Clinical outcomes of the light adjustable lens in eyes with a history of prior corneal refractive surgery.

PURPOSE: This study aimed to evaluate the visual and refractive outcomes in eyes with a history of laser corneal refractive surgery implanted with the second-generation light-adjustable lens (LAL). SETTING: Private Practice, Sioux Falls, South Dakota, US. DESIGN: Retrospective, consecutive case series. METHODS: Eyes with a history of prior corneal refractive surgery that underwent cataract surgery with implantation of the LAL and were targeted for plano were included. Data on the type and number of prior refractive surgeries were collected, in addition to the timing and number of postoperative adjustments. The primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and the percentage (%) of eyes within ±0.25 diopter (D), ±0.50D, and ±1.00 D of their refractive target. RESULTS: 76 eyes from 70 patients were included. A total of 45 eyes with a history of one prior refractive surgery and 31 eyes with a history of ≥2 refractive surgeries were included. 74% (n=56) of all eyes achieved UDVA of 20/20 or better, 88% (n=67) achieved 20/25 UDVA or better and 93% (n=71) were correctable to 20/20 or better postoperatively. For refractive outcomes, 66% of eyes (n=50) were within ±0.25 D and 86% (n=65) were within ±0.50 D of refractive target. CONCLUSIONS: Patients with a history of laser corneal refractive surgery achieved favorable visual and refractive outcomes with the LAL. This intraocular lens (IOL), which affords postoperative adjustability, is a promising option for patients with a history of corneal refractive surgery who maintain high expectations for functional uncorrected acuity following cataract surgery.

A Retrospective Cohort Study to Evaluate a Swallow Study Use in the NICU Population to Optimize Feeding Support.

INTRODUCTION: Premature neonates demonstrate difficulties with swallowing due to neurological immaturity as well as a weaker suck reflex compared to full term infants. Swallowing starts to mature by 33-34 weeks of gestational age. In neonates, dysphagia is evaluated clinically by speech-language pathologists and a swallow study is ordered for infants with swallowing difficulties. However, leaving the NICU to undergo a swallow study puts infants under environmental stressors and a swallow study exposes infants to radiation. There is a concern that swallow studies are being over-utilized in the NICU. METHODS: All premature infants born before 36 weeks GA admitted to the Sanford Boekelheide NICU between January 2015 and December 2019 who underwent a swallow study were enrolled in data analysis. Deidentified data was collected retrospectively through electronic medical record review and RedCap was utilized for data storage. Infants were divided in two cohorts; those who underwent a feeding change (feeding thickening) following a swallow study vs those who continued with prior feedings. Infant demographics and characteristics were assessed to identify a group of infants who are at high risk of aspiration. RESULTS: A total of 179 infants were identified. DISCUSSION: A swallow study can identify infants at high risk for aspiration, however, many could potentially be avoided by allowing more time for infant maturation.

Guselkumab-Associated Pulmonary Disease and Diffuse Alveolar Hemorrhage with Drug Rash with Eosinophilia and Systemic Symptoms.

Psoriasis is a common skin condition worldwide. Moderate-to-severe disease is treated with biologic or non-biologic disease-modifying anti-rheumatic drugs. These include tumor necrosis factor (TNF)-a inhibitors, interleukin (IL)-17 inhibitors, and IL-23 inhibitors. Case reports of inhibitors of TNF-a and IL-12p40 subunits causing interstitial pneumonia (IP) have been published in the literature, but no case of anti-IL-23p19 subunit biologics causing IP and acute respiratory distress syndrome (ARDS) has been reported before. We report a case of a patient with restrictive lung disease secondary to a body mass index of 36.54 kg/m2, obstructive sleep apnea, and psoriasis, who developed IP and ARDS presumed to be secondary to guselkumab, an anti-IL-23p19 subunit monoclonal antibody. He was on ustekinumab, an anti-IL-12/23p40 for the treatment of psoriasis, but was switched to guselkumab eight months before the presentation, and since then he had been complaining of progressive shortness of breath. He initially presented to the hospital after having drug reaction with eosinophilia and systemic symptoms (DRESS) after being started on amoxicillin for a tooth infection. He was treated with high-dose intravenous steroids but developed progressive shortness of breath. Broad-spectrum antibiotics were added. An extensive infectious, autoimmune, and hypersensitivity work-up was undertaken, which returned negative. A bronchoscopy with bronchoalveolar lavage was performed, which revealed diffuse alveolar hemorrhage (DAH). His lung imaging and oxygenation progressively got worse; hence, no lung biopsy was taken. He was intubated and required inhaled nitric oxide, but due to the lack of improvement, the family elected for comfort measures, and the patient was extubated and passed away. To our knowledge, this is the first case of an association between guselkumab, IP, ARDS, and DAH. Rare instances of DAH with DRESS have been reported before. Whether it was DRESS or guselkumab that caused DAH was uncertain in our patient. Clinicians should monitor for DAH and shortness of breath in patients on guselkumab so that more data can be obtained and studied in the future.
