The role of retinal imaging in the management of abusive head trauma cases

Background: As retinal hemorrhage (RH) is the most frequent and reliable finding of abusive head trauma (AHT), an ophthalmology consultation should be systematically required in suspected cases. Full retinal examination through pharmacologically dilated pupil can detect the type and pattern of RHs, helping to distinguish abusive from non-abusive head trauma. Methods: We performed a retrospective analysis of a case series of 6 infants (aged 0.6-10 months) with AHT who were admitted to the Emergency Department of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome with severe intracranial hemorrhages. Children underwent full multidisciplinary assessment including dilated fundus examination, optical coherence tomography (OCT) and digital wide-field fundus photography (DWFFP – in our case RetCam). In our paper we report the clinical presentation, the ocular findings and outcome at discharge. Results: The mean age at the hospital admission was 6.28 months. In all infants, intracranial hemorrhages were found. Preretinal and intraretinal hemorrhages were detected, collecting good-quality retinal images. Conclusions: Imaging of retinal hemorrhages represents a fundamental moment of AHT diagnosis and documentation. Although RetCam is the gold standard for the acquisition of retinal images in suspected cases, OCT is extremely valuable in forensic evaluation since it can detect even small macular hemorrhages. Therefore, the combination of RetCam and OCT imaging can give relevant hints for the diagnosis of AHT, allowing to evaluate the extent, spread and morphology of RHs

Experimental data collection and modelling of dry deposition velocities for urban surfaces

Dry deposition process is recognized as an important pathway among the removal processes of radioactive pollutants in atmosphere. There is not a unique and accepted theoretical description of involved dry deposition phenomena due to the complexity of the fluid-dynamic processes that influence the deposition flux, but also because there is a lack of experimental data covering all scenarios of interest. In this paper, that is the result of a National Research Program a research activity conducted by DEIM Department of the University of Palermo and ENEA and funded by the Italian Minister of Economic Development, a new schema for parameterization of particle dry deposition velocity on urban area is proposed. The work required comparisons with some experimental data reported in literature for different particle deposition scenarios. The results show that the proposed approach can catch some aspects of phenomena involved in dry deposition processes for the examined environmental conditions with good agreements

Involvement of the anterior segment of the eye in patients with mucopolysaccharidoses: a review of reported cases and updates on the latest diagnostic Instrumentation

Mucopolysaccharidoses (MPS) are a heterogeneous group of rare inherited disorders, characterized by the lack or malfunction of lysosomal enzymes necessary for glycosaminoglycan (GAGs) catabolism, and their subsequent accumulation in many tissues and organs throughout the body. An overview of the current knowledge of corneal and anterior segment manifestations in patients with MPS was provided and clinical guidelines for their diagnosis and management were furnished. The anterior segment of the eye is usually involved in every subtype of MPS, with major complications including varying degrees of corneal opacification and raised intraocular pressure (IOP) with development of glaucoma. Their recognition and management can be very useful in the diagnosis of MPS. Novel techniques are available to objectively measure the grade and extent of corneal clouding and give information about the anatomy of the anterior chamber and the structures of the angle beyond the clouded cornea. It is advisable to take advantage of this new instrumentation in order to obtain thorough information on the ocular involvement and its related anterior chamber complications for a better management of patients with MPS, both in terms of visual prognosis and therapeutic outcome

Optic Disk Pit Maculopathy Treatment Using a Human Amniotic Membrane Patch: One-Year Results

Purpose: To report the 1-year results of human amniotic membrane patch implantation for optic disc pit maculopathy. Design: A prospective, consecutive, interventional study. Methods: Eleven eyes of 11 patients affected by optic disc pit maculopathy associated with subretinal/intraretinal fluid were included in this single-institution study. A 25-gauge pars plana vitrectomy was performed in all cases, with an implant of a human amniotic membrane patch into the optic disc pit and air was injected as endotamponade. The primary study outcome was the subretinal and intraretinal fluid reabsorption. Secondary outcomes were visual acuity improvement and postoperative complications. Results: Mean central retinal thickness gradually diminished from 512 ± 137 µm to 243 ± 19 µm, at the 12-month follow-up. The mean visual acuity improved from 20/80 at baseline to 20/32 at the 12-month follow-up. Complete fluid resorption occurred in 9 of 11 (81.8%) eyes and there was partial resorption in 2 eyes (18%). No subretinal fluid recurrence was observed during the 12-month follow-up. No intraoperative or postoperative complications were reported during the follow-ups. The amniotic membrane patch remained detectable inside the pit for the entire follow-up time. Conclusion: An amniotic membrane plug may be effective for improving optic disc pit maculopathy. All cases had an anatomical improvement and encouraging visual acuity recovery

Functional Evaluation of Eating Difficulties Scale to predict oral motor skills in infants with neurodevelopmental disorders: a longitudinal study

Aim: To assess the predictive validity of the Functional Evaluation of Eating Difficulties Scale (FEEDS) on long-term eating developmental outcomes in infants with neurodevelopmental disorders. Method: In total, 144 infants (69 females, 75 males) aged 0 to 12 months (mean [SD] 5.34mo [3.42]) with neurodevelopmental disorders and requiring enteral nutrition support, hospitalized between January 2004 and December 2017, were included. The FEEDS was administered at the onset of hospitalization. Follow-up evaluations of feeding modalities occurred at discharge and at 6 months, 12 months, and 24 months after discharge. FEEDS score was tested as a predictor of infants’ feeding modality (percutaneous endoscopic gastrostomy, nasogastric tube, mixed, oral feeding) and time to autonomous oral feeding. Percentages of false-positive and negative cases were checked. Results: Lower FEEDS scores significantly predicted infants’ feeding modality (0.40≤R2≤0.61). A 1-point increase in FEEDS score was associated with increased risk (6%–14%; p<0.05) of being non-autonomous feeders at the different follow-up points in infants who had a FEEDS score above the clinical cut-off. Interpretation: The FEEDS appears to be a clinically valid assessment to predict the presence of eating difficulties in infants with neurodevelopmental disabilities. What this paper adds: Functional Evaluation of Eating Difficulties Scale (FEEDS) significantly predicted eating difficulties in infants with neurodevelopmental disabilities. Lower FEEDS score is significantly associated with autonomous feeding at the 24-month follow-up. FEEDS cut-off identified infants at low-risk and high-risk for eating disorder

Functional and morphologic findings at four years after intravitreal bevacizumab or laser for type 1 ROP

BACKGROUND AND OBJECTIVE: To compare morphologic and functional status at age 4 years for patients treated in one eye with laser photocoagulation and the other eye with intravitreal bevacizumab (IVB) injection for Type 1 retinopathy of prematurity (ROP). PATIENTS AND METHODS: In this single-center, randomized, controlled trial, best-corrected visual acuity (BCVA) in logMAR was obtained along with spherical equivalent refraction (SER), fluorescein angiography (FA), optical coherent tomography (OCT), and OCT angiography (OCTA). RESULTS: Eighteen babies (36 eyes) were selected for this study. BCVA and SER were similar in the two groups, but six patients had anisometropia of 4 diopters or more. IVB-treated eyes tended to have thinner foveal thickness than laser-treated eyes (mean difference: \u20135.33 pixels; 95% confidence interval, \u20139.62 to \u20131.05). CONCLUSION: Although the differences found here are minimal between the IVB-treated and laser-treated groups, further long-term evaluation of not only FA, but also OCT and OCTA, are needed in larger studies
