RESUMEN
Sweet's syndrome (acute febrile neutrophilic dermatosis) is an uncommon inflammatory condition most often associated with painful skin lesions of the head, neck, and upper extremities. To the authors' knowledge, this case report is the only published record of the necrotizing clinical variant of Sweet's syndrome in the periorbital space. This case follows a 91-year-old female who presented with generalized cutaneous eruptions of tender erythematous plaques, including a necrotic plaque of the left upper eyelid, and pancytopenia. A biopsy of an inner thigh lesion was consistent with Sweet's syndrome. Initially diagnosed with preseptal cellulitis, the patient experienced marked clinical improvement with corticosteroids. This, coupled with the histopathologic findings of her thigh biopsy and the absence of eyelid margins, led to the diagnosis of periorbital necrotizing Sweet's syndrome. Although cases of Sweet's syndrome in the periorbital region are rare, these diagnoses should not be overlooked and may be critical to patient care.

Face mask-wearing practices and their impact on the visual field bear particular importance in the coronavirus disease 2019 (COVID-19) pandemic era. This case series examines 10 participants with no history of ocular impairment or visual field defects who underwent age-corrected visual field testing in both eyes with different types of face masks. Wearing duckbill N95 masks was consistently associated with increased accuracy errors in the inferior altitudinal visual field when compared to wearing surgical masks or no masks. These findings support public health guidance that has previously attributed the risks of falls and accidents to face mask wearing.

BACKGROUND: Upper eyelid ptosis after cosmetic botulinum toxin is generally considered short-lived and responsive to apraclonidine ophthalmic drops. The authors present a series with persistent ptosis. OBJECTIVE: To report a series of patients with persistent upper eyelid ptosis after cosmetic botulinum toxin. MATERIALS AND METHODS: A retrospective case review series of 7 patients referred for management after developing visually significant upper eyelid ptosis after cosmetic botulinum toxin type A treatment. RESULTS: Patients in this series experienced persistent visually significant ptosis after cosmetic botulinum toxin lasting from 6 weeks to 13 months. Six of the 7 patients were treated with apraclonidine ophthalmic solution. Apraclonidine drops appeared to be clinically effective within 4 to 6 weeks of the resolution of ptosis. CONCLUSION: Upper eyelid ptosis after cosmetic botulinum toxin can persist for many months after treatment. Based on this series, the authors propose that apraclonidine drops can be used at the time of initial assessment to predict the relative longevity of ptosis after cosmetic botulinum toxin treatment (Level 4 evidence recommendation). After a 1-week trial, responders can be advised that ptosis is likely to resolve in 4 to 6 weeks. Nonresponders should be counseled that resolution may take longer than 6 weeks.

PURPOSE: To perform a quantitative analysis of adipocyte viability after fat processing during autologous fat transfer, comparing the processing methods of washing, centrifuging, and sedimentation. METHODS: An experimental study was conducted in which 24 fat samples were obtained after processing from 22 patients undergoing autologous fat transfer. Histologic analysis of periodic acid-Schiff-stained specimens was then performed. RESULTS: Cell counts per high-powered field of intact adipocytes and nucleated adipocytes and adipocyte cross-sectional area were significantly greater in samples processed by sedimentation, compared with those by centrifuging or washing. CONCLUSIONS: Of the various processing techniques currently used during autologous fat transfer, sedimentation appears to yield a higher proportion of viable adipocytes than does washing or centrifuging.
