Unilateral ptosis and mydriasis secondary to presumed Lyme neuroborreliosis.

We report a case of unilateral acute-onset ptosis and mydriasis in a girl 2 years and 7 months of age from an area endemic for Lyme disease. She lacked other signs of oculomotor nerve palsy. She tested positive for Borrelia burgdorferi and negative for Bartonella henselae on serology and was diagnosed with Lyme neuroborreliosis. The ptosis and mydriasis resolved after 1 week of oral doxycycline.

PENTOSAN POLYSULFATE SODIUM-INDUCED PIGMENTARY MACULOPATHY WITH NONLEAKING CYSTOID MACULAR EDEMA SUCCESSFULLY TREATED WITH ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY.

PURPOSE: To report a case of nonleaking cystoid macular edema (CME) associated with pentosan polysulfate sodium (PPS)-induced pigmentary maculopathy. METHODS: Multimodal imaging, including optical coherence tomography, fundus photography, autofluorescence, and fluorescein angiography, was used to substantiate our diagnosis, further characterize the cystoid macular edema showed by our patient and to monitor the response to treatment. RESULTS: A 59-year-old woman was referred for decreased visual acuity and bilateral macular edema. She had been treated for interstitial cystitis with PPS for 10 years. Multimodal imaging showed the characteristic features of PPS-induced pigmentary maculopathy. Moreover, fluorescein angiogram showed nonleaking cystoid macular edema in both eyes. She was treated successfully with intravitreal injections of bevacizumab. CONCLUSION: To our knowledge, this report is the first to demonstrate that PPS-associated cystoid macular edema can be nonleaking on fluorescein angiography and responds well to intravitreal anti-vascular endothelial growth factor injections.

Cardiac morphology and function reference values derived from a large subset of healthy young Caucasian adults by magnetic resonance imaging.

AIMS: Assessment of cardiac anatomy and function by cardiovascular magnetic resonance (CMR) is accurate and reproducible and is commonly performed to clarify borderline results obtained by other techniques. Normal reference values are lacking in a large sample of young healthy adults. As CMR is increasingly solicited to discriminate normality from equivocal disease in this population, we sought to determine reliable reference values. METHODS AND RESULTS: A sample of 434 Caucasian adults aged 26 ± 4 years (45% male) without cardiovascular disease or risk factors (including obesity and smoking) underwent CMR. Blood pressure, electrocardiogram, and plasma markers (lipid profile, fasting glucose, troponin, and Nt-pro-BNP) were within normal limits and typical of a low-cardiometabolic-risk profile. End-diastolic (ED), end-systolic (ES), and stroke volumes were greater in men for left and right atria and ventricles. Left ventricular (LV) mass was higher in men. ED wall thickness of all segments was greater in men, whereas ES wall thickening (segmental function) was similar in both genders. After normalization to body surface area, all gender differences remained. Left and right ventricular volumes were lower, and left atrial volumes were higher in older individuals. In contrast, LV mass was not associated with age. CONCLUSION: This is the first large database of reference ranges for ventricular and atrial functions, volumes, and mass in young Caucasian men and women devoid of cardiovascular disease and risk factors. These data will contribute to improving the accuracy of CMR interpretation for clinical and research applications.

Visceral/epicardial adiposity in nonobese and apparently healthy young adults: association with the cardiometabolic profile.

OBJECTIVE: We investigate associations of regional adipose tissues with cardiometabolic profile of nonobese and apparently healthy young adults. METHODS: Four hundred twenty-five nonobese and apparently healthy individuals were assessed for blood pressure and fasting lipid profile, blood glucose and adiponectin. Subcutaneous abdominal adipose tissue (SAT) and ectopic fat depots (visceral abdominal adipose tissue [VAT], epicardial adipose tissue [EAT] and hepatic fat fraction [HFF]) were quantified by magnetic resonance imaging. RESULTS: According to anthropometric measurements, blood pressure and blood markers, the population (18-35 years, 54% women) had a low cardiometabolic risk. Compared to women, men had more VAT, EAT and HFF, but less SAT. Regional adipose tissues were positively correlated with each other. VAT and EAT carried significant correlations with all markers of cardiometabolic risk, while SAT and HFF correlated variably with these markers. While taking into account age and gender, SAT, VAT and EAT were associated with most cardiometabolic markers, while HFF was only associated with total cholesterol/high-density lipoprotein ratio (TC/HDL-C) and triglycerides (TG). When comparing SAT, VAT and EAT head-to-head, VAT was the only adipose tissue location maintaining significant association with most markers of cardiometabolic risk. Greater VAT (≥50th percentile) was associated with a worse cardiometabolic profile, whether individuals were overweight or normal weight. CONCLUSION: Even in nonobese and apparently healthy young women and men, accumulation of ectopic visceral adiposity in general, and of VAT in particular, is associated with a worse cardiometabolic profile whether individuals were overweight or normal weight.
