169 THE SPECTRUM, ASSESSMENT AND DIAGNOSIS OF NEUROVASCULAR OPHTHALMIC PRESENTATIONS REFERRED TO AN ACUTE MEDICAL UNIT

Background

Ocular emergencies may require urgent intervention to prevent vision loss. Physicians must be confident in recognizing their presentations. However, literature published in this area is lacking.

Methods

This study assesses the consistency of the assessment of patients with neurovascular ophthalmic conditions in the Acute Medical Unit (AMU) at an Irish tertiary healthcare centre . Conditions of interest include retinal artery and vein occlusions, ischaemic optic neuropathies, and cranial nerve palsies (III, IV, and VI). Research questions to be addressed: 1. The percentage of patients referred from Eye Casualty Services (ECS) to the AMU with neurovascular ophthalmic presentations 2. The investigations performed to diagnose neurovascular ophthalmic conditions 3. How the diagnostic approach used in the AMU compares to that recommended by the literature 4. The accuracy of ECS referral diagnoses. This is an audit of 164 patients attending the AMU during a one-year period who were diagnosed with ophthalmological conditions.

Results

Of patients studied, 58 (35%) were diagnosed with conditions of interest. The most common neurovascular ophthalmic diagnosis was cranial nerve palsy (21, 36%). Among neurovascular patients, routine laboratory investigations were performed in over 90% of cases. Routine imaging was performed in over 80% of cases. Referral diagnoses from the ECS accompanied 13 (22%) of neurovascular patients, all of which were accurate.

Conclusion

Neurovascular ophthalmic conditions represent a significant proportion of ECS referrals to the AMU, and most aren’t diagnosed until after leaving the ECS. Laboratory and imaging investigations may be inappropriately utilized in some cases. More research is needed in this area.

Efeito antifúngico de extratos alcoólicos de própolis sobre patógenos da videira

Objetivou-se com este trabalho verificar a fungitoxicidade in vitro de extratos alcoólicos de própolis (EAP) sobre a germinação de esporos de Phakopsora euvitis e Pseudocercospora vitis e também sobre o crescimento micelial e esporulação de esporos de Elsinoe ampelina. Para o ensaio de inibição de germinação o EAP foi utilizado nas concentrações de 0,025; 0,05; 0,1; 0,2; 0,25 e 0,5%. Como testemunhas utilizaram-se água destilada, etanol 0,35% e fungicida azoxystrobin. No ensaio de crescimento micelial e esporulação foram utilizadas as concentrações de 0,05; 0,1; 0,2; 0,4; 0,5 e 1,0% de EAP. As testemunhas foram o meio de cultura batata-dextrose-ágar (BDA), BDA + 0,7% de etanol e o fungicida azoxystrobin. Os resultados obtidos permitiram concluir que o EAP possui baixa atividade antifúngica in vitro contra P. euvitis, P. vitis e E. ampelina, para as concentrações testadas.
