ABSTRACT
BACKGROUND: Acute pseudoperniosis (PP) has a recognized association with COVID-19 and tends to occur without cold precipitation in young, healthy patients, often without a clear history of COVID-19. These lesions usually resolve within 2 weeks and without long-term sequelae. In the early months of 2021, patients with delayed and protracted PP began to emerge. We have called this presentation 'tardive COVID-19 PP (TCPP)'. AIM: To consolidate and expand knowledge on TCPP, we describe the clinical characteristics, treatments and outcomes of 16 patients with TCPP who were reviewed by our outpatient dermatology service. RESULTS: The initial clinical manifestations were erythema, swelling and PP of the fingers in 56.2%, and of the toes in 31.2%, desquamation in 56.2% and acrocyanosis in 12.5%. Ten patients had eventual involvement of all acral sites. The median duration of symptoms was 191 days. Six patients reported close contact with a confirmed or suspected case of COVID-19, but only two had positive COVID-19 tests. Four patients experienced complete or almost complete resolution of symptoms, while the rest remain under active treatment. CONCLUSION: Unlike acute PP, TCPP has a protracted and delayed presentation that is typically associated with profound acrocyanosis. Patients with TCPP represent a new phenomenon that is part of the post-COVID-19 syndrome, with risk factors and pathophysiology that are not yet fully understood. Our data indicate that likely predisposing factors for developing TCPP include young age, a preceding history of cold intolerance and an arachnodactyloid phenotype. Anorexia, connective tissue disorders or sickle cell trait may also predispose to TCPP. In addition, low titre antinuclear antibody positivity, the presence of cryoglobulins, or low complement levels may represent further risk factors. Finally, prolonged low temperatures are also likely to be contributing to the symptoms.

AIM: To evaluate the efficacy and safety of the uterine artery embolisation (UAE) in combination with methotrexate (MTX) for conservative management of placental adhesive disorders. MATERIAL AND METHODS: Patients with placental adhesive disorders (including accreta, increta, and percreta lesions) that were treated with UAE in combination with MTX were identified and were followed prospectively for outcomes including uterine preservation and complications. RESULTS: Twenty-six patients were identified who had the diagnosis of abnormal placenta implantation during this study. Fourteen patients were excluded because they were treated by a caesarean hysterectomy. Among remaining 12 patients, the successful uterine preservation observed in seven (58%) cases. Menstruation cycles returned in all successfully treated patients, although they did not have desire to get pregnant. Five (42%) patients underwent primary or delayed hysterectomy due to severe post-partum haemorrhage in three cases, and intestinal adhesion/peritonitis and secondary post-partum haemorrhage/sepsis in two patients, respectively. CONCLUSION: Although this interventional method is relatively successful in uterine preservation, the possibility of treatment failure cannot be ignored. Given that there are too few data regarding its efficacy and safety, this method should be reserved to patients who have a strong desire to maintain the uterus and their fertility, or if it is technically difficult to perform hysterectomy due to the extent of the invasion.
