RESUMO
Nephrogenic calciphylaxis is associated with multiple risk factors including long-term dialysis dependence, hyperphosphatemia, hypercalcemia, parathyroid hormone derangements, vitamin K deficiency, obesity, diabetes mellitus, warfarin use, and female sex. Bariatric surgery is known to cause altered absorption, leading to mineral and hormonal abnormalities in addition to nutritional deficiency. Prior case reports on calciphylaxis development following bariatric surgery have been published, though are limited in number. We report a case series of five bariatric patients from a single institution who developed nephrogenic calciphylaxis between 2012 and 2018. These patients had a history of bariatric surgery, and at the time of calciphylaxis diagnosis, demonstrated laboratory abnormalities associated with surgery including hypercalcemia (n = 3), hyperparathyroidism (n = 2), hypoalbuminemia (n = 5), and vitamin D deficiency (n = 5), in addition to other medication exposures such as vitamin D supplementation (n = 2), calcium supplementation (n = 4), warfarin (n = 2), and intravenous iron (n = 1). Despite the multifactorial etiology of calciphylaxis and the many risk factors present in the subjects of this case series, we submit that bariatric surgery represents an additional potential risk factor for calciphylaxis directly stemming from the adverse impact of malabsorption and overuse of therapeutic supplementation. We draw attention to this phenomenon to encourage early consideration of calciphylaxis in the differential for painful skin lesions arising after bariatric surgery as swift intervention is essential for these high-risk patients.

BACKGROUND: Calciphylaxis is a thrombotic vasculopathy characterized by painful necrotic ulcerations. There are no Food and Drug Administration approved therapies despite high mortality. OBJECTIVE: To compare mortality and wound healing outcomes in patients treated with hyperbaric oxygen therapy (HBOT) in addition to intravenous sodium thiosulfate (IV STS) versus patients who received IV STS only. Findings were stratified by dialysis status and modality. METHODS: 93 patients were included, with 57 patients in the control group (IV STS) and 36 patients in the treatment group (HBOT + IV STS). Mortality data were analyzed with traditional survival analyses and Cox proportional hazard models. Longitudinal wound outcomes were analyzed with mixed effects modeling. RESULTS: Univariate survival analyses showed that full HBOT treatment was associated with significantly (P = .016) longer survival time. Increasing number of HBOT sessions was associated with improved mortality outcomes, with 1, 5, 10 and 20 sessions yielding decreasing hazard ratios. There was also a significant (P = .042) positive association between increasing number of HBOT sessions and increased wound score. LIMITATIONS: Data collection was retrospective. CONCLUSION: HBOT may have a role in the treatment of calciphylaxis with benefits demonstrated in both mortality and wound healing. Larger prospective studies are needed to identify which patients would most benefit from this intervention.

OBJECTIVE: To assess cellulitis in the neonatal intensive care unit (NICU) setting and identify risk factors for its disease severity and whether cellulitis influences length of stay (LOS). STUDY DESIGN: In this retrospective study, patients with cellulitis were identified using the electronic health record while admitted to the NICU at Massachusetts General for Children from January 2007 to December 2020. Demographic and clinical data were extracted from patient records. Two multivariable logistic regression models were constructed to assess for independent predictors for increased LOS (≥30 days) and complicated cellulitis in the hospital. RESULTS: Eighty-four patients met the study criteria; 46.4% were older than 14 days at the time of diagnosis of cellulitis, 61.9% were non-White, and 83.3% were born prematurely; 48.8% had complicated cellulitis as defined by overlying hardware (41.7%), sepsis (7.1%), requirement for broadened antibiotic coverage (7.1%), bacteremia (4.8%), and/or abscess (3.6%). The mean hospital LOS was 58.5 ± 36.1 days SD, with 72.6% having a LOS greater than 30 days. Independent predictors of increased LOS were extreme prematurity (<28 weeks' gestation) (OR: 14.7, P = .03), non-White race (OR: 5.7, P = .03), and complicated cellulitis (OR: 6.4, P = .03). No significant predictors of complicated cellulitis were identified. CONCLUSIONS: This study identifies complicated cellulitis in the NICU as an independent predictor of increased hospital LOS in neonates. Implementation of strategies to mitigate the development of cellulitis may decrease LOS among this high-risk population.

Isotretinoin is a systemic therapy approved for acne and has historically required lab monitoring in addition to adherence to the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) given the medication's teratogenic effects. The COVID-19 pandemic resulted in the expansion of telemedicine, acceptance of remote pregnancy tests, and relaxation of lab monitoring practices. A retrospective review of 142 pediatric patients was conducted, and multivariate linear regression was performed to examine differences in prescribing patterns pre-COVID and during COVID. Backward elimination identified gender and the interaction between acne severity and number of systemic treatments tried before isotretinoin as significant factors associated with increased number of visits to isotretinoin initiation, with females requiring more visits before starting isotretinoin at every acne severity level and even after accounting for systemic treatments previously tried. While the changes catalyzed by the pandemic may have improved visit-related burdens for patients and caregivers, female patients with acne continue to be delayed in receiving isotretinoin even when adjusting for acne severity and systemic treatments trialed, underscoring persistent gender disparities in prescribing practices for isotretinoin.

The emergency department (ED) is a frequent source of care for pediatric patients with dermatologic conditions, possibly owing to limited access to routine and urgent outpatient dermatology appointments. The demographics, clinical characteristics, follow-up scheduling practices, and attendance rates of 50 pediatric and 142 adult patients evaluated by the dermatology consult service in the ED were reviewed. High rates of follow-up attendance were observed in the pediatric and adult populations, with the majority receiving an appointment within 2 weeks. The dermatology consult service may play an important role in facilitating post-discharge access to outpatient care.

The clinical features of 588 pediatric inpatients admitted with a diagnosis of cellulitis were reviewed with attention to diagnostic accuracy of true cellulitis (95.1%) versus pseudocellulitis (4.9%) and utilization of specialist consultations (28.1% infectious disease, 6.1% dermatology). Laboratory abnormalities were unable to distinguish cellulitis from pseudocellulitis, supporting previous studies that routine laboratory evaluation may be unnecessary for this diagnosis. Higher rates of pseudocellulitis were identified in cases involving specialist consultation by both dermatology (44.8% pseudocellulitis, 4.1% true cellulitis, p < .001) and infectious disease (48.3% pseudocellulitis, 27.0% true cellulitis, p = .01). Thus, consultation may improve the diagnostic accuracy of suspected cellulitis among pediatric inpatients.
