The association between psychiatric and dermatologic disorders has been well characterized in the present literature with estimates of up to 40% of dermatology patients having concomitant psychiatric problems that are often related to their skin condition. Here, we present our experience regarding the implementation of a psychodermatology clinic in Detroit, Michigan. The most commonly referred conditions were delusions of parasitosis, neurotic excoriations, and isotretinoin initiation for patients with a history of psychiatric conditions. Seventy-three percent of referred patients were female. By creating a monthly clinic for patients who are diagnosed with skin conditions and associated psychiatric disorders or psychological symptoms, we are able to meet the needs of these patients with a synergistic relationship between health care providers.

Lymphoplasmacytic plaque in children has been proposed as a rare, emerging clinicopathologic entity characterized by solitary, extratruncal, asymptomatic papules and plaques that are typically found in healthy young Caucasian females. Biopsy of these lesions reveals a dermal lymphoplasmacytic infiltrate with or without epithelioid granulomas. Two unique patients with lymphoplasmacytic plaque in children are presented in this report, including a 26-month-old female with a lesion on her finger, who represents both the youngest described patient and the first documented with a finger lesion, as well as a 17-year-old young woman with a left thigh lesion, who represents the patient with the longest clinically and histopathologically observed lesion to date. These two additional patients corroborate the experience of lymphoplasmacytic plaque in children in the six previously reported cases and further expand the clinicopathologic spectrum of the disease. Recognition of lymphoplasmacytic plaque in children is important to facilitate distinction from potential differential considerations, including lymphoproliferative disorders and infectious conditions, particularly as the experience to date appears to suggest that lymphoplasmacytic plaque in children represent a reactive (pseudolymphomatous) condition.

To review blockchain lessons learned in 2018 and near-future predictions for blockchain in healthcare, Blockchain in Healthcare Today (BHTY) asked the world's blockchain in healthcare experts to share their insights. Here, our internationally-renowned BHTY peer-review board discusses their major predictions.Based on their responses, presented in detail below, ten major themes (Table ) for the future of blockchain in healthcare will emerge over the 12 months.

Herpes zoster (shingles) is the result of a reactivation of the varicella zoster virus (VZV). Many adults obtain a VZV vaccine in order to prevent zoster. Non-specific injection site reactions and generalized herpes eruptions have been reported to occur, especially in immunocompromised patients. However, these are most often anatomically generalized reactions and histopathologically resemble typical herpes infections. We report a 61-year-old female on immunosuppressant medications for rheumatoid arthritis who presented with a subcutaneous nodule at the site of a recent herpes zoster vaccination. Histopathological examination revealed a dense nodular and interstitial mononuclear infiltrate throughout the mid and deep dermis with extension into the superficial subcutaneous fat. Immunohistochemical staining revealed an admixture of T-cells and B-cells, with a predominance of T-cells. These findings are consistent with a pseudolymphoma (PL), a reactive inflammatory disorder that can resemble cutaneous lymphoma and has rarely been described in herpes infections and post-herpetic scars. In situ hybridization studies for VZV were performed and highlighted occasional deep fibroblasts with nuclear positivity for VZV DNA. A review of post-vaccination reactions and herpes-related PL is discussed with emphasis on using in situ hybridization in establishing the diagnosis.
