Ultrasound-guided injection of intralesional steroids in acute hidradenitis suppurativa lesions: A prospective study.

The management of hidradenitis suppurativa (HS) flares with intralesional steroids lacks strong scientific evidence but limited data suggest that it may be useful. The objective of this study is to assess the clinical and ultrasound responses of HS flares to ultrasound-guided injections of intralesional triamcinolone (40 mg/ml) with a dilution 1:4 versus 1:2 at 30-day (t1), 60-day (t2), and 90-day (t3) follow-up. We recruited patients with ≤3 acute lesions, unresponsive to topical therapy. At baseline we assessed lesions clinically and by ultra-high frequency ultrasound (48 or 70 MHz) and randomly performed an ultrasound-guided injection of triamcinolone. Assessments were repeated at t1, t2, and t3 follow-up, re-injecting the lesion in the case of no or partial response. We treated 49 lesions: 38.8% showed improvements at t1; 46.9% at t2; 6% at t3; and 8.3% showed no clinical and ultrasound improvements. Long-term follow-up data confirmed a statistically significant reduction in Visual Analogue Scale (VAS)-pain, Dermatology Life Quality Index (DLQI), and HS-Physician Global Assessment (HS-PGA), as well as edema and vascular signals. No adverse effects were reported. Our study suggests that ultrasound-injections with a 1:2 dilution are beneficial for HS flares that do not respond to topical treatment and should be included in the therapeutic algorithm.

AtopyReg®, the Prospective Italian Patient Registry for Moderate-to-Severe Atopic Dermatitis in Adults: Baseline Demographics, Disease Characteristics, Comorbidities, and Treatment History.

BACKGROUND AND OBJECTIVE: AtopyReg® is a multicenter, prospective, observational, non-profit cohort study on moderate-to-severe atopic dermatitis in adults promoted in 2018 by the Italian Society of Dermatology and Venereology (SIDeMaST). We aimed to describe baseline demographics, disease characteristics, comorbidities, and therapeutic data of adult patients affected by moderate-to-severe atopic dermatitis. METHODS: Patients were selected based on the following inclusion criteria: age ≥ 18 years; Eczema Area and Severity Index score ≥ 16 or localization in visible or sensitive areas (face, neck, hands, or genitalia), or a Numeric Rating Scale itch score ≥ 7 or a Numeric Rating Scale sleep loss score ≥ 7, or a Dermatology Life Quality Index score ≥ 10. Demographic and clinical data at baseline were recorded and analyzed. RESULTS: A total of 1170 patients (male 51.1%; mean age: 44.7 years; range 18-90 years) were enrolled by 12 Italian Dermatology Units between January 2019 and November 2022. Skin lesions were eczematous in 83.2% of patients, the most involved site were the flexures (53.9%), face (50.9%), and neck (48.0%). Mean Eczema Area and Severity Index score was 22.3, mean Dermatology Life Quality Index value was 17.6, mean Patient Oriented Eczema Measure score was 13.1, and mean Numeric Rating Scale itch and sleep loss scores were 7.6 and 5.9, respectively. Previous systemic therapies were corticosteroids in 77.7% of patients, antihistamines in 50.3% of patients, and cyclosporine A in 42.6% of patients. CONCLUSIONS: This baseline data analysis deriving from AtopyReg® provides real-life evidence on patients with moderate-to-severe atopic dermatitis in Italy confirming the high burden of atopic dermatitis with a significant impact on patients' quality of life.

Elacestrant (oral selective estrogen receptor degrader) Versus Standard Endocrine Therapy for Estrogen Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Advanced Breast Cancer: Results From the Randomized Phase III EMERALD Trial.

PURPOSE: Patients with pretreated estrogen receptor (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer have poor prognosis. Elacestrant is a novel, oral selective ER degrader that demonstrated activity in early studies. METHODS: This randomized, open-label, phase III trial enrolled patients with ER-positive/HER2-negative advanced breast cancer who had one-two lines of endocrine therapy, required pretreatment with a cyclin-dependent kinase 4/6 inhibitor, and ≤ 1 chemotherapy. Patients were randomly assigned to elacestrant 400 mg orally once daily or standard-of-care (SOC) endocrine monotherapy. Primary end points were progression-free survival (PFS) by blinded independent central review in all patients and patients with detectable ESR1 mutations. RESULTS: Patients were randomly assigned to elacestrant (n = 239) or SOC (n = 238). ESR1 mutation was detected in 47.8% of patients, and 43.4% received two prior endocrine therapies. PFS was prolonged in all patients (hazard ratio = 0.70; 95% CI, 0.55 to 0.88; P = .002) and patients with ESR1 mutation (hazard ratio = 0.55; 95% CI, 0.39 to 0.77; P = .0005). Treatment-related grade 3/4 adverse events occurred in 7.2% receiving elacestrant and 3.1% receiving SOC. Treatment-related adverse events leading to treatment discontinuations were 3.4% in the elacestrant arm versus 0.9% in SOC. Nausea of any grade occurred in 35.0% receiving elacestrant and 18.8% receiving SOC (grade 3/4, 2.5% and 0.9%, respectively). CONCLUSION: Elacestrant is the first oral selective ER degrader demonstrating a significant PFS improvement versus SOC both in the overall population and in patients with ESR1 mutations with manageable safety in a phase III trial for patients with ER-positive/HER2-negative advanced breast cancer.

Kernel machine approach to testing the significance of multiple genetic markers for risk prediction.

There is growing evidence that genomic and proteomic research holds great potential for changing irrevocably the practice of medicine. The ability to identify important genomic and biological markers for risk assessment can have a great impact in public health from disease prevention, to detection, to treatment selection. However, the potentially large number of markers and the complexity in the relationship between the markers and the outcome of interest impose a grand challenge in developing accurate risk prediction models. The standard approach to identifying important markers often assesses the marginal effects of individual markers on a phenotype of interest. When multiple markers relate to the phenotype simultaneously via a complex structure, such a type of marginal analysis may not be effective. To overcome such difficulties, we employ a kernel machine Cox regression framework and propose an efficient score test to assess the overall effect of a set of markers, such as genes within a pathway or a network, on survival outcomes. The proposed test has the advantage of capturing the potentially nonlinear effects without explicitly specifying a particular nonlinear functional form. To approximate the null distribution of the score statistic, we propose a simple resampling procedure that can be easily implemented in practice. Numerical studies suggest that the test performs well with respect to both empirical size and power even when the number of variables in a gene set is not small compared to the sample size.

Definition of treatment goals in terms of clinician-reported disease severity and patient-reported outcomes in moderate-to-severe adult atopic dermatitis: a systematic review.

BACKGROUND: Atopic dermatitis (AD) is a chronically relapsing skin disease. Although a definitive cure is not available, appropriate treatment can control the disease. The advent of biologic drugs has led to the need for a clear definition of the disease severity and treatment response. A standardized list of outcomes that defines clinician-reported disease severity and patients' reported severity are therefore essential. Solid criteria to define the response to treatment and treatment failure are lacking to date. OBJECTIVE: This systematic review defines treatment goals in terms of clinician-reported disease severity and patient-reported outcomes, referring to the published moderate-to-severe AD clinical trials. The application of these goals in daily clinical practice will ensure a better selection of available treatment options, thus increasing patient quality of care. MATERIALS AND METHODS: A systematic literature search was performed to identify the treatments goals of randomized controlled clinical trials (RCTs) on moderate-to-severe adult AD published between January 2000 and October 2020. RESULTS: In total, 14 studies met the eligibility criteria. The most widely used tools in terms of clinician-reported disease severity were the Scoring of Atopic Dermatitis (SCORAD) followed by the Eczema Area Severity Score (EASI) and Investigator Global Assessment (IGA). For disease severity scales as efficacy outcome in RCTs, the greatest standardization and reproducibility was for improvement of at least 50% in EASI score and IGA score reduction of ≥2 grades from baseline. The most widely used tools from the patients' perspective were the Dermatology Life Quality Index (DLQI), Numeric Rate Scale (NRS)-itch and Patient Oriented Eczema Measure Score (POEM). In terms of patients' reported efficacy outcomes in RCTs, a numerical DLQI, NRS-itch and POEM score improvement of at least 4 points from baseline was reported. CONCLUSIONS: This systematic review highlights the need for collaboration between experts in order to define and optimize treatment outcomes. Despite considerable progress in harmonizing outcome measures, promoted by the foundation of the Harmonizing Outcome Measures for Eczema (HOME) initiative in 2008, our results demonstrate that this endpoint is still an unmet need. Based on the literature data we propose a minimum treatment goal algorithm for use in daily clinical practice aimed at stimulating a discussion on how the care of AD patients could be further improved.

Tuscan Consensus on the diagnosis, treatment and follow up of adult atopic dermatitis.

Atopic dermatitis (AD) is an inflammatory disease with a chronic-relapsing course that is intensely itchy. A correct diagnosis of AD in adults and consequently appropriate clinical therapeutic management is a critical issue for extreme clinical expression heterogeneity and various grades of disease severity. In order to ensure high levels of care and standardization of clinical therapeutic management of Adult AD, the decision was taken to create an AD Tuscan Consensus Group (the Group), to work on and validate a consensus based regional clinical-therapeutic management model. The aims of the Group were to find agreement on the criteria for diagnosis, scoring of severity, multidisciplinary approach and treatment of adult atopic dermatitis and to create an easier way for patients to access specialized dermatology outpatient services and importantly to reduce waiting lists and costs related to the management of AD. The Tuscan Consensus Group adopted a simplified Delphi method, in three principal steps: 1) literature metanalysis and critical review of patient's clinical experience to identify the main areas considered questionable or uncertain; 2) discussion of those areas requiring consensus and statement definition through four different sub-committees (diagnosis, severity evaluation, scoring and comorbidities); 3) a consensus based simplified process with final approval of each statement by plenary vote with approval >80% of the participants. The Group here presents and discusses the consensus based recommendation statements on adult atopic dermatitis.

Itch in Chronic Wounds: Pathophysiology, Impact, and Management.

Background: The aims of this review are to analyze the current literature regarding the characteristics and pathophysiological mechanisms of itch in chronic wounds, to assess the impact on quality of life and delayed-healing, to focus on the best strategies of prevention and treatment, to highlight the importance of on-going research in order to fully understand the pathophysiology, and to improve the management of target therapies. Methods: A systematic literature review was performed using MEDLINE, PubMed, Embase, Scopus, ScienceDirect, and the Cochrane Library. We included a total of 11 articles written in English with relevant information on the pathophysiology of itch in chronic wounds and on management strategies. Results: Itch in chronic wounds was found to be correlated with xerosis, larger wound areas, necrotic tissue and amount of exudate, peripheral tissue edema, sclerosis, granulation tissue, contact dermatitis, and bacterial burden, as well as with lower quality of life. Conclusions: Although there are several aspecific pharmacological and non-pharmacological approaches, there appears to be no validated prevention or management strategy for itch in chronic wounds. Further studies are needed to clarify the association and pathophysiology of itch in chronic wounds, to evaluate the safety and efficacy of topical treatments on perilesional skin to reduce itch, to characterize multidimensional sensations of itch in chronic wounds, to identify specific cytokine and chemokine expressions that are correlated to a tailored-based approach, and to develop practical guidelines.

Dermoscopic and reflectance confocal microscopy features of two cases of vulvar basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common malignant skin cancer. Its genital localization is rare, and the diagnosis in this site could be challenging. Here, we report two patients with vulvar BCC and describe their clinical, dermoscopic and in vivo and ex vivo reflectance confocal microscopic (RCM) features. Dermoscopy and RCM can be useful tools for helping the clinical diagnosis of vulvar BCC and for identifying the correct surgical margins.

Analysis of gene expression profiles reveals novel correlations with the clinical course of colorectal cancer.

In order to discover potential markers of prognosis in colorectal cancer (CRC) we have determined gene expression profiles, using cDNA microarrays in CRC samples obtained from 19 patients in Dukes stages C and D, with favorable clinical course (Dukes C patients, survival >5 years after surgery, group A, n=7) or unfavorable clinical course (Dukes stage C and D patients, survival <5 years after surgery, group B, n=12). Gene expression was measured in RNA from each tumor, using a pool of equal amounts of RNA from all tumors as a reference. To identify and rank differentially expressed genes we used three different analytical methods: (i) Significance Analysis of Microarrays (SAM), (ii) Cox's Proportional Hazard Model, and (iii) Trend Filter (a mathematical method for the assessment of numerical trends). The level of expression of a gene in an individual tumor was regarded as of interest when that gene was identified as differentially expressed by at least two of these three methods. By these stringent criteria we identified eight genes (ITGB2, MRPS11, NPR1, TXNL2, PHF10, PRSS8, KCNK3, JAK3) that were correlated with prolonged survival after surgery. Pathway analysis showed that patients with favorable prognosis had several activated metabolic pathways (carbon metabolism, transcription, amino acid and nitrogen metabolism, signaling and fibroblast growth factor receptor pathways). To further validate individual gene expression findings, the RNA level of each gene identified as a marker with microarrays was measured by real-time RT-PCR in CRC samples from an independent group of 55 patients. In this set of patients the Cox Proportional Hazard Model analysis demonstrated a significant association between increased patient survival and low expression of ITGB2 (p = 0.011) and NPR1 (p = 0.023) genes.

[Long stapled haemorrhoidectomy versus Milligan-Morgan procedure: short- and long-term results of a randomised, controlled, prospective trial]. / Emorroidectomia secondo Longo vs Milligan-Morgan: risultati a breve e lungo termine di uno studio prospettico, randomizzato, controllato. Analisi costo-beneficio.

The aim of this study was to assess the short- and long-term results of treatment for haemorrhoids by prospectively comparing two techniques, namely, stapled rectal prolapse mucosectomy according to Longo and open hemorrhoidectomy. One hundred consecutive patients were randomised to stapled (50 patients) or manual hemorrhoidectomy (50 patients). We analysed postoperative pain, preoperative and postoperative anorectal function, intraoperative and postoperative complications, time needed to return to work and to normal social activities, and costs. Long-term follow data were obtained by means of an outpatient visit. The operative time of the stapled technique was less than that of open haemorrhoidectomy (22 vs 35 minutes). Two cases of early postoperative bleeding occurred after the stapled technique. The mean pain score on a visual scale was significantly less in patients undergoing the stapled technique. In addition, the time needed to return to work and to normal social activities was significantly less after the stapled technique, which, however, proved to be a more expensive procedure. Stapled mucosectomy of the prolapsed rectal mucosa is a safe, rapid, and relatively painless technique, which has a low incidence of complications. It can be performed in a day surgery unit. Patient satisfaction, early return to normal activities and good long-term results counterbalance the high cost of the procedure.

Ranolazine in the treatment of atrial fibrillation: Results of the dose-ranging RAFFAELLO (Ranolazine in Atrial Fibrillation Following An ELectricaL CardiOversion) study.

BACKGROUND: Currently available antiarrhythmic agents for the treatment of atrial fibrillation (AF) have important limitations, leaving an unmet need for safe and effective therapy. Ranolazine is an approved antianginal agent with a favorable safety profile and electrophysiologic properties suggesting a potential role in the treatment of AF. OBJECTIVE: The purpose of this study was to assess the safety and efficacy of ranolazine in the prevention of AF recurrence after successful electrical cardioversion and to ascertain the most appropriate dose of this agent. METHODS: This prospective, multicenter, randomized, double-blind, placebo-control parallel group phase II dose-ranging trial randomized patients with persistent AF (7 days to 6 months) 2 hours after successful electrical cardioversion to placebo, or ranolazine 375 mg, 500 mg, or 750 mg bid. Patients were monitored daily by transtelephonic ECG. The primary end-point was the time to first AF recurrence. RESULTS: Of 241 patients randomized, 238 took at least 1 drug dose. Ranolazine proved to be safe and tolerable. No dose of the drug significantly prolonged time to AF recurrence. AF recurred in 56.4%, 56.9%, 41.7%, and 39.7% of patients in the placebo, ranolazine 375 mg, ranolazine 500 mg, and ranolazine 750 mg groups, respectively. The reduction in overall AF recurrence in the combined 500-mg and 750-mg groups was of borderline significance compared to the placebo group (P = .053) and significant compared to 375-mg group (P = .035). CONCLUSION: No dose of ranolazine significantly prolonged time to AF recurrence. However, the 500-mg and 750 mg-groups combined reduced AF recurrences, suggesting a possible role for this agent in the treatment of AF.

Early and late outcome after surgery for colorectal cancer: elective versus emergency surgery.

AIMS AND BACKGROUND: Emergency surgery for colorectal cancer is associated with a higher postoperative morbidity and mortality rate and a poor long-term outcome compared with elective surgery. The aim of the present study was to compare early and late outcome after elective and emergency surgery for malignant colorectal cancer, looking for the principal determinants of a worse outcome after emergency colorectal surgery. METHODS: A retrospective study of 236 patients presenting with colorectal cancer over an 8-year period was undertaken. Of these, 118 presented as emergencies, whereas 118 patients, well matched for age, sex, site of tumor and TNM admitted as elective, were included in the study. Data reviewed included postoperative mortality and morbidity and long-term outcome. RESULTS: The 30-day operative mortality rate was significantly higher in the emergency group than in the electively treated group (11.9% versus 3.4%, P < 0.01). The higher mortality rate was observed in the perforation group. The 30-day operative morbidity was higher in the emergency group (27.1% versus 12.7%, P < 0.05). Anastomotic failure was a serious complication: following primary resection, we observed 4 non-fatal (5.4%) and two fatal (2.7%) anastomotic leaks after 74 primary anastomoses. Among emergency-treated patients, the procedures characterized by the highest percentage of postoperative complications were three-stage resections (63.6%). The 5-year survival rate was greater after elective surgery (59% versus 39%). CONCLUSIONS: The early and long-term outcome following emergency colorectal surgery was significantly lower than that after elective surgery. Although medical complications in patients with end-stage cancer played an important role, surgical failures still had an important impact on outcome.

[Impact of the sentinel lymph node in the staging of colorectal carcinoma]. / Impatto del linfonodo sentinella nella stadiazione del carcinoma colorettale.

In view of the very good results obtained by lymphatic mapping and sentinel node biopsy in the staging of patients with melanoma or breast cancer, we investigated the feasibility of intraoperative regional lymphatic mapping in patients with primary colorectal carcinoma. The aim of this study was to determine whether lymphatic mapping and sentinel node assessment can identify aberrant drainage patterns or make for better staging of the neoplasm in those cases with no or only minimal lymphatic neoplastic involvement. Sixteen consecutive patients with primary colorectal cancer (stage T2-T3) but without macroscopic involvement of the lymphatic system underwent intraoperative lymphatic mapping by injecting 1-1.5 ml of isosulfan blue dye. The identified and resected sentinel nodes were examined using conventional haematoxylin-eosin staining and cytokeratin immunohistochemistry. Sentinel node identification was successful in 15 out of 16 cases (93.8%). In 11 cases (73.3%) sentinel node status correctly predicted the final staging. The false-negative rate was 26.7%. Immunohistochemical analysis revealed the presence of micrometastasis in one case (6.7%), which was consequently upstaged. In cases of colorectal cancer lymphatic mapping is an easy, perfectly feasible technique. However, in our experience, it would not appear to significantly improve the accuracy of the histopathological staging of colorectal carcinoma.
