Erythrodermic psoriasis in a dialyzed patient successfully treated with Secukinumab.

Erythrodermic psoriasis is a severe, life-threatening condition with additional complications, when occurring in hemodialyzed patients, as the majority of treatments are contraindicated. A 44-years-old man, of Philippine origins, with a 15-years-history of psoriasis treated with cyclosporine developed progressive hypertension and renal insufficiency. Despite drug dismission, renal function worsen to end-stage, and hemodialysis was necessary three times a week. Phototherapy was not able to control the skin condition, progressing to erythroderma, and after nephrology consultation, the patient consent to the off-label secukinumab treatment, at the standard regimen (300 mg subcutaneously once weekly at weeks 0-4 followed by 300 mg every 4 weeks). Seven days after the first injection, a rapid improvement was noted, with the psoriasis area severity index (PASI) score passing from 31.5 to 17.6. At the 52-week-follow-up visit, the patient was completely clarified, without any side effects. The case supports secukinumab effectiveness and safety in difficult patients, including erythrodermic psoriasis with end-stage renal failure, as drug plasma levels seem not to be affected by hemodialysis. Results are rapidly achieved, and long term maintained, with the additional advantage of a very comfortable monthly administration.

Clinical efficacy, speed of improvement and safety of apremilast for the treatment of adult Psoriasis during COVID-19 pandemic.

Time to improvement is a crucial characteristic for effective treatments of chronic inflammatory conditions, such as psoriasis. Apremilast is a recently approved drug, belonging to the small molecule phosphodiesterase 4 inhibitors, whose optimal safety and efficacy profile is somewhat affected by slow activity rate in clinical trials. Real world case series are suggesting a more consistent improvement, and with this additional personal investigation on 48 patients, we signal that 58% of patients achieved Psoriasis Area and Severity Index (PASI) 50, and 19% PASI 75 improvement in the first 8 weeks of treatment. Results at 16-week are remarkable, with overall 55% of patients achieving PASI 75, 21% PASI 90 and 14% PASI 100. Only 8 patients (18, 6%) had slightly improved, although satisfied with the regimen, and determined to continue. Noteworthy, our population was rather problematic in terms of comorbidities (86%), and resistance to other treatments, with only 28% naïve to systemics, including biologics. Moreover, the observation period includes the Italian outbreak of COVID-19 epidemic, and further information on apremilast safety are provided, no one of the patients having stopped treatment. In such a critical period, the apremilast satisfactory speed of therapeutic response in a real-world setting has further strengthens patient's compliance to remain safely at home, which is the best strategy to limit contagion.

Successful guselkumab treatment in a psoriatic patient affected with Cornelia de Lange syndrome, and prosecution during the COVID-19 pandemic.

Psychomotor delay and intellectual disability are potential limitations in psoriasis management, due to low compliance, and strict dependence from caregivers intervention. We report our successful experience with a 58-year-old woman, who was genetically affected by Cornelia De Lange syndrome, which causes intellectual disability and psychomotor disorders. The patient had been already treated with topical and traditional therapies, without any clinical benefits. Eventually, she adhered to guselkumab treatment. The compliance was excellent, significant improvements were observed after only 3 months of treatment, without adverse effects. During follow-up, the COVID-19 pandemic address concern on the possible increased risk of infection due to immunosuppression. In agreement with current Italian recommendations, risk and benefits profile was discussed with the patient's legal tutor and the decision to continue the treatment was taken. Psoriasis complete clarification was maintained during the most difficult period of the Italian outbreak, allowing the patient to remain safely at home.

Extralaryngeal branching of the recurrent laryngeal nerve: a meta-analysis of 28,387 nerves.

INTRODUCTION: The recurrent laryngeal nerves (RLN) are branches of the vagus nerve that go on to innervate most of the intrinsic muscles of the larynx. Historically, the RLN has been considered to branch after it enters the larynx, but numerous studies have demonstrated that it often branches before. The wide variability of this extralaryngeal branching (ELB) has significant implications for the risk of iatrogenic injury. We aimed to assess the anatomical characteristics of ELB comprehensively. METHODS: Articles on the ELB of the RLN were identified by a comprehensive database search. Relevant data were extracted and pooled into a meta-analysis of the prevalence of branching, branching pattern, distance of ELB point from the larynx, and presence of positive motor signals in anterior and posterior ELB branches. RESULTS: A total of 69 articles (n = 28,387 nerves) from both intraoperative and cadaveric modalities were included in the meta-analysis. The overall pooled prevalence of ELB was 60.0 % (95 % CI 52.0-67.7). Cadaveric and intraoperative subgroups differed with prevalence rates of 73.3 % (95 % CI 61.0-84.0) and 39.2 % (95 % CI 29.0-49.9), respectively. Cadavers most often presented with a ELB pattern of bifurcation, with a prevalence of 61.1 %, followed by no branching at 23.4 %. Branching of the RLN occurred most often at a distance of 1-2 cm (74.8 % of cases) prior to entering the larynx. A positive motor signal was most often noted in anterior RLN branches (99.9 %) but only in 1.5 % of posterior branches. CONCLUSIONS: The anatomy of the RLN is highly variable, and ELB is likely to have been underreported in intraoperative studies. Because of its high likelihood, the possibility of ELB needs to be assessed in patients to prevent iatrogenic injury and long-term postoperative complications.

Population-based analysis of hospitalizations for patients with systemic sclerosis in a West-European region over the period 2001-2012.

The aim of this study was to evaluate systemic sclerosis (SSc) hospitalizations through a retrospective population-based study analyzing administrative data during 2001-2012 in Sardinia, an Italian region with universal Health System coverage. Data on hospital discharge records with ICD-9-CM code for SSc (710.1) were obtained from the Department of Health and Hygiene. Two-tailed Cochran-Armitage test for trend was applied to analyze the annual trend for primary and non-primary discharge diagnoses. SSc prevalence was also estimated. This study included 4981 hospitalizations in 736 patients (84.8 % women). Hospitalizations with SSc as primary diagnosis were 3631 (72.9 %). Their annual number significantly increased during study period, from 143 in 2001 to 390 in 2012. Annual trend analysis revealed statistically significant increase in number and percentage of interstitial lung disease (p < 0.0001), pulmonary arterial hypertension (p < 0.0024), osteoporotic fragility fractures (p < 0.0001), ulcers, and gangrene (p = 0.0037) as non-primary diagnoses associated with SSc. Although the number of admissions with SSc as non-primary diagnosis showed a slight reduction during the study period, the annual number and percentage of admissions with respiratory failure (p = 0.0016) and congestive heart failure (p < 0.0001) as primary diagnosis showed a significant upward trend. Admissions for intravenous infusion, mainly day-hospital, accounted for 19.1 % of all hospitalizations for SSc and showed a significant (p = 0.0002) upward trend in 2001-2012. The 2012 SSc prevalence in Sardinia was estimated to be 34.8 per 100,000 inhabitants. Hospital care utilization for SSc is changing over time, showing increased hospitalizations aimed at the early recognition and treatment for the major manifestations and complications of SSc.

Evidence of an effect of statins on lesions originating from dental infection. A retrospective clinical investigation.

BACKGROUND: Apical periodontitis (AP) is an inflammatory dental disease caused by bacterial infections of the endodontic system. The correlation between AP and cardiovascular diseases. (CVD) has been consistently investigated. Statins are a class of drugs that are used to treat hypercholesterolemia and prevent atherosclerotic vascular diseases. They have other beneficial pleiotropic effects such as anti-inflammatory, antithrombotic, and antioxidant activities. The aim of this study was to evaluate the oral health status and prevalence of AP in patients treated with statins (Group S) in comparison with untreated patients (Group C) to understand whether the anti-inflammatory action of these drugs can influence the prevalence of AP. METHODS: The records of seventy-nine patients (43 men and 36 women, mean age 68 ± 11 years, 1716 teeth) treated with statins and referred to the University clinic for dental evaluation were reviewed. Seventy patients free from systemic diseases and without therapy (39 men and 31 women, mean age 62 ± 9 years, 1720 teeth) constituted the control group. All subjects underwent complete oral, dental, and radiographic examinations to determine the presence and severity of AP. Periapical index (PAI) and decayed, missed, and filled teeth (DMFT) scores were obtained. RESULTS: AP was significantly less common in Group S (22,8%) than in Group C (50%) (P < 0.05). Furthermore, the mean value of the qualitative rank of the severity of AP (PAI score) was higher in Group C than in Group S (P ≤ 0.05). CONCLUSIONS: Our results suggest that statins can attenuate the prevalence of AP, which is associated to CVD.

Non-surgical treatment of hidradenitis suppurativa: the role of cryotherapy.

Background: Hidradenitis suppurativa is a chronic and recurrent inflammatory disease with a great impact on a patient's quality of life, due to the painful involvement of very sensitive areas, such as the groin, mammary area, and genitals, with malodourous discharge. Multiple treatment options are available; however, no single treatment is effective for all patients, and usually, a combination of medical therapy with various surgical and physical procedures is provided. Cryotherapy is not a routine technique to treat HS, although usually available in the majority of medical clinics, and is cheaper than laser and surgical treatments. The aim of this study was to evaluate the effectiveness of cryotherapy on persistent HS nodules, to reduce the burden of local disease. Materials and methods: Retrospective observational study in all patients treated with liquid nitrogen cryotherapy for persistent nodules of hidradenitis suppurativa in the last 2 years, with at least 6 months of follow-up after the procedure. Disease severity was assessed with Hurley staging and sonographic staging according to SOS-HS (18 MHz probe, Esaote-MyLab™). The results were scored with a 0-3 points scale, as complete remission (3), partial response (2 to 1), or no response (0), after one session of treatment. Local cleansing and antiseptic treatment after the procedure was the same as previously performed in each patient, not to influence recovery. Results: In total, 23 patients were included, with a total of 71 persistent nodules treated with a single cryotherapy session. The treatment has been effective in 63 out of 71 nodules treated (88.7%), and the patients attested that they recommend the treatment, the discomfort during recovery was minimal, and the management was not different from daily routine. Persistence was considered as having a failure rate (11.3% overall) and occurred in 7.5% of the nodules of the axillary region, 18.2% on the groin, and 11.2% for nodules of the gluteal region. Conclusion: Cryotherapy is a simple and effective procedure for the treatment of persistent nodules of HS not responding to medical therapy, and it is a valid alternative to local surgery or laser ablation.

Management of periprosthetic knee joint infections: focus on the role of Nuclear Medicine (v2).

Background: When faced with a painful knee replacement, ruling out infection is mandatory to set the correct therapeutic approach. However, it is not always easy, especially in subclinical/chronic infections. A multidisciplinary approach is necessary to assess in the most correct way each case of suspected periprosthetic knee joint infection. This review explores the role of nuclear medicine investigations in the management of periprosthetic knee infections and their proper use within a multidisciplinary pathway. Methods: A PubMed search was conducted selecting studies from the past 10 years. Results: Triphasic bone scintigraphy has high sensitivity (93%) but poor specificity (56%) for periprosthetic joint infections of the knee, with a high negative predictive value (NPV), ranging from 96% to 100%. Consequently, a negative bone scan is useful in ruling out infection. In contrast, radiolabeled leukocyte scintigraphy is characterized by a sensitivity of 85.7-93%, specificity of 93.6-100%, diagnostic accuracy of 92.6-98%, NPV of 93-97.8%, and positive predictive value (PPV) of 66.7-100%. By adding a tomographic acquisition with hybrid single-photon emission computed tomography combined with computed tomography technique (SPECT/CT), the diagnostic accuracy increases. Because 18F-fluorodeoxyglucose (FDG) accumulates at both sites of inflammation and infection, FDG positron emission tomography (PET/CT) shows low specificity. Conclusions: A common decision-making process in the diagnosis of periprosthetic joint infection is not yet validated and multidisciplinary integration is mandatory. In this context, nuclear medicine can contribute decisively.

Left atrial remodeling in heart failure: the role of sphericity index (the SPHERICAT-HF study).

Left atrial sphericity index (LASI) is an echocardiographic index easily obtained; its use in patients with heart failure (HF) has never been investigated so far. This single-centre study aimed to investigate the usefulness of LASI in an unselected cohort of patients hospitalized for acute HF, and its potential correlation with the amino-terminal portion of pro-B-type natriuretic peptide (NT-proBNP) levels and with New York Heart Association (NYHA) functional class. Ninety-four consecutive HF patients underwent a transthoracic echocardiogram with a detailed study of the left atrium (LA) including LASI (calculated from the apical four-chamber view as the ratio between the transverse and longitudinal diameters), and blood tests (including NT-proBNP) on the same day. Median age was 75.5 (interquartile range-IQR 62-82) years and 55% were males, 58.5% had a NYHA class III-IV, and median NT-proBNP was 3284 (IQR 1215-7055) pg/ml. The LA was dilated in 94%, and median biplane LA volume index was 62 ml/m2. Patients with advanced NYHA class showed more advanced LA remodeling. Mean LASI was 0.78 ± 0.09 and did not correlate with NT-proBNP levels (r 0.03; p 0.75) or with patient NYHA class (R2 0.011; p 0.287). None of the echocardiographic indices of LA structural and functional remodeling proved to be independently associated with a high NYHA class on multivariate regression analysis. In conclusion, LA remodeling is almost invariably present in patients with HF. LASI does not correlate with NT-proBNP levels or with NYHA functional class. Further studies are needed to describe the complex patterns of atrial remodeling in HF.

Extended totally extraperitoneal Rives-Stoppa (eTEP-RS) technique for ventral hernia: initial experience of The Wall Hernia Group and a surgical technique update.

The enhanced-view extended totally extraperitoneal (eTEP) approach for ventral hernia repair is a novel surgical technique. We present the results from the initial experience with eTEP repair Rives-Stoppa (eTEP-RS) at two Italian centers, and we provide an update on this approach. Between December 2018 and July 2020, 19 patients suffering from ventral hernia were treated with the eTEP-RS. Patients' characteristics, operative details, and complications were analyzed. The median follow-up time was 16 (range 6-24) months. Thirteen (68.4%) patients with ventral incisional hernias and 6 (31.6%) with primary ventral hernia underwent an eTEP-RS procedure. The average defect area was 21 cm2 and the prosthesis's average size was 380 cm2. We registered complications in two cases (10.5%); 1 patient had an asymptomatic seroma (Clavien-Dindo grade 1), and another had intestinal obstruction on the 10th postoperative day (Clavien-Dindo grade 3B). The mean hospital stay was 3.9 (range: 2-6) days. There was no hernia recurrence. The eTEP-RS is a feasible and safe approach in ventral hernia repair with minimally invasive surgery. Further studies are needed to define patients' selection and to know long-term outcomes.

Incidental Finding on 11C-Choline-PET/CT of Hepatocellular Carcinoma Recurrence in a Prostate Cancer Patient With Negative Abdominal CT Scan.

A 76-year-old man, who experienced prostate cancer biochemical relapse after 12 years from radical prostatectomy, underwent abdominal CT scan for restaging purposes, negative for metastases, and then C-choline PET/CT. The only finding was an area of focal uptake of radiotracer between the intestinal loops and the abdominal wall; after resection, the lesion demonstrated to be a metastasis from hepatocellular carcinoma (HCC), for which the patient had undergone liver resection 2 years earlier. This case proves that abnormal foci of C-choline uptake in the peritoneum in HCC patients have to be kept in mind as possible sites of HCC-metastases.

Efficacy and safety of a single switch from etanercept originator to etanercept biosimilar in a cohort of inflammatory arthritis.

AntiTNF-α biosimilars are broadly available for the treatment of inflammatory arthritis. There are a lot of data concerning the maintenance of clinical efficacy after switching from originators to biosimilars; therefore, such a transition is increasingly encouraged both in the US and Europe. However, there are reports about flares and adverse events (AE) as a non-medical switch remains controversial due to ethical and clinical implications (efficacy, safety, tolerability). The aim of our work was to evaluate the disease activity trend after switching from etanercept originator (oETA-Enbrel) to its biosimilar (bETA-SP4/Benepali) in a cohort of patients in Turin, Piedmont, Italy. In this area, the switch to biosimilars is stalwartly encouraged. We switched 87 patients who were in a clinical state of stability from oETA to bETA: 48 patients were affected by Rheumatoid Arthritis (RA),26 by Psoriatic Arthritis (PsA) and 13 by Ankylosing Spondylitis (AS).We evaluated VAS-pain, Global-Health, CRP, number of swollen and tender joints, Disease Activity Score on 28 joints (DAS28) for RA, Disease Activity in Psoriatic Arthritis (DAPSA) for PsA, Health Assessment Questionnaire (HAQ) and Health Assessment Questionnaire for the spondyloarthropathies (HAQ-S),Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for AS patients. 11/85 patients (12.6%) stopped treatment after switching to biosimilar etanercept. No difference was found between oETA and bETA in terms of efficacy. However, some arthritis flare and AE were reported. Our data regarding maintenance of efficacy and percentage of discontinuation were in line with the existing literature.

The prevalence and morphometry of an accessory spleen: A meta-analysis and systematic review of 22,487 patients.

BACKGROUND: An accessory spleen (AS) is a lobule of splenic tissue found in ectopic locations. Identification of AS is particularly important in patients with immune thrombocytopenia (ITP) requiring splenectomy as unrecognized AS can later cause refractory symptoms. The AS can also be a source of significant intraabdominal hemorrhage. The aim of this meta-analysis was to systematically analyze the data on the prevalence, number, location, and morphometry of AS. MATERIALS AND METHODS: An extensive search of the major electronic databases was conducted to identify all studies that reported relevant data on the AS. No date or language restrictions were applied. Data on the study type, the prevalence of AS, location, morphometry and number of AS per patient were extracted from the eligible studies and pooled into a meta-analysis. RESULTS: A total of 81 studies (n = 22,487 subjects) were included into the quantitative analysis. The overall pooled prevalence of AS was 14.5% (95%CI: 12.4-16.7), while the pooled prevalence of AS in ITP patients was 16.7% (95%CI: 12.1-21.7). The majority of accessory spleens were located in the splenic hilum (62.1% [95%CI:51.5-76.3]). Moreover, 26% of ITP patients with an AS have more than one. CONCLUSIONS: The findings of this study provide an evidence-based foundation of anatomical knowledge about the AS. Surgeons should take particular caution in identifying an AS, as unnoticed AS during splenectomy can lead to recurrence of hematological diseases or can be a potential source of bleeding in the future.

The Anastomoses of the Recurrent Laryngeal Nerve in the Larynx: A Meta-Analysis and Systematic Review.

OBJECTIVES: The recurrent laryngeal nerve and its branches form a great variety of anastomoses. These nerve communications can alter the innervation patterns of the laryngeal muscles and can affect both the diagnosis and treatment of paralyzed vocal cords. The aim of this study was to assess the prevalence and anatomical characteristics of the laryngeal nerve connections, and to review their function and clinical significance. STUDY DESIGN: Meta-analysis and systematic review. METHODS: The major electronic databases were thoroughly searched to identify all studies reporting data on the anastomoses of the laryngeal nerves. Data on the prevalence of each type of anastomosis were extracted and pooled into a meta-analysis using MetaXL version 3.0 (EpiGear International Pty. Ltd., Wilston, Queensland, Australia). RESULTS: Twenty-two cadaveric studies (n = 1404 hemilarynges) were included in the meta-analysis. The two most common communications were Galen's anastamosis and the arytenoid plexus. The pooled prevalence estimate for Galen's anastamosis was 76.7% (95% confidence interval [CI]: 59.0-90.0), of which the single trunk type was most common (92.3%). The arytenoid plexus had a pooled prevalence estimate of 79.7% (95% CI: 41.1-100). CONCLUSIONS: Owing to the high prevalences and variability of nerve connections in the larynx, detailed anatomical knowledge of these anastomoses can be crucial for the accurate interpretation of laryngoscopy results, reducing iatrogenic injury during surgical procedures, and facilitating the development of novel strategies for treating laryngeal paralyses.

Variable relationship of the recurrent laryngeal nerve to the inferior thyroid artery: A meta-analysis and surgical implications.

BACKGROUND: The relationship between the recurrent laryngeal nerve (RLN) and inferior thyroid artery (ITA) is highly variable and traceable back to embryological life. METHODS: Comprehensive database searches were conducted, followed by judgment of eligibility, assessment, and extraction of data concerning the RLN/ITA relationship. The data were pooled into a meta-analysis and subjected to sex, side-based, geographic origin of study, and study modality subgroup analyses. RESULTS: Seventy-nine studies (n = 14,269 nerves) reported data on the relationship of the RLN to the ITA. The left versus right-sided comparison revealed stark differences: RLNs were predominantly posterior (62.6% vs 37.0%) and anterior (17.2% vs 37.1%) on the left and right sides, respectively. CONCLUSION: Symmetry of neurovascular relationships should not be assumed. Extra care should be taken during procedures on the right side, because the nerves are significantly more likely to present in patterns (anterior and between) associated with greater risk of iatrogenic injury. © 2016 Wiley Periodicals, Inc.

The Reliability of the Tracheoesophageal Groove and the Ligament of Berry as Landmarks for Identifying the Recurrent Laryngeal Nerve: A Cadaveric Study and Meta-Analysis.

Purpose. The aim of this meta-analysis was to provide a comprehensive evidence-based assessment, supplemented by cadaveric dissections, of the value of using the Ligament of Berry and Tracheoesophageal Groove as anatomical landmarks for identifying the Recurrent Laryngeal Nerve. Methods. Seven major databases were searched to identify studies for inclusion. Eligibility was judged by two reviewers. Suitable studies were identified and extracted. MetaXL was used for analysis. All pooled prevalence rates were calculated using a random effects model. Heterogeneity among included studies was assessed using the Chi2 test and the I2 statistic. Results. Sixteen studies (n = 2,470 nerves), including original cadaveric data, were analyzed for the BL/RLN relationship. The RLN was most often located superficial to the BL with a pooled prevalence estimate of 78.2% of nerves, followed by deep to the BL in 14.8%. Twenty-three studies (n = 5,970 nerves) examined the RLN/TEG relationship. The RLN was located inside the TEG in 63.7% (95% CI: 55.3-77.7) of sides. Conclusions. Both the BL and TEG are landmarks that can help surgeons provide patients with complication-free procedures. Our analysis showed that the BL is a more consistent anatomical landmark than the TEG, but it is necessary to use both to prevent iatrogenic RLN injuries during thyroidectomies.

The Non-Recurrent Laryngeal Nerve: a meta-analysis and clinical considerations.

BACKGROUND: The Non-Recurrent Laryngeal Nerve (NRLN) is a rare embryologically-derived variant of the Recurrent Laryngeal Nerve (RLN). The presence of an NRLN significantly increases the risk of iatrogenic injury and operative complications. Our aim was to provide a comprehensive meta-analysis of the overall prevalence of the NRLN, its origin, and its association with an aberrant subclavian artery. METHODS: Through March 2016, a database search was performed of PubMed, CNKI, ScienceDirect, EMBASE, BIOSIS, SciELO, and Web of Science. The references in the included articles were also extensively searched. At least two reviewers judged eligibility and assessed and extracted articles. MetaXL was used for analysis, with all pooled prevalence rates calculated using a random effects model. Heterogeneity among the included studies was assessed using the Chi2 test and the I2 statistic. RESULTS: Fifty-three studies (33,571 right RLNs) reported data on the prevalence of a right NRLN. The pooled prevalence estimate was 0.7% (95% CI [0.6-0.9]). The NRLN was found to originate from the vagus nerve at or above the laryngotracheal junction in 58.3% and below it in 41.7%. A right NRLN was associated with an aberrant subclavian artery in 86.7% of cases. CONCLUSION: The NRLN is a rare yet very clinically relevant structure for surgeons and is associated with increased risk of iatrogenic injury, most often leading to temporary or permanent vocal cord paralysis. A thorough understanding of the prevalence, origin, and associated pathologies is vital for preventing injuries and complications.
