Facial Allergic Granulomatous Reaction and Systemic Hypersensitivity Associated With Microneedle Therapy for Skin Rejuvenation

IMPORTANCE Microneedle therapy includes skin puncture with multiple micro-sized needles to promote skin rejuvenation or increase transdermal delivery of topical medications. In cosmetic practices, various cosmeceuticals are applied before microneedling to enhance the therapeutic effects. This results in intradermal tattooing of the topical product. Despite rapid increase in the use of microneedles in dermatology, there are few data about their safety. OBSERVATIONS We describe 3 women, aged 40s to 60s, who developed open [corrected] facial granulomas following microneedle therapy for skin rejuvenation. Two patients had undergone microinjection of the same branded topical moisturizer (Vita C Serum; Sanítas Skincare) during microneedle therapy. Biopsy in all cases showed foreign body-type granulomas. Results of tissue cultures were negative. Chest radiography and serum angiotensin-converting enzyme findings were normal. The first 2 patients had a positive patch test reaction to Vita C Serum. Initial treatment with topical and oral corticosteroids was ineffective. Therapy with doxycycline hydrochloride and minocycline hydrochloride led to partial improvement in one case and resolution in another. CONCLUSIONS AND RELEVANCE Application of topical products prior to microneedling can introduce immunogenic particles into the dermis and potentiate local or systemic hypersensitivity reactions. Because the microneedle therapy system is accessible for home use, health care providers need to be aware of its potential consequences.

Quality-of-Life Instruments: Evaluation of the Impact of Psoriasis on Patients

The negative impact of psoriasis on a patients quality of life (QoL) is well documented in the literature. Patients often suffer poor self-esteem, difficulties in social interactions, and significant psychological distress. It is, therefore, critically important that a clinician evaluate the extent to which the disease impacts a patients QoL. This chapter reviews several validated and reliable generic, dermatology-specific, and disease-specific QoL instruments useful in measuring the impact of psoriasis on patients QoL. These QoL instruments can be especially helpful in identifying those patients who would most benefit from systemic or biologic therapy.

Access to Health Care in Patients With Psoriasis and Psoriatic Arthritis Data From National Psoriasis Foundation Survey Panels

IMPORTANCE This article represents a real-world perspective on access to health care including the number and types of physicians seen by patients with psoriasis. It is important for practicing dermatologists to recognize patients who may be less likely to seek care for this multifaceted systemic disease as well as to be aware of reasons for not seeing physicians. OBJECTIVES To examine the relationship between psoriasis patient characteristics and access to health care and to determine out-of-pocket costs for psoriasis care. DESIGN Cross-sectional survey. SETTING Patients with psoriasis and psoriatic arthritis in the general community in the United States. PARTICIPANTS A random sample of patients with psoriasis and psoriatic arthritis from more than 75,000 National Psoriasis Foundation members. MAIN OUTCOMES AND MEASURES Number and type of physicians seen in the past 2 years and out-of-pocket health care expenses were measured. RESULTS Among 5604 patients with psoriasis and psoriatic arthritis, 92.4% had seen at least 1 physician in 2 years. Compared with males, female patients with psoriasis were 1.47 times more likely to seek care (adjusted odds ratio, 1.47; 95% CI, 1.18-1.83). Patients with private insurance and Medicare were more likely to seek care compared with uninsured patients (adjusted odds ratio, 3.02; 95% CI, 2.23-4.08 and 2.85; 1.91-4.24, respectively). Among patients with psoriasis seeking care, 78.3% were seeing specialists; 22% obtained care from primary care physicians. Primary reasons for not seeking treatments included giving up on disease treatment (27.6%) and prohibitive cost (21%). Compared with patients with mild disease, patients with severe psoriasis were more likely to seek a specialist for care (adjusted odds ratio, 1.64; 95% CI, 1.37-1.98). Patients spent an average of

2528 out-of-pocket per year for psoriasis care. CONCLUSIONS AND RELEVANCE About one-quarter of patients seek psoriasis care from primary care physicians, and insurance status affects care-seeking patterns. Giving up on treatment and prohibitive costs remain primary reasons for not seeking care.

Delusional infestations: clinical presentation, diagnosis and treatment

Issues related to prescribing dermatologic drugs in the elderly are less recognized than age-related skin findings. This is related in part to the lack of a standardized residency training curriculum in geriatric dermatology. As the number of elderly patients rises in the United States, drug-related iatrogenic complications will become increasingly important. This review discusses age-related changes in pharmacokinetics and pharmacodynamics of common dermatologic drugs. These changes include volume of distribution, renal function, liver toxicity from interactions of commonly prescribed drugs, and medications that can decompensate cognition in the older patient population. We outline seven prescribing principles related to older dermatology patients, including useful strategies to reduce polypharmacy and improve drug adherence, using an evidence-based approach whenever possible.

Primary psychiatric conditions: Dermatitis artefacta, trichotillomania and neurotic excoriations

Patients with delusional infestations (DI), previously named delusions of parasitosis, have a fixed, false belief that they are infested with living or non‐living pathogens. Patients have abnormal cutaneous symptoms such as itching, biting, or crawling sensations. They often demonstrate self‐destructive behavior in an effort to rid the pathogens from under their skin, leading to excoriations, ulcerations, and serious secondary infections. This review article aims to provide an overview of DI including its clinical presentation, diagnosis, and treatment. Strategies on how to establish a strong therapeutic alliance with DI patients are discussed. In addition, antipsychotic medications used in the treatment of DI are described.

The Safety of Systemic Treatments That Can Be Used for Geriatric Psoriasis Patients: A Review

Primary psychiatric conditions encountered in dermatology include dermatitis artefacta, trichotillomania (TTM) and neurotic excoriations. For these disorders, the primary pathologic condition involves the psyche; therefore, any cutaneous findings are self-induced. Herein, we review common primary psychiatric conditions in dermatology – dermatitis artefacta, neurotic excoriations and TTM – and examine their epidemiology, clinical presentation, differential diagnosis and treatment strategies. For all primary psychiatric disorders, the most effective underlying strategy is to first establish a strong therapeutic rapport with the patient. Various pharmacologic and non-pharmacologic therapies can then be attempted afterwards to successfully manage these patients.

Delusions of parasitosis

Background. Patients with moderate-to-severe psoriasis are often treated with systemic immunosuppressant agents that decrease immune system function. For the elderly, these medications are often problematic due to their already immunosuppressed state and comorbidities. However, there are few studies examining the effects of these medications on the elderly age group. Therefore, there is often discomfort among dermatologists treating elderly patients with psoriasis in utilizing systemic agents, frequently resulting in inadequate treatment. Objective. We review the safety profiles of systemic treatments often used to treat psoriasis and their possible adverse risks to the geriatric population. Methods. We conducted a search of PubMeds Medline database of articles published from 2000 to 2011, which resulted in 14 articles. Conclusion. Treating geriatric patients with moderate-to-severe psoriasis remains a challenge due to immunosenescence and comorbidities. More studies focusing on psoriasis treatment safety in the geriatric population are needed.

Geriatric dermatology: Part II. Risk factors and cutaneous signs of elder mistreatment for the dermatologist.

Patients with delusions of parasitosis (DOP) are more commonly recognized in dermatology practices today. However, dermatologists may feel uncomfortable treating these patients because of the psychiatric nature of their disorder. As a result of the fact that DOP patients strongly prefer to seek treatment from dermatologists rather than mental health professionals, it is important for dermatologists to be well equipped with a basic understanding of the disorder and with tools to assist this patient population. In this review, we discuss the epidemiology, presentation, differential diagnosis and treatment strategy for patients with DOP.

Dermatogeriatrics: a case for developing a new dermatology subspecialty

Cutaneous signs may be the most visible hint of elder mistreatment. Dermatologists are in a unique position to recognize and report physical abuse and neglect in the older patient population. In this review, we describe the scope and impact, risk factors, cutaneous signs, and appropriate responses to suspected elder mistreatment. There is a critical need for additional evidence to inform clinical practice in the field of elder abuse and neglect. Recognition and reporting of suspected elder mistreatment by the dermatologist can be life-saving for the older patient.
