Long-term safety and efficacy of adalimumab in psoriasis: a multicentric study focused on infections (connecting study).

Introduction: This Italian multicenter retrospective study evaluated safety and efficacy of the anti-TNF drug, adalimumab, in a cohort of patients affected by tuberculosis (TB), hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV). Psoriasis is an autoimmune disease affecting around 3% of the Italian population and associated with several comorbidities, including arthritis, cardio-metabolic diseases and depression. In its moderate-to-severe form, psoriasis profoundly impairs quality of life of patients.

High resolution melting profiles (HRMPs) obtained by magnetic induction cycler (MIC) have been used to monitor the BRCA2 status highlighted by next generation tumor sequencing (NGTS): a combined approach in a diagnostic environment.

Resistance can be the result of secondary tissue variants (STVs), which restore the open reading frame of the germline BRCA allele, producing functional BRCA protein in germline BRCA1/2 (BRCA) pathogenic variant (PV) carriers, treated with platinum-based chemotherapy or poly-(ADP-ribose) polymerase inhibitors (PARP-1). We reported recently a BRCA2 mutant high grade serous ovarian cancer (HGSOC) patient with acquired resistance to the PARP-1 olaparib due to a STV detected by next generation tumor sequencing (NGTS). The aim of this study was to evaluate the versatility of the high-resolution melting analysis (HRMA) obtained by magnetic induction cycler (MIC) to monitor the BRCA2 status in formalin-fixed paraffin-embedded (FFPE) tissue samples of this patient and to compare the results obtained by NGTS.

PsA-Disk, a novel visual instrument to evaluate psoriatic arthritis in psoriatic patients: an Italian derma-rheuma multicentre study.

Background: Consensus among dermatologists and rheumatologists in the diagnosis and assessment of musculoskeletal diseases in psoriasis (PsO) patients is needed. This study assesses characteristics of musculoskeletal pain in patients with PsO for the presence of psoriatic arthritis (PsA) and evaluation of a novel 16-item visual instrument (PsA-Disk).

Methods: Data were collected from eight dermatological/rheumatological centres across Italy.

My Migraine Voice survey: a global study of disease burden among individuals with migraine for whom preventive treatments have failed.

Background: Migraine is associated with many debilitating symptoms that affect daily functioning. My Migraine Voice is a large global cross-sectional study aimed at understanding the full burden and impact of migraine directly from patients suffering from ≥4 monthly migraine days (MMDs) with a history of prophylactic treatment failure.

Methods: This study was conducted worldwide (31 countries across North and South Americas, Europe, the Middle East and Northern Africa, and the Asia-Pacific region) using an online survey administered to adults with migraine who reported ≥4 MMDs in the 3 months preceding survey administration, with pre-specified criteria of 90% having used preventive migraine treatment (80% with history of ≥1 treatment failure).

Prevalence and clinical characteristics of chronic spontaneous urticaria in pediatric patients.

Background: Data on the prevalence and disease management of chronic urticaria (CU) and chronic spontaneous urticaria (CSU) in the pediatric population are scarce. This study assessed the prevalence of CU and CSU, and disease management among pediatric patients (0-17 years).

Methods: A physician-based online survey was conducted in 5 European countries (United Kingdom, Germany, Italy, France, and Spain) assessing the annual diagnosed prevalence, disease characteristics, and treatment patterns in the target population.

In Situ and In Vitro Effects of Two Bleaching Treatments on Human Enamel Hardness.

The aim of this study was to evaluate in vitro and in situ the effects of two bleaching treatments on human enamel surface microhardness. Sixty enamel slabs from recently extracted thirty molars were used. The specimens were polished with sandpapers under water-cooling.

Light control of stoichiometry and motion in pseudorotaxanes comprising a cucurbit[7]uril wheel and an azobenzene-bipyridinium axle.

Pseudorotaxanes are the simplest prototypes for the construction of molecular machines based on threaded species. Investigation on molecular motions in these model systems is a necessary action for an efficient design of working molecular machines and motors. Herein we report on photoactive pseudorotaxanes based on the interaction between bipyridinium and cucurbit[7]uril (CB7).

Serum levels of functional T-regs in vitiligo: our experience and mini-review of the literature.

Vitiligo is an acquired depigmentary skin disorder due to the loss of cutaneous melanocytes or alteration in melanocyte function, affecting over 0.5% of the world population. The exact cause of melanocyte loss in non-segmental vitiligo is still debatable, but many observations have pointed to the main role of cellular immunity.

CD4+ CD25+ T-regulatory cells in psoriasis. Correlation between their numbers and biologics-induced clinical improvement.

Background: Regulatory T-cells (T-reg) play a central role in the immunopathogenesis of psoriasis. T-reg cells are both functionally and numerically impaired in psoriasis and they are up-regulated by drug therapy.

Objective: To analyse the circulating CD4+CD25 bright FOXP3+ subset in 14 patients with vulgaris/arthropathic psoriasis treated with biological drugs and to investigate their relationship with the clinical response.

Treatment of erythrodermic psoriasis in HCV+ patient with adalimumab.

Erythrodermic psoriasis is a severe and disabling variant of psoriasis. The authors present the case of a 48-year-old man with psoriasis and hemophilia presented with a history of hepatitis C virus (HCV) infection treated with pegylated interferon alpha-2a and ribavirin therapy. At the end of antiviral therapy, skin manifestation progressively worsened, becoming erythrodermic, with lack of efficacy of steroid therapy.

Skin ulcers in a patient afflicted with microscopic polyangiitis.

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation and blood vessel walls necrosis. Usually the skin is one of the first organs involved, especially with damage of small to medium size vessels. The cutaneous patterns may help clinicians to diagnose these diseases at the beginning of their course, preventing complications due to internal organ involvement.

A case of infliximab-induced psoriasis.

Anti-tumor necrosis factor (anti-TNF-alpha) are a group of new drugs able to inhibit the action of this cytokine. Although systemic side effects have been well described, cutaneous adverse reactions have not yet been clearly elucidated. The authors report a case of a 29-year-old man affected by Crohn disease and ankylosing spondylitis who developed psoriatic lesions after IV infusion of infliximab 5 mg/Kg.

Efficacy of Bosentan in treatment of refractory sclerodermic bone prominences skin ulcers.

Scleroderma is an autoimmune disease characterized by skin and internal organs involvement. Cutaneous ulcerations is one of the most important complication. It may cause pain, disability and may lead to infections, scarring and amputation.

[Pyoderma gangrenosum: case series].

Pyoderma Gangrenosum (PG) is a rare ulcerative cutaneous condition with distinctive characteristics, and the aetiology is not clear yet. PG is commonly associated with inflammatory bowel disease (Ulcerative Colitis and Crohn's disease). The features of PG are not specific histopathologically and for this reason diagnosis is based on clinical feature.

The use of elastocompressive therapy in a patient with acroangiodermatitis of the lower limb.

 Acroangiodermatitis is a rare vasoproliferative disorder, usually affecting the lower limbs and is associated with congenital or acquired vascular conditions. There are two variants of acroangiodermatitis-Mali type (associated with venous hypertension) and Stewart-Bluefarb type, which is associated with arteriovenous malformation, or acquired iatrogenic arteriovenous fistula in patients with chronic renal failure. Acroangiodermatitis is clinically characterized by angiomatous papules and plaques, which mimics Kaposi's sarcoma.

PEL, Kaposi's sarcoma HHV8+ and idiopathic T-lymphocitopenia CD4+.

We described a case report of a 36-year-old woman with a 10-year-history of idiopathic CD4+ T-lymphocitopenia and Kaposi's sarcoma HHV8+ who developed recurrent pleural effusion. Laboratory and instrumental tests with morphologic, immunophenotypic and molecular analysis of pleural sediment suggest us the diagnosis of primary effusion lymphoma (PEL). The term primary effusion lymphoma defines an extranodal non-Hodgkin's lymphoma HHV8-related, usually classified as a B-cell lymphoma, that grows in liquid-phase within body cavities.

Different effect of desipramine on locomotor activity in quinpirole-treated rats after repeated restraint and chronic mild stress.

We have studied the effect of chronic treatment with the tricyclic antidepressant drug desipramine on locomotor activity in rats challenged with the administration of the D2-like dopamine agonist quinpirole, after prolonged exposure to two different stress regimens, repeated restraint stress and chronic mild stress (different stressors randomly presented). These stress schedules have been previously reported to influence in opposite ways the sensitivity to the locomotor response mediated by the stimulation of mesolimbic dopamine receptors. In particular, repeated restraint has been reported to induce an increased response to the locomotor effect of amphetamine, while chronic mild stress has been reported to induce a decreased locomotor response to quinpirole.

Exploratory behaviour and grooming after repeated restraint and chronic mild stress: effect of desipramine.

In a previous study, we have recently shown that chronic treatment with desipramine either reduced or potentiated the locomotor response to the dopamine D(2)-like receptor agonist quinpirole, a behavioural response mediated by the mesolimbic dopamine system, depending on whether the animals were subjected, respectively, to repeated restraint or to chronic mild stress (different stressors randomly presented). In this study, we examined the interaction between prolonged exposure to either repeated restraint stress or chronic mild stress with the chronic administration of the antidepressant desipramine on two spontaneous behaviours, in which an involvement of the mesolimbic dopamine system has been suggested: novelty-induced exploratory activity and grooming. Exploratory activity in the open field was reduced by chronic mild stress regardless of the drug treatment, while it was not influenced by restraint stress.
