Utility of routine patch testing prior to surgical repair of pectus excavatum: A multidisciplinary experience via retrospective review at a single tertiary care center.

BACKGROUND: The Nuss procedure is the only implant procedure in which routine, rather than selective, preoperative patch testing is recommended. This practice has recently been called into question. OBJECTIVE: To evaluate an updated experience of pre-implant patch testing in patients undergoing the Nuss procedure. METHODS: A retrospective chart review of Nuss procedures from 2012 through 2020. RESULTS: Forty-five patients were identified for data collection. From 2012 to 2014, none of the 14 patients were patch tested. From 2015 to 2020, 26 of 31 (83.9%) were patch tested. Of those tested, only 2 had a positive patch test. A hypoallergenic titanium bar was inserted in each case. In total, there were zero bar reactions. CONCLUSION: The risks of patch testing are extremely small and should be weighed against the serious implications of even one bar allergy when deciding on future guidelines.

Localized bullous pemphigoid after knee replacement surgery.

Bullous pemphigoid (BP) most commonly presents as widespread, itchy, tense blisters in older patients. Localized bullous pemphigoid is a less common form of BP that can be more difficult to diagnose because of its similarity to more common conditions such as allergic contact dermatitis or bullous cellulitis. Prompt recognition of localized BP is important so that appropriate treatment can be started. We present a 57-year-old woman who presented with pruritic tense bullae overlying the surgical scar from a knee replacement 6 months prior on her anterior right knee. This case illustrates the potential for localized BP to be triggered by surgical procedures.

Implementation and Impact of a Store-and-Forward Teledermatology Platform in an Urban Academic Safety-Net Health Care System.

Background:Minority and low-income patients disproportionately experience dermatologic access challenges. Store-and-forward (SAF) teledermatology has emerged as a model of care delivery that may improve access. We sought to evaluate patterns of utilization and overall impact after SAF teledermatology implementation in a safety-net health care system. Methods:We performed a retrospective review of 3,285 teledermatology consultations from 2014 to 2017 in an urban academic safety-net health care system. Results:A total of 1,680 (51.2%) patients were referred for inflammatory/rash conditions and 967 (29.5%) for skin lesions. The teledermatologist recommended in-person evaluation in 1,199 encounters (36.5%). Median wait time for a subsequent appointment was 36 days (range 0-244 days). Of subsequent in-clinic visits, 237 patients (26.4%) underwent skin biopsy. No-show rate after referral was 11.8%. In comparison, median wait time for dermatology appointment through standard referral was 64 days, with a no-show rate of 18.6%. Biopsy rate of patients referred via teledermatology was 26.4%, in comparison to a rate of 10.9% of patients referred directly from primary care provider. Discussion:Implementation of SAF teledermatology in a safety-net health system resulted in avoidance of 63.5% potential dermatology visits. Consultation typically resulted in a change in suspected diagnosis or management plan. Rates of concordance between teledermatology consults and in-person evaluations were high. Median wait time was reduced by almost half, no-show rate was reduced ∼37%, and biopsy rate was more than double for teledermatology patients compared with standard referral. Conclusion:These findings suggest that SAF teledermatology may improve access to high-quality dermatologic care and increase clinic efficiencies for patients in safety-net health care systems.

Lichen planus pigmentosus in a blaschkoid distribution.

Lichen planus pigmentosus is a pigmentary disorder of unknown etiology, with diffuse hyperpigmentation of sun-exposed areas, more commonly seen in some ethnic and racial groups. We report an unusual case of lichen planus pigmentosus in a 40-year-old man with Fizpatrick type III skin that was present in a blaschkoid distribution on the trunk, a distribution that has been rarely reported. This unique presentation of lichen planus pigmentosus may contribute to better understanding of the etiology, as the blaschkoid distribution may reflect underlying cutaneous mosaicism that renders those cells more susceptible to an insult that results in lichen planus pigmentosus. This disorder should be considered in the differential diagnosis of macular hyperpigmentation, especially in those from more commonly affected ethnic and racial groups, even when the distribution is atypical and in the absence of history of sun exposure.

Menkes Disease Mimicking Child Abuse.

Althouygh Menkes disease has well-recognized neurologic, developmental, and cutaneous features, the initial presentation may resemble child abuse. We describe a 5-month-old boy with multiple fractures indicative of nonaccidental trauma who was ultimately diagnosed with Menkes disease. Copper deficiency leads to connective tissue abnormalities and may result in subdural hematomas, wormian bones, cervical spine defects, rib fractures, and spurring of the long bone metaphyses. Several of these findings, including fractures and subdural hematomas, may be misinterpreted as child abuse.

Uveitis and Systemic Inflammatory Markers in Convalescent Phase of Ebola Virus Disease.

We report a case of probable Zaire Ebola virus-related ophthalmologic complications in a physician from the United States who contracted Ebola virus disease in Liberia. Uveitis, immune activation, and nonspecific increase in antibody titers developed during convalescence. This case highlights immune phenomena that could complicate management of Ebola virus disease-related uveitis during convalescence.

Retinoschisis and outer retinal hole formation in a patient with papillorenal syndrome.

This report describes a 19-year-old patient with the rare association of macular retinoschisis and outer retinal hole formation with papillorenal syndrome. Initially diagnosed with transplant-related central serous chorioretinopathy, she presented several years later with worsening vision and distortion in her right eye. On examination, she was found to have bilateral optic nerve dysplasia, bilateral macular and extramacular retinoschisis, and a serous retinal detachment with outer hole formation in the right eye. A history of prior renal transplantation due to poor kidney development led to the diagnosis of papillorenal syndrome.
