Alfaar, "Pathological findings of Retinoblastoma in Egypt; implementing CAP protocol in developing countries.", International Society of Genetic Eye Diseases and Retinoblastoma meeting., Gent, Belgium, 2013. Abstract

Introduction / Purpose: Retinoblastoma is the most common intra-ocular tumour of childhood. Radiotherapy and chemotherapy has improved survival for the disease over the last 40 years. Looking for prognostic criteria is one of the major research areas that inspires disease management teams all-over the world. Many protocols were designed over the years to correlate the presence of certain pathological and/or molecular features and prognosis of the disease. Children’s Cancer Hospital Egypt 57357 (CCHE) is a new cancer center in Egypt that serves about 25-40% of the pediatric oncology population in the country. The aim of this study is to present the histopathological findings in Egypt leading pediatric oncology center and impact of implementing CAP protocol on the improvement of patient care. Materials & Methods: CCHE Retinoblastoma study team implemented College of American Pathologist (CAP) protocol of Retinoblastoma version 3.0 (Based on AJCC/UICC TNM, 7th edition) for examining enucleation specimens. Pathology team has conducted an internal training for pathologists. New electronic case report forms (eCRFs) were designed for reporting the progress. Real-time online statistical analysis system was integrated with eCRFs. Implementation included prospective processing and data entry of new specimens properties beside revising of all specimens prior to the implementation of the protocol. Healthcare quality measures included required time for releasing the reports. Results: Between July 2007 and May 2013 we’ve examined 198 enucleation specimens. Mean of all ocular diameters was 22.2 mm. Mean Optic nerve stump length was 6.35 mm. Invaded structures included Cornea (5.3%), Anterior chamber (15.4%), Iris (8.3%), Lens (5.9%), Ciliary body (18.3%), Choroid, (72.2%), Sclera (17.2%), and Orbital tissue (7.1%). Any degree of Optic Nerve invasion was noted in 51% of specimens while surgical margin was involved in 10.8%. Validation rules in eCRFs helped the team to complete missing data and provide systematic reporting. Integrated online analysis system provided a real-time reporting facility for detecting protocol implementation progress. Conclusions / Significance: Implementing CAP retinoblastoma protocol resembled a roadmap for improving patients’ care. It supported the systematic reporting of cases, decreasing errors and missing data and provided research informatics team with a blueprint for developing a real-time monitoring system. This system can be integrated in the practice of emerging teams to ensure adherence to quality measures.

Introduction: Diabetic retinopathy (DR) is the most common diabetic eye disease worldwide and a leading cause of blindness. The number of diabetic patients will increase to 552 million by 2034, as per the International Diabetes Federation (IDF).

Aim: With advances in computer science techniques, such as artificial intelligence (AI) and deep learning (DL), opportunities for the detection of DR at the early stages have increased. This increase means that the chances of recovery will increase and the possibility of vision loss in patients will be reduced in the future.

Methods: In this paper, deep transfer learning models for medical DR detection were investigated. The DL models were trained and tested over the Asia Pacific Tele-Ophthalmology Society (APTOS) 2019 dataset. According to literature surveys, this research is considered one the first studies to use of the APTOS 2019 dataset, as it was freshly published in the second quarter of 2019. The selected deep transfer models in this research were AlexNet, Res-Net18, SqueezeNet, GoogleNet, VGG16, and VGG19. These models were selected, as they consist of a small number of layers when compared to larger models, such as DenseNet and InceptionResNet. Data augmentation techniques were used to render the models more robust and to overcome the overfitting problem.

Results: The testing accuracy and performance metrics, such as the precision, recall, and F1 score, were calculated to prove the robustness of the selected models. The AlexNet model achieved the highest testing accuracy at 97.9%. In addition, the achieved performance metrics strengthened our achieved results. Moreover, AlexNet has a minimum number of layers, which decreases the training time and the computational complexity.

BACKGROUND: P-glycoprotein (P-gp) is a membrane efflux pump which is overexpressed in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) and promotes Type 2 inflammation. Glucocorticoids (GC) are substrates of P-gp suggesting that overexpression may additionally contribute to GC resistance in CRSwNP. This study aims to determine whether P-gp inhibition using verapamil enhances mometasone retention and efficacy in nasal polyp explants.

METHODOLOGY: IRB approved study in which organotypic polyp explants were exposed to mometasone (4.15 μg/mL) and verapa- mil (125 μg/mL) as mono and combination therapy. The effect of verapamil on mometasone tissue retention over time was deter- mined using HPLC. The effect of verapamil on mometasone anti-inflammatory function was determined using ELISA for secreted IL-5. Groups were compared using Kruskal-Wallis test.

RESULTS: P-gp expression strongly and significantly inversely correlated with mometasone retention 1hr after exposure, with a ne- arly 6-fold reduction in tissue retention between the lowest and highest P-gp expressing polyp explants. P-gp inhibition reversed this effect and significantly improved mometasone retention at 1hr relative to mometasone alone. The combination of mome- tasone and verapamil significantly reduced IL-5 secretion relative to vehicle control and outperformed either treatment alone.

CONCLUSIONS: Our study confirms that P-gp contributes to mometasone resistance. This P-gp mediated resistance was successfully reversed by addition of the P-gp inhibitor verapamil. Verapamil further significantly enhanced the anti-inflammatory effect of mometasone when given as a combination therapy.
