Oxidative Stress and Immune System in Vitiligo and Thyroid Diseases.

Vitiligo is an acquired dermatological disease frequently associated with autoimmune thyroid disorders. Several theories have been proposed so far to unravel the complex vitiligo pathogenesis. Currently, the autocytotoxic and the autoimmune theories are the most accredited hypothesis, since they are sustained by several important clinical and experimental evidences. A growing body of evidences shows that autoimmunity and oxidative stress strictly interact to finally determine melanocyte loss. In this scenario, associated thyroid autoimmunity might play an active and important role in triggering and maintaining the depigmentation process of vitiligo

Adult Onset Vitiligo: Multivariate Analysis Suggests the Need for a Thyroid Screening.

Background. There are limited epidemiological studies evaluating the effect of age at onset on disease features in vitiligo. Objectives. To identify factors associated with adult onset vitiligo in comparison with childhood onset vitiligo. Patients and Methods. We retrospectively collected medical records of 191 patients. Such records included clinical examination, personal and familial medical history, laboratory evaluations, concomitant vitiligo treatment and drug assumption. Results. 123 patients with a disease onset after the age of 40 (adult onset vitiligo) were compared with 68 patients who developed vitiligo before the age of 12 (childhood onset vitiligo). Multivariate analysis revealed that personal history of thyroid diseases (P=0.04; OR 0.4), stress at onset (P=0.002; OR = 0.34), personal history of autoimmune thyroid disease (ATD) (P=0.003; OR = 0.23), and thyroid nodules (P=0.001; OR 0.90) were independently associated with adult onset vitiligo, whereas family history of dermatological diseases (P=0.003; OR = 2.87) and Koebner phenomenon (P<0.001; OR = 4.73) with childhood onset vitiligo. Moreover, in the adult onset group, concomitant thyroid disease preceded vitiligo in a statistically significant number of patients (P=0.014). Conclusions. Childhood onset and adult onset vitiligo have different clinical features. In particular, ATD and thyroid nodules were significantly associated with adult onset vitiligo, suggesting that a thyroid screening should be recommended in this group of patients

Potential Infectious Etiology of Behçet's Disease

Behçet's disease is a multisystem inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. The cause of Behçet's disease remains unknown, but epidemiologic findings suggest that an autoimmune process is triggered by an environmental agent in a genetically predisposed individual. An infectious agent could operate through molecular mimicry, and subsequently the disease could be perpetuated by an abnormal immune response to an autoantigen in the absence of ongoing infection. Potentia bacterial are Saccharomyces cerevisiae, mycobacteria, Borrelia burgdorferi, Helicobacter pylori, Escherichia coli, Staphylococcus aureus, and Mycoplasma fermentans, but the most commonly investigated microorganism is Streptococcus sanguinis. The relationship between streptococcal infections and Behçet's disease is suggested by clinical observations that an unhygienic oral condition is frequently noted in the oral cavity of Behçet's disease patients. Several viral agents, including herpes simplex virus-1, hepatitis C virus, parvovirus B19, cytomegalovirus, Epstein-Barr virus and varicella zoster virus, may also have some role

Reorganization of Active Surveillance of Acute Flaccid Paralysis (AFP) in Emilia-Romagna, Italy: a two-step Public Health intervention

Background and aim of the work: The International Health Regulations Emergency Committee declared in 2014 that poliovirus circulation is a public health emergency of international concern. In 2017 and 2018 Italy was classified at intermediate risk of poliovirus reintroduction based on suboptimal poliovirus surveillance. Acute flaccid paralysis active surveillance is the gold standard in the polio eradication process. The aims of this study were to investigate the causes of reduced acute flaccid paralysis case reporting in Emilia-Romagna in the last few years (step 1) and to study a public health intervention to restore an adequate level of acute flaccid paralysis surveillance in that region (step 2). Methods: In the first step a context analysis was performed by analysing the 2015-2017 Hospital Discharge Registers in Emilia-Romagna with the ICD-9-CM differential diagnosis codes for acute flaccid paralysis. Data from context analysis was then used to plan a new regional collaborative network of acute flaccid paralysis active surveillance. Results: The active surveillance network was, at the end of the study, composed by 49 doctors from both hospital administrations and clinical wards from 4 University Hospitals and 7 Local Health Authorities throughout the Region. In 15 months, 7 acute flaccid paralysis cases have been reported; 85,7% received a full clinical and virological investigation and 83,3% completed the 60 day's follow-up. The mean response to each e-mail was 48,5% (SD 7,5%). Conclusions: In 2019, the Emilia-Romagna's active surveillance system reached the sensitivity, completeness of case investigation and follow-up required to achieve the minimum levels for certification standard surveillance

'We are all working toward one goal. We want people to become well': A visual exploration of what promotes successful collaboration between community mental health workers and healers in Ghana.

The practices of traditional and faith-based healers in low- and middle-income countries in Africa and elsewhere have come under intense scrutiny in recent years owing to allegations of human rights abuses. To mitigate these, there have been calls to develop collaborations between healers and formal health services to optimise available mental health interventions in poorly resourced contexts. For various reasons, attempts to establish such partnerships in a sustainable manner in different countries have not always been successful. In this article, we present findings from the Together for Mental Health visual research project to showcase examples of healer-health worker collaborations in Ghana that have been largely successful and discuss the barriers and facilitators to establishing these partnerships. Data reported in this article were collected using visual ethnography and filmed individual interviews with eight community mental health workers, six traditional and faith-based healers and two local philanthropists in the Bono East Region. The findings suggest that successful collaborations were built through mutually respectful interpersonal relationships, support from the health system and access to community resources. Although these facilitated collaboration, resource constraints, distrust and ethical dilemmas had to be overcome to build stronger partnerships. These findings highlight the importance of dedicated institutional and logistic support for ensuring the successful integration of the different health systems in pluralistic settings
