Primary biliary cholangitis (PBC) is an autoimmune liver disease with a striking female preponderance. The mechanisms behind this predominance are still to be elucidated, although multiple theories have been postulated and investigated. Among the proposed involved factors, sex hormones have been the first to be studied, but unfortunately data have been inconclusive or conflicting. Similarly, fetal microchimerism has received a huge attention in the past, but data in PBC have been unsatisfactory especially if compared to other autoimmune diseases like systemic lupus erythematosus...

INTRODUCTION: Peyronie's disease (PD) is a fibrotic disorder that leads to plaque formation in ∼3-9% of adult men. Connective tissue buildup results in plaque formation, penile curvature and shortening, and in some cases, pain. In the active phase of PD, penile pain is a common symptom, often accompanied by progression in curvature. Treatment options for PD include oral drugs, topical cream, intralesional injections, traction, and shock wave therapy. This article reviews the different treatment options for active-phase PD...

OBJECTIVE: Resolvins have been shown to attenuate inflammation, whereas NETosis, the process of neutrophils releasing neutrophil extracellular traps (NETs), produces increased inflammation. It is hypothesized that treatment of animals with resolvin D1 (RvD1) would reduce abdominal aortic aneurysm (AAA) formation by inhibiting NETosis. METHODS: Wild-type 8- to 12-week-old C57BL/6 male mice (n = 47) and apolipoprotein E-deficient (ApoE-/- ) mice (n = 20) were used in two models to demonstrate the effects of RvD1 on AAA growth...

Skin contains a large number of antigen presenting cells, making intradermal (ID) injection one of the most effective ways for vaccine administration. However, although current adjuvants may cause severe local reactions and inflammations in the skin, no adjuvant has been approved for ID vaccination so far. Here, we report that topical application of all- trans retinoic acid (ATRA), a vitamin A derivative produced in the human body, augmented cutaneous influenza vaccination. The adjuvant effects were evaluated in a murine vaccination/challenge model by using A/California/07/2009 pandemic vaccine (09V) or a seasonal influenza vaccine (SIV)...

A series of paediatric patients is presented in whom topical interferon alpha-2b was used as a co-adjuvant treatment for conjunctival papilloma. This condition is frequently associated with human papillomavirus infection. There is little information on the pediatric population with the use of interferon for the treatment of these lesions. In this case series, adjuvant treatment with topical interferon alpha-2b in paediatric patients showed no recurrence and good tolerance.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by complex symptoms. To treat AD without adverse effects, alternative therapeutic agents are required. The tubers of Helianthus tuberosus L. (Jerusalem artichoke) have been used in folk remedies for diabetes and rheumatism. However, its effect on AD development remains unknown. Therefore, this study examined the inhibitory effect of H. tuberosus (HT) on AD skin symptoms using an NC/Nga mouse model and HaCaT keratinocytes. The effect of HT and associated molecular mechanisms were evaluated in Dermatophagoides farina body (Dfb)-induced AD mice and tumor necrosis factor (TNF)-α/interferon (IFN)-γ-stimulated HaCaT keratinocytes by ELISA, western blot, and histological analysis...

OBJECTIVE: The use of beneficial bacteria may stimulate wound healing. We performed a randomized, placebo-controlled double-blind cross-over study comprising ten healthy volunteers. The aim was to investigate the impact of topical and systemic applications of probiotic lactobacilli (Lactobacillus reuteri) on the healing of standardized wounds (punch biopsies) in the oral mucosa. The expression of selected matrix metalloproteinases (MMP'S) and interferons (IFN's) was analyzed with multiplex immunoassays in the wound exudate during the first healing week (day 2, 5 and 8)...

Enterovirus (EV) infections are a major threat to global public health, and are responsible for mild respiratory illness, hand, foot, and mouth disease (HFMD), acute hemorrhagic conjunctivitis, aseptic meningitis, myocarditis, severe neonatal sepsis-like disease, and acute flaccid paralysis epidemic. Among them, HFMD is a common pediatric infectious disease caused by EVs of the family Picornaviridae including EV-A71, coxsackieviruses (CV)-A2, CV-A6, CV-A10, and CV-A16. Due to lack of vaccines and specific antiviral therapeutics, millions of children still suffer from HFMD...

PURPOSE: To determine the mucinogenic effect of dry eye (DE) treatment drugs currently in use, we compared the levels of mucin production and inflammatory cytokine expression on the ocular surfaces using a DE-induced mice model. METHODS: C57BL/6 mice were separated into 6 groups: a control group, DE-induced mice with the vehicle and treated with cyclosporine A (CsA), rebamipide (Reb), diquafosol tetrasodium (DQS), or prednisolone (Pred). The mRNA expression of MUC 1, 4, 16, 5AC, and proinflammatory cytokines on the corneal epithelia were determined by quantitative real-time polymerase chain reaction...

INTRODUCTION: Direct-acting antivirals are new drugs for chronic hepatitis C treatment. They are usually safe and well tolerated, but can sometimes cause serious adverse effects and there is no consensus on how to treat or prevent them. We described a case of hand-foot syndrome due to hepatitis C virus interferon-free therapy. METHODS: We report the case of a 49-year-old man with compensated liver cirrhosis due to chronic hepatitis C genotype 1, treatment-naïve, who started viral treatment with sofosbuvir, simeprevir and ribavirin for 12 weeks...
