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.

The Utility of the Paramedian Forehead Flap in Lower Eyelid Reconstruction.

BACKGROUND: Malignant cutaneous eyelid tumors account for approximately 10% of all cutaneous cancers. Like other cancerous skin lesions, treatment commonly involves excision with wide margins, requiring tissue reconstruction. The use of the paramedian forehead flap (PMFF) has been described for reconstruction of the medial and upper eyelid, but literature is lacking for its use in lower eyelid anterior lamella reconstruction. We present a case series of patients who underwent reconstruction of lower eyelid defects using the PMFF. CASE PRESENTATIONS: We present 2 patients who underwent reconstruction of lower eyelid defects using the PMFF surgical technique. The patients had previous history of lower lid repair with other reconstructive methods because of cancerous eyelid lesions. In addition, both received adjuvant radiation therapy, which led to development of ectropion. Postoperative signs, symptoms, and photographs were collected to monitor outcomes. MANAGEMENT AND OUTCOMES: Reconstructions were performed by the collaborative efforts of a facial plastic reconstructive surgeon and oculoplastic surgeon using a staged PMFF approach. Postoperatively, both patients had significant improvement in ophthalmologic symptoms, particularly ectropion and lagophthalmos. At their most recent follow-up visit, they were satisfied with their functional and aesthetic outcomes. CONCLUSION: The PMFF may be safely used to reconstruct defects of the lower eyelid anterior lamella. In this study, the PMFF has proven to be an excellent option for patients with complications after previous lower eyelid reconstructions or history of radiation therapy. Overall, the PMFF should be considered as part of the surgeon's reconstructive ladder when addressing lower eyelid defects.

Prevalence of allergic contact dermatitis in children with and without atopic dermatitis: A multicenter retrospective case-control study.

BACKGROUND: As both allergic contact dermatitis and atopic dermatitis (AD) have similar clinical presentations and are characterized by spongiotic dermatitis on skin biopsy, many children with AD are not referred for patch testing and allergic contact dermatitis is underdiagnosed. OBJECTIVE: To provide updated prevalence data of common contact allergens in children with and without AD. METHODS: This is a retrospective case-control study using the Pediatric Allergic Contact Dermatitis Registry from 2018 to 2022. RESULTS: A total of 912 children were included (615 with AD and 297 without AD). Children with AD were more likely to have a longer history of dermatitis (4.1 vs 1.6 years, P < .0001), have seen more providers (2.3 vs 2.1, P = .003), have greater than 1 positive patch test (PPT) result (P = .005), have a greater number of PPT results overall (2.3 vs 1.9, P = .012), and have a more generalized distribution of dermatitis (P = .001). PPT to bacitracin (P = .030), carba mix (P = .025), and cocamidopropyl betaine (P = .0007) were significantly increased in children with AD compared to those without AD. LIMITATIONS: Technical variation between providers and potential for misclassification, selection, and recall biases. CONCLUSION: Children with AD are significantly more likely to have PPT reactions and should be referred for evaluation of allergic contact dermatitis and obtain patch testing.

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.

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.

Congenital Cutaneous Candidiasis in Preterm Infants.

Congenital cutaneous candidiasis (CCC) is a rare condition, which typically affects premature and very low birthweight neonates. Affected infants present with a diffuse rash of variable morphology, which can appear as peeling, sloughing desquamation; maculopapular lesions; or, less commonly, pustules, vesicles, or bullae. Due to the varied nature of the clinical presentation, the diagnosis of CCC can be quite difficult but critically important because early treatment with intravenous fluconazole can prevent disease progression. In this review, we summarize the epidemiology, pathogenesis, clinical presentation, evaluation, and management of CCC.

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.

Congenital erosive and vesicular dermatosis healing with reticulated and supple scarring: Two cases secondary to fungal infection.

Congenital erosive and vesicular dermatosis (CEVD) is a rare skin condition that most commonly presents as erosive and vesicular lesions on the trunk and extremities in premature infants and heals with characteristic reticulated and supple scarring (RSS). The exact pathogenesis of CEVD is unknown and is typically a diagnosis of exclusion. We present the cases of two extremely premature neonates with Candida septicemia who were found to have diffuse, erythematous skin eruptions shortly after birth that ultimately healed with RSS. Through these cases, we highlight the importance of including fungal infection in the work-up of CEVD healing with RSS.

Pathologic acne in pre-pubertal children: A case series and review on when to refer to pediatric endocrinology.

Acne vulgaris is an extremely common chronic disease of the pilosebaceous unit. Despite its ubiquity, acne in the childhood years of approximately ages 1-6 years is exceedingly rare. Physicians should be suspicious of underlying systemic disease processes in patients of this age who present with onset of acne lesions, as pre-pubertal acne in childhood has a distinctly different pathology than that of other age groups. Through a case series, we highlight the importance of a thorough work-up and provide a review on when to refer to pediatric endocrinology to rule out precocious puberty and tumors as the cause of pre-pubertal acne.

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.

Feeding Performance and Outcomes in Infants With Robin Sequence Undergoing Mandibular Distraction Osteogenesis.

To describe perioperative feeding performance in infants with Robin sequence (RS) who underwent mandibular distraction osteogenesis (MDO).A retrospective study of infants that underwent MDO from May 2010 to December 2019.Tertiary pediatric hospital.A total of 40 patients underwent MDO and 20 met inclusion criteria. Of the included infants, 6 had an associated syndrome and 80% were male.Time to full oral feeds, rate of G-tube placement, and change in weight percentile following MDO.Average oral intake prior to MDO was 22.1% of individual goal feeds. Among the 15 (75%) children that did not require G-tube placement, mean time to full oral feeds after MDO was 11 days ± 5.7 days, with 80% of infants reaching full oral feeds within 2 weeks after extubation. The proportion of G-tube placement in patients with a syndrome was higher than in isolated RS (-0.6; 95% CI: -1.0, -0.2). Mean percentages of weight-for-age percentile decreased during the first 3 months after the procedure. This was followed by a mean upturn in weight starting after the third month after MDO with a recovery to preoperative mean weight-for-age percentiles by 6 months after surgery.This study suggests that infants with RS may achieve full oral feeds despite poor feeding performance before MDO. Infants with syndromic RS are more likely to require G-tube. These findings may be used to inform G-tube discussion and offer a timeline to work toward goal oral feeds for infants with RS after MDO.
