Analysis of Spin in the Reporting of Studies of Topical Treatments of Photoaged Skin

Motosko, Catherine C; Ault, Anna K; Kimberly, Laura L; Gothard, M David; Ho, Roger S; Hazen, Alexes
BACKGROUND:Spin-reporting that distorts the interpretation of results-is not unusual within scientific literature. OBJECTIVE:To appraise strategies of spin among placebo-controlled double-blind clinical trials of topical treatments for photoaged skin. METHODS:A systematic review of literature was performed to identify placebo-controlled double-blind clinical trials of topical treatments for photoaged skin. A survey of spin strategies was developed and applied to the cohort of identified studies. RESULTS:Systematic review identified 20 studies, all of which employed various spin strategies, broadly classified as either inappropriate statistical analysis or inappropriate interpretation of results. Most commonly used strategies included use of multiple primary outcomes (95%), inappropriate extrapolation of the results from specific outcome to global improvement (95%), focus on within-group comparison (75%), and focus on interim analyses to give more weight to nonsignificant findings (65%). LIMITATIONS/CONCLUSIONS:Classification of spin strategies is subjective and may not encompass all methods used by studies in the published literature. CONCLUSIONS:Findings in this study may inform efforts to reduce spin in the dermatologic literature.

Using Google to Trend Patient Interest in Botulinum Toxin and Hyaluronic Acid Fillers

Motosko, Catherine; Zakhem, George; Ho, Roger; Saadeh, Pierre; Hazen, Alexes
Introduction: Google Search is an important tool for patients researching skin care treatments and finding dermatologists. Data from individual patient’s searches are aggregated by Google and yield powerful data sets that can be used to trend population behaviors. This study investigates the correlations between the volume of Google searches and the number of procedures performed annually for both botulinum toxin type A and hyaluronic acid tissue fillers.

Psoriasis and Suicidality: A Review of the Literature

Liang, Sydney E; Cohen, Jeffrey M; Ho, Roger S
Psoriasis is a chronic systemic inflammatory skin disease, which has been associated with an increased risk of numerous medical and psychiatric comorbidities, including suicidality. Suicidality, which can be divided into the categories of suicidal ideation, suicide attempt, and completed suicide, is highly prevalent in the psoriasis population, and multiple studies have been published on the subject of psoriasis and suicidal ideation and behavior (SIB), including two recent meta-analyses. However, the available literature is limited and inconsistent, and the association between the two remains incompletely understood. The present review aims to cohesively synthesize and summarize the available evidence, while making a clinically relevant distinction between the sub-categories of suicidality, by examining not only the epidemiology of the association but also the plausible molecular mechanisms and the potential influence of biologic therapies. Additionally, this review aims to critically examine and understand the potential contribution of depression in the psoriasis and suicidality relationship. This will allow us to better understand the complex and multi-faceted relationship between psoriasis and suicidality, to identify those who may be most at risk for SIB, to make evidence-based clinical decisions regarding treatment and management, and to more completely address the needs of psoriasis patients.

Severe Oral Mucositis: A Rare Adverse Event of Pembrolizumab

Lederhandler, Margo H; Ho, Anthony; Brinster, Nooshin; Ho, Roger S; Liebman, Tracey N; Lo Sicco, Kristen
Treatment of malignancy with anti-programmed cell death 1 (PD-1) immune checkpoint inhibitors can cause mucocutaneous side effects resulting from T cell activation. Due to their recent development, the full side effect profile remains to be fully elucidated, however dermatologic adverse events are most common. The main oral toxicities of these immune checkpoint inhibitors include: xerostomia, dysgeusia, and lichenoid reactions. Oral mucositis occurs more rarely in the setting of PD-1 inhibition, and few other reports of a Grade 3 or higher, severe, stomatitis have been reported in the literature. We present a case of a 78-year-old woman with Grade 3 ulcerative oral mucositis that occurred 13 months after initiation of PD-1 inhibitor, pembrolizumab, for the treatment for lung adenocarcinoma. She was successfully treated with prednisone, and pembrolizumab was temporarily held by her oncologist. Physicians should be aware of the possibility of severe mucositis in the setting of PD-1 inhibitors, as well as the management. J Drugs Dermatol. 2018;17(7):807-809.

Cowden syndrome presenting with trichilemmomas

Ng, Elise; Terushkin, Vitaly; Meehan, Shane A; Ho, Roger; Pomeranz, Miriam Keltz
Cowden syndrome (CS) is a genetic cancerpredisposition syndrome that is associated withgermline mutations in the phosphate and tensinhomologue deleted on chromosome ten (PTEN)tumor suppressor gene. It is characterizedby the formation of benign and malignanttumors. Characteristic benign tumors includetrichilemmommas, acral keratoses, mucocutaneousneuromas, and oral papillomas. The most commonmalignant condition include breast, thyroid, andendometrial cancers. We present a case of a30-year-old woman with CS, who initially presentedwith trichilemmomas that were misdiagnosed ascomedonal acne. Recognition of the presentingfeatures of CS is important to ensure proper referral,management, and treatment for these patients.

Scrotal lymphangioma circumscriptum

Feng, Hao; Kim, Randie H; Brinster, Nooshin; Ho, Roger; Pomeranz, Miriam Keltz
Lymphangioma circumscriptum (LC) is anuncommon, benign, cutaneous disorder thatinvolves lymphatic dilatation to cause vesicularand papular lesions on the trunk, extremities, andanogenital areas. It may be a diagnostic challengewhen appearing in the anogenital region andoften is misdiagnosed and mistreated as infectiousetiologies, which include molluscum contagiosumand condylomata accuminata. We report a healthy40-year-old man with a six-month history of aneruption of multiple, asymptomatic, scrotal papulesthat were diagnosed as lymphangiomas. Awarenessof scrotal LC in adult men without prior disease orsymptoms is necessary for proper diagnosis andavoidance of unnecessary treatment.

Psoriasis and the Risk of Depression in the US Population: National Health and Nutrition Examination Survey 2009-2012

Cohen, Brandon E; Martires, Kathryn J; Ho, Roger S
IMPORTANCE: Psoriasis is a risk factor for depression. Depression may also trigger or exacerbate psoriasis. The relationship between psoriasis and depression, however, remains to be fully explored. OBJECTIVE: To investigate the association between psoriasis and major depression in the US population. DESIGN, SETTING, AND PARTICIPANTS: Population-based study using participants in the National Health and Nutrition Examination Survey from 2009 through 2012. MAIN OUTCOMES AND MEASURES: Diagnosis of major depression based on the Patient Health Questionnaire-9. RESULTS: We identified 351 (2.8%) cases of psoriasis and 968 (7.8%) cases of major depression among 12382 US citizens included in our study. Fifty-eight (16.5%) patients with psoriasis met criteria for a diagnosis of major depression. The mean (SD) Patient Health Questionnaire-9 score was significantly higher among patients with a history of psoriasis than those without psoriasis (4.54 [5.7] vs 3.22 [4.3], P < .001). Psoriasis was significantly associated with major depression, even after adjustment for sex, age, race, body mass index, physical activity, smoking history, alcohol use, history of myocardial infarction (MI), history of stroke, and history of diabetes mellitus (OR, 2.09 [95% CI, 1.41-3.11], P < .001). Interaction term analyses involving patients with a history of both psoriasis and a cardiovascular event, specifically MI or stroke, did not reveal a synergistically increased risk of major depression (psoriasis and MI: OR, 1.09 [95% CI, 0.28-3.60], P = .91; psoriasis and stroke: OR, 0.67 [95% CI, 0.12-3.66], P = .63). In adjusted multivariable models, the risk of major depression was not significantly different between patients with limited vs extensive psoriasis (OR, 0.66 [95% CI, 0.18-2.44], P = .53). CONCLUSIONS AND RELEVANCE: Self-reported history of psoriasis was independently associated with major depression as assessed by a validated screening tool, even when controlling for comorbidities. History of cardiovascular event did not modify the risk of major depression for patients with psoriasis. The severity of psoriasis was unrelated to the risk of major depression. Therefore, all patients with psoriasis, regardless of severity, may be at risk for major depression.
