Impact of the environment on the health: From theory to practice.

The Erice 56 Charter titled "Impact of the environment on the health: from theory to practice" was unanimously approved at the end of the 56th course of the "International School of Epidemiology and Preventive Medicine G. D'Alessandro" held from 3rd to November 7, 2019 in Erice - Sicily (Italy) and promoted by the Study Group of "Environment and Health" of the Italian Society of Hygiene, Preventive Medicine and Public Health. The course, that included lectures, open discussions and guided working groups, was aimed to provide a general training on epidemiological and toxicological aspects of the environmental health impact, to be used by public health professionals for risk assessment, without forgetting the risk communications. At the end of the course 12 key points were agreed among teachers and students: they underlined the need of specific training and research, in the perspective of "One Health" and "Global Health", also facing emerging scientific and methodological issues and focusing on communication towards stakeholders. This Discussion highlight the need to improve knowledge of Health and Environment topic in all sectors of health and environmental prevention and management.

Dermatologists and SARS-CoV-2: the impact of the pandemic on daily practice.

Since the first case of 'pneumonia of unknown aetiology' was diagnosed at the Wuhan Jinyintan Hospital in China on 30 December 2019, what was recognized thereafter as 'severe acute respiratory syndrome coronavirus 2' (SARS-CoV-2) has spread over the four continents, causing the respiratory manifestations of coronavirus disease-19 (COVID-19) and satisfying the epidemiological criteria for a label of 'pandemic'. The ongoing SARS-CoV-2 pandemic is having a huge impact on dermatological practice including the marked reduction of face-to-face consultations in favour of teledermatology, the uncertainties concerning the outcome of COVID-19 infection in patients with common inflammatory disorders such as psoriasis or atopic dermatitis receiving immunosuppressive/immunomodulating systemic therapies; the direct involvement of dermatologists in COVID-19 care for patient assistance and new research needs to be addressed. It is not known yet if skin lesions and derangement of the skin barrier could make it easier for SARS-CoV-2 to transmit via indirect contact; it remains to be defined if specific mucosal or skin lesions are associated with SARS-CoV-2 infection, although some unpublished observations indicate the occurrence of a transient varicelliform exanthema during the early phase of the infection. SARS-CoV-2 is a new pathogen for humans that is highly contagious, can spread quickly, and is capable of causing enormous health, economic and societal impacts in any setting. The consequences may continue long after the pandemic resolves, and new management modalities for dermatology may originate from the COVID-19 disaster. Learning from experience may help to cope with future major societal changes.

Certolizumab for the treatment of psoriasis and psoriatic arthritis: a real-world multicentre Italian study.

BACKGROUND: Certolizumab, a pegylated tumour necrosis factor-α inhibitor, reduced disease activity in randomized trials of patients with psoriasis and psoriatic arthritis. Real-life data are missing. OBJECTIVE: To confirm the effectiveness and safety of certolizumab in patients with psoriasis and psoriatic arthritis in routine clinical practice. METHODS: In this retrospective study involving 11 Italian sites, patients with psoriasis and psoriatic arthritis received subcutaneous certolizumab (400 mg loading dose at 0, 2 and 4 weeks, followed by 200 mg every 2 weeks) for up to 52 weeks. Primary outcomes included mean change from baseline in Psoriasis Area and Severity Index (PASI) and modified Nail Psoriasis Severity Index (mNAPSI) scores, and the proportion of patients achieving a 75%, 90% or 100% reduction in PASI score. Other endpoints included Disease Activity Score computed on 44 joints correlated with the erythrocyte sedimentation rate during the first hour (DAS44-ESR), Tender Joint Count (TJC), Swollen Joint Count (SJC), pain [visual analogue scale (VAS) score], inflammatory markers and quality of life (QOL). RESULTS: In the study were enrolled 153 patients (mean age: 55 years). Certolizumab reduced the mean PASI score from baseline by 4.45, 6.30 and 7.58 at weeks 12, 24 and 52, respectively (P < 0.001 for all). At weeks 24 and 52, 69.6% and 83.3% of patients had a PASI score ≤3. DAS44-ESR, TJC, SJC and mNAPSI scores, and pain VAS were also all significantly improved from baseline at each time point. C-reactive protein levels decreased during treatment, being significant at week 24. On multivariate analysis, psoriasis duration, baseline PASI, mNAPSI and pain VAS scores were found to be predictive of the improvement in PASI score at week 12. CONCLUSION: Certolizumab displayed also in the real-life encouraging results in both psoriasis and psoriatic arthritis patients.

Robotic stereotactic ablative radiotherapy for renal cell carcinoma in patients with impaired renal function.

BACKGROUND: Robotic stereotactic ablative radiotherapy (SABR) is currently under investigation as a noninvasive treatment option for patients with renal cell carcinoma (RCC). For radiation therapy of RCC, tumor motion and the need for high ablative doses while preserving the remaining renal parenchyma is a challenge. We aimed to analyze the safety and efficacy of robotic radiosurgery in RCC in a specific difficult subgroup of patients with impaired renal function. METHODS: We retrospectively identified all patients with RCC, treated with robotic SABR and motion compensation in our institution between 2012 and 2017. Either single fraction SABR of 24 or 25 Gy or 3 fractions of 12 Gy prescribed to the 70% isodose line was applied. Local control, overall survival, radiation side effects were evaluated together with renal function and tumor motion. RESULTS: We analyzed data of 13 lesions treated in 10 patients with clear cell RCC and a mean age of 70.5 ± 13.6 years (range: 48-87). Prior to SABR, 8 patients underwent previous complete and/or partial nephrectomy, 7 patients presented with chronic kidney disease ≥ stage 3. The median of minimum, mean and maximum planning target volume doses were 23.2, 29.5 and 35.0 Gy for single fraction and 24.4, 42.5 and 51.4 Gy for the three fractions regime. Persistent local control by robotic SABR was achieved in 9 out of 10 patients (92.3% of all lesions) within a median follow-up period of 27 month (range: 15-54). One patient underwent nephrectomy due to progressive disease and sufficient renal function of the contralateral kidney. Renal function remained stable with a mean estimated glomerular filtration rate (eGFR) of 51.3 ± 19.7 ml/min at baseline and 51.6 ± 25.8 ml/min at follow-up. The largest respiratory-induced tumor motion was seen in superior-inferior direction, compensated by the CyberKnife with mean targeting errors of maximal 2.2 mm. CONCLUSIONS: Robotic SABR is technically feasible for the treatment of RCC in preexisting kidney disease with good local tumor control at about 2 years follow-up. Robotic SABR with motion tracking offers a valid treatment option for patients, who are at increased risk for progression to end-stage renal disease due to partial nephrectomy or ablative techniques.

Consensus on the management of patients with psoriatic arthritis in a dermatology setting.

BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with psoriasis (PsO). Early diagnosis and prompt therapeutic intervention are crucial for limiting PsA progression and prevention of disability. Dermatologists are in a privileged position to detect early PsA. The management of patients with PsA in the dermatology setting is widely variable. OBJECTIVE: To provide practical recommendations for the management of patients with PsA in the dermatology setting including early diagnosis and treatment. METHODS: A consensus document was written by an expert panel composed by dermatologists (n = 12) and rheumatologists (n = 6). Eleven highly relevant questions were selected and elaborated with answers/statements based on a narrative literature review. The resulting document was discussed in a face-to-face meeting adopting a nominal group technique to reach consensus (i.e. 100% agreement) using the Delphi method. RESULTS: A consensus was achieved in defining the following: the clinical characteristics differentiating inflammatory and non-inflammatory signs and symptoms of joint disease; the most important differential diagnoses of PsA in clinical practice; the most useful screening questionnaires, serum laboratory tests and imaging techniques for the detection of early PsA; the criteria for dermatologist to refer patients with PsO to rheumatologist; the criteria for the diagnosis of PsA; the selection of the indices that the dermatologist could use for measuring the activity and severity of PsA in clinical practice; when systemic steroids and/or intra-articular steroid injections are indicated in the treatment of PsA. Finally, systemic treatments including synthetic and biologic disease-modifying antirheumatic drugs to be considered for the treatment of PsA have been reported. CONCLUSIONS: The implementations of these practical recommendations could be very helpful for the management of patients with PsA in the dermatology setting including early diagnosis and treatment.

Multicenter prospective crossover study on new prosthetic opportunities in post-laryngectomy voice rehabilitation.

The aim of this study was to assess the clinical experience of three Italian centers using the third generation Provox Vega prosthesis, in terms of device life and voice outcome, comparing the results with the second generation Provox 2 prosthesis in the same sample. A prospective multicenter crossover study was performed in three phases. In the first phase we performed a reassessment, for enrollment purposes, of patients who were categorized into four different groups [normal ­ group A; radio-treated ­ group B; gastroesophageal reflux disease (GERD) ­ group C; and elderly subjects ­ group D]. In the second and third phases, all patients were monitored for prosthetic device life and assessed for objective and subjective voice characteristics after introducing Provox 2 and Provox Vega prostheses. In patients with Provox 2 prosthesis, the mean life was 165 days in group A, 148 days in group B, 91 days in group C and 188 days in group D. In Provox Vega patients, mean in situ prosthesis life was 213 days in group A, 182 days in group B, 118 days in group C and 227 days in group D. The perceptual voice data showed a better rating across all parameters for the Provox Vega samples compared to those of Provox 2. In this paper, we report the first multicenter crossover study comparing different prosthetic models in the same patients, categorized in relation to different typologies of tracheoesophageal rehabilitative status. Result analyses confirmed an optimal stability of the Provox Vega compared to the Provox 2, in terms of device life and perceptual voice parameters.

Adalimumab is a safe option for psoriasis patients with concomitant hepatitis B or C infection: a multicentre cohort study of 37 patients and review of the literature.

BACKGROUND: Little data are available about the safety of TNF-α inhibitors in patients with HCV and HBV infection. In particular, data concerning the use of adalimumab in patients with psoriasis and concomitant viral hepatitis are lacking and little is known about the drug's real safety in this context. OBJECTIVE: To assess the long-term safety of adalimumab in a group of 17 consecutive psoriatic patients affected by chronic HBV infection and 20 consecutive psoriatic patients affected by chronic HCV infection. METHODS: Thirty-seven consecutive patients with psoriasis and concomitant HBV or HCV infection being treated with adalimumab at four Italian referral centres (Modena, Padova, Verona and Turin) were assessed before the treatment and at the end of follow-up. Viral load and radiological studies (echography, Fibroscan) were also carried out in some of the patients. RESULTS: The patients responded well to treatment and did not show any HBV or HCV reactivation in a mean follow-up period of 27 and 40 months, respectively. The fibrosis score in eight HCV patients showed a slight reduction: pretreatment mean value 5.83 and post-treatment mean value 5.65. CONCLUSION: The use of adalimumab seems to be safe in patients with severe psoriasis and HBV or HCV infection. Nevertheless, large-scale prospective studies will be able to provide vital information on the impact of anti-TNF treatment on hepatic function in patients with psoriasis and concomitant chronic HCV or HBV infection and appropriate monitoring scheduling.

Dose adjustment of biologic therapies for psoriasis in dermatological practice: a retrospective study.

INTRODUCTION: Despite the large routine use of biologic drugs in psoriasis treatment, the majority of studies do not take into consideration dose-adjustment practice in 'real-life' dermatological setting. In routine clinical practice, the disease management may include a large number of conditions requiring non-standard dosage regimens, including dose escalation, dose reduction and/or off-label treatment interruption. OBJECTIVE: The ONDA (Outcome of non-standard dosing regimen in Psoriasis and Psoriatic Arthritis) study aim was to retrospectively analyse dose-adjustment strategies among biologic therapies for psoriasis in dermatological practice during a 3-year period. RESULTS: This retrospective, observational, multicentre study was carried out in 350 patients (68% male, 32% female) affected by plaque-type psoriasis (Pso) with a coexistence of psoriatic arthritis in 164 patients (46.9%). At baseline mean PASI score was 14.9 (SD 7.2). Dose adjustment was demonstrated to be a common practice with 70/350 patients (20%) who needed a dose variation during the treatment time, in particular a dose increase in 20/70 patients (28.6%) and a dose reduction in 50/70 patients (71.4%). Dose increase was due to inefficacy on Pso parameters in 60% of cases and to inefficacy of PsA parameters in 40% of cases, while dose reduction (or temporary off-label treatment interruption) was due to prolonged remission in 54% of cases, other reason in 18% of cases, patient choice or request in 14% of cases, occurrence of concomitant event in 12% of cases. CONCLUSION: Dose adjustment is a common clinical practice, consisting of frequent dose reduction when a disease prolonged remission is obtained or dose increase to improve efficacy on Pso and PsA disease parameters.

Italian guidelines on the systemic treatments of moderate-to-severe plaque psoriasis.

Psoriasis is a common disease, which has a considerable impact on the healthcare system. Therefore, appropriate use of therapeutic resources is very important. Management of psoriasis in daily clinical practice is highly variable because many issues are still debated and not definitely addressed by the evidence-based medicine. Moreover, the different availability and reimbursability of drugs in each country justifies national guidelines. Expert consensus can provide helpful guidelines for optimizing patient care. A total of 20 dermatologists from different areas of Italy and with large experience in the treatment of psoriasis agreed to participate in the guidelines expert panel who aimed to reach consensus on the factors influencing psoriasis severity, the indications for systemic treatments, the parameters to be considered in the choice of treatment, and the factors to be considered in the choice of biological treatment. The recommendations for the use, screening and monitoring of systemic therapies were based on the 2015 S3 European Dermatology Forum/European Academy of Dermatology and Venereology psoriasis guidelines. Recommendations on the treatment of psoriasis in special patient populations were also agreed. The final document was discussed in a meeting moderated by a facilitator with participation of the entire group and adopting a nominal group technique to reach consensus. A statement was regarded as consented when agreement was achieved by at least 75% of the voting experts according to the Delphi procedure.

Humidifiers for oxygen therapy: what risk for reusable and disposable devices?

INTRODUCTION: Nosocomial pneumonia accounts for the vast majority of healthcare-associated infections (HAI). Although numerous medical devices have been discussed as potential vehicles for microorganisms, very little is known about the role played by oxygen humidifiers as potential sources of nosocomial pathogens. The purpose of this research was to evaluate the safety of the reuse of humidifiers by analysing the rate of microbial contamination in reusable and disposable oxygen humidifiers used during therapy, and then discuss their potential role in the transmission of respiratory pathogens. METHODS: Water samples from reusable and disposable oxygen humidifiers were collected from different wards of the University Hospital of Messina, Italy, where nosocomial pneumonia has a higher incidence rate due to the "critical" clinical conditions of inpatients. In particular, we monitored the Internal Medicine and Pulmonology wards for the medical area; the General Surgery and Thoracic and Cardiovascular Surgery wards for the surgical area and the Intensive Care Unit and Neonatal Intensive Care Unit for the emergency area. The samples were always collected after a period of 5 days from initial use for both types of humidifiers. Samples were processed using standard bacteriological techniques and microbial colonies were identified using manual and automated methods. RESULTS: High rates of microbial contamination were observed in samples from reusable oxygen humidifiers employed in medical (83%), surgical (77%) and emergency (50%) areas. The most relevant pathogens were Pseudomonas aeruginosa, amongst the Gram-negative bacteria, and Staphylococcus aureus, amongst the Gram-positive bacteria. Other pathogens were detected in lower percentage. The disposable oxygen humidifier samples showed no contamination. CONCLUSIONS: This research presents evidence of the high rate and type of microbial contamination of reusable humidifiers employed for oxygen therapy. These devices may thus be involved in the transmission of potential pathogens. It could be important, for the prevention of nosocomial pneumonia, to replace them with singleuse humidifiers for which the absence of microbial contamination has been confirmed.

Assessment of Interexaminer Agreement in the Detection of Condyle Morphology and positioning with Two Methods: Radiographic and Tomographic.

AIM: This study aims at evaluating the interexaminer agreement between radiographic and tomographic methods to determine condyle morphological variations and positioning. MATERIALS AND METHODS: The sample comprised 100 individuals aged 13 to 30 years, from the patient files of University of North Paraná. The assessment of condyles morphology and positioning was performed in images of digital panoramic radiography (DPR) and reconstructed panoramic images from the cone beam computed tomography (CBCT) scans, by using the Dolphin three-dimensional (3D) program. The condyle morphology was categorized as flat, convex, and angular as well as its positioning classified into anterior, posterior, and concentric. Three calibrated examiners performed this subjective evaluation. After that, another examiner performed an objective assessment of the condyles positioning using tomographic sagittal scans of the condyles, applying the same 3D program. This objective evaluation of the condyle position, considered the gold standard (GS), was achieved by using a formula based on the measurement values of the joint spaces, anterior and posterior. The kappa test was used to assess the interexaminer agreement in determining the condyles morphology and positioning, as well as between the condyle positioning results determined by the examiners and the GS. RESULTS: The results showed poor agreement among examiners and between the subjective and objective condyle positioning evaluation. CONCLUSION: It was concluded that the panoramic radiography (PR), either digitalized or reconstructed from CBCT scans, is not suitable for determining variations in condyle morphology and position. CLINICAL SIGNIFICANCE: Whenever it is necessary to evaluate the mandibular condyle during the orthodontic screening, the orthodontist should consider another image modality better than the PR.

PSOCUBE, a multidimensional assessment of psoriasis patients as a both clinically/practically sustainable and evidence-based algorithm.

BACKGROUND: There is increasing awareness of the clinical relevance of psoriasis comorbidities and of the importance of timely and effective screening for such comorbidities in the management of psoriatic patients. Previous works have focused on assessing evidence for prevalence of comorbidities and on the best available evidence for sensitivity in diagnosing suspected comorbidities. No algorithms are available, which have been tested on large numbers of physicians concerning the acceptance of such algorithms both by practicing clinical dermatologists and by their consulting specialists from other fields. OBJECTIVE: To propose a multidimensional assessment algorithm for psoriasis comorbidities which may prove at the same time enough sensitive and practically sustainable in daily clinical practice. METHODS: After an exhaustive literature search, we performed a Delphi procedure involving 50 dedicated dermatological centres to obtain a standardized assessment algorithm, which would meet requirements of sustainability and acceptability both from the point of view of Evidence-Based Medicine as well as from the point of view of practical and clinical feasibility: to meet both requirements, results from the Delphi procedure were elaborated and modified by a restricted panel of experts. RESULTS: The procedure has yielded PSOCUBE, a three-dimensional table comprising 14 clinical examination and history taking items, 32 screening laboratory and instrumental exams and 11 clinimetric scores. CONCLUSION: PSOCUBE, a simple algorithm, may be employed by practising dermatologists to perform standardized assessment procedures on psoriatic patients raising the chances of early recognition of patients at risk for comorbidities, thus fostering more effective prevention; PSOCUBE may therefore contribute to reduce the overall impact of this chronic, widespread disease.

Reflectance confocal microscopy for plaque psoriasis therapeutic follow-up during an anti-TNF-α monoclonal antibody: an observational multicenter study.

BACKGROUND: Psoriasis is a chronic recurrent inflammatory skin disease that affects 2-3% of the world population. Biologics are relatively new systemic treatments that block molecular steps important in the pathogenesis of psoriasis. In vivo Reflectance confocal microscopy (RCM) is a non-invasive, imaging technique already reported to be useful in the evaluation of the follow-up of PP under treatment with topical actives and phototherapy. No reports on systemic treatments have been proposed in literature so far. OBJECTIVE: The aim of this study was to evaluate the feasibility of RCM in the monitoring of microscopic response to a subcutaneous anti-TNF treatment, Adalimumab. METHODS: One target lesion with typical clinical aspect, from 48 psoriatic patients, was evaluated using RCM at baseline, after 4 and 8 weeks of treatment. RESULTS: Microscopic confocal changes were followed up during treatment. Results disclosed identification of early microscopic evidence of the anti-inflammatory activity of Adalimumab not detected at clinical examination. Confocal feature related to the effect of TNF-α on melanocytes activity has been also identified. CONCLUSION: Early detected RCM parameters related to Adalimumab activity could be used to identify an early response to the treatment. RCM seems to be able to give useful and practical information about follow-up in patients with PP under treatment with Adalimumab.
