The management of pediatric hidradenitis suppurativa differs between dermatologic and non-dermatologic providers: A retrospective review.

BACKGROUND/OBJECTIVES: There is a paucity of pediatric hidradenitis suppurativa (HS) literature. The objective of this study was to characterize differences in management of pediatric HS patients by dermatology versus non-dermatology clinicians. METHODS: We examined a retrospective cohort of 195 pediatric patients with HS seen at our institution (3/1/19-3/1/20). Two-sample t-tests and two-proportion z-tests were performed. RESULTS: A total of 76.1% of subjects were seen by dermatology at least once, and of these, 79.1% were referred. HS diagnosis was most often made by dermatology (36.6%), followed by pediatrics (21.6%). Patients managed by dermatology were significantly more likely to have used standard of care therapies (p < .001). Of dermatology-managed patients, 19.7% were currently prescribed a biologic, as compared with zero patients not managed by dermatology. Those managed by dermatology were less likely to undergo surgical excision (13.3% vs. 25.5%, p = .04). CONCLUSIONS: Our results support increased likelihood of treatment escalation with medical management by dermatologists. Relatively high utilization of referral to dermatology exists, but with only moderate patient adherence. There is a need for improved access to dermatologic care and prospective studies to determine whether differences in specialty management translate to improved patient outcomes.

Eye Disease Prevalence and VF-14 Validation Among Patients Experiencing Homelessness and Presenting for Ophthalmic Examination in Baltimore, Maryland.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic is projected to drive 1.5 million Americans toward homelessness, adding to the 3.5 million currently affected. Homelessness poses both socioeconomic and public health challenges because housing status is a social determinant of health. Given ophthalmic health's importance in daily functioning, we characterized ophthalmic disease and vision-related quality of life (VRQOL) among a population experiencing homelessness in Baltimore, Maryland. Methods: Questionnaires, including a Visual Function Index-14 (VF-14) for measuring VRQOL, were administered among patients seeking eye examinations at Health Care for the Homeless (HCH) from October 2018 to March 2020. Results: One hundred sixty-two participants were enrolled in this study. The average age was 53 years. Participants' most common vision concerns were blurry vision (70%) and desire for glasses (52%). Best corrected visual acuity (BCVA) measurements revealed significant vision loss (18%, P < 0.001). Physicians mostly diagnosed refractive error (77%), cataracts (36%), glaucoma/glaucoma suspect (25%), and dry eye (24%). Nearly half were referred to additional ophthalmic care (46%). VRQOL trends reflected functional vision categories (P = 0.042 and P = 0.021). The 1:1 VRQOL and BCVA comparison showed correlation (rho = -0.3, P < 0.001). Cronbach's alpha demonstrated VF-14 reliability (alpha = 0.92). Conclusions: We find high ophthalmic disease prevalence within a population experiencing homelessness. Comparison to studies worldwide reveals healthcare disparities despite healthcare system differences, suggesting a need for more targeted solutions. VF-14 is valid and reliable in assessing those experiencing homelessness. Intragroup VRQOL comparisons may reveal subgroup needs. It is imperative that future studies continue monitoring those experiencing homelessness. Translational Relevance: Validation of VF-14 will allow future studies to utilize this patient-oriented metric within populations experiencing homelessness.

Applications of Laser Speckle Contrast Imaging Technology in Dermatology.

Laser speckle contrast imaging or laser speckle imaging (LSI) is a noninvasive imaging technology that can detect areas of dynamic perfusion or vascular flow. Thus, LSI has shown increasing diagnostic utility in various pathologies and has been employed for intraoperative, postoperative, and long-term monitoring in many medical specialties. Recently, LSI has gained traction in clinical dermatology because it can be effective in the assessment of pathologies that are associated with increased perfusion and hypervascularity compared with that of normal tissue. To date, LSI has been found to be highly accurate in monitoring skin graft reperfusion, determining the severity of burns, evaluating neurosurgical revascularization, assessing persistent perfusion in capillary malformations after laser therapy, and differentiating malignant and benign skin lesions. LSI affords the advantage of noninvasively assessing lesions before more invasive methods of diagnosis, such as tissue biopsy, while remaining inexpensive and exhibiting no adverse events to date. However, potential obstacles to its clinical use include tissue movement artifact, primarily qualitative data, and unclear impact on clinical practice given the lack of superiority data compared with the current standard-of-care diagnostic methods. In this review, we discuss the clinical applications of LSI in dermatology for use in the diagnosis and monitoring of vascular, neoplastic, and inflammatory skin conditions.

The far-reaching burden of Hyperemesis Gravidarum - an exploration of women's experiences and perceptions of healthcare support.

Hyperemesis Gravidarum (HG) is a rare condition of pregnancy that exerts a profound effect on a woman's physical and psychological health, but limited research regarding women's perceptions of healthcare for this condition exists. The aim of this study was to gain insight into the personal and healthcare experiences of women with HG. Eligible participants included women who had experienced HG in a current or recent pregnancy and were referred to the dietitian at the National Maternity Hospital, Dublin, Ireland. Suitable women were invited to participate by letter, with a follow-up phone call to confirm eligibility. Four semi-structured focus groups were conducted (n = 11). Audio recordings were transcribed and data was thematically analyzed using an inductive, data-driven approach. Participants emphasized the psychological hardship of HG, which manifested in many different ways, and unveiled the far-reaching burden of HG. Women advocated for a dedicated service for HG and the need for increased knowledge, understanding and support for HG, in order to ensure optimal HG management and woman-centered care. Women also highlighted the need for obvious clinical leadership of HG and a continuum of care throughout pregnancy and post-partum. Improvements to the day ward setting and access to HG-specific mental health support would be welcomed. At a government level, timely resolution of the financial assistance for first-line anti-emetics is needed. Overall, greater awareness and understanding of the condition is needed to improve support from family, friends and colleagues. Further research is warranted to determine whether these recommendations would result in improved pregnancy outcomes.

Identifying risk factors for cutaneous disease among solid organ transplant recipients: A retrospective review.

Background: As solid organ transplant recipient (SOTR) life expectancy lengthens, the risk of developing other chronic diseases also increases. Objective: To determine the cutaneous pathologies for which SOTRs are at an increased risk. Methods: We performed a retrospective review of SOTRs seen by dermatology from January 1, 2012 and June 1, 2022. Data were analyzed using multivariate logistic regression. Benjamini Hochberg-adjusted P values were examined for multiplicity. Results: Five hundred and thirty SOTRs were identified. Patients had cutaneous malignancy (38.3%), precancerous lesions (32.5%), inflammatory (35.5%), and infectious diseases (33.1%). Odds of precancerous lesions were higher with increased age at transplant (odds ratio [OR], 1.04; adjusted P =.006), and lower with female sex (OR, 0.505; adjusted P =.006) and African American race (OR, 0.027; adjusted P =.006). Odds of inflammatory lesions were lower with increased age at transplant (OR, 0.979; adjusted P =.023). Odds of infectious diseases were higher with prednisone use (OR, 2.615; adjusted P value =.023). Limitations: This study is retrospective and was not able to capture patients seen by dermatology outside of our institution. Conclusions: SOTRs at risk of cutaneous lesions should be referred to dermatology because these conditions may place a significant burden on the quality of life.

Reducing Nonemergent Visits to the Emergency Department in a Veterans Affairs Multistate System.

STUDY OBJECTIVE: The purpose of this quality improvement study was to reduce nonemergent visits to the emergency department attendance within a multistate Veterans Health Affairs network. METHODS: Telephone triage protocols were developed and implemented for registered nurse staff to triage selected calls to a same-day telephonic or video virtual visit with a provider (physician or nurse practitioner). Calls, registered nurse triage dispositions, and provider visit dispositions were tracked for 3 months. RESULTS: There were 1606 calls referred by registered nurses for provider visits. Of these, 192 were initially triaged as emergency department dispositions. Of these, 57.3% of calls that would have been referred to the emergency department were resolved via the virtual visit. Thirty-eight percent fewer calls were referred to the emergency department following licensed independent provider visit compared to the registered nurse triage. CONCLUSION: Telephone triage services augmented by virtual provider visits may reduce emergency department disposition rates, resulting in fewer nonemergent patient presentations to the emergency department and reducing unnecessary emergency department overcrowding. Reducing nonemergent attendance to emergency departments can improve outcomes for patients with emergent dispositions.

Comparison of Patient and Provider Practices between Bone Marrow and Solid Organ Transplantation Programs for Patient Education on Increased Risk of Skin Cancer.

Patients receiving immunosuppressive therapy following transplantation are at risk for skin cancer owing to dampened tumor surveillance. As long-term immunotherapy is necessary to prevent graft rejection, transplantation providers and recipients are expected to perform regular surveillance for the development of suspicious lesions, and recipients are encouraged to practice preventative sun safe behaviors. No consensus exists regarding the timing of full body skin exams, and despite the well-established risk, patient education is not always prioritized. We investigated whether differences exist between bone marrow transplant (BMT) and organ transplant (OT) recipients and their providers regarding prevention and screening. We distributed surveys to adult and pediatric BMT and OT recipients, as well as their providers, at a single academic institution. Results were evaluated using the chi-square test. The survey results show that most BMT recipients (69%) and OT recipients (77%) were aware of their increased risk for skin cancer, but despite this knowledge, only 13% of patients overall reported using sunscreen, 29% reported reapplying sunscreen, and 48% reported wearing sun protective clothing. Most OT recipients (63%) reported never having a total body skin exam, whereas only 34% BMT recipients reported having a total body skin exam every 6 months (P = .006). BMT providers recommended a total body skin exam every 6 or 12 months (44.4% each), and OT providers recommended a total body skin exam every 12 months (58.3%). Only 11.1% of BMT providers and 8.3% of OT providers reported performing a total body skin exam at each visit. Despite results indicating widespread patient knowledge of skin cancer risk, most patients do not practice adequate prevention. Inclusion of a transplantation dermatologist in the care team or use of risk stratification tools by providers may help streamline timely referrals to Dermatology.

Re-evaluating the need for chronic toxicity studies with therapeutic monoclonal antibodies, using a weight of evidence approach.

To support registration of monoclonal antibodies (mAbs) for chronic indications, 6-month toxicity studies have historically been conducted. Experience with mAb development has shown a relatively benign and well-understood safety profile for this class, with most toxicity findings anticipated based on pharmacology. We evaluated whether a 6-month toxicity study is necessary to assess the long-term safety of mAbs. Data on First-in-Human (FIH)-enabling and chronic toxicity studies were shared for 142 mAbs submitted by 11 companies. Opportunities to further optimize study designs to reduce animal usage were identified. For 71% of mAbs, no toxicities or no new toxicities were noted in chronic studies compared to FIH-enabling study findings. New toxicities of potential concern for human safety or that changed trial design were identified in 13.5% of cases, with 7% being considered critical and 2% leading to program termination. An iterative, weight-of-evidence model which considers factors that influence the overall risk for a mAb to cause toxicity was developed. This model enables an evidence-based justification, suggesting when 3-month toxicity studies are likely sufficient to support late-stage clinical development and registration for some mAbs.

The use of recovery animals in nonclinical safety assessment studies with monoclonal antibodies: further 3Rs opportunities remain.

Assessment of reversibility from nonclinical toxicity findings in animals with potential adverse clinical impact is required during pharmaceutical development, but there is flexibility around how and when this is performed and if recovery animals are necessary. For monoclonal antibodies (mAbs) and in accordance with ICH S6(R1) if inclusion of recovery animals is warranted, this need only occur in one study. Data on study designs for first-in-human (FIH)-enabling and later-development toxicity studies were shared from a recent collaboration between the NC3Rs, EPAA, Netherlands Medicines Evaluation Board (MEB) and 14 pharmaceutical companies. This enabled a review of practices on recovery animal use during mAb development and identification of opportunities to reduce research animal use. Recovery animals were included in 68% of FIH-enabling and 69% of later-development studies, often in multiple studies in the same program. Recovery groups were commonly in control plus one test article-dosed group or in all dose groups (45% of studies, each design). Based on the shared data review and conclusions, limiting inclusion of recovery to a single nonclinical toxicology study and species, study design optimisation and use of existing knowledge instead of additional recovery groups provide opportunities to further reduce animal use within mAb development programs.

Characterizing Skin Cancer in Transplant Recipients by Fitzpatrick Skin Phototype.

INTRODUCTION: Nearly half of organ transplants occur annually in patients with Fitzpatrick skin phototypes (Fitz type) III-VI. Organ transplant recipients (OTRs) are at risk for sequelae of chronic immunosuppression, of which skin cancer is common. As literature regarding skin cancer risk is largely conducted in OTRs with Fitz types I and II, we aimed to further characterize the incidence and risk factors for skin cancer in OTRs with higher Fitz types. METHODS: We conducted a retrospective review of OTRs with Fitz types III-VI evaluated by dermatology between 1 January 2012 and 1 June 2022. The primary outcome of this study was development of skin cancer post-transplant. Secondary outcomes included risk factors for skin cancer development. Data were analyzed using two-sample t-tests and Pearson's chi-squared. RESULTS: Of 530 OTRs, 193 had Fitz type III or higher. Ten patients (5.18%) developed 87 skin cancers and one recurrence at a mean of 5.17 years posttransplant. Patients with skin cancer self-identified as Black (70%, p-value ≤ 0.001), male (70%, p-value ≤ 0.001), and kidney transplant recipients (70%, p-value ≤ 0.001), with a mean age of 58.20 years at transplant (p-value ≤ 0.001). Subjects with skin cancer were more likely to be former smokers (60%) and prescribed tacrolimus (p-value ≤ 0.001 each). Development of cutaneous squamous cell carcinoma (66, 75.86%) was most common, followed by basal cell carcinoma (17, 19.54%), and malignant melanoma (3, 3.45%). Skin cancer most often occurred on the face or scalp (60%, p-value = 0.027), though also developed in sun-protected sites (30%, p-value = 0.002). Verruca vulgaris was present in 10% of patients (p-value = 0.028). CONCLUSIONS: Risk factors for skin cancer post-transplant differ in OTRs with higher Fitz types. Our results suggest that among OTRs who self-identified as Black, kidney recipients are at increased risk for skin cancer in non-sun-exposed regions. These cancers may be associated with human papillomavirus (HPV). Education is key for preventing morbidity and mortality secondary to skin cancer.

Vascular Anomalies: Nomenclature and Diagnosis.

Before the development of the International Society for the Study of Vascular Anomalies (ISSVA) classification system in 1996, nomenclature used to describe vascular lesions was inconsistent and imprecise. This since widely adopted system stratifies vascular anomalies into vascular malformations and tumors. Vascular tumors involve abnormal proliferation of vascular cells and are further classified as benign, locally aggressive/borderline, or malignant. Vascular malformations are lesions of defective vascular morphogenesis with quiescent endothelium and are named according to their vessel composition, and subdivided into simple; combined, of major named vessels; and syndrome-associated malformations. The updated 2018 ISSVA criteria are referenced in this review.

Trajectory of self-care in people with stable heart failure and insomnia after two self-care interventions.

OBJECTIVE: To describe (1) self-care trajectories among adults with heart failure (HF) and insomnia over 1-year; (2) the extent to which trajectories varied between cognitive behavioral therapy for insomnia (CBT-I) or HF self-care intervention; and (3) the associations between self-care trajectories and clinical and demographic characteristics, sleep, symptoms and stress, and functional performance. METHODS: We conducted secondary analysis of data from a randomized controlled trial of the effects of CBT-I compared with HF self-care education among adults with stable HF and insomnia. We used the Self-Care of Heart Failure Index v6.2. The analytic approaches included t-tests, group-based trajectory modeling, ANOVA, and chi-square. RESULTS: We included 175 participants (M age=63.0 (12.9) years, White, N = 100]. We found four self-care trajectories: Low self-care (N = 47, 26.8%); Moderate self-care (N = 68, 38.9%): Adequate self-care (N = 42, 24.0%); and Optimal self-care (N = 18, 10.3%). There was no difference in self-care trajectories between interventions. The low self-care group had the most severe baseline fatigue, anxiety, and perceived stress, and lowest cognitive abilities. CONCLUSION: Both interventions prevented declining self-care. Future research is needed to determine the most efficacious intervention to improve self-care trajectories. PRACTICE IMPLICATIONS: Healthcare providers should provide ongoing self-care support for those with persistently low and moderate self-care.
