Failure of Biologic Therapy in Psoriasis.

OBJECTIVE: This study aims to describe the frequency of biologic therapy failure in psoriasis patients along with associated patient demographics and characteristics. METHODS: This was a retrospective medical-record review of psoriasis patients evaluated from January 1st, 2013, through May 1st, 2018, and who failed at least once to adhere to their biologic therapy. RESULTS: Seventy-seven patients with psoriasis who had discontinued biologic therapy at least once were included in this study. Hypertension (58.4%), diabetes (37.7%), dyslipidemia (27.3%), and psoriatic arthritis (23.4%) were the main comorbidities observed. Adalimumab (ADA, 80.5%), ustekinumab (UST, 70.1%), and etanercept (ETA, 14.2%) were the most frequently used biologics in our cohort. The biologic with the longest mean duration of use prior to its discontinuation was UST (17.0 months), followed by ADA (15.9 months) and ETA (13.6 months). CONCLUSION: The most common reason for discontinuing biologic therapy was that said therapy was not effective, though for ETA and UST, the fact that biologic therapies are not universally covered by insurance company was found to be associated with their discontinuation, as well. There were no statistically significant associations found between biologic therapy discontinuation and age, gender, or comorbidities, which last included obesity, class I. Larger studies are warranted to identify risk factors associated with biologic therapy failure to help guide drug selection, decrease morbidity associated with such nonadherence and improve patient outcomes.

Psoriatic Alopecia in a Patient With Crohn Disease: An Uncommon Manifestation of Tumor Necrosis Factor α Inhibitors.

Tumor necrosis factor α (TNF-α) inhibitors are used to treat multiple inflammatory diseases including rheumatoid arthritis, inflammatory bowel disease, and psoriasis, among others. This family of medications can cause various side effects, some as common as injection-site reactions and others as rare as the paradoxical induction of psoriasiform skin lesions. Alopecic plaques recently have been described as an uncommon adverse effect of the TNF-α inhibitors adalimumab and infliximab. We present the case of a 12-year-old girl treated with adalimumab for Crohn disease who developed an alopecic crusted plaque on the scalp 6 months after increasing the dose of the medication. Biopsies, special stains, and sterile cultures yielded a diagnosis of psoriatic alopecia secondary to TNF-α inhibitor. A literature review for similar cases found 24 additional patients presenting with similar findings, of which only 6 were part of the pediatric population.

Folliculocystic and Collagen Hamartoma: A Distinct Hamartoma Associated With Tuberous Sclerosis Complex.

ABSTRACT: Tuberous sclerosis complex (TSC) is a neurocutaneous disease characterized by cutaneous and extracutaneous hamartomas. Dermatologic evaluation is critical for early diagnosis because mucocutaneous manifestations account for 4 of 11 major and 3 of 6 minor diagnostic criteria. Folliculocystic and collagen hamartoma (FCCH) is a recently described entity associated with TSC. We herein describe the case of a 28-year-old woman with a history of TSC who presented with a scalp lesion present since childhood. Physical examination revealed a solitary, well-circumscribed exophytic tumor over the occipital scalp measuring 9 × 8 cm and covered with comedones and cyst-like structures. Biopsy of the lesion demonstrated thickening of the collagen bundles throughout the dermis, concentric perifollicular and perivascular fibrosis, an increased number of dilated vessels, and keratin-filled cysts lined by the infundibular epithelium. Clinicopathologic correlation was diagnostic for FCCH. The patient was referred for surgical excision. In addition, we review 11 other cases of FCCH previously reported in the literature.

Treatment of erythrodermic psoriasis with biologics: A systematic review.

BACKGROUND: Biologic medications for plaque psoriasis have been used to treat erythrodermic psoriasis (EP). Since the guidelines for management of EP were published, new biologic medications have been approved for the treatment of plaque psoriasis. OBJECTIVE: To analyze the evidence of biologic medications in the treatment of EP based on response and tolerability. METHODS: A comprehensive search was conducted with the PubMed, Cochrane Library, Embase, and Scopus databases through December 31, 2018. Studies reporting 1 or more cases of EP, defined as >75% body surface area involvement, in patients aged ≥18 years treated with biologics were included. Baseline Psoriasis Area and Severity Index score, score improvement, and adverse events were documented. Adequate response to treatment was defined as Psoriasis Area and Severity Index ≥50. RESULTS: Included were 43 articles, yielding a total of 179 patients. Most patients responded at some point during treatment, with a higher level of evidence for infliximab, ustekinumab, ixekizumab, and guselkumab. Infection was the most common adverse event (n = 35). LIMITATIONS: Data are limited to case reports, case series, and uncontrolled studies. CONCLUSION: Patients with EP treated with biologics demonstrated positive responses and treatment was well-tolerated, with a weak recommendation and limited quality of evidence in favor of infliximab, ustekinumab, ixekizumab, and guselkumab.

Biological therapy for pustular psoriasis: a systematic review.

BACKGROUND: The anecdotic evidence of the benefits from biologic agents for psoriasis is extensive. However, data on the efficacy of biologic agents for pustular psoriasis are limited. METHODS: To update the data on the efficacy and safety of biologic agents for the management of pustular psoriasis. A systematic review of published data regarding biologic therapies on PubMED database, used in the management of pustular psoriasis from 2012 was undertaken. RESULTS: A total of 209 articles were identified, and 43 articles were selected for inclusion. TNF-α inhibitors were used in 205 patients, and 86 patients received ustekinumab, secukinumab, brodalumab, ixekizumab and IL-1 inhibitors. Overall response was favorable for most modalities. No serious adverse events were reported. Inconsistent measures of treatment response and study variability limited the overall evaluation of data. CONCLUSIONS: Infliximab and ustekinumab have the most evidence of efficacy and safety for the treatment of pustular psoriasis. Recent evidence supports the use of IL-17 antagonists. Prospective controlled and comparative trials are needed to further explore the efficacy and safety of biologic agents in order to establish objective recommendations for the management of this challenging condition.

Extraocular Sebaceous Carcinoma-A Clinicopathologic Reassessment.

Sebaceous carcinoma is an aggressive adnexal neoplasm with sebaceous differentiation. Few reports have described the histopathologic characteristics of the sebaceous carcinoma occurring extraocularly. Seventy-two cases of extraocular sebaceous carcinoma were identified from the database of a Dermatopathology Laboratory from January 1, 2007 to May 31, 2013. More cases occurred in men (60%), with a mean age at diagnosis of 65.8 years (range 39-99 years). Neoplasms were histopathologically classified as well-differentiated (22%), moderately differentiated (67%), and poorly differentiated (11%). Sixty-seven percent (67%) of cases demonstrated a squamoid growth pattern and thirty-three percent (33%) demonstrated a basaloid growth pattern. A majority of the neoplasms histopathologically classified as well-differentiated (94%) and moderately differentiated (65%) demonstrated a squamoid growth pattern. Ten percent (10%) of cases exhibited cystic histopathologic changes. The histopathological features reported in this study aid in the understanding of extraocular sebaceous carcinoma and its eventual diagnosis and classification.

The effects of regular physical activity on anxiety symptoms in healthy older adults: a systematic review.

OBJECTIVE: Anxiety symptoms are common in older adults with or without anxiety disorders. Pharmacological options may be limited for these patients. Alternative treatments, such as physical activity (PA), are often indicated, although few trials have evaluated their efficacy. The aim of this review was to evaluate the efficacy of regular PA on improving anxiety symptoms in older adults without anxiety disorders. Potential neuroendocrine, inflammatory, and oxidative mechanisms, as well as cognitive factors to explain these effects are also discussed. METHODS: A systematic literature review was performed to identify randomized controlled trials, cross-sectional, cohort, and case-control studies, as well as case series including healthy previously sedentary older adults. We searched the PubMed and Web of Science databases for articles published in English, with no set time limits. RESULTS: Eight studies evaluating the effect of PA on anxiety symptoms in healthy older adults were included in this review. In all studies, regular and supervised PA was directly related to decreased anxiety symptoms in older individuals. CONCLUSION: Regular PA may be effective for improving anxiety symptoms in older adults. More studies are needed to identify the ideal PA modality, frequency, duration, and intensity for optimizing the positive effects of exercise on anxiety in this population.

Treatment-resistant panic disorder: a systematic review.

INTRODUCTION: The prevalence of panic disorder (PD) in the population is high and these patients have work impairment, high unemployment rates, seek medical treatment more frequently and have more hospitalizations than people without panic symptoms. Despite the availability of pharmacological, psychological and combined treatments, approximately one-third of all PD patients have persistent panic attacks and other PD symptoms after treatment. AREAS COVERED: MEDLINE/Pubmed, CENTRAL, PsycINFO and Web of Science databases were searched for clinical trials in treatment-resistant PD. Only studies published between 1980 and 2015, in English, with human subjects, considered "journal articles" and clinical trial were included. We included trials recruiting only adult subjects with treatment-resistant PD, consistent with criteria from DSM-III to DSM5. We included all prospective experimental studies. Case, case series, retrospective studies or studies with <10 PD subjects were not included. EXPERT OPINION: Only 11 articles were included in this review. There were few quality studies, only two were randomized, controlled and double blind. Augmentation of the pharmacological treatment with cognitive-behavioral therapy demonstrated some short-term efficacy in treatment-resistant PD. There were also preliminary evidences of efficacy for monotherapy with reboxetine and olanzapine, and augmentation with pindolol, divalproex sodium, aripiprazole and olanzapine in short-term treatment.

Refractory dissecting Cellulitis of the Scalp Successfully controlled with Adalimumab.

Dissecting cellulitis of the scalp (DCS) is an uncommon inflammatory disease that often results in scarring alopecia. Numerous therapies have either proved ineffective or only temporarily effective in the management of this condition. Recent reports show adequate responses to tumor necrosis factor (TNF) inhibitors in cases of DCS. We report a case of severe recalcitrant DCS successfully treated with adalimumab.

Short-lived response of cervical dystonia to electroconvulsive therapy.

Cervical dystonia (CD) or spasmodic torticollis is the most frequent form of focal dystonia. Cervical dystonia is characterized by sustained neck spasms, abnormal head posture, head tremor, and pain. A 53-year-old male patient with the diagnosis of CD developed an episode of delusional depression and was treated with electroconvulsive therapy (ECT). An unexpected and dramatic improvement of CD was seen during the first 2 days after each ECT session. That therapeutic effect was not sustained and vanished soon afterward. The effectiveness of ECT for CD, although too brief to be recommended as a useful treatment, may shed light on the pathophysiology of this problematic movement disorder.

Focal dermal hypoplasia with unusual cutaneous features.

Focal dermal hypoplasia (Goltz syndrome) is a rare genetic condition characterized by numerous malformations in different organ systems derived from the ectoderm and mesoderm. We present an infant with focal dermal hypoplasia who, besides having a constellation of anomalies commonly encountered in patients with this syndrome, manifested additional unusual features such as an early inflammatory vesicular stage and a cleft lip and palate. We emphasize that a prompt, well-orchestrated and effective multidisciplinary intervention can help improve the quality of life in patients afflicted with this condition.

Modified curettage technique for molluscum contagiosum.

Molluscum contagiosum is a frequently occurring, virally induced cutaneous condition that affects infants, children, and adults. Although historically considered a self-limiting entity, many patients experience prolonged infections, often resistant to varied therapeutic interventions. Topical treatments achieve complete clearance in only a limited number of patients. Because of the associated pain, affected children are characteristically uncompliant to commonly used destructive modalities. We describe a modification of the traditional curettage technique to remove lesions of molluscum contagiosum, which has proven to be effective and well tolerated by a significant number of patients in our practice.

Transtornos parafílicos em pacientes com transtorno obsessivo-compulsivo: série de casos / Paraphilic disorders among patients with obsessive-compulsive disorder: case series

Com o intuito de elucidar a relação entre transtornos do controle de impulsos (TCI) e transtorno obsessivo-compulsivo (TOC), faz-se mister estudar subgrupos mais clinicamente homogêneos de transtornos impulsivos. Por meio do relato de quatro casos de pacientes com TOC e diferentes tipos de transtornos parafílicos (fetichismo transvético, sadismo, ginandromorfofilia e exibicionismo), são discutidos os conceitos de compulsividade, impulsividade e a relação temporal entre ambos. O estudo dos casos aqui descritos mostra que (1) pacientes com TOC e transtornos parafílicos tendem a desenvolver o TOC primeiro, (2) diante de desejos, fantasias ou atos sexuais parafílicos, pacientes com TOC podem lançar mão de comportamentos tipicamente compulsivos, (3) pacientes com TOC e obsessões sexuais egodistônicas podem desenvolver desejos, fantasias ou atos sexuais parafílicos de conteúdo semelhante ao das obsessões, (4) em um mesmo paciente, TOC e parafilias podem apresentar cursos independentes, e (5) pacientes com TOC e parafilias podem não apresentar obsessões sexuais. O sofrimento de pacientes com TOC e parafilias justifica a investigação continuada de tais condições no intuito de elucidar os mecanismos que subjazem esta associação e de criar estratégias que aumentem a adesão ao tratamento.

In order to elucidate the relationship between impulse control disorders and obsessive-compulsive disorder (OCD), it is essential to study more clinically homogenous subgroups of patients with impulsive disorders. Using four cases of patients with OCD and comorbid paraphilias (transvestic fetishism, sadism, gynandromorphophilia, and exhibitionism) as reference-points, we discuss the concepts of compulsivity, impulsivity, and the temporal relationship between them. The case studies here described suggest that (1) patients with OCD and comorbid paraphilias tend to develop OCD first, (2) once developing paraphilic fantasies, desires, or behaviors, patients with OCD can exhibit typical compulsive behaviors in an attempt to keep these phenomena under control, (3) patients with OCD and ego-dystonic sexual obsessions can develop paraphilic fantasies, desires, or behaviors with similar content to the first phenomenon, (4) OCD and paraphilias can follow independent courses in the same patient, and (5) patients with OCD and paraphilias may not present obsessions with sexual content. The distress presented by patients with OCD and paraphilias give good reason for the continuous investigation of this association, aiming at clarifying the neurobiological mechanisms underlying this association.
