The pipeline project:Pre-publication independent replications of a single laboratory's research pipeline

This crowdsourced project introduces a collaborative approach to improving the reproducibility of scientific research, in which findings are replicated in qualified independent laboratories before (rather than after) they are published. Our goal is to establish a non-adversarial replication process with highly informative final results. To illustrate the Pre-Publication Independent Replication (PPIR) approach, 25 research groups conducted replications of all ten moral judgment effects which the last author and his collaborators had "in the pipeline" as of August 2014. Six findings replicated according to all replication criteria, one finding replicated but with a significantly smaller effect size than the original, one finding replicated consistently in the original culture but not outside of it, and two findings failed to find support. In total, 40% of the original findings failed at least one major replication criterion. Potential ways to implement and incentivize pre-publication independent replication on a large scale are discussed. (C) 2015 The Authors. Published by Elsevier Inc.</p

Data from a pre-publication independent replication initiative examining ten moral judgement effects

We present the data from a crowdsourced project seeking to replicate findings in independent laboratories before (rather than after) they are published. In this Pre-Publication Independent Replication (PPIR) initiative, 25 research groups attempted to replicate 10 moral judgment effects from a single laboratory's research pipeline of unpublished findings. The 10 effects were investigated using online/lab surveys containing psychological manipulations (vignettes) followed by questionnaires. Results revealed a mix of reliable, unreliable, and culturally moderated findings. Unlike any previous replication project, this dataset includes the data from not only the replications but also from the original studies, creating a unique corpus that researchers can use to better understand reproducibility and irreproducibility in science

A review of vitamin B12 in dermatology

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is important in the hematological and nervous systems, and it has a complex relationship with the skin. Altered cobalamin levels can lead to dermatological manifestations, which may indicate a deficiency or excess of this vitamin. The biochemistry and metabolism of cobalamin is complex, and diseases can be associated with alterations of this metabolic pathway. The cutaneous manifestations of cobalamin deficiency include hyperpigmentation (most commonly); hair and nail changes; and oral changes, including glossitis. Additionally, several dermatologic conditions, including vitiligo, aphthous stomatitis, atopic dermatitis, and acne are related to cobalamin excess or deficiency. The cutaneous complications of cobalamin therapy include acne, rosacea, and allergic site reactions, or anaphylaxis with cobalamin injections. As cobalt is a component of cobalamin, patients with cobalt sensitivity have been reported to have cutaneous manifestations when receiving cobalamin replacement therapy

Pseudoverrucous papules and nodules in the setting of a chronically draining abscess

We report a case of a 48-year-old African American male with a history of poorly controlled diabetes and hypertension was admitted to the hospital for a chronically draining left mid back paraspinal abscess for over one year. He had a history of recurrent abscesses on different areas of his skin, however the one on his left back had been persistent. On physical exam, on the mid back to the left of midline there was a collection of verrucous, keloidal papules and nodules coalescent into a large irregularly shaped plaque with surrounding erythema, tenderness and fluctuance. Punch biopsies of the exophytic nodules showed acanthosis, hyperkeratosis, papillomatosis, fibrotic dermis with increased vessels, and sparse lymphoid inflammation. These histologic findings were consistent with the diagnosis of pseudoverrucous papules and nodules (PPN). After failing multiple oral antibiotics, per the Infectious Disease team the patient was treated with IV daptomycin and the goal was to keep the skin clean and dry. PPN has been commonly described in the perianal or peristomal region in children or adults with chronic urinary and/or fecal incontinence for multiple reasons. It was first noted around urostomy sites. In all cases of PPN, prolonged wetness seems to be the key factor. It has been proposed that Jacquet erosive diaper dermatitis and granuloma gluteal infantum/adultorum are a spectrum of disease with PPN. The most important factor in treating PPN is removing the irritant. Zinc oxide creams can restore the barrier function of the skin and topical steroids decrease inflammation

Phototherapy-related ophthalmologic disorders

Phototherapy is an effective treatment option for a variety of dermatologic disorders, and the list of indications for its use continues to grow with advances in technology and our understanding of disease processes. Commonly used types of phototherapy include PUVA, broadband UVB, narrowband UVB, photodynamic therapy, and intense pulsed light therapy. Each therapeutic modality can have adverse acute and chronic effects on periocular and ocular structures, including the conjunctiva, cornea, crystalline lens, and retina. There are many types of protective eyewear options available, including goggles and contact lenses that can be used to prevent damage to ocular structures during phototherapy, particularly if eyelid closure is incomplete

Photosensitive disorders of the skin with ocular involvement

Patients with photosensitive disorders of the skin may present with ocular manifestations that are evident at birth or may be manifested later with progression of the disorder. Dermatologists should be able to recognize these and appropriately refer patients for further management. Ocular involvement associated with immunologically mediated photodermatoses, drug- and chemical-induced photosensitivity, photodermatoses associated with defective DNA repair/chromosome instability, and photoaggravated dermatoses are reviewed. Photodermatoses are commonly classified into four general groups: (1) immunologically mediated photodermatoses; (2) drug- and chemical-induced photosensitivity; (3) photodermatoses associated with defective DNA repair/chromosome instability; and (4) photoaggravated dermatoses. Photodermatoses in these groups with ocular involvement will be discussed. In addition, skin diseases associated with photophobia are also described
