In this study, sublingual tofacitinib achieved a longer estimated half-life than oral administration in treatment-resistant alopecia areata patients, potentially supporting daily dosing; overall treatment response was modest.

The study reported that reducing finasteride particle size significantly improved its cellular permeation through prostate epithelial cells, though it had a lesser impact on systemic pharmacokinetics and tissue distribution in rats.

In this study, gene expression changes in rat whisker follicles after methamphetamine administration may serve as indicators of the drug's rewarding effects and potential addiction pathways.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

This study analyzed pexidartinib-associated adverse events from FDA data and reported common events such as hepatic issues and systemic reactions. It highlighted sex-specific susceptibilities and reinforced the need for risk mitigation and long-term monitoring in tenosynovial giant cell tumor management.

This review discusses current and emerging treatments for alopecia areata, emphasizing systemic treatments for moderate to severe cases, and reports no new clinical results.

This case report describes a Persian cat with Acute Moist Dermatitis triggered by ectoparasite infestation and complicated by systemic infection, which required intensive treatment including antiparasitics and antibiotics.

This review discusses post-finasteride syndrome, highlighting occasional adverse sexual and systemic effects in men and women, but reports no new research findings while emphasizing the need for better education about the drug's risks.

This study reported that BRL 7660 significantly reduced sebum secretion and acne symptoms in human studies with topical administration, but the placebo effect and commercial pressures halted further investigations.

This study found that topical fluridil increased the anagen percentage in men with androgenetic alopecia without causing irritation or systemic side effects.

This article discusses psoriasis, highlighting its common triggers, such as trauma and infections, and potential treatment options ranging from topical therapies to systemic medications like methotrexate for severe cases.

In this study, otitis externa in toy poodles and miniature dachshunds was successfully treated using a video otoscope alongside systemic antibiotics and antifungals, with all dogs recovering fully.

This study found that high-dose oral zinc significantly influences hair growth in mice, showing both inhibition and promotion effects depending on the timing and duration of administration.

This study found that long-term use of 5α-reductase inhibitors is associated with improved overall survival in men with renal cell carcinoma, particularly those with low comorbidity not receiving surgery or systemic therapy, suggesting a potential role for androgen modulation in disease management.

This study reports how the Polish-American Medical Society (ZLP Chicago) played a proactive role during the COVID-19 pandemic in the Chicago area, leading efforts in public education, support for administrative measures, and dissemination of health guidelines to the Polish community.

This research explores innovative methods to enhance drug delivery to the brain, including techniques like focal intra-arterial administration and temporary blood-brain barrier opening, aimed at improving treatment for brain disorders, the authors report.

This research reported that squarticles, nanoparticles made from sebum-derived lipids, enhanced the follicular delivery and skin accumulation of diphencyprone and minoxidil, indicating effective drug deposition with reduced systemic absorption in alopecia treatment.

This review found little evidence supporting zinc as a first-line treatment for dermatological conditions, except in cases of systemic zinc deficiency, and suggests further research is needed.

This review discusses the complexity of neuroactive steroid therapies for neuroprotection and reports no new clinical findings, suggesting potential unexpected effects in the brain compared to systemic levels.

In this study of seven randomized clinical trials, JAK inhibitors were associated with improved hair regrowth outcomes in alopecia areata patients compared to placebo, with oral administration being more effective than external application, though longer trials are needed to confirm safety and effectiveness.

This review discusses the use of topical and oral minoxidil for pediatric hair disorders, pointing out the lack of guidelines and the potential risks associated with systemic absorption, but reports no clinical results.

In this animal study, topical diazoxide treatment led to increased hair thickness and follicle growth in bald stumptailed macaques without causing notable systemic side effects.

This article reviews the causes of hair loss in pediatric and adult populations, emphasizing the importance of distinguishing between primary dermatologic conditions and those related to systemic diseases, but reports no new clinical findings.

This study explored using a chitosan oligomer coating for topical delivery of dutasteride-loaded nanostructured lipid carriers, aiming to reduce systemic exposure and cytotoxicity.

This study found that cortexolone 17α-propionate showed strong topical antiandrogenic activity, outperforming progesterone and several known antiandrogens, but lacked systemic antiandrogenic effects in animal models.

In this study, using a novel topical androgen receptor suppressor, fluridil, significantly increased the percentage of growing hairs in males with androgenetic alopecia without systemic absorption or adverse side effects.

In this study, itraconazole was shown to accumulate in the deeper skin layers of guinea pigs after oral administration, suggesting this delivery method effectively targets infective organisms there.

This review study found that vesicular carriers like liposomes, niosomes, invasomes, and transferosomes can enhance drug penetration through follicles, benefiting treatments for alopecia, acne, and infections, as well as potentially facilitating systemic delivery of antihypertensive drugs and insulin.

This source discusses the potential of topical JAK inhibitors, like tofacitinib, as effective treatments for autoimmune skin diseases, emphasizing their superior safety profile and minimal adverse effects compared to conventional systemic therapies.

This review highlights novel drug delivery systems for alopecia that enhance localization in the pilosebaceous unit, reduce systemic exposure, and support sustained drug release, with a focus on optimized follicular carriers ranging from 100-300 nm for improved drug residence compared to conventional methods.
