ABSTRACT

Despite the significant reduction of both morbidity and mortality after the introduction of many vaccines against COVID-19, recent reports indicated a worsening skin conditions in particular patients with psoriasis. We extracted the data of 51 patients from 19 papers. The mean age was 56.9 (SD = 16.2) years, with a male prevalence 45%. Of the 51 cases, vaccine types at which psoriasis flare occurred were as the following: Pfizer vaccine (30), AstraZeneca (9), Moderna (8), Coronavac (2) Covishield (1), and Covaxin (1). Exacerbation was common in the second dose of Pfizer, AstraZeneca, Moderna, and Covishield vaccines. Moreover, the onset of psoriasis exacerbation was shorter after the second dose of Pfizer (mean = 12.8 [SD = 15.2]) and AstraZeneca (mean = 7.4 [SD = 3.6]) rather than the first dose of both vaccines, respectively (mean = 19.2 [SD = 21.3]) and (mean = 18.5 [SD = 10.7]).

ABSTRACT

The aim of this meta-analysis is to evaluate the safety of dupilumab use in the management of atopic dermatitis (AD) during the current pandemic regarding the risk and the hazards of COVID-19 infection. Seven databases (Google Scholar, Web of Science, Scopus, Virtual Health Library, PubMed, System for Information on Gray Literature in Europe, and The New York Academy of Medicine) were searched for eligible studies from inception until November 24, 2021. The quality of evidence was rated using the National Institute of Health and the Joanna Briggs Institute Critical Appraisal tool. Meta-analysis was performed when the outcome is presented ≥2 studies. A total of 12 papers including 1611 AD patients were included in the study. The prevalence of COVID-19 in AD treated with dupilumab was 3.2% (95% confidence interval [CI]: 1.7-5.8). COVID-19 symptoms were reported by five patients who were presented with one or more of the following symptoms (fatigue, loss of taste and smell, runny nose, conjunctivitis, gastrointestinal symptoms, fever, cough, and dyspnea). Only three cases of COVID-19 were hospitalized with a prevalence of 4.5%, while no patients with COVID-19 died. Dupilumab is safe regarding the risk and the hazards of COVID-19 in AD patients. Thus, based on these results continuation of dupilumab in AD patients is recommended, since dupilumab seems to be safe and crucial for a better disease outcome.

ABSTRACT

BACKGROUND/OBJECTIVE: Relative to adults, rates of melanoma are lower in children. Due to its rarity, it is difficult to assess the incidence, trends, and outcomes of this malignancy. Much of our understanding comes from single institution or regional cancer registries which may not be large enough to detect subtleties in the burden of pediatric melanoma. METHODS: Data from the 2004 to 2016 National Cancer Database were analyzed; this database captures approximately 70% of all cancer diagnoses in the United States. RESULTS: Our analysis consisted of 1903 cases. A majority were White (89.8%), the mean age was 12.4 years, and the ratio of females: males was 1.2:1.0. The most common anatomic location was the trunk (31.1%). Between 2004 and 2016, a decreasing trend in the number of new melanoma cases was observed. Comparing histologic subtype by age, there was an increased percentage of nodular and epithelioid and spindle cell tumors in the pre-teen children and a greater percentage of superficial spreading tumors in teenagers. Overall, a majority of cases were stage 0 or I (56.9%), with relatively few stage IV cases (2.0%). A 5-year all-cause survival of greater than 90% was observed for stage I-III tumors, with stage IV tumors having a 5-year all-cause survival of 34.4%. CONCLUSION: Comparable to previous studies, pediatric melanoma occurred most often in Whites, females, and adolescents. However, we detected a decreasing trend in new cases, noted differences between histologic subtype and age, and observed a 5-year all-cause survival rate of greater than 90% for stage I-III tumors.

ABSTRACT

BACKGROUND: Systemic biologic and nonbiologic agents used to treat psoriasis may or may not contribute to serious infection (SI) risk. Safety data, particularly for biologic agents, and associated risk for SI, are scarce. The study's aim was to explore the risk for SI in psoriasis patients exposed to systemic biologic or nonbiologic agents. METHODS: A large, single-center electronic medical record repository was searched between January 2010 and December 2014. Records for patients prescribed a systemic agent for psoriasis (SAP) with psoriasis or psoriatic arthritis diagnoses were included (ICD-9 codes 696.1 and 696.0, respectively). SIs were those who required hospitalization, and/or injectable antibacterial, antiviral or antifungal therapy. SIs occurring within 120 days after exposure to a SAP, were included for study. RESULTS: A total of 1,346 patients were exposed to a SAP between January 2010 and December 2014; 27 (2%) had a SI. Comparing biologic and nonbiologic agent exposure, no statistically significant difference for risk of SI was detectable (p = .83). CONCLUSION: In this population, the SI rate for biologic and nonbiologic systemic agents was clinically indistinguishable, thereby supporting consideration of the entire spectrum of available systemic therapeutic agents, both biologic and nonbiologic agents, for management of moderate to severe psoriasis.

ABSTRACT

BACKGROUND: Pemphigus is a group of debilitating autoimmune blistering disorders associated with painful blisters of the skin and/or mucous membranes. Identification and management of the comorbiditiesof pemphigus is critically important to minimize morbidity and decrease mortality. OBJECTIVE: To identify the comorbid health conditions of pemphigus vulgaris. METHODS: This was a case-control study of 130 cases of pemphigus verified by a clinical and laboratory diagnosis and 390 age and sex-matched controls with complete follow-up at a large metropolitanquaternary care medical center. RESULTS: Pemphigus vulgaris and its treatments were significantly associated with type 2 diabetes mellitus (adjusted odds ratio [95% confidence interval]: 5.68 [2.93-11.02]), hypertension (2.15 [1.25-3.71]), osteopenia (10.07 [3.72-27.25]), osteoporosis (4.19 [1.50-11.73]), cataracts (7.00 [1.81-27.07]), insomnia (15.00 [1.75-128.39]), and benign prostatic hyperplasia (6.84 [1.79-26.18]). A history of taking systemic corticosteroids was found in 76% of pemphigus vulgaris patients. There were significant statistical interactions between pemphigus vulgaris and a history of using systemic corticosteroids as predictors of diabetes mellitus type 2, hypertension, osteoporosis, and insomnia. CONCLUSIONS: Safer and more effective systemic treatment options are needed for pemphigus to minimize iatrogenic complications of disease.

ABSTRACT

BACKGROUND: Individuals with high-level spinal cord injuries need effective ways to perform activities. OBJECTIVES: To develop and test a medically supervised tongue-piercing protocol and the wearing of a magnet-containing tongue barbell for use with the Tongue Drive System (TDS) in persons with tetraplegia. METHODS: Volunteers with tetraplegia underwent initial screening sessions using a magnet glued on the tongue to activate and use the TDS. This was followed by tongue piercing, insertion of a standard barbell, a 4-week healing period, and an exchange of the standard barbell for a magnet-containing barbell. This was then used twice weekly for 6 to 8 weeks to perform computer tasks, drive a powered wheelchair, accomplish in-chair weight shifts, and dial a phone. Symptoms of intraoral dysfunction, change in tongue size following piercing, and subjective assessment of receiving and wearing a magnet-containing tongue barbell and its usability with the TDS were evaluated. RESULTS: Twenty-one volunteers underwent initial trial sessions. Thirteen had their tongues pierced. One individual's barbell dislodged during healing resulting in tongue-tract closure. Twelve had the barbell exchanged for a magnet-containing barbell. One subject withdrew for unrelated issues. Eleven completed the TDS testing sessions and were able to complete the assigned tasks. No serious adverse events occurred related to wearing or using a tongue barbell to operate the TDS. CONCLUSIONS: Using careful selection criteria and a medically supervised piercing protocol, no excess risk was associated with tongue piercing and wearing a tongue barbell in people with tetraplegia. Participants were able to operate the TDS.

ABSTRACT

The incidences of life-threatening toxicities such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are inconsistently reported. The potential association of anticancer agents with SJS or TEN has not been systematically investigated. We searched the literature (Ovid: 1950 to June 2013 and PubMed: 1948 to June 2013) using terms for SJS/TEN and anticancer therapies. Primary case reports, case series, and clinical trials were included. In addition, MedWatch, the Food and Drug Administration Adverse Event Reporting System (FAERS), was searched (1968 to August 2012) for SJS/TEN reports associated with anticancer therapies. Proportional reporting ratios (PRR>2, N>3), empirical Bayes geometric mean (EBGM>2, N>3), and lower 95% confidence interval (EBGM0.05>2) were used as thresholds to constitute a signal of association between SJS/TEN and anticancer drugs. There were 46 SJS and 37 TEN cases associated with 18 and 22 anticancer drugs in the literature, respectively. Among cases in the FAERS, significant signals were associated with SJS for bendamustine and with TEN for bendamustine, busulfan, chlorambucil, fludarabine, lomustine, and procarbazine. Several drugs reported in the published literature to be associated with SJS/TEN were not found to have significant signals in FAERS. Proactive pharmacovigilance to detect and define safety signals serves to aid oncology practitioners in the recognition of possible, yet uncommon, serious, and/or life-threatening skin reactions.

ABSTRACT

A 56-year-old woman with hypertension-induced end stage renal disease presented with skin thickening and mottled discoloration. Cutaneous biopsy showed increased dermal fibroblasts embedded in fibromyxoid stroma with scattered perivascular and interstitial mononuclear cells. Immunohistochemistry revealed prominent CD34+ dendritic cells in septal spaces, consistent with Nephrogenic Systemic Fibrosis (NSF). Seven years and two years prior she had received a gadolinium-based contrast agent (GBCA). She died due to NSF. Gross autopsy revealed a thickened and stenotic superior vena cava (SVC). Extensive fibrosis of the SVC, dermis, and subcutaneous tissue was noted, together with hyalinized collagen fibers within the muscular wall of the intestines and dura mater. These findings support the importance of skin changes in the recognition of life threatening extracutaneous tissue involvement in NSF.

ABSTRACT

BACKGROUND: Nephrogenic systemic fibrosis is a fibrosing disorder associated with exposure to gadolinium-based contrast agents in people with severely compromised renal function. OBJECTIVE: The purpose of this study was to determine the reported number of cases of nephrogenic systemic fibrosis in children using three distinct publicly available data sources. MATERIALS AND METHODS: We conducted systematic searches of the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS), the International Center for Nephrogenic Systemic Fibrosis Research (ICNSFR) registry and published literature from January 1997 through September 2012. We contacted authors of individual published cases to obtain follow-up data. Data sets were cross-referenced to eliminate duplicate reporting. RESULTS: We identified 23 children with nephrogenic systemic fibrosis. Seventeen had documented exposure to gadolinium-based contrast agents. Six children had been reported in both the FAERS and the literature, four in the FAERS and the ICNSFR registry and five in all three data sources. CONCLUSION: Nephrogenic systemic fibrosis has been rarely reported in children. Although rules related to confidentiality limit the ability to reconcile reports, active pharmaco-vigilance using RADAR (Research on Adverse Drug events And Reports) methodology helped in establishing the number of individual pediatric cases within the three major data sources.

ABSTRACT

BACKGROUND: Referral of patients with heart failure (HF) who are at high mortality risk for specialist evaluation is recommended. Yet, most tools for identifying such patients are difficult to implement in electronic health record (EHR) systems. OBJECTIVE: To assess the performance and ease of implementation of Machine learning Assessment of RisK and EaRly mortality in Heart Failure (MARKER-HF), a machine-learning model that uses structured data that is readily available in the EHR, and compare it with two commonly used risk scores: the Seattle Heart Failure Model (SHFM) and Meta-Analysis Global Group in Chronic (MAGGIC) Heart Failure Risk Score. DESIGN: Retrospective, cohort study. PARTICIPANTS: Data from 6764 adults with HF were abstracted from EHRs at a large integrated health system from 1/1/10 to 12/31/19. MAIN MEASURES: One-year survival from time of first cardiology or primary care visit was estimated using MARKER-HF, SHFM, and MAGGIC. Discrimination was measured by the area under the receiver operating curve (AUC). Calibration was assessed graphically. KEY RESULTS: Compared to MARKER-HF, both SHFM and MAGGIC required a considerably larger amount of data engineering and imputation to generate risk score estimates. MARKER-HF, SHFM, and MAGGIC exhibited similar discriminations with AUCs of 0.70 (0.69-0.73), 0.71 (0.69-0.72), and 0.71 (95% CI 0.70-0.73), respectively. All three scores showed good calibration across the full risk spectrum. CONCLUSIONS: These findings suggest that MARKER-HF, which uses readily available clinical and lab measurements in the EHR and required less imputation and data engineering than SHFM and MAGGIC, is an easier tool to identify high-risk patients in ambulatory clinics who could benefit from referral to a HF specialist.
