Black lymph node in tattoo: an easy pitfall

Tattoo is one of the most popular body arts in the world. It may be considered as a sign of belonging to a particular community as well as an expression of masculinity. However, it may also have a mere aesthetic purpose. In the past, whereas tattooing was common for male military personnel, bourgeois society spurned it. Nowadays, it is estimated that more than 24% of American adults have at least a tattoo.1 It is trending so tattooing is increasing social acceptability. The practice is equally common in men and women. In Italy, this phenomenon is less extensive than in America. However, it is definitely on the rise if we compare it with the past. Tattooing is becoming extremely popular with adolescent

The impact of biologic therapy for moderate-to-severe psoriasis on the immune responses to SARS-CoV2 infection and vaccination

Dear Editor, we explored the impact of biologics and conventional therapies for psoriasis on humoral and T-cellular responses to SARS-CoV-2 infection and vaccine. The study (EUDRA 2020-004965-37 Humanitas ICH Ethic Committee) was conducted at the Istituto Clinico Humanitas-Rozzano, Milan, and at the University of Verona, Italy. The enrolled patients were affected by moderate-to-severe psoriasis and were divided into two groups: those who had developed COVID-19 infection (group 1, n=95) and those who underwent COVID-19 vaccination (group 2, n=77

Real-life effectiveness of tildrakizumab in chronic plaque psoriasis: A 52-week multicentre retrospective study—IL PSO (Italian landscape psoriasis)

Background: Tildrakizumab is a humanized monoclonal antibody that binds selectively the p19 subunit of interleukin-23. It is approved for treatment of moderate– severe chronic plaque psoriasis. Objectives: We conducted a 52-week retrospective study to assess the effectiveness and safety of tildrakizumab in a real-life setting. Methods: Our retrospective study included 237 consecutive adults with moderateto-severe plaque psoriasis, enrolled in 10 different Italian centres, treated with tildrakizumab up to Week 52. Patient characteristics, comorbidities, previous treatmentsand the PASI (Psoriasis Area and Severity Index) score at each visit (baseline, Week 16, Week 28 and Week 52) were retrieved from the electronic medical records. The percentages of patients achieving 75%, 90% and 100% (PASI 75, PASI 90 and PASI 100) improvement in PASI with respect to baseline PASI were registered. Results: At Week 52, 90.91%, 73.55% and 58.68% of patients achieved a PASI reduction ≥75% (PASI 75), PASI 90 and PASI 100, respectively. An absolute PASI≤2 was reached by 85.95% at Week 52. Compared with Phase 3 clinical trials, we observed similar rates of PASI 75/90 responses and higher percentages of patients achieving PASI 100. Patients who had not responded to previous biologic treatments and patients with cardio-metabolic comorbidities were significantly more likely to achieve PASI 100 at Week 28 and PASI 90 at Week 52. The higher body mass index did not interfere with the odds of reaching PASI 75/90/100 at each time point. No significant safety findings were recorded throughout the study, and none of the patients had to interrupt the treatment because of adverse events. Conclusion: Our data suggest that the efficacy of tildrakizumab for plaque psoriasis in ‘real-life’ clinical practice is comparable with Phase 3 clinical trials with higher percentages of patients achieving complete skin clearance (PASI 100) at Weeks 16, 28 and 52

Effectiveness, Tolerability, and Drug Survival of Risankizumab in a Real-World Setting: A Three-Year Retrospective Multicenter Study—IL PSO (ITALIAN LANDSCAPE PSORIASIS)

Background: Risankizumab is a humanized monoclonal antibody that selectively inhibits interleukin-23. It has been approved for moderate-to-severe plaque psoriasis and has shown efficacy and safety in clinical trials and real-world experiences. This study aimed to evaluate the long-term effectiveness, safety, and drug survival of risankizumab in a real-life setting. Materials and Methods: We included patients treated with risankizumab from January 2019 to February 2023. A Psoriasis Area and Severity Index score (PASI) was collected at weeks 0, 16, 28, 52, 104, and 156, when available. The occurrence of any adverse events was recorded at each visit. Results: We enrolled 1047 patients. At week 52, a ≥90% improvement in PASI was observed in 81.44% of patients, with a continuous improvement throughout the study (88.99% and 99.07% at weeks 104 and 156, respectively). After three years of treatment, all patients involving the scalp, palms/soles, and genitalia and 95% of patients with nail psoriasis achieved a complete or almost complete skin clearance. No significant safety findings were observed, and 90.73% of the patients were still on treatment after 36 months. Conclusions: This study supports the long-term effectiveness and safety of risankizumab in a real- world setting, even in patients involving difficult-to-treat areas

Brodalumab for the treatment of plaque psoriasis in a real-life setting: a 3 years multicenter retrospective study—IL PSO (Italian landscape psoriasis)

Introduction: Brodalumab is a monoclonal antibody that targets the subunit A of the interleukin-17A receptor (IL17RA), inhibiting the signaling of various isoforms of the IL-17 family. It has been approved for the treatment of moderate-to-severe plaque psoriasis after being evaluated in three Phase-3 trials. However, long-term data on brodalumab in a real-life setting are still limited

TP63 and TP73 in cancer, an unresolved “family” puzzle of complexity, redundancy and hierarchy

AbstractTP53 belongs to a small gene family that includes, in mammals, two additional paralogs, TP63 and TP73. The p63 and p73 proteins are structurally and functionally similar to p53 and their activity as transcription factors is regulated by a wide repertoire of shared and unique post-translational modifications and interactions with regulatory cofactors. p63 and p73 have important functions in embryonic development and differentiation but are also involved in tumor suppression. The biology of p63 and p73 is complex since both TP63 and TP73 genes are transcribed into a variety of different isoforms that give rise to proteins with antagonistic properties, the TA-isoforms that act as tumor-suppressors and DN-isoforms that behave as proto-oncogenes. The p53 family as a whole behaves as a signaling “network” that integrates developmental, metabolic and stress signals to control cell metabolism, differentiation, longevity, proliferation and death. Despite the progress of our knowledge, the unresolved puzzle of complexity, redundancy and hierarchy in the p53 family continues to represent a formidable challenge

Cutaneous hypersensitivity to gluten

We enrolled 14 female patients (aged 12-60 years) affected by celiac disease (confirmed by duodenal biopsy), presenting dermatologic eczematous lesions involving their face, neck, and overall arms, after application of gluten-containing emollient cream, c bath, or face powder, or after contact with foods containing wheat and durum wheat. Five patients resulted positive to patch-by-patch with wheat and durum wheat (mild to moderate positivity) with erythema and vesicles, in correspondence of their sites of application. Utilizing gluten-free cream and bath, and wearing gloves before hand contact with food-containing wheat, in their common life, these patients showed an improvement of their cutaneous lesions and no relapses of dermatitis for a 6-month follow-up period. © 2012 American Contact Dermatitis Society.
