral minoxidil, finasteride, dutasteride), and procedural (e.g. platelet-rich plasma, fractionated lasers, hair transplantation) treatments successfully promote hair growth, highlighting the superiority of a multifaceted and individualized approach to management.
PubMed 38852607 ↗Conclusion: Although topical KTZ is safe, clinicians should be aware that allergic contact dermatitis may occur. Further studies should be completed to investigate the use of topical KTZ for hair loss and inflammatory dermatoses.

PubMed 31858672 ↗Conclusion: We suggest using the term 'drug-induced intracranial hypertension' (DIIH) and propose a set of diagnostic criteria for DIIH. Our review attempts to identify DIIH-associated drugs based on a strict diagnostic and drug-causality algorithm, then stratify them into appropriate risks categories. This may ultimately assist physicians in counselling patients about the risk of DIIH when prescribing medications and recognizing this uncommon yet sight-threatening condition.
