Abstract
INTRODUCTION Nowadays, despite the wide availability of biological drugs and apremilast for psoriasis management, there is always a need for new therapies to customize the therapeutic approach on the basis of the patient's clinical features and comorbidities, especially in order to achieve a prolonged therapeutic response. Thus, new treatment strategies are required to offer patients a personalized approach. In this scenario, major knowledge on psoriasis pathogenesis led to the development of deucravacitinib, an orally administered selective TYK2 inhibitor. AREAS COVERED The aim of this manuscript is to review current literature on the effectiveness and safety of deucravacitinib in psoriasis to offer readers a wide perspective. The current English literature was analyzed using the PubMed, Google Scholar, Embase, Cochrane Skin, and clinicaltrials.gov databases, selecting the most relevant manuscripts. EXPERT OPINION Deucravacitinib appears to be an innovative weapon for the management of moderate to severe psoriasis. Despite its efficacy and safety profiles have been revealed by RCTs, real-life data are still scant. Certainly, deucravacitinib broadens the range of therapeutic alternatives for psoriasis patients, thus enhancing the holistic and personalized approach required for the treatment of this disease.

Abstract
PURPOSE Undeniably, in the last 2 decades, surgical approaches in the field of abdominal wall repair have notably improved. However, the best approach to provide a durable repair with low morbidity rate has yet to be determined. The purpose of this study is to outline our long-term results following the Transverse Abdominis Release (TAR) approach in patients with complex ventral hernias, focusing on the incidence of recurrence and overall patient satisfaction following surgery. METHODS This is a retrospective study on 167 consecutive patients who underwent TAR between January 2015 and December 2021 for primary or recurrent complex abdominal hernias. Of these, 117 patients who underwent the open Madrid approach with the use of a double mesh (absorbable and permanent synthetic mesh) were selected and analyzed. A quality of life questionnaire (EuraHS QoL) comparing the preoperative and the postoperative status was administered. RESULTS Between January 2015 and December 2021, we successfully treated 117 patients presenting with complex ventral defects using the double mesh technique (absorbable and permanent synthetic mesh). Of these, 26 (22.2%) were recurrent cases. At a median follow-up period of 37.7 months, there had been 1 (0.8%) case of recurrence and 8 cases (6.8%) of bulging. The QoL score was significantly improved when compared to the preoperative status in terms of cosmesis, body perception, and physical discomfort. CONCLUSIONS The Madrid approach for posterior component separation is associated with both a low perioperative morbidity and recurrence rate. In accordance with other studies, we demonstrated that the TAR with reconstruction according to the Madrid approach provides excellent results in the treatment of complex abdominal wall hernias, even at long-term follow-up.

Abstract
INTRODUCTION Generalized pustular psoriasis (GPP) is a rare form of psoriasis (less of 1% of cases). Currently, GPP is recognized as a clinical entity, distinguished from plaque psoriasis. However, there are not guidelines for GPP management and treatments are often derived from plaque psoriasis. Therefore, conventional systemic drugs are usually used as first-line treatment options, and biologics are still used off label. Recently, spesolimab, an anti-IL36 receptor humanized IgG1 monoclonal antibody, has been specifically approved for GPP disease, revolutionizing treatment scenario. AREAS COVERED The aim of this review is to investigate current literature on the use of spesolimab for GPP management to underline its potential role in GPP and offer a current clinical perspective. Literature research using the Google Scholar, Pubmed, Embase, Cochrane Skin, and clinicaltrials.gov databases was performed, selecting the most relevant manuscripts. EXPERT OPINION Spesolimab is efficacious and has a consistent and favorable safety profile in patients presenting with a GPP flare. However, despite excellent results in terms of safety and efficacy have been reported by both clinical trials and very limited real-life experiences, long-term data, especially in flare-up prevention, are scant. Thus, while the available data are encouraging, further research is warranted to understand the efficacy, safety, and long-term outcomes associated with spesolimab treatment in GPP.

Abstract
Landslides represent a severe geohazard in many countries. The availability of inventories depicting the spatial and temporal distribution of landslides is crucial for assessing landslide susceptibility and risk for territorial planning or investigating landscape evolution. Nevertheless, these inventories are usually affected by limitations due to their nonpublic availability and inhomogeneities in characterization and mapping. Such problems are fully recognizable by the analysis of the multiple landslide inventories of the Campania region, which is one of the Italian regions with the highest exposure to landslide hazard and risk. On this basis, a revised Landslide Inventory of the Campania region (LaICa), resulting from the processing of multiple existing landslide inventories, has been reconstructed. It aims to (i) provide a new geodatabase that is able to overcome issues derived from the coexistence of multiple inventories and (ii) provide a methodological paradigm able to support the reorganization of existing official inventories. The implication of LaICa, with its 83,284 records, will possibly improve the assessment of landslide susceptibility and then reassess the related risk.

Abstract
Urticaria is a disease characterized by wheals and/or angioedema. Chronic spontaneous urticaria (CSU) occurs for longer than 6 weeks and appears independently of any identifiable exogenous stimulus. During the vaccination campaign for Coronavirus disease 2019 (COVID‐19) pandemic, several cutaneous adverse events have been described, among which urticaria lasting less than 6 weeks (acute urticaria, AU). AU due to vaccines can be IgE or non‐IgE mediated; the former typically develop within 4 h of drug exposure, the latter occurs later and the mechanism is unclear. In this retrospective study we analyzed the frequency and clinical characteristics of urticaria occurring after COVID‐19 vaccine (post‐vaccination urticaria relapse) in adult CSU patients treated with antihistamine and omalizumab, and in clinical remission.

Abstract
PURPOSE The aim of this study is to present our innovative robotic approach for the treatment of rectus diastasis with concurrent primary or incisional ventral hernias. METHODS We performed 45 r-TARRD repairs for symptomatic rectus diastasis with concomitant associated ventral/incisional umbilical and/or epigastric hernias between January 2019 and January 2020. Data on patient demographics, type of hernia, operative time, complications, recurrence rate, and hospital stay were retrospectively analyzed. Follow-up was scheduled at 1, 6 months, and 1 year after surgery. RESULTS 45 patients (13 M, 32 F) underwent r-TARRD repair. Mean age was 54.8 years (range 31-68) and mean BMI was 26.74 kg/m2 (range 21.1-31). Mean ASA was 2.2 (range 1-3). In all patients we used a polypropylene mesh 25 × 15 cm, properly shaped. Mean operative time was 192 min (range 115-260). Mean hospital stay 4.2 days (range 2-7). No conversion to laparoscopy or open surgery and no major complications occurred. At 1-month follow-up one mesh infection (2.22%) was observed and it was treated conservatively. Four recurrences (8.88%) were reported at 1-year follow-up. CONCLUSIONS Robot-assisted TARRD repair is conceived as a novel alternative minimally invasive procedure for RD with concurrent midline defects ensuring a primary fascial defect closure and mesh implantation in a sublay position with a wide overlap. It is important to better evaluate the suture that should be used to perform the repair, and multicenter studies with standardization of patient's demographics, RD characteristics, and long-term follow-up outcomes are mandatory to assess the effectiveness and durability of r-TARDD repair.

Abstract
PURPOSE Reinforced prosthetic crural repair is particularly indicated for giant hiatal hernias. The rationale is to reduce the recurrence rate in the long term. The aim of our study is to evaluate the outcomes of laparoscopic giant hiatal hernia repair using a biosynthetic mesh. METHODS We retrospectively analyzed 44 patients who underwent laparoscopic mesh-reinforced hiatal closure and fundoplication using a biosynthetic material. Inclusion criterion was large hiatal defects (> 5 cm). Follow-up was scheduled at 6, 12 and 36 months after surgery. RESULTS 44 patients (29F) with a mean age of 62 years (range 14-85) and mean of BMI 24.5 kg/m2 (range 21-29) underwent successful laparoscopic repair. Twenty-six (59.1%) patients had Nissen-Rossetti fundoplication, whereas 18 (40.9%) had Toupet fundoplication. Six-month questionnaire for the evaluation of symptoms was available for 43 patients (97.7%) and for 40 (90.9%) patients at 12 and 36 months. Mean preoperative symptoms score analysis was 1.68 ± 0.73. Mean scores at each follow-up time were significantly improved compared to baseline (p > 0.05). Barium swallow was available in 37 patients (84.1%) at 1 year after surgery. Radiologic recurrence was observed in two patients (4.5%). No patient had symptoms attributable to recurrence or required revisional surgery. There were no mesh-related complications at 3 years follow-up. CONCLUSIONS The use of biosynthetic mesh for crural reinforcement is associated with a low incidence of mesh-related complications and with a reasonably low recurrence rate (4.5%) at 36 months. However, additional data with longer follow-up are needed to determine long-term safety and efficacy.

Abstract
Continuous monitoring of landslides is of basic importance for understanding their behavior, defining their 3D geometry, and providing a basis for early warning purposes. While a number of instrumentations can be used for tracking surface displacement, only automatic or fixed multi-module inclinometers can be used for continuous monitoring of displacement at depth, providing valuable information for landslide geometry reconstruction. Since these instruments are very expensive, thus rarely used, a low-cost and multi-module fixed inclinometer for continuous landslide monitoring has been developed. In this paper, the electronics of the system, including sensor characteristics and optimization, controlling software, and structure are presented. For system development, a single module prototype was first developed and tested in the field to ensure sufficient measuring performance. Subsequently, the multi-module system was designed, assembled, and tested in controlled conditions. Test results indicate the good performance of the system with a displacement measuring accuracy of 0.37% of the length of the inclinometer chain. The linearity test indicates the high linearity of the measures, especially in the range ±20°, which is the typical operating range of such kinds of instrumentations. The thermal efficiency test indicates the high efficiency of the system in preventing measuring errors caused by thermal drifting.

Abstract
In this work, a low-cost, open-source and replicable system prototype for thermal analysis of low-cost Micro Electro-Mechanical Systems (MEMS) Inertial Measurement Unit (IMU) sensors in tilt measurement perspective is presented and tested. The system is formed of a 3D printed frame, a thermal cell consisting in a Peltier element mounted over a heat sink, and a control and power system. The frame is designed to allow the independent biaxial tilting of the thermal cell through two servomotors. The control board is formed by an Arduino® and a self-made board including a power drive for controlling the thermal unit and servomotors. We tested the chamber analyzing the behavior of multiple MEMS IMU onboard accelerometers suitable for measuring tilt. Our results underline the variability of the thermal behavior of the sensors, also for different sensor boards of the same model, and consequently the need for the adoption of a thermal compensation strategy based on thermal analysis results. These data suggesting the need for the analysis of the thermal behavior of MEMS-based sensors, indicate the potential of our system in making low-cost sensors suitable in medium-to-high precision monitoring applications.

Abstract
Low-cost MEMS accelerometers have the potential to be used in a number of tilt-based monitoring applications but have the disadvantage of being very sensitive to temperature variation (thermal drift). In this paper, we analyze the thermal behavior of a low-cost sensor in the range -10 to +45 °C in order to provide a simple compensation strategy to mitigate this problem. For sensor analysis, we have developed a miniaturized thermal chamber, which was mounted on a tilting device to account for tilt angle variation. The obtained raw data were used to construct low degree polynomial equations that by relating the measurement error induced by thermal drift (i.e., acceleration residuals) to temperature and inclination (of each specific axis), can be used for thermal compensation. To validate our compensation strategy, we performed a field monitoring test and evaluated the compensation performance by calculating RMS errors before and after correction. After compensation, the RMS errors calculated for both the X and Y axes decreased by 96%, indicating the potential of using a simple set of equations to solve common drawbacks that currently make low-cost MEMS sensors unsuitable for tilt-based monitoring applications.

Abstract
PURPOSE Giant paraesophageal hernias (GPEH) are relatively uncommon and account for less than 5% of all primary hiatal hernias. Giant Secondary GPEH can be observed after surgery involving hiatal orifice opening, such as esophagectomy, antireflux surgery, and hiatal hernia repair. Surgical treatment is challenging, and there are still residual controversies regarding the laparoscopic approach, even though a reduced morbidity and mortality, as well as a shorter hospital stay have been demonstrated. METHODS A Pubmed electronic search of the literature including articles published between 1992 and 2016 was conducted using the following key words: hiatal hernia, paraesophageal hernias, mesh, laparoscopy, intrathoracic stomach, gastric volvulus, diaphragmatic hernia. RESULTS Given the risks of non-operative management, GPEH surgical repair is indicated in symptomatic patients. Technical steps for primary hernia repair include hernia reduction and sac excision, correct repositioning of the gastroesophageal junction, crural repair, and fundoplication. For secondary hernias, the surgical technique varies according to hernia type and components and according to the approach used during the first surgery. There is an ongoing debate regarding the best and safest method to close the hiatal orifice. The laparoscopic approach has demonstrated a lower postoperative morbidity and mortality, and a shorter hospital stay as compared to the open approach. A high recurrence rate has been reported for primary GPEH repair. However, recent studies suggest that recurrence does not reduce symptomatic outcomes. CONCLUSIONS The laparoscopic treatment of primary and secondary GPEH is safe and feasible in elective and emergency settings, especially in high-volume centers. The procedure is still challenging. The main steps are well defined. However, there is still room for improvement to lower the recurrence rate.

Abstract
We created a Web catalogue of approved telemedicine systems that authoritative Italian research bodies had made available for more general use. The evaluation process was divided into two stages: (1) classification of the telemedicine systems and rough preliminary evaluation; (2) assessment of the telemedicine products and services. The scoring method was applied to four well-known telemedicine systems that had been tested in health-care settings: an echocardiology teleconsulting and analysis system; a ward nursing management system; a virtual cooperative system for the management of oncology patients and a telepathology system based on remotely controlled microscopy. After technical revision during the standardization/qualification process, the applications were transferred successfully to eight new health-care facilities. The methodology achieved the main goal of providing effective tools, such as a set of quality control procedures for telemedicine and telehealth projects and a Web catalogue of telemedicine applications with a standardized level of quality, available to all interested parties.

Abstract
BACKGROUND AND AIMS While in the past, thoracotomy represented the traditional surgical approach for the treatment of epiphrenic diverticula, actually mini-invasive approach seems to be the preferred treatment as many series have been published in the recent years. This article describes the authors' experience with the laparoscopic approach for performing diverticulectomy, myotomy, and Nissen-Rossetti fundoplication. MATERIAL AND METHODS From 1994 to 2010, 21 patients (10 men and 11 women), mean age 58.5 years (range 45-74 years), with symptomatic epiphrenic diverticulum underwent laparoscopic diverticulectomy, myotomy and Nissen-Rossetti fundoplication. RESULTS The mean operative time was 135 min (range = 105-190 min). Mean hospital stay was 14.2 days (range = 7-25 days). In 5 patients (23.8%), a partial suture staple line leak was observed. Conservative treatment achieved leak resolution in all the cases. One patient (4.8%) died of a myocardial infarction in the postoperative period. After a mean clinical follow-up period of 78 months (range = 6-192 months), excellent or good outcome was referred with no dysphagia in 16 patients (80%) and only mild occasional dysphagia in 4 patients (20%). CONCLUSIONS Surgical treatment of epiphrenic diverticula remains a challenging procedure also by mini-invasive approach, with major morbidity and mortality rates. For this reason, indications must be restricted only to selected and symptomatic patients in specialized centers.

Abstract
BACKGROUND In this prospective non-randomized observational cohort study we evaluated: the feasibility and effectiveness of primary umbilical hernia repair with open tension-free and sutureless technique using a porcine small intestinal submucosa (Surgisis) prosthesis, the quality of the treatment in terms of reduction of postoperative discomfort and the complications at early and long-term follow-up. METHODS Thirty-six consecutive patients, mean age 45.25 +/- 12.19 years, affected by primary umbilical uncomplicated hernia with a defect size < or = 3 cm, were treated in a day-surgery setting. A tailored flat Surgisis graft was used to ensure an overlap of at least 2 cm; in all patients the mesh was fixed by fibrin glue. Collected data included: visual analogic scale (VAS) pain scores at 24 hours, 72 hours, and 7, 15, and 30 days and number of analgesic medications after operation, complications rate, the quality of life measured by Short Form 36 health survey questionnaire (SF-36) before the operation and at long term follow-up. RESULTS The mean follow-up time was 5.6 +/- 1.4 years. Postoperative pain was low: the mean visual analogic scale (VAS) scores were 2.8 at 24 h, 1.8 at 72 h, and 0.9, 0.3, and 0.04 at 7, 15, and 30 days, respectively. 77.8% of the patients (28/36) did not use any analgesic drugs. Seroma was reported in 13.8% of the patients (5/36); there were no hematomas, infection, chronic pain and no major complications or mortality (< or = 30 days). Recurrence rate was 2.8% (1/36). Patient satisfaction showed a significant improvement in all SF-36 domain scores (P < 0.001). CONCLUSIONS The biologic mesh seems to be a safe and reliable device for repairing primary umbilical hernia with high patient comfort, even if not yet an alternative to synthetic mesh.

Abstract
We evaluated the ability of the combination disk test (CDT) and the Modified Hodge Test (MHT) to discriminate between various carbapenemase-producing Pseudomonas aeruginosa isolates (KPC, n = 36; metallo-β-lactamase (MBL), n = 38) and carbapenemase non-producers (n = 75). For the CDT, the optimal inhibitor concentrations and cut-off values were: 600 μg of 3-aminophenylboronic acid (APB) per disk (an increment of ≥4 mm), 1000 μg of dipicolinic acid (DPA) per disk (an increment of ≥5 mm) and 3000 μg of cloxacillin per disk (an increment of ≥3 mm). APB had excellent sensitivity (97%) and specificity (97%) for the detection of KPC enzymes. DPA detected MBL enzymes with a sensitivity and specificity of 97% and 81%, respectively. The MHT resulted in a low sensitivity (78%) and specificity (57%). The CDT could be very useful in daily practice to provide fast and reliable detection of KPC and MBL carbapenemases among P. aeruginosa isolates.

Abstract
Fluoroquinolone resistance is a growing problem that has only recently emerged in S. agalactiae. Between 2005-2007, WHONET--Argentina network evaluated levofloxacin susceptibility in 1128 clinical S. agalactiae isolates, 10 (0.9%) of which proved to be resistant. Nine of them had come from 5 hospitals (in Buenos Aires City and 4 Argentinean provinces) and recovered from urine (n=7) and vaginal screening cultures (n=2). Three strains were also resistant to macrolides, lincosamides and B streptogramins due to the ermA gene. All nine fluoroquinolone-resistant isolates bore the same two mutations, Ser79Phe in ParC and Ser81Leu in GyrA proteins. Genetic relationships were analyzed by Apal-PFGE and two clones were determined, A (n=6) and B (n=3). To our knowledge, these are the first fluoroquinolone-resistant S. agalactiae isolates detected in Latin America.

Abstract
INTRODUCTION The aim of this trial was to compare lorazepam with non-benzodiazepine medications such as pregabalin and tiapride in the treatment of alcohol withdrawal syndrome (AWS). These drugs were chosen for their inhibitorial effects on the hypersecretion of neurotransmitters usually observed in AWS. Craving reduction and improvement of psychiatric symptoms were the secondary end-points. METHODS One hundred and ninety subjects affected by current alcohol dependence were considered consecutively: 111 were enrolled and divided into three groups of 37 subjects each. Within a treatment duration of 14 days, medication was given up to the following maximum doses (pregabalin 450 mg/day; tiapride 800 mg/day; lorazepam 10 mg/day). Withdrawal (CIWA-Ar), craving [visual analogue scale (VAS); Obsessive and Compulsive Drinking Scale (OCDS)], psychiatric symptoms [Symptom Check List 90 Revised (SCL-90-R)] and quality of life (QL-index) rating scales were applied. RESULTS On the CIWA-Ar score, all the groups showed a significant reduction between times (P < 0.001) with a higher reduction for the pregabalin group (P < 0.01) on items regarding headache and orientation. Retention in treatment was lower in the tiapride group (P < 0.05), while the number of subjects remaining alcohol free was higher in the pregabalin group (P < 0.05). Significant reduction between baseline and the end of the treatment was found in all the groups at the OCDS and the VAS for craving, at the SCL-90-R and QL-index (P < 0.001). DISCUSSION All the medications in the trial showed evidence of safety and efficacy in the treatment of uncomplicated forms of AWS, with some particular differences. The efficacy of pregabalin was superior to that of tiapride, used largely in research trials and, for some measures, to that of the 'gold standard', lorazepam. Accordingly, pregabalin may be considered as a potentially useful new drug for treatment of AWS, deserving further investigation.

Abstract
Introduction:Aim of this randomised, parallel, placebo-controlled group trial was to compare oxcarbazepina and topiramate with placebo on alcohol drinking indices. Craving and psychiatric simptomatology have also been investigated.Methods:This randomised, parallel, placebo-controlled psychopharmacology trial studied 60 patients, consecutively recruited, meeting clinical criteria for Alcohol Dependence (DSM-IV). After detoxification, subjects were assigned to flexible doses of oxcarbazepine (n=20), or topiramate (n=20) or placebo (n=20). Withdrawal symptomatology was determined by the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) and the level of craving for alcohol was evaluated by a 10-cm Visual Analogue Scale (VAS) and the Italian -version of the Obsessive and Compulsive Drinking Scale (OCDS). Psychiatric symptoms were evaluated with the Symptom Check List 90 Revised (SCL-90 R).Results:Non-benzodiazepine anticonvulsants have been shown to be efficacious treatments for the prevention of alcohol relapse although the FDA has yet approved none of these agents. During the congress the main results of this study will be presented.Conclusions:To our knowledge, this is the first randomised, parallel, placebo-controlled group study to evaluate the efficacy of oxcarbazepine and topiramate compared in alcohol dependent patients. The data of this pilot clinical study suggest and investigate a possible role for the anticonvulsants agents in the treatment of alcohol dependent patients.

Abstract
Use of mean-field annealing theory is proposed for solving the phase-unwrapping (PU) problem. PU is formulated as a constrained optimization problem for the field of integer corrections to be added to the wrapped gradient field. A deterministic algorithm is described to provide an approximation of the average of the correction field over the global minima of the cost function. The proposed algorithm can be applied for any choice of the cost function. Using a cost function based on second-order differences, we obtain results close to those from simulated annealing and spend less computational time.

Abstract
A new, to our knowledge, algorithm for the phase unwrapping (PU) problem that is based on stochastic relaxation is proposed and analyzed. Unlike regularization schemes previously proposed to handle this problem, our approach dispells the following two assumptions about the solution: a Gaussian model for noise and the magnitude of the true phase-field gradient's being less than pi everywhere. We formulate PU as a constrained optimization problem for the field of integer multiples of 2pi, which must be added to the wrapped phase gradient to recover the true phase gradient. By solving the optimization problem using simulated annealing with constraints, one can obtain a consistent solution under difficult conditions resulting from noise and undersampling. Results from synthetic test images are reported.

Abstract
We describe a system of two groups of multiwire proportional chambers and its special purpose interface used in the Single Arm Spectrometer (SAS) facility at Fermilab. The first set measures the coordinates of the fast particle going into the spectrometer arm with a space resolution down to +/-0.5 mm. The second set, close to the target, measures the multiplicity and angular distributions of charged particles coming from the interaction. The chambers of this set have three sensitive planes with wires at 120 degrees in the same gas volume to measure three coordinates for each physical point, two readout channels per wire to minimize the inefficiency due to the very high flux and insensitive regions at the center of the chambers where they are crossed by the beam.
