Late-Onset Chronic Corneal Fistula Following Phototherapeutic Keratectomy: A Case Report and Importance of Early Detection.

BACKGROUND We report a case of late-onset chronic fistula in a decompensated cornea after multiple ocular surgeries and a recent phototherapeutic keratectomy (PTK). CASE REPORT A 73-year-old woman presented to our service with a past ocular history of bilateral chronic angle closure glaucoma and pseudophakic bullous keratopathy in the left eye. Given a history of long-term uncontrolled glaucoma with advanced disc cupping and poor visual potential, the patient underwent multiple palliative procedures, including, most recently, a PTK. Few years later she presented with a spontaneous late onset of slowly appearing corneal leak on fluorescein staining upon routine clinical examination. Corrected distance visual acuity was hand motion and intraocular pressure (IOP) was 40 mmHg in the affected eye. Serial anterior segment optical coherence tomography (AS-OCT) sections were obtained, which aided in understanding the current presentation and revealed distinctive multilayer corneal changes during the healing process. The patient was successfully managed with cyanoacrylate corneal gluing and ocular hypotensive medications, which halted the corneal leak. CONCLUSIONS We report a case of a rare finding of corneal fistula in an eye with multiple previous ocular surgeries, and provide an explanation of the possible etiopathogenesis. We also highlight the pivotal role of AS-OCT for evaluating such cases and stress the importance of early detection of similar subtle leaks in the setting of a formed anterior chamber, which can often be missed, carrying a risk of infection.

Outcomes in ED patients with non-specific ECG findings and low high-sensitivity troponin.

Background: Although some emergency department risk stratification tools consider non-specific ECG findings as an aid in disposition decisions, their clinical value in patients with an initially low high-sensitivity cardiac troponin I (hsTnI) is unclear. Objective: Our purpose was to determine if non-specific ECG (ns-ECG) findings are associated with 30-day major adverse cardiac events (MACE) in ED patients presenting with suspected acute coronary syndromes (ACS) who have a low initial hsTnI. Methods: Using the prospective Siemens Atellica hsTnI Food and Drug Administration submission observational database, we conducted a retrospective cohort study of the association between ns-ECG findings (defined as left bundle branch block [LBBB], ST depression [STD], or T-wave inversions [TWI]) and 30-day MACE (death, myocardial infarction, heart failure hospitalization, or coronary revascularization). Eligible patients presented with suspected ACS to one of 29 US EDs from April 2015 to April 2016, had stable vital signs, a blood sample for hsTnI (Siemen's Atellica, Siemens Healthineers, Inc, Malvern, PA) obtained at 1, 3, and 6 hours after ED presentation, and were followed for 30 days. The relationship between 30-day outcome, initial hsTnI, and ns-ECG was evaluated using chi-square testing. Results: Of 2676 enrolled, 1313 patients met the inclusion criteria and are included in the analysis. Median (interquartile range) age was 62 years (54, 72), 54% were male, with 56% white, and 39% African American. Median (interquartile range) times from symptom onset to presentation and presentation to specimen collection were 92 (0, 216) and 146 (117, 177) minutes, respectively. The most common presenting symptoms were chest pain (84%), followed by dyspnea (9%). ECG findings were categorized as T-wave inversion or non-specific T wave changes (42%), ST depression ns-ECG ST changes (16%), or LBBB (2%). Thirty-day MACE occurred in 72 (5.5%) patients, with coronary revascularization (35 patients, 2.7%) and heart failure (25 patients, 1.9%) being the most frequent outcomes. In patients with an initial hsTnI below the limit of quantitation (LOQ) of 2.5 ng/L (n = 449), there was no association between ns-ECG changes and 30-day MACE (P = 0.42). If the hsTnI was ≥LOQ (2.5 ng/L), there were increased rates of 30-day MACE and ns-ECG findings (P = 0.01). Conclusion: In ED suspected ACS patients without unstable vital signs, and an initial hsTnI less than the LOQ (2.5 ng/L), ns-ECG findings are not associated with 30-day major adverse cardiac events. The use of ns-ECG findings in ACS disposition should be considered in the context of hsTnI levels.

Surgical Versus Medical Management of Necrotizing Enterocolitis With and Without Intestinal Perforation: A Retrospective Chart Review.

Background Necrotizing enterocolitis (NEC) is a debilitating disease that predominantly afflicts premature neonates, although it can also affect term neonates. The clinical features of the ailment vary widely and range from transient feed intolerance to life-threatening complications such as septicemia and disseminated intravascular coagulation. While surgery is usually only reserved for severe cases, such as those presenting with intestinal perforation, the role of surgical management in cases of NEC without perforation remains elusive. Methods A retrospective chart review of patients, three years in duration, was conducted and studied confirmed cases of NEC. The clinical presentations studied included cases of NEC with pneumatosis intestinalis, fixed bowel loop, pneumoperitoneum, and abdominal wall erythema. The patients were divided with regards to their intestinal perforation status and with pertinence to the treatment modality employed (medical or surgical). The results in either group were eventually analyzed in terms of the overall survival rate. Results A total of 48 patients were included in the study, of which 79.16% presented without perforation and 20.83% with perforation. Of the study participants included, 26 were females and 22 were males. Pertinently, no gender predominance was appreciated. In patients without perforation, medical management was noted to boast a lower mortality rate when compared with surgical intervention (15.6% vs 50.0%, respectively). In patients with perforation, the overall mortality was noted to hover at 50.0%, which was higher than that encountered in the non-perforation group. Conclusion In patients with NEC without perforation, surgical treatment confers no comparative therapeutic advantage when compared with medical management alone. Conservative management with broad-spectrum antibiotics including metronidazole yields equally favorable outcomes in such cases.

Evaluation of the Quality and Readability of Online Sources on the Diagnosis and Management of Osteochondral Lesions of the Ankle.

OBJECTIVE: Patients frequently use the internet as a source to obtain health information. The purpose of this study was to evaluate the quality and readability of online resources on the diagnosis and treatment of ankle osteochondral lesions (OCLs). DESIGN: Three search terms ("ankle cartilage defect," "cartilage injury," "ankle cartilage damage") were entered into 3 search engines (Google, Yahoo, and Bing). The first 20 websites from each search was collected excluding websites intended for health care providers. The quality of the websites were evaluated using the DISCERN instrument, JAMA benchmark, and a Quality rating criteria specific to ankle OCL. The readability was assessed using Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL). Statistical analysis was performed using one-way analysis of variance. RESULTS: A total of 41 websites were reviewed. The mean quality ratings were poor across the assessment tools: DISCERN = 38.5 ± 9.0 (range, 23.7-56.7) out of 80; JAMA = 1.0 ± 1.1 (range, 0-3.3) out of 4; and Quality rating criteria = 11.3 ± 4.6 (range, 4-20.7) out of 24. The mean FRE and FKGL were 40.7 ± 32.0 (range, -152.3 to 60.2) and 13.5 ± 10.8 (range, 8.4-80.7), respectively; higher than the recommended reading level for patients (fifth grade). CONCLUSIONS: The quality and readability of credible sources for ankle OCL were poor, which could lead to misinformation. This study should guide the improvement of online information on ankle OCL.
