Erythrodermic psoriasis is characterized by diffuse erythema and scaling that can affect total body surface area and cause sepsis and death without treatment. 1 Vaccination has been associated with both guttate and plaque psoriasis flare-ups. 2 To date, we have not found a documented case of erythrodermic psoriasis flare due to the SARS-CoV-2 vaccine. Here, we report the observation of an erythrodermic psoriasis eruption in an adult patient who received the first dose of the Pfizer-BioNTech SARS-CoV-2 vaccine. F I G U R E 1 Initial presentation 6 days after onset of rash and 7 days after the initial dose of SARS-CoV-2 vaccine. (A) Confluent plaques on the torso and arms. (B) Confluent plaques on the back. (C) Annular erythematous plaques with some coalescing into confluent plaques with hyperkeratotic scales on the lower extremities with partial sparing of the medial thighs and sparing of the feet

Introduction Despite the presence of clinical practice guidelines for overnight admission of pediatric patients following adenotonsillectomy, variance in practice patterns exists between pediatric otolaryngologists. The purpose of this study is to examine severity of apnea–hypopnea index (AHI) as an independent predictor of postoperative respiratory complications in children undergoing adenotonsillectomy. Methods Retrospective chart review of all children undergoing adenotonsillectomy at a large tertiary referral center between January 2015 and December 2019 who underwent preoperative polysomnography and were admitted for overnight observation. Charts were reviewed for total adverse events and respiratory events occurring during admission. Results Overall, respiratory events were seen in 50.6% of patients with AHI ≥10 and in 39.6% of patients with AHI <10. The overall mean AHI was 19.2, with a mean of 28.1 in the AHI ≥10 subgroup vs 4.6 in the AHI <10 subgroup. There was no statistical correlation or increased risk between an AHI ≥10 and having a pure respiratory event, with a relative risk of 1.19 (.77–1.83, P = .43). There was a statistically significant difference between the mean AHI of those with any adverse event and those without (21.6 vs 13.4, P = .008). There is additionally an increased risk of any event with an AHI over 10, with a relative risk of 1.51 (1.22–1.88, P < .0001). Conclusion Preoperative AHI of 10 events per hour was not a predictor of postoperative respiratory complications. However, there was a trend for those with a higher AHI requiring additional supportive measures or a prolonged stay. Practitioners should always use their best judgment in deciding whether a child warrants postoperative admission following adenotonsillectomy.
