Retina-sparing suprachoroidal intraocular foreign body resulting in cyclodialysis cleft.

Purpose: Suprachoroidal intraocular foreign bodies (IOFBs) are an exceedingly rare manifestation of ocular trauma. Here we present a unique case of a metallic wire tracking from the cornea through the suprachoroidal space, and remarkably sparing the retina and lens. The patient attained an excellent visual outcome after management of resultant cyclodialysis cleft. Observations: A 34-year-old male experienced a penetrating IOFB while operating a rotary wire brush. He presented to the emergency department where posterior involvement of the IOFB was confirmed on CT scan. He underwent emergent pars plana vitrectomy, during which the IOFB was found to be located underneath intact retina and choroid on scleral depression. The wire was removed through the entry wound, which was self-sealing. At follow up, intraocular pressure was 3 mmHg with findings of hypotony. A cyclodialysis cleft was confirmed with ultrasound biomicroscopy. Cycloplegic and photocoagulation treatments were attempted, but ultimately direct cyclopexy was performed to successfully repair the cleft. One year after the initial incident, visual acuity is 20/25 and IOP is 17 mmHg. Conclusion and importance: Cyclodialysis cleft is a rare sequela of penetrating ocular injury. Clinicians should consider the presence of a cyclodialysis cleft in the setting of postoperative hypotony and confirm either with gonioscopy or other anterior segment imaging methods. Despite failure of conservative therapies, our patient had an excellent visual outcome following surgical closure of the cleft.

Myopericarditis after messenger RNA Coronavirus Disease 2019 Vaccination in Adolescents 12 to 18 Years of Age.

OBJECTIVES: To characterize the clinical course and outcomes of children 12-18 years of age who developed probable myopericarditis after vaccination with the Pfizer-BioNTech (BNT162b2) coronavirus disease 2019 (COVID-19) messenger RNA (mRNA) vaccine. STUDY DESIGN: A cross-sectional study of 25 children, aged 12-18 years, diagnosed with probable myopericarditis after COVID-19 mRNA vaccination as per the Centers for Disease Control and Prevention criteria for myopericarditis at 8 US centers between May 10, 2021, and June 20, 2021. We retrospectively collected the following data: demographics, severe acute respiratory syndrome coronavirus 2 virus detection or serologic testing, clinical manifestations, laboratory test results, imaging study results, treatment, and time to resolutions of symptoms. RESULTS: Most (88%) cases followed the second dose of vaccine, and chest pain (100%) was the most common presenting symptom. Patients came to medical attention a median of 2 days (range, <1-20 days) after receipt of Pfizer mRNA COVID-19 vaccination. All adolescents had an elevated plasma troponin concentration. Echocardiographic abnormalities were infrequent, and 92% showed normal cardiac function at presentation. However, cardiac magnetic resonance imaging, obtained in 16 patients (64%), revealed that 15 (94%) had late gadolinium enhancement consistent with myopericarditis. Most were treated with ibuprofen or an equivalent nonsteroidal anti-inflammatory drug for symptomatic relief. One patient was given a corticosteroid orally after the initial administration of ibuprofen or an nonsteroidal anti-inflammatory drug; 2 patients also received intravenous immune globulin. Symptom resolution was observed within 7 days in all patients. CONCLUSIONS: Our data suggest that symptoms owing to myopericarditis after the mRNA COVID-19 vaccination tend to be mild and transient. Approximately two-thirds of patients underwent cardiac magnetic resonance imaging, which revealed evidence of myocardial inflammation despite a lack of echocardiographic abnormalities.

Modified Senning Procedure for Correction of Atrioventricular Discordance With Total Anomalous Pulmonary Venous Return, Atrial Situs Inversus, Dextrocardia, and Bilateral Superior Venae Cavae.

The Senning and Mustard baffles remain important techniques for the treatment of congenitally corrected transposition (cc-TGA), isolated ventricular inversion, and D-transposition of the great arteries with delayed presentation. We describe the treatment of an 8-month old infant with atrioventricular discordance, ventriculoarterial concordance, and dextrocardia with atrial situs inversus. A modified Senning procedure was performed through the "left-sided" atrium. Modifications of the Senning and Mustard baffles remain important tools in the treatment of rare conditions like isolated ventricular inversion.

Cardiotoxicity associated with the synthetic cannabinoid, K9, with laboratory confirmation.

Synthetic cannabinoids have been popular recreational drugs of abuse for their psychoactive properties. Five of the many synthetic cannabinoids have been recently banned in the United States because of their unknown and potentially harmful adverse effects. Little is known about these substances. They are thought to have natural cannabinoid-like effects but have different chemical structures. Adverse effects related to synthetic cannabinoids are not well known. We provide clinical effects and patient outcome following K9 use. In addition, we briefly review synthetic cannabinoids. We present a 17-year-old adolescent boy with chest pain, tachycardia, and then bradycardia associated with smoking K9. Two synthetic cannabinoids, JWH-018 and JWH-073, were confirmed on laboratory analysis. In addition to the limited current data, we demonstrate harmful adverse effects related to toxicity of 2 synthetic cannabinoids. Further studies are needed.

Myocardial infarction associated with use of the synthetic cannabinoid K2.

Designer drugs have been problematic over the years. Products such as K2 and Spice, which contain synthetic cannabinoids, are marketed as incense and are widely available on the Internet and at various specialty shops. The effects are reported as cannabis-like after smoking them. In addition, use of these synthetic cannabinoids will not appear on a routine urine toxicology screen. Recently, K2 became a popular alternative to marijuana among youths. Health implications of these designer drugs are not completely understood. Little has been reported about the harmful effects of K2. We report here the first (to our knowledge) cases of myocardial infarction (MI) after smoking K2. Three patients presented separately to the emergency department complaining of chest pain within days after the use of K2. Acute MI was diagnosed in each case on the basis of electrocardiogram changes and elevated troponin levels. Coronary angiography was performed, and the results were normal for the first 2 patients. The incidence of ST-elevation MI is low among teenagers, and association with drug use should be suspected. Public education and awareness need to be heightened about the possible health implications of K2.

Left ventricular function improves after pulmonary valve replacement in patients with previous right ventricular outflow tract reconstruction and biventricular dysfunction.

Congenital heart defects that have a component of right ventricular outflow tract obstruction, such as tetralogy of Fallot, are frequently palliated in childhood by disruption of the pulmonary valve. Although this can provide an initial improvement in quality of life, these patients are often left with severe pulmonary valve insufficiency. Over time, this insufficiency can lead to enlargement of the right ventricle and to the deterioration of right ventricular systolic and diastolic function. Pulmonary valve replacement in these patients decreases right ventricular volume overload and improves right ventricular performance. To date, few studies have examined the effects of pulmonary valve replacement on left ventricular function in patients with biventricular dysfunction. We sought to perform such an evaluation.Records of adult patients who had undergone pulmonary valve replacement from January 2003 through November 2006 were analyzed retrospectively. We reviewed preoperative and postoperative echocardiograms and calculated left ventricular function in 38 patients.In the entire cohort, the mean left ventricular ejection fraction increased by a mean of 0.07 after pulmonary valve replacement, which was a statistically significant change (P < 0.01). In patients with preoperative ejection fractions of less than 0.50, mean ejection fractions increased by 0.10.We conclude that pulmonary valve replacement in patients with biventricular dysfunction arising from severe pulmonary insufficiency and right ventricular enlargement can improve left ventricular function. Prospective studies are needed to verify this finding.
