Real-time LC-OCT monitoring of scalp hypertrophic actinic keratosis clearance following cryotherapy, laser, and 5-fluorouracil therapy. (PubMed, Front Med (Lausanne)) - "To characterize LC-OCT response patterns in scalp hAKs treated with ablative CO2 laser, cryotherapy, or topical 0.5% 5-fluorouracil/10% salicylic acid, and to evaluate the potential role of LC-OCT in identifying persistent imaging features suggestive of incomplete treatment response requiring retreatment or treatment escalation. Topical 5-FU/SA showed heterogeneous responses; 65% of lesions, mainly KIN 3/PRO III, required escalation to a physical modality. LC-OCT enables non-invasive monitoring of treatment-related hAKs modifications and may identify persistent imaging abnormalities despite apparent clinical resolution, supporting individualized sequential treatment strategies."

Remission of a large plantar verruca vulgaris in an immunocompromised patient postincisional punch biopsy (BAD 2023) - "His immunosuppressive treatment consists of tacrolimus, mycophenolate mofetil and prednisolone 5 mg once daily...This had been recalcitrant to extensive treatment, including topical salicylic acid, 5-fluorouracil, cantharidin and numerous courses of cryotherapy and paring over the previous 6 years...Renal transplant patients represent a unique cohort in relation to verruca vulgaris, whereby impaired cell-mediated immunity can increase their susceptibility to HPV, thereby reducing effective treatment options and meaning definitive clearance may never be achieved. Our case highlights that incisional punch biopsy may represent an accessible and cost-effective approach to the treatment of verruca vulgaris in immunosuppressed patients, where alternative treatment options would necessitate numerous hospital visits."

On the possibility of using the Ti@Si superatom as a novel drug delivery carrier for different drugs: A DFT study. (PubMed, J Mol Graph Model) - "The potential application of an experimentally synthesized superatom Ti@Si as a novel drug carrier for cisplatin (DDP), isoniazid (INH), acetylsalicylic acid (ASA), 5-fluorouracil (5-Fu), and favipiravir (FPV) has been explored by density functional theory. More importantly, the release of DDP drug from the Ti@Si surface can be effectively controlled by exerting small orientation external electric fields on the DDP@[Ti@Si] complex. Therefore, this study demonstrates that Ti@Si can serve as a promising drug carrier for DDP, and thus will further expand its practical applications in the biomedical field."

Challenges of Network Meta-Analysis for Safety Outcomes: The Analysis of Tirbanibulin Against Common Treatments in Europe for Actinic Keratosis (ISPOR-EU 2022) - "OBJECTIVES: We conducted a systematic literature review and network meta-analysis (NMA) to assess the safety of a new drug, tirbanibulin 1% ointment, compared with common treatments for actinic keratosis (AK) in Europe...While eligible interventions generally reported low rates of ≤2%, including tirbanibulin with 0% and placebo between 0 and 0.6%, two of the interventions, fluorouracil 0.5%+salicylic acid and diclofenac sodium 3%, reported rates between 6 and 9%... Although severe LSRs and resulting discontinuations were key outcomes of interest, a lack of reporting and methodological challenges hindered any in-depth comparison of these safety data. FA is a useful tool to identify issues with data quality, which informs whether to compare data quantitively or only summarize qualitatively."

5-Fluorouracil 0.5%/Salicylic Acid 10% Solution in the Treatment of Ano-Genital Warts. (PubMed, Dermatol Ther) - "The clearance rate that we found for 5-FU/SAsol after 3 months of treatment is comparable with that of the other commonly used therapeutic modalities (liquid nitrogen cryotherapy, imiquimod 5% cream). In conclusion, although nowadays in Italy 5-FU/SAsol is marketed only for the treatment of actinic keratosis, our study described its effectiveness and tolerability also in the treatment of AGWs. Our data suggest that 5-FU/SAsol should be considered not only in case of resistant/recurrent AGWs but also as the first therapeutic option, especially when the number of lesions is small."

Onvansertib Triplet Shows Promise in KRAS-Mutant Metastatic Colorectal Cancer (Targeted Oncology) - "The preliminary results from the study are interesting because this is a phase Ib dose-escalation trial looking at the standard chemotherapy regimen FOLFIRI plus bevacizumab in combination with onvansertib. What we noticed is that when we looked at some of the correlative work, including capturing circulating tumor DNA (ctDNA), which demonstrated a decrease in percentage ofKRAS-mutated circulating tumor DNA. These were the patients that were treated with the investigational agents in combination with chemotherapy and bevacizumab. Not only did we see evidence of radiographic response, but we also saw evidence of a decrease in theirKRAS-mutated ctDNA."
