Serious Adverse Events With Injectable Fillers: Retrospective Analysis of 7,659 Patient Outcomes.

BACKGROUND: In total, 2.7 million injectable filler treatments were performed in 2019 in the United States. Although generally considered to be a safe treatment modality, adverse events may occur in rare situations. OBJECTIVE: Analyze serious adverse events from injectable filler treatments, including infections, cutaneous necrosis, blindness, or delayed-onset nodule formation, spanning 11 years for 3 board-certified dermatologists and review their incidence, management, and outcomes. MATERIALS AND METHODS: A retrospective analysis was performed of injectable filler treatments spanning 11 years at a multipractitioner outpatient clinic. Serious adverse events were identified, and treatment measures were documented. A literature search was performed to determine recent trends and outcomes for comparison. RESULTS: Between January 2009 and August 2020, 18,013 mL of injectable filler was administered to 7,659 patients. Of the 18,013 mL administered, 74.1% comprised hyaluronic acid derivatives, 19.19% poly-l-lactic acid, and 6.71% calcium hydroxylapatite. Four serious adverse events were identified. Three events were delayed-onset skin nodule formation. One adverse event was related to vascular compromise and subsequent cutaneous necrosis. After appropriate treatment, all adverse events resolved without significant long-term sequelae. CONCLUSION: Serious adverse events associated with injectable fillers, when performed by board-certified dermatologists, are extremely rare and can be successfully managed with appropriate treatment.

Frequency, reasons, and risk factors of entacapone discontinuation in Parkinson disease.

OBJECTIVES: To determine the rate of and identify reasons for discontinuation of entacapone treatment in Parkinson disease patients. METHODS: A retrospective study design was used, including medical record reviews and telephone call to the patient as needed. RESULTS: Two hundred and twenty-two Parkinson disease patients were started on entacapone over a period of 3 years. One hundred and twenty-two patients (56%) had discontinued the medication by the end of the follow up period. Reasons for discontinuation included lack of efficacy (46%), worsening of parkinsonian symptoms (28%), worsened cognition (20%), dyskinesia (17%), nausea (11%), diarrhea (9%), cost (4%), other side effect (8%), and other, non-medication related reasons (19%). Presence of wearing off at the time of initial treatment and male sex were associated with decreased dropout rates, while the presence of orthostatic hypotension increased the likelihood of discontinuation. Patient age, disease duration, Hoehn and Yahr stage, Unified Parkinson's Disease Rating Scale section II score, presence of dementia, hallucinations, dyskinesias, or depression, number of daily L-dopa doses, and concomitant treatment with dopamine agonists did not affect dropout rate. CONCLUSIONS: Lack of efficacy seems to be the main reason for entacapone discontinuation. Male patients with wearing off and no orthostatic hypotension seem to tolerate the medication better. Advanced disease stage, presence of cognitive dysfunction, and presence of dyskinesia should not necessarily preclude patients from being treated with entacapone, when otherwise indicated.
