Influence of a Sulphur Dioxide Active Storage System on the Quality of Ribes rubrum L. Berries

The aim of this study was to evaluate the post-harvest changes in the quality of red currants ( Ribes rubrum L.) cv. ‘Rovada’ after 60 days of storage under modified atmosphere packaging (MAP) conditions. The storage unit was a pallet, and two treatments were performed. The CO 2 -MAP treatment was used as a control, while the SO 2 -MAP treatment was CO 2 -MAP plus SO 2 . The initial gas composition was 15.0 kPa O 2 and 10.0 kPa CO 2 inside all MAPs, while SO 2 -generating active sheets were added to pellets in SO 2 -MAP treatment. Weight loss, total soluble solid content, titratable acidity, total phenolic and anthocyanin contents, antioxidant activity, microbial count, and visual and sensorial appearance were monitored after 30 and 60 days. The results showed that berries stored with SO 2 maintained the quality parameters for up to 60 days. Exposure to SO 2 was effective in controlling yeast evolution, reducing the population both at 30 and 60 days at one and two orders of magnitude, respectively. Red currants stored under SO 2 MAP obtained better visual quality score compared to CO 2 MAP-treated berries throughout storage. Active emitters of SO 2 , such as those proposed in this study, can be promising solutions to improve the post-harvest storage of red currants and the berries marketability

Polymyositis following Pandemic Influenza A (H1N1) and 2009-10 Seasonal Trivalent Vaccines

Sporadic associations between inflammatory myopathies with vaccinations were described in the literature, raising the possible trigger value of vaccines in the development of these autoimmune disorders. Here, we reported the clinical history of 3 patients who developed polymyositis complicated by interstitial lung disease (2 cases) and dermatomyositis (1 case), after influenza A (H1N1) vaccination

Current treatment of hepatitis C-associated rheumatic diseases.

ABSTRACT: The hepatitis C virus (HCV) is both hepatotropic and lymphotropic, responsible for a great number of hepatic and extrahepatic immune-system disorders that comprise the so-called HCV syndrome. HCV-associated rheumatic diseases are characterized by frequent clinico-serological overlap; therefore, correct classification of individual patients is necessary before therapeutic decisions are made. This is particularly difficult to do, however, because of the coexistence of viral infection and complex autoimmune alterations. In this context, mixed cryoglobulinemia syndrome (MCs) represents the prototype of virus-related autoimmune-lymphoproliferative diseases. MCs can be treated at different levels by means of etiological treatment with antivirals (peg-interferon-alpha plus ribavirin) aimed at HCV eradication and/or pathogenetic/symptomatic treatments directed to both immune-system alterations and the vasculitic process (rituximab, cyclophosphamide, steroids, plasmapheresis, and so on). In clinical practice, the therapeutic strategy should be modulated according to severity/activity of the MCs and possibly tailored to each individual patient's conditions. Cryoglobulinemic skin ulcers may represent a therapeutic challenge, which should be managed by means of both local and systemic treatments. HCV-associated arthritis should be differentiated from the simple comorbidity of HCV infection and classical rheumatoid arthritis. It may be treated with low doses of steroids and/or hydroxychloroquine; the use of biologics (rituximab) may be considered in more severe cases. Primary Sj\uf6gren's syndrome is rarely associated with HCV infection, while sicca syndrome and myalgia are frequently detectable in hepatitis C patients, with or without cryoglobulinemic vasculitis. Other autoimmune rheumatic disorders (poly/dermatomyositis, polyarteritis nodosa, osteosclerosis, fibromyalgia, and so on) have been reported as potentially associated with HCV infection in patient populations from different countries, suggesting the role of genetic and/or environmental co-factors. The therapeutic approach to these disorders should be decided according to each individual patient's evaluation, including hepatic, virological, and immunological findings

HHV-6A infection and systemic sclerosis: Clues of a possible association

Systemic sclerosis (SSc) is an autoimmune disease characterized by vasculopathy, excessive extracellular matrix deposition, and fibrosis of the skin and internal organs. Several infectious agents, including human herpesvirus-6 (HHV-6), have been suggested as possible triggering factors, but a direct association is still missing. We characterized 26 SSc patients for the presence of HHV-6 in tissues and blood, the anti-HHV-6 response, HLA-G plasma levels, and KIR typing. Given the prominent role of endothelial cells (EC) in SSc pathogenesis, along with HHV-6 tropism for EC, we also investigated the expression of pro-fibrosis factors in HHV-6 infected EC. Results showed the presence of HHV-6A in skin biopsies, and an increased virus load was associated with disease severity and poor natural killer (NK) response against the virus, particularly in subjects exhibiting a KIR2 phenotype. HLA-G plasma levels were significantly higher in HHV- 6A/B-KIR2 positive SSc patients and in vitro HHV-6A infection-induced pro-fibrosis factors expression in EC, supporting its role in the development of the fibrosing process. Our data suggest an association between virus infection/reactivation and disease, opening the way to future studies to understand the mechanisms by which HHV-6A might contribute to the multifactorial pathogenesis of SSc

Carotidynia Possibly due to Localized Vasculitis in a Patient with Latent Mycobacterium tuberculosis Infection.

Carotidynia is a syndrome characterized by tenderness of the carotid artery near the bifurcation due to numerous, heterogeneous causes. Here we reported the case of a 31-year-old Moroccan woman with right-sided neck pain and tenderness with irradiation to ipsilateral ear, eye, and occipital region. Clinical symptoms and imaging findings were suggestive of primary variant of carotidynia syndrome. In particular, color-Doppler ultrasonography revealed a concentric wall thickening of the distal common carotid artery, while thoracic magnetic resonance showed localized perivascular enhancement of the soft tissue in the right medial-distal common carotid artery in T1-weighted images, without intraluminal diameter variation. Moreover, careful clinicoserological and imaging investigations (cranial, cervical, and thoracic angiocomputed tomography and magnetic resonance) excluded well-known disorders potentially responsible for carotidynia syndrome. The patient was scarcely responsive to nonsteroidal anti-inflammatory drugs, but clinical symptoms resolved after three months. Of interest, the patient showed latent Mycobacterium tuberculosis infection (positive tuberculosis interferon-gamma release assay; QuantiFERON-TB Gold); this finding suggested a possible triggering role of mycobacterial antigens in the immune-mediated mechanism responsible for localized carotid injury

Selection and micropropagation of valuable caper genotypes

The high quality of the various biotypes present in the natural or cultivated state is one of the main features for caper production. Up to now, however, no selection activity has been carried out in order to identify the most suitable accessions for providing better quality products. In this paper, we report the first results of a selection of caper genotypes characterised by significant qualitative traits. A micropropagation protocol was evaluated in order to improve and allow the multiplication of the most promising Capparis spinosa L. subsp. spinosa genotypes, selected in Salina (Aeolian Islands), Sicily (Italy), in collaboration with the most important local growers

Incidence of thyroid disorders in systemic sclerosis: results from a longitudinal follow-up

Context: Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology, and several studies reported its association with thyroid autoimmune disorders. No study has evaluated longitudinally the incidence of new cases of thyroid autoimmunity and dysfunction in patients with SSc. Objective: The purpose of this study was to evaluate the incidence of new cases of clinical and subclinical thyroid dysfunction in a wide group of women with SSc vs an age- and sex-matched control group from the same geographic area. Design and Patients or Other Participants: After exclusion of sclerodermic patients with thyroid dysfunction (n = 55) at the initial evaluation, the appearance of new cases of thyroid disorders was evaluated in 179 patients and 179 matched control subjects, with similar iodine intake (median follow-up 73 months in patients with SSc vs 94 months in control subjects). Results: A high incidence (P < .05) of new cases of hypothyroidism, thyroid dysfunction, anti-thyroperoxidase antibody positivity, and appearance of a hypoechoic thyroid pattern in sclerodermic patients (15.5, 21, 11, and 14.6 of 1000 patients per year; respectively) vs that in control subjects was shown. A logistic regression analysis showed that in patients with SSc, the appearance of hypothyroidism was related to a borderline high initial TSH level, anti-thyroperoxidase antibody positivity, and a hypoechoic and small thyroid. Conclusions: Our study shows a high incidence of new cases of hypothyroidism and thyroid dysfunction in female sclerodermic patients. Female sclerodermic patients, who are at high risk (a borderline high [even if in the normal range] TSH value, anti-thyroperoxidase antibody positivity, and a hypoechoic and small thyroid) should have periodic thyroid function follow-up

PAP-TEST FEATURES IN A COHORT OF SYSTEMIC SCLEROSIS PATIENTS

Background: Increased incidence of malignancies was frequently reported in systemic sclerosis (SSc), as well as for other autoimmune diseases. Besides the previously observed association with lung cancer1 and the increased risk for breast cancer2, no association with cancer of the cervix has been described in literature. However, cervical uterus malignancy is one of the most frequent cancer in women so that public health programs of screening have been established in several countries worldwide. In Italy, the pap cytology test is recommended every 3 years for all women between 25 and 64 years old. Objectives: To investigate pap-test features in SSc patients. Methods: We retrospectively evaluated a cohort of 80 consecutive female SSc patients (mean age 51.2±12SD years, disease duration 7.9±5.8SD years, limited/diffuse skin subsets 72/8), who underwent to pap cytology tests as screening for cancer of the cervix, during the period between January 1st, 2008 and December 31th, 2014. All patients came from the same geographical area (province of Modena, Northern Italy). Clinical, serological, and instrumental data of SSc patients were collected and related to cytological findings. Results: At gynaecological and pap test evaluations, 55 (68.7%) patients were negative, while 20 (25%) presented inflammatory alterations (i.e. chronic cervicitis); while atypical cells related to cancer or pre-cancerous lesions were found in 5 (6.2%) cases. Namely, 2 women showed cervix cancer (one of them in situ), 1 a vulvar melanoma, 1 a vulvar intraepithelial neoplasia, and 1 an endocervical polyp with immature squamous metaplasia at histology. The frequency of cervix cancer in our series seems to be clearly higher in comparison to the incidence registered in the same geographical area and in the same years (standardized rate 8, 95%IC 5.2-10.7 cases out of 100,000 subjects). At statistical analysis, the atypical cytological findings correlated with serum anti-Scl70 autoantibodies (4/5 vs. 19/75; p=0.022); moreover, the patients with these alterations tended to be older (median 65, range 46-67), if compared to the whole series (p=0.052). No statistical correlations with skin or visceral involvements, smoking history, treatment with immunosuppressors were found. Conclusions: In our SSc patients' series, we found a relatively high frequency of cancerous lesions of the cervix by means of pap test. A significant correlation with anti-Scl70 autoantibodies was also found. These preliminary findings need to be verified in larger controlled epidemiological studies
