Filter by:The rationale for this study is to assess the change in ambulatory care visit rates for acute otitis media between the period before (2001-2009) and after the introduction of the 13-valent pneumococcal conjugate vaccine (13vPnC) (2011-2013) among children less than 5 years old in the United States.
Polymorphic light eruption (PLE) is a photodermatosis with an extremely high prevalence, particularly among young women (up to 20%). The disease is characterized through itchy skin lesions on sun-exposed body sites occurring after sun exposure mostly in spring and early summer. Its etiopathogenesis is unknown but resistance to ultraviolet radiation (UVR)-induced immunosuppression with subsequent immune reactions against skin photoneoantigens has been suggested. The phenomenon of UVR-induced immunosuppression (suppression of CHS) has been well known for many years. Recent findings showed that regulatory T cells (CD4+CD25+FoxP3+) (Tregs), a subset of T helper cells, are crucial in UVR-induced immunosuppression. However, the requirements for the maintenance of peripheral CD4+CD25+ T cells, important in suppression of immune responses, are still incompletely understood. Recent work suggests that cutaneous RANKL might be the physiologic missing link that couples UVR to immunosuppression. Epidermal RANKL, expressed in keratinocytes of inflamed skin due to e.g. UVR exposure was shown to control the number of Tregs via activation of dendritic cells, hereby mediating UVR-induced immunosuppression (e.g. suppression of allergic contact hypersensitivity responses). In addition to the suppression of local cutaneous hyperallergic responses, the development of systemic autoimmunity is suppressed. A strong inducer of RANKL expression and of Tregs is vitamin D3 that has been reported to have immunosuppressive effects. Interestingly, patients with autoimmune disorders (e.g. lupus erythematosus) may exhibit reduced vitamin D3 blood levels. This randomized, double blinded left-right body side experimental comparison study was designed to assess the preventive effect of the vitamin D3 analogue calcipotriol in patients with PLE. The hypothesis is tested that treatment with a calcipotriol-containing cream can prevent the UVR-induced development of PLE skin lesions. Better insight into the pathogenesis of PLE may give clues to develop new therapeutic strategies.
This is a clinical research study of an experimental new medication, Menadione Topical Lotion (MTL). The study lotion is experimental and has not been approved for public use. Hana Biosciences, Inc., the company that is developing MTL, is the sponsor of this study. EGFR inhibitors are used to treat non-small cell lung cancer (NSCLC), pancreatic cancer, colorectal cancer, breast cancer and head and neck cancer. One of the side effects of EFGR inhibitors is skin toxicities including an acneform skin rash. This study is a Phase 1 study. The main purposes of this study are: - Evaluate the safety and tolerability of Menadione Topical Lotion as an emergent and pre-emergent treatment for EGFR inhibitor-associated rash - Evaluate the systemic absorption and bioavailability of Menadione Topical Lotion as an emergent and pre-emergent treatment for EGFR inhibitor-associated rash It is planned that up to 24 patients undergoing EGFR inhibitor therapy will take part in this study at multiple clinical centers.

Its etiopathogenesis is unknown but resistance to UV-induced immunosuppression with subsequent immune reactions against skin photoneoantigens has been suggested. Regulatory T cells (CD4+CD25+FoxP3+) (Tregs), a subset of T helper cells, are crucial for the induction of immunosuppression. We will test the hypothesis that PLE patients show pathogenic fluctuating Treg levels and function and related parameters over the seasons of the year, possibly being responsible for lack of immune modulation and autoimmunity in PLE. Natural or medical photohardening may normalize Treg deficiency in PLE and lead to clinical adaption in summer. Better insight into the pathogenesis of PLE may give clues to develop new therapeutic strategies.
Polymorphic light eruption (PLE) is a common photodermatosis characterized by the appearance of itching, erythema, papules or vesicles on sun-exposed skin. Though etiology is unclear it is hypothesized that it is an abnormal immune response to autologous antigens generated by ultraviolet radiation (UVR). This randomized, double blinded left-right body side experimental comparison study was designed to assess the preventive effect of a sunscreen and topical DNA repair enzyme-containing after-sun lotion in PLE.
The purpose of this study is to determine whether the afamelanotide (CUV1647) formulation is effective in preventing PLE episodes or reducing the severity of PLE symptoms in patients with a well documented history of the disease. The study also aims to determine whether treatment with afamelanotide (CUV1647) can reduce the use of rescue medication in this group.
RATIONALE: Topical sunscreen may be effective in preventing skin rash caused by treatment with drugs such as erlotinib or cetuximab. It is not yet known whether topical sunscreen is more effective than a placebo in preventing skin rash in patients receiving drugs such as erlotinib or cetuximab for cancer. PURPOSE: This randomized phase III trial is studying topical sunscreen to see how well it works compared with a placebo in preventing skin rash in patients receiving drugs such as erlotinib or cetuximab for cancer.
A comparison of prophylactic treatment with reactive treatment for skin toxicity observed in patients with metastatic colorectal cancer (mCRC) who are receiving second-line irinotecan-based chemotherapy concomitantly with panitumumab.
RATIONALE: Tetracycline may be effective in preventing skin rash that is caused by treatment with drugs such as gefitinib or cetuximab. PURPOSE: This randomized clinical trial is studying tetracycline to see how well it works compared to placebo in preventing skin rash in patients who are receiving drugs such as gefitinib or cetuximab for cancer.
