Exposure to persistent hemodynamically significant patent ductus arteriosus is associated with retinopathy of prematurity.

BACKGROUND: Hemodynamically significant patent ductus arteriosus (hsPDA) shunt may predispose infants to retinopathy of prematurity (ROP) because of its higher preductal cardiac output and blood oxygen content, which may augment ocular oxygen delivery. METHODS: A retrospective cohort study of preterm infants, born at <27 weeks' gestation and admitted at <24h postnatal age to a large quaternary referral was conducted. The primary composite outcome was death at <32 weeks or moderate-to-severe ROP (≥stage 2 or requiring treatment) in either eye. Secondary outcomes included ROP requiring treatment, and any ROP. Univariate analysis of patient characteristics and outcomes was performed as well as logistic regression. A receiver operating characteristics curve was generated for the outcome of ROP ≥stage 2 or requiring treatment. RESULTS: A total of 91 patients were screened, of whom 86 (54 hsPDA, 32 controls) were eligible for inclusion. hsPDA patients were younger and lighter at birth and had a higher burden of hyperglycemia and respiratory illness. The rates of the composite outcome (death <32 weeks or moderate-to-severe ROP) and of any ROP were more frequent in the hsPDA group. hsPDA shunt exposure was independently associated with development of any ROP among survivors to assessment (P = 0.006). PDA cumulative exposure score of 78 (clinical equivalent = 7 days high-volume shunt exposure) predicts moderate-to-severe ROP with 80% sensitivity and 78% specificity. CONCLUSIONS: Among infants <27 weeks, hsPDA shunt is associated with increased risks of a composite outcome of death or moderate-to-severe ROP, as well as ROP of any stage. Shunt modulation as a strategy to reduce ROP represents a biologically plausible avenue for investigation.

Unexpected Hepatic Manifestations of Rheumatoid Arthritis.

Rheumatoid arthritis is an inflammatory condition typically affecting joint spaces. However, extra-articular manifestations are common including vascular and gastrointestinal tract involvement. This disease may also manifest as nodules, although these are typically found in the extremities and are very rarely seen in the liver. When a patient presents with liver nodules, an extensive work-up is typically completed to determine infectious, inflammatory, or malignant etiologies. We report hepatic findings of rheumatoid arthritis during an extensive inpatient investigation of liver lesions.

Severe Lupus Enteritis Complicated by Intractable Gastrointestinal Hemorrhage.

Lupus enteritis (LE) is a rare presentation of systemic lupus erythematosus manifesting with nonspecific symptoms, laboratory derangements, and imaging findings. Rarely, LE may progress to bowel perforation, hemorrhage, and even death. Treatment with systemic glucocorticoids often results in rapid clinical improvement, but patients may require further immunosuppression. We present a case of severe LE complicated by life-threatening intractable gastrointestinal hemorrhage and warm autoimmune hemolytic anemia refractory to glucocorticoids and ultimately requiring massive transfusions, intravenous immunoglobulin, and plasmapheresis. This case illustrates the importance of early specialist involvement and treatment with intravenous immunoglobulin and plasmapheresis for severe, life-threatening LE.

Dementia: Helping Caregivers and Family Members Cope.

Physicians who care for patients with dementia also must provide support for patient caregivers and family members. Caregiver burden requires attention from the health care team because most caregivers of patients with dementia report high levels of emotional stress. This burden is more severe when patients have comorbid conditions, behavioral and psychological symptoms of dementia, and more severe functional impairments. A functional assessment of activities of daily living can be done using standardized screening tools. Driving is a specific instrumental activity of daily living that can become dangerous in dementia; decisions about stopping driving often are complicated by patient resistance and loss of independence. Clinicians will be faced with questions regarding patient decision-making capacity, which is the ability to comprehend information and use reason to communicate an informed choice. As complex decision-making capacity is likely to diminish with dementia progression, discussing advance directives and designation of a surrogate decision-maker early in the disease course is paramount. Dementia remains an incurable progressive disease; therefore, management often is directed toward maintaining quality of life, managing symptoms, and palliating suffering. Patients with dementia may become eligible for hospice when they lose speech, locomotion, or consciousness.

Ischemic Stroke Management: Posthospitalization and Transition of Care.

Ischemic stroke is a major cause of morbidity and mortality worldwide. Ischemic stroke and transient ischemic attack exist on a continuum of the same disease process. Ischemic stroke is common, and more than 85% of stroke risk is attributed to modifiable risk factors. The initial management of acute stroke is usually performed in the emergency department and hospital settings. Family physicians have a key role in follow-up, ensuring that a complete diagnostic evaluation has been performed, addressing modifiable risk factors, facilitating rehabilitation, and managing chronic sequelae. Secondary prevention of ischemic stroke includes optimization of chronic disease management (e.g., hypertension, type 2 diabetes mellitus, dyslipidemia), nonpharmacologic lifestyle interventions (e.g., diet changes, exercise, substance use counseling), and pharmacologic interventions. Dual antiplatelet therapy with aspirin and clopidogrel is generally indicated for minor noncardioembolic ischemic strokes and high-risk transient ischemic attacks and should be converted to single antiplatelet therapy after 21 to 90 days. Secondary prevention of cardioembolic stroke requires long-term anticoagulation. Direct oral anticoagulants are preferred over warfarin for patients with nonvalvular atrial fibrillation. Poststroke problems with mobility, balance, cognition, dysphagia, and depression are common. Rehabilitation involves a multidisciplinary, multimodal approach that includes physical therapy, speech therapy, and treatment of chronic pain and poststroke depression.

The Ocular Trauma Score Underestimates Visual Recovery for the Most Severe Open-Globe Injuries.

PURPOSE: To compare visual outcomes after open-globe injury (OGI) with those predicted by the Ocular Trauma Score (OTS), and to investigate the effect of treatment with pars plana vitrectomy (PPV). DESIGN: Retrospective cohort study. SUBJECTS: Patients presenting with OGI to an academic United States ophthalmology department from 2017 to 2020. METHODS: Best-corrected visual acuity (VA) measurements at the most recent follow-up were compared with final VA predicted by the OTS, based on preoperative injury characteristics. The most recently measured VA of patients treated with PPV during initial OGI repair (primary PPV group) was compared with patients treated with PPV after initial OGI repair (secondary PPV group) and patients never treated with PPV (No PPV group). MAIN OUTCOME MEASURES: Best-corrected VA in the injured eye at last follow-up; secondary outcome measures included the occurrence of vitreous hemorrhage at any time, occurrence of retinal detachment at any time, rates of additional surgery, and rates of enucleation. RESULTS: One-hundred and thirty-three subjects with OGI were identified and analyzed. The overall rate of PPV was 32%. Predictors of worse VA at last follow-up included older age (P = 0.047) and worse presenting VA (P < 0.001). Visual acuity outcomes for eyes in OTS categories 2 to 5 did not significantly differ from OTS predictions. However, eyes in OTS category 1 had a higher likelihood of last follow-up VA of light perception (LP) to hand motion (46% in the study cohort vs. 15% predicted by the OTS, P = 0.004) and a lower likelihood of no LP (33% vs. 74%, P < 0.001). The secondary PPV group had the worst VA at presentation among the 3 groups (P = 0.016), but VA at last follow-up did not significantly differ between the study groups (P = 0.338). CONCLUSIONS: The most severe OGIs (i.e., OTS category 1) had better visual outcomes than predicted by the published OTS expectations, and secondary PPV was associated with significant visual improvement despite poor prognostic predictions. Evaluation by a vitreoretinal surgeon should be considered for all patients with severe OGI, especially those in OTS category 1.

Xp11.3 microdeletion causing Norrie disease and X-linked Kabuki syndrome.

Purpose: To describe a novel case of Norrie disease and X-linked Kabuki syndrome caused by a microdeletion encompassing multiple genes on the X chromosome. Observations: A 3-day-old boy born at full term had bilateral retrolental fibrovascular plaques. Surgery with lensectomy and vitrectomy revealed bilateral, closed funnel retinal detachments consistent with a clinical diagnosis of Norrie disease. In addition, the baby had congenital heart defects, hearing loss, and dysmorphic facies. His mother carried a clinical diagnosis of Kabuki syndrome. Genetic testing of the baby revealed an Xp11.3 microdeletion that included the NDP and KDM6A genes, confirming the baby had both Norrie disease and X-linked Kabuki syndrome. The mother was found via ultrawide-field fluorescein angiography to have asymptomatic peripheral retinal vascular anomalies, consistent with NDP-associated familial exudative vitreoretinopathy (FEVR). Conclusions and importance: This is the first reported case of Norrie disease together with X-linked Kabuki syndrome. Contiguous gene deletions may explain some of the variable systemic involvement in Norrie disease.

Case Report of Acute Esophageal Necrosis (Gurvits Syndrome) in Vaccinated, COVID-19-Infected Patient.

Acute esophageal necrosis (AEN) is a rare endoscopic finding associated with ischemic compromise of the distal esophagus. This finding can be seen in critically ill patients with COVID-19 infection. We present a case of a COVID-19-vaccinated elderly male with multiple comorbidities and active COVID-19 pneumonia admitted to the intensive care unit with septic shock and acute hypoxemic respiratory failure. The patient developed melena, and esophagogastroduodenoscopy (EGD) was performed, which showed necrosis of the lower esophagus suggestive of AEN. AEN has been associated with high mortality and should be considered when evaluating upper gastrointestinal bleed in a critically ill patient. This case describes the first report of isolated AEN in a patient fully vaccinated against COVID-19 presenting with a severe complicated COVID-19 infection.

A comparative study of strabismus surgery with retained or removed scleral explant after retinal detachment surgery.

PURPOSE: To compare, in a larger study population, the outcomes of strabismus surgery in patients who either had the scleral explant (EX) retained or removed after surgery for retinal detachment. METHODS: A comparative retrospective study includes data from 2 centres. Surgical outcome, motor success, sensory success, the number of secondary operations for strabismus and complications were compared between the two groups. Motor success was defined as horizontal deviation of ≤6 prism diopters (PD) and vertical deviation of ≤6PD. Sensory success was defined as no diplopia without use of prism. RESULTS: Forty-seven patients were included in the study; 70% had retained the EX and 74% had vertical strabismus. Horizontally, the final alignment was equal between the 2 groups, 4 PD vs.5 PD in the EX removed group. The patients with retained EX were referred with a significant lower mean vertical deviation and had a significant lower post-operative mean vertical deviation of 2 PD vs. 3 PD in the EX-removed group. The rates of motor success (76% vs. 71%) and sensory success (79% vs. 93%) did not differ significantly between the EX-retained and EX-removed groups. No patients underwent more than 2 operations. Two complications occurred in the EX-retained group: a subconjunctival cyst and an exposed EX. In the EX-removed group, 2 patients with retinal re-detachment were found in the follow-up period. CONCLUSION: Good surgical outcomes including high motor and sensory success were obtained regardless of the presence of the EX. Retinal re-detachment was observed in two patients with previously removed EX.

Is YouTube a Useful Tool for Trainees in Pediatric Cataract Surgery?

PURPOSE: To determine the utility of surgical videos published on YouTube (Google) as resources for trainee education in pediatric ophthalmology, the authors assessed the surgical proficiency, patient care, and video quality displayed in the published YouTube content. METHODS: The 10 most highly viewed pediatric and congenital cataract procedural videos published within the past 10 years were independently reviewed by three separate board-certified, fellowship-trained, practicing pediatric ophthalmologists. Videos were assessed for surgical competency on a 5-point Likert scale in six key areas as outlined in the American Academy of Ophthalmology's congenital cataract surgery guidelines. The teaching quality of the videos was also subjectively assessed based on multiple measures. RESULTS: The mean overall score was 3.93 ± 0.94 (range: 2.67 to 4.67). Only one video failed to receive an overall score of greater than 3, indicating incompetent overall surgical performance. No other video failed to have a mean competent score for any single individual technique. One video demonstrated potential patient safety concerns. Eighty percent of videos had adequate or better picture quality. CONCLUSIONS: Of the 10 most popular pediatric cataract surgical videos published on YouTube, all but one displayed competent overall surgical technique. Although viewers must always be wary because unvetted and potentially harmful videos may be published on the platform at any time, if used correctly, surgical content published on YouTube can be a helpful tool for ophthalmologic trainees.

Elevated transaminases and hypoalbuminemia in Covid-19 are prognostic factors for disease severity.

Prognostic markers are needed to understand the disease course and severity in patients with Covid-19. There is evidence that Covid-19 causes gastrointestinal symptoms and abnormalities in liver enzymes. We aimed to determine if hepatobiliary laboratory data could predict disease severity in patients with Covid-19. In this retrospective, single institution, cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid-19, we found that elevations of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) and Alkaline Phosphatase (AP) at any time during hospital admission increased the odds of ICU admission by 5.12 (95% CI: 1.55-16.89; p = 0.007), 4.71 (95% CI: 1.51-14.69; p = 0.01) and 4.12 (95% CI: 1.21-14.06, p = 0.02), respectively. Hypoalbuminemia found at the time of admission to the hospital was associated with increased mortality (p = 0.02), hypotension (p = 0.03), and need for vasopressors (p = 0.02), intubation (p = 0.01) and hemodialysis (p = 0.002). Additionally, there was evidence of liver injury: AST was significantly elevated above baseline in patients admitted to the ICU (54.2 ± 15.70 U/L) relative to those who were not (9.2 ± 4.89 U/L; p = 0.01). Taken together, this study found that hypoalbuminemia and abnormalities in hepatobiliary laboratory data may be prognostic factors for disease severity in patients admitted to the hospital with Covid-19.

The Model for End-Stage Liver Disease-Sodium Score at Admission Is Prognostic of Covid-19 Disease Severity.

Covid-19 is a systemic viral respiratory illness that can cause gastrointestinal manifestations. There is evidence that Covid-19 can infect liver tissue and may cause transaminemia. A prognostic model is needed to aid clinicians in determining disease severity. The Model for End-Stage Liver Disease-Sodium (MELD-Na) score is a mortality assessment tool in liver transplant patients that has been found to be prognostic in other clinical situations. This study aimed to determine if the MELD-Na score was associated with disease severity in patients with Covid-19, as assessed by multiple clinical outcomes including death within 30 days of discharge and development of an acute kidney injury (AKI). This is a retrospective cohort study that analyzed patients admitted to a community academic hospital with the diagnosis of Covid-19. The 30-day MELD-Na score was found to be significantly higher in those who died (14.38 ± 6.92) relative to those who survived (9.68 ± 5.69; p = 0.03). Additionally, patients with a MELD-Na score greater than 10 were found to have higher risk of developing an AKI (odds ratio (OR) 3.31 (1.08, 10.17); p = 0.03), need for hemodialysis (OR 9.69 (1.74, 53.96); p = 0.007), require vasopressors (OR 4.55 (1.22, 16.99); p = 0.02), and have a longer hospital stay (OR 4.17 (1.05, 16.47); p = 0.03). The MELD-Na score may serve as a useful clinical scoring system for prognosis in patients admitted to the hospital with Covid-19.

Esophageal necrosis associated with sodium polystyrene sulfonate (Kayexalate) use.

Acute esophageal necrosis is a rare cause of gastrointestinal bleeding. Endoscopically, it appears as a circumferential black-appearing mucosa affecting almost universally the mid and distal esophagus. Risk factors include low flow states, malnutrition, alcoholism, and the presence of multiple comorbidities. Prolonged exposure to gastric secretions and direct contact with corrosive agents also induce mucosal ischemia. Sodium polystyrene sulfonate use has been associated with severe gastrointestinal adverse events, including increased risk of small bowel and colonic necrosis and perforation. In susceptible individuals, sodium polystyrene sulfonate can also induce esophageal ischemia and necrosis, as illustrated in this case.

Vision screening outcomes in children less than 3 years of age compared with children 3 years and older.

PURPOSE: To compare the rates of amblyopia and treatment outcomes in children 0-2 years to those of children aged 3-5 years referred from a well-established community-based photoscreening program. METHODS: The medical records of children who failed vision photoscreening through Iowa KidSight and were subsequently seen at the University of Iowa for a complete eye examination over a 13-year period were retrospectively reviewed. Outcome measures were the number of children obtaining normal vision, the age at which normal vision was attained, and the elapsed time from screening examination to first documentation of normal vision. RESULTS: Of 319 subjects, 67 (21%) were 0-2 years of age and 252 (79%) were at least 3 years of age at screening. Amblyopia was found in 19% of the younger group and 30% of the older group (P = 0.12). Follow-up time was similar between groups. At final follow-up, 8% of children in the younger group did not attain normal vision, compared with 40% in the older group (OR = 8.92; 95% CI, 1.65-92.95; P = 0.009). Normal vision was attained on average at 35 months of age in the younger group and 69 months in the older group (P < 0.0001). CONCLUSIONS: In our study cohort, children <3 years of age were found to have an equivalent rate of amblyopia compared with children ≥3 of age. Those screened between ages 0-2 years of age attained normal vision at a significantly younger age and were more likely to attain normal vision.

Context matters: Contrasting behavioral and residential risk factors for Lyme disease between high-incidence states in the Northeastern and Midwestern United States.

The dynamics of zoonotic vector-borne diseases are determined by a complex set of parameters including human behavior that may vary with socio-ecological contexts. Lyme disease is the most common vector-borne disease in the United States. The Northeast and upper Midwest are the regions most affected - two areas with differing levels of urbanization and differing sociocultural settings. The probability of being infected with Lyme disease is related to the risk of encounters with Ixodes scapularis ticks infected with Borrelia burgdorferi sensu lato, which reflects both the environmental tick hazard and human behaviors. Herein, we compare behavioral and peridomestic risk factors perceived to influence the risk for human-tick encounters between two high-incidence states in the Northeast (New York and New Jersey) and one high-incidence state in the Midwest (Wisconsin). We used a smartphone application, The Tick App, as a novel survey tool, during spring and summer of 2018. Adaptive human behavior was identified in the relationship between outdoor activities and the use of methods to prevent tick bites. More frequent recreational outdoor activities and gardening (a peridomestic activity) were associated with a 1.4-2.3 times increased likelihood of using personal protective measures to prevent tick bites, when accounting for demographics and previous Lyme diagnosis. Most outdoor activities were more frequently reported by participants from the Midwest (n = 697), representing an older demographic, than the Northeast (n = 396). Participants from the Northeast were less likely to report use of personal protective measures to prevent tick bites, but a larger proportion of participants from the Northeast reported application of environmental pesticides targeting ticks or mosquitoes or other insects on their property (34 % of 279 versus 22 % of 616 participants) and interventions to reduce the presence of peridomestic deer compared to participants from the Midwest (e.g. 20 % of 278 versus 7% of 615 participants reported having a deer proof fence). Participants from the Midwest were more likely to kill rodents on their property (28 % versus 13 %). These differences illustrate the need for further assessment of personal behavior and tick exposure in these two Lyme disease-endemic regions to aid in targeted public health messaging to reduce tick-borne diseases.

Oral Bile Reinfusion in Chronic Percutaneous Transhepatic Cholangiodrainage.

Percutaneous transhepatic cholangiodrainage is an intervention for obstructive jaundice that, although effective in decreasing bilirubin levels, often leads to depletion of regular bile acids that subsequently cause malabsorption, diarrhea, and acute kidney injury. Bile reinfusion (BR) is a method of enteral refeeding of biliary secretions to replenish innate bile acids to the patient. In addition, BR is a low-cost alternative to exogenous bile acid replacement and abates the need for inpatient fluid resuscitation. We report oral BR in a patient with percutaneous transhepatic cholangiodrainage due to choledocholithiasis and review the literature on BR.
